Description

Technical Field

[0001] The utility model belongs to the technical field of earthwork engineering, and particularly relates to a self-locking extrusion snap-type sheet geocell connector. Background Technique

[0002] Earthwork engineering is one of the main types of work in construction engineering, including all aspects of excavation, filling, transportation of soil (rock), as well as drainage and dewatering. Earthwork engineering has a large amount of work, complex construction conditions, and is greatly affected by geological, hydrological, meteorological and other conditions. However, in actual engineering construction, earthwork engineering construction faces problems such as the sliding of the gravel cushion layer during laying, and the project being washed by rainwater. The processes are costly, laborious, and material-consuming, and it is difficult to guarantee the project quality. The use of geocells plays an important role in earthwork engineering. A geocell is a three-dimensional reticulated cell structure formed by welding high-strength HDPE sheet materials, generally welded by ultrasonic needle welding. Geocells can usually increase the anti-bending, tensile and shear strengths of the soil. Since the geocell has a certain height, it can play the role of a beam and has a moment of inertia and bending strength. Reinforcing the soil with geocells can play a role in resisting static loads, improve the bearing capacity of the soil, and reduce the settlement and displacement of the slope. Reinforcing the slope soil with geocells is an effective and convenient method and is widely used in engineering slopes such as highways and river channels. At the same time, the role of geocells in greening is mainly reflected in slope reinforcement and greening, preventing soil erosion and vegetation damage, and protecting the safe driving of the slope road.

[0003] Existing geocells usually connect the cell sheets by means of welding, riveting or injection molding connection. These connection methods have many processes, affect production efficiency, and the connection points are prone to breakage, with many potential safety hazards.

[0004] Therefore, it is necessary to provide a self-locking extrusion snap-type sheet geocell connector to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a self-locking extrusion snap-type sheet geocell connector to solve the problems existing in the above-mentioned prior art.

[0006] To achieve the above purpose, the utility model provides a self-locking extrusion snap-type sheet geocell connector, which includes a first clamping body and a second clamping body. A number of first locking teeth are arranged on the first clamping body, and a number of second locking teeth are arranged on the second clamping body. A first accommodating groove for accommodating the second locking teeth is formed on the first clamping body, and the first accommodating groove and the first locking teeth are arranged alternately. A number of second accommodating grooves for accommodating the first locking teeth are arranged on the second clamping body, and the second accommodating grooves are arranged corresponding to the first locking teeth. The second locking teeth and the first locking teeth are engaged with each other.

[0007] Preferably, both the first engaging body and the second engaging body are semi-cylinders, and the first engaging body and the second engaging body form a cylinder.

[0008] Preferably, the first locking tooth includes a first connecting plate vertically and fixedly connected to the rectangular surface of the first engaging body. On the opposite sides of two adjacent first connecting plates, a first wedge block is fixedly connected respectively, and the second locking tooth is clamped with the first engaging body through the first wedge block.

[0009] Preferably, the second locking tooth includes a second connecting plate vertically and fixedly connected to the rectangular surface of the second engaging body. On the upper and lower sides of the second connecting plate, a second wedge block is fixedly connected respectively, and the second wedge block abuts against the first wedge block.

[0010] Preferably, the cross-section of the first connecting plate is a semi-circular structure.

[0011] Preferably, the cross-section of the second connecting plate is a semi-circular structure.

[0012] Preferably, at both ends of the second engaging body, clamping plates are fixedly connected in parallel. At both ends of the first engaging body, clamping grooves are formed, and the clamping grooves are adapted to the clamping plates.

[0013] Compared with the prior art, the utility model has the following advantages and technical effects:

[0014] The self-locking extrusion snap-type sheet geomembrane connector provided by the utility model cancels the shear pin member of the traditional locking member, reduces the process of installing the shear pin into the gap between two members, and only needs to squeeze the first engaging body and the second engaging body to complete the installation, which greatly reduces the time for installing the members, improves the efficiency of connecting the sheets, saves time costs and reduces expenses.

[0015] Through the mutual engagement and clamping of the first locking tooth and the second locking tooth, there is no need to worry about the problem of falling off after installation, which further improves the installation reliability and safety.
