Problems solved by technology

However, in current projects, especially in slope or retaining wall projects, the interaction between geogrid and soil has not been fully utilized due to material or manufacturing process problems of traditional geogrids, which seriously affects the processing of geogrids. tendon effect

Embodiment Construction

[0009] see figure 1 with figure 2 , a preferred embodiment of the present invention is described as follows in conjunction with the accompanying drawings: L-shaped three-dimensional geogrid should keep the L shape of transverse rib 1 and carry out on-site laying upwards, and the backfilling soil layer exceeds the height of L-shaped transverse rib 1 by 2 to 3 times before mechanically Compaction, other construction site laying steps are the same as ordinary geogrid.

[0010] This L-shaped three-dimensional geogrid includes a transverse rib 1 and a longitudinal rib 2 of a one-way or two-way geogrid. The transverse rib 1 of the geogrid is a three-dimensional transverse rib with an L-shaped cross section, forming an L-shaped three-dimensional geogrid. grille.

[0011] The three-dimensional transverse rib 1 with an L-shaped cross section increases the bite force between the transverse rib and the soil (sand), thereby increasing the pulling force of the geogrid. The above-mentio...

Abstract

The invention relates to an L-shaped solid geogrid. A transverse rib of the geogrid is a solid component the cross section of which is of an L shape. The L-shaped cross section increases the occlusal force and the friction force between the transverse rib and the soils (sand) so as to greatly increase the drawing force of the geogrid. The solid transverse rib with the L-shaped cross section increases the whole stability of the solid ribbing and increases the ribbing effect of the solid ribbing. The L-shaped solid geogrid has reasonable stress, can greatly improve the ribbing effect of the geogrid, has excellent engineering application value and economic benefit, and is particularly suitable for side slope or retaining wall engineering.

Description

technical field [0001] The invention relates to an L-shaped three-dimensional geogrid. The transverse rib of the L-shaped three-dimensional geogrid is an L-shaped three-dimensional member, thereby playing the role of three-dimensional reinforcement, which can significantly strengthen the reinforcement effect of the geotechnical grid, especially Suitable for slope or retaining wall works. Background technique [0002] Since Hemi Vidal proposed the concept of reinforced soil in 1963, geotechnical reinforcement technology has been widely used in water conservancy, railways, highways, ports and construction projects, solved many technical problems in civil engineering, and achieved good social and social achievements. economic benefits. Geogrid is one of the more commonly used geotechnical reinforcement materials at present, and it is mostly used in reinforced soil subgrade engineering, foundation treatment and fill slope protection engineering. However, in current projects, e...
