Description

TECHNICAL FIELD

[0001] The utility model belongs to grouting drilling construction technical field, especially a kind of reusable drilling rig fixing device. BACKGROUND

[0002] The society is changing rapidly, and science and technology are advancing continuously, and the society is developing continuously, and the difficulty of water conservancy and hydropower engineering construction is also increasing, and the corresponding construction equipment facilities also need to be continuously updated, which has positive significance for social development. In the process of engineering construction, the construction quality standard is higher, the requirement is more stringent, and the construction process control is more perfect, so as to create a new industry image, vigorously promote standardization construction, continuously strengthen construction quality control and continuously improve quality management level.

[0003] Grouting drilling construction is an indispensable means for stratum foundation treatment in water conservancy and hydropower engineering, and deep-hole curtain grouting is an important foundation treatment technology for enhancing foundation anti-seepage, filling cracks and pores in rock-soil, preventing foundation seepage and improving overall strength and rigidity of rock-soil. With the continuous progress of science and technology, the construction standard of water conservancy and hydropower engineering is also strengthened, and the difficulty of deep-hole curtain grouting is also increased. In order to prevent foundation seepage and form water-blocking curtain, it is necessary to ensure the drilling accuracy of curtain grouting hole to ensure that the water-blocking curtain formed by curtain grouting can block the circulation of underground water, increase the strength of foundation and improve the overall strength of rock-soil.

[0004] Deep-hole curtain grouting generally uses geological drilling machine for drilling construction. Since the maximum depth of super-deep-hole curtain grouting hole is 224 meters, the conventional drilling machine fixing device cannot effectively control the shaking of drilling machine, so as to cause the deviation of drilling angle and affect the construction quality. The traditional drilling machine fixing device usually uses single mechanical clamp or chemical anchoring agent to fix the drilling machine. For example, some fixing devices only rely on bolts and gaskets to fix the drilling machine on the ground, and this way is not good on hard or soft foundation. If it is not fixed firmly, the drilling machine is easy to shake during work, which causes the deviation of drilling angle and affects the accuracy of drilling. Specifically, in order to ensure that the drilling angle is correct during drilling and ensure that the effect of deep-hole curtain grouting reaches the ideal state, the drilling speed is often reduced during deep-hole curtain grouting, and the drilling angle is frequently calibrated, which greatly increases the construction cost, such as additional labor, machinery, etc., and affects the construction efficiency.

[0030] In the embodiment, the centripetal extrusion assembly comprises an upper tight pressing sleeve end 5 sleeved on the upper part of the screw rod 3 and located at the top end of the screw rod outer tube 4, and a lower fixed sleeve end 6 sleeved on the lower part of the screw rod 3 and located at the bottom end of the screw rod outer tube 4.

[0031] In this embodiment, the conical sleeve 16 is pushed down by the pressure applied by the dynamic locking assembly to the upper tightening sleeve end 5, thereby expanding the upper opening 7 and the lower opening 8, improving the expansion efficiency, ensuring that the screw outer tube 4 can be quickly and firmly clamped on the inner wall of the anchoring hole, reducing the risk of equipment damage caused by uneven pressure. The conical sleeve 16 is integrally formed on one end of the upper tightening sleeve end 5 and the lower fixed sleeve end 6, respectively.

[0036] In this embodiment, one end of each steel wire rope 14 away from the ear ring 12 is fixed on the top end of the shrink port sleeve ring 11, and the rope body of the two steel wire ropes 14 is in the gap of the upper opening 7. When the upper opening 7 is stuck in the anchor hole, the steel wire rope 14 is prevented from being squeezed and worn, thereby improving the service life of the steel wire rope 14 and preventing the steel wire rope 14 from being stuck. The position design of the steel wire rope 14 avoids direct contact with the upper opening 7, reduces the risk of wear and tear, improves the service life of the steel wire rope 14, reduces the maintenance frequency, and ensures the long-term effectiveness of the shrink quick release assembly.

The outer diameter of the shrink port sleeve ring 11 is smaller than the diameter of the anchor hole, the shrink port sleeve ring 11 has a shrink friction wall 15 for upward friction contraction of the upper opening 7, and the shrink friction wall 15 is in sliding friction contact with the outer wall of the upper opening 7.
