Embodiment Construction

[0035] The invention connects the assembled wall panel and the geogrid by adopting an elastic shock-absorbing connection device, so that the reinforced earth retaining wall has sufficient flexibility, and it is not easy to cause rigid damage that is difficult to repair under the action of earthquake load, which increases the adaptability of the wall panel. The ability of the soil to deform, while the use of spliced ​​prefabricated block panels makes construction easier. The introduction of waterproof geomembrane makes the reinforced soil not easy to be invaded by water body, and the folded line turn-up technology of geogrid greatly reduces the slope deformation.

[0036] The present invention adopts such as figure 1 , 2The prefabricated rigid-flexible reinforced earth retaining wall shown includes a prefabricated wall panel concrete block 1, an elastic damping connection device 2, a geogrid device 5, a foundation 6 and a filling foundation 10, and the prefabricated wall pane...

Abstract

The invention belongs to the field of slope protection and earthquake resistance. The problems that an existing reinforced retaining wall panel is poor in deformation adaptability at a rigid joint, and a flexible panel-free reinforced soil slope is large in occupied area are solved. The invention provides a construction method of an assembly type rigid and flexible combined elastic anti-seismic reinforced soil retaining wall. According to the reinforced soil retaining wall, by using geogrids, assembly type wall panels and elastic damping devices, the deformation adaptability of the retaining wall is greatly enhanced, and the occupied area of a project is reduced; the scouring damage of a slope surface is reduced; under the action of earthquake load, connecting steel plates of elastic damping connecting devices are used as splicing formworks, wall panel building blocks are allowed to have certain dislocation but not be damaged, and therefore damage to joints of the wall panels and the geogrids is reduced; and the geogrids on an upper layer and a lower layer are separately arranged, so that the stress is more reasonable, the structure is more stable, and the deformation fatigue lifeis long.

Description

technical field [0001] The invention belongs to the field of slope protection and earthquake resistance and disaster reduction, and specifically relates to a construction method of a rigid and flexible combined geogrid reinforced retaining wall using a spring shock-absorbing connection device, which is a medium and small geotechnical synthetic material for geotechnical engineering Composite reinforced retaining structure. Background technique [0002] Reinforced retaining walls have been widely used in the stability and reinforcement of hillsides, foundation pit slopes and river banks due to their superior bearing capacity and seismic stability. After many years of engineering practice experience at home and abroad, when encountering earthquake disasters, the reinforced earth retaining wall can effectively reinforce or block unfavorable geological bodies. For example, strengthen landslides, collapses, rock piles, block falling rocks, mudslides, etc. [0003] However, accor...
