Description
Technical field
The present invention relates to technical field of building construction, hang down particularly to pile body in a kind of static press piling work progress
Straight degree and the high measurement control method of stake top mark.
Background technology
Static pressure construction is to make counter-force by prefabricated by static pile press with the counterweight in pile press machine deadweight and pile frame
A kind of process for sinking in stake press-in soil.Construction of Static Pressure Pile technique low noise, friction, pollution-free, permissible
Construction continuously in 24 hours, shortens the completion time of project, creates Saving in time costs, thus reduce construction costs；Owing to sending
The contact surface of stake device and engineering pile pile crown coincide preferably, Pile feeder will not roll during pile follower and on
Under beat, thus can be relatively deep with pile follower, the intercepting amount after foundation excavation is few；Construction causes due to piling
Stress is less, and pile body does not haves tension in work progress, and pile crown is the most excellent, multiple pressure
It is relatively easy to.Owing to static pressed pile has, vibration is little, noise is low, mud-less pollution, bearing capacity of single pile easily determine
Etc. advantage, it is widely used in the engineerings such as shallow foundation, basement, equipment deep foundation, harbour.
But, during static pressed pile piling due to bearing capacity of foundation slab uneven and influence on groundwater so that
During static pressed pile pile follower, the control difficulty to pile body perpendicularity and absolute altitude strengthens, and to take in time during pile follower
Satisfactory after correcting, therefore, during measurement pile follower, pile body perpendicularity is exactly the most important thing.
Traditional pile body squareness measurement is after pile foundation is in place, is hung down in the adjacent both sides of stake by theodolite
Directly spend observation, set up in pile body perpendicular quadrature side two hang stone roller vertical line carry out observe correction, piling machine is still
A strip levelling rod need to be equipped with, to measure the perpendicularity of pile body at any time, and vertical to pile body during piling
Degree does not takes control measure, is thus likely to result in pile body deflection during piling, and, pile head elevation control
It is when piling is close to pile body top mark height, survey crew uninterruptedly measures, anthropic factor during controlling
Impact is relatively big, and accuracy is poor.
Summary of the invention
During existing static pressure pipe pile pressing pile construction, pile body perpendicularity does not takes control measure, Yi Zao
Becoming pile body deflection, and pile head elevation control uninterruptedly need to be measured by survey crew, anthropic factor impact is big,
The problem of poor accuracy, it is an object of the invention to provide pile body perpendicularity and stake top in a kind of static press piling construction
The control method of absolute altitude, it is possible to observe that the change of pile body perpendicularity and pile follower are deep during piling intuitively and accurately
Degree, it is simple to construction technical staff takes counter-measure of rectifying a deviation in time, is conducive to on-the-spot Construction control, thus
Improve the quality control that pile body perpendicularity and stake top mark during piling are high, simplify measuring process, improve
Work efficiency.
