Ecological retaining structure of expansive soil slope and construction method

Abstract

The invention discloses an ecological retaining structure of an expansive soil slope. The ecological retaining structure comprises rectangular retaining splicing blocks with a length-width ratio lessthan 1.5 to 1, a three-dimensional net, green plants, anchor rods and flexible connection structures, and the surface layer of the slope is covered with the three-dimensional net; the retaining splicing blocks are arranged above the three-dimensional net, and the anchor rods sequentially penetrate through the retaining splicing blocks and the three-dimensional net from top to bottom to anchor theretaining splicing blocks to the surface of the slope; the retaining splicing blocks are divided into reinforced concrete layers, rubber layers and water absorbing and moisturizing layers from top tobottom in the thickness direction, and vertical through holes are formed in the middles of the retaining splicing blocks; the green plants are planted in the through holes; and the flexible connectionstructures are arranged between the retaining splicing blocks and used for forming the flexible connection between the retaining splicing blocks. The invention further discloses a construction methodof the ecological retaining structure of the expansive soil slope. According to the ecological retaining structure, by changing the retaining form and connection mode, and combining with green vegetation, the strength of the slope can be ensured, and meanwhile the expansion and contraction damage easily caused by the engineering characteristics of the expansive soil is reduced.

Description

technical field [0001] The invention belongs to the technical field of slope engineering, and in particular relates to an ecological retaining structure and a construction method of an expansive soil slope. Background technique [0002] Slope protection has always been an ancillary project that is an important consideration in engineering construction, especially the support treatment of expansive soil slopes requires more consideration. Expansive soil has the engineering characteristics of swelling when exposed to water and shrinking when it loses water, and the slope of expansive soil is recognized as a major management problem. The common treatment method is to use rigid retaining structures, which are still in accordance with the treatment procedures of ordinary slopes in the process of use, without emphasizing the damage caused by the expansion and contraction deformation of expansive soil, resulting in the existing expansive soil edge The effect of the slope retaining...
