Abstract
The invention discloses a device and method for preventing a hollow inclusion cable from winding during ground stress measurement, and belongs to and is mainly applied to the field of mine ground stress measurement. The device comprises a hexagonal nut (1), a screw rod (2), a connecting screw thread (3), a rubber sealing sleeve (4) and a cable hole (5). The method comprises the steps as follows: enabling the mounted and cured hollow inclusion cable (2) to penetrate through a coring bit (13), a core barrel (12), a drill rod (11) and a water supply device (10) respectively, then enabling the hollow inclusion cable (2) to penetrate through the water supply device (10) at the rear end of the drill rod (11), and finally enabling the hollow inclusion cable (2) to penetrate through the cable hole (5) of the ground-stress hollow inclusion cable winding prevention device (9); and aligning the connecting screw thread (3) and rotating the ground-stress hollow inclusion cable winding prevention device (9), enabling the cable (7) to pass through a tension bracket (8), and hanging a weight (6) onto the cable (7) for tensioning the cable (7). According to the device and the method, the operation is simple, the cost is low, and the problem of winding of the hollow inclusion cable during the ground stress measurement is solved.
Description
Technical field
The present invention relates to a kind of terrestrial stress hollow inclusion cable winding device and method of preventing, belong to the geostress survey field, mine that is mainly used in.
Background technology
Terrestrial stress is the basic acting force that causes various underground or open-air ground excavation project deformation and failures, is to determine the engineering rock mass mechanical attribute, carries out Stability Analysis of The Surrounding Rock, realizes the prerequisite of Geotechnical Engineering excavation design and the scientification of decision-making.Only has the terrestrial stress condition of having grasped the concrete engineering zone, could rationally determine the mine total arrangement, choose suitable exploitation and excavation method, determine the optimum section, cross dimensions, excavation step, support form, supporting construction parameter, support time of tunnel and stope etc., thereby guaranteeing stability of surrounding rock.In addition, the terrestrial stress state is also significant to the outstanding research of the stability of earthquake prediction, Evaluation of Regional Crust Stability, oilfield, nuke rubbish storage, rock burst, coal and gas etc.
At present, the trepanning stress relief method is the comparatively ripe a kind of earth stress measuring method of development that the most generally adopts both at home and abroad at present.Hollow inclusion stress relief method is measured in the terrestrial stress process, (hollow inclusion) strainometer leader cable is by core barrel and drilling rod, water-feed (water hyacinth) from the drilling rod rear end passes at last, when overlapping the core releasing, cable is easily with core barrel and drilling rod rotation, and inclusion bottom cable stress is concentrated, and it is disconnected to cause cable to twine, can't carry out geostress survey, so cable needs the special messenger to strain; In addition, the water-feed of drilling rod rear end (water hyacinth) can't supply water cooling boring and strainometer because cable passes, and causes the strainometer reading to be difficult to stablize.
Summary of the invention
Existing in order to overcome (hollow inclusion) strainometer leader cable twines disconnected and supplies the problems such as water cooling boring and strainometer, the present invention designs a kind of terrestrial stress hollow inclusion cable winding device and method of preventing, solve cable and twine the problems such as cut-off water cooling boring and strainometer, reduce measurement links.
Terrestrial stress hollow inclusion cable winding device and the method basis of preventing of the present invention may further comprise the steps:
Beneficial effect of the present invention:
(1) for boring supplies water cooling, thereby prevents that boring and strainometer temperature from raising, and improves measuring accuracy;
(2) method and apparatus structure are simple, operation is rapid, shorten Measuring Time, greatly reduce the test job amount;
(3) prevent that inclusion from damaging, and avoids measuring unsuccessfully.
