What are pipe jacking working wells and receiving wells

Pipe jacking construction is an underground pipeline construction method developed after shield construction, which does not need to excavate the surface layer, and can cross roads, railways, rivers, surface buildings, underground structures and various underground pipelines. Pipe jacking construction is carried out with the help of the main jacking cylinder.

and the thrust between the pipes and the relay room, etc., to push the tool pipe or roadheader from the working shaft through the soil layer to the receiving shaft and lift it. At the same time, the pipeline immediately behind the tool pipe or the roadheader is buried between the two wells, in order to realize the construction method of trenchless laying of underground pipelines.

The working well is the caisson where pipe jacking equipment is installed and jacked.

The receiving well is the well from which the pipe on top leads through.

Pipe jacking: jacking into the well is commonly known as the working well, high strength after jacking into the wall at both ends, the receiving well as the name suggests is used to receive the working well pipe, the wall is thin, add a point (where the construction process of pipe jacking is used, the underground must not be able to do large excavation treatment, the working well and the receiving well are generally located in the position of the inspection well, which is convenient for the next process construction to reduce the cost, and the strength of the pipe jacking pipe is not up to the requirements of long-distance jacking, so the middle section needs to be jacked at both ends of the receiving well. It is enough to understand it from all sides.

The working well is the caisson where pipe jacking equipment is installed and jacked. The receiving well is the well from which the pipe on top leads through.

Don't you actually need to set up a receiving well? After the steel sheet pile is supported, the drill bit comes out and the pipe comes out, and it is directly made into a brick inspection well. I don't know if it's possible.

Can a professional come in to answer, has the construction unit done it, sometimes the pipe jacking is not that it cannot be dug large, but that there is a building or other in a certain lot.

The launch shaft is the place where all the jacking equipment is installed during the pipe jacking construction, and it is also the starting place of the pipe jacking machine. Therefore, the pipe jacking construction must have a starting well Zen bird cherry, see figure.

Pipe jacking aid recovery shaft is a kind of mine ventilation, drainage and rescue facilities, mainly used to solve the situation of underground gas, water hazards, accidents and other situations in coal mines. The role of pipe jacking and recovery well mainly includes the following aspects:

1.Ventilation: The pipe jacking aid recovery well can be connected to the underground roadway through the wellhead to achieve top ventilation and ensure the safety of underground workers.

2.Drainage: The pipe jacking aid recovery well can pump out the underground water, mud and other substances through the underground pumping station to ensure the smooth flow of the underground roadway and prevent water accidents.

3.Rescue: The pipe jacking aid recovery well can be used as a rescue channel to provide underground emergency rescue and material transportation to ensure the life safety of underground workers.

4.Monitoring: Gas detectors, thermometers, pressure gauges and other monitoring equipment can also be installed in the pipe jacking aid recovery well to monitor the underground tile bend, temperature, pressure and other indicators in real time, so as to grasp the downhole situation in time and prevent the occurrence of downhole accidents.

In general, pipe jacking is an important coal mine safety facility, which can effectively ensure the safety and production of underground workers and prevent accidents.

The pipe jacking receiving shaft is an important facility for drilling coalbed methane wells in coal mines, which mainly plays the role of collection, separation and purification. When drilling coalbed methane wells, pipe jacking receiving wells need to be built at the top of the coal seam, and the pipe jacking receiving wells are connected with the coal seam wells through pipe jacking, so as to achieve the effect of greatly increasing the recovery rate of coalbed methane. The pipe jacking receiving well can collect and process the coalbed methane, coalbed water and coal seam oil produced in the coal seam, which can well avoid polluting the coal mine environment and improve the recovery efficiency of coalbed methane.

At the same time, it can also reduce the workload of the ground hail foundation and the service life of the equipment.

