Embodiment 1

[0028] Such as figure 1 As shown, the inspection well provided by this embodiment includes a support main body 1 and a well cover 2. The well cover 2 is provided with a threaded through hole 21, and the upper end of the support main body 1 is provided with a threaded hole 13 matching the threaded through hole 21. The threaded through hole 21 is connected with the threaded hole 13 through the bolt 3 to connect the well cover 2 with the upper end of the support body 1 .

[0029] The inspection well of the present invention uses bolts to cooperate with the threaded through holes of the well cover and the threaded holes of the support body to fix the well cover on the support body. Compared with the iron chain anti-theft structure of the prior art, the bolt anti-theft structure of the present invention It is more flexible. When installing or dismounting, a specific tool should be used to screw the bolt into or out of the threaded hole, which improves the performance of anti-theft ...

Embodiment 2

[0036] The difference between this embodiment and the first embodiment above is that, if figure 2 and image 3 As shown, the support body 1 further includes a lifting support 12 connected to the bottom support 11 , and the lower surface of the lifting support 12 is built on the upper surface of the first supporting platform 111 . In this embodiment, the first support platform of the bottom support is provided with a lifting support for increasing the height of the main body of the support. At this time, the lower surface of the lifting support is set on the upper surface of the first support platform.

[0037] Wherein, the inner wall of the lifting support 12 is provided with a second support platform 121 extending horizontally inward. The second support platform has the same function as the first support platform. According to the height requirements of the actual construction for the main body of the support, the second support platform can be used to set up the manhole co...

Abstract

The invention relates to the technical field of road construction, and particularly relates to an inspection well. The inspection well comprises a support main body and a well cover, wherein a threaded through hole is formed in the well cover; a threaded hole which is matched with the threaded through hole is formed in the upper end of the support main body; and the threaded through hole and the threaded hole are connected by using a bolt so as to connect the well cover and the upper end of the support main body. The inspection well has the beneficial effects that the bolt is used for being matched with the threaded through hole of the well cover and the threaded hole of the support main body so as to fix the well cover on the support main body; compared with an iron chain anti-theft structure of the prior art, the bolt anti-theft structure of the inspection well has better flexibility; when the inspection well is installed or disassembled, the bolt is screwed into the threaded hole or screwed out from the threaded hole by using a specific tool, so that the anti-theft property and the anti-loss property are improved; and the well cover and the support main body are connected by using the bolt so as to avoid the condition that when the well cover is treaded by pedestrians and rolled by vehicles, the well cover moves relative to the support main body and impacts the support main body to make noise.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an inspection well. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. Inspection wells are used in building districts, residential areas, public building areas, factory areas, etc., and are generally located at the intersection, turning, pipe diameter or slope change, water drop, etc. of drainage pipes, in order to facilitate regular inspection, cleaning and dredging Or a well-shaped structure for downhole operation and insp...
