An embedded two-way geogrid

Abstract

The invention discloses an embedded bidirectional geogrid. The embedded bidirectional geogrid comprises parallel-arranged grid bands, parallel-arranged connecting plates and parallel-arranged connectors. Through holes are formed in the surface of each grid band at equal intervals, rectangular through holes are formed in the side faces of each grid band at equal intervals, and the rectangular through holes vertically communicate with the corresponding through holes. The two across corners of the surface of the two ends of each grid band are each fixedly provided with a first clamping block and a second clamping block, and the surface of the side, close to the corresponding second clamping block, of the first clamping block and the surface of the side, close to the first clamping block, of the second clamping block are both provided with corrugated troughs. Positioning shafts are fixed to the two sides of one end of each grid band, and positioning holes are formed in the two sides of the other end of each grid band. The embedded bidirectional geogrid can be combined at will according to the site conditions, the geogrid can be combined in a high strength mode without special equipment, rapidness and convenience are achieved, the reliability of connecting positions of the geogrid is high, and the geogrid has a certain tensile strength. In addition, the geogrid is easy to transport and is not limited by width and can meet the construction requirement of various special occasions.

Description

technical field [0001] The invention belongs to the field of geotechnical grids, in particular to an embedded bidirectional geotechnical grid. Background technique [0002] During the construction of subgrades, embankments, slope protection and reinforced retaining walls, and soft soil foundations, accidents such as sags, cracks, landslides, and collapses may occur due to geological structures and soil layers. In order to ensure the quality of the project, soil reinforcement is often adopted, that is, geogrids are used to reinforce and reinforce the soil to keep it as a whole to prevent the lateral displacement of the soil. [0003] In the prior art, the geogrid is formed by one-time molding or combined welding into a mesh grid structure from the rib belt. The problems of the one-time formed geogrid are: it cannot be fully stretched, the length and width of the roll are limited, and the transportation is limited due to the extra length; it is easy to break when backfilling ...

AI Technical Summary

Problems solved by technology

The problems of the one-time formed geogrid are: it cannot be fully stretched, the length and width of the roll are limited, and the transportation is limited due to the extra length; it is easy to break when backfilling and rolling; there are many lap joints during laying, which consumes labor and consumables. The construction cost is increased; the problem of the combined welding structure is that welding requires special equipment, and on-site welding cannot be realized; and there are problems such as weak solder joints and easy desoldering
