Description
Technical field
The present invention relates to a kind of construction equipment, more particularly to a kind of static load resistance to compression lotus experimental rig.
Background technology
The single pile resistance to plucking static test of pile foundation refers to apply upward vertical active force in stake top portion, observed in certain time
Under effect, uplift displacement caused by pile body entirety, to determine the test method of corresponding uplift bearing capacity.
Static load test is to determine most direct, most basic in all multi-methods of ultimate bearing capacity of single pile, reliability highest
Method, load transmission, pile side resistance, end resistance, pile shaft force, load one can be obtained by embedded testing element and settled
The parameters such as relation.The loading counterforce device of static load test can be divided into anchor pile beam according to the difference of field condition and pile body type
Counterforce device, ballasting platform counterforce device, anchoring pile ballast joint counterforce device, earth anchor counterforce device.
During construction project pile measurement, some test pile carries out test pile using umbellate form frame preloading mode,
Such a test pile mode is fetched earth using scene（Gather materials on the spot）So as to reduce urban road transport, reduce noise and environmental pollution etc.,
This kind of preloading mode generally uses at present.
A kind of static load resistance to compression lotus experimental rig of the prior art, as shown in figure 1, including support platform 1, being vertically fixed on
Column 19 and some pull bars 20 along the circle distribution of column 19 directly over support platform 1, the one end of pull bar 20 are solid with column 19
Determine the other end to fix with support platform 1, be provided with jack 2 immediately below support platform 1, the other end of jack 2 is arranged at test pile 3
Surface, examine and be additionally provided with datum line beam 5 by test pile 3, dial gauge 4 is provided with datum line beam 5, the other end of dial gauge 4 is with examining
Test pile 3 connects, and by being banketed in support platform 1, forms pressure to jack 2, then jack 2 is flexible to examining test pile 3
The pressure moved down is formed, and then the parameters such as the sedimentation for examining test pile 3 are shown by dial gauge 4.
It is in place of the deficiencies in the prior art, this preloading mode uses artificial meter reading（Dial gauge）Mode, be exactly often
Personnel are required to timing node and get into carry out artificial reading under support platform（Need to read >=97 by the pile of code requirement one
Reading, total time reading duration >=25h）；As test pile loading continues, the pressure that support platform is born incrementally increases, people's part work and part study
Table is more and more dangerous, and a load test pile pile quality is bad, and support platform collapses, and can cause personnel's death.
The content of the invention
