Abstract

The invention relates to a ball-anchor rod-starlike component foundation. The ball-anchor rod-starlike component foundation comprises a starlike component, one or more anchor rods, cushion plates matched with the anchor rods, and anchor plates matched with the anchor rods, wherein the starlike component is embedded into a soil foundation, and the upper surface of the starlike component is flush with the ground surface; the starlike component is provided with a plurality of extension arms extending in the radial direction, and an anchor rod hole I is formed in the center of the starlike component; an anchor rod hole III is formed in the center of each cushion plate; each anchor rod comprises a rod body and a plurality of supporting rods; a circular transverse steel plate is fixedly arranged at the lower portion of each rod body, and hinged supports used for hinging the supporting rods to the corresponding circular transverse steel plate are distributed on the circular transverse steel plate around the corresponding rod body; a waterproof explosive provided with a detonator is arranged on the periphery of the part, above the circular transverse steel plate, of each rod body, and the multiple supporting rods are overturned to the upper end of the corresponding rod body and bound to the periphery of the corresponding waterproof explosive; the bottom ends of the anchor rods and the supporting rods are anchored; and the top end of each anchor rod penetrates through the anchor rod hole I in the corresponding position of the starlike component and penetrates through the anchor rod hole III in the corresponding cushion plate to be connected with the corresponding anchor plate. The invention further discloses a construction method of the foundation. The structure is simple, the investment is reduced, and spoil is reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to a ball-bolt-star component foundation and a construction method thereof. Background technique [0002] At present, most of the foundations are compression foundations, that is, the foundation mainly bears the vertical load imposed by the superstructure and meets the deformation and stability requirements, typically including independent foundations, strip foundations, raft foundations, etc. The uplift-resistant foundation mainly includes large excavation foundation, excavation and bottom expansion foundation, explosive expansion pile foundation, etc. difficulty, and there are problems such as large amount of engineering, long time-consuming, high cost, great damage to the environment, but limited resistance and unsatisfactory reinforcement effect. The large deformation and the stability of the foundation become the key issues that must be solved. Contents o...
