Embedded-free casing pipe mounting structure and casing pipe mounting method

Abstract

The invention relates to an embedded-free casing pipe mounting structure and a casing pipe mounting method. The mounting structure comprises a reamer bit and two hole sealing templates, wherein the reamer bit comprises a flat bit section, a reaming section and a connecting pipe; the reaming section is in a circular truncated cone shape and is connected to the flat bit section through the upper end surface of the reaming section; the connecting pipe is concentrically connected to the lower end surface of the reaming section; each hole sealing template comprises a cylindrical fastening ring, a hole sealing ring mounted on the fastening ring and a feeding port formed in the hole sealing ring; and the hole sealing templates can be mounted on a water stop casing pipe through the fastening rings. According to the embedded-free casing pipe mounting structure and the casing pipe mounting method, a horn-shaped water stop wing ring of the water stop casing pipe is implanted into a concrete structure, so that the path of water and air on the upstream face of the structure flowing into the downstream face is increased.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a casing installation structure without pre-embedding and a casing installation method. Background technique [0002] At present, in the construction of infrastructure projects, there are high watertightness and airtightness requirements for the basement exterior wall and roof of the concrete structure, the civil air defense area, and the pollution prevention area of ​​the hospital. However, in the actual construction process of the water-stop casing, it is often found that it is difficult to seal the concrete around the circular casing of the water-stop casing. Concrete is not dense, seepage phenomenon. [0003] At the same time, due to design changes, construction negligence, etc., it is often caused that the pre-buried water-stop casing is forgotten or the hole needs to be re-drilled due to unreasonable location, and the use of ordinary casing in the re-drilled ...

[0002] At present, in the construction of infrastructure projects, there are high watertightness and airtightness requirements for the basement exterior wall and roof of the concrete structure, the civil air defense area, and the pollution prevention area of ​​the hospital. However, in the actual construction process of the water-stop casing, it is often found that it is difficult to seal the concrete around the circular casing of the water-stop casing. Concrete is not dense, seepage phenomenon

[0003] At the same time, due to design changes, construction negligence, etc., it is often caused that the pre-buried water-stop casing is forgotten or the hole needs to be re-drilled due to unreasonable location, and the use of ordinary casing in the re-drilled place will generally cause water and gas leakage. point of
