Description
Technical field
The utility model relates to hydraulic engineering and construction work scientific domain, especially relates to heavy-caliber base rock boring coring technology in the engineering construction field.
Background technology
The large diameter drilling purposes is very extensive, as engineering drilling, building concrete pile foundation, power station, mine vertical shaft, wastewater treatment well, and oil cellar and extraordinary experimental project boring etc.
Tradition heavy-caliber base rock boring coring equipment work process is: round trip creeps into and finishes, and draws water in the hole, is lowered to the disconnected core of chock wedge, continues to draw water, and uses wire rope colligation core under the operating personnel at the bottom of the hand-hole, and windlass proposes core.The tradition heavy caliber is got core equipment needs the operating personnel frequently to go into the well; because phreatic influence; pumping equipment did not stop when personnel went into the well; it is numerous that the factor of core success is got in influence; as pumping equipment Electrical Safety, wall stability, aperture protection degree, Mechanical Reliability, personnel operation skill level etc. in underground water, the hole in the hole; the probability that personal injury occurs is very big, the security extreme difference.Draw water and need expend the plenty of time, if it is big to run in special formation (abundant as piestic water, big crack the is serious permeable etc.) hole water yield, can't realize drawing water down man-hour, holing just can't go on.
Traditional basement rock large diameter drilling is got core equipment and need be repeated to draw water, and it is low to get core efficient, poor reliability, and safety coefficient is low, and operation easier is big, is difficult to adapt to the needs of large diameter drilling.
The utility model content
The purpose of this utility model is to provide a kind of can get core smoothly by plant equipment under the condition that has water to exist, and gets core efficient height, safety coefficient height, the heavy-caliber base rock boring coring device that reliability is good.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of heavy-caliber base rock boring coring device, comprise joint flange, wire rope, the rope sling hole, guiding coring tube and latch closure, described joint flange and rope sling hole all are positioned at the top of guiding coring tube, the two ends of described wire rope are provided with latch closure, also comprise a piece and a voussoir, one end of described wire rope passes the latch closure of the other end, the wire rope other end forms the bottom that ring-type is arranged at the guiding coring tube, and pass through the fixture colligation on guiding coring tube inwall, described wire rope one end that passes latch closure is arranged on guiding coring tube top after passing the rope sling hole, described voussoir is arranged on the top of guiding coring tube, and a block welding is in guiding coring tube bottom.
Described rope sling hole is two or three, and in the top end face distribution that is centrosymmetric of guiding coring tube, described wire rope is two or three, passes from pairing rope sling hole respectively.
Described piece and voussoir coplane, and be positioned at the two ends of the cross-sectional periphery diameter of guiding coring tube.
Beneficial effect after the employing technique scheme is: heavy-caliber base rock boring coring device of the present utility model neither needs to draw water does not need personnel to go into the well yet, getting core efficient improves greatly, having solved heavy-caliber base rock boring, to repeat repeatedly time of pumping long, the difficulty of drawing water is big, operating personnel's dangerous big technical barrier of going into the well, simple in structure, operation is reliable, gets core success ratio height.
Description of drawings
Fig. 1 be the utility model heavy-caliber base rock boring coring device along the center longitudinal sectional view;
Fig. 2 is the form synoptic diagram of the steel wire loop of the utility model heavy-caliber base rock boring coring device.
Wherein, 1 joint flange, 2 wire rope, 3 rope sling holes, 4 guiding coring tubes, 5 latch closures, 6 voussoirs, 7 pieces, 8 cores, 9 fixtures.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As Fig. 1, shown in 2, heavy-caliber base rock boring coring device of the present utility model, comprise joint flange 1, wire rope 2, rope sling hole 3, guiding coring tube 4 and latch closure 5, joint flange 1 and rope sling hole 3 all are positioned at the top of guiding coring tube 4, the two ends of wire rope 2 are provided with latch closure 5, also comprise a piece 7 and a voussoir 6, one end of wire rope 2 passes the latch closure 5 of the other end, wire rope 2 other ends form the bottom that ring-type is arranged at guiding coring tube 4, and pass through fixture 9 colligations on guiding coring tube 4 inwalls, wire rope 2 one ends that pass latch closure 5 are arranged on guiding coring tube 4 tops after passing rope sling hole 3, voussoir 6 is arranged on the top of guiding coring tube 4, and a piece 7 is welded on guiding coring tube 4 bottoms.
Prop up piece 7 and voussoir 6 coplanes, and be positioned at the two ends of the cross-sectional periphery diameter of guiding coring tube 4.
Under the coring device before the hole in advance with wire rope 2 colligations the guiding coring tube 4 in, the exit of wire rope 2 by tiltedly link connect and be placed on the guiding coring tube 4 on, carry coring device and can carry wire rope 2.The secondary elevator of following Kong Shiyong rig connects wire rope 2, rig master winch lifting drilling rod and coring device.After round trip creeps into and finishes, be lowered to coring device, behind core 8 tops, lift from about 1m, plump, utilize the deadweight and the voussoir 6 in the guiding coring tube 4 of drilling rod and guiding coring tube 4 core 8 wedges are disconnected with the effect of propping up piece 7, core 8 wedges are had no progeny and with secondary elevator receipts wire rope 2 core 8 are entangled firm, and master winch is carried coring device with core 8 propositions then.Rope sling hole 3 distribution that is centrosymmetric, can guarantee leaching process steadily.
Adopt the technology of heavy-caliber base rock boring coring device to be: to be lowered to coring device, behind the disconnected core of wedge, to utilize the wire rope 2 in the coring device directly core 8 to be proposed.Coring process is simple, and operation is reliable, and labour intensity is low, and wide adaptability adapts to the basement rock deep hole especially and gets core.
The tradition heavy caliber is got core and is needed frequent servant colligation core at the bottom of the hole; be subjected to that hole wall is stable, in the aperture protection, Mechanical Reliability, hole in underground water, the hole pumping equipment Electrical Safety, personnel operation skill level etc. influence; the probability that personal injury occurs is very big, and it is bigger particularly to get core danger for deep hole.Do not need the operating personnel to go into the well after adopting heavy-caliber base rock boring coring device, thoroughly stopped potential safety hazard, improved construction safety.
The traditional handicraft procedure that only draws water will take and get more than 60% of core time, adopt behind the heavy-caliber base rock boring coring device because technology is simple, and the servant need not draw water, shortened the engineering time greatly, the efficient height, it is complete, smooth to get core, and taking rate is up to more than 95%.
The heavy-caliber base rock boring coring device handling ease, simple in structure, cost is low.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
