Description
Technical field
The present invention relates to technical field of building construction, particularly pile body verticality and the high Survey control method of stake top mark in a kind of silent piling work progress.
Background technology
Static pressure construction makes counter-force by static pile press with the counterweight on pile press deadweight and pile frame preformed pile to be pressed into a kind of process for sinking in soil.Construction of Static Pressure Pile technique low noise, friction, pollution-free, can 24 hours sequential production, shorten the construction period, create Saving in time costs, thus reduce construction costs; Because the contact surface of Pile feeder and engineering pile pile crown coincide better, Pile feeder can not roll and bob in pile follower process, thus can pile follower comparatively dark, the intercepting amount after foundation excavation is few; The stress caused due to piling in construction is less, and pile body there will not be tensile stress in work progress, and pile crown is generally all excellent, and multiple pressure is comparatively easy.Because static pressed pile has the advantages such as vibration is little, noise is low, mud-less pollution, bearing capacity of single pile are easily determined, be widely used in the engineerings such as shallow foundation, basement, equipment deep foundation, harbour.
But, because bearing capacity of foundation slab is uneven and influence on groundwater in static pressed pile piling process, make to strengthen the control difficulty of pile body verticality and absolute altitude during static pressed pile pile follower, satisfactory after correcting to be taked in time in pile follower process, therefore, measuring pile follower pile body verticality is exactly the most important thing.
Traditional pile body squareness measurement is after pile foundation is in place, make verticality by transit in the adjacent both sides of stake to observe, pile body perpendicular quadrature direction is arranged two hang stone roller vertical line carry out observations correction, pile driver still needs outfit one rectangular levelling rod, to measure the verticality of pile body at any time, and in piling process, control measure are not taked to pile body verticality, piling pile body deflection may be caused thus, and, pile head elevation control is when piling is close to pile body top mark height, uninterruptedly measured by survey crew, in control procedure, human factor impact is larger, the degree of accuracy is poor.
Summary of the invention
For in existing static pressure pipe pile pressing pile construction process, pile body verticality does not take control measure, easily cause pile body deflection, and pile head elevation control uninterruptedly need be measured by survey crew, human factor impact is large, the problem of poor accuracy, the object of this invention is to provide pile body verticality and the high control method of stake top mark in the construction of a kind of silent piling, the change of piling pile body verticality and the pile follower degree of depth can be observed intuitively and accurately, constructability technician takes counter-measure of rectifying a deviation in time, be conducive to on-the-spot construction control, thus improve piling pile body verticality and the high quality control of stake top mark, simplify measuring process, improve operating efficiency.
The present invention solves the high control method of pile body verticality and stake top mark in the silent piling construction that its technical problem adopts, and step is as follows:
