Soil foundation star-shaped center and arm end multi-cable anti-uplift foundation and construction method thereof

Abstract

The invention relates to a soil foundation star-shaped center and arm end multi-cable anti-uplift foundation. The soil foundation star-shaped center and arm end multi-cable anti-uplift foundation comprises a star-shaped component, a plurality of beard and hair anchor rods, base plates and anchor plates, wherein the star-shaped component is embedded into a soil foundation and the upper surface of the star-shaped component is higher than the ground; and the base plates and the anchor plates are matched with the beard and hair anchor rods. The star-shaped 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-shaped component. The outer end of each extended arm is provided with an anchor rod hole II. The center of each base plate is provided with an anchor rod hole III. The bottom ends of the multiple beard and hair anchor rods are all anchored, and the top ends of the beard and hair anchor rods penetrate through the anchor rod hole I or the anchor rod holes II of the star-shaped component and the anchor rod holes III of the base plates to be connected together with the corresponding anchor plates. The beard and hair anchor rods are composed of tension thin wires. Water-resistant explosives filled with detonators are bundled on the lower portions of the corresponding tension thin wires, and the tension thin wires are evenly distributed on the peripheries of the water-resistant explosives filled with the detonators in the perimeter direction. The invention further discloses a construction method of the soil foundation star-shaped center and arm end multi-cable anti-uplift foundation. According to the soil foundation star-shaped center and arm end multi-cable anti-uplift foundation and the construction method thereof, the structure is simple, investment is reduced and the amount of waste soil is small.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to a star-shaped center and arm end multi-cable pullout foundation of the soil 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...
