Description
Technical field
The utility model relates to a kind of pile tube, belongs to field of civil engineering, as the pattern foundation pit supporting structure, slope retaining, grouser basis etc. of civil engineering; Particularly a kind of pile tube be drawn out easily.
Background technology
Stake is the important primary structure member in civil engineering, and because its stress performance is good, easy construction, the application in modern civil engineering field widely.In traditional construction, stake is embedded in sub-surface, extracts very difficult, intactly extract just more difficult.But in modern Foundation Design and slope project, having a large amount of stakes to be that temporary lining is used, after engineering completes, needs are extracted.Conventional dismounting piling method adopts blasting technique to carry out destructiveness to remove, and wastes ample resources.A kind of pile tube being easy to extract of the utility model, in engineering, application can save ample resources, easy construction, plays a significant role in following civil engineering construction.
The current utility model about stake mainly increases the performance of stake by the section optimal of stake, as: CN102713077A discloses a kind of steel pipe pile, mainly solve the resistance reduced when stake is buried, patent CN102575446A discloses a kind of concrete filled steel tube compound pile, be the loading characteristic of performance according to different materials and stake, be optimized.
Along with the development of China's civil engineering, the pile foundation that increasing needs are removed or soldier pile are there is, also there is corresponding patented technology: as patent CN101173517 discloses a kind of pile-pulling construction method, steel bushing is squeezed into as casing in stake periphery, the shortcoming in force of this method is if run into underground obstacle, sleeve pipe cannot sink to, and the local pressure that cannula tip bears hammering is in addition crossed conference and caused casing deformation, and sleeve pipe is not easy to transfer to; Utilize full-rotating drill to extract the method (CN101629421) of deep pile foundation disclosed in Zhang Ruichang etc., abrasion drill pore-forming technique, according to illustration method, is implemented very difficult.A kind of intertidal zone beam lower carriage steel pipe pile of utility model patent CN203129146U utility model extracts equipment, and it utilizes hoist engine and truss and crossbeam etc. to carry out pile pulling, have certain feasibility, be also only limitted to Coastal Area.Above utility model all considers extracting of stake less than the structure design from stake self.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides one to extract conveniently, and the stake after extracting can re-use, the pile tube be drawn out easily economized on resources.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The pile tube be drawn out easily, comprises the tubulose stake of hollow and is filled in the filling tube core of tubulose stake inside, the sealed bottom shutoff of described tubulose stake; Described filling tube core can move axially in tubulose stake, and the tube wall of described tubulose stake is evenly provided with several perforates.
The material of described tubulose stake is steel pipe or steel concrete.
The diameter of described tubulose stake is less than 500mm.
Described perforate is that plum blossom-shaped is arranged.
The diameter of described perforate is 10-15mm, and perforate spacing is the 1/6-1/5 of tubulose stake diameter.
The diameter 3-5mm less of the diameter of tubulose stake of described filling tube core.
The material of described filling tube core is hard plastic tube.
The utility model adopts after said structure, and the tube pile structure of the application is simple, easy construction, has constructed easily to extract afterwards, and do not affect the rigidity of stake, intensity, the stake after extracting can reuse, and does not also affect the use of extracting rear place.Builing industry is the mainstay industry of China, and the making of pile foundation needs to consume a large amount of steel and cement, if stake can extract re-using, is both conducive to construction industry development, has and is beneficial to protection of the environment and economizes on resources.The utility model has good economic benefit and environmental benefit, significant to the sustainable development of builing industry.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of pile tube be drawn out easily, comprises the tubulose stake 1 of hollow and is filled in the filling tube core 2 of tubulose stake 1 inside, the sealed bottom shutoff of tubulose stake 1; Fill tube core 2 to move axially in tubulose stake 1.
As shown in Figure 2, the tube wall of tubulose stake 1 is evenly provided with several perforates 3.Perforate 3 is preferably arranged in plum blossom-shaped.The diameter of perforate 3 is preferably 10-15mm, and perforate 3 spacing is preferably the 1/6-1/5 of tubulose stake 1 diameter.
The material of above described tubular stake 1 is preferably steel pipe or steel concrete, and the diameter of tubulose stake 1 is less than 500mm and is advisable.
The diameter of above-mentioned filling tube core 2 is advisable than the little 3-5mm of the diameter of tubulose stake 1.The material of filling tube core 2 is preferably hard plastic tube.Fill the setting of tube core 2, when pile tube inserts in soil body process, the soil body outside tubulose stake 1 and water can be prevented, enter tubulose stake 1 inside by perforate 3, thus make follow-up high pressure ascending pipe be difficult to insert or do not have the effect of spraying water with high pressure.
A method for pulling out for the pile tube be drawn out easily, comprises the following steps:
The first step, extracts and fills tube core 2: extracted out by the filling tube core 2 being positioned at tubulose stake 1 inside.
Second step, injects pressure-air: high pressure water injection pipe is stretched into the first step and extracted tubulose stake 1 inside of filling tube core 2, start to inject pressure-air.Here high pressure water injection pipe, preferably shutoff bottom it, the sidewall of high pressure water injection pipe is provided with several perforates.
3rd step, destroy the soil structures outside tubulose stake 1: as shown in Figure 3, high pressure water injection tube edge rotates limit and is promoted to tubulose stake 1 top, and pressure-air is sprayed to the soil body 4 outside tubulose stake 1 by perforate 3, thus the soil structures outside tubulose stake 1 is destroyed, thus reduce pile extraction resistance;
4th step, tubulose stake 1 is cleared up, and reuses.Meanwhile, with the hole that earthen backfill tubulose stake 1 is extracted.
Tube pile structure of the present utility model is simple, easy construction, has constructed easily to extract afterwards, and do not affect the rigidity of stake, intensity, the stake after extracting can reuse, and does not also affect the use of extracting rear place.Builing industry is the mainstay industry of China, and the making of pile foundation needs to consume a large amount of steel and cement, if stake can extract re-using, is both conducive to construction industry development, has and is beneficial to protection of the environment and economizes on resources.The utility model has good economic benefit and environmental benefit, significant to the sustainable development of builing industry.
