Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment only instrument is a part of embodiment of the invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of protection of the invention is belonged to.
Refer in Fig. 1~4, the embodiment of the present invention, a kind of minimally invasive small-bore pipe-jacking project construction method excavates work first
Well and each one of received well, then horizontal directional drilling machine is mounted in active well, specific implementation is from active well to received well
Carry out, implementation steps include laser guide, return and drag drilling, return and drag borehole cleaning, the road master operation composition of jacking construction four.
The laser guide：First rig is positioned in active well, then the laser-guided systems of independent research, institute are progressively installed
Stating laser-guided systems includes total powerstation 1, starter 2, guide rod 3, display screen 4, light target 5 and support 6, swashs
The installation and debugging of light directing system are completed, and the laser that total powerstation 1 is sent is projected on display screen 4, controlled by light target 5
System is oriented to jacking direction；When being oriented to construction, guide rod 3 is promoted to creep into by rig, the laser light indicated according to display screen 4
Point position, the advance side of adjustment guide rod 3 is reached by being rotatably connected on the direction of the front end starter 2 of guide rod 3
To, it is ensured that guide rod 3 reaches received well position in a predetermined direction, and the final deviation of guide rod 3 is no more than ± 3cm.
Drag drilling described time：Drilling tool heads are installed on the guide rod 3 at received well position and (carry cone bucket type guide head
Towed equipment), returned in active well along guide direction when rotating and drag drilling tool heads, returned earthwork when dragging in hole and cut
Cut and smash, and be fabricated to the sposh of half flow regime；Return and drag drilling tool heads to return afterbody when dragging need to reserve jointed rod.
Drag borehole cleaning described time：Reserving to install back on drilling rod at received well position after the completion of drilling drags borehole cleaning ball (to carry centralizer
Return support Counterboring apparatus), return when rotating along guide direction in active well and drag borehole cleaning ball, mud is by rig during time dragging
It is conveyed into back by guide rod 3 and drags borehole cleaning ball, then constantly sprays into from borehole cleaning ball to surrounding hole wall the bentonite slurry of modulation.
The bentonite slurry of penetrating and return drag borehole cleaning ball collective effect, the soil body in duct is constantly stirred first, the soil body is become more
It is dilute it is thick be easy to flowing；Secondly, the hole wall periphery soil body is extruded so that the hole wall periphery soil body has more stablized retaining wall effect.
Simultaneously because the lubrication of bentonite slurry in itself, is that next step jacking pipeline plays lubrication and retaining wall effect
The jacking construction：Return after the completion of dragging borehole cleaning, the drilling equipment Removal on horizontal directional drilling machine be subjected to push pipe operation,
Must be in tubing front end installation tool head tube cap during push pipe.
The characteristics of present invention has that construction speed is fast, it is small to be influenceed on surrounding enviroment, only excavated on a small quantity to original ground, relies on
It uses high-performance mechanical technology and advanced construction technology, the φ 400- φ 800 municipal drainage pipe below 3 meters of buried depth
Carried out in road engineering it is a number of use, this engineering method construction cost is moderate, and the use low engineering cost in full of constructing is in urban road
Pipe laying construction use construction costs in full is excavated, construction quality is secure, is presented preferably in the construction of municipal public use underground pipe network
Economic benefit.
The present invention carries out construction effects of energy saving and emission reduction substantially using novel high-performance machinery, and the bentonite slurry of construction injection is nothing
The material of poison, depending on mud pit, pulping amount are not provided with the construction field (site) according to usage amount, the mixing shape soil ejected during push pipe is
Sposh, construction site is transported after the final desiccation of sposh, rather than mud is transported, and reduces environmental pollution.Construction area area is small,
Construction noise is small, the pressure that passed through to social passage is considerably reduced compared with excavating pipe laying, reduces construction noise, does not almost have
There is airborne dust, the work especially in region constructions such as urban road, limited construction site, underground utilities complexity and environmental requirement height
Effect is obvious, there is good social benefit.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and do not carrying on the back
In the case of spirit or essential attributes from the present invention, the present invention can be realized in other specific forms.Therefore, no matter from
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only included
One independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should be by
Specification is as an entirety, and the technical solutions in the various embodiments may also be suitably combined, and forming those skilled in the art can
