Abstract
It the utility model is related to a kind of karst cavity area slip casting state real-time monitoring system.Karst foundation, which collapses, threatens railway operation safety, injects cement grout to karst foundation for this.Due to using any investigation way at present, method there is no to investigate thoroughly situations such as being connected with each other passage between the solution cavity, fluid bowl, solution cavity of solvable rock stratum.The utility model sets injected hole from ground to karst cave, and Grouting Pipe is set in injected hole；Camera in Grouting Pipe bottom mounting apertures, ground monitor is set at ground, and deep dynamic consolidation head passes through cable and accesses ground surveillance instrument.Using the utility model, filling, the wastage of grouting serous fluid can be monitored in real time, to the passage for causing grouting serous fluid to be lost in, accelerated cement slurry, batch (-type) injection medium coarse sand, the timely leak stopping of cement mortar can be used, to control construction investment, reducing environmental pollution has great importance.
Description
Technical field
The utility model belongs to karst area road building technology field, and in particular to a kind of karst cavity area slip casting state is real-time
Monitoring system.
Background technology
Karst foundation, which collapses, threatens railway operation safety, injects cement grout to karst foundation for this.Due to using at present
Any investigation way, method there is no to investigate thoroughly situations such as being connected with each other passage between the solution cavity, fluid bowl, solution cavity of solvable rock stratum.Karst region
During base injecting treatment, especially in karst area, grouting serous fluid is very serious along the passage loss between solution cavity, both causes work
The waste of journey material, pollutes environment again.
Construction technical staff is in the case of no equipment, instrument, it is difficult to grasp the filling of underground slurries in time, be lost in feelings
Condition.Due to not knowing about the wastage of grouting slurries, effective reply engineering measure can not be used, is blocked along between solution cavity
Passage, solves the losing issue of grouting serous fluid in time.
The content of the invention
The purpose of this utility model is to provide a kind of karst cavity area slip casting state real-time monitoring system, can monitor rock in real time
The filling of molten hole area grouting serous fluid, wastage.
Technical scheme is used by the utility model：
A kind of karst cavity area slip casting state real-time monitoring system, it is characterised in that：
Injected hole is set from ground to karst cave, Grouting Pipe is set in injected hole；
Camera in Grouting Pipe bottom mounting apertures, ground monitor is set at ground, and deep dynamic consolidation head is accessed by cable
Ground surveillance instrument.
Deep dynamic consolidation head is installed on more than slip casting bottom of the tube at 2 ~ 3m.
Injected hole is set to 2m below karst cave bottom plate.
The utility model has advantages below：
Relative to the grouting equipment of routine, the utility model can monitor karst cavity area in real time during foundation grouting
Grouting serous fluid filling, wastage, construction technical staff take counter-measure in time according to the situation of monitoring.
Brief description of the drawings
Fig. 1 the utility model schematic cross-sectional views.
In figure, 1- Grouting Pipes, 2- deep dynamic consolidation heads, 3- ground surveillance instrument.
Embodiment
The utility model is described in detail with reference to embodiment.
A kind of karst cavity area slip casting state real-time monitoring system is the utility model is related to, is set from ground to karst cave
Injected hole, injected hole are set to 2m below karst cave bottom plate.Grouting Pipe 1 is set in injected hole；In the bottom mounting apertures of Grouting Pipe 1
Camera 2, deep dynamic consolidation first 2 are installed on more than the bottom of Grouting Pipe 1 at 2 ~ 3m.Ground monitor 3, deep dynamic consolidation are set at ground
First 2 access ground surveillance instrument 3 by cable.
During construction：
Step 1：Drill to 2m below solution cavity bottom plate.
Step 2：At away from the vertical 2 ~ 3m of Grouting Pipe more than 1, camera 2 in mounting hole.
Step 3：Deep dynamic consolidation first 2 is connected with ground surveillance instrument 3 by cable.
Step 4：After vertical Grouting Pipe 1 inserts foot of hole, vertical Grouting Pipe 1 is connected with grouting pump.
Step 5：Ground surveillance instrument 3 is opened, opens grouting pump.
Step 6：By ground surveillance instrument 3, the grouting serous fluid filling of karst cavity area, wastage are monitored in real time.
Step 7：To prevent slip casting face from flooding deep dynamic consolidation first 2, vertical Grouting Pipe 1 should be protected with the progressively lifting of slip casting face
Deep dynamic consolidation head is held away from slip casting face 2m, until this bored grouting is completed.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
