Ball-anchor rod-upper plate foundation and construction method thereof

Abstract

The invention relates to a ball-anchor-upper plate foundation, which comprises an upper plate embedded in the soil foundation and whose upper surface is flush with the ground, one or more anchor bars, backing plates and anchors matched with the anchor bars 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 and several support rods; the lower part of the rod body is provided with a steel circular horizontal plate, the circle A plurality of hinge supports for the hinge connection of several poles and the circular horizontal plate are distributed around the rod body on the shaped horizontal plate; water-resistant explosives equipped with detonators are arranged around the rod body on the circular horizontal plate, and several support rods Turn over to the upper end of the rod body and bind it around the water-resistant explosive; the bottom end of the anchor rod and several support rods are anchored, and the top ends pass through the anchor rod hole I at the corresponding position on the upper plate and through the anchor rod hole on the backing plate Ⅲ is connected with the anchor plate. The invention also discloses a construction method of the foundation. The invention has simple structure, 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-bolt-upper plate 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...
