Specific embodiment
Below with reference to Fig. 1 to Fig. 3 and embodiment, invention is further explained.
A kind of foundation pile static load test recyclable ground anchor counterforce device, including column (1), stayed mast (2), steel ground beam
(3), high tensile reinforcement (4) and expansion somatocyst bag (5) expand somatocyst bag (5) setting in the lower end of high tensile reinforcement (4), and high tensile reinforcement (4) is other
It is probeed into equipped with pressure pipe (8) lower end and expands three in somatocyst bag (5) and be driven underground jointly, the upper end of high tensile reinforcement (4) and be placed in ground
The steel ground beam (3) in face is connected by fixing end (9), and stayed mast (2) upper end connect with column (1), stayed mast (2) lower end and with
Be placed in ground steel ground beam (3) connection, expand somatocyst bag (5) can high companding body, high tensile reinforcement (4) and expand body after pouch
(5) combination, which is formed, expands body earth anchor.High tensile reinforcement (4) is using PSB high-strength finish rolling deformed bar.The material of pressure pipe (8)
It is stainless steel.Earth anchor is driven underground by proper angle, can give full play to the stress of the engineering ground underground soil body, has good warp
Ji property.Expanding somatocyst bag (5) pouch after high pressure is cancelled can shrink, and be convenient for recycling and reusing.The conduction of ground anchor structure power uses
