Embodiment Construction

[0019] like figure 1 Among them, a construction method for the side wall joint where the concrete inner embedded pipe leads out includes the following steps:

[0020] A. According to the design drawings and construction planning, clearly mark the pipe number and group number, etc., locate the embedded pipe 1 in the concrete, lead the embedded pipe 1 to the designated position at the side wall joint, and process the thread on the pipe mouth, use The iron wire and the pipe clip fixedly connect the pre-embedded pipe 1 with the steel bar;

[0021] B. Bind steel bars according to the design requirements, set up side wall formwork; and fix it with steel pipe fences and braces.

[0022] C. One end of the casing 2 is threadedly connected to the embedded pipe 1, and the other end of the casing 2 is blocked and protected, and it is closely attached to the side wall formwork 4; specifically, the embedded pipe 1 at the joint needs to be led out To the side wall, a casing 2 with a diamet...

Abstract

The invention relates to a method for leading pre-embedded pipes in concrete out of side wall joints, comprising the following steps: A, positioning a pipe pre-embedded in concrete; B, binding reinforcing steel bars of side walls according to the design requirements, and erecting a template of a side wall; C, connecting one end of a casing with the pre-embedded pipe, sealing the other end of the casing for protection, and clinging the other end of the casing to the template of the side wall; D, pouring concrete; and E, detaching the template of the side wall after the strength of the concrete reaches the mould stripping requirement, cleaning up the opening of the casing, connecting the casing with a pipe of same diameter, and leading out the casing. Due to the steps, the construction of leading the pre-embedded pipe in the concrete out of side wall joints is realized. Because the pre-embedded pipe in the concrete is connected with the casing through screw threads, the external sealing and internal unblocking of the pre-embedded pipe are ensured. After finishing pouring the concrete and stripping the mould, the pre-embedded casing is connected with the pipe of same diameter, and the pre-embedded casing is led out of the side wall joints without disposing holes on the template of the side wall, thus the template is kept complete, the cost is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a construction method for leading out a pre-embedded pipe in concrete, in particular to a construction method and device for connecting and pouring to a pre-embedded pipe in concrete. Background technique [0002] In hydropower concrete construction, cooling water pipes and grouting pipes need to be buried inside the concrete for temperature control of dam concrete and joint grouting, etc. Most of these pre-embedded pipes are iron pipes, and the nozzles need to be separated from the concrete side walls (or at the side wall of the corridor). In the past, when the pre-embedded pipe passed the side wall parting joint, it was necessary to make holes on the side wall formwork surface or partially adjust it to a wooden formwork construction, which would damage the formwork, increase the difficulty of formwork removal, and affect the construction period and construction quality. Contents of the invention [0003] The technical prob...
