Waterproof energy dissipation supporting structure for expansive soil slope

Abstract

The invention relates to a waterproof energy dissipation supporting structure for an expansive soil slope. The supporting structure comprises a plurality of EPS composite boards, anchor rods (1) and soil nails (2), wherein the EPS composite boards are embedded in expansive soil (9) and distributed in an array mode. The anchor rods (1) are fixedly connected with the EPS composite boards in a penetrating and inserting mode, the soil nails (2) are fixedly connected with the EPS composite boards in a penetrating and inserting mode, and concrete (8) is further arranged on the outer sides of the EPS composite boards. The EPS composite boards comprise an EPS board (13) close to the side slope of the expansive soil (9) and an inorganic resin panel (4) away from the side slope of the expansive soil (9). Compared with the prior art, the waterproof energy dissipation supporting structure has the advantages that the stability of the expansive soil side slope is improved, the expansive soil side slope protection structure is protected, the service life of the expansive soil side slope protection structure is prolonged, the side slope construction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of expansive soil slope protection, in particular to a waterproof and energy-dissipating support structure for expansive soil slopes. Background technique [0002] Expansive soil slope is a special case and important in slope engineering. The special case is because expansive soil slope contains viscous minerals such as montmorillonite and illite, which have the characteristics of water absorption and dehydration shrinkage, but expansive soil in the natural state It has high strength and low compressibility, but once it encounters water, the strength of expansive soil will decrease sharply. For other rocks and soils, although the strength of water will also change, the range will not be too large. Therefore, the waterproofing of expansive soil slope engineering has always been a difficult problem in the field of geotechnical engineering; the main reason is that expansive soils are widely distributed in my country, espec...

Problems solved by technology

[0007] Publication No. CN202010952558.5 is an invention patent for an assembled anchor frame beam structure with EPS elastic cushion suitable for expansive soil slopes. By laying EPS elastic cushions on both sides of the reinforced concrete concave beam prefabricated unit, the slope can be improved. The construction efficiency and quality of the support project, the invention has some similarities with a waterproof material and construction technology suitable for expansive soil slopes to some extent, but the invention mainly utilizes an elastic property of EPS, At the same time, a waterproof feature of the EPS board is also applied to a certain extent (secondary). The main consideration is a combination of the EPS material and the frame beam, and it does not consider changing the structural form of the EPS board and making full use of its waterproof and moisture-proof. and shock absorption features to use this material more effectively and economically
