Description

Basement waterproof construction method

Technical Field

The application relates to the technical field of waterproof construction of underground structures of buildings, in particular to a basement waterproof construction method.

Background

In order to improve the utilization rate of underground space, a basement is usually arranged at the bottom of a building, and the basement is usually located in a space below the ground. Due to the existence of underground water, the waterproof of the wall surface of the basement is a problem which needs to be solved in the construction process of the basement.

Through adopting above-mentioned technical scheme, waterproofing membrane can improve the water-proof effects in the outer wall outside for groundwater's discharge only can go on through the aqueduct, thereby has reduced groundwater and has deepened the inside probability of outer wall.

Alternatively, in S4, a swivel is fixed to the drain pipe and then the swivel is fixed to the end of the water pipe.

Through adopting above-mentioned technical scheme, rotary joint's setting can be better in the position of the in-process adjustment drain pipe of installation to make the position and the angle that set up of drain pipe accord with the design requirement. In addition, the rotary joint is fixed in a threaded connection mode, so that the installation and the disassembly between the drain pipe and the water guide pipe can be facilitated.

Optionally, in S4, a rubber pad is sleeved outside the water conduit, and then the rotary joint is sleeved outside the water conduit for fixation, and an end face of the rotary joint abuts against the rubber pad.

Through adopting above-mentioned technical scheme, the setting of rubber pad can improve the water-proof effects of aqueduct and outer wall hookup location to reduce the probability of groundwater from outer wall and aqueduct hookup location infiltration. Simultaneously, the setting of rubber pad can also improve rotary joint's joint strength, because rotary joint supports tightly on rubber pad to the restriction that goes on rotary joint's position better reduces the probability that rotary joint breaks away from because rotating in the later stage use.

Optionally, in S2, after the water conduit is inserted into the formwork, the two ends of the water conduit are limited on the corresponding formwork.

Through adopting above-mentioned technical scheme, with the both ends of aqueduct spacing in the template, the both ends that utilize the aqueduct in other words have carried on spacingly to the template to make the aqueduct possess the fixed effect to drawing the screw rod, improved the stability and the pouring quality of concrete placement in-process.

Alternatively, in S2, the inner pipe is inserted outside the water guide pipe after the release agent is sprayed on the outer wall of the inner pipe.

Through adopting above-mentioned technical scheme, at the in-process of concreting, partial concrete can be through the outer wall of the contact inner tube in the inlet hole, and the spraying of release agent can be convenient for later stage inner tube to take out from.

Optionally, in S1, the length of the inner tube is greater than that of the water conduit, and a limiting plate is fixed on the outer wall of the inner tube; the outer diameter of the inner pipe is consistent with the inner diameter of the water guide pipe, and when the inner pipe is inserted into the water guide pipe and the limiting plate is tightly abutted to the end part of the water guide pipe, the inner pipe can cover all water inlet holes in the water guide pipe.

Through adopting above-mentioned technical scheme, the external diameter of inner tube and the internal diameter of aqueduct are unanimous to make the inner tube insert the inside back of aqueduct, and the outer wall of inner tube and the inner wall of aqueduct are in and support tight state to the probability in clearance between concrete entering aqueduct inner wall and the inner tube outer wall through the income water hole has been reduced to the concrete in-process of building. And the setting of spacing board on the inner tube can be convenient for fix a position the position of inner tube in the work progress to make the inner tube construction cover the income water hole on the aqueduct, can be convenient for the later stage simultaneously and extract the inner tube.

In summary, the invention includes at least one of the following beneficial technical effects:

1. the water guide pipe is pre-buried in the construction process of the outer wall, and the water inlet hole is formed in the water guide pipe, so that underground water outside the outer wall and underground water penetrating into the inner part of the outer wall can be discharged through the water guide pipe, dredging replaces repairing, and the waterproof effect of the outer wall is improved;

2. the drainage effect can be improved through the arrangement of the drainage pipe;

3. the water guide pipe is used as the counter-pulling screw rod, so that the cost of materials in the construction process is reduced, the construction quality can be improved, and two purposes are achieved.
