Description
Technical field
What the present invention relates to is the building pile foundation construction equipment, particularly a kind of large-diameter ultra-deep static-pressure single tube immersing ramming grouting pile construction process and equipment.
Background technology
Building all needs firm ground, and its ground is made up of cushion cap and foundation pile.Foundation pile has a variety of, as cast-in-place concrete pile, concrete precast pile, steel pipe pile, steel sheet pile etc.The castinplace pile continuity is good, and frictional resistance is big, and single pile bearing capacity is strong, but must be first the pore-forming construction, after put reinforcing cage cast-in-situ concrete.Preformed pile can be produced by batch in factory earlier, at the scene with the method construction of beating, pressing, but its poor continuity, broken pile is many, and the pile extension place is unreliable, hidden danger is many, is unable to undergo corrosion saline and alkaline, seawater, and frictional resistance is less, defense sector pinking is poor.So still a large amount of cast-in-place concrete piles that adopt in important place.No matter which kind of foundation pile must reach bearing stratum just can have bigger single pile bearing capacity.But it is poor to run into the bearing stratum geological conditions, and as solution cavity, mud, quicksand, clay etc., single pile bearing capacity is difficult to reach designing requirement, particularly super-huge building and in the very dark area of coastal alluvial, and problem is more outstanding.Though can take the way of dilated diameter, the increasing degree of depth to improve single pile bearing capacity, increase cost and difficulty of construction greatly.People adopt the way that enlarges the stake bottom size to improve single pile bearing capacity in practice, have obtained good effect.Because the stake bottom size enlarges (also claiming ram-expanded pile), loaded area strengthens, so supporting capacity improves greatly.Under same single pile design supporting capacity condition, expanded bore pile is all littler than diameter, the length of expanded bore pile not, and bearing stratum only need select the geology of moderate strength can reach requirement, has saved cost greatly.
The ram-expanded pile job practices mainly contains at present:
A) wire rope pressurization (elongated weight hammering is auxiliary) single tube pore-forming is by directly interior compaction pile bottom, the descending reinforcing cage concrete perfusion again of ramming of elongated weight.This method is the most original job practices, its stake machine frame high immersed tube ability, generally can only construction depth less than 10 meters, diameter bottom-enlarging filling pile (utilization of complex carrier pile construction technology, urban construction archives, 2009 the 10th phase 53-54) less than 300mm.
B) the two-tube pore-forming of top hammering or vibration is extracted interior pipe, drops into fillers such as rubble, building waste, dryness concrete, and the indirect extruded and extended pile of pipe bottom hangs in reinforcing cage, the fluid concrete pile in hammering or the vibration.This job practices stake machine frame height, it is big that hammering shakes big noise, is unfavorable for environmental protection.Limited by height and capacity of equipment, this method can not construction diameter greater than 500mm, length bottom-enlarging filling pile greater than 20M.
C) the two-tube pore-forming of roof pressure is extracted interior pipe, drops into fillers such as rubble, building waste, dryness concrete, by the indirect extruded and extended pile of interior pipe bottom, descending reinforcing cage concrete perfusion pile again.It utilizes existing top pressing type hydraulic static pile pressing machine to finish.The hydraulic pulldown height is uphang the top at pile frame, because of the height and the hydraulic pulldown of pile frame can not be done big restriction, also can only construction depth less than 15 meters, diameter bottom-enlarging filling pile less than 400mm.(the compound bottom-enlarging filling pile of static pressure, immersed tube. construction technology, 2009,38 (9), 50---53).
D) Chinese patent ZL200610021640.6 discloses a kind of two-tube inner striking type construction method of immersed tube club-footed bored concrete pile, it is to make hammer in the pipe with elongated weight, the two-tube pore-forming of hammering in pipe, extract interior pipe, drop into fillers such as rubble, building waste, dryness concrete, again by the indirect extruded and extended pile in pipe bottom bottom, descending reinforcing cage concrete perfusion pile again in the hammering.This job practices stake machine frame height is only used hammer hidden pipe, and the immersed tube ability is not strong yet, this method can not construction diameter greater than 500mm, length bottom-enlarging filling pile greater than 20M.
Along with The development in society and economy, large-scale, super-huge building is set up one after another, and bottom-enlarging filling pile is strong because of its single pile bearing capacity, building costs is low, the geological condition adaptive capacity of bearing stratum is more and more come into one's own by force.Require the design and construction degree of depth greater than 20---40 rice, diameter bottom-enlarging filling pile, but such bottom-enlarging filling pile of constructing does not also have suitable construction equipment in the prior art greater than 500---1000mm.Chinese patent (200910273481.2) discloses a kind of interior steel pipe pore-creating filling pile construction technology and equipment of beating external pressure, and this technology has only been finished common tube-sinking cast-in-situ pile, can not finish bottom-enlarging filling pile.
