Description
Technical field
Foundation pile static loading test technical field is the utility model is related to, more particularly to a kind of anchored pile-testing method foundation pile static load that is applied to is tried
The anchor box counterforce device tested.
Background technology
When examining vertical ultimate bearing capacity of single pile with static load test, sending out bearing capacity of pile foundation existing has many more than needed, nothing
Substantial amounts of available resources are wasted in shape；Some bearing capacity of pile foundation do not reach design requirement, it is possible to are due to design or construction
Caused by quality etc..Some engineerings do not begin to construct by test pile static test, and it is hidden to bring safety to engineering
Suffer from, just in case bearing capacity is not reaching to design requirement, may have to take floor subtract layer processing, piling or change foundation pattern,
The measures such as inter-pile soil consolidation process, it is clear that huge economic losses can be caused, so pile foundation must carry out static test inspection
Vertical allowable load capacity of single pile.Foundation pile static loading test must be provided counter-force by counterforce device, during foundation pile static loading test
Counterforce device have anchoring pile counterforce device, ballasting platform counterforce device, anchoring pile ballast joint counterforce device, earth anchor counterforce device
Deng for wherein anchoring pile counterforce device using relatively broad, anchoring pile counter-force boom device is exactly by several geometrically symmetric around test pile
Anchoring pile is connected with dowel and reaction frame, jacks up reaction frame by the jack of stake top, is provided by connected anchoring pile anti-
Power.The size for providing counter-force is determined by the withdrawal resistance of anchoring pile quantity, reaction frame intensity and connected anchoring pile.Anchoring pile counter-force boom device
It will not typically be limited by field condition and loading tonnage number, not only accelerate engineering construction progress to a certain extent, improve
The security of test operation, and financial cost is greatlyd save, it is when conditions permit most as anchoring pile using engineering pile
It is economical, but need during experiment to observe anchoring pile on the amount of pulling out, in order to avoid pulling off or extracting, cause the destruction of engineering pile.Mesh
Preceding reaction frame and anchoring pile during anchored pile-testing method experiment carry out welding company mainly by " n " the shape reinforcing bar that site operation unit makes
Connect；According to multiple execute-in-place experience, the connection of such a " n " shape reinforcing bar because some " n " shape steel bar meters it is lack of standardization so that
Discontinuity, so elbow easily produces brittle failure in loading procedure, not only when often result in static test interruption, but also
Easily cause reaction frame to collapse and cause security incident.The utility model patent of Patent No. 201420814665.1 discloses one
A kind of kind of combination clamp plate type anchoring pile counter-force attachment means, the device include steel clamp, dowel plumb joint, combination beam, spiral,
Steel plate connection reinforcing bar, anchoring pile reinforcing bar；Its annexation is：Combination beam forms auxiliary girder with the spiral through combination beam gap；
Between by two connection reinforcement weldings steel clamp be placed on auxiliary girder, steel clamp is placed into the corresponding perspective plane position of anchoring pile,
Spiral is through steel clamp and rotates spiral, the dowel plumb joint on spiral is blocked steel clamp, spiral
Bottom is connected with anchoring pile reinforcement welding.The utility model small volume light weight is transported and storage is convenient, and uniform force safely may be used
Lean on, it is reusable, efficiency of construction is improved, but it is only suitable for combination beam, and independent secondary beam can not be used, and by two steel plates
The steel clamp of composition, which is stood on combination beam, to be tested, and easily is skidded to topple over because contact surface is smaller, during stress and is caused safety
Accident.
