Abstract

The invention relates to an anchor rod-ball-starlike component foundation. The anchor rod-ball-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, a chassis arranged at the lowermost end of the rod body and a plurality of supporting rods hinged to the lower portion of the rod body; a waterproof explosive provided with a detonator is mounted under each chassis, and the multiple supporting rods are bound on the periphery of the corresponding waterproof explosive; the bottoms of the anchor rods, the chassis 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 remarkably reduced, and spoil is reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to an anchor rod-ball-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. Con...
