Abstract
The replacement construction process of bored and cast-in-place piles features the replacement of bore slurry with mortar or concrete. The said cast-in-place piles include bored composite pile, bored expanded-base pile and bored composite expanded-base pile. The present invention can reduce the cost of cast-in-place piles while raising the bearing capacity of pile foundation.
Description
The present invention relates to pile foundation and the job practices and the construction equipment of building.
Bore slurry pressuring pile-forming can solve and easily collapse the hole and phreatic pore-forming pile problem is arranged, but owing to lack fines in the pile body, cause the folk prescription concrete cost of perfusion pile body more much higher than common filling pile, for addressing this problem, the present invention will solve with the replacement construction method of auger boring pouring pile and lack the fines problem in the concrete, thereby further reduce the cost of pile foundation, existing auger boring equipment can't carry out the construction of large-diameter deep stake.Therefore, its bearing capacity also is subjected to certain restriction, for further improving its bearing capacity, the present invention will be provided with vertically in the bottom of auger boring pouring pile body by stir with churning among at least a job practices gained mixture or enlarged body is set in the bottom of auger boring pouring pile body or enlarged body is set in the bottom of mixture, thereby constitute the pile series of auger boring pouring pile.
The objective of the invention is to propose pile series and the job practices and the construction equipment of auger boring pouring pile, so that reduce the concrete cost of pile body and improve the supporting capacity of stake.
The job practices of auger boring pouring pile of the present invention comprises replacement construction method and non-replacement construction method.
The replacement construction method of auger boring pouring pile: be bored into the precalculated position with auger stem, auger stem limit grout injection or stabilizing solution in auger boring are put forward in the limit then.When the cement paste of perfusion or stabilizing solution when reaching the precalculated position, auger stem can be proposed, in auger boring, place reinforcing cage, it is characterized in that when throwing in the auger boring has coarse aggregate, available cement mortar puts the cement paste drawn in the auger boring or when in the auger boring during non-coarse aggregate, available concrete is put and drawn auger boring interior cement paste or stabilizing solution.
But put among the cement mortar or concrete that the cement paste tripping of drawing out is used to replace, the stabilizing solution that is displaced can be stored among the special container, uses so that continue.
The cement mortar or the concrete that are used in the auger boring pouring pile replace are respectively progressively to distinguish replacing water mud or stabilizing solution from the boring end to top by cement mortar conduit or tremie.
The non-replacement construction method of auger boring pouring pile comprises the job practices of bore slurry pressuring pile-forming and the common auger boring pouring pile under nothing is collapsed the hole situation.
The pile series of auger boring pouring pile comprises auger boring composite pile, auger boring expanded bore pile and the compound expanded bore pile of auger boring.
The auger boring composite pile is in the bottom of auger boring pouring pile body mixture to be arranged vertically, and perfusion pile body and mixture fuse and constitute the auger boring composite pile jointly.
Mixture is by churning and the mixture that at least a job practices obtains among stirring.
The auger boring expanded bore pile is in the bottom of auger boring pouring pile body enlarged body to be arranged, and constitutes the auger boring expanded bore pile jointly by enlarged body and auger boring pouring pile body.
The compound expanded bore pile of auger boring is in the bottom of the mixture of auger boring composite pile enlarged body to be arranged, and constitutes the compound expanded bore pile of auger boring jointly by enlarged body, mixture and perfusion pile body.The pile series of auger boring pouring pile be by auger boring pouring pile body and the enlarged body that is provided with in the bottom of this perfusion pile body or with the mixture that is provided with along between centers, or with enlarged body that is provided with in this mixture bottom and the common formation of mixture.
Enlarged body comprises that mixing enlarged body, perfusion enlarged body and perfusion mixes enlarged body.
Mixing enlarged body is the enlarged body that obtains with the rotary-spraying construction method.
The perfusion enlarged body is to cut soil to inhale the expansion space that the slurry soil basketing method digs out with jet, pours into cementing material in this expansion space.
It is because the expansion space bottom of perfusion enlarged body has surface dust or sediment that perfusion mixes enlarged body, handles these surface dust or sediment with the churning method and it is formed mix enlarged body, and pour into cementing material in expansion space.
The job practices of auger boring composite pile is in the auger boring process or after boring is finished, can carry out the construction of mixture, among the mixture construction is carried out or after finishing, can carry out the construction of auger boring pouring pile body by the job practices of auger boring pouring pile.
The job practices of auger boring expanded bore pile is after auger boring is finished, can mix the construction of enlarged body or carry out the construction of expansion space or pour into and mix the expansion space among the enlarged body and mix the construction of enlarged body, when mix enlarged body or expansion space or perfusion mix among the enlarged body expansion space with mix after enlarged body finishes, can carry out the construction of auger boring pouring pile body by the job practices of auger boring pouring pile.
The job practices of the compound expanded bore pile of auger boring is in the auger boring process or after finishing, can carry out the drilling construction of mixture, after waiting to get into the mixture bottom, can carry out the construction of the enlarged body of mixture bottom, carry out the mixture construction then, can carry out the construction of auger boring pouring pile body by the job practices of auger boring bottling body in the mixture work progress or after finishing.
The job practices of auger boring pouring pile body is identical with the job practices of auger boring pouring pile.
The construction equipment of auger boring expanded bore pile is on the auger stem of existing auger boring equipment two medium channels to be set at least, if two medium channels, then one is fluidic channel, and another is for inhaling the slurry passage.
Churning comprises single tube, double pipe, triple pipe and multiple pipe.
Stirring comprises mixing-filling and stirring powder spraying.
