Modified asphalt waterproof coiled material for roads and bridges

Abstract

The invention discloses a modified asphalt waterproof coiled material for roads and bridges, and belongs to the technical field of asphalt waterproof coiled materials. A modified asphalt waterproof coiled material for roads and bridges comprises a shell and a coiled material composite cloth body, a fixing rod is arranged in the middle of the shell, a baffle is arranged at the left end of the shell, two inserting grooves are symmetrically formed in one end of the baffle, two inserting blocks are arranged at the left end of the shell, two bolts are symmetrically arranged at the upper end of the baffle, a spring A is arranged at one end of the baffle, and a push plate is arranged at the tail end of the spring A; a sliding groove A is formed in the front end of the shell, a sliding block A is arranged in the sliding groove A, a fixing plate is arranged at the front end of the sliding block A, a fire gun is arranged on the lower side of the fixing plate, a motor is embedded in one end in the sliding groove A, and a reciprocating threaded rod is arranged at the tail end of the motor. According to the device, when the motor and the reciprocating threaded rod rotate, the sliding block A can move in a reciprocating mode, so that the flame gun moves uniformly, the lower layer of the coiled material composite cloth body is burnt and heated automatically, and the burning uniformity is guaranteed.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coiled material, in particular to a modified asphalt waterproof coiled material for roads and bridges. Background technique [0002] Bitumen waterproofing membranes are used for waterproofing in roads and bridges. The patent document of CN211165657U disclosed in the prior art provides a modified asphalt waterproof coiled material for road and bridge. The coiled material can extrude the coiled material composite cloth by setting a pressing plate, so that the coiled material composite cloth is bonded to the road surface. [0003] Although the coiled material has many beneficial effects, the following problems still exist: When the staff is laying the coiled material composite cloth, it is necessary to use a gun to heat the geomembrane on the lower layer of the coiled material composite cloth to melt it and combine with the coiled material composite cloth. The surface of the body is paste...

AI Technical Summary

Problems solved by technology

[0003] Although the coiled material has many beneficial effects, the following problems still exist: When the staff is laying the coiled material composite cloth, it is necessary to use a gun to heat the geomembrane on the lower layer of the coiled material composite cloth to melt it and combine with the coiled material composite cloth. The surface of the body is pasted together, but it is difficult for the staff to heat the geomembrane evenly during the burning process. If the heating time is too long, the geomembrane will be burned through. If the heating time is too short, the geomembrane will not melt enough and affect the bonding effect.
