Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 and Figure 4 As shown, the plastic depressurization inspection well includes a wellbore 1, a wellbore socket 2 located at the top of the wellbore 1, a branch pipe socket 3 arranged on the side wall of the wellbore 1, and a reinforced wall section 4 extending from the sidewall of the wellbore 1 to the bottom of the wellbore 1 ; There are usually one to four branch sockets 3; at least one pressure relief hole 41 is provided on the reinforced wall section 4, and the pressure relief hole 41 is a through hole. The reinforced wall section 4 is a reinforced structure extending from the bottom of the shaft 1 to ensure the overall strength of the shaft 1 . The pressure relief hole 41 is a through hole provided on the reinforced wall section 4, and is used to discharge the pressure of groundwater and gas on the bottom of the inspection well from the side of...

Abstract

The invention discloses a plastic pressure-reduction inspection well capable of reducing the pressure of underground water and gas to the bottom of the inspection well. The inspection well comprises a shaft, a shaft bell mouth located at the top end of the shaft, a branch pipe bell mouth disposed on the lateral wall of the shaft, and a reinforcing wall section extending from the lateral wall of the shaft and extending out of the bottom of the shaft. The reinforcing wall section is provided with at least one through pressure relief hole. The plastic pressure-reduction inspection well has the advantages that the pressure of the underground water and gas to the bottom of the inspection well can be discharged from the lateral side of the inspection well through the pressure relief holes, the inspection well is prevented from being damaged by pressure or floating upwardly to shatter filling and cause collapse, and the service life of the plastic inspection well is prolonged.

Description

technical field [0001] The invention belongs to the field of water supply and drainage, and in particular relates to a plastic pressure-reducing inspection well. Background technique [0002] Inspection wells are vertical shafts installed at certain distances or at a certain point in underground pipelines. Inspection wells are generally located at the turns, junctions, pipe diameter or slope changes of drainage pipes, cable pipes, etc., and at intervals on straight pipe sections. A certain distance and the water drop of the drainage pipe. The inspection well is an auxiliary structure used to repair pipelines, remove sludge and connect pipelines in different directions and heights. Specifically, there are sewage inspection wells, street inspection wells, sediment inspection wells, water separation inspection wells, electric power inspection wells, telecommunications inspection wells, pipeline valve inspection wells, etc. Plastic inspection wells have the advantages of light...
