Embodiment 1

[0035] like figure 1 As shown, a construction method for temporarily skipping a sewage well according to an embodiment of the present invention includes the following steps:

[0036] S1: First, the staff will investigate the flow direction of the sewage according to the current situation, and at the same time determine the plan and the distribution map of the underground pipeline to release the well position of the jump discharge well. When the inclination is not more than 1%, a steel casing is buried. The inner diameter of the casing is 20cm larger than the diameter of the pile. The top surface of the cylinder is 20-30cm higher than the construction ground;

[0037] S2: When a positive circulation drilling rig is used, the geological profile is drawn according to the geological and hydrological data provided by the construction design, and different drill bits, drilling pressure, drilling speed and appropriate mud proportion are selected for different geological layers. Dril...

Embodiment 2

[0048] like Figure 8 As shown in the comparison example 1, another embodiment of the present invention is: multiple groups of No. 1 magnets 9 are fixed inside the roller 31 ; Described No. 1 magnet 9 and No. 2 magnet 91 magnetic repulsion; During work, in the contact process of roller 31 and wave groove 3, the magnetic repulsion between No. 1 magnet 9 and No. 2 magnet 91 can assist roller 31 When moving, the magnetic force of No. 1 magnet 9 and No. 2 magnet 91 are used to repel each other, which can accelerate the disengagement speed of the roller 31 and the wave groove 3, and provide a smooth support for the outward disengagement of the pressing plate 23.

[0049] When working, the tee pipes 12 installed on the ends of the multiple sets of sewage pipes 11 and the tee pipes 12 can communicate with each other and drain the sewage, so as to keep the sewage well 13 in a dry environment. When the pipe 1 communicates with the sewage pipe 11 and the tee pipe 12, according to the e...

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a sewage well temporary jump drainage construction method which comprises the following steps that S1, firstly, a worker investigates the sewage flow direction according to the current situation, meanwhile, a scheme and an underground pipeline distribution diagram are determined, the jump drainage well position is placed, a steel protection cylinder is buried under the condition that the inclination is not larger than 0.5%-1%, the inner diameter of the protection cylinder is 19-21 cm larger than the pile diameter, and the steel protection cylinder is placed on a foundation; the top surface of the pile casing is 20-30 cm higher than the construction ground; s2, a positive circulation drilling machine is adopted, a geological profile map is drawn according to geological and hydrological data provided by the construction design, different drill bits, drilling pressures, drilling speeds and proper mud specific gravity are selected for different geological stratums, and low-gear and low-speed drilling is suitable during drilling; through the contact between the extrusion plate and the side walls of the sewage pipe and the three-way pipe, the connectivity can be improved along with the distance between the sewage pipe and the three-way pipe, connection between the sewage pipe and the three-way pipe is kept, support is provided for construction of a tunnel below a sewage well, and the influence on the project progress caused by sewage leakage is reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for temporary skipping of sewage wells. Background technique [0002] With the development of urban rail transit in my country and the continuous maturity of the urban subway network, it is inevitable that there will be overlapping municipal pipeline spaces on the lines of the underground railway. During the excavation of the underground railway tunnel, the municipal pipeline network within the spatial intersection of the subway section must be Carry out relocation processing, otherwise construction will not be possible. [0003] A Chinese patent with publication number CN107905345A discloses an injection mold, which includes the following steps: S001, the controller obtains the sewage inflow rate through a flow meter, and the controller obtains the sewage storage in the sewage well through a water level gauge; S002, the controller o...
