Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0030] The present invention provides an ecological retaining structure for expansive soil slopes, comprising a square or rectangular retaining splicing block 1 with an aspect ratio of less than 1.5:1, a three-dimensional net 2, green plants 3, anchor rods 4 and a flexible connection structure 5. The three-dimensional net 2 is covered and arranged on the surface of the slope; the support splicing block 1 is arranged above the three-dimensional net 2, and the anchor rod 4 passes through the support splicing block 1 and the three-dimensional net 2 from top to bottom to splice the support The block 1 is anchored on the slope surface; the splicing block 1 is divided into a reinforced concrete layer 11, a rubber layer 12, and a water-absorbing and moisturizing l...

Abstract

The invention discloses an ecological retaining structure for expansive soil slopes, which includes rectangular retaining splicing blocks with an aspect ratio less than 1.5:1, a three-dimensional net, green plants, anchor rods and a flexible connection structure, and the three-dimensional net covering is arranged on The surface layer of the slope; the support block is set above the three-dimensional network, and the anchor rod passes through the support block and the three-dimensional network from top to bottom to anchor the support block on the slope surface; the support block is in the thickness direction From top to bottom, it is divided into a reinforced concrete layer, a rubber layer, and a water-absorbing and moisturizing layer, and there is a through hole in the middle of the support splicing block; green plants are planted in the through hole; the flexible connection structure is set between the support splicing blocks. A flexible connection is formed between the pair of retaining splicing blocks. The invention also discloses a construction method of the ecological retaining structure of the expansive soil slope. The invention can reduce the expansion and contraction damage easily caused by the engineering characteristics of the expansive soil while ensuring the strength of the side slope by changing the form and connection mode of the support and combining with the green vegetation.

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...
