Abstract

The invention relates to a ball-upper plate-anchor foundation, which comprises an upper plate embedded in the soil foundation and whose upper surface is flush with the ground, one or more anchor rods and a backing plate matched with the anchor rods and anchor plate. The upper plate is polygonal, with an anchor hole I in the center; an anchor hole III in the center of the backing plate; the anchor includes a rod body, a chassis at the bottom of the rod body, and the Several poles hinged at the lower part of the rod body; water-resistant explosives with detonators are installed under the chassis, and several poles are bound around the water-resistant explosives; the bottom end of the anchor rod and the The chassis and several of the support rods are all anchored, and their top ends respectively pass through the anchor hole I at the corresponding position of the upper plate, and pass through the anchor hole III of the backing plate and the anchor plate. connected together. The invention also discloses a construction method of the foundation. The invention has a simple structure, fundamentally changes the construction and foundation forms, significantly saves investment and reduces spoil.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to a ball-upper plate-bolt 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 t...
