The principles and reasonsThe objective, The format of the Weir upstreamConsiderations in constructing a Weir Various types of dam construction. The integrated Dept. Semi-permanent Dept. FAI permanent.Benefits of a Weir upstreamMaintenance of the FAI tam time streamsThe success of the operation.And expansion of the result.Unit responsibleBuild a Weir upstream,,,,Profited? An integrated upstream dam Intended for use in the sediment trap and scrap materials and helping to reduce speed or slow the flow of water, which is in the construction of this integrated upstream dam. The Creek should be 3-5 meters of width, depth of about 0.50 – 1.00 m.An integrated upstream dam Design summary of 6. FAI mixed pork stall. FAI mixed bamboo Hessian mixed dam FAI mixed wire mesh FAI mixed stones throw FAI mixed wisdomWeir is a Weir pig stall mixed using a wooden cradle hit a surrounding frame. Inside the packing materials such as straw sacks packed soils overlay. Straw sacks packed sand and cement ratio 1:10 or stone tiling in the Paddock side of pork, which is dependent on the material, we can always find a local.Using materials1. small logs of diameter 6 inch long about 1-1.20 m.2. Small logs of diameter 4-6 inches long, depending on the width of the Creek.3. straw sacks packed soil or sand filling with cement or stone-1:10.4. nail size is 5-6 inches.Method of construction1.Survey and selection area.2.Adjust the area. Dredge deep seabed, Huay DIN issued 0.5 – 1.00 meters along. Created by, digging into the side of a Creek by 0.50 – 1.00 m.3.Paste the logs crosswise, a Creek along the dig.4.Clock master logs firmly. 0.30 meters deep5.Paddock wood paste, pork Nail, mounted together.6.Wangkrasop straw packing straw sacks packed with sand or cement, 1:10 or place the rock in the Paddock space pork.7.Use the hit logs not overwrite after Weir are strong, then using crutches back, Weir.FAI mixed bamboo Weir is a Weir bamboo blend that is suitable for areas with a lot of bamboo-bamboo using a cradle and make a frame. Inside the packed clay and bamboo, in principle, adhere to the strength of the soil. Weir's back sort of stone is suitable for large areas that First Order Stream.Using materials1. bamboo trunk size 1 – 1.5 inches in length, 1 – 1.50 m.2. Bamboo trunk-size 3-4 inches in length, depending on the width of the Creek.3. the t 1 m long bamboo4. the big stones.5. soil.Method of construction1. survey and selected areas.2. Adjust the area. Dredge deep seabed, Huay DIN issued 0.50 – 1.00 m wide and approx. 1.00 m along the construction, digging into the side of a Creek by approximately 0.50 – 1.00 m.3. place the transverse bamboo Creek, where the hole for the head and between about 0.80 – 1.00 m (depending on the Creek width).4. place the drill at the head of the bamboo, and the end of the tip, poke around 20 cm long by the hole by a Creek, a Creek that lay bamboo and placed along the Creek, then straight transverse bamboo size 1 – 1.5 inches deep into the soil to hold pegs approx. 0.30-0.50 m and remove the drill bamboo, according to the prepared insert switch cross together until the desired level.5. use a bamboo barrier placed on the inside of the ferry's bamboo placed spacious front and back Creek Weir Weir.6. put the soil in between the gap of the wool and bamboo side on both sides when the height of 0.50 m long bamboo core diameter 1 – 1?-inch, to anchor the soil, see nailed down, distance, as appropriate, and then enter the soil, the Weir finished bamboo pegs into the core to firmly anchor the soil and strong.7. remove the stone sorting area in front of and behind the Weir.Weir is a Weir with a sack that is suitable for the Creek that has less slope water flow was not very large, very wide, and the Creek. The area is called First Order Stream.Using materials1 straw sacks.2. Soil or sand mix cement ratio 1:103. The wooden main verse 4 inches in diameter, or 1 – 1.5 inch size bamboo approximately 1.00 1.50 metres –Method of construction1. survey and selected areas.2. Adjust the area. Dredge clay bottoms Huai issued approximately 0.5 m deep 1.00 m wide.3. wangkrasop soil or sand mix cement overlays, about 3 or 4 rows.4. The main use of round wood or bamboo rhizomes nailed down on sacks of burlap to hold strong and then overlay another level wangkrasop you want and remove the logs or round bamboo nailed down on sacks to hold firmly. Which is the distance of the main view as appropriate.FAI mixed mesh is divided into three.1. fai mixed mesh type 1 concrete lintels2. mesh combination Weir 2 do not pour concrete lintels.3. mesh combination Weir 3 no Teda base and lintel.FAI mixed mesh type 1 concrete lintelsMethod of constructionAdjust the area firmly and smooth using a stone Foundation, 100 cm in width and approximately 80 – place the mesh aluminium which are bound to a steel frame and pour the concrete path with 10 cm thick, then use a large stone at the place the switch to full mesh frame height 50 cm wide, 30 cm length by width of the Weir (by deep penetration to the Creek in the walls of both sides. By 50 – 100 cm). Then, using a big stone, place the switch overwrites, another layer is always the full mesh edges. Use the steel bracket and then pour the concrete periodically overwrite another layer thickness approx. 10 cm to the rocks and strong mesh using a large stones placed Weir finished the front and back of Weir, about 30 – 50 cm high strength or might use a bamboo pegs are piling the stone smooth defense, it will help even more durable Dept.If you want to retain water, use sand, cement mixer packed in sacks of Fang, a ratio of 8:2 front overlay Weir, which can add capacity as the height of the sack.FAI mix
