Description
Technical field
The utility model is related to power cable technical field, specially a kind of no-dig technique push pipe.
Background technology
With the raising and the continuous construction of infrastructure of life of urban resident level, underground engineering construction is increasingly extensive,
And commonly excavate ground laying pipeline construction method and show significant limitation and weak point, the utilization of pipe-jacking technology will be solved
Certainly densely populated, above ground structure is numerous, heavy traffic, the construction difficult problem of underground utilities complex ground.
Pipe-jacking technology is no-dig technique pipe-jacking technology, is the no-dig technique for being used for a municipal construction driving formula pipeline laying construction
Technology, it passes through pipe jacking tool pipe or development machine by the thrust of main top oil cylinder and pipeline enclosure, relay well etc. out of active well
Soil layer under road surface, is advanced in received well always, and stretchy is gone back while propulsion needs the tunnel synchronization laid to advance, and realizes
Non-excavation laying underground piping.Advantage is not influence surrounding environment or influences smaller, and construction site is small, and noise is small.And
Underground job can be goed deep into, this is to excavate the incomparable advantage of pipe laying.But pipe-jacking technology also has a shortcoming, the engineering time compared with
It is long, construction costs height etc..
Pipe-jacking technology in the world has had evolved to very ripe stage, various push pipe methods at present
Occur.But, change ten thousand times without leaving the original aim or stand, what the principle of pipe jacking construction technique was just as.Typically all work perpendicular to the ground well,
Then high pressure hydraulic jack is used, cement or steel pipe underground is headed into, the difference of various technologies is that transport pipeline
The soil inside excavated, the method for the bits such as stone, there is artificial, there is a water odd test, advanced to also have remote control.Existing skill
In art, push pipe required resistance born when heading into bottom is very big, therefore causes push pipe to be easily damaged.
Utility model content
The purpose of this utility model is to provide a kind of no-dig technique push pipe, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of no-dig technique push pipe, including the first cable
Protection pipe and the second cable protection pipe, first cable protection pipe and the second cable protection pipe are staggered, cable protection pipe
Between welded together using thermofussion welding, and dottle pin is set, first cable is protected between adjacent two cable protection pipe outer walls
Pillar and the second cable protection tube cavity are inserted with two first reinforcements parallel with cable protection pipe length direction, and two
First reinforcement is separately positioned on cable protection pipe both sides.
It is preferred that, first cable protection pipe and second cable protection pipe one end are arranged with tapered guide head, the cone
The socket part of shape seeker and cable protection pipe is arranged with the second reinforcement.
It is preferred that, the internal diameter of first cable protection pipe is 150mm, and wall thickness is 12mm；Second cable protection pipe
Internal diameter be 100mm, wall thickness is 8mm；First cable protection pipe and the second cable protection pipe are moulded using modified polypropene
Expect cable duct tube.
It is preferred that, armor is provided between first reinforcement, and the armor is set around cable protection pipe.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model is simple in construction, low manufacture cost, intensity are high, and outer wall endurance is big, and service life is long.
(2) the utility model uses the cable protection pipe for the different-diameter being staggered, and adjacent two cable protection pipes
Dottle pin is set between outer wall, it is possible to increase the integrally-built stability of pipe.
(3) cable protection pipe of the utility model first and second cable protection pipe one end are arranged with tapered guide head, taper
The socket part of seeker and cable protection pipe is arranged with the second reinforcement, using this structure, can reduce push pipe and enter bottom
Needed for the resistance that bears, improve efficiency of construction.
Brief description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is sectional view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of no-dig technique push pipe, including the first cable are protected
The cable protection pipe 2 of pillar 1 and second, the internal diameter of the first cable protection pipe 1 is 150mm, and wall thickness is 12mm；Second cable is protected
The internal diameter of pillar 2 is 100mm, and wall thickness is 8mm；The cable protection pipe 2 of first cable protection pipe 1 and second is using modified poly-
Acrylic plastic cable duct tube, the modified polypropylene plastic cable duct tube of use has superior fire resistance, heat resisting
Energy, resistance to low temperature, can reduce the washing shrinkage of modified polypropylene plastic, improve modified polypropylene plastic dimensional stability, carry
High modified polypropylene plastic rigidity；The cable protection pipe 2 of first cable protection pipe 1 and second is staggered, cable protection pipe
Between welded together using thermofussion welding, and dottle pin is set, first cable is protected between adjacent two cable protection pipe outer walls
The inner chamber of 1 and second cable protection pipe of pillar 2 is inserted with two first reinforcements 3 parallel with cable protection pipe length direction, and
Two the first reinforcement 3 is separately positioned on cable protection pipe both sides；Armor 6, and the armour are provided between first reinforcement 3
Layer 6 is filled to set around cable protection pipe.
In the present embodiment, the first cable protection pipe 1 and the one end of the second cable protection pipe 2 are arranged with tapered guide first 4, described
