Embodiment Construction

[0060] This embodiment will be described in detail in conjunction with an engineering example. The length*width*height of the AAO reaction pool in a water purification and sewage treatment plant project undertaken by Sinochem Second Construction Group Co., Ltd. is 84.8m*67.5m*6.6m, with a design capacity of 30,000 cubic meters and a maximum capacity of about 36,000 cubic meters. It is a unit combined reinforced concrete sewage tank. The whole pool is divided into 9 independent plate units by four longitudinal and transverse deformation joints, such as the pool bottom plate, wall plate, inner partition wall, upper diversion channel, and 30mm wide deformation joints are set between adjacent plate units. , The deformation joint relies on the buried rubber waterstop to connect 9 independent plate units to form a whole, and the waterproof and water stop at the deformation joint is completely guaranteed by the buried rubber waterstop. The pool wall is a special-shaped variable sect...

Abstract

The invention relates to a unit combined type cesspit structure construction method. The unit combined type cesspit structure construction method comprises the steps of earth excavation, foundation treatment, cushion construction, bottom plate construction and pool wall construction. A bottom plate and pool walls are each divided into a plurality of unit plates, and construction is carried out ina spaced symmetry manner. Expansion joints are arranged between the plates, concrete structures on the expansion joints are completely disconnected, and a pool is connected into a whole only through an intermediately buried type rubber waterstop. An optimized heat vulcanization welding method is adopted, the rubber waterstop is mounted and fixed on site, the construction quality of the intermediately buried type rubber waterstop is ensured, and major quality accidents are avoided. The construction technology process is overall optimized, so that the construction quality of the rubber waterstopis guaranteed, the construction process can be accelerated, and the construction period can be shortened.

Description

technical field [0001] The invention relates to a construction method for a sewage pool structure, in particular to a self-waterproof clear-water concrete construction method for a large-scale, complex-structured unit combined sewage pool structure. Background technique [0002] With the continuous development of the economy and the continuous improvement of the living standard of the residents, the problem of water pollution has been paid more and more attention by people. In recent years, the total amount of wastewater discharge in my country has been on the rise, and the demand for sewage treatment has continued to increase. The large-scale unit combined sewage pool is the core device of the sewage treatment plant at present. It has a large capacity and a complex structure. , the construction quality is difficult to control, and major quality accidents are prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is...
