Technical field
The utility model relates to the technology of construction machine, particularly relates to the technology of drawing ejection device of a kind of underground buried box culvert or pipeline construction.
Background technology
Pipe jacking method has little advantage is disturbed on ground as a kind of trenchless technology, is therefore generally adopted when present underground pipeline construction.Existing jacking construction device all is made up of pushing tow jack group and driving head, this construction equipment has following defective: 1) the driving power owing to head and tube coupling is provided by the pushing tow jack group in the Starting Well fully, its construction Excavation Length is shorter, and for enough horizontal rear leaning forces can be provided, overcome the jacking resistance, all bigger behind Starting Well structural wall thickness and the Starting Well by reinforcing thickness, be not suitable for narrow and small construction plant; 2) because the driving head is heavier, therefore in the soft clay area tunneling process, be prone to the phenomenon that head departs from axis of travel, particularly head goes out, deviation is particularly evident when going into the hole, make and in time to carry out the correction work of head in the tunneling process, thereby increased the workload and the corresponding expense of correction, reduced the propelling work efficiency; 3) when the iron of adjunction tube coupling top, jacking jack group will be regained, need to prevent that by the stopping device that is arranged in the Starting Well tube coupling from retreating, the operation more complicated, operating efficiency is also lower, in view of original stopping device do not have a retaining power regulatory function, setback force will cause the damage of tube coupling pin-and-hole and even tube coupling when big, thereby lose the retaining effect, and easily cause surface settlement.
The utility model content
At the defective that exists in the above-mentioned prior art, it is strong that technical problem to be solved in the utility model provides a kind of compliance to narrow and small construction plant, the construction Excavation Length is long, and simple to operate, can reduce the correction number of times, improve the ejection device that draws of the underground buried box culvert of driving work efficiency or pipeline construction.
In order to solve the problems of the technologies described above, a kind of underground buried box culvert provided by the utility model or pipeline construction draw ejection device, the design axis two ends of described box culvert or pipeline have two active wells, are respectively Starting Well and received well; It is characterized in that: this device comprises pushing tow jack group, tunnels head, draws in jack group and many drag-lines;
Described pushing tow jack group is installed in the Starting Well;
Be provided with the drag-line counter force wall in the described received well, the described jack group that draws in is installed on the drag-line counter force wall;
Design axis direction along box culvert or pipeline between described two active wells is drilled with at least four horizontal orientation holes that are communicated with two active wells, described each drag-line is layed in respectively in each horizontal orientation hole, the jack group that draws in that one end of every drag-line connects in the received well also locks, and the other end is affixed with the head of driving head;
The described jack group that draws in is provided with the drag-line self-locking mechanism that is used for the drag-line retaining.
Further, the described jack group that draws in is combined by a plurality of short stroke punching jack, the corresponding drag-line of each short stroke punching jack.
Further, described pushing tow jack group is combined by a plurality of long stroke jack.
Further, described box culvert is that square-section or top board are the box culvert of the similar square-section of arch, and described pipeline is the pipeline of circle, oval cross section or similar circular cross-section.
Underground buried box culvert that the utility model provides or pipeline construction draw ejection device, have following beneficial effect:
1) since driving head driving making a concerted effort of moving ahead by drawing in the jack group and pushing tow jack group applies simultaneously, therefore satisfying under the prerequisite that moves ahead with joint efforts, can reduce jacking force and Starting Well, after the horizontal loading that leans on, the back therefore can be less by reinforcing thickness and Starting Well structural thickness, thereby can save Starting Well and back floor space, strengthen compliance narrow and small construction plant by reinforcing;
2) owing to draw in the dual function that the jack group has concurrently provides pulling force and driving head driving guiding, the guiding accuracy of head is improved, thereby can reduce the correction frequency, saves the correction expense, improves the driving work efficiency; And improved greatly by axially being offset to the drawback that the caused culvert section of correction increases, therefore can also effectively prevent to design move ahead section soil disturbance in addition, effectively controlling ground settlement;
3) owing to draw in the jack group and be provided with self-locking mechanism, can provide retaining power, and the big I of retaining power regulates according to the tube coupling Excavation Length, make Starting Well no longer need to be provided with stopping device, not only simple to operate, and improved operating efficiency;
4) owing to draw in jack group and the acting in conjunction of pushing tow jack group, can provide the bigger driving head and the driving power of tube coupling, the construction Excavation Length can be longer.
