A high-stability drilling machine for cast-in-place piles

Abstract

The invention discloses a high-stability punching machine for a cast-in-place pile. The high-stability punching machine comprises a machine shell, a first stabilization assembly is arranged on the machine shell; the high-stability punching machine further comprises a punching device, and the punching device comprises a main pushing hydraulic clamping device, a driving mechanism and a transmission mechanism; a connecting steel plate is arranged on one side of the machine shell, the transmission mechanism is placed on the connecting steel plate, one end of the transmission mechanism is connected with an output shaft of a reducer, and the other end of the transmission mechanism is connected with the main pushing hydraulic clamping device; the first stabilization assembly extends out the machine shell to be connected with the main pushing hydraulic clamping device in an abutting mode; a high-stability assembly is arranged on the lower surface of the connecting steel plate, the high-stability assembly comprises an annular hose, the annular hose stores non-Newtonian fluid, and the annular hose sleeves the main pushing hydraulic clamping device and is located on the lower surface of the connecting steel plate; and the main pushing hydraulic clamping device is provided with a buffer block, and the buffer block is connected to the lower surface of the annular hose in an abutting mode. The high-stability punching machine has the effects of being high in stability, and being capable of timely buffering and reducing occurrence of failures.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a high-stability drilling machine for cast-in-situ piles. Background technique [0002] Cast-in-place pile is a kind of pile made by forming holes in place and pouring concrete or reinforced concrete. The commonly used ones are: 1. Drilled cast-in-place piles: use auger drilling rigs, diving drilling rigs, etc. to pour concrete into holes in situ to form piles. The submersible drilling rig is suitable for cohesive soil, sandy soil, silt and silty soil, etc., and is especially suitable for forming holes in soil layers with high groundwater levels. Use mud to protect the wall when drilling to prevent the hole from collapsing. Drilling in clay with clear water, self-made mud wall; in sand should be injected into the prepared mud drilling. Utilize the mud circulation to remove the soil debris from drilling. After drilling to the required depth, the hole should be cleared...

Problems solved by technology

Although this simple cast-in-situ pile hammer hole forming equipment is simple to operate, small and flexible, high in drilling efficiency, and has strong practicability, the impact force generated by hammering the cast-in-place pile is likely to cause damage to the cast-in-place pile. damage, resulting in the instability of the cast-in-situ pile structure, which leads to hidden dangers in construction
