Description

Technical Field

[0001] The utility model relates to the technical field of geocells, in particular to a stress-sensing geocell. Background Art

[0002] The geocell structure enables it to adapt to the terrain and form a stable structure after being filled with soil, sand, gravel or other materials. The application of geocells is very wide, including but not limited to the reinforcement of highway and railway roadbeds, river management, prevention of soil erosion and landslides, as well as for landfills, mining operations and green infrastructure projects. In engineering, geocells can enhance the bearing capacity and stability of the foundation, improve the engineering properties of soft soil, and reduce the impact of environmental factors on structural stability.

[0003] The existing geocells are concealed projects. Especially during the use of slopes and flexible retaining walls, when the structure of the geocell is damaged by external forces, the staff cannot monitor its deformation and take precautions in advance. The connection nodes in the geocells are very weak parts. Once the nodes fall off or deform, the application scope of the geocells will be affected. At the same time, for the geocells installed in the flexible retaining walls around the highway, they are directly exposed to the outside and warning signs cannot be installed, so they cannot play a warning role.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 2 As shown, the injection molded connector 100 consists of a connecting pipe 101 and a connecting cover 102, wherein the bottom of the connecting pipe 101 is configured to be in a pointed cone shape, which is conducive to inserting the connecting pipe 101 into the soil more effortlessly, and an anti-corrosion layer is provided on the outer side of the pointed cone. The material of the anti-corrosion layer can be selected from epoxy resin coating or polyurethane coating to improve the anti-corrosion ability of the connecting pipe 101 in the soil; an installation cavity is opened inward at the upper end of the connecting pipe 101, and the sheet 200 is arranged in this installation cavity; an internal thread is provided on the inner wall of the upper end of the installation cavity, and the connecting cover 102 is T-shaped, and an external thread matching the internal thread is provided on the outer wall of the lower end thereof.

At this time, the pressure sensor 405 will sense the pressure change of the movable plate 403 and transmit the signal to an external receiving device. The staff can understand the degree of deformation of the injection molded connector 100 through the receiving device, and can take precautions in advance to prevent the injection molded connector 100 from continuing to be deformed by force to a damaged state.
