Description

Technical Field

[0001] The present invention relates to the technical field of rock grouting, in particular to a rock drilling grouting device and method based on rock permeability. Background Art

[0002] Rock drilling and grouting technology is a key technical means in geotechnical engineering. By injecting slurry into rock boreholes, the slurry can penetrate into the cracks and pores of the rock and solidify, improving the integrity and compressive and shear strength of the rock mass. In water conservancy projects, mining, and other scenarios, cracks in the rock may become channels for groundwater leakage. Grouting can fill the cracks with slurry, forming a water-blocking curtain, blocking the flow of groundwater and preventing disasters such as water inrush and sudden water inrush. However, due to the different permeability of rocks, different drilling and grouting methods are used. Traditional rock drilling and grouting mostly uses a drilling machine to drill the rock, then removes the drill rod, and inserts the grouting rod for grouting reinforcement. During the process of removing the drill rod and installing the grouting rod, some rocks have high permeability and the hole wall collapses or slag leaks, resulting in hole blockage or premature loss of slurry.

[0013] A method for using a rock drilling grouting device based on rock permeability comprises the following steps: Step 1: In the initial state, the mobile bracket is close to the first seat. At this time, the entire drilling and injection mechanism is close to the first seat, and the drill bit is located inside the second seat but does not pass through the second seat; When installing the grouting inner tube, install the inner deep insertion rod thread in the threaded inner groove, then insert the grouting inner tube into the drilling long tube from one end of the drilling long tube, and use the inner deep insertion rod to completely send the grouting inner tube into the drilling long tube, and adjust the angular position of the grouting inner tube so that the connecting head and the long groove correspond, and until the limit plate is movably clamped on one end of the drilling long tube, the grouting inner tube is auxiliary positioned, and then, the valve with the connecting elbow is threadedly installed in the connecting head to realize the installation of the grouting inner tube. At this time, the inner sealing cover seals one end of the drilling long tube to prevent rock chips from entering the drilling long tube during drilling, causing subsequent grouting grooves to be blocked and affecting grouting; Step 2: Use a small drill to drill a positioning groove that matches the fixing bolt at the rock grouting position, and install the second seat in the positioning groove through the fixing bolt thread to fix it, so as to position the drilling device at the rock grouting position; Subsequently, the top and bottom frames are connected by rotating, and the adjusting screw is turned using a tool to adjust the distance between the top and bottom frames until the auxiliary support seat contacts other positions of the rock. Subsequently, an auxiliary support installation groove that matches the auxiliary support bolt is drilled using a small drilling rig, and the auxiliary support bolt is passed through the auxiliary support seat and installed into the auxiliary support installation groove to achieve fixation between the auxiliary support device and the rock. In this way, a triangular stable structure is formed by connecting the top and bottom frames with the entire drilling and injection device, further improving the stability of the drilling and injection device. Step 3: Turn on the second motor to control the driving horizontal shaft to rotate, thereby driving the transmission gear to drive the transmission gear ring and the driving cylinder to rotate at high speed, thereby driving the drilling long tube, the drill bit and the grouting inner tube to rotate at high speed, and cooperating with the first motor to drive the translation screw to rotate, driving the movable bracket to slide