Method for preventing basement bottom plate post-cast strip from leaking

Abstract

The invention relates to a method for preventing a basement bottom plate from leaking, in particular to a method for preventing a basement bottom plate post-cast strip from leaking. The method comprises the steps that construction joints on the two sides of the basement bottom plate post-cast strip are cleared up and washed out, and no impurities such as mud blocks and garbage exist; professional waterproof construction persons are arranged to block found water seepage points; according to the floor thickness, a PVC tube with the matched diameter is selected for serving as a drainage tube; a PVC semicircular tube is laid along the post-cast strip and the concrete joints on the two sides in an opening-downward manner, the end of the drainage tube is led to a drainage ditch or a water collection well, the other side of the drainage tube is blocked by waterproof concrete, and the two sides of the drainage tube are firmly fixed through waterproof mortar or fine aggregate concrete, and are prevented from deviating or being damaged; and a basement floor is cast. According to the method, the phenomena that seepage points are found secondarily, and the specific seepage portion is hard to find are overcome; and processing is convenient, the time is saved, the cost is low, and adverse effects are avoided.

Description

technical field [0001] The invention relates to a basement, in particular to a method for preventing basement floor leakage. Background technique [0002] As a temporary construction joint, the post-pouring belt of the basement floor needs to be poured after a period of time according to the design requirements to connect the whole structure. With the passage of time, it is easy to corrode and age, and there is a possibility of leakage, and once leakage occurs, it is easy to bulge the floor and affect the use. At the same time, it is difficult to find the leakage point, and the maintenance is troublesome and the cost is high. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a method for preventing the leakage of the post-cast belt of the basement floor. The invention avoids secondary discovery of leakage points, and it is difficult to find defects in specific leakage parts, and is convenient to handle, saves time...

[0002] The basement floor post-pouring belt is used as a temporary construction joint. The joint needs to be reserved for a period of time according to the design requirements and then poured to connect the entire structure. With the passage of time, it is easy to corrode and age, and there is a possibility of leakage, and once leakage occurs, it is easy to bulge the floor and affect the use. At the same time, it is difficult to find the leakage point, and the maintenance is troublesome and the cost is high.
