Slope protection interlock block adapted to large deformation through rotation of double shafts

Abstract

A slope protection interlock block adapted to large deformation through rotation of double shafts comprises an interlock block body and two spherical segment hinges. The interlock block body is of a cuboid structure, spherical-segment-shaped protrusions and spherical-segment-shaped debosses matched with the spherical-segment-shaped protrusions are arranged on the front and rear surfaces and the left and right surfaces of the interlock block body respectively to form the two spherical segment hinges, and the interlock blocks are connected through the spherical segment hinges on the front and rear surfaces and / or the spherical segment hinges on the left and right surfaces. Compared with existing interlock block structures, the slope protection interlock block can adapt to deformation of a damp slope in any direction, closing of interlock block gaps is ensured, impact on safety of a dam caused by rainfall infiltration due to opening of the interlock block gaps caused by deformation is prevented.

Description

technical field [0001] The invention relates to the field of side slope protection, in particular to a side slope protection chain block capable of biaxial rotation and adapting to large deformation. Background technique [0002] Slope instability has always been the most concerned issue in slope engineering, and rainfall infiltration is often the biggest cause of slope instability. In order to prevent the impact of rainfall infiltration on the stability of the slope, various measures and means are adopted in the project to prevent rainfall infiltration. and anchor cables to reinforce and prevent seepage of the slope to ensure the safety of the slope. [0003] Affected by surrounding construction, changes in groundwater level, and rheology of the soil, the natural slope will undergo some deformation. The existing masonry slope protection and interlocking block slope protection have limited adaptability to deformation, and cracks will occur on the masonry slope surface. As ...

AI Technical Summary

Problems solved by technology

[0003] Affected by surrounding construction, changes in groundwater level, and rheology of the soil, natural slopes will undergo certain deformations. The existing masonry slope protection and interlocking block slope protection have limited adaptability to deformation, and cracks will occur on the masonry slope surface. As well as problems such as the separation between interlocking blocks and the fracture of interlocking structures, rainfall infiltration channels are formed, which in turn lead to local rainfall infiltration, and scour and erode the lower soil. As the damage continues to develop, it will eventually affect the stability of the overall slope ; For the upstream and downstream dam slopes in water conservancy projects, since the slope protection structure is laid during the completion period, the outer contour of the dam body will be deformed to a certain extent due to the influence of water storage load, post-construction deformation of the dam body, and rheology of earth and stone materials , the existing chain block slope protection has limited applicability to deformation, and cannot guarantee that the chain blocks will remain closed after the deformation of the dam slope, and it is easy to form water seepage channels, which will affect the safety of the dam slope
