Description
Technical field
The present invention relates to building field, particularly a kind of Driven Piles stop hammering control method into shape.
Background technology
It is to reach supporting course certain depth as design requirement using pile top that hammering pile driving construction middle-end, which holds stake,.What is generally controlled stops hammer
In standard, it is desirable to which last three gusts of hammerings deflection control is no more than 5 centimetres (every gust 10 is hit) at every gust.In rock stratum, (stake supports power
Layer) distribution in erratic curve area, it is virtually impossible to survey the rock stratum absolute altitude of report to control the embedded depth of stake from ground, therefore
Also the reference for stopping hammer standard can not be used as according to stake embedded depth.
Be present more drawback in current various methods, controlled only with experience and pure range estimation, or stop hammer after hammering 10 times
Measure stake deflection.The former can cause a penetration control deviation excessive, as stake is not up to design supporting course, later stage superstructure
There is differential settlement risk；Hammering is excessive, not only lengthens the engineering time, further increases the risk burst after stake top excessively hammering.
The latter discontinuously hammers influence construction speed, and continuous hammering measurement then can influence workman dangerous in bottom operation.

Pile monkey stops Driven Piles when conjunction is required, otherwise pile monkey continues Driven Piles.Gauger can see in safe distance in measurement process
The deflection of stake is examined, a deflection, measurement process can more be accurately measured not with the relative position of graticule and scale mark
Need to stop hammer and gauger is in the measurement distance of safety.
In addition the application has further the advantage that compared with prior art：
1st, operate fairly simple, conveniently, safely；
2nd, hammer need not middle be stopped, it is ensured that the continuity as far as possible of hammering, because Driven Piles are whenever intermediate hold one
Hammered again after the section time, it is compacted because soil layer has gradually bounced back, the injection difficulty phase of both strike-ons after continuous and interruption
Difference is more, and strike-on is more difficult to be squeezed into.
3rd, this method is relatively more directly perceived and safe, and opposite end holds type Driven Piles and stops hammer standard control accuracy height, can more accurately control
Stake processed reaches the depth of design supporting course, does not owe to beat, and does not also surpass and beats.Reduce later stage superstructure differential settlement and crack in pile crown
Risk.
More than, only it is presently preferred embodiments of the present invention, any formal limitation not is made to the present invention, although this
Invention is disclosed above with preferred embodiment, but is not limited to the present invention, any those skilled in the art,
Do not depart from the range of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of change, as long as being that, without departing from technical solution of the present invention content, the technical spirit according to the present invention is real to more than
Any simple modification, equivalent variations and modification that example made are applied, in the range of still falling within technical solution of the present invention.
