Description
Technical field
The present invention relates to a kind of middle pick prestressed centrifugally pile tube (square) pile sinking device and novel pile sinking method thereof, be mainly used in the basis and the large equipment base of building, this method can make in same footpath and improve bearing capacity of single pile in the long scope equally.
Background technology
It is supporting the loading on building and various device basis prestressed centrifugally pile tube (side's stake), makes building, structure make De Genggao, so the diameter of the embedded depth of this stake and stake directly has influence on this bearing capacity.
The present most hammering stake method and the static pressed pile methods of adopting of pile-sinking method of prestressed centrifugally pile tube (side's stake) secondly are that the plunging that fetches earth also has the bored pile method.
1, hammering stake method: when the stake diameter is bigger, peripheral resident can adopt hammering method after a little while, and the hammering method noise is very big; Can produce a large amount of black smokes again during hammering, vibrate also very greatly, be a kind of pile-sinking method of high pollution; A lot of down towns ban use of, and the pile frame of present domestic maximum can only be hung 80 hammers simultaneously, and the impact force maximum also can only be 800T;, bearing capacity just can only change the bored pile method into when surpassing 800T, so present high ferro and bridge pile foundation are all selected bored pile construction for use.
2, static pressed pile method: the static pressed pile method is to utilize equipment self-weight to be pressed into a kind of method in the soil to stake; But because equipment self-weight is big; High to site requirements, it is also limited to be pressed into power, and the Static pressure pile driver of present domestic maximum is 800T; Bearing capacity of single pile surpasses 600T and just can't be pressed into stake, so the house also can only adopt bored pile more than 25 layers.
More than two kinds of pile-sinking method exist a kind of insurmountable problem; A large amount of stakes is beaten during (pressure) bury; The soil body is outwards expanded, and a large amount of building, road, subway, tunnel and pipelines etc. that squeeze soil influence periphery can both produce phenomenons such as crack, displacement; So in the down town and subway limit, tunnel are other and the building compact district all can not be beaten (pressures) and goes into prestressed centrifugally pile tube (side), also can only use the bored pile method instead.
3, boring extracting soil plunging: promptly bore a hole with borrow equipment in former ground earlier, be pressed into pile press to stake, this method can adopt at northern area; Because water content is less in the soil, the hole can form, but water content is higher in south and Yangtze River Delta Area soil; The hole can't form, and stake just can't be beaten (pressures) and gone into, in addition an also easy off normal; Secondly when stake is longer, boring extracting soil just more difficulty carry out, at present domestic borrow equipment the most deeply also can only arrive about 30 meters.
4, another kind of pile foundation is exactly the bored pile method, and this pile-sinking method is that a kind of nothing is squeezed native pile-sinking method, and the method is all used in the stake of some ultra dark super larges at present; The method is to utilize bath boring, and it is one clear that mud off carries out after the degree of depth, puts into the hole to prefabricated reinforcing cage then; Putting into cage to conduit again carries out two clear; Carry out concrete perfusion after reaching standard, bored pile has the cost height, long in time limit, quality is difficult to again control and in boring procedure, produce a large amount of mud, and mud is disposed and is difficult to; The job site is seriously polluted; A large amount of mud all dispose in the river, in the lake, in the sea, sewer and little creek be all blocked, government's annual cleaning sewer and creek mud expense are huge, simultaneously environment have been caused great pollution.
Summary of the invention
The deficiency of multiple pile-sinking method more than the present invention has overcome, can substitute does not have the bored pile method of squeezing soil fully, and bulilt-up area territory, subway limit, limit, tunnel all can sink big and dark prestressed centrifugally pile tube (square) in the urban centre.
The present invention is a kind of spirality fumarole on drilling rod and the drill bit that fetches earth that utilizes at prestressed centrifugally pile tube (side stake) center; The casting on one side of one edge injection is pile sinking on one side, after stake is sink to absolute altitude, just withdraws the position that the original place moves to second pile; Continue operation; Accomplish stake root high-pressure injection cement paste with a kind of high-pressure rotary-spray device in addition, form the stake of spheroidal napiform root, enlarge the bearing capacity of stake.
The present invention has realized the pile sinking device of a kind of middle pick prestressed centrifugally pile tube (side's stake); Comprise that walking (crawler type) main frame, hoist engine, unit head, hydraulic pressure draw anchor device, deposit native case, spirality drilling rod assembly; (1) is provided with guide rod (15) on walking (crawler type) main frame; Many groups pulley (11) that the top of described guide rod (15) is provided with is connected with unit head (2) with wire rope (8) through hoist engine (9); Unit head (2) lower end draws anchor device (3) to be connected with hydraulic pressure, and hydraulic jack (4) is fixed on hydraulic pressure and draws on the anchor device (3), and hydraulic jack (4) lower end is connecting deposits native case (5); Depositing native case (5) lower end is provided with pile cover (10) and prestressed centrifugally pile tube (side's stake) (6) and is connected; Deposit native case (5) behind and main frame (1) base and be provided with pulley (12), pulley (12) is connected with hoist engine (9) through pull-back cable (13), and unit head (2) center is connected with spirality drilling rod assembly (7); Spirality drilling rod assembly (7) passes to be deposited native case (5) and directly puts in prestressed centrifugally pile tube (side stake) (6) centre bore, and spirality drilling rod assembly (7) lower end drill bit is provided with a fumarole (14).
The invention provides the novel pile sinking method of a kind of middle pick prestressed centrifugally pile tube (side's stake), the steps include:
Shotcrete pipe is cleaned in step 13, water filling, and construction finishes.
The present invention has following remarkable advantages and beneficial effect:
1, has low cost, high benefit, low noise, friction, no mud, free of contamination advantage.
2, through casting limit, edge injection limit pile sinking, the jet soil property that can make fluffs, and hyperbar can enter soil smoothly again and deposit native case, ensures safety in production, and civilized construction is a kind of environmental protection worker method.
3, through edge injection digging on one side piling on one side, realized not having the soil of squeezing, guaranteed the ultra dark stake of heavy super large, filled up domestic blank in the urban compact area.
4, form the napiform root stake through the high-pressure injection cement paste at the root of stake, enlarged the bearing capacity of stake.
