Description

For determining the contraction locating support at pile foundation center

Technical field

This utility model relates to a kind of contraction locating support, is specifically related to a kind of for determining pile foundation center The contraction locating support of position.

Background technology

At present, at home in the pile foundation construction in construction site, the determination to drilling pile stake heart position, little Stake footpath pile foundation is different with timber pile footpath pile foundation.Wherein:

Paxilla footpath pile foundation mainly uses at stake mouth top layout flitch, on-the-spot to stake by total powerstation The setting-out of foundation pile heart position determines a heart design attitude, then carries out an outline by ribbon and arrives The range measurement of stake heart point position, judges the inclined of position according to the result of gained with stake footpath design load Move.This kind of method can judge pile foundation side-play amount with one-side.But this type of method shortcoming has: 1) Dangerous；During paxilla footpath pile foundation realizes stake heart design attitude setting-out, operator are at stake mouth Place carries out operation, and potential safety hazard is the biggest；2) professional stronger；Process to design stake position setting-out In, it is desirable to operator possess the relevant knowledge of surveying and locating；3) side-play amount drawn is one-sided , can not accurately obtain the actual position of drilling pile pore-forming；4) the side-play amount precision drawn is not Height, the result that this type of operation draws, deviation accumulation number of times is too many.

And timber pile footpath pile foundation arranges location gantry stake outside stake position and arranges ten before mainly using pore-forming Wordline, often saves with cross hairs centering, and ceiling hammer makees center control, to ensure stake position, after pore-forming I Check gantry stake, judge the skew of pile foundation position.But this type of method shortcoming has: 1) uneasy Entirely；Timber pile footpath pile foundation is laid cross hairs operator and is also at stake mouth operation, is unfavorable for safety work. 2) manpower is put into the biggest；Determine side-play amount by this type of method, at least want 3 operator's operations. 3) side-play amount drawn is inaccurate, the result that this type of operation draws, it is impossible to enough true reflection pile foundations are inclined Move and deviation accumulation number of times is too many；4) ease is the highest, and the pile foundation at non-disposable pore-forming is executed During work, cross hairs is laid and ceiling hammer, is required for professional and carries out；5) operation constantly Property strong, owing to cross hairs centering, ceiling hammer makees center control, to ensure constructing in stake position, Often construction one joint pile foundation, all can notify skilled addressee, carry out the control of stake position.

Utility model content
