Description

Technical Field

[0001] The invention relates to the technical field of civil engineering tunnel construction, in particular to a backward segmented grouting device and a use method thereof. Background Art

[0002] During the construction of tunnels and underground projects, soft and water-rich strata are often encountered, which are prone to sudden water and mud gushing from the excavation surface and large deformation, endangering the safety of tunnel construction. At present, the grouting method of retreating segmented grouting equipment is often used to improve the properties of the surrounding rock. That is, cementitious materials are injected into the surrounding rock and consolidated under a certain pressure, filling the pores and compacting the soil, which has a good reinforcement and water blocking effect.

[0003] According to the announcement number CN110529155A, a drill bit stopping drill rod segmented backward grouting method is disclosed, using a drill bit stopping drill rod segmented backward grouting device, the grouting device includes: a plurality of double-tube drill rods, each double-tube drill rod is axially drilled into the grouting hole in sequence, and each root is detachably connected; the inside of the borehole is defined as the front and the outside as the rear; the front end of the frontmost double-tube drill rod is connected to a single-channel drill bit.

[0004] The above technical scheme can be adopted to avoid the slurry solidification and locking the drill rod and the drill bit, and realize a convenient and fast drill rod retreat grouting process, which has low requirements on drilling equipment and low loss. However, in the above technical scheme, when using the retreat type segmented grouting equipment to perform drilling and grouting operations on the tunnel surrounding rock, the drill machine drives the drill rod and the drill bit to rotate and move to drill holes in the tunnel surrounding rock. Since the retreat type segmented grouting equipment can only facilitate the connection, installation and drive of multiple sections of drill rods, but cannot limit the vertical position of the longer drill rod drilling, when installing multiple sections of drill rods, it is easy to deflect, which will not only cause the drilling deviation, but also easily cause the drill rod to bend and damage, thereby affecting the construction operation of the retreat type segmented grouting equipment, and the connection of multiple drill rods is relatively complicated, and it is not convenient to install and disassemble multiple drill rods, which further affects the construction operation of the retreat type segmented grouting equipment.

[0024] The movement of the extrusion plate can be limited by two sets of telescopic rods, thereby improving the clamping stability of the clamping plate on the drill rod.

[0025] A method for using a backward segmented grouting device comprises the following steps:

[0026] S1: When in use, first connect the device drive motor and the electric hydraulic pump to the power supply.

The outer surface of 205 is fixed with a hydraulic bag 6, and a delivery pipe 8 can be used to fill the hydraulic bag 6 with liquid, so as to facilitate the expansion of the hole drilled by the drill rod, thereby facilitating the pulling of the drill rod outward, and conveniently conveying slurry into the drilled hole through the grouting pipe 9, so as to perform segmented grouting operation on the sample layer through the movement of the drill rod, and a slurry cylinder 11 is used to store the slurry for grouting, and a filling liquid cylinder 10 is used to store the filling liquid for filling the hydraulic bag 6, and a first liquid adding pipe 16 is used to conveniently add filling liquid into the filling liquid cylinder 10, and a second liquid adding pipe 17 is used to conveniently add slurry for grouting into the slurry cylinder 11, and finally two output pipes 12 are respectively connected with the delivery pipe 8 and the grouting pipe 9, and the liquid in the slurry cylinder 11 and the filling liquid cylinder 10 can be conveyed through the electric hydraulic pump 13;

[0060] S2: During use, when the backward segmented grouting device is needed to perform segmented grouting on the rock formation, the device is first driven by the motor 1 to make the positioning frame 302 fixed by the support column 301 on one side of the device driving motor 1 close to the rock formation stone 304 that needs segmented grouting, and the positioning screw 306 in the positioning threaded barrel 303 can be manually twisted to make the positioning screw 306 close to the rock formation stone 304 and inserted into the positioning hole 305, so that the positioning frame 302 can be easily installed on one side of the rock formation stone 304, so that the clamping and positioning mechanism 4 can stably clamp and fix the second extended drill rod 206, and then the drill bit 7 can be driven by the device driving motor 1 to rotate and move, so as to facilitate the use of the drill bit 7 to drill holes 5 in the rock formation stone 304, thereby facilitating the segmented grouting operation;

