Description

Urban road combination formula safety type inspection shaft

Technical Field

The utility model relates to a municipal facilities field, concretely relates to urban road combination formula safety type inspection shaft.

Background

At present, urban road accumulated water in China is discharged mainly by collecting rainwater through an inspection well on a road surface, and then the rainwater enters a connecting pipeline and is discharged into the downstream. In recent years, the phenomenon that cities are frequently submerged by heavy rain in summer in China is related to large rainfall intensity in summer and also related to insufficient drainage capacity of an inspection well. The water inlet of the inspection well is arranged to be small, so that surface accumulated water cannot enter the inspection well in time to be drained away; meanwhile, the pipeline in the inspection well is unreasonable in arrangement, so that the drainage efficiency is low, and the accumulated water on the road surface is serious.

SUMMERY OF THE UTILITY MODEL

For solving the problem, the utility model discloses a well lid that sets up the inspection shaft can be automatically by the back-up, and road ponding discharges into the inspection shaft with higher speed, adds the wash-out pipe simultaneously in the inspection shaft, strengthens the drainage ability of inspection shaft, promotes the drainage efficiency of inspection shaft, guarantees that road pavement does not produce serious ponding.

The utility model provides a combined safety inspection well for urban roads, which comprises a well body, a well cover positioned at the upper end of the well body and a base positioned at the bottom of the well body;

the outer wall of the well body is respectively connected with a sewage inlet pipe, a sewage outlet pipe and a water drain pipe;

the water drain pipe is respectively vertical to the sewage inlet pipe and the sewage outlet pipe; the sewage inlet pipe and the sewage outlet pipe are respectively arranged on two sides of the bottom of the well body; the drain pipe is arranged in the middle of the well body;

a water inlet is formed in the well cover;

the urban road combined safety inspection well is also provided with a floating piece in the well body; the upper end of the floating piece is welded with one end of the ejector rod, and the other end of the ejector rod is in threaded connection with the middle of the lower end of the well cover.

As an improvement of the utility model, the water drain pipe the pipe diameter of the sewage exit tube is all greater than the pipe diameter of the sewage inlet tube.

As an improvement of the utility model, the ejector pin middle part passes the stand pipe, the stand pipe pass through the support with the well bore inner wall is fixed continuous.

As an improvement of the utility model, the water inlet adopts the grid water inlet.

As an improvement of the utility model, the well body inside wall from the top evenly is provided with the cat ladder.

The utility model has the advantages that: when the road surface accumulated water is serious, the upward movement of the suspension piece can drive the well cover to be automatically opened, and the entry of the road accumulated water into the inspection well is accelerated; the drainage pipe is added in the inspection well, so that accumulated water in the inspection well can be drained through the drainage pipe and the sewage outlet pipe at the same time after reaching a certain amount, and the drainage capacity of the inspection well is enhanced; the manhole cover adopts a grating water inlet to prevent larger objects in road accumulated water from entering the inspection well, so that the inspection well is prevented from being blocked due to the large objects; the climbing ladder is arranged on the inner wall of the well body, so that maintenance and repair personnel can conveniently go down to the well bottom for operation.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, one embodiment of the utility model discloses an urban road combined safety type inspection well, which comprises a well body 1, a well cover positioned at the upper end of the well body 1 and a base 3 positioned at the bottom of the well body 1; the outer wall of the well body 1 is respectively connected with a sewage inlet pipe 11, a sewage outlet pipe 12 and a water drain pipe 13; the water drain pipe 13 is respectively vertical to the sewage inlet pipe 11 and the sewage outlet pipe 12; the sewage inlet pipe 11 and the sewage outlet pipe 12 are respectively arranged at two sides of the bottom of the well body 1; the drain pipe 13 is arranged in the middle of the well body 1; a water inlet 21 is formed in the well cover 2; the urban road combined safety inspection well is also provided with a floating piece 14 in the well body; the upper end of the floating piece 14 is welded with one end of the ejector rod 4, and the other end of the ejector rod 4 is in threaded connection with the middle of the lower end of the well lid 2. When the road seepers seriously and the inspection well seepers more and submerges the suspension piece, the suspension piece moves upwards due to buoyancy to drive the ejector rod to jack the well cover, so that the road seepers flow into the inspection well at an accelerated speed; when the depth of the accumulated water in the inspection well is larger than the height between the drain pipe and the bottom of the well, the accumulated water in the inspection well can be discharged through the drain pipe and the sewage outlet pipe simultaneously, the drainage capability of the inspection well is enhanced, and the serious accumulated water on the road surface is avoided.

In this embodiment, the pipe diameters of the drain pipe 13 and the waste water outlet pipe 12 are both larger than the pipe diameter of the waste water inlet pipe 11. The drainage speed of the inspection well can be guaranteed to be higher than the water inlet speed, and serious water accumulation in the inspection well can be avoided.

In this embodiment, the middle of the mandril 4 passes through a guide pipe 5, and the guide pipe 5 is fixedly connected with the inner wall of the well bore 1 through a support 6. The well lid is guaranteed not to be washed away by water after being jacked open.

In this embodiment, the water inlet 21 is a grid water inlet. The inspection well can prevent large objects in the road accumulated water from entering the inspection well, and the blockage of the inspection well caused by large objects is avoided.

In this embodiment, the inner side wall of the well body 1 is uniformly provided with the climbing ladder 15 from top to bottom. The maintenance and repair personnel can conveniently go down to the well bottom to carry out related operation.

Finally, only the specific embodiments of the present invention have been described in detail. The invention is not limited to the specific embodiments described above. Equivalent modifications and substitutions by those skilled in the art to the present invention are also within the scope of the present invention. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
