Embodiment Construction

[0040] Such as Figure 1~4 Shown, a kind of upper board-anchor-ball foundation, it comprises an upper board 6 embedded in the soil foundation 1 and the upper surface is flush with the ground 17, one or more anchor rods 4 and matching with the anchor rods 4 Backing plate 7 and anchor plate 8.

[0041] The upper plate 6 is polygonal (polygons include triangles, quadrilaterals, ...), with an anchor hole I in the center; an anchor hole III in the center of the backing plate 7; the anchor 4 includes a rod body and a number hinged with the bottom end of the rod body. Root pole 11; Bar-shaped anti-water explosive 12 with detonator 10 is installed around the bottom of the pole body, and several poles 11 are bundled around the water-resistant explosive 12; The bottom end of anchor rod 4 and several poles 11 are all covered Anchoring, the top ends of which respectively pass through the anchor hole I at the corresponding position of the upper plate 6, and pass through the anchor hole II...

Abstract

The invention relates to an upper plate-anchor rod-ball foundation. The upper plate-anchor rod-ball foundation comprises an upper plate embedded in a soil foundation, one or more anchor rods, cushion plates matched with the anchor rods, and anchor plates matched with the anchor rods, wherein the upper surface of the upper plate is flush with the ground. The upper plate is in a polygon shape, and first anchor rod holes are formed in the center of the upper plate. A third anchor rod hole is formed in the center of each cushion plate. Each anchor rod comprises a rod body and a plurality of support rods hinged to the bottom end of the rod body, strip-shaped waterproof explosive with a detonator is arranged around the lower portion of the rod body, and the multiple support rods are bundled to the periphery of the waterproof explosive. The bottom ends of the anchor rods and the multiple support rods are anchored, the top ends of the anchor rods penetrate the first anchor rod holes in the corresponding positions of the upper plate and penetrate the third anchor rod holes of the cushion plates to be connected with the anchor plates together. The invention further discloses a construction method of the foundation. According to the upper plate-anchor rod-ball foundation and the construction method of the foundation, the structure is simple, the construction and foundation form is basically changed, the investment is obviously saved, and abandoned soil is reduced.

Description

technical field [0001] The invention relates to soil foundation reinforcement and foundation forms, in particular to an upper plate-bolt-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. Contents of ...
