Description
Technical field
The present invention relates to the technical fields such as bridge, bridges and culverts, diversion works, water engineering.
Background technology
Currently, seepage well and pipeline are widely used in the fields such as bridge, bridges and culverts, diversion works, water engineering, however
Some cannot go up excavation, heavy traffic, the construction area that densely populated, above ground structure is numerous and underground utilities are complicated in large area
Domain, how rapid construction, reduction quantities and saving engineering land used are always a technical barrier.
If by reconnoitring engineering geology, hydrological geological conditions, cannot carry out Ground slot operation region,
The construction technology of push pipe fast jacking is taken, the frictional force of seepage well or pipeline and surrounding soil can be reduced, by seepage well or pipeline
It is headed into soil by the gradient of design, rapid construction can be efficiently solved, quantities is reduced, save the construction difficult problems such as engineering land used,
And with economic, efficient, the comprehensive function of environmental protection.
Invention content
Technical problem solved by the invention is to provide a kind of horizontal seepage well or pipeline push pipe quick construction technology, use are non-
It is quick to solve bridge, bridges and culverts, diversion works, the horizontal seepage well in the engineering fields such as water engineering or pipeline for excavation construction mode
The construction difficult problem of jacking.
The technical solution adopted by the present invention is horizontal seepage well or pipeline push pipe rapid constructing method, is included the following steps：
One, jack is connected at designated position erection construction platform, operation platform, push pipe front uses detachable drill bit,
Push pipe includes at least two-stage, and caliber is descending to be set in together, and drill bit is equipped with the connector with push pipes at different levels, each push pipe
It is externally provided with high-pressure water pipe, high-pressure water pipe is communicated in high-pressure hydraulic pump, and high-pressure water pipe is equipped with water jet；
Two, jack starts to start high-pressure hydraulic pump while pushing tow, and high-pressure water pipe high speed sprays mud, and soil layer construction is made to loosen,
And form one layer of lubricating film；
Three, after level-one jacking to designated depth, level-one push pipe is detached with drill bit, be sleeved on two level in level-one push pipe with it is separable
Formula drill bit is connected, and continues jacking forward and then reversely pulls out level-one push pipe to designated depth；
Four, two level push pipe is detached with drill bit, and the three-level push pipe being sleeved in two level push pipe is connected with drill bit, continues jacking forward extremely
Then designated depth reversely pulls out two level push pipe；
Five, the operation of step 4 is repeated, until afterbody push pipe reaches designated depth.
Water jet in high-pressure water pipe is strip crevice or hole.
Afterbody push pipe uses floral tube, ensures that water is penetrated into, flowed into.
The beneficial effects of the invention are as follows a kind of horizontal seepage well of offer or pipeline push pipe quick construction technologies, realize bridge, bridge
In the engineering fields such as culvert, diversion works, water engineering, ground is not excavated, is not removed, is not destroyed above ground structure, do not destroy ring
The construction effect for the push pipe fast jacking that border, the segment difference for not influencing pipeline deform.

Specific implementation mode
1. horizontal seepage well or pipeline push pipe rapid constructing method, include the following steps：It is flat in designated position erection construction
Platform connects jack at operation platform, and push pipe front uses detachable drill bit,
One, jack is connected at designated position erection construction platform, operation platform, push pipe front uses detachable drill bit
15, bit diameter is set according to the diameter of push pipe.As shown in Figure 1, can construct in open caisson, design position sets up dimension in well
Stair 1, maintenance platform 2 and operating platform 5 are repaiied, after the completion of setting up, jack is installed on operating platform 5, push pipe bearing etc. is set
It applies；
Push pipe includes several grades, and caliber is descending to be set in together, and drill bit 15 is equipped with the connector with push pipes at different levels,
Each push pipe 4 high-pressure water pipes 8 of outside weldings, high-pressure water pipe 8 are connected to always at drill bit 15, are dug in high-pressure water pipe 8
Gap or hole 9, high-pressure water pipe 8 are communicated in high-pressure hydraulic pump, and it is high material injection will to be sprayed in high pressure pond by high-pressure hydraulic pump
Pressure pipe 8, water or mud may be selected in injection material in high pressure pond.High-pressure water pipe is sequentially connected, and is continuously connected to high-pressure pump
It stands；
Two, jack starts to start high-pressure hydraulic pump while pushing tow, and high-pressure water pipe 8 sprays at a high speed mud or water, makes original soil layer
Connection loosing, and one layer of mud is formed as lubricating film, reduce the side friction during pushing tow.
Three, using the scheme of classification jacking, after level-one jacking to designated depth, level-one push pipe 10 and drill bit during pushing tow
15 separation, the two level push pipe 11 being sleeved in level-one push pipe 10 are connected with detachable drill bit 15, continue jacking forward and extremely refer to
Then depthkeeping degree reversely pulls out level-one push pipe 10；
Four, two level push pipe 11 is detached with drill bit 15, and the three-level push pipe 12 being sleeved in two level push pipe 11 is connected with drill bit 15, is continued
Forward then jacking reversely pulls out two level push pipe 11 to designated depth；
Five, the operation of step 4 is repeated, until afterbody push pipe reaches designated depth.
Several push pipes of jacking are classified, afterbody push pipe is only the final goal of this time construction.According to construction environment and
Pipeline applications can make afterbody push pipe different designs, such as construction final purpose is structure seepage well, then last
Grade push pipe uses floral tube, ensures that water is penetrated into, flowed into.
