Pool plugging construction method Where is the pool easy to leak

The general building will build a large pool on the roof to facilitate secondary water supply or stop water emergency. If the pool is not done well during the construction, it is prone to seepage problems in later use. Where are these easily permeated areas? How to do the pool plugging ? Let's take a look with Xiaobian.

Construction method of plugging the pool: Leakage of construction joints and construction cold joints

1, leakage reasons

Leakage at construction joints and construction cold joints is a defect in construction. It may be caused by improper construction when the concrete is poured. This process will be carried out by pouring the concrete in two places. If the concrete is installed after the buried stop-stop is installed, the concrete is poured. If you do so, it is easy to get out of order, causing the water stop belt to be pulled apart, and the phenomenon of being pierced by the reinforcing steel bar, and leakage of the construction joint occurs.

Moreover, the volume of concrete is relatively large. If the vibration is not in place during the pouring process, it will cause some pockmarking, that is, it is not tight enough and has holes. If the concrete is not supplied at the time of pouring, the construction cold joint phenomenon will occur, resulting in poor water resistance and leakage.

2, plugging construction treatment

If leakage occurs at the construction joint of the pool, it is necessary to find the specific area of ​​the leakage water first, and then plug the holes, looseness and other problems of seepage. At this time, it is possible to open a groove along the crack first, then clean up the waste generated after the groove, and the pool needs to be cleaned to keep the tank fully moist.

Then you can choose to deep-scrape caulking material, or you can use plugging king to fill the tank body, these caulking materials have excellent adhesion with the slot. After finishing the filling, drills should be drilled, mainly for grouting. The spacing between the holes should preferably be about 30 cm. The grouting pipe with a length of 10 cm should be installed for grouting. Finally, the grouting nozzle can be plugged with plugging material.

Plugging of the pool construction method II: Leakage at the pull bolt hole

1, leakage reasons

In the construction of the pool, if the sealing bolt is not installed with a water stop ring, or the size of the water stop ring does not meet the requirements of the specification, or the water stop ring passes through the bolt hole, etc., before it is fully welded, it is surrounded by it. It is very easy to form a gap and water seepage occurs.

2, plugging construction treatment

For leakage leakage problems at the bolt holes, internal pressure grouting can be used to solve the problem. Epoxy resin can be selected as the internal pressure grouting material, first in the outer wall of the pool about 3cm above the screw hole, drilled with an electric drill, to obliquely coincide with the screw hole, for the leakage of the screw hole below the serious 3cm also drilled, and then Insert the grouting tube in the eye, press the epoxy resin into it, and finally smooth the outer wall.

Editor's summary: The above is about the construction of the plugging of the pool and the two areas that are easy to leak. I hope the sharing of the Xiaobian can help everyone. In general, the pool leakage includes a large area of ​​seepage, seepage of the construction joints, deformation The seepage of the joints and the seepage of water through the wall pipes are to be constructed according to the specific circumstances when the leakage is blocked.
