Abstract

The invention provides a vertical soil engineering grid, comprising rib belts which are arranged vertically and in a 45-degree cross grain, the space between the rib belts form a rhombus grid cavity, an injection molding node is arranged at the connection position of the two rib belts, the injection molding node is formed by integrated injection molding a middle cylindrical pin and a fixed piece on the periphery, the two connected rib belts are arranged in parallel, a plurality of sets of upper and lower cracks are arranged evenly at corresponding positions, strip rib blocks are formed between each set of upper and lower cracks, and the cylindrical pin is passed through the spaces formed by a plurality of strip rib blocks and rib belts. After the vertical soil engineering grid is paved in a foundation, the stretching resistance, the yield strength, the shearing force, the lock force and the frictional resistance are improved evidently, great intensity of pressure in the construction process can be borne, the soil body compacted density is increased, the soil fixing ability is increased greatly, the uneven sedimentation is improved evidently, the sedimentation after the construction is reduced, the vertical soil engineering grid is anti-chemical erosion, the engineering stress has time effect, the safety is good and the intensity is high.

Description

technical field

[0001] The invention relates to a geogrid, which treats soft foundations in the construction of highways, railways, ports, wharves, municipalities and other projects to reduce uneven settlement and post-construction settlement of road foundations, in particular to a vertical type geogrid. technical background

[0002] The existing plastic tensile geogrids, polyester geogrids, and steel-plastic geogrids are all flat grids, and the joint strength of the longitudinal and lateral rib belts is poor, and the displacement of the rib belts is large. If the bearing strength of the grid is offset, it will cause uneven settlement of the road. Chinese Patent No. 200620074598X discloses an integrated geogrid for soft foundation treatment, which is formed by longitudinal and transverse rib strips arranged in a grid. , The transverse rib belt is injection-molded to form an integral structure. Although this grille improves the joint strength and the overall anti-settling ...
