Abstract
Provided is a hydraulic lifting construction method for recycling a steel casing in pile foundation engineering. The method comprises the steps that the steel casing and a rotary pressed head are welded to form a closed high-pressure container, a high-pressure water pump is used for injecting high-pressure water into the container, a waterproof and seepage-proofing layer pile body is used as a supporting platform of counter-acting force (so that the loading action can be uniformly distributed), the steel casing is made to creep and ascend under the pressure action, the purposes that the steel casing can be removed without being damaged and can be recycled are achieved, pollution sources are eliminated, and resources are saved.
Description
Art
The present invention relates in foundation construction field, extensive use foundation piling technique, its steel pile casting be after pore-forming for resisting strata pressure, prevent the borehole wall from subsiding and concrete mould that foundation pile is shaping, after the sclerosis of foundation pile concrete, steel pile casting is just completely without having acted on, and corrosion ends.Steel pile casting harmless (not injuring pile foundation) can extract by the application of this technology, steel pile casting just energy Recycling, reach saving great deal of steel, steel pile casting is made to become circulation material by consumable material, stop to pollute because corrosion of metal produces body of groundwater, increase substantially the economic and social benefit of enterprise.
Background technology
At present, known foundation construction drilled pile steel pile casting is (main consider it is that the vibrations that produce in construction and huge mechanical external force are to the destruction of pile crown) that can not extract, overground part can only be extracted at most, under ground portion can only with the age increase progressively and corrosion gradually divided by soil and take off, this not only causes huge waste and causes long-term groundwater pollution.Abroad, in the construction of this field, use the mill stake machine of Japan, Germany's product, utilize the lifting force of 21 oil cylinders 600 tons to extract the locking of drilled pile steel pile casting, its shortcoming is that reaction force acts is on ground line, job site complexity is difficult to look for supporting surface, also easily causes pulling off and damaging of pile crown.So, at home in construction field, have no this form of construction work.
Summary of the invention
The technical scheme that the present invention solves its technical problem is: solder ball end socket on drilled pile steel pile casting, make it the pressure vessel of formation one sealing, fill airtight container after water, at injection water under high pressure, under the high pressure effect of water, its reaction force is with Uniform Loads on pile crown, steel pile casting is wriggled and rises, hang out with crane after reaching design height, realize the object of this technology.
The invention has the beneficial effects as follows, can in foundation construction field, harmless the extracting of steel pile casting becomes possibility, steel pile casting can be recycled, reach and save steel in a large number, increase substantially the economic benefit of construction enterprises, construct simple.
Below in conjunction with accompanying drawing and example, the present invention is further described.
Fig. 1. be that liquid act method steel pile casting pulls out schematic diagram.In the drawings, low-pressure water inlet tube 1, low-pressure water cuts down door 2., and water under high pressure cuts down Fig. 3., head formed by spinning 4., high pressure water injection pipe 5., steel pile casting 6., pile crown (pile foundation) 7., ground line 8..
Detailed description of the invention
In the drawings, head formed by spinning (4) is welded with steel pile casting (6), water is filled through low-pressure water inlet tube (1), close low-pressure water and cut down door (2), water under high pressure to be injected steel pile casting (6) and head formed by spinning (4) through high pressure water injection pipe (5) and is formed in the high-pressure bottle that seals by high-pressure hydraulic pump, carry out waterproof, impervious barrier pile crown (drilled pile) (7) as the support platform of reaction force, steel pile casting (6) is wriggled rising under pressure, reaches the object pulled out.
Claims (3)
1. a basic engineering construction engineering method, it is characterized in that: on steel pile casting, weld end socket, end socket is welded with high-low pressure water inlet pipe respectively, high-pressure intake pipe is connected with high-pressure hydraulic pump, it is characterized in that: steel pile casting and head formed by spinning form airtight high-pressure bottle, with high-pressure hydraulic pump, water under high pressure is injected in this container, using carry out waterproof, impervious barrier pile body as the support platform of reaction force, steel pile casting is wriggled rising under pressure, reach the object pulled out, must in Recycling, pollution abatement source, saving resource.
2. basic engineering construction facility according to claim 1, is characterized in that: steel pile casting and head formed by spinning form airtight high-pressure bottle on pile body.
3. basic engineering construction facility according to claim 1, is characterized in that: carry out waterproof, impervious barrier pile body as the support platform of reaction force.
