Description

The trombone slide installation method of bypass pipeline

Technical field

The present invention relates to the pipeline construction method field of metallurgical system, be specially a kind of trombone slide installation method of bypass pipeline.

Background technique

In the pipeline construction engineering, if there is not obstacle can adopt slot grooving, but usually need pass highway, railway, building, river etc. during pipelining, in this case, usually do not allow slot grooving or slot grooving difficulty and drop into all bigger, can't or be difficult under the situation of fluting, adopting construction by pipeline jacking method at present usually.A kind of tunneling formula method of construction that pipe jacking method adopts when being various obstacle such as under ground piping railroad crossing, road, river or building, during construction, be starting point with ready roof pressure work mine pit earlier, after pipe is discharged into working pit, by power transmission top iron and guide track, with the hydraulic jack that is supported on the foundation ditch back seat pipe is pressed in the soil layer, excavates and transport the earth in pipe front simultaneously.After first pipe joint all heads into soil layer, then second pipe joint is connected on the back and continues jacking, as long as the resistance that the top power of jack produced when being enough to overcome push pipe, whole jack-in process repeats with regard to capable of circulation.But construction by pipeline jacking method needs expensive professional equipment, and is subjected to the restriction ratio in place bigger during construction, the construction cost height.

Summary of the invention

In order to overcome the defective of prior art, a kind of, operation simple pipeline construction method few to equipment and place restrictive condition is provided, the invention discloses a kind of trombone slide installation method of bypass pipeline.

The present invention reaches goal of the invention by following technical solution:

A kind of trombone slide installation method of bypass pipeline, carry out successively as follows: pipe alignment → excavation guide channel → making pipeline → top conduit → connect wire rope → pull catheter and wire rope → help pull a cart are managed → are worn the engineering pipe and install, during the excavation guide channel, respectively at the required obstacle both sides excavation guide channel that passes through, and at guide channel internal fixation position limiting pile, wear engineering pipeline and when installing, engineering pipeline passed by guide channel threading on one side and from the another side guide channel, it is characterized in that:

When making pipeline, conduit diameter is 1/5~1/3 of the required engineering pipeline diameter that penetrates, conduit divides dummy pipe and rear tube two-part, the front portion of dummy pipe and the rear portion of rear tube all have the hole of reeving, all there is the flange-like interface rear portion of dummy pipe and the front portion of rear tube, casing inner diameter is bigger by 1/5~1/3 than the required diameter that penetrates engineering pipeline, sleeve pipe divides anterior cannula and rear sleeve two-part, fixing between anterior cannula and the rear sleeve by welding, fixedly taper sheath is also welded in the front portion of anterior cannula, and the taper sheath top has the hole of reeving.

During the top conduit, with roof pressure equipment earlier with under the position limiting pile of dummy pipe in the guide channel to the guide channel jacking of obstacle another side, when just also heading into the stratum, do not end the flange-like interface for the treatment of the dummy pipe rear portion, flange-like interface with rear tube and dummy pipe is connected with bolt again, the jacking rear tube ends when dummy pipe passes in the another side guide channel then.

When connecing wire rope, after dummy pipe passes in the another side guide channel, penetrate wire rope in the hole of reeving of dummy pipe front portion, the wire rope the other end connects winch.

When pull catheter and wire rope, after connecting dummy pipe and winch, start winch pulling dummy pipe, continue the jacking rear tube with roof pressure equipment simultaneously, when the hole of reeving at rear tube rear portion just also heads into the stratum, do not end with wire rope.

When helping pull a cart pipe, wire rope is penetrated the hole of reeving at the reeve hole and the taper sheath top at rear tube rear portion respectively, conduit is connected with sleeve pipe, start winch pulling dummy pipe with this, use roof pressure equipment jacking rear sleeve simultaneously, when anterior cannula passes in the another side guide channel, end.

The trombone slide installation method of described bypass pipeline is characterized in that: during the conduit of top, roof pressure equipment choosing backacter, break point the dead ahead of engineering pipeline to be installed or directly over.

It is that common standard equipment has solved the technical barrier in pipelining highway crossing, railway, building, river and reached protection surrounding buildings thing purpose of safety that the present invention uses.Adopt method of the present invention can finish the installation of one section pipe of passing by on one's way in 6 hours, and do not influence surrounding building, with routine fluting pipe laying method mutually specific energy save a large amount of shoveling expenses, compare with the pipe jacking method of routine, save the expense of using expensive professional equipment.The invention has the beneficial effects as follows: select common standard equipment operation for use, construction cost is low, short construction period, installation quality height, manufacturing efficiency height.
