Description

Inspection well

Technical Field

The utility model relates to an underground drainage detection facility specifically relates to an inspection shaft.

Background

Inspection wells, commonly known as "inspection wells", are commonly located at junctions of drainage pipes, bends, pipe diameter or slope changes, drops, and linear pipe sections at intervals, and are drainage attachment structures for periodic inspection, cleaning, and dredging of pipes. The inspection well is mainly divided into a sewage (waste) water inspection well and a rainwater inspection well. Because the pipe sections between two adjacent wells are on the same straight line, inspection wells are required to be arranged at the positions of changing the section of the pipeline, changing the gradient, meeting and changing the elevation, and the inspection wells are required to be arranged on the overlong straight pipe sections in sections (the section spacing is regulated according to the diameter of the pipeline and the types of rain and sewage).

However, under the influence of too fast city construction, the original sewage outlets on the two banks of the river channel are often limited in occupied space position when sewage intercepting pipelines are laid in the later period, and the high removal and occupation cost is often generated when the river channel with more buildings on the two banks is particularly serious. In addition, the sewage intercepting pipelines laid in the riverway and the riverway side slope often have the defect of inconvenient maintenance because inspection wells cannot be built according to the standard.

In view of the above-mentioned shortcomings of the prior art, there is a need for a new type of manhole.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an inspection shaft to there is the inconvenient problem of maintenance in the pipeline of laying in the river course in the solution.

In order to achieve the above object, the present invention provides an inspection well, which comprises a shaft and a well chamber communicated with the lower end of the shaft, wherein a pipeline laid in the river bed passes through the well chamber.

Preferably, the shaft is vertically disposed within a bank protection.

Preferably, the upper end of the shaft is provided with an inlet hole for access of service personnel, and the inlet hole is closed by a well cover.

Preferably, an inlet hole for access of a service person is formed in the upper end of the shaft, the inspection well further comprises an extension well which extends upwards from the upper end of the shaft and is communicated with the shaft, and the upper end of the extension well is sealed by the well cover.

Preferably, the extension well protrudes upward beyond an upper surface of the bank protection slope.

Preferably, the well chamber extends from a lower end of the wellbore into the river bed.

Preferably, the cross-section of the well chamber taken perpendicular to the direction of extension of the well chamber is rectangular, circular or domed rectangular.

Preferably, a sump is provided on the bottom surface of the well chamber.

Preferably, the sump is located below the wellbore.

In the technical scheme, the shaft is communicated with the well chamber, and the pipeline laid in the river bed passes through the well chamber, so that the pipeline in the river bed can be maintained conveniently. To the construction of whole sewage intercepting pipeline, the position of inspection shaft probably produces very little occupation of land, and other most take up an area of and all are located the riverbed to both can reduce the occupation of land scope of pipe laying, also solved the inconvenient problem of pipeline maintenance in the riverbed, be applicable to the river course and intercept the restricted condition of occupation of land in the engineering.

Other features and advantages of the present invention will be described in detail in the detailed description which follows.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

The utility model provides an inspection well, this inspection well include pit shaft 1 and with the well chamber 2 of the lower extreme intercommunication of pit shaft 1, lay pipeline 3 in the riverbed and pass from well chamber 2. The shaft 1 is communicated with the well chamber 2, and a pipeline laid in the river bed penetrates through the well chamber 2, so that the pipeline in the river bed can be maintained conveniently. To the construction of whole sewage interception pipeline, the position of inspection shaft probably produces very little occupation of land, and other most occupation of land all are located the riverbed to both can reduce the occupation of land scope of pipe laying, also solved the inconvenient problem of pipeline maintenance in the riverbed, be applicable to the restricted condition of occupation of land among the river course sewage interception engineering.

Specifically, as shown in fig. 1 and 2, the shaft 1 is vertically disposed within the bank protection 6. An inlet hole 4 for the entry and exit of the inspection person is provided at the upper end of the shaft 1, and the inlet hole 4 is closed by a well lid 7. A service person can enter the manhole from the entry hole 4 on the bank and through the shaft 1 into the well chamber 2 to facilitate maintenance of the conduit in the bed. In another embodiment, the upper end of the shaft 1 is provided with an inlet hole 4 for access of service personnel, and the inspection well further comprises an extension well 8 extending upwards from the upper end of the shaft 1 and communicating with the shaft 1, and a well cover 7 closing the upper end of the extension well 8. The arrangement of the extension shaft 8 is determined according to the structure of the bank protection slope 6 and the depth of the upper end of the shaft 1. Also, the extension well 8 preferably protrudes upward beyond the upper surface of the bank protection 6 to facilitate maintenance of the inspection well.

Further, the well chamber 2 extends from the lower end of the shaft 1 into the river bed, thereby forming an "L" shaped structure. The cross-section of the well chamber 2 taken perpendicular to said extension direction of the well chamber is rectangular, circular or domed rectangular. The round top rectangle is a rectangle with the upper side replaced by an arc, namely a figure formed by connecting the arc and three straight line segments end to end. The pipeline 3 laid in the river bed passes through the well chamber 2, and maintainers can enter the well chamber 2 to overhaul the pipeline 3.

In addition, a water collecting pit 5 is arranged on the bottom surface of the well chamber 2, and accumulated water in the well chamber 2 can flow into the water collecting pit 5, so that accumulated water on the bottom surface of the well chamber 2 (especially the bottom surface close to the pipeline 3) is prevented, and the overhaul work of maintainers is facilitated. In particular, the sump 5 is located below the shaft 1, away from the pipes 3 laid in the river bed.

The pipeline 3 is a sewage intercepting pipeline which is laid in a riverbed along a river channel and is 2-3 m away from the side line of the river. To the construction of whole sewage intercepting pipeline, the position of inspection shaft probably produces very little occupation of land, and other most take up an area of and all are located the riverbed to both can reduce the occupation of land scope of pipe laying, also solved the inconvenient problem of pipeline maintenance in the riverbed, be applicable to the river course and intercept the restricted condition of occupation of land in the engineering. For example, the river course base current in northern area is less, and construction convenience adopts in the river course the utility model discloses an inspection shaft is favorable to city pipeline construction very much.
