High-pressure rotary spraying same-diameter rotary stirring mechanism and composite rigid pile all-in-one machine

Abstract

The invention relates to a high-pressure rotary spraying same-diameter rotary stirring mechanism and a composite rigid pile all-in-one machine, and belongs to the field of building construction. The high-pressure rotary spraying same-diameter rotary stirring mechanism comprises a first drill rod, a first power device for driving the first drill rod to rotate, a pressurizing device for driving thefirst drill rod to pressurize a construction surface and a stirring device arranged on the end portion of the first drill rod. The stirring device comprises a plurality of stirring blades positioned at the outer periphery of the end portion of the first drill rod, the high-pressure rotary spraying same-diameter rotary stirring mechanism further comprises a plurality of rotary spraying pipelines arranged in the first drill rod and a plurality of high-pressure nozzles arranged on the outer periphery of the first drill rod or the stirring blades. The high-pressure nozzles communicate with the rotary spraying pipelines. The high-pressure rotary spraying same-diameter rotary stirring mechanism can realize dry construction and same-diameter stirring. The invention further relates to the composite rigid pile all-in-one machine. By adopting the composite rigid pile all-in-one machine, the bearing capacity of a single pile is remarkably improved, the technical problem of difficulty in insertingrigid piles is solved, and the requirement on the bearing capacity of a construction site is remarkably reduced.

Description

technical field [0001] The invention relates to a pile foundation construction tool for high-rise, super-high-rise buildings and other buildings that require high pile foundation bearing capacity, and relates to a high-pressure rotary spraying and same-diameter rotary stirring mechanism and a composite pile integrated machine. Background technique [0002] All kinds of cement-soil composite piles that exist at present require the cooperation of multiple equipment, and the efficiency is low. The concentricity between the peripheral cement-soil piles and the internal rigid piles is insufficient, and the construction quality cannot be guaranteed. After the construction of cement-soil piles is completed, due to technological limitations, rigid piles cannot be constructed in time, which will cause a series of problems such as difficulty in pile pressing. [0003] CN108316293A discloses a cement-soil deep-layer mixing piling machine, its structure includes a driver, a drill pipe, ...

Problems solved by technology

The pile driver disclosed in this patent can reduce energy consumption, improve construction efficiency, have no noise, no pollution, and no vibration, but this pile driver cannot complete the pile driving work alone

[0004] CN108149689A discloses a pneumatic mobile pile driver, the pile driver includes a pile driving mechanism installed on the workbench, the pile driving mechanism is connected to the fixed part on the right side, the fixed part is connected to the hydraulic cylinder through the hydraulic rod, the hydraulic cylinder is connected to the hydraulic box, and the hydraulic box A pressurized box is installed on the right side, and a pressurized tube is installed on the pressurized box. The pressurized tube is connected to the top column of the piling mechanism through the air pressure port. A piston is installed in the piling mechanism, and a motor is installed under the piston. The motor passes through the connecting piece Connect the transmission shaft, the transmission shaft is connected to the working head, the chassis is installed under the workbench, and the rollers are installed on the front and rear sides of the chassis. The pneumatic mobile pile driver disclosed in this patent can carry out continuous and efficient piling operations on the designated target at the designated position through the piling mechanism , to ensure the piling effect and to be able to move and adjust flexibly through the rollers, but it does not have the ability to complete the piling work alone
