Description
Technical field
The present invention relates to a kind of method of on soft foundation, carrying out the punching pile driving construction, and the reinforcing cage of using in the method.
Background technology
The punching castinplace pile is to adopt the Churn drill pore-forming, and perfusion steel concrete forms in the hole then, is mainly used in pore-forming in the rock-soil layer.Adopt mud off during pore-forming, will after the bevel-type drill bit rises to certain altitude, come broken rock, draw the slag slurry of getting in the hole with positive and negative mud circulation then, transfer reinforcing cage and concreting pile after scarfing cinder meets the demands with the impact force of free-falling.Soft foundation is meant the geological environment that mainly is made up of mud, mucky soil or other high-compressibility soil layers.Mainly be distributed in fluvial facies, lake phase of wave, the marsh equal area in coastal littoral facies, delta facies, inland plain or mountain area.Have high-moisture, the high-voidage ratio, characteristic such as permeability is low, and compressibilty is high, and shear strength is low has characteristics such as significant thixotropy and creep properties.If on soft foundation, carry out being in the milk in percussion drilling, the hole, just be easy to hole, broken pile because concrete impact force and peripheral diffusion-induced stress cause collapsing.For fear of this situation occurring, generally adopt technical measures such as impact energy control, the control of pile monkey diameter, mud balance control at present.
Impact energy control is exactly that pointer adopts different block stamp strokes to different soil layers, reduces in the pore forming process the disturbance of soil layer on every side, and the phenomenon in the hole that prevents to collapse takes place, and reduces counter bore diameter; Select for use less than the pile monkey in design stake footpath (little by 50～80mm) usually when the control of pile monkey diameter is meant practice of construction; In the pore forming process in later stage; Become big because of the thixotropy of weak soil causes drilling diameter, make drilling diameter satisfy designing requirement, reach the purpose that reduces fullness coefficient; Mud balance control is meant the proportion of control slurry coat method, to different soil control mud balance, reduces the probability of happening of collapse hole, necking.But, more than three kinds of measures, all can not realize its effect well, poor control property, and cause site operation and design to disconnect.
Summary of the invention
The object of the invention; Be to provide a kind of method of on soft foundation, carrying out the cast of punching cast-in-place pile concrete; It can let actual stake hole conform to a design stake hole, and needn't adopt the not high technical measures of controllability such as impact energy control, the control of pile monkey diameter, mud balance control avoid collapsing hole, broken pile.
Another object of the present invention also is to provide a kind of reinforcing cage that is used to realize said soft foundation punching cast-in-place pile concrete pouring procedure.
The solution that the present invention solves its technical problem is:
Soft foundation punching cast-in-place pile concrete pouring procedure may further comprise the steps:
