Problems solved by technology

The uplift-resistant foundations mainly include large excavation foundations, excavation and bottom expansion foundations, and explosive expansion pile foundations, etc. It is difficult, and there are problems such as large amount of engineering, long time consumption, high cost, great damage to the environment, limited resistance, and unsatisfactory reinforcement effect. The above problems are more prominent under the condition of the soil foundation, and the soil The large deformation and the stability of the foundation become the key issues that must be solved

Abstract

The invention relates to a soil foundation center and slab angle multi-cable anti-uplift foundation. The soil foundation center and slab angle multi-cable anti-uplift foundation comprises an upper plate, a plurality of beard and hair anchor rods, base plates and anchor plates, wherein the upper plate is embedded into a soil foundation and the upper surface of the upper plate is higher than the ground; and the base plates and the anchor plates are matched with the beard and hair anchor rods. The upper plate is a polygon, and the center and each angle of the polygon are each provided with an anchor rod hole I. The center of each base plate is provided with an anchor rod hole II. 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 holes I of the upper plate and the anchor rod holes II 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 center and slab angle multi-cable anti-uplift foundation. According to the soil foundation center and slab angle multi-cable anti-uplift foundation and the construction method thereof, the structure is simple, the construction and foundation modes are changed fundamentally, investment is reduced and waste soil is also reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to multi-cable uplift foundations at the center of the foundation and board corners 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. It is difficult, and there are problems such as large amount of engineering, long time consumption, high cost, great damage to the environment, limited resistance, and unsatisfactory reinforcement effect. The above problems are more prominent under the condition of the so...
