Description

A kind of remote grouting method and grouting system
Technical field
The present invention relates to coal mine down-hole drilling slurry injection technique field, specifically a kind of remote grouting method and slip castings System.
Background technique
The hydraulic grouting pump that underground coal mine generallys use at present carries out slip casting, this grouting process, hydraulic slip casting to drilling Pump utilizes the hydraulic system of drilling machine, carries out slip casting to drilling (generally within 10m) near purpose drilling.So slip casting away from From limited, equipment must follow drilling, and in particular location, relocation equipment is difficult, and slip casting is caused to be obstructed.
Summary of the invention
The technical problem to be solved by the present invention is to how grouting method be made to be suitable for subsurface environment.
The present invention solves above-mentioned technical problem by the following technical programs:
A kind of remote grouting method, comprising the following steps:
1) hydraulic system of grouting pump and drilling machine is connected firmly;
2) work is checked before slip casting
Check whether pipeline has blocking using clear water pump testing, and with pressure wind, it is ensured that pipeline is unobstructed;Detect drilling machine pressure gauge and Whether release triple valve is unobstructed;Check whether signal system is sensitive;
3) slip casting
31) cement slurry preparing barrel slurrying is used, while grouting pipeline being connect with aperture Grouting Pipe;Grouting Pipe uses more high-pressure glues Pipe head and the tail connection is formed;
32) by slip casting signal transmitted by signal system, operator starts drilling machine and grouting pump starts slip casting;
33) after one barrel of slurry has been infused, slurry is sent by signal system and is finished signal, operator closes grouting pump and aperture Ball valve stops slip casting;
Repeat 31) -33), until Present Borehole slip casting is completed;
4) after Present Borehole returns slurry, operator unloads later according to signal-off grouting pump and aperture ball valve and release Aperture Grouting Pipe moves to next drilling, notifies operator to open grouting pump by signal after the installation is completed, and so on, directly It is finished to all bored groutings.
Preferably, the signal system includes signaling point, concrete signal control method at signaling point and slip casting at cement slurry preparing barrel Are as follows: after the completion of slurrying, the operator of signaling point to transmission slip casting signal at slip casting while opening grouting pump at slurrying, at slip casting Operator starts drilling machine and starts slip casting, and after the slurry in cement slurry preparing barrel is finished, signaling point operator is at slip casting at slurrying It sends and stops slip casting signal and simultaneously close grouting pump, slip casting point operator aperture ball valve waits next slip casting signal again again It opens;When Present Borehole returns slurry, slip casting signaling point sends slip casting to slurrying point and completes signal, and slurrying point operator closes note Stock pump waits next signal to restart again.
The present invention also provides a kind of remote grouting systems, applied to above-mentioned method;Including borer system, hydraulic slip casting Pump, pulping system, Grouting Pipe;The hydraulic grouting pump is connected by the hydraulic system of pipeline and borer system, and Grouting Pipe passes through Hydraulic grouting pump is connect with pulping system.
The present invention has the advantages that
Grouting Pipe is made by more end to end high-pressure rubber pipes, is suitable for the bored grouting demand without distance, and Large-scale grouting equipment is not needed to carry, particularly with the position of transportation system's complexity, advantage is more obvious.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of 1 grouting system of the embodiment of the present invention.
Specific embodiment
The effect of to make to structure feature of the invention and being reached, has a better understanding and awareness, to preferable Examples and drawings cooperation detailed description, is described as follows:
Embodiment 1
As shown in Figure 1, a kind of remote grouting system, including ZDY-3200S type hydraulic drill rig one, ZBY3/7.0-11 Type hydraulic grouting pump one, cement mixer barrel one, the several head and the tail of Φ 25mm × 10m high-pressure rubber pipe connect to form 1 (root of Grouting Pipe According to needing to increase and decrease);Hydraulic grouting pump is connected by the hydraulic system of pipeline and borer system, and Grouting Pipe 1 passes through hydraulic grouting pump It is connect with pulping system.
Embodiment 2
A kind of remote grouting method, comprising the following steps:
Step 1 checks whether grouting pump is connect with drilling machine oil pipe secured, and carries out whether just second protection checks grouting pump Often operating, checks whether pipeline is connected firmly and carries out second protection.
Step 2, with clear water pump testing, it is ensured that grouting pump running is normal;Check whether pipeline has blocking with pressure wind, it is ensured that pipeline It is unobstructed.
Step 3 checks that whether intact drilling machine pressure gauge, grouting pump pressure gauge be accurate, checks whether release threeway has blocking.
Step 4, operator are in place: a drill hole at least people also serves as " signalman " as slip casting responsible person, at slurrying extremely Few two people a, wherein people also serves as " signalman ";Whether checkpoint bell signal is sensitive reliable.
Step 5, slurrying people's slurrying, while 1 tunnel of Grouting Pipe is connect by slip casting responsible person with aperture Grouting Pipe 1, end of operation Grouting behind shaft or drift lining responsible person gets (two o'clock) notice slurrying people ready, and slurrying people gets response ready, while starting drilling machine and starting slip casting.
After step 6, one barrel of slurry have been infused, " signalman " gets (a long point) notice slip casting responsible person ready at slurrying, and other side gets ready It responds, and closes aperture ball valve, slurrying people continues slurrying, and slurrying terminates to get (two o'clock) notice slip casting responsible person ready, and slip casting is responsible for People opens aperture ball valve, and gets (two o'clock) response ready, slurrying responsible person's turn on pump, and so on.
After slurry is returned in step 7, first hole, slip casting responsible person gets (a long point) notice slurrying people ready, beats after slurrying people's termination of pumping Point is responded.Slip casting responsible person closes aperture ball valve and release and (is installing release between the second root canal road apart from first, aperture Threeway) after unload aperture Grouting Pipe 1 and move to next hole.Get notice slurrying people ready after the installation is completed, and so on, until last One bored grouting terminates.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and Improvement is both fallen in the range of claimed invention.The present invention claims protection scope by appended claims and its Equivalent defines.
