Description

Acute angle inspection well

Technical Field

The utility model relates to the field of drainage engineering, in particular to a turning structure of urban drainage pipelines.

Background

The urban drainage is mostly laid by gravity flow, and the branch pipes collect rainwater or sewage, collect the rainwater or sewage to the main pipe, and finally collect the rainwater or sewage to the main pipe to be discharged into a water body or a sewage treatment plant. The drainage pipeline is required to be provided with an inspection well at the positions of turning, pipeline diameter change, gradient change, pipe bottom elevation change and the like. In the drainage pipeline design in the prior art, an inspection well generally adopts a standard diagram, and the inspection well in the existing national standard diagram 06MS201 municipal drainage pipeline engineering and accessory facilities has the pipe diameter range of d200-d2000 and the turning angle of 90-180 degrees. In order to ensure the stability of hydraulic fluid state, the turning angle of the inspection well generally cannot be less than 90 degrees. In actual engineering, due to the existence of obstacles, the situation that the upstream and downstream pipelines form an acute angle often occurs, and the problem is generally solved by adding at least two turning wells. Increasing the number of inspection wells increases the construction cost and occupies a large underground space.

Therefore, a technical scheme for solving the problem of water conservancy flow state under the condition of not increasing occupied land and investment as much as possible is urgently needed in the prior art.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned deficiencies of the prior art, the present invention provides an acute angle manhole.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the utility model provides an acute angle inspection shaft, includes the well body, well room, chute, inlet tube, outlet pipe, pit shaft and well lid, the well room is located in the well body, the inlet tube with the outlet pipe all with the well room is connected, the inlet tube with pass through between the outlet pipe the chute is connected, the pit shaft sets up the top of the well body, the well lid sets up the top of pit shaft.

The included angle between the water inlet pipe and the water outlet pipe is an acute angle not less than 60 degrees.

And d is the diameter of the water inlet pipe, the width of the well body corresponding to the position of the water inlet pipe is c, and c is more than or equal to (d +800 mm).

The well body has the corner, and the corner is total two, and the angle of buckling at the corner is not less than 90.

And setting the length of a well body at the corner of the well chamber as b, and setting the width of the well body corresponding to the water inlet pipe as c, wherein b is more than or equal to 2 c.

Compared with the prior art, the utility model has the beneficial effects that: the acute angle inspection well occupies small area, is suitable for the condition that the water inlet pipe and the water outlet pipe form an acute angle, and can be applied to the collection and conveying engineering of urban rainwater, sewage and industrial sewage.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The acute angle inspection well shown in the figures 1-2 comprises a well body 1, a well chamber 2, a launder 3, a water inlet pipe 4, a water outlet pipe 5, a shaft 6 and a well cover 7, wherein the well chamber 2 is positioned in the well body 1, the water inlet pipe 4 and the water outlet pipe 5 are both connected with the well chamber 2, the water inlet pipe 4 and the water outlet pipe 5 are connected through the launder 3, and the launder 3 is built by concrete or bricks or dry masonry. The shaft 6 is arranged on the top of the well body 1, and the well cover 7 is arranged on the top end of the shaft 6. The well body 1 is special-shaped, and the well body 1 has the turning, and the turning totally has two, and the angle of buckling of turning is not less than 90, and two angles of buckling all are the obtuse angle promptly, are favorable to the fluid to flow in chute 3. The length of the well body at the corner of the well chamber 2 is b, the width of the corresponding well body at the water inlet pipe 4 is c, and b is more than or equal to 2 c. The diameter of the water inlet pipe 4 is d, the width of the well body corresponding to the position of the well body 1 and the water inlet pipe 4 is c, and c is more than or equal to d +800 mm.

The included angle between the water inlet pipe 4 and the water outlet pipe 5 is an acute angle not less than 60 degrees. The design of the acute angle enables the horizontal occupied area of the inspection well to be small, and underground space is saved.

The above description is only for the preferred embodiment of the present invention, but the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes and modifications without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
