Arc-shaped foundation pile forming device for municipal works

Abstract

The invention belongs to the field of pile driving, in particular to an arc-shaped foundation pile forming device for municipal works. The arc-shaped foundation pile forming device comprises a plurality of pile forming units and connecting mechanisms, wherein the pile forming units are connected together through the connecting mechanisms. According to the arc-shaped foundation pile forming devicedisclosed by the invention, firstly, a deep well is formed in the ground, a reinforcing steel bar fixing structure is laid on the bottom of the well, and the pile forming units are pressed in from allsides of the deep well through auxiliary equipment; after the pile forming units are exposed from the bottom of the deep well, reinforcing steel bars are fixed on the reinforcing steel bar fixing structure; then, rotating tubes in the pile forming units are driven to rotate simultaneously by a motor, chambering can be performed by rotating dumping arc plates, after chambering is finished, the motor stops driving, and the dumping arc plates shrink into a shell; and then, the pile forming units are pulled out through the auxiliary equipment, meanwhile, cement is injected into a cement tube, finally, cement capable of fully covering the reinforcing steel bar fixing structure in amount is injected into the large deep well, and the large deep well is filled and leveled up with soil after the cement is injected. A pile foundation which consists of a plurality of arc-shaped piles connected at the lower end can adapt to a higher construction demand.

Description

Technical field [0001] The invention belongs to the technical field of piling, in particular to a municipal arc-shaped foundation piling device. Background technique [0002] At present, in the field of pile foundation technology, the pile forming equipment for construction is generally a round pile. As the building becomes higher and higher, the strength requirements for the pile foundation are getting higher and higher. If the traditional round pile wants to meet the requirements, the pile needs to be driven deeper and increase the density of the pile. On the one hand, this will use more building materials and increase the cost. On the other hand, it is not conducive to the improvement of construction efficiency. Therefore, it is necessary to design a device without increasing the cost and reducing the density. [0003] The present invention designs a municipal arc-shaped foundation piling device to solve the above problems. Contents of the invention [0004] In order ...
