The lower wall unit 1 includes a lower ring 101, a pipe hole 102 provided on the lower ring 101, a bottom plate 103 provided on the lower ring 101, and a lower annular groove 104 provided on an upper surface of the lower ring 101 and used for mounting the seal ring 3.
In this embodiment, the materials of the lower wall unit 1 and the upper wall unit 2 are both concrete or reinforced concrete structures, and the pipe hole 102 is used for plugging, or is in sealing connection with a water supply and drainage pipe after plugging, the former corresponds to a closed pipe, the pressure of the waterproof performance is relatively small, mainly preventing the entry of soil water, the latter corresponds to an open pipe, the pipe is disconnected in the inspection well, and at this time, the pressure of the waterproof performance is relatively large, so that the water needs to be prevented from flowing out in a large amount.
The lower wall unit 1 further comprises a projection 105 arranged on the upper surface of the lower ring 101 and used for clamping the upper wall unit 2.
In this embodiment, the bump 105 is used to pre-align the upper wall unit 2, after the alignment, the vertical and horizontal positions of the upper wall unit 2 are accurate, only the final rotation adjustment is needed, and the sealing ring 3 is fully and properly compressed at this time, so that it is ensured that the water between the lower wall unit 1 and the upper wall unit 2 is relatively difficult to leak out.
The upper well wall unit 2 comprises an upper circular ring 201; the first symmetrical annular grooves 202 are arranged on the upper surface and the lower surface of the upper circular ring 201 and are respectively used for installing the sealing ring 3 and the clamping well lid unit 5; and 2 second symmetrical annular grooves 203 provided on the upper and lower surfaces of the upper ring 201 and respectively for engaging the projection 105 and mounting the vertical screw unit 4.
In this embodiment, the inner diameter and the outer diameter of the upper ring 201 are the same as those of the lower ring 101, and the first symmetrical ring groove 202 and the second symmetrical ring groove 203 are symmetrically arranged and are "one-thing-two-purpose", so that the upper wall unit 2 is finally ensured to be in a vertically symmetrical shape structure, and therefore, the installation is more convenient without paying special attention to the vertical direction.
The vertical screw unit 4 includes an internal thread groove 401 provided on the upper surface of the lower ring 101, a vertical through hole 402 provided between the upper and lower two second symmetrical annular grooves 203, a screw 403 provided on the vertical through hole 402 and screw-connected to the internal thread groove 401, and a fastening nut 404 provided in the upper second symmetrical annular groove 203 and used for connecting the screw 403.
In this embodiment, the internal thread groove 401 may be formed on the upper surface of the lower ring 101 by being cut down or by being cut out, or may be formed by being placed into an internal thread tube before the lower ring 101 is cured.
The fastening nuts 404 are located in the second symmetrical annular groove 203, and 2-3 fastening nuts 404 are disposed on a single screw 403, so as to ensure higher-strength screwing stability.

In this embodiment, after the engaging block 502 is engaged with the first symmetrical annular groove 202 above, the entire manhole cover unit 5 is difficult to laterally shift, i.e. the manhole cover is not easily exposed, which is very safe.
The diameter of the circular cover 501 is equal to or greater than the outer diameter of the upper ring 201.
In this embodiment, when the diameter of the circular cover 501 is equal to the outer diameter of the upper ring 201, the circular cover 501 needs to be provided with an opening for hooking the manhole cover, and when the diameter of the circular cover 501 is greater than the outer diameter of the upper ring 201, the opening may not be provided, and at this time, the circular cover 501 is held by the holding side, and still can be lifted conveniently.
The projection 105 is disposed radially outward of the lower annular groove 104.
In this embodiment, if the protrusion 105 is located inward, the second symmetrical annular groove 203 and the vertical screw unit 4 are all located inward, and water leaks at the vertical through hole 402, which needs to be avoided.
In addition, as shown in fig. 3, the protruding blocks 105 and the internal thread grooves 401 are arranged according to the co-circular position relationship and are staggered in the circumferential direction, so that the pre-alignment of the protruding blocks and the vertical screwing action of the protruding blocks are ensured, the protruding blocks and the internal thread grooves are not mutually interfered, and one second symmetrical annular groove 203 is occupied respectively.
The lateral cross-sectional shapes of the protruding block 105 and the clamping block 502 are sector-shaped.
In this embodiment, the fan-shaped block structure may be more fit with the annular groove, where the former ensures that the upper ring 201 may be more accurately aligned with the lower ring 101, and the latter ensures that the circular cover 501 may be more accurately aligned with the upper ring 201.
The number of the vertical screw units 4 is 2-3.
In this embodiment, the number of vertical screw units 4 cannot be too large, otherwise the workload of the manhole in installation is significantly increased, but the number thereof cannot be too small, otherwise the lower wall unit 1 and the upper wall unit 2 cannot be sufficiently fixed, and thus the number range of 2-3 is determined.
Finally, the advantages of the spliced water supply and drainage inspection well in this embodiment are summarized as follows.
The first inspection well structure is only divided into the lower well wall unit 1 and the upper well wall unit 2, and the lower well wall unit 1 and the upper well wall unit 2 are not separated, so that relatively fewer splicing gaps are ensured, and the inspection well has good basic sealing performance.
And a sealing ring 3 which is fully and properly pressed and filled is arranged between the lower well wall unit 1 and the upper well wall unit 2, so that the largest splicing gap of the well body is not easy to leak water.
Thirdly, the vertical screw connector unit 4 is in screw connection with the lower well wall unit 1, and is inserted into and tightly pressed against the upper well wall unit 2, so that the lower well wall unit 1 and the upper well wall unit 2 are difficult to separate and disassemble, and the whole inspection well has higher structural strength.
Fourth, the upper and lower ends of the upper well wall unit 2 can be used upside down, and the upper well wall unit and the lower well wall unit are installed without distinction, so that the upper well wall unit and the lower well wall unit are very convenient and quick.
Fifth, there is a pre-alignment between the projection 105 and the second symmetrical annular groove 203, where the vertical and horizontal positions of the upper borehole wall unit 2 are all in place, only with the final proper rotational adjustment, and where the sealing ring 3 is also fully installed.
Sixth, the protrusion 105 and the internal thread groove 401 are disposed in a common circle, so that the second symmetrical annular groove 203 has both a pre-alignment function and a function of allowing the screw 403 to pass through.
Seventh, the well lid unit 5 is not easy to shift on the upper ring 201, and can cover the first symmetrical ring groove 202 and the second symmetrical ring groove 203, so as to avoid the blockage of the first symmetrical ring groove 202 and the second symmetrical ring groove 203 by sundries.
