Upper plate-anchor rod-ball foundation and construction method thereof

Abstract

The invention relates to an upper plate-anchor rod-ball foundation. The upper plate-anchor rod-ball foundation comprises an upper plate embedded in a soil foundation, one or more anchor rods, cushion plates matched with the anchor rods, and anchor plates matched with the anchor rods, wherein the upper surface of the upper plate is flush with the ground. The upper plate is in a polygon shape, and first anchor rod holes are formed in the center of the upper plate. A third anchor rod hole is formed in the center of each cushion plate. Each anchor rod comprises a rod body and a plurality of support rods hinged to the bottom end of the rod body, strip-shaped waterproof explosive with a detonator is arranged around the lower portion of the rod body, and the multiple support rods are bundled to the periphery of the waterproof explosive. The bottom ends of the anchor rods and the multiple support rods are anchored, the top ends of the anchor rods penetrate the first anchor rod holes in the corresponding positions of the upper plate and penetrate the third anchor rod holes of the cushion plates to be connected with the anchor plates together. The invention further discloses a construction method of the foundation. According to the upper plate-anchor rod-ball foundation and the construction method of the foundation, the structure is simple, the construction and foundation form is basically changed, the investment is obviously saved, and abandoned soil is reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to an upper plate-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. Contents of ...