[0061] S3: When the backward segmented grouting equipment is used to perform segmented grouting operations on rock formations, two sets of support legs 14 and support plates 15 are first used to form a support structure, which can stably support the equipment in a required position. The movable threaded column 404 in the threaded barrel 403 is manually twisted and clamped, so that the movable threaded column 404 can rotate in the limit block 406, and the two extrusion plates 407 can be pushed closer. The movement of the extrusion plates 407 can be limited by two sets of telescopic rods 18. Thereby, the clamping stability of the drill rod by the clamping plate 405 can be improved. Since the clamping plate 405 connected by the compression spring 409 is in contact with the outer surface of the second extended drill rod 206, the second extended drill rod 206 can be clamped by the elastic force in the compression spring 409. By bringing the two extrusion plates 407 closer, the elastic force in the compression spring 409 can be increased to improve the clamping stability of the second extended drill rod 206 by the structure, thereby reducing the problem of deflection of the drill rod and reducing the risk of bending and damage to the drill rod.

[0062] The working principle of the present invention is as follows: when in use, firstly connect the equipment driving motor 1 and the electric hydraulic pump 13 to the power supply. When it is necessary to use the backward segmented grouting equipment to perform segmented grouting operations on the rock formation, firstly drive the first extension drill rod 201 to rotate and move it into the rock formation through the equipment driving motor 1, and use the positioning column 203 fixed outside the connecting sleeve 202 to be clamped into the clamping groove 204, and make the connecting sleeve 202 clamped into the first extension drill rod 201, the second extension drill rod 206 and the rotating drill rod 205, so that the first extension drill rod 201, the second extension drill rod 206 and the rotating drill rod 205 can be connected, which not only facilitates the disassembly and assembly of the connection structure, but also facilitates and stably uses the backward segmented grouting equipment to perform segmented grouting operations on the rock formation. The rock formation is drilled and grouting is performed in sections. By fixing a hydraulic bag 6 on the outer surface of a rotating drill rod 205, the delivery pipe 8 can be used to fill the hydraulic bag 6 with liquid to facilitate the expansion of the hole drilled by the drill rod, thereby facilitating the pulling of the drill rod outward. The grouting pipe 9 is used to facilitate the delivery of slurry into the drilled area, so that the sample layer can be grouting in sections through the movement of the drill rod. The slurry for grouting is stored in the slurry cylinder 11, and the filling liquid cylinder 10 is used to store the filling liquid for filling the hydraulic bag 6. The first liquid adding pipe 16 is used to facilitate the addition of filling liquid to the filling liquid cylinder 10, and the second liquid adding pipe 17 is used to facilitate the addition of slurry for grouting to the slurry cylinder 11. Finally, two output pipes 12 are respectively connected to the delivery pipe 8 and the grouting pipe 9, which can The liquid in the slurry cylinder 11 and the filling liquid cylinder 10 is transported by the electric hydraulic pump 13. When in use, when it is necessary to use the retreat type segmented grouting equipment to perform segmented grouting operations on the rock formation, the equipment is first driven by the motor 1 to make the positioning frame 302 fixed by the support column 301 on one side of the equipment driving motor 1 close to the rock formation stone 304 that needs segmented grouting, and the positioning screw 306 in the positioning threaded cylinder 303 can be manually twisted to make the positioning screw 306 close to the rock formation stone 304 and inserted into the positioning hole 305, so that the positioning frame 302 can be easily installed on one side of the rock formation stone 304, so that the clamping and positioning mechanism 4 can stably clamp and fix the second extension drill rod 206, and then the equipment is driven by the motor 1 to drive the motor 1 to drive the motor 1. The driving motor 1 can drive the drill bit 7 to rotate and move, so as to facilitate the use of the drill bit 7 to drill holes 5 in the rock stratum stone 304, thereby facilitating the segmented grouting operation. When in use, when it is necessary to use the retreating segmented grouting equipment to perform segmented grouting operations on the rock stratum, firstly, two groups of support legs 14 and support plates 15 are used to form a support structure, which can stably support the equipment in a required position. By manually twisting the movable threaded column 404 in the clamping threaded cylinder 403, the movable threaded column 404 can be rotated in the limit block 406, and the two extrusion plates 407 can be pushed closer. Through the two groups of telescopic rods 18, the movement of the extrusion plate 407 can be limited, so as to improve the clamping stability of the clamping plate 405 on the drill rod.Since the clamping plate 405 connected by the compression spring 409 contacts the outer surface of the second extension drill rod 206, the second extension drill rod 206 can be clamped by the elastic force in the compression spring 409, and the elastic force in the compression spring 409 can be increased by the proximity of the two extrusion plates 407, thereby improving the clamping stability of the second extension drill rod 206 by the structure, thereby reducing the problem of deflection of the drill rod and reducing the bending damage of the drill rod.
