A static pressure prefabricated pool and its construction method

Abstract

The invention discloses a static pressure prefabricated assembly type water tank and a construction method thereof. The construction method comprises the following steps of: dividing a tank wall structure into lath-shaped precast blocks for processing and prefabrication; locating a construction site, and excavating a guide pressure relief hole; sequentially pressing the lath-shaped precast blocksof the tank wall into a soil layer by using a static pressure machine, and forming a tank wall prototype; excavating internal soil, and arranging a support; eliminating the soil at connecting positions of the precast blocks, carrying out steel bar abutting joint, and carrying out cast-in-place construction at the connecting positions; and casting a bottom plate in place, and removing the support.A static pressure technology is applied to the construction of the water tank structure, can greatly reduce the earth excavation and backfilling amount in the conventional water tank construction process, reduces the deformation and uneven settlement of surrounding buildings, is suitable for construction in a narrow space, reduces the requirements on a construction site, accelerates the construction of the water tank, and shortens the construction period; and by adopting the static pressure technology, the noise is low during the construction period, and the construction can be performed on sites with surrounding residential areas. Meanwhile, the static pressure technology can greatly improve the friction resistance of the side wall of the water tank, which is beneficial to the reduction of anti-floating cost.

Description

technical field [0001] The invention relates to a pool structure, in particular to a novel construction method for the pool structure. Background technique [0002] On the one hand, with the rapid development of economy and industry, thermal power plants, sewage treatment plants, etc. need to build a large number of pools; on the other hand, under the background of ecological civilization construction, many existing pools are in urgent need of environmental protection renovation or reconstruction. In the process of renovation, it is often faced with the requirement of rapid construction. However, the existing pool construction basically adopts a large excavation scheme, which has a long construction period and a large amount of earthwork excavation and backfilling, which is likely to cause deformation and uneven settlement of surrounding buildings, especially not It is suitable for construction in narrow spaces and has a large demand for technological innovation. At present...
