Abstract

The invention provides a construction method of a side slope supporting seepage ditch, which comprises the following steps: carrying out lofting excavation on a side slope, and carrying out manual finishing to obtain a drainage space with a preset depth; the drainage space is sequentially filled with concrete and cement mortar, and a drainage bottom plate is formed; pervious concrete is poured on the drainage bottom plate to form a sewer reverse filtration drainage system; constructing at the bottom of the side slope to obtain drainage holes, and covering cement mortar on the surface of the reverse filtration drainage system of the seepage ditch to form a closed layer, so as to form the supporting seepage ditch. And the pervious concrete is used as the drainage layer and the inverted filter layer, so that the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of drainage construction, in particular to a construction method for slope support seepage ditches. Background technique [0002] There is a large amount of earth excavation in the slope section. After the excavation of the soil, the force balance of the rock and soil is broken. When the groundwater of the slope body is high, under the action of the water flow, soil diseases are very likely to occur. Especially for expansive rock and soil, the permeability coefficient is small, and the strength drops rapidly when exposed to water. Under the action of repeated drying and wetting, cracking, deformation, and even serious diseases such as collapse and slippage will occur. In order to ensure the stability of the slope, the method of slowing down the slope and supporting the seepage ditch is adopted. The relevant seepage ditch is composed of flake drainage layer, sand and pebble filter layer, sealing layer and retaining wa...
