Synchronous construction method for TPZ red core molecular level bonding waterproof coiled material

Abstract

The invention discloses a synchronous construction method for TPZ red core molecular level bonding waterproof coiled material. According to the synchronous construction method, TPZ red core molecular level bonding waterproof coiled material is constructed together with concrete/cement mortar base layer, wherein the method comprises following steps: base layer concrete construction; after 2-4 hours of the concrete construction, waterproof coiled material is wetly paved; after 24-48 hours of the wet paving of the waterproof coiled material, concrete protective layer construction is performed. The synchronous construction method is safer in water resistance, higher in construction efficiency, and simpler in waterproof structure arrangement.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a synchronous construction method of a TPZ red core molecule-adhesive waterproof coiled material. Background technique [0002] At present, the waterproof materials used for buildings, tunnels and garage roofs are mainly various waterproof rolls. Different waterproof membranes have different requirements for the base surface during construction. SBS, self-adhesive and other waterproof membranes, the waterproof construction base surface must be dry, flat, and reach the design strength of the base before construction; traditional wet-laid coils can be constructed on a wet base, but the waterproof base requires complete curing and reaches the design strength. The surface is flat and has strict requirements on the waterproof base. [0003] The following treatment should be carried out on the base layer before the waterproof construction of the wet-laid membrane: [0004] (1) Cleanin...

AI Technical Summary

Problems solved by technology

[0008] (1) The waterproof safety is poor, and there is a potential risk of leakage

[0009] ① Long-term deposition of silt on the waterproof base surface, concrete or cement mortar dropped and bonded to the base surface, and laitance on the concrete base surface are all very difficult to clean up, and it is difficult to meet the cleanliness requirements of the base layer required for wet-laying coils , resulting in delamination of the cement sealant used for the wet-laid coil material and the base layer after solidification, resulting in the failure of the seal between the wet-laid coil material and the base surface, and the risk of large-scale water leakage in the project

[0010] ②The smooth concrete or cement mortar waterproof base surface after complete curing makes the cement sealant material used for wet-laying coils easy to delaminate with the base layer after solidification, resulting in failure of sealing between wet-laying coils and the base surface, and major engineering accidents Risk of area channeling and water leakage

[0011] ③The base surface of dry concrete or cement mortar is difficult to wet to the saturated state of water content, and the wet-laid coils are paved with cement mortar. Because the cement mortar is very thin (thickness is about 1.5mm), it is easy to absorb water from the base layer. Cause the cement slurry to lose water and lose its strength, cause the wet laying seal to fail, and cause large-scale water leakage

[0012] ④ It is impossible to avoid the engineering leakage caused by forced waterproofing construction when the waterproof base layer cannot meet the waterproof construction conditions due to rushing the construction period and other reasons, resulting in waterproof defects

If the waterproof layer is damaged or defective, the open water infiltrated into the waterproof layer will spread along the mortar leveling layer and the channel between the structural layer and the channel, causing engineering leakage

[0015] (2) The waterproofing construction period is long and cannot cope with projects with a tight construction period

Although this method uses the method of wet laying, the waterproof construction of the coiled material is carried out after the base surface reaches the design strength and is dry, which seriously affects the safety of wet laying and sealing, and large-scale water leakage is prone to occur in waterproofing projects
