A blind ditch production equipment and process

Abstract

The invention relates to blind ditch production equipment and technology. The blind ditch production equipment comprises a heat sealing machine, an edge cutting machine, a film laminating machine, anda heat recessing machine which are sequentially arranged, wherein the heat sealing machine is used for combining a plastic mesh with geotechnical cloth together to form a composite layer; the edge cutting machine is used for cutting the composite layer; the film laminating machine is used for applying the composite layer onto the surface of a bland ditch; the heat recessing machine is used for forming slots in two ends of the bland ditch, and comprises an operation platform, a blind ditch mounting support, a recessing device, and a back-and-forth movement driving mechanism of the recessing device, wherein the recessing device comprises a moving platform and two heating sheave wheels which are symmetrically arranged at the left end and the right end of the moving platform; and electric heating devices are respectively arranged in the heating sheave wheels. Compared with the prior art, the blind ditch production equipment disclosed by the invention has the advantages that the compositelayer is firmly bonded to the surface of the blind ditch, so that the phenomenon that the composite layer falls off is avoided; and the integral structural strength of the blind ditch is enhanced, sothat the blind ditch cannot be damaged under higher pressure.

Description

technical field [0001] The invention relates to the technical field of blind ditch production, in particular to a blind ditch production equipment and process. Background technique [0002] The blind ditch is a kind of underground drainage channel, which is used to drain groundwater and lower the groundwater level. With the continuous development of blind ditch technology, plastic blind ditch has been widely used. [0003] The plastic blind ditch is made of thermoplastic synthetic resin as the main raw material. After modification, in the hot melt state, the thin plastic filaments are extruded through the nozzle, and then the extruded plastic filaments are welded on the nodes by the molding device. , forming a three-dimensional network structure. In practical application, the blind ditch has problems such as low strength, easy damage under high pressure, and easy blockage of blind ditch by sediment during use. In order to solve the above problems, a method of wrapping geote...

AI Technical Summary

Problems solved by technology

In practical application, the blind ditch has problems such as low strength, easy damage under high pressure, and easy blockage of blind ditch by sediment during use. In order to solve the above problems, a method of wrapping geotextile on the surface of the blind ditch appeared. The geotextile is compounded on the outside of the blind ditch body by adhesive

The blind ditch with this structure has the following defects during use: ① It is necessary to manually apply the adhesive on the surface of the blind ditch, the efficiency of manual application is low, and the application is uneven, and the geotextile often falls off from the surface of the blind ditch during use. ② During use, it was found that wrapping the geotextile on the surface of the blind ditch can only play a role in isolating sediment, and the overall structural strength of the blind ditch has not been improved, and it will still be damaged under high pressure; ③ The structural strength of the geotextile Low, and in direct contact with the covered sand and stones during use, the geotextile is prone to wear and tear, which reduces the effect of the geotextile in insulating sand; ④

[0004] The blind ditch connection is to connect two adjacent blind ditches together by embedding a staple-like nail hook. This connection method is time-consuming and laborious, and the connection is poor in firmness and easy to fall off.
