Description
Technical field
The present invention relates to the technology of underground construction, particularly relate to a kind of technology of top-pulling type construction method of burying box culvert and pipeline underground.
Background technology
Construction by pipeline jacking method has the little advantage of ground interference, is therefore generally adopted when present burying box culvert and pipeline underground construction.But this job practices has following defective: 1) owing to the space of the shared Starting Well of thrustor in the construction by pipeline jacking method is bigger, but also to reserve tube coupling lifting position, therefore the intended diameter of active well is all bigger, larger-diameter upper pipe working well often is subjected to the restriction of site condition and peripheral building and is difficult to be provided with, compliance to narrow and small construction plant is relatively poor, can run in the construction plant of city limitation and can not satisfy the demand that active well section and " back is leaned on " are reinforced the space, perhaps need to drop into big measure expense is taked extremity to contiguous construction of structures transformation or safeguard measure; 2) because the head of pipe jacking tunnelling machine is heavier, therefore construction by pipeline jacking method is prone to the phenomenon that head departs from axis of travel in the soft clay area tunneling process, particularly head goes out, it is particularly evident to have a down dip when going into the hole, make in the tunneling process the head correction and go out, the soil stabilization of going into openings position becomes requisite measure and the operation in the work progress, thereby increased the rectify a deviation input of oil cylinder and the workload and the corresponding expense of soil stabilization of setting up, also reduced the propelling work efficiency, and because of the expansion in culvert section space due to the correction and the disturbance of undisturbed soil, easily cause the increase of ground settlement, thereby bring many environmental safety troubles; 3) because construction by pipeline jacking method only is applicable to the jacking reinforced concrete box culvert and than the steel box culvert of light section, and the flexural strength of steel box culvert often reduces with the increase of its section, easily produce distortion under jacking force and the place ahead head drag effect, therefore the suitability to box culvert material-structure and cross dimensions has certain limitation.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of top-pulling type construction method of burying box culvert and pipeline underground, this method is strong to the compliance of narrow and small construction plant, need not the axial dipole field that extra satisfactory after correcting gets final product STOCHASTIC CONTROL driving head, thereby energy cost saving, raising driving work efficiency, and can prevent soil disturbance, controlling ground settlement, and can be applicable to the box culvert of various material-structures and cross dimensions.
In order to solve the problems of the technologies described above, the top-pulling type construction method of a kind of burying box culvert and pipeline underground provided by the present invention is characterized in that, concrete steps are as follows:
1) build two active wells at pipe culvert design axis two ends, one of them is a Starting Well, and another is a received well;
2) in the head of the Starting Well position of appearing the head device of appearing is installed, and the device of appearing is carried out antiseep handle; Enter the position, hole at the head of received well and head is installed is advanced the hole device, and carry out antiseep and handle advancing the hole device;
3) the drag-line counter force wall is set in received well, and on the drag-line counter force wall, the horizontal pull device is installed;
4) adopt horizontal orientation to creep into hole creating technology and between two active wells, be drilled with a plurality of horizontal orientations hole along being parallel to the burying box culvert and pipeline axis direction, and in each horizontal orientation hole, lay a drag-line, one end of each drag-line is by the locking of the horizontal pull device in the received well, and the other end drags respectively via the horizontal orientation hole and guides to Starting Well;
5) lean on the soil body after the thrustor operating position backside reinforcement in Starting Well, and reserve the operating position of pushing tow back and thrustor;
6) thrustor is installed in Starting Well, and pushing tow back is set at the thrustor rear side;
7) will tunnel head and hang in the Starting Well, and each drag-line axial symmetry will be fixed in driving head front end setting tie point position;
8) will tunnel head and be advanced to the driving initial bit, and strain whole drag-lines;
9) first segment box culvert tube coupling is hung in the Starting Well, and with this box culvert tube coupling and development machine portion's splicing end to end;
10) utilize the horizontal pull device in the received well that the drag-line group is applied pulling force synchronously continuously, utilize thrustor that the box culvert tube coupling afterbody of not holding is applied jacking force simultaneously, the driving head tunnel under the double action of the jacking force of the pulling force of drag-line group and thrustor move ahead, the box culvert tube coupling of not holding is entered in the culvert that is excavated;
11) back one joint box culvert tube coupling is hung in the Starting Well, and the afterbody of this box culvert tube coupling and last joint box culvert tube coupling is spliced, repeating step 10 then, enter desired location in the received well until the front end of first segment box culvert tube coupling.
Further, described thrustor is the jack group, and described horizontal pull device is combined by a plurality of hollow jack that is installed on the drag-line counter force wall, every corresponding hollow jack of drag-line.
Further, by the slight shift that the pulling force of regulating the part drag-line is in time corrected the driving head, tunnel the precision of axially advancing of head with assurance.
Further, during tunneling,, make the mud of institute's pressure injection form the mud cover, to reduce the running resistance of sidewall at each box culvert tube coupling outer wall to each the box culvert tube coupling outer wall pressure injection mud that enters in the culvert that is excavated.
Further, each the box culvert tube coupling outer wall pressure injection cement grout after driving is finished in the culvert that is excavated forms cement paste and solidifies inclusion enclave.
The top-pulling type construction method of burying box culvert and pipeline underground provided by the invention has following beneficial effect:
1) because the driving head tunnels being applied simultaneously by drag-line group and thrustor with joint efforts of moving ahead, and based on pulling force, therefore the jacking force design load is less, thereby the space that thrustor takies in the Starting Well is also less, make the Starting Well diameter satisfying under the single box culvert tube coupling lifting prerequisite and can suitably dwindling, stronger to the compliance of narrow and small construction plant.
2) because having concurrently, the drag-line group provides pulling force and driving head driving guiding function, therefore need not the axial dipole field that extra satisfactory after correcting gets final product STOCHASTIC CONTROL driving head, thereby energy cost saving, raising driving work efficiency, and there is not an increase problem of the culvert section that causes of correction, therefore can prevent soil disturbance, controlling ground settlement.
3) owing to draw the top combined techniques based on pulling force, jacking force is very little, the box culvert traveling process is in tension state, but not squeezed state, distortion be can not produce for the less big section steel box culvert of axial compression resistance distortion moment of flexure, the box culvert, pipeline of various material-structures and cross dimensions or the underground passage of fracture morphology roughly the same therefore can be applicable to.