Summary. The general term for the top of the receiving well in pipe jacking work can be "rod distance", that is, the pipeline of pipe jacking crosses other pipelines parallel to it laterally during the construction process, and the longitudinal distance between the pipe jacking pipeline and other pipelines is called "rod distance". After determining the rod distance between the pipe jacking pipeline and other pipelines, the buried depth and inclination angle of the pipe jacking pipeline can be calculated, so as to ensure the safe and smooth progress of pipe jacking construction.

Excuse me, but please go into more detail?

Hello friends, the receiving well before pipe jacking must be sold. The receiving well before pipe jacking is an important treatment method to change the original structure of the pipeline to the new structure. It is mainly composed of a set of pipe joints, transition pieces, etc., which can directly connect the pipe jacking to the loose silver in the pipeline.

In some cases, the receiving well can play a role in regulating the distribution of the flow rate, and can also facilitate later maintenance and inspection. I hope mine can help you<>

Summary. Pipe jacking before the receiving well must be done, pro, the meaning of this question is not clear, if the top to the river or to the original inspection well position, you can also top to the next working well can not be used to receive the well.

Do you have to do the receiving well before pipe jacking, dear, the meaning of this question is not clear, if you go to the river or top to the original inspection well position, you can also go to the next work to eliminate the Zheng well without receiving the well. Blind hood.

Is the receiving well necessary to be completed before pipe jacking?

Is the receiving well a must be completed before pipe jacking, yes, which is this relevant specification.

What work materials are needed before pipe jacking.

1. The reinforced concrete pipe includes the application form, hidden inspection, jacking as far as possible and the inspection batch can be, 2. The construction of the blind pipe next to the top is a trenchless construction method, which is a kind of pipeline burial construction technology that does not excavate or excavates less dust. The construction of pipe jacking method is to overcome the friction between the pipeline and the surrounding soil with the help of the jacking equipment generated by the jacking equipment in the working pit, jack the pipeline into the soil according to the designed slope, and transport the earthwork away. After the first section of the pipe is completed and the soil layer is jacked, the second section of the pipe brother Junzi continues to jack.

The principle is to use the thrust of the main top cylinder, the pipeline, the relay room, etc., to advance the tool pipe or roadheader from the working pit through the soil layer to the receiving pit and lift it. The pipe is buried between two pits immediately after the tool pipe or TBM.

Summary. Hello <>

The receiving well before pipe jacking is a must.

Is it necessary to do a receiving well before pipe jacking?

Hello <>

The receiving well before pipe jacking is a must.

The receiving well is mainly used to check whether the basic conditions and underground pipeline layout of the roof next pipe before construction meet the requirements of the specification, so as to ensure that the pipe jacking can operate safely and stably after construction. In the receiving well, the dust also needs to carry out relevant tests and measurements, such as hydraulic pressure test, geological exploration, buried depth detection, etc., in order to determine the specific plan of pipe jacking construction.

The pipe jacking working well is set upstream.

The pipe jacking working well is set upstream. The installation location of the pipe jacking well mainly depends on the nature of the pipeline conveying medium and the design requirements of the pipeline. Under normal circumstances, the pipe jacking well should be installed in the upstream position of the transmission pipeline, so that the use effect and convenience of the pipe jacking well can be fully guaranteed.

Because the purpose of pipe jacking is to control pipeline leakage, detect pipeline leakage, minimize environmental pollution, and detect the abnormal situation at the discharge port in time and deal with it as soon as possible. In the case of upstream locations, the pipeline can be monitored close to the control point, which can react more quickly, thus effectively reducing losses. In addition, the effect of installation in the downstream location to prevent the spread of leakage and reduce pollution is weaker than that of the upstream.

In the process of pipe jacking construction, the internal equipment of the dual-purpose pipe jacking machine working pit and the receiving pit, such as the pipe jacking machine and the oil pumping station, must be strictly in accordance with the design requirements to stop the device, maintenance and maintenance, the construction personnel in the use of the pipe jacking machine, to often check the operation of the machine, in the pipe jacking process can encounter obstacles, if an accident occurs, they should be dealt with immediately.
