Abstract
The utility model relates to a testing device for a long drill hole by virtue of a deep-part base point method. The testing device comprises a metal back-and-forth piercing device, a fixing device, a metal steel pipe, a connecting device, threads, a steel wire rope, a drilling machine and a drill stem, wherein the metal back-and-forth piercing device is arranged on the fixing device and is connected with one end of the steel wire rope, the other end of the steel wire rope stretches out of the drill hole, the fixing device is sheathed and connected with the metal steel pipe of the connecting device, and the connecting device is connected with the drilling stem on the drilling machine by the threads. The testing device can avoid the phenomenon that the fixing device is prevented from being transported to designed depth when the wall of the drill hole is broken, is simple to operate and can ensure the accuracy of testing results and improve the working efficiency.
Description
Technical field
the utility model relates to the proving installation in a kind of coal mine excavation operation, especially a kind of long drilled holes deep basic point method proving installation.
Background technology
coal mine excavation activity can cause the displacement of coal and rock generation on every side, needs the test digging space displacement of deep coal and rock on every side, for digging supporting, impulsion pressure control, protective seam effect expedition etc. provide underlying parameter.Traditional mensuration dilatational strain amount adopts deep basic point method more; Be through the construction layer-through drilling; Respectively install and fix a basic point at seam roof and base plate; Device respectively connects a reinforcing bar, and extracts through boring, obtains deflection after relative displacement through measuring two reinforcing bars and bore angle convert.In traditional method, fixed base point is fixing through a pair of gad implement device.But there is shortcoming in this method: gad is stopped up by the barrier in the boring when boring is transported easily, and can't be transported to assigned address; The coal rock layer release causes boring aperture to change, and it is loosening to make that the gad that fixed originally takes place, even produces slip, makes test result be affected; Gad can't transport with machine tool, can't realize transporting of long distance.
The utility model content
The deficiency of the classic method of coal and rock displacement when coal mine excavation is tested in order to overcome in
; The utility model provides a kind of long drilled holes deep basic point method proving installation, and this device is connected stationary installation through active coupling arrangement with borer drill rod, utilize rig that stationary installation is sent into assigned address; Not only can avoid hindering stationary installation and be transported to projected depth because of borehole wall is broken; And simple to operate, test result is accurate, has improved work efficiency.
the utility model solves the technical scheme that its technical matters adopted: this long drilled holes deep basic point method proving installation comprises that metal returns thorn, stationary installation, metal steel pipe, coupling arrangement, screw thread, wire rope, rig, drilling rod; The stationary installation of this long drilled holes deep basic point method proving installation is provided with metal and returns thorn; Metal returns thorn and links to each other with an end of wire rope; The other end of wire rope extends boring outside, and the metallic steel pipe box load of stationary installation and coupling arrangement connects, and coupling arrangement passes through screw thread and links to each other with drilling rod on the rig.During use, earlier down to layer-through drilling, drilling construction to rock to be measured; After through rig stationary installation being sent into assigned address; Withdraw from drilling rod and make coupling arrangement separate, and withdraw from boring, the pulling wire rope with drilling rod with stationary installation; Metal returns thorn under the pulling function of wire rope, thrusts the wall of a borehole; After autonomous the fixing of finishing device, guarantee that wire rope can move freely in boring, and fix wire rope, marked, observational record every day length of steel wire rope changes, in conjunction with bore angle, the displacement of computing formation.
The beneficial effect of
the utility model is; This long drilled holes deep basic point method proving installation not only can be avoided hindering stationary installation because of borehole wall is broken and be transported to projected depth; And simple to operate, test result is accurate, has improved work efficiency.
Description of drawings
are described further the utility model below in conjunction with accompanying drawing and embodiment.

Among
figure, 1. boring, 2. metal returns thorn, 3. stationary installation, 4. metal steel pipe, 5. rock, 6. coupling arrangement, 7. screw thread, 8. wire rope, 9. rig, 10. drilling rod.
Embodiment
in Fig. 1, this long drilled holes deep basic point method proving installation comprises that metal returns thorn 2, stationary installation 3, metal steel pipe 4, coupling arrangement 6, screw thread 7, wire rope 8, rig 9, drilling rod 10; The stationary installation 3 of this long drilled holes deep basic point method proving installation is provided with metal and returns thorn 2; Metal returns thorn 2 and links to each other with an end of wire rope 8; The other end of wire rope 8 extends boring 1 outside; Stationary installation 3 is connected with metal steel pipe 4 suits of coupling arrangement 6, and coupling arrangement 6 links to each other with drilling rod 10 on the rig 9 through screw thread 7.During use, earlier down to layer-through drilling 1, drilling construction to rock 5 to be measured; After through rig 9 stationary installation 3 being sent into assigned address; Withdraw from drilling rod 10 and make coupling arrangement 6 separate automatically, and withdraw from boring, pulling wire rope 8 with drilling rod 10 with stationary installation 3; Metal returns thorn 2 under the pulling function of wire rope 8, thrusts the wall of a borehole; After autonomous the fixing of finishing device, guarantee that wire rope 8 can move freely in boring, and fix wire rope 8, marked, observational record every day length of steel wire rope changes, in conjunction with bore angle, the displacement of computing formation.
