Problems solved by technology
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

Embodiment Construction
[0042] Such as figure 1 Ball-upper plate-bolt foundation, it comprises an upper plate 6 embedded in the soil foundation 1 and the upper surface is flush with the ground 17, one or more anchor rods 4 and backing plates 7 matched with the anchor rods 4 and Anchor plate8.
[0043] 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, a sleeve 20 and several branches. Rod 11; the lower part of the rod body is fixedly connected with a steel circular horizontal plate 19, which is sleeved with a sleeve 20 sliding up and down along the rod body; one end of several poles 11 is hinged around the sleeve 20; between the sleeve 20 A water-resistant explosive 12 with a detonator 10 is installed around the upper rod body, and several support rods 11 are turned over to the upper end of the rod body and bound around the water-resistant exp...

The invention relates to a ball-upper plate-bolt 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 anchor rods 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, a sleeve and several support rods; the lower part of the rod body is fixedly connected with a steel circular horizontal A plate, which is covered with a sleeve that slides up and down along the rod body; one end of several rods is hinged around the sleeve; a water-resistant explosive with a detonator is installed around the rod body above the sleeve, and several 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-upper plate-bolt 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...
