Problems solved by technology

This method: the installation of hidden beams and hidden columns requires a large opening in the old pool, which increases the amount of work, which is not conducive to the anti-seepage and leakage prevention of the side walls; Water leakage and seepage at the opening after the hole is opened cannot fully meet the safety standard for leak prevention

Embodiment 1

[0028] In a large-scale steel factory wastewater recycling advanced treatment project, in order to reduce engineering investment, the old pool needs to be used for renovation. It is necessary to open a hole in the side wall of the old pool. The inner diameter of the tube 6 is 200 mm). First, the construction workers drilled a hole in the side wall of the old pool, and the radius of the hole was 70 mm larger than the radius of the steel waterproof casing 6 . Cut out the concrete on the pool wall at both ends of the hole, so that the two ends of the hole are ring-shaped, and leak out the steel bar 5 in the pool wall, and the leakage length of the steel bar 5 in the pool wall is 180mm. Then chisel out two V-shaped ring grooves 2 on the hole inwall. Then insert the steel waterproof casing 6 with the water stop ring 7 into the hole, weld the L-shaped steel bars 3 to the steel bars 5 in the pool wall and the steel waterproof casing 6 respectively, and connect the steel waterproof c...

Abstract

The invention discloses a construction method and structure of holing, reinforcing and leaking preventing of an old pool side wall. The structure comprises L-shaped reinforcing steel bars, a steel waterproof casing pipe and a micro expansion secondary grouting material layer, the steel waterproof casing pipe and the L-shaped reinforcing steel bars are welded and fixed, the L-shaped reinforcing steel bars are welded and fixed to reinforcing steel bars in the pool wall, the position between the steel waterproof casing pipe and concrete of a hole of the pool wall is filled with the micro expansion secondary grouting material layer, a V ring groove is formed in the inner wall of the concrete of the hole of the pool wall, and the micro expansion secondary grouting material layer is embedded inthe V ring groove. Compared with the traditional construction method, the method has the advantages of being small in holing, convenient to reinforce, small in work amount, capable of reducing the work amount by more than 80%, capable of enabling the leakage prevention and seepage prevention rate to be increased by 90%, and capable of achieving the aims of preventing leakage and seepage and prolonging the service life.

Description

technical field [0001] The invention relates to the field of industrial construction, in particular to a construction method and structure for opening holes in the side wall of an old pool to reinforce and prevent leakage. Background technique [0002] In industrial buildings, if the old ordinary pools, acidic pools, alkaline pools, oil pools, etc. need to be improved in process and holes are leaked, it is necessary to add holes in the side walls of the built pools to connect pipelines. The traditional method is to set up hidden beams and columns at the opening of the hole for reinforcement after opening the side wall of the pool. Set up the waterproof casing, and lay the waterproof layer on the inner wall of the pool. This method: the installation of hidden beams and hidden columns requires a large opening in the old pool, which increases the amount of work, which is not conducive to the anti-seepage and leakage prevention of the side walls; Leakage and water seepage at t...
