Technical Field
The utility model relates to an extrusion type grouting machine for geotechnical engineering slope support, in particular to a slurry splashing prevention device for the extrusion type grouting machine when a slurry conveying pipe is disassembled.
Background
Geotechnical engineering mainly studies the engineering characteristics of soil composition substances, and solves engineering problems of rock mass and soil mass, including foundation and foundation, slope and underground engineering and the like. Relates to a plurality of reinforcement modes such as side slope adding inherent grouting reinforcement, anchor rod reinforcement, soil nail reinforcement, prestressed anchor cable reinforcement and the like in side slope engineering. Wherein, the grouting reinforcement is to reinforce the slope body of the side slope by adopting pressure grouting. Under the action of pressure, grouting liquid permeates to the periphery through joint cracks cut around the wall of a drill hole, and plays a role in cementing broken slope rock-soil bodies to form a whole; in addition, the mortar column plays a role in bolt connection on the broken side slope rock-soil body, and the aim of improving the integrity and stability of the slope body is fulfilled.
The existing grouting equipment is an extrusion type grouting machine, when the existing grouting equipment is used for slope grouting reinforcement, a grouting pipe is adopted to connect a grout outlet pipe and a grouting pipe of the extrusion type grouting machine, the grouting pipe is inserted into a grouting hole and is fixed, the extrusion type grouting machine outputs grout from the grouting pipe through the grouting pipe, the grout permeates into the slope, and the slope is subjected to grouting reinforcement. After grouting, the slurry conveying pipe is generally detached from the slurry outlet pipe of the extrusion type grouting machine, then the slurry conveying pipe is gradually lifted upwards along the axial direction of the grouting pipe, and the residual slurry in the slurry conveying pipe is input into the side slope through the grouting pipe. At the moment of disassembling the slurry conveying pipe, because the slurry in the slurry conveying pipe still has certain pressure, the slurry can be sprayed out from the slurry conveying pipe opening along with the release of the pressure and splashed onto an operator, so that the operator is injured; meanwhile, the sprayed slurry cannot be recycled, which is a waste.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a device for preventing slurry from splashing when a slurry conveying pipe of an extrusion type grouting machine is disassembled.
The utility model provides a slurry splashing prevention device for an extrusion type grouting machine when a slurry conveying pipe is disassembled, which comprises a slurry conveying pipe, wherein one end of the slurry conveying pipe is in threaded connection with a slurry outlet pipe of the extrusion type grouting machine, and the other end of the slurry conveying pipe is connected with a slurry injection pipe; the outer side of the end part of the pulp conveying pipe connected with the pulp outlet pipe of the extrusion type grouting machine is sleeved with a protective pipe which has an aperture slightly larger than the outer diameter of the pulp conveying pipe and is telescopic in the axial direction, one end of the protective pipe is provided with a clamp which can be fixedly connected with the pulp outlet pipe of the extrusion type grouting machine, and the other end of the protective pipe is provided with a sleeve which can be in sliding connection with the outer wall of the pulp conveying pipe.
Further, the protective pipe is a threaded pipe made of elastic materials.
Furthermore, a flat slurry recycling cylinder which is communicated with the inner cavity of the threaded pipe and can be opened and closed along with the expansion of the threaded pipe is arranged below the middle part of the threaded pipe and used for recycling slurry sprayed out of the slurry conveying pipe when the slurry conveying pipe is detached.
Furthermore, paste on the inner wall of screwed pipe and thick liquid recovery section of thick bamboo and have the waterproof membrane for it hardens to effectively prevent that the cooling of screwed pipe and thick liquid recovery section of thick bamboo inner wall adhesion thick liquid back from influencing its life.
The working principle of the utility model is as follows:
before an extrusion type grouting machine is used for carrying out careful grouting reinforcement on an edge slope, the protective pipe is fixed at the end of the protective pipe on the outer wall of a grout outlet pipe of the extrusion type grouting machine by using a clamp at one end of the protective pipe, then the protective pipe is compressed to expose the pipe orifice of the grout outlet pipe, one end of a grout conveying pipe is in threaded connection with the grout outlet pipe of the extrusion type grouting machine, the compressed protective pipe is loosened, the protective pipe extends, and a sleeve at the other end of the protective pipe can be sleeved on the outer wall of the grout conveying pipe; and connecting the other end of the grout conveying pipe with the grouting pipe, inserting the grouting pipe into the drilled hole of the side slope and fixing, then opening the extrusion type grouting machine, injecting grout into rock soil around the drilled hole of the side slope through the grout outlet pipe, the grout conveying pipe and the grouting pipe under the pressure applied by the grouting machine, permeating into the side slope, and grouting and reinforcing the side slope. After the grouting is finished, the sleeve at the end part of the grout conveying pipe is held by one hand to be fixed, the grout conveying pipe is rotated by the other hand to be unscrewed from the grout outlet pipe of the grouting machine in threaded connection with the grout conveying pipe, when a puff sound is heard, the grout conveying pipe is separated from the grout outlet pipe of the grouting machine, and the grout sprayed out of the front end of the grout conveying pipe cannot be sprayed outwards and only can enter the inner cavity of the protective pipe because the two ends of the grout conveying pipe are in a closed state. If the lower part of the protective pipe is provided with the slurry recycling cylinder communicated with the protective pipe, the lower end of the slurry recycling cylinder is arranged in the slurry containing barrel, the protective pipe is extruded by pushing the sleeve at the other end of the protective pipe, so that the slurry entering the protective pipe can be discharged into the slurry containing barrel through the slurry recycling cylinder, and the purpose of recycling is achieved. Then, loosening the clamp at one end of the protective pipe to separate the protective pipe from a slurry outlet pipe of the grouting machine, and sliding the sleeve at the other end of the protective pipe out along the outer wall of the slurry conveying pipe to separate the protective pipe from the slurry conveying pipe; and lifting the slurry conveying pipe separated from the slurry outlet pipe of the slurry injector upwards gradually along the axial direction of the slurry injection pipe, so that the residual slurry in the slurry conveying pipe is conveyed into rock soil at the periphery of the side slope drill hole through the slurry injection pipe, and thus completing the slurry injection of one side slope drill hole.
By using the slurry splashing prevention device for the extrusion type grouting machine, the slurry splashing injury to operators can be effectively prevented when the slurry conveying pipe is detached; meanwhile, the slurry discharged from the slurry conveying pipe can be recycled, so that the waste of the slurry is reduced, and the side slope grouting reinforcement cost is favorably reduced.
