Problems solved by technology

In some areas with relatively complicated construction conditions, it is inevitable to cut and overlap the geogrid. At present, the lap joints between the grid meshes are mostly connected by binding, and the adjacent two pieces of grid mesh are connected by binding belts. Bundled together, if the overlapping parts are subjected to a large load, such an overlapping method is likely to cause concentrated stress on the grid mesh. When the concentrated stress is too high, the connection parts of the grid belts will be pulled down, causing the phenomenon of threading , and cause a certain displacement of the grid mesh, which seriously affects the reinforcement performance of the geogrid and brings certain safety hazards to the project

Abstract

The invention discloses a steel-plastic geo-grid network connecting device. The steel-plastic geo-grid network connecting device consists of a shell body, bolts, clamping sheet rooms, insertion holes,clamping sheet slots, a communication slot, slide slots, clamping sheets, engaged teeth, pull plates, slide slots and geo-grid joints. According to the steel-plastic geo-grid network connecting device disclosed by the invention, the clamping sheets and the clamping sheet slots are arranged inside the connecting device, so that lap joint between adjacent two steel-plastic geo-grid networks is changed into connection between grid belts, integrity and continuity of the lap joint part of the geo-grid are greatly improved, and a phenomenon that the grid belts are damaged by pulling as a result ofrelatively great concentrated stress is avoided, and therefore, reinforcing quality of a soil layer and engineering safety are improved.

Description

technical field [0001] The invention relates to a connection device for steel-plastic geogrid nets applied in the field of soft foundation reinforcement engineering, and is especially suitable for reinforcement areas where construction conditions are complex and a large number of splicing of grid nets is required. Background technique [0002] In the treatment of weak foundations such as roadbeds, dams, and slopes, in order to increase the bearing capacity of the soil layer and prevent disasters, geogrids are often used as reinforcement materials to improve the performance of the soil and reduce the difference in roadbeds. settlement. In some areas with relatively complicated construction conditions, it is inevitable to cut and overlap the geogrid. At present, the lap joints between the grid meshes are mostly connected by binding, and the adjacent two pieces of grid mesh are connected by binding belts. Bundled together, if the overlapping parts are subjected to a large load...
