Abstract

A rib belt nested geogrid for a pile net structure relates to the technical field of geogrids, solves the problem that the structure of the geogrid does not meet the construction requirements, and comprises longitudinal main stress rib belts, transverse main stress rib belts, longitudinal auxiliary stress rib belts and transverse auxiliary stress rib belts, The longitudinal polyester fiber bundles and the transverse polyester fiber bundles are parallelly arranged. the longitudinal polyester fiber bundles and the transverse polyester fiber bundles are in an upper plane and a lower plane, main stress rib belt cross nodes are formed at the interlacing positions of the longitudinal main stress rib belts and the transverse main stress rib belts through binding yarns, and auxiliary stress rib belt cross nodes are formed at the interlacing positions of the longitudinal auxiliary stress rib belts and the transverse auxiliary stress rib belts through binding yarns. Due to the nesting effect of the grids, the auxiliary stress rib strips are nested into a mesh structure formed by the main stress rib strips in a crisscross manner to form a grid form similar to'large meshes nested with small meshes and wide strips nested with narrow strips', so that the reinforcement effect and the stress coordination effect are fully exerted.

Description

technical field [0001] The invention relates to a geogrid, in particular to a rib-embedded geogrid for a pile network structure. Background technique [0002] The pile network structure is a very important measure and construction procedure for the treatment of soft soil subgrades such as high-speed railways and expressways. It plays an important role in controlling settlement and avoiding subsidence of subgrade. Generally, in the foundation treatment process, a pile network structure is adopted, and the lower soil is strengthened by vertical piles to form a composite foundation reinforcement area. Most of the upper load is borne by the piles, and the load is transmitted to the deep soil through the piles. The geogrid on the top of the pile is horizontally reinforced to form a composite foundation reinforcement area, so that the pile, net and soil work together to bear the upper load as a whole. It has the advantages of small settlement deformation and quick completion, ea...
