Description
Technical field
The present invention relates to spherical ess-strain monitoring device that is a kind of multi-direction and can combining, and in particular to mined out to mine
Area's filling quality or underground engineering carry out the device of ess-strain monitoring analysis, belong to Geological Hazards Monitoring, goaf filling matter
Amount monitoring field.
Background technology
Early stage, China was restricted by mining technique level, and many mining methods use barnyard structure or pillars of a house structure, this
Mining mode causes the goaf of many danger to leave.Goaf forms certain danger to the building or road on top and periphery
It is dangerous, and some goafs also constitute certain threat to mining face under mine, and potential safety hazard is brought to production from now on.In recent years
There is multiple surface collapse, erecting dense individual props event in China, country strengthens to goaf harnessing, and one of which method is exactly right
Goaf is filled, and the disaster that gob collapse causes is administered with this.But how is the quality of goaf filling, after filling
Whether potential safety hazard is still present, related art method is not detected and verified now.
Under the geological conditions such as complicated joint fissure, stress, underground water, rock mass form and mechanics parameter, underground engineering
The structure for changing initial rock stress field and natural ground/rock mass is excavated, the safety of engineering depends greatly on country rock in itself
Mechanical characteristic and self-stable ability.Existing monitoring means is unable to reach multi-direction stress-strain monitoring, it is more difficult to real-time monitoring
Be incorporated in information-based monitoring system.
The multi-direction and combined spherical ess-strain monitoring device that the present invention is provided, by literature search, has no and this
Invention identical open source literature is reported.
The content of the invention
It is an object of the invention to overcome the deficiency of prior art, and provide a kind of multi-direction and combined spherical stress
Strain monitoring device, specifically carries out the device of ess-strain monitoring analysis to mine worked-out section filling quality or underground engineering.
The present invention is monitored for goaf filling quality and the multi-direction stress-strain of underground engineering, is tied according to monitoring
Fruit finally deduces the change situation of goaf filling quality and underground engineering ess-strain with reference to goaf three-dimensional configuration.
Spherical ess-strain monitoring device that is of the invention multi-direction and can combining includes：It is upper and lower with spheroid (4) respectively
The connection flexible pipe (1) of end connection, the connection (2) being placed in connection flexible pipe (1), the strain being placed on spheroid (4) inner surface
Piece (3), spheroid (4) is connected the nine axle attitudes that flexible pipe (1) is connected, the other end and mainboard (6) are connected with upper end by line one end
Instrument chip (5), is placed in sphere shell (4) and is connected with lower end the mainboard (6) that flexible pipe (1) is connected.
The present invention is prepared according to a conventional method using part purchased in market or material.
The beneficial effects of the present invention are：
The apparatus structure is simple and convenient to operate.Split with the presence or absence of big in goaf that can not only be after accurate measurements filling
The situation of change of seam or Quality of filling body, it is also possible to the stress and strain feelings for monitoring charges and underground engineering around underground
Condition.
Brief description of the drawings
Fig. 1 is apparatus of the present invention structural representation
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Spherical ess-strain monitoring device that is of the invention multi-direction and can combining includes：Respectively with the upper and lower side of spheroid 4
The connection flexible pipe 1 of portion's connection, the connection 2 being placed in connection flexible pipe 1, the foil gauge 3 being placed on the inner surface of spheroid 4, spheroid 4,
The nine axle attitude instrument chips 5 that flexible pipe 1 is connected, the other end and mainboard 6 are connected are connected with upper end by line one end, are placed in outside spheroid
It is connected in shell 4 and with lower end the mainboard 6 of the connection of flexible pipe 1.
The present invention is prepared according to a conventional method using part purchased in market or material.
Ess-strain monitoring device of the invention is spheroid 4, and 24 foil gauges 3 are uniformly pasted on its inwall, it is ensured that monitoring
Monitored to the pressure from all directions and miniature deformation.4 built-in nine axle attitude instrument chips 5 of spheroid, are used to obtain ball peace
Initial attitude after dress, the shell of spheroid 4 avoids the interference and shielding to earth magnetism magnetic field using ABS materials, while guarantee is arranged on
Damage of facilities is prevented from during underground.Spheroid 4 is built-in with data acquisition mainboard 6,6 pairs of nine axle attitude instrument 5 of the mainboard and each strain
The data of piece 3 are acquired, and connection 2 is sent data in Upper system.
Nine axle attitude instrument chip 5 uses 485 mechanicss of communication, is calculated by ground magnetic component and obtains the current orientation of device, leads to
Cross and calculate the current inclination angle of gravitational acceleration component acquisition device, deviation when being laid with device using the current rotation of device is obtained
Obtain corner, the current attitude of determining device.
24 foil gauges 3 are uniformly pasted on the inwall of spheroid 4, deformation is produced after spheroid 4 is squeezed, cause foil gauge 3
The change of upper resistance chip, so as to obtain its strain value.The attitude of different times is determined by nine axle attitude instrument 5, stress is learnt
Direction and strain size, the direction of extrusion of the whole charges of affirmative and the quality condition of charges.
Ess-strain monitoring device of the invention is needed to be installed on the spot, and addressing is carried out first, hole depth is determined, while really
Fixed required device quantity, is assembled according to device quantity.
Device just will at the scene carry out magnetic field correction, i.e. hand-held device in assembling, several circles are rotated in the air and completes magnetic field school
Just.
Linked using stainless steel flexible hose 1 between each device, the concatenation in stainless steel flexible hose 1 of connection 2.Between device
Determine away from according to actual conditions.
The goaf having been filled with is placed a device into wherein using hole knockout, and device refills filling out for same media after placing
Thing is filled, allows it fully to be merged with surrounding filler.The goaf of new filling, after its filling in 2 days and filler does not coagulate completely
Gu when, punched, device is vertically transferred in hole, initial attitude is determined roughly, for later data analysis.
After device transfers to specified location, hole is filled, reserved communication cable 2.
The number that connection 2 is connected on collection mainboard 6 is adopted on the interface of module, and number adopts module to be carried out with signal conversion module
Connection, then can send data to Data Analysis Services module device according to field condition using holding wire, optical fiber, netting twine
Interior, Data Analysis Services module realizes building for this system with display module equipment in public network, finally.
