Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] In the description of the present invention, the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", " The orientations or positional relationships indicated by "top", "bottom", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not indicative or implied. It should not be construed as limiting the invention that a device or element must have a particular orientation, be constructed, and operate in a particular orientation.

[0024] Such as Figure 1~2 As shown, the present invention provides a kind of caisson construction method of sewage treatmen...

Abstract

The invention discloses a sewage treatment sinking well construction method. A sinking well is rectangular, and the method comprises following steps: firstly, two rings of jet grouting piles which are in lap joint are arranged at the 3 to 4m position of the outer wall of the sinking well, a water stop curtain wall is formed, and the lower ends of the jet grouting piles exceed the bottom seal face by 2 to 3 m; pulling-resisting piles are constructed on the periphery of a foundation pit, foundation pit digging is carried out, the sinking well is manufactured, sinking well sinking is repeatedly carried out until the sinking wheel sinks to the reserved position, bottom seal is carried out, and the gap between the foundation pit and the sinking well is filled. Water inlet pump room basic construction is carried out according to the sludge layer geological conditions, and the working period can be shortened.

Description

technical field [0001] The invention relates to the field of building foundations. More specifically, the present invention relates to a caisson construction method for sewage treatment. Background technique [0002] The caisson is a technology used in the construction of deep foundations and underground structures. Its principle is: on the ground or in the pit, first make a reinforced concrete well chamber with an opening, and after the concrete in the well chamber reaches a certain strength, dig soil in the well. The soil body is gradually lowered, and the caisson well chamber relies on its own weight to overcome the frictional resistance between it and the soil wall, and sinks continuously until it reaches the design elevation, and then the bottom sealing process is carried out after in-position correction. [0003] At present, my country's rapid economic development has also brought more and more pressure on the social environment. As people's awareness of environmental...
