Combined permeable geogrid

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a combined permeable geogrid. The combined permeable geogrid comprises square frames and a connecting device, a plurality of transverse baffles and a plurality of vertical baffles are arranged on the inner sides of the square frames in parallel, permeation holes are formed in the transverse baffles and the vertical baffles in a penetrating mode, and the two ends of each transverse baffle and the two ends of each vertical baffle are fixedly connected with the corresponding inner side of the square frame correspondingly. The multiple transverse baffles and the multiple vertical baffles are vertically crossed and connected together to form a grid, fixing holes are formed in the connecting points of the transverse baffles and the vertical baffles in a penetrating mode, reinforcing nails are inserted into the fixing holes, battens are fixedly connected to the outer sides of the four edges of the square frames, and a plurality of connecting holes are formed in the battens in a penetrating mode. By arranging the connecting device, in the using process, when one square frame bears pressure from the surface of a road, the square frame can transmit the borne pressure to the adjacent square frames through the connecting device, so that the bearing capacity of the square frames is improved, and the situation that the square frame is dislocated in the road construction process due to uneven stress is avoided.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a combined permeable geogrid. Background technique [0002] Geogrid is a main geosynthetic material. Compared with other geosynthetics, it has unique performance and efficacy. It is often used as reinforcement of reinforced soil structure or composite material. According to the types, geogrids are mainly divided into unidirectional geogrids and bidirectional geogrids. Compared with unidirectional geogrids, bidirectional geogrids have wider applications and are used for roadbed reinforcement of various roads and railways. , large parking lots and wharf yards and other permanent load-bearing foundation enhancements. [0003] In order to meet the needs of different scenarios, existing geogrids sometimes have permeable holes on the crosspieces and vertical pieces of the grid, so as to prevent corrosive water from staying on the crosspieces and vertical pieces of the grid a...

Problems solved by technology

[0003] In order to meet the needs of different scenarios, the existing geogrids sometimes have permeable holes on the crosspieces and vertical pieces of the grid to prevent corrosion The water stays on the horizontal and vertical bars of the grille and causes damage to the grille. Especially when it is used for road construction, because there is more water in road construction, it is especially necessary to do a good job of anti-corrosion work, but more holes will cause damage to the grille. Affect the bearing capacity of crosspieces and vertical pieces, and the grids used in road construction often need to splice multiple geogrids together. Due to the lack of suitable connecting devices between adjacent two geogrids, when Misalignment is prone to occur when the road is uneven or sloped, which affects the safe use of geogrids
