Description

A new type of pipe-jacking well

technical field

The utility model relates to the field of water supply pipe networks, in particular to a novel pipe-jacking well.

Background technique

Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. After one section of pipe has been jacked into the soil layer, the second section of pipe will continue to be jacked. Its principle is to push the tool pipe or roadheader from the working pit through the soil layer to the receiving pit by means of the thrust of the main top oil cylinder, the pipeline room, and the relay room. The pipeline is buried between the two pits immediately after the tool pipe or the roadheader.

Trenchless engineering technology has completely solved the problems of damage to urban buildings and road traffic congestion during pipeline burying construction, and has highlighted its advantages in terms of stabilizing soil layers and environmental protection. This is very important for cities with heavy traffic, dense population, numerous ground buildings and complicated underground pipelines. It will create a clean, comfortable and beautiful environment for the city.

The current pipe jacking well is a dry well. In order to facilitate maintenance, a wet well is generally installed on one side of the dry well to discharge the water in the pipe jacking during maintenance. However, the pipe jacking well with this structure has a relatively large size. Increased investment, and inconvenient operation.

Utility model content

The purpose of this utility model is to provide a new type of pipe jacking well for the deficiencies and defects of the prior art. The new type of pipe jacking well can effectively discharge the water in the pipe jacking during maintenance, and there is no need to set up a wet well, which can solve the above problems .

The technical problem solved by the utility model can be realized by adopting the following technical solutions:

A new type of pipe jacking well, comprising a pipe jacking section arranged in the pipe jacking well, characterized in that at least one drainage pipe communicating with it and extending out of the ground is arranged at the lower part of the pipe jacking section, and the drainage pipe extends out of the ground and An inspection valve is arranged on the upper part of the drain pipe, and at least one inlet and exhaust valve is arranged on the upper part of the pipe jacking section.

In a preferred embodiment of the present utility model, an operation platform is provided on the top of the pipe jacking well, through which the staff can control the operation of the maintenance valve and the intake and exhaust valves.

In a preferred embodiment of the present invention, the top of the operating platform is provided with a manhole for workers to enter.

Due to the adoption of the above technical scheme, the beneficial effect of the utility model is that: during the inspection and maintenance of the pipe jacking well, the water in the pipe jacking can be effectively discharged through the drain pipe, and the pipe jacking well is a dry well, so that dry and wet separation can be realized without additional Setting the wet well greatly reduces the size of the pipe jacking well, reduces investment costs, and can also balance the air pressure inside the pipe jacking through the intake and exhaust valves.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the accompanying drawings that need to be used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the accompanying drawings in the following description These are only some embodiments of the present utility model, and those skilled in the art can also obtain other drawings according to these drawings without creative work.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to a new type of pipe jacking well shown in Fig. 1, it includes a pipe jacking section 200 arranged in the pipe jacking well 100, and a drainage pipe 300 communicating with it is arranged at the bottom of the pipe jacking section 200. Of course, the number of drainage pipes 300 can be adjusted according to needs. set up. The top of the drainpipe 300 extends out of the ground, and the top of the drainpipe 300 is blocked by a blind plate 320 , and an inspection valve 310 is set on the top of the drainpipe 300 . At least one intake and exhaust valve 210 is also provided on the upper part of the pipe jacking section 200 .

In order to facilitate the operation of the staff, an operation platform 400 is provided on the top of the pipe jacking well 100, and the staff controls the maintenance valve 310 and the intake and exhaust valve 210 through the operation platform 400 to work. The top of the operating platform 400 is provided with a manhole 410 for staff to enter. In order to ensure the safety of the workers going down the well, the top of the operating platform 400 in this embodiment is provided with a guardrail 420 .

The working principle of the utility model is as follows:

When the pipe jacking well 100 is overhauled, the maintenance valve 310 can be opened, the submersible pump can be sunk into the bottom of the drainage pipe 300, and the water in the pipe jacking can be effectively discharged through the pumping of the submersible pump, and the pipe jacking well 100 is a dry well to realize dry-wet separation , there is no need to set another wet well, which greatly reduces the size of the pipe jacking well, reduces the investment cost, and can also balance the air pressure inside the pipe jacking through the intake and exhaust valves 210 .

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments.
