Geocell and its construction method

Abstract

The invention relates to a geocell and a construction method thereof. The geocell comprises a plurality of stripes and micro-pile structures for connecting adjacent stripes, wherein every two adjacent stripes are partially attached to form a joint node, the part, between every two adjacent joint nodes, of each stripe forms a cell side wall, and one cell is defined by four cell side walls through the corresponding joint nodes; each micro-pile structure comprises a first columnar body and a second columnar body which are attached to two sides of each joint node, and the first columnar body, the second columnar body and the joint node are welded into an integral structure. By arranging the micro-pile structures at the joint nodes of the geocell, the inter-stripe welding area is increased, and the peel strength of weld nodes is improved, so that the structure of the geocell is more stable. Further, with adoption of the micro-pile structures, the area of contact with soil mass is increased, frictional resistance is increased, constraining force for the soil mass is increased, and accordingly, deformation and settlement of a subgrade are reduced.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a geocell and a construction method thereof. Background technique [0002] Geocells are widely used in traffic engineering. Among them, geocells can be used as a cushion to deal with weak foundations and increase the bearing capacity of the foundations. They can also be laid on slopes to form slope protection structures, and can also be used to build retaining structures. [0003] A geocell is an array of reinforced cells similar to a "honeycomb" structure, which can be filled with filler, which can be non-cohesive soil, sand, gravel, ballast or any other type of aggregate. Constraints are provided in all directions, and internal force vectors act on all walls within each cell. [0004] China's prior patent (patent application number: 201580009986.1, invention name is perforated geocell) discloses a geocell formed by a plurality of polymer strips, adjacent strips are joined alo...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art, provide a geocell and its construction method, and solve the problem that the connection between the adjacent strips of the existing geocell is combined by welding lines, which makes the connection weak and affects the cell structure. Stability, and the peeling strength of the welding line is low, it is easy to break the welding line during paving
