Abstract
The utility model provides a kind of Starch Level control device for stratum, multilayer goaf grouting and reinforcing, this control device is in series with power supply successively, alarm and stationary installation, stationary installation is fixed in Grouting Pipe, stationary installation comprises positive pole fixator and negative pole fixator, alarm is by the flashing light alarm of connecting successively, buzzer siren and signal amplifier composition, alarm one end is connected with the positive pole of power supply, the other end is connected with positive pole fixator by positive electrical wire, the negative pole of power supply connects negative pole fixator by negative electrical wire, positive pole fixator is that metal material is made, negative pole fixator is that insulating material is made.During slip casting, lower floor's goaf is full, Starch Level will along upwards lifting of holing, when Starch Level rise to bury negative pole fixator time, due to the electric action of slurries, circuit ON, buzzer siren just can sound the alarm, and flashing light alarm also can send light flash simultaneously, remind staff's Starch Level to rise to predetermined altitude, stop slip casting.
Description
Technical field
The utility model relates to a kind of Starch Level control device for stratum, multilayer goaf grouting and reinforcing, particularly relates to the Starch Level control warning device that one is applicable to multilayer goaf " upstriker segmenting slip casting " technique.
Background technology
Along with the development of mining area construction, developing discarded soil, old goaf becomes the important channel solving mining area construction land used and put upon the full stretch.Old goaf and overlying strata thereof are after long natural compacting, the problems such as the underground cavity that exploitation causes, absciss layer, crack and Collapsed zone still exist, and very easily produce when being subject to outer force-disturbance " activation ", threaten the safety of buildings or structures, grouting and reinforcing becomes the main path addressed this problem.In the governance process of old dead zone, usually face the phenomenon of mutil-coal seam mining, for this problem, mainly contain " downstriker segmenting slip casting " and " upstriker segmenting slip casting " two kinds of construction technologies.In order to control grouting cost, shorten the construction period, improve construction quality, upstriker segmenting slip casting becomes the first-selected construction technology of stratum, multilayer goaf grouting and reinforcing.But in construction process, the phenomenon of slurry is altered in the upper and lower goaf of normal generation, namely time to lower one deck dead zone slip casting, the lifting height of Starch Level cannot be monitored, just slip casting can be stopped after only having adjacent slip casting aperture running pulp, now just late, when causing later stage grouting under pressure under stop-grouting plug less than setting layer position, goaf layering grouting under pressure cannot be realized.
Utility model content
The purpose of this utility model is to provide a kind of Starch Level control device for stratum, multilayer goaf grouting and reinforcing, and this control device achieves the control to Starch Level height in slip casting process, avoids upper and lower goaf to alter the generation of slurry phenomenon.
The utility model adopts following technical scheme:
A kind of Starch Level control device for stratum, multilayer goaf grouting and reinforcing, described control device is in series with power supply successively, alarm and stationary installation, described stationary installation comprises positive pole fixator and negative pole fixator, described alarm is by the flashing light alarm of connecting successively, buzzer siren and signal amplifier composition, alarm one end is connected with the positive pole of power supply, the other end is connected with positive pole fixator by positive electrical wire, the negative pole of described power supply connects negative pole fixator by negative electrical wire, described positive pole fixator is made up of metal material, described negative pole fixator is made up of insulating material.
Preferably, described positive pole fixator and negative pole fixator are all fixed in Grouting Pipe, and positive pole fixator is positioned at the middle part of Grouting Pipe, and negative pole fixator is positioned at the front end of Grouting Pipe.
The beneficial effects of the utility model are:
The warning device that the utility model adopts, in goaf grouting process, when lower floor's goaf is full, Starch Level will along upwards lifting of holing, when Starch Level rises to the negative electrical wire buried on negative pole fixator, due to the electric action of slurries, power supply is communicated with formation current return with alarm, buzzer siren just can send buzzing alarming sound, meanwhile flashing light alarm also can send light flash, thus play warning function, staff's Starch Level is so just reminded to rise to predetermined altitude, slip casting can be stopped, reach the object of monitoring Starch Level, avoid the phenomenon generation that slurry is altered in upper and lower goaf.
Accompanying drawing explanation
Fig. 1 is the goaf grouting filling integral structural representation comprising the utility model.
Wherein, 1 power supply, 2 flashing light alarms, 3 buzzer sirens, 4 signal amplifiers, 5-1 positive electrical wire.5-2 negative electrical wire, 6-1 positive pole fixator, 6-2 negative pole fixator, 7 Grouting Pipe joints, 8 Grouting Pipe, 9 topsoil, 10 more complete horizon ds, 11 fissure zones, 12 caving zones, 13 coal seams, 14 seat earths.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Composition graphs 1, a kind of Starch Level control device for stratum, multilayer goaf grouting and reinforcing, this control device is in series with power supply 1, alarm and stationary installation successively, stationary installation comprises positive pole fixator 6-1 and negative pole fixator 6-2, alarm is made up of the flashing light alarm 2 of connecting successively, buzzer siren 3 and signal amplifier 4, signal amplifier 4 can strengthen the intensity of electric signal, ensures in the normal work lower than alarm when human safety voltage.Alarm one end is connected with the positive pole of power supply 1, the other end is connected with positive pole fixator 6-1 by positive electrical wire 5-1, the negative pole of power supply 1 is connected on negative pole fixator 6-2 by negative electrical wire 5-2, positive pole fixator 6-1 is made up of metal material, and negative pole fixator 6-2 is made up of insulating material.Positive pole fixator and negative pole fixator are all fixed in Grouting Pipe 8, and Grouting Pipe 8 is iron pipe, Grouting Pipe 8 has Grouting Pipe joint 7, and positive pole fixator 6-1 is positioned at the middle part of Grouting Pipe 8, and negative pole fixator 6-2 is positioned at the front end of Grouting Pipe 8.
Illustrate for two-layer goaf, in goaf grouting process, Grouting Pipe is extend into lower floor goaf by grouting hole and carries out slip casting, when lower floor's goaf is full, Starch Level will along upwards lifting of holing, when Starch Level rise to bury negative pole fixator 6-2 time, due to the electric action of slurries, power supply 1 is communicated with formation current return with alarm, flashing light alarm 2 just can send light flash, meanwhile buzzer siren 3 also can send buzzing alarming sound, thus play warning function, staff's Starch Level is reminded to rise to predetermined altitude, slip casting can be stopped, reach the object controlling Starch Level height in slip casting process, avoid the phenomenon generation that slurry is altered in upper and lower goaf.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
