Abstract
An outgoing anti-deviation device for a large-caliber push bench is characterized in that an anti-rotation devices is included and is symmetrically arranged on the left and the right sides of the tail part of the push bench; the anti-rotation device is provided with U-shaped groove opening; the U-shaped groove opening points to the jacking direction of the axis of the push bench, and is clamped at the tail part of a pipe section; and a plurality of bolts are arranged at the top of the anti-rotation device, and the anti-rotation device is fixed at the tail part of the pipe section through the bolts.
Description
Technical field
The utility model relates to a kind of heavy caliber pipe-jacking machine anti-deviation device of appearing.
Background technique
Under the influence of various factors, deviation on the various directions can be at any time takes place with design route in the track that push pipe advances.Compare with concrete ceiling coil, the steel push pipe is difficult to rectify a deviation more.Because the follow-up tube coupling of steel push pipe is welded on the last joint, all tube couplings form an integral body, do not have the sudden change of corner jumping characteristic between each tube coupling, and therefore along with the increase of jacking distance, the direction of jacking also is not easy to change.Equally, in case the jacking axis produces skew, deflection etc. and the situation that the design axis deviates from, the difficulty of correction of deviation very big.So the initial jacking stage is very important to the control of head attitude, the initial jacking stage does not have deflection, then is not easy deflection in the jack-in process of back yet; If initial jacking stage top is inclined to one side, the back jacking stage will be difficult to correct and come so.Therefore, it is more careful that the steel jacking construction needs, and should in time understand the variation of head attitude and correction in time, avoids taking place excessive deviation.In jacking construction process in the past, there is not ripe anti-deflection technology, the retaining technical measures.
The model utility content
The purpose of this utility model is to provide a kind of heavy caliber pipe-jacking machine anti-deviation device of appearing, and takes place to prevent deflection or to retreat phenomenon.
Be the heavy caliber pipe-jacking machine of the realizing described purpose anti-deviation device of appearing, be characterized in, comprise anti-rotation device, at left and right this anti-rotation device that is symmetrical arranged of push-bench afterbody, this anti-rotation device has the U-groove bevel opening, this U-groove bevel opening points to push-bench axis jacking direction and also is stuck in the tube coupling afterbody, and the top of this anti-rotation device is provided with a plurality of bolts and by these a plurality of tube coupling afterbodys that are bolted to.
Described heavy caliber pipe-jacking machine is appeared and is prevented that deviation device, its further characteristics are, also is included in the saddle weight of the both sides configuration at push-bench head or tube coupling rear.
Described heavy caliber pipe-jacking machine is appeared and is prevented the deviation device, and its further characteristics are also to comprise the anti-stopping device of fixedly connected head or preceding tube coupling.
The beneficial effects of the utility model are:
Set up the empennage anti-rotation device of appearing, a controlling plumbing fixtures hoop attitude preferably at afterbody; When the push pipe fuselage is turned right, the saddle weight on right side is removed to the left side; Otherwise, when the push pipe fuselage turns left, the saddle weight in left side to be removed to the right side, saddle weight can be used to prevent nose drop when push pipe is appeared simultaneously; Even do not annotate thixotropic slurry at the jacking initial stage, the frictional resistance that retreats of push pipe head and former pipe joint joint still can not the positive earth pressure of balance push pipe, before the withdrawal of main top jack, adopt stopping device that head and former pipe joint joint is fixing, can effectively prevent tube coupling and retreat phenomenon.
Description of drawings
Fig. 1 is the tectonic maps of anti-rotation device.
Fig. 2 is the tectonic maps of anti-stopping device.
Embodiment
Push-bench is appeared jacking length in the 40m scope, be controlling plumbing fixtures hoop attitude preferably, as shown in Figure 1, set up the empennage anti-rotation device 100 of appearing at the tube coupling afterbody, anti-rotation device 100 has " U-groove bevel " opening 10, opening 10 points to push-bench jacking axial direction and is stuck in the tube coupling afterbody, anti-rotation device 100 tops are provided with 6 bolts 11 and are used for anti-rotation device is fixed on tube coupling, the channel-section steel 12 that anti-rotation device 100 stretches out is used for the auxiliary rail of device card in the main orbit inboard, and the left and right symmetry of push pipe afterbody is respectively arranged an anti-rotation device 100.
In addition,, carry out the shelf of putting saddle weight in the both sides at push-bench head or tube coupling rear in order to control the normal jacking of push-bench stage hoop attitude, and the balanced saddle weight of placing.When the push pipe fuselage is turned right, the saddle weight on right side is removed to the left side; Otherwise, when the push pipe fuselage turns left, the saddle weight in left side is removed to the right side.This cover saddle weight can be used to prevent nose drop when push pipe is appeared simultaneously.
In addition, the frictional resistance that retreats of push pipe head and former pipe joint joint can not the positive earth pressure of balance push pipe, and this moment, reliable way was to adopt stopping device that head and former pipe joint joint is fixing before the withdrawal of main top jack, prevented tube coupling and retreated phenomenon.
Fig. 2 is the bracket stopping device, the bracket baffle plate 1 long 30cm that heads on wherein, and wide 20cm, the seat board 330 * 30cm of back of the body mountain connecting base 2, the back of the body long 30mm in mountain, being located by connecting 3 is 30 * 30cm.
Stopping device can also adopt the chain block stopping device, chain block is fixed on the front side borehole wall of active well, after a jacking of push pipe is finished, earlier respectively weld a pulling force ring, main top jack can be withdrawn after with chain block tension pulling force ring push pipe being fixed in push pipe bilateral symmetry position.Because the needed retaining power of major diameter push pipe is bigger, hangs the chain block place on the borehole wall of front side and need do consolidation process.
