Abstract

The invention relates to the technical field of high-altitude drilling operation, in particular to a modularized quick-connection vibroflotation guide rod and a use method thereof, which comprises an upper guide rod and a lower guide rod, the bottom end of the upper guide rod is provided with a male connector assembly, the male connector assembly comprises a male connector main body and a connecting ring sleeved outside the male connector main body in a rotating mode, and the connecting ring is provided with a clamping piece in a protruding mode. An axial guide key groove and an L-shaped guide groove are arranged in the female joint body of the lower guide rod. The axial guide key slot limits the rotation of the male connector main body during the insertion, ensures the pure axial blind insertion of the internal pipeline, and meanwhile, the clamping piece slides in along the L-shaped guide slot to force the adapter ring to radially rotate and match with the inner conical surface and the outer conical surface to realize zero-clearance locking. When the pipe is pulled out, the unlocking sliding sleeve is pulled upwards in a straight line, the sliding pin forces the clamping piece to rotate backwards for unlocking, and meanwhile, the internal micro-channel one-way valve is triggered to introduce high-pressure fluid to wash sediment. The invention realizes dynamic and static separation and manual-free one-key unlocking in the plugging process, and greatly improves the reliability and efficiency of ultra-deep vibroflotation construction.

Description

Modularized quick-connection vibroflotation guide rod and application method thereof Technical Field The invention relates to the technical field of high-altitude drilling operation, in particular to a modularized quick-connection vibroflotation guide rod and a use method thereof. Background The traditional integral pile machine is adopted to carry out high-altitude or ultra-deep vibroflotation construction, and the defects that transportation is extremely difficult, cost is high, and special hoisting equipment is highly dependent are overcome. In order to solve the pain point, the prior art proposes to carry out modularized sectional design on a guide rod, and carry out on-site assembly in a flange or quick joint mode, so that short joint transportation and light equipment hoisting are realized. Compared with the traditional flange bolt splicing, the quick connector is adopted, so that the field construction efficiency is greatly improved, and the quick connector becomes an important development direction for improving ultra-deep vibration punching equipment. However, existing modular quick connect guides expose the following major drawbacks in actual severe vibroflotation construction. Firstly, in order to realize ultra-deep construction, pipeline modules such as a cable, a high-pressure water pipe, an air pipe and the like must be integrated inside the guide rod. The existing quick connector requires the two sections of guide rods to rotate relatively when being locked, if the guide rods are firstly abutted to the pipeline and then rotated, the internal pipeline can twist and wind, the layout and the leads of the pipeline are affected, and the heavy equipment is required to be used for rotating and screwing, so that the construction time and the operation difficulty are increased. Secondly, the vibroflotation device can produce tens tons of high-frequency transverse exciting force when working, and the existing quick-connection clamping block usually has a tiny assembly gap after being inserted, and the joint can be quickly fatigued and even broken by shattering under severe vibration. If zero-clearance rigid connection is to be realized, workers often need to use a large hammer to laterally strike or screw a large pipe wrench on site, and the operation is complex and potential safety hazards exist. In addition, when the ultra-deep silt layer is pulled out, silt can be extruded into the slot clearance of the joint to be hardened under the high pressure. The existing quick-connection structure lacks self-cleaning capability, so that the clamping block can not smoothly withdraw and unlock during tube drawing, the work efficiency is extremely low, and even the clamping rod can only be scrapped and cut integrally.
