Description
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 larger, can't or be difficult in the situation of fluting, usually adopting at present construction by pipeline jacking method.A kind of tunneling formula method of construction that pipe jacking method adopts when being the various obstacles such as under ground piping railroad crossing, road, river or building, during construction, press the work mine pit as starting point take ready top first, 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 simultaneously and transport the earth in pipe front.After the first pipe joint all heads into soil layer, then the second pipe joint is connected on the back and continues jacking, as long as the resistance that produces when the top power of jack is 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 larger during construction, and construction cost is high.
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 in guide channel fixing 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, there is the flange-like interface rear portion of dummy pipe and the front portion of rear tube, casing inner diameter is than the required diameter large 1/5～1/3 that penetrates engineering pipeline, sleeve pipe divides anterior cannula and rear sleeve two-part, between anterior cannula and the rear sleeve by being welded and fixed, the front portion of anterior cannula also is welded and fixed taper sheath, and the taper sheath top has the hole of reeving.
During the top conduit, with pressing device first 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, the flange-like interface of again rear tube being connected with dummy pipe connects with bolt, then jacking rear tube is until dummy pipe ends when passing in the another side guide channel.
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 with wire rope, start winch pulling dummy pipe, continue the jacking rear tube with pressing device simultaneously, until end when just also not heading into the stratum in the hole of reeving at rear tube rear portion.
When helping pull a cart pipe, wire rope is penetrated respectively the hole of reeving at reeve hole and the taper sheath top at rear tube rear portion, with this conduit is connected with sleeve pipe, start winch pulling dummy pipe, use simultaneously pressing device jacking rear sleeve, until anterior cannula is ended when passing in the another side guide channel.
The trombone slide installation method of described bypass pipeline is characterized in that: during the conduit of top, pressing device is selected 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 the purpose of protection Adjacent Buildings 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 affect surrounding building, save a large amount of shoveling expenses with routine fluting pipe laying method phase specific energy, 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, construction cost is low, short construction period, and installation quality is high, and manufacturing efficiency is high.
