Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that due to the repeated expansion and contraction of expansive soil due to water absorption and water loss, when the time is long, it is easy to cause cracks in the clay layer, which in turn leads to the problem of poor slope stability

Embodiment Construction

[0045] The following is attached Figure 1-5 The application is described in further detail.

[0046] refer to figure 1 and figure 2 , an expansive soil slope revetment structure, the expansive soil slope 1 includes a slope top 11 and an inclined slope surface 12, and the side of the slope surface 12 away from the slope top 11 is a slope bottom 13. The angle between the slope surface 12 and the ground is 45°, also can be 60°. The surface of the slope top 11 is provided with a cement layer 2, and the cement layer 2 is embedded with fixed piles 21 implanted inside the slope top 11, and the fixed piles 21 are vertically inserted into the inside of the slope top 11. The fixed piles 21 improve the fit between the cement layer 2 and the slope top 11 , making it difficult for the cement layer 2 to move relative to the surface of the slope top 11 .

[0047] Such as figure 1 and image 3 As shown, a number of cement boards 3 are arranged on the slope 12 , and the end of the ceme...

Abstract

The invention relates to an expansive soil slope bank protection structure. According to the expansive soil slope bank protection structure, an expansive soil slope comprises a slope top and a slope surface, the side, away from the slope top, of the slope surface is a slope bottom, a plurality of cement plates are arranged on the slope surface, reinforcing meshes are arranged in the cement plates,the faces, close to the slope surface, of the cement plates are in a step shape, built-in piles implanted into the slope surface are pre-buried in the cement plates, a cement layer is arranged on thesurface of the slope top, fixing piles implanted into the slope top are pre-buried in the cement layer, the ends, away from the slope bottom, of the cement plates are connected with the cement layer,spacing sections are formed between the adjacent cement plates, clay layers are laid on the spacing sections, vegetation layers are planted on the clay layers, a drainage ditch is formed in the slopebottom, and a retaining wall is arranged between the drainage ditch and the slope surface. The expansive soil slope bank protection structure has the effects of reducing the possibility of cracks ofan expansive soil slope protection layer and improving the stability of the expansive soil slope. The invention further provides a construction method of the expansive soil slope bank protection structure.

Description

technical field [0001] The application relates to the field of expansive soil slope protection, in particular to an expansive soil slope revetment structure and a construction method thereof. Background technique [0002] Expansive soil is mainly composed of strongly hydrophilic clay minerals montmorillonite and illite. It is a highly plastic cohesive soil with expansive structure, multiple cracks, strong expansion and contraction, and strength attenuation. It is also a typical unsaturated soil. . Expansive soil brings harm to engineering activities, and its strength attenuation characteristics caused by repeated expansion and contraction deformation due to water absorption and loss of water have long-term potential damage to engineering facilities. [0003] In the existing technology, there have been researches on expansive soil slopes and some progress has been made. For example, the Chinese invention patent with the notification number CN104264694B discloses a constructi...
