High-strength geocell

Abstract

The invention discloses a high-strength geocell which comprises steel bars and plug-in elements, wherein an open slot is correspondingly formed in the junction of adjacent steel bars, the free ends of the plug-in elements respectively pass through the open slots on the two steel bars in sequence in a staggered manner to connect and weave the two steel bars together, and seal locking elements for preventing plug-in elements from coming out are connected with the free ends of the plug-in elements. The seal locking elements arranged on the plug-in elements can effectively prevent the plug-in elements from coming out during the fabrication, transportation and use processes of the geocell, so as to ensure the normal use of the geocell.

Description

technical field [0001] The invention relates to a geocell. Background technique [0002] Geocells are made of sheets made of polymer materials. Through technological means, a three-dimensional grid cell space is formed. It can be expanded and contracted freely. It constitutes a structure with strong lateral restraint force and high rigidity. It is generally used in engineering fields such as strengthening the roadbed of railways and highways, protecting slopes of airports and ports, and building retaining walls. [0003] At present, there are the following types of geocells: [0004] 1. The plastic sheet strips are formed by extrusion and calendering without stretching, and are welded by ultrasonic welding. The joint strength is only 200N / cm, which is easy to crack and cause project failure. [0005] 2. After stretching the plastic sheet strips, the joints are riveted with rivets. Although the tensile strength of the sheet is improved, the strength of the joints still can...

AI Technical Summary

Problems solved by technology

[0004] 1. The plastic sheet strips are formed by extrusion and calendering, without stretching, and are welded by ultrasonic welding. The joint strength is only 200N / cm, which is easy to crack and cause project failure.

[0005] 2. After stretching the plastic sheet strips, the joints are riveted with rivets. Although the tensile strength of the sheet is improved, the strength of the joints still cannot reach the tensile strength of the sheet, so the joints are still weak links

[0006] 3. The plastic sheet strips are formed by extrusion and calendering without stretching, and are connected by punching with a single plug-in. In this way, the molecular arrangement has no orientation because the sheet is not stretched. , if the hole is punched, the strip will be damaged, and the hole will be brittle

However, in the actual production and use process, the following defects of the above-mentioned geocells are also exposed: 1. During the production process, the installed plug-ins are misplaced, loosened, and fall off due to frequent changes in operating positions between processes.

2. In the process of product handling, loading, unloading, and transportation, the plug-in is also prone to slipping and falling off

[0008] The defect that the above-mentioned plug-ins are easy to fall off has caused great troubles to the production and use of the product, and has caused great hidden dangers to the quality of the project.
