Structure suitable for existing pool wall later-embedded casing pipe and construction method

Abstract

The invention provides a structure suitable for an existing pool wall later-embedded casing pipe. The structure comprises a waterproof casing pipe (1), an embedded annular steel plate (3), added stirrups (8) and annular added reinforcing steel bars (9). The added stirrups(8), the annular added reinforcing steel bars (9), the waterproof casing pipe (1) and the embedded annular steel plate (3) are fixed to the pool wall, the added stirrups(8) and the annular added reinforcing steel bar (9) are connected, and the waterproof casing pipe (1) and the embedded annular steel plate (3) are connected. Compared with the manner of conventional single steel reinforcing rib adding for reinforcing, the composite reinforcing manner of a steel plate with anchor ribs and the added reinforcing steel bars enables the structure safety to be obviously improved, and the bearing mode is reasonable. A common template is difficult to erect, the concrete construction quality is poor, during pouring, the casing pipe is moved and staggered, the gas cutting end of a split waterstop bolt is prone to water seepage, the steel plate with the anchor ribs is convenient to mount, the steel template is suitable for thepost-pouring special-shaped area, the steel template and the circumference of the casing pipe are welded, and fixing of the casing pipe is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a structure and a construction method suitable for buried casing behind existing pool walls. Background technique [0002] At present, during the construction of structures in traditional above-ground sewage plants and underground (sinking) sewage treatment plant projects, a large number of pre-embedded casings will be carried out on the walls of reinforced concrete pools. The conventional design and construction is to embed the casing first and then pour the concrete in place, which can relatively guarantee the integrity of this area. However, sometimes the replacement of equipment or the adjustment of the process will lead to the increase or decrease of the casing or the change of the position. If the construction of the pool wall of the structure is completed at this time, it is necessary to open a hole and bury the casing later. Traditionally, as disclosed in the pa...
