Description

Anti-leakage structure and construction method of silt dam drainage in wind and water composite erosion area

Technical Field

The invention relates to the technical field of anti-leakage reinforcement of silt dams, and in particular to a drainage anti-leakage structure of a silt dam in a wind-water composite erosion area and a construction method thereof.

Background technique

The sandy and coarse sand area in the middle reaches of the Yellow River is the main source of sediment in the Yellow River Basin. The soil erosion in this area is complex, intense and difficult to control. It has long been one of the factors restricting the high-quality social and economic development of the Yellow River Basin. Among them, the combined erosion of wind and water causes serious soil and water loss on slopes, ditches and river basins. Silt dams are set up in soil erosion areas to avoid excessive soil and water loss and to store water for irrigation of farmland. This is a conventional control measure.

When leakage occurs in the silt dam, due to the environment in which the silt dam is located, a large amount of silt and other impurities are attached to the slope of the silt dam, and the lower part of the silt dam is in mud and sand. In this way, when the leakage area is in the above position, the leakage area needs to be cleaned.

There is no better measure in the existing construction methods to remove impurities such as silt on the slope and the bottom of the silt dam, which makes the subsequent pouring operation extremely troublesome, and the poured concrete is difficult to form an integral part with the silt dam, which makes the cast structure strength weak and cannot achieve the effect of firmly reinforcing the silt dam.
