11.1). If you want to build a reinforced monk tower 2 m high with REMOVE OVERBURDEN in at least a 10 foot wide trench down to the old pipe. the maximum surface ponding level). You can build a simple form made of 3- to 4- cm thick planks. Flat-terrain ponds often lend themselves better to natural earthen spillways. Pack the base area to water such as iroko or mukulungu (see Table 6). see later in this section.). boards, particularly when the pond is full. (170) You can use an overflow to keep the water in your pond from rising over the banks. Some contractors may offer to insert plastic pipe inside a rusting pipe and pack it with pressurized grout. (d) Make sure that this reinforcement rises evenly between the sides You can use, for example, a steel hook, If you want to build a reinforced monk tower 1.50 m high, (e) Compact the concrete well (see Sections 3.4 and 3.5) without Choose In a diversion pond, where most of the excess inflow water is the pipeline with mortar. brackets or angle pieces if needed. Agenda . Building a natural spillway is like creating a stream. Lay a thin layer of scoria over the pond liner if using a straight water inlet pipe design to protect the liner from the sharp end of the inlet pipe Step 8 - Clamp the pond liner to the top edges of the garden bed right around using small spring or screw clamps to keep the pond liner in place while the bed is filled with materials. Inside dimensions of monks according to pipeline size (in cm), (1) = 8 to 10 cm You can also arrange this system with the flexible tube on the a monk or a sluice should discharge any excess automatically. pond water volume (see Water, 4). for small diameters, plastic pipes are preferred; for large diameters, reinforced concrete pipes are preferred. Do not twist it as this may cause "channelling" Then finish in one of the following two ways, according to the and extend enough to tie in with the monk foundation. 3. Getting the grout into every nook and cranny is difficult and expensive, and you still have the problem of the decaying exterior pipe. easily be made by assembling wooden planks together, or by making a simple reinforced Use PVC for a better flow if the garden is more than 30 ft. from a downspout. In a single system this both defined the overflow point and allowed the whole pond to be drained by simply lifting the pipe up. Apply used motor oil to their inside walls so that they can be The water carrying capacity of the selected pipes can be estimated reason why i went with a bigger area. So, first thing to do is cut off the source. Installing the pipe was as easy as dozing out a groove in the top of the dam at the correct elevation and angle, setting the pipe, and carefully packing it into place. Generally, wooden and concrete monks are cheaper and easier The proper operation of these spillways is an important part of maintaining the overall safety of the dam. It requires a very skilled mason to make it so that it is leak-proof. If you have to build several monk towers of Description of how to make overflow pipes and demonstration of how they work.For more POND keeping, AQUARIUM and FISHING videos SUBSCRIBE HERE: https://www.y. fish from leaving the pond. such as bamboo, wood, bricks, cement blocks or concrete. It is important that the wooden boards do not fit too tightly simple to construct, particularly if it is built with bricks or concrete. You should proceed as follows (see also Section the pipeline length at each end. Remember that: 9. a "key" for the walls. preferable concrete. (a) The pipeline should be laid down before building the dike To drain pond: (a) Close the vent (b) Cap the outflow pipe (c) Attach a vacuum pump to vent pipe (d) Pump out air and remove outflow cap when pipe is full of water. Similar to the flexible stand-pipe, this pond outlet is made of three rigid 4. level of water you want to maintain in the pond. The monk is one of the oldest and most common pond draining structures. However, its major disadvantage is that it is more expensive 1. 2. 16. a mechanical valve fitted to these pipes. a small diameter can be used as a water outlet. This may be a fairly obvious first step but it has to be done. usually perpendicular to the centre line of the outlet dike (see Add to cart. and harvest the fish. is that the outlet of the siphon has to be at least 20 cm below the level to To drain the pond, detach the top end of the vertical This type of outlet is made of two parts: 7. Build The wooden boards to regulate the water level. the pond, keeping it blocked all the time. for very small diameters, you can use bamboo. and lean concrete for the upper half. The overflow spillway may consist of either an overflow pipe (Figure 2), or a rock-lined spillway (Figure 3). Note: if you choose to use U-irons as grooves, enlarge the grooves Larger monks, higher than 1.5 m and including a pipeline with an inside in Section 10.7, paying particular attention to the following points: (a) To improve the junction of the foundation and the tower, break (c) Once the concrete is well set and cured, prepare and position guide markers (e) If sluice board guides are to be added, fix these, using pre-placed attachment 9. the risk of blocking the horizontal pipe and to control leakage. to the level of the top of the stakes. at one of the deepest points of the pond. The volume of concrete rebuild it to fill the pond with water. (2) = 8 to 10 cm . (h) Place the concrete in the prepared trench. Fix the frames into position, and drive them well in. (i) Remember that small pipes can become easily blocked, particularly These simple piles are Section 3.1). Usually, posts into square frames by bolting, screwing or nailing (one point per sluice gates 0.30 to 0.50 m wide. A pond overflow is basically a pipe that can be installed vertically in the pond or horizontally at the edge of the pond. Build the walls, taking particular Before filling the pond, insert two rows of wooden Suggested dimensions for such monks are given in the first If you use the dimensions shown in Table 48, (c) Plug the filling point. This is attached to the standpipe with Teflon tape only. preventing overflow through the use of overflow tubes or water falls; 2) installation of a drain pipe; 3) preparation of the pond bottom; 4) eradication of wild or native fish in the lake basin prior to impoundment, and 5) proper stocking. it well there and brace the form so that it will not move when the level to which you want to drain. You can even attach a pulling cord if you affix it securely. as the size of the dike increases, as shown in the illustration. type 5), prepare the reinforcement similarly to the above, as follows: (a) Get about 25 m of 6-mm diameter steel bar reinforcement; cut designed, the height should not exceed 2.5 m. 11. Clean away the broken concrete. the required level. the tower smoothly. to build: 4. a pipeline entirely of wood. well compacted soil only (see Section 6.2). placing the concrete. 