Abstract
The utility model discloses a horizontal directional drilling emergency rescue device which aims to improve the safety and the efficiency of horizontal directional drilling crossing and dragging emergency rescue. The horizontal directional drilling emergency rescue device is characterized in that steel strands are connected with a dragged pipeline and hydraulic piecing jacks, cables are anchored by jack anchoring heads, the jack anchoring heads are connected with cable sleeves sleeved on an anchoring steel pipe, the jacks are driven by hydraulic systems to continuously drag the steel strands, and the dragged pipeline can be drawn out of a horizontally directionally drilled hole, so that horizontal directional drilling emergency rescue operation can be completed. The horizontal directional drilling emergency rescue device has the advantages that the clamped pipeline can be safely and efficiently dragged out of the hole, a ground anchor facility is simple and convenient and is high in anchoring force, the steel strands are low in stored energy and traction deformation, do not rebound after being broken and high in pipeline emergency rescue safety performance, the continuity and the speediness of the emergency rescue operation can be guaranteed under the traction effects of the jacks, angles of the steel strands can be circularly and freely adjusted in all directions, the dragged pipeline, the jacks and a ground anchor can be positioned on the same straight line, and accordingly resultant force of the piecing jacks can be increased to the greatest extent.
Description
Technical field
The utility model relates to a kind of horizontal directional drill emergency device, belongs to non-excavation pipeline construction technology field.
Background technology
In long distance pipeline construction, horizontal directional drill has become the Main Means of laying non-excavation pipeline.At Directional Drilling, pass through back in the process of dragging, due to reasons such as collapse hole and complicated geologies, be prone to because pull-back force increases bit freezing or the drill rod breaking causing, cause back dragging unsuccessfully.Whenever now, general employing pulley cohort returns to drag speedily carries out rescue work, but drag for every time 3～5 meters just to need to change assembly pulley, cause the inefficiency of speedily carrying out rescue work, do not meet the timeliness demand of speedily carrying out rescue work, and, the wire rope two ends of pulley cohort are fixed, its increase with pulling force produces deformation, once fracture can form fatal threat to Field Force.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal directional drill emergency device, and it has safe, simple and efficient feature.
The technology contents of this horizontal directional drill emergency device is as follows:
The flange of this emergency device connect be positioned at horizontal directional drill hole gone back to hauling pipe road; Steel strand are divided into multiply, and one end is individually fixed in flange hole uniform on flange, and the other end is all clamped in each corresponding hydraulic pressure punching jack; Each hydraulic pressure punching jack all connects on the base that each is corresponding, rest on the ground, and each jack front end all connects jack anchorage head; Each corresponding cable of the equal anchoring of each jack anchorage head, each cable front end all connects each corresponding cable cover, and each cable cover is all sleeved on the anchoring steel pipe that is positioned at earth anchor foundation ditch, and the load side of earth anchor foundation ditch is rammed steel sheet pile.
This emergency device can return hauling-out hole efficiently by the pipe safety being blocked, and earth anchor facility is simple, convenient and anchored force is large, can greatly reduce the stand-by period that conventional concrete earth anchor needs curing conservation, fully meets engineering actual demand.This emergency device adopt that energy storage is little, traction deflection is little and the steel strand that do not rebound of having no progeny as traction piece, can greatly improve the speedily carry out rescue work safety of operation of pipeline; With jack, draw steel strand, needn't repeatedly be wound around assembly pulley, can guarantee pipeline speedily carry out rescue work continuity and the rapidity of operation; Steel strand can 360 ° of comprehensive free adjustment angles, can make to be returned hauling pipe road, jack and earth anchor on same straight line, farthest increase making a concerted effort of punching jack.
Accompanying drawing explanation
Fig. 1 is horizontal directional drill emergency device structural representation.
Fig. 2 is horizontal directional drill emergency device top view.
The specific embodiment
Embodiment:
With reference to Fig. 1 and 2, embodiment of the present utility model is further illustrated:
This emergency device comprises flange 1, snap close 2, steel strand 3, hydraulic pressure punching jack 4, base 5, jack anchorage head 6, cable 7, cable cover 8, earth anchor foundation ditch 9, anchoring steel pipe 10 and steel sheet pile 11:
The application process of this emergency device is as follows:
1) Farm Planning: place cleaning, press construction requirement excavation earth anchor foundation ditch 9 and cable channel 12;
2) equipment is installed:
A., anchoring means is installed: with rammer, steel sheet pile 11 is rammed to earth anchor foundation ditch 9 load sides, with hanging device, the anchoring steel pipe 10 that puts cable cover 8 is put into earth anchor foundation ditch 9;
B. welded flange: the pipe end that will be gone back to hauling pipe road 13 welds with flange 1;
C., punching jack is installed: three hydraulic pressure punching jack 4 use bolts are separately fixed on three bases 5 that are positioned on ground 15, the center line of the base 5 in the middle of being positioned at is aimed at and returned hauling pipe Dao13 center extended line;
D., steel strand are installed: 24 steel strand 3 are divided into San Gu， one end respectively through uniform flange hole on flange 1, and fixing with snap close 2, the other end is clipped in respectively separately in corresponding hydraulic pressure punching jack 4;
E., anchored end cable wire is installed: at each hydraulic pressure punching jack 4 front ends, all weld jack anchorage head 6, at each anchorage head front end, all weld cable 7, at each cable 7 front ends, all by Special lock catch, connect cable cover 8, make to be added in the pulling force being returned on hauling pipe road 13 and pass to anchoring steel pipe 10 through cable 7, and born by steel sheet pile 11 and earth anchor foundation ditch 9.
3) start the equipment of speedily carrying out rescue work: primer fluid pressing system, drive three hydraulic pressure punching jack 4 continuous drawing steel strand 3 that add up to 600 tons, will be gone back to hauling pipe road 13 and be pulled out horizontal directional drill hole 14, thereby be completed the horizontal directional drill operation of speedily carrying out rescue work.
