Standby to be made of weight, girder steel, jack etc., the common heavy object of heap is concrete balancing weight, and the self weight of equipment about designs pole
Limit 120% or more of bearing capacity；Anchored pile-testing method needs disposably vertically to squeeze into the pile foundation of several offer counter-forces.Implementing at this stage
During loading test, ballasting platform counterforce device need to transport a large amount of concrete balancing weights of installation, the equipment such as girder steel；Anchoring pile is anti-
Anchoring pile in power device not can be recycled, these cause a large amount of resource consumption, not meet that the whole society is environmentally protective, low-carbon energy-saving
The requirement of development.Based on the above issues, it is necessary to invent a kind of foundation pile static load test recyclable ground anchor counterforce device to reduce
Resource loss and testing cost meet the requirement of whole society's green, low-carbon, circular economy, Energy Conservation.
Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of foundation pile static load test recyclable ground anchor counter-force dress
It sets.
The utility model is achieved by the following technical solution: a kind of foundation pile static load test recyclable ground anchor counter-force dress
It sets, including column (1), stayed mast (2), steel ground beam (3), high tensile reinforcement (4) and expansion somatocyst bag (5), it is characterised in that: described

Specific embodiment
Below with reference to Fig. 1 to Fig. 3 and embodiment, the utility model is further described.
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
The high tensile reinforcement (4) of PSB high-strength finish rolling deformed bar, tensile strength reaches 1030Mpa, makes the technical advance and ring of earth anchor
