Description

Technical Field

[0001] The invention relates to the technical field of foundation soil grouting construction, in particular to a foundation soil grouting reinforcement system. Background Art

[0002] Grouting is an engineering technology for improving soil properties by injecting slurry. It is widely used in foundation reinforcement construction and is an indispensable construction step in foundation construction. Grouting is mainly carried out using grouting drill equipment. Grouting drill is the core equipment in foundation grouting, mainly used for drilling and slurry injection. It drills the grouting drill rod into the soil and then injects slurry through the drill rod. The slurry can be cement slurry or chemical slurry, so that the slurry is mixed with the soil to improve the soil and achieve reinforcement. In this regard, the Chinese utility model patent with the authorization announcement number CN211008445U discloses a motor box, the inner cavity of the motor box is fixedly connected to a servo motor, and the bottom end of the servo motor output shaft is fixedly connected to a drill tool through a coupling. The bottom end of the drill tool passes through the motor box and extends to the bottom of the motor box. Sleeves are fixedly connected on both sides of the motor box surface, and the tops of the two sleeves are respectively penetrated by a first support frame and a second support frame. However, the current drilling equipment for foundation grouting has the following defects:

[0003] The above-mentioned drilling rig can only drill holes, and then install the grouting pipe before grouting. Therefore, a drill rod that can be used for direct grouting has appeared on the market. After the drill rig drills the drill rod into the hole, grouting can be performed directly through the drill rod. However, the current grouting drill rig cannot adjust the drilling angle of the drill rod. In many construction environments, the foundation surface is not flat, which causes the drill rod drilling route to be not vertical enough. During subsequent grouting, the slurry will flow more toward the soil on one side, affecting the reinforcement effect. In addition, the grouting drill rig is heavy, not easy to adjust the position, and not convenient to use.

[0004] To this end, we propose a foundation soil grouting reinforcement system to solve the above problems. Summary of the Invention

[0045] The slurry and water supply assembly 23 includes an internal threaded pipe 231, the top of the internal threaded pipe 231 is fixedly connected to and connected to the high-speed rotary joint 232, the top of the high-speed rotary joint 232 is fixedly connected to and connected to the riser 233, the top of the riser 233 is fixedly connected to and connected to the water injection elbow 234, the side wall of the riser 233 is fixedly connected to and connected to the grouting head 235, the internal threaded pipe 231 is threadedly connected to the threaded pipe head 21, and the grouting drill head assembly 24 includes an external threaded pipe 241, the bottom end of the external threaded pipe 241 is fixedly connected to and connected to the grouting pipe 242, the bottom end of the grouting pipe 242 is fixedly connected to the drill head 243, a plurality of slurry outlet holes 244 are evenly arranged on the circumference of the grouting pipe 242, and the external threaded pipe 241 is threadedly connected to the internal threaded part 22.

[0046] When the present invention is used, the grouting drill rod 2 is inserted into the cylindrical shell 17, and then the grouting drill head assembly 24 is installed at the bottom end of the grouting drill rod 2, and the grouting and water supply assembly 23 is installed at the top end of the grouting drill rod 2. Then, the verticality of the grouting drill rod 2 is tested using a plumbing device. If it is not vertical, the hydraulic push rod 114 drives the body 11 to adjust the angle, and the first drive motor 118 is used to adjust the rotation of the turntable 14, and then the rotation position of the column part 116 is adjusted until the grouting drill rod 2 is vertical. Then, the small hydraulic push rod 151 drives the arc-shaped tooth plate 150 to move upward to clamp the locking gear ring 147, and tighten the nut 145 to lock the position of the body 11. Then, the lifting platform 16 is raised to the highest point, and the hydraulic chuck assembly 18 clamps the grouting drill. Rod 2, then connect the water supply equipment to the water injection elbow 234, adjust the water supply, avoid the temperature at the grouting drill head assembly 24 is too high, then the second drive motor 133 is started to drive the grouting drill rod 2 to rotate, and then the lifting platform 16 moves down to drive the grouting drill rod 2 to press down, and drill until the lifting platform 16 completes its stroke, the hydraulic chuck assembly 18 releases the grouting drill rod 2, the grouting drill rod 2 stops rotating, the lifting platform 16 rises back to the highest point, and then the hydraulic chuck assembly 18 clamps the grouting drill rod 2 again to continue the drilling operation. If the length of a single grouting drill rod 2 is insufficient, after it is fully drilled in, remove the slurry and water supply assembly 23 on the top of the grouting drill rod 2, connect another grouting drill rod 2, and then The top of the grouting drill rod 2 is installed with a grouting and water supply assembly 23, which can achieve the effect of drilling holes connected with multiple grouting drill rods 2. After reaching the required depth, the output pipe of the grouting equipment is connected to the grouting head 235 to inject slurry. During injection, the hollow main shaft 130 drives the grouting drill rod 2 to rotate, so that the slurry is rotated and ejected at the slurry outlet hole 244. During grouting, the lifting platform 16 drives the grouting drill rod 2 to rise slowly. After the lifting platform 16 rises to the highest point, the hydraulic chuck assembly 18 releases the grouting drill rod 2, and the lifting platform 16 returns to the lowest point. The hydraulic chuck assembly 18 clamps the grouting drill rod 2 again and continues to lift slowly until the grouting drill rod 2 is completely lifted out, completing the grouting reinforcement construction. The present invention rotates the cylindrical shell 17 to complete the grouting reinforcement construction. The rotation of the turntable 14 can drive the rotation of the turntable 14, thereby adjusting the angle of the grouting drill rod 2 in one direction. The angle of the grouting drill rod 2 in the other direction can be adjusted by rotating the body 11 around the position of the side block 19. In this way, even if the foundation surface is uneven, the grouting drill rod 2 can be adjusted to a vertical direction, and drilling and grouting construction at different angles can be carried out as needed, which is more flexible; the carrier plate 45 in the base structure 4 can drive the drilling mechanism 1 to change the horizontal position, which can make it more convenient to adjust the position without moving the entire equipment, and is more convenient to use; the hydraulic chuck assembly 18 is the most easily damaged structure in the grouting drill rig. After removing the end cover 152, the hydraulic chuck assembly 18 can be easily removed as a whole.
