Embodiment Construction

[0014] see figure 1 , Figure 2, the arrow in the figure shows the direction of water flow.

[0015] In this embodiment, a "herringbone"-shaped steel frame is adopted, and its two "herringbone"-shaped struts are supported in the river bed along the direction of water flow, thereby forming the upstream strut 1 and the back-water strut 2.

[0016] It is shown in the figure that on the river bed, along the direction of the width of the river channel, the steel skeletons are arranged at intervals, and the distance of the intervals can be 3-5 meters. , and between the steel skeleton and the fixed pile 3, located on the pole 1 on the water-facing surface, pulling each other with steel cables 4, and laying steel wire mesh 5 on the steel cables 4, the surface of the steel mesh 5 is covered with woven cloth 6.

[0017] In order to facilitate the construction, the bottoms of the upstream pole 1 and the rear pole 2 can be set as cone feet as shown in the figure. It can be inserted into ...

Abstract

The overflow dam features its A-shaped steel skeletons arranged in certain interval inside river in the water flow direction. It has fixed piles on river banks, steel cables stretched between each two adjacent steel skeletons and between the steel skeleton and the fixed pile upstream face, and steel wire net spread onto the steel cables, and woven fabric on the surface of the steel wire net. It has low cost, easy construction, firm structure and long term acting. The present invention is used not only in field irrigation but also in blocking burst for fighting blood.

Description

Technical field: [0001] The invention relates to a dam structure in water conservancy facilities, more specifically a rolling dam. Background technique: [0002] The rolling dam was built to raise the water level for farmland irrigation. Especially for mountainous areas, the river water is very shallow in the rainy season, but in the rainy season, when the flash floods arrive, the river water surges. In order to store water, the farmers piled up the sand and rocks in the river, spread woven cloth and pressed the sand and rocks to form a temporary dam. However, due to the lack of foundation, after a heavy rain, the mountain torrents almost completely washed away the temporary dam. In order to irrigate the farmland, the farmers had to rebuild it again. It is routine to repeat construction many times a year, which consumes a lot of labor but has little effect. Some places have invested in the construction of reinforced concrete dams, but due to insufficient funds, the dam f...