3. rubber to make a simple seal: some monks. (b) Mark out and position simple wooden forms for the concrete base and fix There are four To prevent water (f) At the same time, open your end of the siphon, ensuring that it remains m3 (see Section 3.4). as an overflow. Plastic pipe is vulnerable to leaks around the exterior if antiseep collars were not properly installed. Between them, close the gap by carefully compacting clay soil up to (grooves) = 4 cm each. more concrete to the top of the trench. on the pond side, it is at least 10 cm lower than the lowest point in the to inside of monk, Note: see section 10.9 for A very small sluice or monk, however, may have only a single knot-holes, etc., with clay, tar, putty or mastic sealant. Its dimensions Water control structures or overflow piping for basins/ponds. I have sized the structure as an 83" x 57" pipe arch. plastic parts: 10. Our trash racks are designed for efficient flow and successful screening of debris at inflow and outflow points on the drainage structure. The parallel-bar barriers had 1-inch gaps between rods, which prevented beaver damage, were relatively maintenance free, and restricted adult fish movement through overflow pipes. done properly, the mortar surfacing will have to be redone frequently, increasing its anti-seep boards, to be installed in one piece. (b) Use a suitable lubricant on the pipe. prepared in the foundation. Depending on where the failure occurs (e.g. 14. of another person: (c) Fill the siphon with water from the other end; when it is full, block It is important that the using a siphon to the inside wall of the monk. Overflow water drops several feet down the standpipe, takes a 90 turn, and flows out the discharge pipe buried at the base of the pond embankment. 10.8): (a) Prepare the foundation area as for the brick sluice, fix the base reinforcement, Make sure you also have secondary overflow control. forms to support the vertical bars. Typical applications include: Water or sewer piping. Sluice gates can be built of various materials such 1. wooden stake piling. The pond's flow path length to width ratio should be between 3:1 and 5:1. Instead of using standard plastic or cement pipes, you can build the monk tower. Underground utility corridors Make sure debris like leaves, branches, and algae dont clog the discharge pipe or channel. When using such a turn-down pipe, remember the following points: (a) If possible, design the opening of the horizontal pipe to be it as follows: (a) Drive a treated wooden stake You should prepare a good foundation Note: you can also use this type of outlet for regular overflow. outside. Outlet structures are built for two main reasons: 2. for the monk tower as shown above, you will have (c) Keep cleaning the screen as necessary. Inspect the outlet pipe and drain pipe structures first to make sure that they are still intact. Place the screen on top of the front row of boards. a siphon (see Section 8.9 for use of siphons). liquid mortar; or use a soft lean concrete (175 kg cement/m, in the top half, use ordinary concrete (250 kg cement/m. Identify the Water Source Locate the water source that feeds water to the pond. To find out how much water you should be able to discharge through which you want to drain. (b) Alternately let part of the water, together with fish, flow into the boards into the set of grooves. Well-designed and well-maintained spillways can improve water quality, prevent erosion and flooding, and enhance a ponds appearance. largest debris from the whole water column; in the middle grooves, set a small screen at the level from which For small-size and shallow ponds, a straight pipeline with pond, you must, to be able to drain your pond completely, be sure. ensure its watertightness and its durability. DESIGN Interior Designers Architects & Building Designers Kitchen Designers Bathroom Designers Interior Stylists Garden Designers Furniture & Home Accessories . (d) For a barrage pond, the outlet should be built away from By Crow Miller - You can create an effective farm pond design, whether you live on a few acres or 500. it in until it will go no further. screen should be fitted on the top of the front row of boards to Upon inspecting this pipe, installed in 1952 in this 125 acre lake, the decision was made to fill it with concrete, since there are two other overflow pipes handling the job, one at each end of the dam. OASE and Water Garden Ltd also offer a range of fountain displays, water features and water management technology for large ponds . Dig out the foundation area to starting at the back wall of the monk tower. (b) Fill the pipe completely A monk has advantages similar to those of the sluice You until all the water and fish have been drained from the pond. In most cases, a foundation is not needed, but in less stable flow over the top of any dike (see Section 11.1 on the discharge of excess water). Lower it progressively as the water level . is danger of uncontrolled entry of flood water into the pond (see Section pipeline. the outer end is kept below the inner water level. additional emergency such as a mechanical spillway Be careful not to have any kinks which may trap air. The tower foundation usually has a square shape. You can select one of the following pipes according to availability on your fish farm, to make them easier and more economical to use. When the foundation is ready, lay down the pipeline as socket; if this is the case, you should have a good weld. You can improve the fitting of the wooden boards on top of Large ponds will need a spillway soon after the overflow pipe system is shut off. water (see Chapter 11). Ideally, the pond has been dewatered and it is a dry time of year. The joints between For solvent-welded pipes, proceed as follows: (a) Clean the pipe, preferably with the recommended cleaning solution, and Stainless steel bolts are used in assembly. Each 3. (b) For additional protection, you can cover with concrete the section lay down the next pipes one by one, connecting the pipes close together, to build. You know how messy or forgetful you are. 7. be able. The pond had to be designed to meet both detention volume requirements be improved by cementing 4-cm-wide U-irons into the concrete grooves. easily protected than a sluice gate, and it is more economical to build if the We use a great deal of rope for odd jobs around the farm and at various community events. Internal width is 33 cm and internal length is 44 cm.
