Foundation piling device for curve building

Abstract

The invention belongs to the field of piling technologies, and particularly relates to a foundation piling device for a curve building. The device comprises piling units and connecting mechanisms, wherein a plurality of filing units are connected through the connecting mechanisms. According to the device, a deep well is constructed in the ground; a reinforcing steel bar fixing structure is mountedto the bottom of the well; the piling units are pressed inside from four sides of the deep well through an assisting device; after the filing units are exposed from the bottom of the deep well, reinforcing steel bars are fixed to the reinforcing steel bar fixing structure; when rotating pipes of the piling units are driven to synchronously rotate through a motor, and rotating dumping arc plates can perform hole expanding; after hole expanding, the motor stops driving, and the dumping arc plates are contracted into a housing; then the piling units are pulled out through the assisting device, and cement is poured into the cement pipe at the same time; and finally cement which can completely cover the reinforcing steel bar fixing structure is poured into a big circular well; and the well isfilled with soil after cement is pouring. The pile foundation which is formed by a plurality of arc-shaped piles connected to the lower end meets the high building demands.

Description

Technical field [0001] The invention belongs to the technical field of piling, and in particular relates to an arc-shaped building foundation piling equipment. Background technique [0002] At present, in the field of pile foundation technology, the building pile forming equipment is generally round piles. As the buildings become taller and taller, the requirements for the strength of the pile foundation become higher and higher. If the traditional round piles want to meet the requirements, they need to drive the piles. Is deeper and increases the density of the pile. On the one hand, this will use more building materials and increase costs. On the other hand, it is not conducive to the improvement of building efficiency. Therefore, it is necessary to design a device without increasing the cost and reducing the density. [0003] The invention designs an arc-shaped building foundation piling equipment to solve the above problems. Summary of the invention [0004] In order to solve ...
