Partial pool wall reconstruction dry construction recyclable device under the pool full of water operating conditions

Abstract

The invention relates to a recyclable device for partial pool wall renovation and dry construction under the operating condition of the pool full of water. The arc-shaped steel box with the opening passes through the outer arc side of the bottom and throws and fills sand bags underwater and the rigid connecting rod at the top to stick to the pool wall underwater. The arc-shaped water-stop sheet is welded on the inner arc side of the bottom of the open arc-shaped steel box, combined with the underwater concrete pouring in the half-well space to form an effective water-stop with the bottom of the pool, and the inside and outside of the open arc-shaped steel box There are two large and small grooves, combined with the underwater concrete pouring between the large groove and the pool wall, and the inflatable strip airbag embedded in the small groove, to realize the effective water stop between the curved steel box and the pool wall. By pumping water in the half-well space, a half-well-shaped dry operation space is formed; after the dry operation in the half-well space is completed, the underwater concrete in the half-well space is excavated, and the outer arc side of the bottom is thrown and filled with sandbags for hoisting and removal, and the top can be removed. Pushing the jack embedded in the elongated rigid connecting rod makes the underwater concrete between the large groove at the extremity and the pool wall peel off from the pool wall, realizing the recovery of the device.

Description

technical field [0001] The invention relates to a recyclable device for dry operation construction, in particular to a recyclable device and a construction method for partial pool wall reconstruction dry operation construction under the operating condition of a pool full of water. Background technique [0002] With the changes in the operating environment, operating standards, and operating processes, some old pump houses or pools in operation need to be renovated or newly added structures and equipment, such as opening holes in the walls of some pools and adding water intake and drainage pipes. [0003] There are two main methods for the reconstruction of the local pool wall of conventional pools. One is to stop the operation, and the dry operation will be carried out after the pool is drained. The construction is convenient, and the safety and quality can be easily guaranteed. However, the coordination of the outage is difficult, and in most cases, the operation can only b...

AI Technical Summary

Problems solved by technology

One is to stop the operation, and the dry operation will be carried out after the pool is drained. The construction is convenient, and the safety and quality can be easily guaranteed. However, the coordination of the outage is difficult, and in most cases, the operation can only be stopped intermittently. Organizations place extremely high demands on

The second is underwater operations. The construction process is greatly affected by the operating water head and operating flow rate of the pool. The divers' underwater operations have high construction risks and can only be modified with simple procedures.
