Seepage prevention structure and method for periphery of floor-passing-through pipeline

Abstract

The invention discloses a seepage prevention structure and method for a periphery of a floor-passing-through pipeline. The seepage prevention structure for the periphery of the floor-passing-through pipeline comprises a concrete floor, the floor-passing-through pipeline, and a special hole plugging template, wherein a reserved hole is formed in the concrete floor; the floor-passing-through pipeline passes through the reserved hole of the concrete floor and is positioned in the middle of the reserved hole of the concrete floor; the special hole plugging template is clamped on the floor-passing-through pipeline and positioned on the bottom surface of the concrete floor; the seepage prevention structure further comprises a water swelling strip; the water swelling strip is wound on the periphery of the floor-passing-through pipeline and positioned at 1 / 2 of the floor thickness of the concrete floor. According to the invention, the adopted water swelling strip has a water swelling function, is arranged in a concrete joint, where water prevention is required, and swells fast gradually with the passage of time, and a concrete joint can have a sealing water stopping effect after being subjected to swelling pressure of the water swelling strip, so that when the seepage prevention structure is used for periphery seepage prevention of the floor-passing-through pipeline and a pipeline sleeve, a better effect is achieved.

Description

[0001] technical field [0002] The invention relates to an anti-seepage structure and an anti-seepage method around a pipeline passing through a floor slab. Background technique [0003] In order to solve the leakage problem around the pipeline of the building, many measures have been taken in the design and construction. Some measures focus on the detailed structure, but due to the complicated process and difficult operation, the construction effect is difficult to achieve the expected effect; some measures are in the Adding an additional waterproof layer around the pipe, adding a mortar waterproof ring, etc., can improve the waterproof effect, but because the waterproof material needs to be turned up and wrapped around the pipe to be exposed, it will affect the visual effect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an anti-seepage structure around the pipeline passing through the floor. [0005] Anoth...
