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
The present invention relates to basement, particularly relate to a kind of method of preventing basement bottom board seepage.
Background technology
Basement bottom plate rear pouring tape stitches as a kind of temporary construction, this seam is built after need retaining a period of time according to designing requirement again, total is linked to be entirety, but the steel plate for sealing water adopted due to ater-casting or rubber fastening band are along with the passing of service time, perishable, aging, have the possibility that seepage occurs, and once there is seepage easily heave terrace impact use, be difficult to find breakthrough, maintenance trouble, and cost is high simultaneously.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of method of preventing basement bottom plate rear pouring tape seepage.Present invention, avoiding secondary and find breakthrough, be difficult to the defect finding concrete seepage place, easy to deal with, save time, cost is low, and has no adverse effects.
In order to solve the problems of the technologies described above, a kind of method of preventing basement bottom plate rear pouring tape seepage of the present invention, it comprises:
Step one, rinses well the cleaning of basement bottom plate rear pouring tape both sides constuction joint, must not have the foreign material such as clod, rubbish;
Step 2, arranges professional waterproof construction personnel by complete for the seepage point shutoff found;
Step 3, selects the pvc pipe of a diameter matches as drainage tube according to terrace thickness, and namely with after longitudinally being cut from middle part, it is the diameter that principle selects pipe that PVC semi-circular tube upper surface is no less than 2cm apart from terrace surface;
Step 4, described PVC semi-circular tube is laid along ater-casting and both sides concrete seam in the mode that Open Side Down, and the termination of drainage tube is caused gutter or collecting well, opposite side waterproof concrete is blocked, drainage tube both sides waterproofing mortar or pea gravel concreten fixation, prevent its off normal or destruction;
Step 5, builds basement terrace.
The present invention is before building basement terrace, along the pre-buried semicircle PVC drainage tube of the concrete seam crossing in ater-casting and both sides, drainage tube covers between two parties on gap, after terrace has been built, gutter or collecting well will be flowed to along drainage tube at the water of seam crossing seepage, avoid percolating water play back and forth in the interlayer of structure base slab and terrace, heave terrace or penetrate into terrace surface along terrace self gap after the comparatively large and hydraulic pressure of leakage exceedes certain pressure, destroy basement terrace and using function.
The present invention has the features such as execute-in-place is simple, applicability is strong, material price is cheap; Adopt the method can overcome ater-casting opposing sedimentation and deformation ability weak, steel plate water stopper and rubber fastening band perishable aging, after certain life cycle, easily there is seepage, destroy terrace, cause basement ponding and impact to use.This technique avoids secondary and find breakthrough, be difficult to find concrete seepage place, deal with take a lot of work, time-consuming, costly, destructive large and affect the shortcomings such as using function.
Detailed description of the invention
A kind of method of preventing basement bottom plate rear pouring tape seepage of the present invention, it comprises:
First constuction joint cleaning in basement bottom plate rear pouring tape both sides is rinsed well, the foreign material such as clod, rubbish must not be had;
Arrange professional waterproof construction personnel by complete for the seepage point shutoff found;
Select the diameter of drainage tube according to terrace thickness, longitudinally cut later half pipe upper surface from middle part and be no less than apart from terrace surface the diameter that 2cm is principle selection pipe;
Laid along ater-casting and both sides concrete seam in the mode that Open Side Down by semicircle PVC drainage tube, and the termination of drainage tube is caused gutter or collecting well, opposite side waterproof concrete is blocked, stifled tight a little;
In the process of laying drainage tube, in drainage tube both sides waterproofing mortar or pea gravel concreten fixation, its off normal or destruction to be prevented.
Build basement terrace.
