For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As shown in the accompanying drawings, the utility model includes a well body 1 and a well cover 2 installed on the top of the well body 1. The well body 1 is an eccentric cone structure with openings on both the top and the bottom. Cable connection holes 3 are provided on the cylinder walls on the front and rear sides of the well body 1, and cable passing holes 4 are provided on the cylinder walls on both sides adjacent to the cable connection holes 3.

[0021] Preferably, the eccentric cone structure is an eccentric right-angle cone, that is, one side of the entire inspection well is a vertical structure, and the center line is offset to one side, so that the space in the entire well body 1 gradually increases downward, and there is enough space on one side for workers to live and operate, which is convenient for operation.

[0022] Before installation, a pit is dug on the ground and a cushion layer is poured with concrete. Then the well body 1 is hoisted onto the poured cushion layer. The cable connection hole 3 is used to connect the lines inside the well body 1 with those outside the well body 1, and the cable passing hole 4 is used for laying the cable.

[0023] Furthermore, a manhole cover mounting tube 5 extending upward is integrally cast at the top of the well body 1, and a base 6 extending downward is integrally cast at the bottom of the well body 1. The manhole cover 2 is hinged in the manhole cover mounting tube 5 by a pin shaft, and the manhole cover mounting tube 5 is provided with a manhole cover limiting edge 7 protruding inward.

[0024] In this case, the height of the well body 1 is 900mm, the top inner diameter of the well body 1 is 700mm, the bottom inner diameter of the well body 1 is 1000mm, the height of the manhole cover mounting tube 5 is 100mm, the height of the base 6 is 200mm, and the manhole cover mounting tube 5 and the base 6 are integrally cast with the well body 1.

[0025] Furthermore, a sewage sedimentation tank 8 is provided in the manhole cover installation tube 5. The sewage sedimentation tank 8 is annular and has a circle of outwardly protruding hanging parts 9. The sewage sedimentation tank 8 is movably installed on the manhole cover limiting edge 7 through the hanging parts 9.

[0026] The sewage sedimentation tank 8 is located in the manhole cover installation tube 5. When sewage enters from the gap of the manhole cover 2 on rainy days, it will first flow into the sewage sedimentation tank 8. The sewage can enter the well body 1 after preliminary sedimentation in the sewage sedimentation tank 8, which can effectively reduce the sediment falling into the well body 1.

[0027] When the staff needs to enter the well body 1 for operation, they can first remove the sewage sedimentation tank 8 and then enter, and at the same time, the sediment in the sewage sedimentation tank 8 is also cleaned.

[0029] Furthermore, the manhole cover 2 is provided with an opening hole 12 and a locking hole 13 , the locking hole 13 is provided with a locking piece 14 , and the manhole cover mounting tube 5 is provided with a locking groove matched with the locking piece 14 .

[0030] The opening hole 12 is used for an iron hook to extend into and pull the manhole cover 2 outward, and the locking hole 13 is used to control the locking or opening of the manhole cover 2 and the well body 1.

[0031] Preferably, the locking member 14 includes a lock core 15 and a lock block 16 , the lock block 16 is slidably mounted on the manhole cover 2 , and the lock core 15 is rotatably mounted in the locking hole 13 and drives the lock block 16 to move.

[0033] That is, when the lock cylinder 15 is rotated, the lock block 16 and the movable sealing block 17 move in opposite directions synchronously. The movable sealing block 17 is located below the opening hole 12 when the manhole cover 2 is locked, and the opening hole 12 is blocked to reduce the entry of debris and sewage. After the lock block 16 of the manhole cover 2 is opened, the movable sealing block 17 is also moved away from below the opening hole 12, and the iron hook can enter to open the manhole cover 2 outward.

[0034] The inspection wells in this case are set up every 50 meters in the straight section of the power engineering cable trench; set up at the corners of the cable trench; set up at both ends of the road where the cable crosses; and set up in a single well for a single lamp on a multi-functional street lamp pole.

[0035] Applicable to concrete pipes with a diameter of D<200mm, resin concrete pipes, buried plastic pipes, composite plastic pipes, ductile iron pipes and cast iron pipes, etc.
