Abstract
The present invention relates to a tunnel class, more specifically to a counter pulling method used in underground pipe culvert linear hidden digging. By using the method of counter pulling two heads on both ends of a pipe culvert to be dug in a hidden digging way and pipe culvert segments respectively connected in the back side of the heads, the heads on both sides and the standard pipe culvert segments continuously move forward in pairs in opposite directions along the axial direction until a butt joint is completed. The present invention has the advantages that the present invention can be suitable for more engineering situations because the two heads counter move through balanced pulling force with no need of recoil force provided by a starting well, and a collateral resistance range and digging power are both halved because the working surface always maintains balanced soil pressure and only small dynamic friction force needs to be overcome for continuous propulsion; besides, the present invention also has the advantages of high digging speed, improved work efficiency, reduced apparatus investment and reduced occupied space for apparatus.
Description
Technical field
The present invention relates to tunnel-like, relate to concretely a kind of be used for underground pipe culvert linear dark digging to pulling method.
Background technology
The tunneling of buried pipe of the prior art, culvert normally at one end is provided with received well, the other end is provided with Starting Well, big stroke jack group is set in Starting Well, the stroke of this jack group is consistent with standard pipe culvert pipe joint usually, need to do the recoil in the Starting Well and reinforce, to provide jacking the omnidistance needed power of sentencing the accuser to the punishment facing the person he falsely accused.During construction, utilize the thrust of jack group, head (the positive soil pressure effect of soil, guiding and balance of cutting is arranged) and standard pipe culvert pipe joint are thereafter ejected Starting Well, enter the stratum, the jack group that bounces back then adds follow-up standard pipe culvert pipe joint, ejects again, circulation enters received well until head, pipe culvert tube coupling so one by one.The shortcoming of this tunneling method is: Starting Well need be done the recoil and reinforce; Need big stroke jack group; Shrinking back the jack group when placing follow-up pipe culvert tube coupling, and work plane has the anxiety of the earth pressure balance of losing, and easily causes the ground surface sedimentation; The collateral resistance scope is big, is interrupted to advance, and need overcome bigger stiction; Jack-in process needs accurately guiding, can guarantee that just tube coupling enters received well.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, provide a kind of be applicable to short-distance and medium-distance, be used for underground pipe culvert linear dark digging to pulling method, this method adopts drawing two heads that are positioned at the two ends of desiring tunneling pipe, culvert to reach the method for the pipe culvert tube coupling after being connected separately, the head that makes both sides and standard pipe culvert pipe joint along axis direction continuously, in pairs, march forward are mutually finished until butt joint.
The object of the invention realizes being finished by following technical scheme:
A kind of be used for underground pipe culvert linear dark digging to pulling method, adopt following steps: at first one Starting Well respectively is set at the two ends of tunneling pipe culvert; Bore technology with orientation, prolong the engineering axis direction, between the Starting Well at two ends, execute and draw the cable wire group; Connect head (cutting the positive soil pressure effect of soil, guiding and balance) respectively at the two ends of cable wire group, wherein the cable wire group cooperates with head is movable, have at least an end to adopt punching jack and incidental cable wire self-locking device on each root cable wire, save at the head back at two ends tube connector culvert pipe power to be provided and to realize spacingly; The unidirectional continuous pulling force that utilizes the reciprocating motion of jack to produce to the cable wire group, with the both sides head and the pipe culvert tube coupling after being connected continuously, in pairs, in opposite directions to drawing in into the stratum, wherein utilize Starting Well to be unearthed; After the both sides head is met and discussed, utilize default structure, finish butt joint.
Have at least an end to adopt punching jack and incidental cable wire self-locking device on each above-mentioned root cable wire power to be provided and to realize spacing, can refer to wherein has an end to adopt punching jack and cable wire self-locking device power to be provided and to realize spacingly, and it is spacing that the other end adopts the cable wire anchor head to realize; Also can be all to adopt punching jack and cable wire self-locking device at two ends power to be provided and to realize spacing.
Above-mentioned jack group can be selected short stroke jack group for use.
Above-mentioned cable wire self-locking device is to utilize to carve the self-lock mechanism of arranging before and after the type moveable anchor group, the reciprocating motion of jack is become the one-way movement of cable wire.
Advantage of the present invention is, two heads march forward mutually, and tension equalizer need not provide the power of sentencing the accuser to the punishment facing the person he falsely accused by Starting Well, can adapt to more project situation; Cable wire tension elastic deformation, jack reach the continuous operation of subsidiary cable wire self-locking device, make work plane remain earth pressure balance, and propelling only need overcome less kinetic force of friction continuously; Owing to be that the two sides is tunneled simultaneously, collateral resistance scope and driving power are all reduced by half, and two work planes and two unearthed spaces, driving speed is accelerated; The existence of drawing cable wire is also helped straight line driving guiding; Owing to adopted the cable wire self-locking device, replace the interruption work of big stroke jack group with the continuous operation of short stroke jack group, improved operating efficiency, reduced the equipment input, reduced equipment occupation space.
