After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

1. The inspection well is prefabricated as a whole. The construction site only needs to build the foundation and well pit, which greatly shortens the construction period. At the same time, because the inspection well is prefabricated and poured as a whole, there is no leakage problem that is common in on-site masonry;

2. According to the depth of the inspection well buried underground, the height adjustment ring is used to adjust the height of the wellhead, which can make the wellhead flush with the road surface and solve the problem of bumps when vehicles pass by;

3. The wellbore is divided into two detachable parts by the horizontal diameter of the pipe hole. When installing the pipe, lift the upper half so that the pipe can be installed on the half pipe hole in the lower part, which is convenient for pipe installation;

4. The cover plate cooperates with the stepped structure on the upper edge of the shaft to improve the sealing effect and prevent displacement;

5. The cover plate and the height adjustment ring are fixed by pre-embedded steel bar pouring, which improves the reliability of installation;

6. There are handrails inside the shaft, which is convenient for personnel maintenance;

7. The sealing ring ensures that all parts are sealed well to further avoid leakage;

8. Special-shaped nuts are set on the pre-embedded bolts to fix the well ring or well cover. Non-professional tools cannot unscrew the nuts, which plays a role in preventing theft to a certain extent.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and a specific embodiment, so as to help understand the content of the present invention.

As shown in Figures 1-7, the integrally assembled multifunctional inspection well includes a prefabricated shaft 1, a prefabricated cover plate 2 and a prefabricated height adjustment ring 3; the upper end of the well shaft 1 is open; the cover plate 2 is installed on The upper end opening of the shaft 1; the cover plate 2 is provided with a hole matching the diameter of the height adjustment ring 3; the lower end of the height adjustment ring 3 is fixedly installed on the cover plate 2; The upper edge of the height adjustment ring 3 is provided with embedded bolts 4 for fixing the well ring 5 or the well cover. Special-shaped nuts are set on the pre-embedded bolts 4 to fix the well ring 5 or the well cover, and non-professional tools can not unscrew the nuts, which has played an anti-theft effect to a certain extent. The inspection well is prefabricated as a whole, and the construction site only needs to build the foundation and well pit, which greatly shortens the construction period. At the same time, because the inspection well is prefabricated as a whole, there is no leakage problem that is common in on-site masonry. According to the depth of the inspection well buried underground, the height of the wellhead is adjusted by the height adjustment ring 3, which can make the wellhead flush with the road surface and solve the bumping problem when the vehicle passes by; The distance between the upper end and the road surface.

A pipe hole 6 is arranged on the shaft 1, and the shaft 1 is divided into two detachable upper and lower parts by the surface where the horizontal diameter of the pipe hole 6 is located. When installing the pipeline, the upper half 101 is lifted so that the pipeline is installed on the half pipeline hole 6 of the lower half 102, which is convenient for pipeline installation. After the pipeline is installed, the upper half 101 and the lower half 102 are aligned and installed, and the pipeline can just It is in the pipe hole 6 that is assembled in the upper and lower parts. In this way, the inconvenience of stuffing a very long pipeline into the pipeline hole 6 is avoided.

The upper edge of the wellbore 1 is depressed downward near the central part of the wellbore 1 to form a depression, and the upper edge of the wellbore 1 is away from the central part of the wellbore 1 to form a convex part, and the concave part and the convex part form a stepped shape; The inner edge of the protrusion matches the outer edge of the cover plate 2 . The cover plate 2 cooperates with the stepped structure on the upper edge of the shaft 1 to improve the sealing effect and prevent displacement.

The cover plate 2 and the height adjustment ring 3 are fixed by on-site casting; the specific method is that the cover plate 2 is provided with a pre-embedded steel bar 7, and the height adjustment ring 3 is provided with a reserved hole 8 and the pre-installed The grouting holes 9 communicated with the reserved holes 8, and the embedded steel bars 7 cooperate with the reserved holes 8. If the pre-embedded steel bar 7 extends into the reserved hole 8, cement mortar is poured into the reserved hole 8 from the grouting hole 9. After solidification, the cover plate 2 and the height adjustment ring 3 form a relatively fixed body.

For the convenience of personnel maintenance, handrails 11 are provided on the inner wall of the well shaft 1 .

In addition, a sealing ring 10 may be provided between the cover plate 2 and the shaft 1 . A sealing ring 10 may also be provided between the height adjustment ring 3 and the cover plate 2 . The sealing ring 10 ensures that each part is well sealed to further avoid leakage.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