translationally on the outside of the guide cross bar toward the side position of the second seat, controlling the drilling long tube, the drill bit and the grouting inner tube to translate into the rock together, and automatically performing deep drilling processing on the rock until the grouting hole processing is completed; Step 4: Install the connecting hose on the connecting elbow and connect the connecting hose to the output port of the grouting pump mechanism. The pressure and flow rate of the grouting pump mechanism will automatically adjust according to the different permeability of the rock. Remove the inner deep insertion rod from the threaded inner groove, and pass the extension rod and positioning block through the long groove and movably clamp them in the drilling long tube, and make the positioning block contact with the outer end of the grouting inner tube; Subsequently, the first motor is turned on to drive the translation screw to rotate in the opposite direction, thereby driving the movable bracket to slide in the opposite direction on the outside of the guide cross bar toward the side of the first seat, thereby controlling the drilling long tube to slowly move in the opposite direction and separate from the grouting hole. At the same time, the hand-held rod is manually held, and the head of the grouting inner tube gradually extends out of the drilling long tube and the drill bit, preventing the grouting inner tube from separating from the grouting hole along with the drilling long tube. At the same time, the grouting pump mechanism and valve are turned on to deliver slurry of appropriate pressure and flow into the grouting inner tube, and the slurry is gradually discharged from the inner position of the grouting hole through the grouting groove at the head. While grouting, the drilling long tube slowly separates from the grouting hole. The drilling long tube will always support the grouting hole during the grouting operation to prevent some high-permeability rocks from causing hole wall collapse or slag leakage, resulting in hole blockage or premature loss of slurry; The grouting operation is completed until the end of the long groove close to the drill bit moves in the opposite direction to the valve. Then, stop grouting, manually disassemble the valve, and install the plug thread in the connector to prevent the slurry from leaking through the connector before solidification. Subsequently, the positioning block continues to press against the outer end of the grouting inner tube, and the drilling tube and the drill bit are continuously controlled to move outward until the drilling tube and the drill bit are completely moved out of the grouting hole. At this time, the grouting inner tube remains in the grouting hole, and the grouting inner tube is completely separated from the drilling tube. Step 5: Remove the fixing bolts and remove all parts of the drilling and injection device except the grouting inner cylinder, inner sealing cover, and limit ring from the rock grouting position; At this time, the limiting ring is exposed outside the rock. Then, the supporting plate is installed on the end of the grouting inner tube close to the limiting ring, and the supporting nut is screwed in. Then, the fixing bolts are installed in the corresponding fixing grooves at the original positioning grooves. The fixing bolts fix the supporting plate, thereby conveniently fixing the grouting inner tube. This enables integrated rock drilling and grouting operations.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a drilling and grouting device, the rock grouting position is automatically deep drilled and the grouting hole is immediately grouting. At the same time of grouting, the drilling long tube slowly separates from the grouting hole. The drilling long tube will always support the grouting hole during the grouting operation to prevent some high-permeability rocks from having hole wall collapse or slag leakage, resulting in hole blockage or premature loss of slurry, thereby improving the effect and efficiency of the entire equipment for rock grouting.

