Problems solved by technology
Although this method ensures the integrity of the coiled material, due to the frosted surface, the coiled material cannot be better attached to the side wall of the pipe gallery
[0005] Therefore, in order to solve the problem that the pre-laid anti-adhesive TPO waterproof membrane with a frosted surface is not close to the side wall of the bottom plate of the pipe gallery, a more effective waterproof membrane construction that can significantly improve the construction of the bottom plate of the comprehensive pipe gallery has been invented. A New Approach to Efficiency and Construction Quality

Embodiment Construction
[0033] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] Such as Figure 9 As shown, a construction method for pre-laying anti-adhesive TPO waterproof membrane on the floor of a pipe gallery, the specific steps are as follows:
[0035] (1) After the inspection of the groove at the bottom of the foundation pit of the pipe gallery is qualified, pour the cushion layer 1 of the bottom plate of the pipe gallery, and the cushion layer is made of C20 plain concrete with a thickness of 100mm;
[0036] (2) Lay additional layer 2 and 1.6mm thick pre-paved anti-adhesive TPO waterproof membrane 3, in which the width of the pre-paved anti-adhesive TPO waterproof membrane should be 650mm wider than the outermost edge of the side wall of the pipe gallery, and use The highest position of the rolled material is below the water stop bolt; the additional layer is 1.5m...

Abstract
The invention provides a construction method of a pipe gallery base plate pre-paved reverse bonding type TPO waterproof roll material. The construction method comprises the steps of pouring a pipe gallery base plate cushion layer; laying an additional layer, pre-paving the reverse bonding type TPO waterproof roll material, and reserving the roll material; constructing a waterproof roll material protection layer, and conducting temporary protection on the reserved roll material; binding pipe gallery base plate rebars, and mounting a galvanized water stop steel plate; overturning the reserved roll material upwards, and temporarily fixing the reserved roll material to adjacent the rebars; erecting a base plate side wall form board; tightly nailing the overturning waterproof roll material to the inner side of the form board; mounting a water stop bolt, and fixing the form board; pouring base plate concrete for formation; continuing to constructing a pipe gallery side wall and a top plate structure; laying a self-bonding type TPO waterproof roll material at the pipe gallery side wall and the top plate structure; and connecting the self-bonding type TPO waterproof roll material with thepre-paved reverse bonding type TPO waterproof roll material through hot gas welding. By means of the construction method, formation quality and construction efficiency of the pre-paved reverse bondingtype TPO waterproof roll material at a pipe gallery base plate are improved, and meanwhile, the construction process is simplified.
Description
technical field [0001] The invention belongs to the technical field of construction of waterproof coiled material at the bottom plate of a comprehensive pipe gallery, and in particular relates to a construction method for pre-laying anti-adhesive TPO waterproof coiled material on the bottom plate of a pipe gallery. Background technique [0002] When constructing the bottom plate of the underground comprehensive pipe gallery, the waterproof structure of the bottom plate must be done first, and the waterproof roll material usually used at the bottom plate is a pre-laid anti-adhesive TPO waterproof roll material. This waterproof roll material is in contact with the bottom plate concrete. One side is frosted, and the side used for later bonding with self-adhesive TPO waterproof membrane is smooth. [0003] When carrying out the construction of pre-laid anti-adhesive TPO waterproof membrane at the bottom of the underground comprehensive pipe gallery, one method is to first instal...
