Embodiment Construction

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following in conjunction with the attached figure 1 And the specific embodiment will further illustrate the present invention.

[0019] as attached figure 1 As shown, a geogrid nested with ribs for a pile network structure includes longitudinal main ribs 1, transverse main ribs 2, longitudinal auxiliary ribs 3 and lateral auxiliary ribs 4, The longitudinal main ribs 1, the transverse main ribs 2, the longitudinal auxiliary ribs 3 and the transverse auxiliary ribs 4 are respectively composed of a plurality of polyester fiber bundles 6, each of the longitudinal and transverse The polyester fiber bundles 6 are arranged in parallel and side by side, the longitudinal and transverse polyester fiber bundles 6 form two planes up and down, and the interweaving of the longitudinal main stress ribs 1 and the transverse main stress ribs 2 forms the main stress by b...

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...
