Abstract
The invention relates to a sand-filling hollow structure based cast-in-place special-shaped pile construction method. The method includes the following steps: (1) forming a pile hole according to a conventional pile-forming method, wherein the cross section of the pile hole is completely circular; (2) binding a special-shaped reinforcement cage framework; (3) lifting the special-shaped reinforcement cage framework into the pile hole, pouring concrete, and removing a structural binding face forming formwork after maintenance to form a reinforced concrete cast-in-place special-shaped pile. Materials are saved as the structural binding face is produced rather than the whole-circle section pile is adopted; the structural binding face can cling to the lining wall or outer walls of other main structures, so that use area of underground space is increased as compared with that of use of the whole-circle section pile; since contact area of the lining wall or the outer walls of the other main structures with the semicircular pile is large, effect of connection with a support pile is better; meanwhile a foundation of the lining wall or the outer walls of the other main structures is located on the underground cast-in-place pile with the lower section being completely circular, and structural behavior during operation is better.
Description
The application is number of patent application is 201310375478.8, and patent name irrigates applying of shaped pile for armored concrete

Technical field
The invention belongs to bored concrete pile field, especially a kind of perfusion abnormity pile construction method based on back-up sand hollow structure.
Background technology
Deposited reinforced concrete pile is a kind of directly pore-forming on the spot on stake position at the scene, then in the hole casting concrete or
Lay the stake of steel reinforcement cage casting concrete again, in construction project, it is cross-section for the deposited reinforced concrete pile of mechanical hole building
Face is a complete circle, although the bored concrete pile that transverse section is circular in underground engineering adverse construction method can meet supporting and want
Ask, but transverse section is that circular bored concrete pile wastes construction material in the case of equally meeting stress, transverse section is circular
Bored concrete pile can not be close to inwall or other agent structure outer walls occupy the usable floor area of a large amount of underground spaces.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of abnormity of the perfusion based on back-up sand hollow structure
Pile construction method, this construction method is simple, disclosure satisfy that saving construction material while underground engineering adverse construction method stress,
Reduce and take underground space utilization area, effectively reduce construction cost.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of perfusion abnormity pile construction method based on back-up sand hollow structure, its armored concrete perfusion shaped pile includes soil
The lower bored concrete pile of layer and the integrally formed agent structure in bored concrete pile upper end connection bored concrete pile, the connection filling of this agent structure under soil layer
The longitudinal direction of note stake makes structure binding face, and the step of the special-shaped pile construction method of armored concrete perfusion is as follows:
(1), it is first according to conventional pile making method and makes stake holes, stake holes transverse section is a complete circle；
(2), colligation deformed bar cage skeleton, this deformed bar cage skeleton includes filling pile cage of reinforcement under soil layer, agent structure
Connect filling pile cage of reinforcement and structure binding face forming panel；Under soil layer, filling pile cage of reinforcement enters for complete circle according to stake holes
Row routine colligation, after the completion of bored concrete pile part steel reinforcement cage colligation under soil layer, colligation agent structure connects bored concrete pile steel to one upwards
Muscle cage and structure binding face forming panel, the transverse section that this agent structure connects filling pile cage of reinforcement is semicircle or many semicircles
Shape is combined into a complete circle with the section of structure binding face forming panel, and deformed bar cage skeleton completes；
(3), lifting deformed bar cage skeleton enters in stake holes, casting concrete, dismounting structure binding face molding after maintenance
Template, forms armored concrete perfusion shaped pile.
And, the structure binding face forming panel that described armored concrete irrigates shaped pile is hollow structure, this hollow
Filling sand in structure.
And, under described soil layer, the cross section of bored concrete pile is circle.
And, it is laid with longitudinal reinforcement and transverse steel, longitudinal reinforcement edge in described agent structure connection bored concrete pile
Agent structure connects bored concrete pile outer and is uniformly arranged.
Advantages of the present invention and having the beneficial effect that
1st, the armored concrete perfusion shaped pile that this special-shaped pile construction method of perfusion based on back-up sand hollow structure is produced
Including bored concrete pile under soil layer and under soil layer the integrally formed agent structure in bored concrete pile upper end connect bored concrete pile, this agent structure
The longitudinal direction connecting bored concrete pile makes structure binding face, is laid with longitudinal reinforcement and horizontal steel in agent structure connection bored concrete pile
Muscle, longitudinal reinforcement connects bored concrete pile outer along agent structure and is uniformly arranged, and the present invention produces structure binding face ratio and adopts full circle
Section pile section about material；And structure binding face can be close to inwall or other agent structure outer walls, therefore ratio uses full circle
Section stake increases the usable floor area of the underground space, or while satisfaction definitely descends usable floor area, reduces to space outerpace
Occupancy；
2nd, the structure binding face forming panel that armored concrete irrigates shaped pile is filling in hollow structure, this hollow structure
Sand, effectively prevents deformed bar cage skeleton from integrally floating, and structure binding face forming panel also can be prevented to be deformed.
3rd, the armored concrete perfusion shaped pile that this is made based on special-shaped pile construction method of perfusion of back-up sand hollow structure by
Big with semicircle staking contacting surface in inwall or other agent structure outer walls, therefore can make it with support pile connection effect more preferably, with
When inwall or the basis of other agent structure outer walls be seated under the soil layer that lower section is full circle on bored concrete pile, work process
In stress performance more preferable；The present invention can adopt identical pore-forming equipment with ordinary skill stake in adverse construction method, is easy to apply
Work manages.
