Problems solved by technology

Among them, the water-stop strip is used to seal the water by squeezing the concrete after absorbing water and swelling to block the gap. The cost is low, but there are many unforeseen problems in the construction process.
The water-stop belt has a good water-stop effect, but because the water-stop belt is a soft rubber product, it is easy to deform and not straight when pouring concrete
The water-stop steel plate has a good water-stop effect and is easy to install, but the cost is high, and the adaptability and strain capacity to construction joints with complex structures are poor

Abstract

The invention belongs to the technical field of waterproof construction methods, and particularly relates to a low-temperature-resistant zero-defect waterproof construction method for a building underground structure. The method comprises the following steps of carrying out base layer treatment before paving by using an anti-sticking coiled material of a strong cross laminated film; constructing a bottom plate; and performing waterproof construction on a side wall of the underground structure. The coiled material disclosed by the invention is flatly paved on a cushion layer and is firmly lapped, and the full sticky effect on the cushion layer is not required. After the structure on the macromolecular self-adhesive film waterproof coiled material of the cross laminated film to be lapped is constructed, the coiled material is reversely and tightly adhered to the bottom of a structural layer, so that the active waterproof effect is achieved. According to the method, the waterproof construction quality is guaranteed, the cross-flow risk of structure leakage is completely eradicated, the first-level waterproof requirement of waterproof construction is completely met, the method is not affected by the low-temperature environment, and the method can be popularized and applied to all underground construction projects in the whole industry.

Description

technical field [0001] The invention belongs to the technical field of waterproof construction methods, and in particular relates to a low-temperature-resistant zero-defect waterproof construction method for building underground structures. Background technique [0002] Construction joints refer to the joints formed between the first and last poured concrete due to design requirements or construction needs to be poured in sections during the concrete pouring process. The construction joint is not a real "seam". It is just because the concrete is poured first and exceeds the initial setting time, and there is a joint surface with the concrete poured later. The joint surface is called the construction joint, and the construction joint is waterproof. It is a difficult point in the waterproofing of the diaphragm wall and a key link in the self-waterproofing of the structure. If it is not handled properly, water leakage will easily occur. [0003] Commonly used water-stop materi...
