Waterproof structure for bottom wall plate and post-cast strip of basement and construction method thereof

Abstract

A basement bottom wall panel post-casting strip waterproof structure and its construction method, comprising a bottom wall panel (1) and a post-casting strip (2), characterized in that: the side wall of the bottom wall panel (1) and the post-casting strip The joint part of (2) is provided with a concave seam (3), and the middle part of the concave seam (3) is inlaid with a waterproof steel plate (4), and the foundation cushion (5) is located at the bottom of the post-casting belt (2) A water collection tank (6) is provided, and the bottom of the water collection tank (6) is horizontally fixed with a water collection semicircular pipe (7). One or more waterproof layers are arranged between the cushion (11) and the lower concrete cushion (12). The present invention adopts multiple waterproof designs, which improves the waterproof performance and has better adaptability to poor building settlement. It effectively integrates water blocking and drainage, and solves the long-standing technical problem of different degrees of leakage in the post-casting belt of the basement.

Description

technical field [0001] The invention relates to a post-cast tape waterproof structure and a construction method thereof, in particular to a basement bottom wall board post-cast tape waterproof structure and a construction method thereof, belonging to the technical field of building waterproofing. Background technique [0002] With the rapid development of the economy, the scale of urban construction is expanding day by day, the area of ​​the basement is getting bigger and bigger, and the depth is getting deeper and deeper, so that the waterproof performance of the basement bottom wall plate post-casting belt is also put forward higher requirements. In the structural construction of large basements, it is generally necessary to set up post-pouring belts to solve the problems of poor settlement and reduce shrinkage stress. The structural design and construction technology of post-pouring belts will affect the quality of the entire basement. And water-stop performance also dire...

AI Technical Summary

Problems solved by technology

[0003] The first purpose of the present invention is to address the disadvantages of existing basement post-cast belts with simple structure, generally only one or more waterproof layers are provided on the concrete surface or inside, the waterproof performance is poor, and water leakage and water seepage are prone to occur and deficiencies, now provide a reasonable structure, the use of multiple waterproof design, waterproof performance has been improved, and has a good adaptability to poor building settlement, even if there is a local leakage, water can also be unobstructed dredging discharge, no need It will have adverse effects on the building structure and daily use, and the service life has been extended. A basement bottom wall plate post-cast waterproof structure

[0004] The second purpose of the present invention is to aim at the simple construction method of the existing basement post-pouring belt, which only has a short-term waterproof effect, does not have good adaptability to building settlement differences, and always has different degrees of damage after using it for a long time. Leakage, defects and shortcomings of short service life, now provide a short construction period, better adaptability to building settlement difference, waterproof performance has been improved, the multiple waterproof design adopted effectively avoids leakage, service life A long construction method of post-cast waterproof structure of basement bottom wall slab
