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 is the construction method of steel concrete perfusion shaped pile, and the applying date is the divisional application of 2013.08.26.
Technical field
The invention belongs to castinplace pile field, especially a kind of perfusion shaped 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 concreting or lay the stake of reinforcing cage concreting again in hole, in construction project, its cross section of the deposited reinforced concrete pile of mechanical hole building is a complete circle, although cross section is that circular castinplace pile can meet supporting requirement when underground construction adverse construction method, but cross section is circular castinplace pile waste constructional materials when meeting stressed equally, cross section is the usable floor area that circular castinplace pile can not be close to that inwall or other agent structure outer walls occupy a large amount of underground space.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of perfusion shaped pile construction method based on back-up sand hollow structure is provided, this construction method is simple, can meet underground construction adverse construction method stressed while save constructional materials, 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 shaped pile construction method based on back-up sand hollow structure, its steel concrete perfusion shaped pile to comprise under soil layer castinplace pile and the integrated agent structure in castinplace pile upper end connects castinplace pile under soil layer, the longitudinal direction that this agent structure connects castinplace pile makes structure binding face, and the step of steel concrete perfusion shaped pile construction method is as follows:
, first conveniently piling method make stake holes, stake holes cross section is complete circle;
, colligation deformed bar cage skeleton, this deformed bar cage skeleton comprises filling pile cage of reinforcement under soil layer, agent structure connects filling pile cage of reinforcement and structure binding face forming panel; Under soil layer, filling pile cage of reinforcement is that complete circle carries out conventional colligation according to stake holes, under soil layer the colligation of castinplace pile part reinforcing cage complete after one upwards colligation agent structure connect filling pile cage of reinforcement and structure binding face forming panel, the cross section that this agent structure connects filling pile cage of reinforcement is that semicircle or most cross section that is circular and structure binding face forming panel are combined into a complete circle, and deformed bar cage skeleton completes;
(3), the lifting of deformed bar cage skeleton is entered in stake holes, concreting, dismounting structure binding face forming panel after maintenance, form steel concrete perfusion shaped pile.
And the structure binding face forming panel of described steel concrete perfusion shaped pile is hollow structure, fills sand in this hollow structure.
And the cross section of castinplace pile is circular under described soil layer.
And be laid with longitudinal reinforcement and transverse reinforcement in described agent structure connection castinplace pile, longitudinal reinforcement connects the uniform setting in castinplace pile outer along agent structure.
Advantage of the present invention and beneficial effect are:
1, this to comprise under soil layer castinplace pile based on the steel concrete perfusion shaped pile that the perfusion shaped pile construction method of back-up sand hollow structure is produced and the integrated agent structure in castinplace pile upper end connects castinplace pile under soil layer, the longitudinal direction that this agent structure connects castinplace pile makes structure binding face, longitudinal reinforcement and transverse reinforcement is laid with in agent structure connection castinplace pile, longitudinal reinforcement connects the uniform setting in castinplace pile outer along agent structure, and the present invention produces structure binding face and is about material than employing full circle section pile section; And structure binding face can be close to inwall or other agent structure outer walls, therefore than the usable floor area using the stake of full circle section to increase the underground space, or while meeting and descending usable floor area definitely, reduce taking space outerpace;
2, the structure binding face forming panel of steel concrete perfusion shaped pile is hollow structure, fills sand in this hollow structure, effectively prevents deformed bar cage skeleton entirety from floating, structure binding face forming panel also can be prevented to be extruded distortion.
3, this steel concrete perfusion shaped pile made based on the perfusion shaped pile construction method of back-up sand hollow structure due to inwall or other agent structure outer walls and semicircle stake contact surface large, therefore it can be made to be connected better effects if with soldier pile, the basis of inwall or other agent structure outer walls is seated lower section is simultaneously that under the soil layer of full circle on castinplace pile, the stress performance in the course of work is better; The present invention can adopt identical pore-forming equipment with common engineering pile when adverse construction method, and constructability manages.
