Water division inspection well

Abstract

The invention relates to a water division inspection well, and belongs to the technical field of underground pipeline fittings. The water division inspection well comprises a well shaft, a well base, a water inlet pipe and a water outlet pipe, wherein the upper end of the well base is connected with the well shaft; the water inlet pipe and the water outlet pipe are respectively connected to the well base, and the height of the bottom end of the water inlet pipe is higher than that of the top end of the water outlet pipe; a connecting pipe is arranged between the water inlet pipe and the water outlet pipe; the connecting pipe comprises a pipe head, a pipe body and a pipe tail; the pipe head is inserted in the water inlet pipe; a seal ring is arranged between the pipe head and the water inlet pipe; the pipe tail is inserted in the water outlet pipe; an annular fence is arranged at the bottom end of the well base; the fence and the well base are encircled to form a water accumulation tank with an open upper end; drain holes are formed in the side wall of the well base; a drain ring is arranged outside the well base in a sleeving mode; the drain ring is connected with a drain pipe. The inspection well has an anti-reflux effect. Reflux water is accumulated in the inspection well, and when the accumulated water exceeds a warning line, the accumulated water flows in the water accumulation tank over the fence, then flows in a drain cavity through the drain holes, and finally drains through the drain pipe.

Description

technical field [0001] The invention belongs to the technical field of underground pipeline fittings, and in particular relates to a water diversion inspection well. Background technique [0002] The water diversion inspection well includes a water inlet pipe and a water outlet pipe. The water inlet pipe leads the water from the water source to the inspection well, and the water outlet pipe leads the water in the inspection well out. Traditional inspection wells generally adopt brick masonry structure, whose elastic modulus is about 1200MPa, which can be regarded as a rigid structure, while the elastic modulus of general backfill soil is only 30MPa~80MPa when the compaction degree reaches 95%, which can be considered Therefore, the junction between the inspection well and the asphalt concrete pavement belongs to the rigid-flexible transition zone, and it is very difficult to achieve structural connectivity during construction. Although the inspection well can be flush with t...

Problems solved by technology

Traditional inspection wells generally adopt brick masonry structure, whose elastic modulus is about 1200MPa, which can be regarded as a rigid structure, while the elastic modulus of general backfill soil is only 30MPa~80MPa when the compaction degree reaches 95%, which can be considered Therefore, the junction between the inspection well and the asphalt concrete pavement belongs to the rigid-flexible transition zone, and it is very difficult to achieve structural connectivity during construction. Although the inspection well can be flush with the road around the well during construction, but in the later stage Due to the difference in deformation during use, the height difference between the inspection well and the ground around the well not only affects the use and appearance of the road, but more seriously affects driving safety and even causes traffic accidents

[0003] On the other hand, when the downflow is blocked, the water will flow back and flow back to the water source through the water inlet pipe, causing pollution of the water source
