Abstract

The invention discloses a wet placement method construction technique for macromolecule self-adhesive waterproof coiled materials. The wet placement method construction technique for the macromolecule self-adhesive waterproof coiled materials comprises the following steps of S1 cardinal plane cleaning and wetting and S2 coiled materials placing. The S2 step further comprises the steps of laying a first coiled material, laying a second coiled material and laying the remaining materials. The overlap joint edges of the coil materials are adhered by the coiled material bodies, so that an integral flexible waterproof effect is achieved; the problems of cracking, water leakage and freeze-thaw damage in cold regions of the overlap edges of the coiled materials caused by structural deformation and splits due to the traditional method of complete rigid overlap are solved; the reliability and durability of a waterproof layer are improved and the risk of leakage is reduced. Material selection and the material ratio of an adhesion sizing agent are specified; the problems of low intensity of an adhesion agent, pulverization of the adhesion agent and bulging and falling off of the coiled materials are solved; an upper surface membrane tectoria treatment technique is adopted in the process of sizing mucosa overlapping of the short edges of the self-adhesive coiled materials, so that the adhesion strength and durability of the upper surface membrane tectoria of the coiled materials and a self-adhesion sizing material are improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a wet-laying construction process of a polymer self-adhesive waterproof coiled material. Background technique [0002] At present, polymer self-adhesive waterproofing membranes are gradually being used in the waterproofing market, but there has been no standardized construction process, and the leakage rate remains high, resulting in good materials not being fully recognized by the market. [0003] When the waterproof construction teams of many manufacturers carry out the wet laying method of polymer self-adhesive waterproof membranes, the membranes and the membranes, the membranes and the base surface are all bonded with plain cement slurry, and the flexible waterproof material is bonded at the lap edge. Rigid waterproofing effect, especially in underground waterproofing projects, the dynamic load generated by personnel during the construction of the waterproof p...
