Abstract
A scanning detector of surrounding rock cracks can directly observe crack developing state and surrounding rock failure state on wall of drilled hole along hole depth through drilling hole on surrounding rock. Utilizing micro-digital shooting head connected to computer, surrounding rock loose range can be described quantitatively. Sonar transmitter can be used to record the reflection wave state along the hole depth and quantitatively describe the loose range of surrounding rock. So that the different support structure required by various underground engineering can be provided.
Description
1. technical field
Underground works comprises all metals and non-metal mine underground excavation.
2. background technology
All underground workss are all destroyed initial stress equilibrium state in when excavation as tunnel, tunnel, cavern and yard, stress make country rock be in different destruction and stress from new distribution, therefore to carry out corresponding supporting during at excavation in underground works.The most general support pattern is bolt supporting at present, and the most basic support principle of this supporting is control, supporting rock crusher band, gives full play to and utilizes the deep to stablize the country rock supporting role.Rationally the basic foundation of support pattern is excavation back tunnel surrounding rock failure scope and degree.This patent not only can realize taking horizontal picture can also take vertical hole wall picture continuously along hole depth simultaneously, qualitative observation wall-rock crack directly perceived more and destructiveness and loose range.In addition, can realize quantitative description surrounding rock failure and loose range by sonar or ultrasonic investigation.The realization of this patent selects the underground engineering support mode to have wide practical value to safe and reasonable.
3. summary of the invention
1) on the boring probe, miniature digital camera is installed, is taken along hole wall continuously, as shown in the figure.
2) on the boring probe, miniature sonar emitting head is installed, is tested along hole wall continuously, judge the hole wall crack length and the degree of depth, quantitatively divide the damage envelope of country rock, as shown in the figure according to the reflection wave shape.
3) digital camera all is connected (USB) with the sonar emitting head with computing machine, and observed result calls and prints after can observing and can store and being equipped with.
4) realized qualitative and quantitative description to the damage envelope of underground engineering surrounding rock, for supporting design provides reliable basis.
5) realize from destroying the qualitative and quantitative division of being with to aperture country rock scope at the bottom of the hole.
4. description of drawings
Fig. 1 is a wall-rock crack scanning detector principle of work synoptic diagram, and a whole set of scanning and detecting instrument is made up of probe, lead and receiver.Fig. 2 is the sonde configuration synoptic diagram, in the probe both sides miniature digital camera head and sonar transmitter is housed respectively, and probe directly is connected with computing machine by lead.Fig. 3 is the boring longitudinal profile synoptic diagram that camera is taken along hole wall, Direct observation hole wall crack state.Fig. 4 is the reflection bellows-shaped synoptic diagram of sonar transmitter along the wall of a borehole record, with this quantitative description hole wall crack state.
5. embodiment
1) in underground works different location and different azimuth to the country rock hole of drilling, the degree of depth can be determined according to country rock intensity and state.As rock mass country rock hole depth is about 10 meters, and will reach 15 meters or 20 meters to coal body country rock hole depth.
2) beat the finishing drilling hole after, water will be rinsed well in the hole, treats the hole wall drying.
3) will pop one's head in along boring send at the bottom of the hole.After treating to connect, progressively will pop one's head in and move, take hole wall photo and record sonar reflection wave continuously to the aperture with receptacle.
4) according to the standard reflection ripple of having demarcated, carry out data processing, form figure by computing machine.
5) accurately divide wall rock loosening scope and broken according to picture and reflection ripple, for supporting rationally provides reliable theoretical foundation for scope.
Claims (4)
1. accurately determine surrounding rock failure, loosening and range of stability by country rock boring.
By miniature digital camera and computing machine Direct observation hole wall crack distribute, wall rock loosening scope and obtain different azimuth from the longitudinal sectional drawing of holing to the aperture at the bottom of the hole.
3. utilize sonar or ultrasonic transmitter according to the surrounding rock failure of reflection ripple form quantitative description, loosening and range of stability and draw the vertical country rock constitutional diagram of corresponding country rock.
4. inlaying camera on a probe simultaneously links to each other with computing machine with sonar sounding set and while.
