A kind of track sliding stake machine and job practices
Technical field
The present invention relates to the sliding stake of a kind of track machine and job practices, belong to ground and process king-pile machine engineering field, be particularly useful for drawing the hole and stake sets or the two class stakes foundation treatment engineering of construction etc. alternately.
Background technology
The stake machines such as present tube-sinking cast-in-situ pile, preformed pile, cement mixing pile, need on construction ground the steel pipe by its frame bottom, and the underlay sleeper is realized telephone-moving, because the not yet initial sets such as concrete, cement during telephone-moving, this telephone-moving mode easily makes the pile bodies such as the tube-sinking cast-in-situ pile that set, cement mixing pile broken pile occur, have a strong impact on its load-carrying properties, and because of the repeatedly telephone-moving of each position, so telephone-moving speed is slow, efficient is low.Adopt crawler-type mobile to improve a lot in telephone-moving speed, still have considerable influence setting pile center and stake Zhou Yidong to setting stake but crawler belt is also many, and each position also needs repeatedly telephone-moving more.
In the engineerings such as ground processing, pattern foundation pit supporting structure, be combined with more and more two classes or the above technique of two classes or stake type and obtained preferably economic benefit, such as the SMW engineering method, insert preformed pile, steel pipe pile, tube-sinking cast-in-situ pile in the cement mixing pile, the length stake that rigid pile and flexible pile are alternately arranged etc.; But each type need adopt corresponding equipment to construct respectively, needs mutual linking between the different construction equipments, and the telephone-moving of rear construction stake type construction equipment and set and can have a negative impact to construction stake, and speed of application is slow, work efficiency is low, construction cost is high.For example, cover at ground and to be mingled with the soil layer that thickness is large, bearing capacity is good in thicker crust layer or the ground, preformed pile is difficult to construction, often need draw first the hole, and then carry out the constructions such as preformed pile static pressure or hammering, need to draw hole equipment and press the sinking apparatus combination construction.
In sum, at present the stake facility such as tube-sinking cast-in-situ pile, preformed pile, cement mixing pile have translational speed slow, on setting the shortcomings such as the stake impact is large, human cost is high, and there is the blind area, visual angle in a machine operation personnel, and security incident easily occurs; The simultaneously alternately construction of kinds of processes and stake type have speed of application slow, need the shortcoming such as more personnel's cooperation.Need at present that a kind of telephone-moving speed of invention is fast, the stake impact is little, technique and stake type replace stake machine and the job practices that construction efficiency is high, human cost is low, working security is high more than 2 kinds on setting badly.
Summary of the invention
