Abstract
The present invention relates to a counter pulling device used in underground pipe culvert linear dark digging, which belongs to tunnel classes. The device comprises starting wells, a jack unit, heads, a standard pipe culvert section, a steel cable unit and a steel cable self-locking device, wherein the steel cable unit and the steel cable self-locking device are corresponding to the jack unit; the steel cable unit penetrates through and is connected between the two starting wells; the two heads are respectively connected with both ends of the steel cable unit positioned in the two starting wells. At least one end of each steel cable in the steel cable unit uses a core penetrating jack and an accessary steel cable self-locking device to provide power and spacing. The standard pipe culvert section is connected with the rear part of each of the heads. 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, the working surface always maintains balanced soil pressure due to continuous work of the steel cable, and a lateral resistance range and digging power are both halved because only small dynamic friction force needs to be overcome for continuous propulsion, which is favorable to linear digging guide; besides, the present invention also has the advantages of high digging speed, high work efficiency, less device investment and little occupied space of the device.
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 drawing device.
Background technology
The tunneling device that is used for buried pipe, culvert of the prior art generally includes active well, be received well, Starting Well, and head (cutting the positive soil pressure effect of soil, guiding and balance), standard pipe culvert pipe joint, jack group, wherein the jack group is arranged in the Starting Well, the stroke of this jack group is consistent with standard pipe culvert pipe joint usually, is used for the standard pipe culvert pipe joint of pushing tow with head.The Starting Well rear side need be done the recoil 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 device is: Starting Well need be done the recoil and reinforce; Need to use 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 drawing device, this device adopts drawing two heads that are positioned at the two ends of desiring tunneling pipe, culvert to reach the mode of the standard pipe culvert pipe joint 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 drawing device, comprise active well, the jack group, head, standard pipe culvert pipe joint, this head is cut soil, the positive soil pressure effect of guiding and balance, it is characterized in that also including and corresponding cable wire group of jack group and cable wire self-locking device, described active well is two Starting Wells, wherein the cable wire group connects and is connected between two Starting Wells, two heads are connected to the two ends of the cable wire group that is positioned at two Starting Wells, have at least an end to adopt punching jack and incidental cable wire self-locking device on the every cable wire in the cable wire group, connect standard pipe culvert pipe joint behind the head so that power and spacing to be provided.
Every above-mentioned cable wire have at least an end adopt punching jack and incidental cable wire self-locking device with provide power and spacing can be only at one end to adopt jack and cable wire self-locking device power to be provided and to carry out spacingly, the other end adopts the cable wire anchor head spacing; Also can be all to adopt jack and cable wire self-locking device at two ends power to be provided and to carry out 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.
Above-mentioned head cooperates with the activity of cable wire group.
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; To drawing having of cable wire to be beneficial to 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.
