Problems solved by technology

[0005] Currently, the commonly used methods are high-pressure rotary spraying method, pressure grouting method, preloading method and artificial bottom cleaning method. Among them, high-pressure rotary spraying method, pressure grouting method and preloading method are all post-reinforcement measures, which have an impact on the construction period. Larger and more expensive
The manual bottom cleaning method has a harsh operating environment, the safety of workers cannot be guaranteed, and it is impossible to clean small-diameter piles and sediment generated when lowering the reinforcement cage
At present, there is no special equipment that can be used for cleaning the bottom of bored piles in the previous dry operation

Embodiment Construction

[0018] The air-flow type cleaning device for bored piles in dry operation includes a cylinder body 1, a motor 2, an air duct 3, a machine base 7, a stirring rod 9, a soil barrier 10, and connecting pieces.

[0019] Such as Figure 1 to Figure 5 As shown, the cylinder 1 is composed of a conical tube, a cylindrical tube, and a spherical bottom. The cylinder 1 has a conical tube at one end of the cylindrical tube and a spherical bottom at the other end. The material of the cylinder 1 is specific It is made of steel, and the cylindrical body 1 is provided with an organic seat 7 inside the connection between the cylindrical tube and the spherical bottom. The cylindrical body 1 is provided with a soil barrier 10 on one side of the internal machine seat 7. The said machine seat 7. There are motors 2 evenly distributed thereon. The motor 2 has a keyway at the end of its main shaft. One end of the main shaft of the motor 2 runs through the thin wall of the base 7 and the spherical bott...

Abstract

An air-flow type bottom-clearing device for dry-work bored piles relates to the technical field of dry-work bottom-cleaning equipment for bored piles, in particular to an air-flow bottom-cleaning device for dry-work bored piles, including a cylinder body (1), a motor ( 2), air duct (3), machine base (7), stirring rod (9), soil barrier (10), connecting piece, it is characterized in that cylinder (1) is made of conical tube, cylindrical tube, spherical bottom Composition, the cylindrical tube (1) is provided with a tapered tube at one end and a spherical bottom at the other end, and the cylindrical tube (1) is provided with an organic seat (7) inside the connection between the cylindrical tube and the spherical bottom , the cylinder (1), one side of the inner base (7) is provided with a soil barrier (10), the base (7) is evenly distributed with motors (2), and the The motor (2) is provided with a keyway at the end of its main shaft, and one end of the main shaft of the motor (2) passes through the thin wall of the base (7) and the spherical bottom of the cylinder (1) in turn.

Description

technical field [0001] The invention relates to the technical field of bottom-cleaning equipment for bored piles in dry operation, in particular to an air-flow type bottom-cleaning device for bored piles in dry operation. Background technique [0002] In recent years, with the rapid development of my country's national economy, the rapid increase of long-span bridges, port terminals, marine engineering and a large number of high-rise and super high-rise buildings has put forward high requirements and challenges for the design and construction of the foundation. [0003] The cast-in-situ pile foundation has the advantages of small settlement deformation, high bearing capacity and stable properties. It is suitable for any stratum and can form the pile diameter and pile length required by the design to meet the different bearing capacity requirements of buildings. It is applied in the form of modern foundation structures. The number has increased sharply, and currently accounts...
