Abstract

The invention relates to a simple sediment retaining siltation promotion dam used for being mounted in a ditch. The simple sediment retaining siltation promotion dam comprises two supporting piles anda transverse partition board. The two supporting piles are inserted into soil bodies on the two sides of the ditch correspondingly and arranged oppositely. The transverse partition board is mounted between the two supporting piles. The distance from the lower end of the transverse partition board to the bottommost end of the bottom of the ditch is less than or equal to 5 cm. Water at the bottom of the ditch is blocked by the transverse partition board, water flow is slowed down, sediment at the bottom of the ditch is gradually accumulated on one side of the upstream of the transverse partition board, and the bottom of the ditch can maintain the same height as the transverse partition board all the time, so that scouring of water flow to the bottom sides of the original ditch is effectively reduced, and the ditch is prevented from being deepened and broadened. The simple sediment retaining siltation promotion dam related to in the invention is simple in structure, easy to manufacture and convenient to install and has good economic efficiency, practicality and wide applicability.

Description

technical field [0001] The invention relates to a water and soil loss prevention project for a channel, in particular to a simple sand-retaining silt-promoting dam and a construction method thereof. Background technique [0002] Soil erosion is the number one environmental problem in my country, and a large amount of land resources are lost every year due to soil erosion. Especially in mountainous and hilly areas, soil erosion gullies are easily formed by heavy rain erosion. If not treated in time, the gullies will become wider and deeper, resulting in serious water and soil erosion and destroying land resources. Currently, the commonly used ditch protection The project is to build a silt-retaining dam. The main function of the sediment-retaining silt-promoting dam is to store and regulate the runoff sediment, and prevent the incision of the ditch and the expansion of the ditch bank. [0003] Divided by dam materials, the common sediment-retention dams include earth dams, ...
