AI Technical Summary
The existing drilling pile guard lacks symmetrical openings and effective support structures, resulting in problems of drilling errors and cartridge collapse.
The design of the guard is a circular opening around the guard, and steel pipes and vertical rods are installed inside. Combined with the sliding rods and spring structure, it realizes simple positioning and support of the guard, ensuring that the steel pipes can be snapped in and providing up and down movement support.
The center point of the guard is determined through multiple symmetrical openings to ensure that the steel pipe can effectively support the guard, avoid collapse, and increase the contact area through the arc-shaped bottom to reduce stress concentration.

Description
Technical Field
[0001] The utility model relates to the technical field of bored pile casings, in particular to a simple positioning and supporting structure on a bored pile casing. Background Art
[0002] In the implementation of bridge engineering, due to various reasons in the preliminary work, the bridge engineering may be implemented first, while the underground station intersecting with it is implemented later. However, the bridge pile foundation may fall on the components of the underground structure. However, from the perspective of structural force, it is unscientific and uneconomical to use the underground structure to bear the load of the bridge pile foundation. A more scientific method is to transfer the load of the bridge to the foundation through the poles or columns of the underground structure. The load of the bridge is transferred to the foundation through the pile foundation. Due to the existence of the underground structure, especially the station structure, the cross-section of the pole structure is smaller than that of the bridge pile foundation. In this way, there are different cross-sectional requirements for the pile foundation and the column or pole in the space of the underground structure.
[0003] However, there are still some problems when the existing casing is used:
[0004] There are still the following problems in actual use:
