Description
Technical field
Engineering pile foundation detection field is the utility model is related to, specially a kind of pile foundation displacement auxiliary detection device.
Background technology
Pile foundation displacement at pile top refers to that in pile driving process adjacent stake produces lateral displacement or stake rises.Main cause is
Stake number is more, and soil layer saturation is closely knit, stake spacing is smaller, and in pile sinking, soil is pressed against limit compactness and swelled upwards, adjacent stake
Be filled with together.Cause the situation of pile foundation displacement to have：When constructing, pore pressure is adjacent caused by pile sinking in weak soil
Stake is pushed side to or is filled with；Stake position unwrapping wire is forbidden, and deviation is excessive；Stake bit flag is lost in construction or extruding deviates, constructor
Member's arbitrarily positioning；Earthwork digging method and order are incorrect.The precautionary measures typically used in engineering have：Must not be same during pile sinking
When excavation pit, need to treat to be separated by reasonable time excavation after the completion of pile sinking, it is general suitable two weeks or so；Excavation of foundation pit must be led
Meaning drainage measure, indwelling side slope；Foundation ditch side must not stack the earthwork, and foundation ditch answers stage excavation more deeply；Pile foundation is carried out in digging process
Detect work.At present, common foundation pile displacement amount detecting device mainly has displacement rod-type detection means and displacement wire form detection dress
Put two types.During using displacement rod-type detection means, rigid rod is put at foundation pile displacement amount, rigid rod is extended into ground
Place, displacement transducer, the disposed outside pipeline of rigid rod are installed at the top of rigid rod.If the hole depth of foundation pile it is larger, it is necessary to
More rigid rod connections use, and due to the not reproducible use of rigid rod, it is high that displacement rod-type detection means has installation trouble, cost
Deng using shortcoming.Displacement wire form detection means includes comprising mechanical and two kinds of electrodynamic type, mechanical displacement wire form detection means again
Two steel wires, a wire connection card head, another steel wire are used to control dop to shrink or open, and two steel wires need to put simultaneously
In the hole for entering foundation pile.During measurement, easily winding leads to not control dop by steel wire two steel wires, and then causes to examine
Survey device integrally smoothly to take out from the hole of foundation pile, it is impossible to complete measurement task well.Electricity driving displacement wire form detection means is used
The electronic dop of cable connection, with the electronic dop of magnet control collapsed or opened, but existing electricity driving displacement wire form detection dress
Put and fixed pulley is fixed on datum line beam, the stress of cable and displacement can cause datum line beam to rock, displacement inspection when datum line beam rocks
Survey device also to rock therewith, so influence measurement result accuracy.
