Description
Technical field
The present invention relates to the building pile foundation construction machinery, particularly be furnished with the pressure of the drill formula pile press form of structure and the action principle and the construction technology of drilling equipment.
Background technology
Pile foundation is most widely used a kind of base form in the present Foundation Design, and it is divided into two types: preformed pile basis and bored concrete pile foundation.The job practices on preformed pile basis mainly contains: squeeze into two kinds of method, static pressure methods.The method of squeezing into is fit to all kinds of soil layers, the efficiency of construction height, and it is a kind of for many years traditional using method.This method is used greatly gradually less because of the big pollution of noise.Static pressure method is widely used in the construction of weak soil layer pile foundation, and the static pressure method piling has following advantage:
1, friction, noiseless, pollution-free in construction.
2, because stake is by the static pressure underground layer, stake is not subjected to the impact of the caused tensile stress wave of hammering, and reinforcing bar configuration and concrete intensity in the stake are all little than hammering stake, can save the engineering cost of stake.
3, the method pile sinking is squeezed in employing, and the peripheral soil of stake has " liquefaction " to a certain degree, and stake will just have real bearing capacity after after a while " rest "; Static pressed pile can not produce bigger interference to stake periphery soil in construction, the final pressure of pressure pile has embodied the actual carrying capacity of stake basically, after therefore construction is finished, can calculate the actual carrying capacity of stake rapidly according to the pressure curve of stake process of press in.
4, there is not broken pile substantially.
5, can directly carry out static loading test to stake with static pile press.
Though static pile press has above-mentioned advantage, still be only applicable to the weak soil layer construction of even matter at present, in sand layer and other hard soil layer, because pressure pile resistance is big, preformed pile often is difficult to pass smoothly this class soil layer and reaches projected depth.
Existing static pile press is divided into three major types by the action principle of its pressure pile, and promptly laterally the pressure static pile press is embraced in clamping, and roof pressure static pile press and many beams are embraced the pressure static pile press.The pressure static pile press is embraced in the horizontal clamping of the first kind, single armful and two kinds of forms of double embrace are arranged, and it is mainly formed and comprises the seat of drawing money on credit, main beam, supporting leg, clamping device guidance system, mobile piling support platform, operating system, center support base, last or/and following armful of piling beam, pile hoist crane, Weighting system, electrical system, hydraulic system.Embrace to press that silent piling has that speed is fast, good stability, go into the pile verticality advantages of higher, but because it adopts the mode of horizontal clamping stake to carry out piling, utilize the friction between anchor clamps and pile cutoff to transmit mechanical power, if the excessive easy bad pile cutoff of folder of clamping force, clamping force is too small to occur skidding again easily, thereby causes embracing the limitation of pressing static pile press to use.Along with constantly popularizing of static pile press, it is dominate gradually in building weak soil layer foundation construction field, thereby the demand of the concrete precast pile used of construction foundation working is increasing.Curing period is short, cost is low, the thin-walled pile for prestressed pipe of suitable large-scale production just constantly replaces precast square pile, the counterbore castinplace pile of other form, has become the main separation stake type of existing building weak soil layer foundation construction.To the construction of this class preformed pile, owing to embrace the inherent shortcoming of pressing static pile press, particularly require the bigger thin-walled pile for prestressed pipe of chucking power, can't construct sometimes even at all.The second class static pile press, one roof pressure static pile press arises at the historic moment, its walking support is basic identical with armful pressure static pile press, it is mainly formed and comprises the seat of drawing money on credit, main beam, supporting leg, center support base, roof pressure pile frame, jacked pile beam, jacked pile oil cylinder, such pile press is to carry out piling at the top of pile cutoff, and its piling power part piling oil cylinder places more than the pile cutoff top.It overcome armful press static pile press easily bad pile cutoff of folder, easily the defective of skidding takes place, but its structure is huge, speed of application is slow, safety is relatively poor, it is high to go into pile verticality.The 3rd class static pile press-many beams static pile press is the static pile press that the piling form that above-mentioned two classes are single is integrated, and it is that configuration top pile-pressing machine structure forms on the basis of single armful or double embrace static pile press.This machine mainly is made up of the seat of drawing money on credit, main beam, clamping device, guiding assemblage, mobile piling support platform, operating system, center support base, time piling beam or middle piling beam, Weighting system, electrical system, hydraulic system, last piling mechanism several sections.Though gentle armful a pressure static pile press and a roof pressure static pile press advantage separately, its piling mechanism complex structure, the Operation and Maintenance inconvenience of having closed of many beams static pile press.It has improved an armful defective of pressing static pile press easily to skid, easily press from both sides bad pile cutoff, but does not fundamentally overcome this defective.And its roof pressure power section still places more than the pile cutoff top, and its piling bearing reaction will pass to Piling machine traveller machine base by the roof pressure frame, causes pile frame center of gravity height, and inertia is big during walking, and whole structural stability is undesirable.Particularly owing to embrace the restriction in piling beam anchor clamps hole, pile cutoff is hung in also inconvenience of stake position, the installing/dismounting manufacturability is bad, and high-altitude upkeep operation amount is many, the hydraulic system structure complexity.Existing embracing pressed static pile press, roof pressure static pile press and many beams static pile press, and the function that provides static pressure to go into power all only is provided for they, the foundation construction of only suitable weak soil layer, and it is bigger to use limitation.Can not adapt to and wear sand layer or other hard soil layer construction, thereby need a kind of weak soil layer that can be suitable for of development be again the silent piling machinery that can be applicable to the hardpan construction.
