Embodiment Construction

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0024] Such as Figure 1 to Figure 4 As shown, the present invention provides a dewatering well plugging structure, including a cover plate 1, a first through hole 2 is opened in the center of the cover plate 1, and 48 fastener fixing holes 3 are opened in an array around the first through hole 2 , the concrete surface around the wellhead of the dewatering well is provided with 48 corresponding installation holes 4, and the fasteners pass through the fastener fixing holes 3 and are screwed with the installation holes 4 to realize the fixing of the cover ...

Abstract

The invention relates to a dewatering well plugging structure and a construction method thereof. The dewatering well plugging structure comprise a cover plate, wherein a first through hole is formed in the center of the cover plate; a plurality of fastener fixing holes are formed around the first through hole; a sleeve is fixedly assembled at the bottom of the cover plate; the sleeve is coaxiallyarranged with the first through hole; an upper plugging steel plate is fixedly assembled in the sleeve; a second through hole is formed in the center of the upper plugging steel plate, a water pumpingsteel pipe is slidably assembled in the second through hole, a plurality of third through holes are formed around the second through hole, and brackets are slidably assembled in the third through holes; bottom plugging steel plates are fixedly assembled at the bottoms of the brackets, a valve is arranged on the water pumping steel pipe, and the valve is located above the upper plugging steel plate. The dewatering well plugging structure and the construction method thereof have the advantages of economy, practicability, simplicity, practicability, good plugging quality, prevention of bottom plate leakage, stable overall structure and high bearing capacity, and the highest bearing capacity can reach 800 kN.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a construction method for a plugging structure of a dewatering well. Background technique [0002] With the development and utilization of underground space, the excavation depth of underground engineering is getting deeper and deeper. Construction under the condition of high water level is easy to cause problems such as soil slippage, water leakage of support structure, and foundation pit instability. In order to ensure construction safety, it is necessary to take effective measures to reduce the groundwater level. The usual method is to arrange a certain number of precipitation wells in the floor of the building for precipitation treatment. However, for dewatering wells with high water pressure and large water output, how to seal the wellhead has always been a construction problem, and there is no good solution at present.
