Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated:
As shown in Figure 1, Figure 2, Figure 3 shows, rock cranny detection sensor is formed primarily of supporting tube 1, pkr 2, medium sensor 3, tail end shutoff 6, wire 9, on supporting tube 1, interval is furnished with pkr 2, and the tube wall of the supporting tube 1 between every two pkrs 2 is provided with medium sensor 3; Tail end at supporting tube 1 is provided with tail end shutoff 6; Wire 9 one end connecting media sensor 3, is drawn by wire joint 8 through supporting tube 1 inside, and the other end is connected to Signal reception device. The utility model can to whether there is UNICOM crack in the rock mass not yet disclosed, or structural plane, the spatial distribution in crack and connection property carry out detecting and obtain quantitative result, can be rock mass engineering project design and construction and provides basic data, it is to increase the reliability of engineering.
It is between above-mentioned each parts and it is tightly connected, supporting tube 1 with the tube wall of pkr 2 correspondence position have ventilating pit 10, make supporting tube 1 and pkr 2 inside form the enclosed space of mutual UNICOM. Every two adjacent packers 2 and between medium sensor 3 form a probe unit; Pkr 3 after inflation makes probe unit separate and is independent of each other; The interval of pkr 2 is more little, and probe unit quantity is more many, and the detection accuracy in crack is more high.
Wherein, supporting tube 1 is for having the pipe body of certain wall thickness and rigidity, and its cross-sectional shape is generally circle, and on it, interval has ventilating pit 10;
Pkr 2 is made up of packing capsule 4 and packing cuff 5, and packing capsule about 4 respectively arranges 1 each packing cuff 5; Packing capsule 4 can be fixed on supporting tube 1 by packing cuff 5, and ensures stopping property;
Medium sensor 3 points can be interposed between in separate probe unit after being inflation by the effect of pkr 2, prevents the induction medium poured in from rock cranny 13 from gushing along the space between detection boring 12 and supporting tube 1 to adjacent detector unit. Ensure the medium sensor 3 in each probe unit with this, and can only sense and conduct, from the crack with self place probe unit UNICOM, the induction medium come, thus realize the location in UNICOM crack. And the interval of pkr 2 is more little, probe unit quantity is more many, and the detection accuracy in crack is more high.
Packing capsule 4 is flexible thin-walled cystidium, is generally rubber bag tank, and when air pressure in pkr 2 raises, packing capsule 4 bulges, and contacts with the wall of detection boring 12 and closely connected, reaches the object of packing; When air pressure in pkr 2 reduces, packing capsule 4 is to contract.
Medium sensor 3 is fixed on the outer wall of supporting tube 1, and is connected with Signal reception device by wire 9, when medium sensor 3 senses the probing medium transmitted from crack, immediately by wire 9, signal is sent to Signal reception device.
Medium sensor 3 can adopt water sensor; When detecting in moisture rock mass, the medium sensor of other type can be adopted.
Tail end shutoff 6 is provided with inflation joint 7 and wire joint 8; Wire joint 8 is for drawing supporting tube 1 by wire 9; Inflation joint 7 is for supporting tube 1 inner inflatable, or outwards exits.
Above-mentioned each parts can adjust the yardstick of sensor as required, it is achieved different application: as big scale sensor can carry out stratal configuration detection; Mesoscale sensor can carry out structure of rock mass face, crack detects in advance; Small scale can carry out wall-rock crack detection; Microscale can carry out crack rock shop experiment or model trial detection.
As shown in Figure 4, the concrete use step of the utility model sensor is as follows:
Step 1 pore-creating in crack rock 11, bores out detection boring 12 and medium filling orifice 14 respectively, and clears up the impurity in detection boring; The diameter of described detection boring 12 should slightly larger than sensor external diameter, and the degree of depth is slightly larger than sensor length; Described medium filling orifice with detection boring distance according to detection it needs to be determined that, its degree of depth generally be greater than detection boring the degree of depth;
The utility model sensor is put into detection boring 12 after detecting the satisfied requirement of stopping property of pkr 2 by step 2;
Wire 9 is connected to Signal reception device by step 3;
Step 4 and is kept being filled with high pressure gas in support bar 1 by inflation interface 7, and the air pressure in support bar 1 generally should be greater than medium injection pressure;
Step 5 continues to inject induction medium until detection terminates in medium filling orifice 14, and induction medium should mate with induction pick-up 3 phase;
Step 6 real time record medium inductor block 3 in induction medium injection process reaches the information of Signal reception device, thus is analyzed by the parameters of fissure in rock mass.
Step 7 detection terminates, and discharges high pressure gas by inflation interface 7, extracts sensor.
The above; it is only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
