Guiding device for preventing rainwater leakage of external wall casing pipe of basement and construction method thereof

Abstract

The invention discloses a guiding device for preventing rainwater leakage of an external wall casing pipe of a basement and a construction method thereof. The guiding device comprises a tube well; thebottom of the tube well is sealed; the tube well communicates with the external wall casing pipe of the basement by a first through hole formed in the lower portion of the tube well; the tube well communicates with a drain pipe by a second through hole formed in the lower portion of the tube well; the drain pipe communicates with an outer net drainage pipeline; and the height of the second through hole is lower than the height of the first through hole. The construction method comprises the steps that a bed course is poured, and the bottom ground of the tube well is subjected to slope finding; the tube well is constructed, and the first through hole and the second through hole are reserved at the lower portion of the tube well; and the external wall casing pipe of the basement is connected with the first through hole, one end of the drain pipe is connected with the second through hole, and the other end of the drain pipe is connected with the outer net drainage pipeline. The guiding device can effectively guide rainwater and sewage which seep to the underground to the outer net drainage pipeline, so that the basement is free from rain infiltration, and articles in the basement areprevented from being dampened or soaked. According to the construction method, materials can be obtained easily, manufacturing is easy, and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to a diversion device and a construction method for blocking rainwater seepage from casing pipes of an outdoor wall of a basement. Background technique [0002] In construction and installation projects, it is often necessary to pass some pipes and cables out of the building wall. In order to protect the pipes and cables from being damaged by the pressure of the wall, wall bushings are often installed on the wall to connect the pipes and cables Pass through the casing. During the installation process of the basement building, the outer wall casing of the basement is generally laid after the pipe or cable is laid, and the mouth of the pipe is sealed with hemp silk and sealing material, and then buried with soil. [0003] However, in practice, it has been found that after a long period of rainwater soaking at the casing port of the outer wall, water...
