Reinforcement protective structure of large spoil disposal area in mountainous area

Abstract

The invention discloses a reinforcement protective structure of a large spoil disposal area in a mountainous area, which is capable of effectively solving the technical problem of instability of the large spoil disposal area in the mountainous area, reducing water loss and soil erosion and avoiding the anthropogenic geologic hazard problems caused by the abandoned spoil. The reinforcement protective structure comprises anti-slide piles, a retaining plank, a macadam reversed filter, a main water seepage blind ditch, branch water seepage blind ditches, an annular catchwater, a longitudinal drainage trench, catchwaters and a drainage chute, wherein the anti-slide piles are arranged on an exit slope toe of the spoil disposal area and distributed at intervals along the cross direction of a groove; the retaining plank is arranged on the side of the anti-slide piles near to the spoil disposal area; the macadam reversed filter is filled behind the retaining plank; the main water seepage blind ditch is longitudinally arranged along the center of the groove on the bottom of the spoil disposal area; along the centre of the groove on the bottom of the spoil disposal area, the branch water seepage blind ditches are distributed in the shape of branches toward slopes on two sides and communicated with the main water seepage blind ditch; the annular catchwater is arranged along the surrounding mountain having more than 1m elevation from the top of the spoil disposal area, and stretched and connected to a natural groove on the exit of the spoil disposal area; the longitudinal drainage trench is arranged along the top center of the spoil disposal field and communicated with the natural groove; the catchwaters are arranged in the shape of branches from the longitudinal drainage trench of the spoil disposal area to the top two sides of the spoil disposal area and communicated with the longitudinal drainage trench; the drainage chute is arranged outside the retaining plank.

Description

technical field [0001] The invention relates to the reinforcement and protection of dreg sites for railways, highways, water conservancy and the like, and particularly relates to a reinforcement and protection structure for large dreg sites in mountainous areas. Background technique [0002] With the construction of a large number of road projects, water conservancy projects and local infrastructure in my country, a large number of excavated dregs have appeared. According to the requirements of environmental protection, it is necessary to centrally discard the dregs. Due to terrain constraints in mountainous areas of our country, there is often a huge amount of dregs excavated in engineering construction, and dregs can only be concentrated and discarded in mountainous trenches. It not only meets the requirements of environmental protection, but also has a reinforcement and protection structure for the dregs field with simple construction technology and saving engineering inv...
