Anti-overflow inspection well
The invention discloses an anti-overflow inspection well, and belongs to the technical field of underground pipe fittings. The anti-overflow inspection well comprises a shaft, a water outlet pipe, a water inlet pipe, a water storage sleeve and an overflow pipe, wherein the water outlet pipe and the water inlet pipe are communicated with each other at the bottom of the shaft; the shaft is provided with a crawling ladder; an overflow opening is formed in the side wall of the shaft, and is located above the water outlet pipe and the water inlet pipe; the water storage sleeve sleeves the outer wall of the shaft and forms a water storage cavity together with the shaft; the overflow pipe is communicated with the water storage cavity, is connected with the water storage sleeve and is communicated with the water storage cavity; the inspection well is provided with an overflow device; when the water level in the inspection well is over high, partial water flow is drained through the overflow device, so that the water level in the inspection well is kept within a reasonable limit. The overflow device of the inspection well is arranged below a platform, so that the water level in the inspection well does not submerge the platform; downhole maintenance of operating personnel is facilitated; the operating personnel are not soaked by over-high water level; the operating environment in a rainy day is improved.
