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

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] Such as figure 1 , the embodiment of the present invention proposes a waterproof structure for construction joints of underground construction joints, including a first wall 1, a second wall 2 and a construction joint 3 between them. The construction joint 3 is waterproofed by epoxy resin. The filling layer 4 has been filled and anti-blocked once. In actual work, in addition to epoxy resin, in order to make the filling more firm, heated asphalt can also...

The invention provides an underground building joint construction gap waterproof structure which comprises a first wall body, a second wall body and a construction gap between the first wall body andthe second wall body, a waterproof groove is formed in the upstream face of the construction gap, a waterproof assembly is arranged in the waterproof groove, and the waterproof assembly comprises a steel plate waterstop and a water swelling waterstop which are sequentially arranged from the construction gap to the upstream face; a waterproof coiled material and a post-poured concrete layer are arranged outside the first wall body and the second wall body and wrap the construction gap and the waterproof assembly. According to the invention, effective waterproof treatment is carried out on the construction gap on the construction site.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a waterproof structure for construction joints of underground building joints. 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 materials in the prior art are water-stop strips, water-stop strips...