[0015] 2. An inner cover is provided to seal one end of the drilling tube to prevent rock chips from entering the drilling tube during drilling and causing blockage in subsequent grouting.

[0016] 3. By setting up auxiliary support devices, the connecting top frame, the connecting bottom frame and the entire drilling and grouting device form a triangular stable structure, further improving the stability of the drilling and grouting device, thereby further improving the stability of subsequent rock drilling and grouting.

Step 2: Use a small drill to drill a positioning groove that matches the fixing bolt 151 at the rock grouting position, and thread the second seat 121 into the positioning groove through the fixing bolt 151 to fix it, thereby positioning the drilling device 1 at the rock grouting position; Subsequently, the top connecting frame 22 and the bottom connecting frame 23 are rotated, and the adjusting screw 24 is rotated with a tool to adjust the distance between the top connecting frame 22 and the bottom connecting frame 23 until the auxiliary support seat 25 contacts other positions of the rock. Subsequently, an auxiliary support mounting groove that matches the auxiliary support bolt 251 is drilled using a small drilling rig, and the auxiliary support bolt 251 is passed through the auxiliary support seat 25 and installed into the auxiliary support mounting groove to achieve fixation between the auxiliary support device 2 and the rock. In this way, a triangular stable structure is formed by connecting the top connecting frame 22, the bottom connecting frame 23 and the entire drilling and injection device 1, further improving the stability of the drilling and injection device 1. Step 3: Turn on the second motor 126 to control the driving horizontal shaft 1251 to rotate, thereby driving the transmission gear 125 to drive the transmission gear ring 124 and the driving cylinder 123 to rotate at high speed, thereby driving the drilling long tube 31, the drill bit 34 and the grouting inner cylinder 32 to rotate at high speed, and cooperate with the first motor 132 to drive the translation screw 131 to rotate, driving the movable bracket 14 to slide translationally on the outside of the guide cross bar 13 toward the side position of the second seat 121, controlling the drilling long tube 31, the drill bit 34 and the grouting inner cylinder 32 to translate into the rock together, and automatically perform deep drilling processing on the rock until the grouting hole processing is completed; Step 4: Install the connecting hose 37 on the connecting elbow 361 and connect the connecting hose 37 to the output port of the grouting pump mechanism. The pressure and flow rate of the grouting pump mechanism will automatically adjust according to the different permeability of the rock. Remove the inner deep insertion rod 35 from the threaded inner groove 323, and pass the extension rod 41 and the positioning block 42 through the elongated groove 301 and movably engage them in the drilling long tube 31, and make the positioning block 42 contact the outer end of the grouting inner cylinder 32; Subsequently, the first motor 132 is turned on to drive the translation screw 131 to rotate in the opposite direction, thereby driving the movable bracket 14 to slide in the opposite direction on the outer side of the guide crossbar 13 toward the side of the first seat 111, thereby controlling the drilling tube 31 to slowly move in the opposite direction and leave the grouting hole. At the same time, the hand-held rod 43 is manually pressed, and the head of the grouting inner tube 32 gradually extends out of the drilling tube 31 and the drill bit 34, preventing the grouting inner tube 32 from leaving the grouting hole along with the drilling tube 31. At the same time, the grouting pump mechanism and valve 36 are turned on to deliver slurry of appropriate pressure and flow rate into the grouting inner tube 32, and the slurry is gradually discharged from the inner position of the grouting hole through the grouting groove 321 at the head. While grouting, the long drilling tube 31 slowly separates from the grouting hole. The long drilling tube 31 will always support the grouting hole during the grouting operation to prevent some high-permeability rocks from causing hole wall collapse or slag leakage, resulting in hole blockage or premature loss of slurry. When the long slot 301 is moved reversely to the valve 36 near the end of the drill bit 34, the grouting operation is completed, then the grouting is stopped, the valve 36 is manually removed, and the plug 52 is screwed into the connector 322 to prevent the grout from leaking through the connector 322 before it solidifies; Then, the positioning block 42 continues to abut against the outer end of the grouting inner cylinder 32, the drill hole long pipe 31 and the drill bit 34 continue to be controlled to move outward until the drill hole long pipe 31 and the drill bit 34 are completely removed from the grouting hole, at this time, the grouting inner cylinder 32 is left in the grouting hole, and the grouting inner cylinder 32 is completely separated from the drill hole long pipe 31; Step five, remove the fixing bolt 151, and remove all parts of the drill and grouting device 1 from the rock grouting position except the grouting inner cylinder 32, the inner cover 33, and the limiting ring 324; At this time, the limiting ring 324 is exposed outside the rock, then the support disc 5 is installed at the end of the grouting inner cylinder 32 near the limiting ring 324, and the support nut 51 is screwed, then the fixing bolt 151 is installed in the original remaining positioning slot and matched with the corresponding fixing slot 501 to fix the support disc 5, thereby conveniently fixing the grouting inner cylinder 32; Thus, the rock drilling and grouting integrated operation is realized.

At the same time, the hand-held rod (43) is manually pressed, and the head of the grouting inner tube (32) gradually extends out of the drilling tube (31) and the drill bit (34), thereby preventing the grouting inner tube (32) from detaching from the grouting hole along with the drilling tube (31); At the same time, the grouting pump mechanism and valve (36) are turned on to deliver slurry of suitable pressure and flow rate into the grouting inner tube (32), and the slurry is gradually discharged from the inner position of the grouting hole through the grouting groove (321) at the head. While grouting, the drilling long tube (31) slowly separates from the grouting hole. The drilling long tube (31) will always support the grouting hole during the grouting operation to prevent some high permeability rocks from collapsing or leaking slag, resulting in hole blockage or premature loss of slurry; Until the end of the long groove (301) close to the drill bit (34) moves in the opposite direction to the valve (36), the grouting operation is completed, and then the grouting is stopped, the valve (36) is manually disassembled, and the plug (52) is threadedly installed in the connector (322) to prevent the slurry from leaking through the connector (322) before solidification; Subsequently, the positioning block (42) continues to press against the outer end of the grouting inner tube (32), and the drilling tube (31) and the drill bit (34) continue to be controlled to move outward until the drilling tube (31) and the drill bit (34) are completely moved out of the grouting hole.
