Abstract

The invention relates to a star component-anchor rod-ball foundation. The star component-anchor rod-ball foundation comprises a star component, one or more anchor rods, base plates and anchor plates, wherein the star component is embedded into a soil foundation and the upper surface of the star component is flush with the ground; and the base plates and the anchor plates are matched with the anchor rods. The star component is provided with a plurality of extended arms which extend out in the radial direction, and an anchor rod hole I is formed in the center of the star component. An anchor rod hole III is formed in the center of each base plate. Each anchor rod comprises a rod body and a plurality of support rods hinged to the lower portion of the rod body. Water-resistant explosives with detonators are installed around the lower portions of the rod bodies of the multiple anchor rods, and the multiple support rods are bundled around the water-resistant explosives. The bottom ends of the anchor rods and the multiple support rods hinged to the anchor rods are all anchored onto an expanded head, and the top ends of the anchor rods penetrate through the anchor rod hole I in the corresponding position of the star component and the anchor rod holes III of the base plates to be connected with the corresponding anchor plates together. The invention further discloses a construction method of the star component-anchor rod-ball foundation. According to the star component-anchor rod-ball foundation and the construction method thereof, the structure is simple, investment is reduced and waste soil is also reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to a star-shaped component-bolt-ball 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...
