Anchor rod-upper plate-ball foundation and construction method thereof

Abstract

The invention relates to an anchor rod-upper plate-ball 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, backing plates and anchors matched with the anchor rods 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 rods hinged with the lower part of the rod body; the joint between the rod body and several rods is The water-resistant explosive with detonator is installed around the top, and several support rods are turned over to the upper end of the rod body and bound around the water-resistant explosive; the length of the support rod is greater than the radius of the cavity at the bottom of the hole, and greater than the distance between the rod body and the rod hinge. The length of the bottom end; the bottom end of the anchor rod and several support rods are anchored, and the top ends respectively pass through the anchor rod hole I at the corresponding position of the upper plate, and pass through the anchor rod hole III of the backing plate to connect with the anchor plate. The invention also discloses a construction method of the foundation. The invention has a simple structure, fundamentally changes the construction and foundation form, saves investment and reduces spoil.

Description

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