Description
Technical field
The utility model belongs to natural gas transmission field of engineering technology.In particular it relates to a kind of pair of Gas Exploitation And Transmission station
Underground piping carry out leakage situation detection window.
Background technique
Gas Exploitation And Transmission station is the general name for the various operation posts established for pipeline natural gas or oil field gas.
Its major function is to receive natural gas, be pressurized to pipe natural gas, point defeated natural gas, distribution, gas storage and peak-shaving, sending and receiving clearly
Pipe device etc..During the construction of natural gas fields, in order to save aboveground space, defeated station using more wells the defeated work of next part is largely adopted
Skill causes underground process pipelines numerous, and various pipeline pressures, fluid properties, effect are different.In the actual production process,
It is most of to adopt defeated station using cement for hardened ground.Underground piping is possible to be corroded by the use of many years, leaks.
After underground piping leaks, due to hardened ground, natural gas leaking will not be found in time, sometimes can also be along hardened cement
Floor space conflux channels to oozes out ground just now farther awayly, cannot find leakage situation in time, so that security risk occur.
Utility model content
The purpose of this utility model is that: after leaking for the pipeline adopted under defeated station hardened ground, existing cannot
In time the problem of discovery leakage situation, a kind of Gas Exploitation And Transmission station underground piping leak detection window is provided.The detection window energy
Enough discovery leakage situations in time, to avoid that security risk occurs.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of Gas Exploitation And Transmission station underground piping leak detection window, including detection pipes and capping；Detection pipes are through hardening
The lower section of hardened ground is interconnected by ground with top；It covers and is detachably connected with the top of detection pipes, by hardened ground
Lower section and top are interconnected or close.When the natural gas line under hardened ground leaks, this programme can make leakage
Natural gas is fled and is accumulated in detection pipes.By being detected to the gas in detection pipes, can judge whether there is natural
The case where gas leakage.
Preferably, the top of station interior conduit is arranged in detection pipes.It can be timely detected after pipe leakage,
Be conducive to improve detection efficiency.
Further, detection pipes be arranged at pipeline reducing diameter, at the deflecting or top of infall.Above-mentioned pipeline location is thin
It is weak, it is leaked at first compared to other positions, or the probability for occurring leaking is bigger.
Preferably, the top of detection pipes is higher than the top surface of hardened ground.It can be to avoid following rainy day gas, ground area
Water enters the case where detection pipes.
Preferably, the bottom end of detection pipes is higher than the bottom surface of hardened ground, or flushes with the bottom surface of hardened ground.
It avoids the bottom end of detection pipes from being lower than the bottom surface of hardened ground, makes the natural gas of leakage when the bottom surface of hardened ground is fled, it cannot
Into detection pipes, to the case where there is leakage and can not detecting occur.
Preferably, the top surface of capping is provided with duct size information mark board.Be conducive to Field Force to underground technique
The understanding of pipeline and be familiar with.To be conducive to the visualizing construction in process flow region, help to standardize station construction.
Further, capping is connected with each other with detection pipes by notch.Compared to connection types such as threaded connections, originally
Scheme is on the basis of guaranteeing that capping is completely embedded with detection pipes, the direction that can arbitrarily adjust, to adapt to the pipe of capping top surface
Road information labeling.In addition, notch connection is convenient, be conducive to the operation of Field Force.
Preferably, detection pipes are stainless steel tube, not only contribute to anticorrosion, are prolonged the service life；And it is convenient for
Processing reduces processing cost.
Preferably, it covers as plastics, convenient for processing various marks on the duct size information mark board of capping top surface
Duct size information reduces difficulty of processing.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
Be: when the natural gas line under hardened ground leaks, the utility model can make the natural gas of leakage flee and accumulate in
In detection pipes.The case where by detecting to the gas in detection pipes, natural gas leaking can be judged whether there is.Pass through spy
The method that test tube is detected, convenient for periodically being observed underground piping and being detected, find in time and avoid security risk.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Present embodiment discloses a kind of Gas Exploitation And Transmission station underground piping leak detection windows, as shown in Figure 1, including detection
Pipe 1 and capping 2；Detection pipes 1 run through hardened ground, and the lower section of hardened ground is interconnected with top；Capping 2 and detection pipes 1
Top be detachably connected, the lower section of hardened ground and top are interconnected or are closed.It can will be visited when cement flooring is constructed
Test tube is cast-in-place wherein；The hole of diameter 30mm can also be punched on hardened cement ground with the later period, hole depth is to drill cement floor completely
Face reaches cement and soil interface, detection pipes is mounted in hole, and carry out the sealing between tube wall and cement.
Specifically, as shown in Figure 1, detection pipes 1 be arranged at the top of station interior conduit, especially pipeline reducing diameter, deflecting
Place or infall etc. are also easy to produce the top of leak position.The top of detection pipes 1 is higher than the top surface of hardened ground.The bottom of detection pipes 1
End is higher than the bottom surface of hardened ground, or flushes with the bottom surface of hardened ground.Capping 2 is mutual by notch with detection pipes 1
Connection.The top surface of capping 2 is provided with duct size information mark board, can mark title, caliber and the pipeline rout of various underground pipings,
Such as remove L32, LS23, Φ 219, arrow；The different purposes that various colors mark underground piping can be used, as yellow indicates natural gas
Pipeline, green indicate that water pipeline, black indicate sewage pipeline etc..Detection pipes 1 are process by thin-wall stainless steel.Capping 2 by
Rigid plastics is process.
Periodically the leakage situation of underground piping is detected by detection pipes 1.When detection, capping 2 is opened, by natural
Gas detection instrument can be detected the case where with the presence or absence of leakage.Multiple detection pipes 1 are provided on hardened ground, it can also be by dividing
The concentration that analysis detects unit volume natural gas in each detection pipes 1 is accurately judged to leak point, i.e. concentration more high point is closer to leakage
Point.It was found that leak repairing measure should be implemented after leakage point immediately, to avoid causing danger in time.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
