Description
Technical field
The present invention relates to trenchless prop pipelining field, especially a kind of construction method of non-horizontal push pipe.
Background technique
Jacking construction is exactly a kind of construction method that pipeline is laid with using no-dig technique mode, i.e., in the active well of pipe design
It is interior to use artificial or pipe jacking tunnelling machine head transverse direction mine working；Using jack by the piecewise jacking of pipeline, and driving is discharged
Dregs outward transport, is completed until push pipe is laid with.This method efficiently solve in piping laying construction to the destruction of inhering architecture and
The problems such as blocking that traffic route is formed, creates the fine environment an of civilized construction for urban construction.
General pipe-jacking project is mostly the push pipe of horizontal push pipe or slope very little, and the push pipe of small slope can be pushed up by adjustment
The orientation of pipe die carries out pushing tow, however, the offset distance adjustment radian of push pipe head is then when to carry out big slope push pipe
It is limited by the rigidity of the pipe of pipeline and the connection type of pipe；When the rigidity of pipeline is bigger, offset adjustment amount is then smaller.Such as steel pipe
Jacking construction just seriously receive push pipe head offset distance adjustment radian limitation, therefore, by adjustment push pipe head take
It is difficult to realize to the pipeline laying for carrying out larger slope.When solving push pipe pipeline beginning and the big drop of terminal in Practical Project
It can be realized by adjusting the top mouth of pipe elevation and receiving port elevation of upper pipe working well.But in some special circumstances, push pipe work
It cannot achieve the adjustment of top mouth of pipe elevation and receiving port elevation as well, the piping work of big drop can only often use open cut pipe laying
It solves, time-consuming, laborious and influence surrounding enviroment.
The construction of push pipe is carried out in the active well (starting well) of push pipe, and conventional push pipe starting well bottom plate is usual
Built into it is horizontal, so as to jacking construction equipment arrangement and tube coupling placement；Push pipe back seat is built into perpendicular to starting well
Bottom plate, so that push pipe group jack provides horizontally-supported counter-force.In some special circumstances, jacking construction need to be laid with slope
When biggish pipeline, conventional push pipe starting well construction is difficult to meet construction requirement, needs to carry out the innovation of technology.
Summary of the invention
The purpose of the present invention is to provide a kind of construction method of non-horizontal push pipe, and it is suitable for the push pipes of big slope.
The solution that the present invention solves its technical problem is: a kind of construction method of non-horizontal push pipe, including following step
Suddenly,
1) it is originated on the borehole wall intend building, by design altitude and the pre-buried guide pipe of push pipe slope；
2) on the bottom plate of starting well, guide base identical with push pipe slope is built, is disposed with push pipe on guide base
Guide rail used；
3) wedge-shaped backrest is built in the push pipe back seat inner surface of starting well, the one side of wedge-shaped backrest is close to push pipe back seat
Medial surface, the one side in wedge-shaped backrest far from push pipe back seat are vertical with the working face of guide base；
4) jack group is connect by rear end potential dividing ring with wedge-shaped backrest；
5) when push pipe operation, tube coupling to be hung on the guide rail of guide base, the front end of tube coupling is docked with by the tube head of push pipe,
The rear end of tube coupling is connect by front end potential dividing ring with the actuating station of jack group, after ready, implements push pipe work.
As a further improvement of the above technical scheme, the push pipe slope is defined as k, 0.087 k≤1 <.
As a further improvement of the above technical scheme, the working face of the guide base and the angle of horizontal plane are α, 5 °
α≤45 ° <.
As a further improvement of the above technical scheme, the guide base and wedge-shaped backrest use steel construction or concrete
Structure fabrication.
As a further improvement of the above technical scheme, wedge-shaped backrest and push pipe back seat are by being rigidly connected into a stress
It is whole.
The beneficial effects of the present invention are: the present invention is oriented to base by building guide base and wedge-shaped backrest in starting well
The working face of seat matches with push pipe slope, and the actuating station of jack group releases tube coupling, tube coupling along push pipe slope into hole, reality
Existing non-horizontal, big slope jacking construction.Push pipe slope range in the present invention be (0.087,1], can not be in existing level
It is realized in push pipe.
