The tubular pile comprises a prefabricated tubular pile, wherein the prefabricated tubular pile is pressed into a soil layer through hammering or static pressure and comprises a mother pile and a pile tip; a cavity extending from the pile tail to the pile tip is formed in the pile body of the mother pile; a layer or a plurality of layers of blade jacking holes communicated with the cavity are formed in the pile wall of the mother pile in the length direction of the pile body; blades which can rotate around rotating devices and rotate towards the direction far away from the cavity are arranged at the upper edge far away from the cavity of each blade jacking hole; and a force applying part used for jacking the blades out of the blade jacking holes is arranged in the cavity. The construction method of the prefabricated tubular pile can be referred in an instruction book; and compared with a conventional prefabricated pile, the pile body is provided with unfoldable blades, so that the end-bearing effect of the pile is greatly improved, the bearing capacity of the pile is increased by multiple times or even tens of times, the number of used piles and the pile length can be greatly reduced, and the comprehensive benefits are extremely remarkable.
Description
Technical field
The present invention relates to industry and residential construction area, especially relating to a kind of pile tube and construction method thereof with launching blade.
Background technology
Traditional precast concrete square pile with and pile tube, the bearing capacity of usual stake depends on the frictional force of a sidewall and the bottom bearing at pile top place.Due to the restriction of pile body and soil layer bearing capacity, when especially soil layer soil structure is poor, the bearing capacity of stake own is little.For meeting requirement for bearing capacity, usually can pass through increase the quantity of stake or add the length of timber pile self, very unreasonable economically.Further, because pile body is long in pile driving process, easily cause pile body breaking, pile body inclining, pile sinking does not reach designing requirement; Further, the restriction owing to transporting, time usual work is prefabricated, long stake is all segmentation prefabricating, after being transported to scene, needs spreading at pile driving process pile by merogenesis, causes a large amount of human and material resources costs; And pile body is spreading at the scene, quality affects by field condition, weather and the factor such as artificial, and pile extension place often has the phenomenon of the cracking that gets loose; The extensive mode of construction of tradition seriously hinders the construction of low-carbon (LC), harmonious society.
In sum, providing a kind of new preformed pile and construction, improve pile body structure feature simultaneously, in order to solve the drawback of traditional preformed pile, is the certainty of construction process development.
Summary of the invention
Object of the present invention is exactly to solve the problem, and provides a kind of pile tube and construction method thereof with launching blade.
For solving the problems of the technologies described above, embodiments of the present invention provide the pile tube that band launches blade, it comprises by the prefabricated tubulose stake in hammering or static pressure underground layer, prefabricated tubulose stake comprises female stake and pile top, the pile body of female stake has the cavity extending to pile top from stake tail, the pile lining of female stake is provided with along pile body length direction the blade that one deck or multilayer communicate with cavity and backs down hole, blade backs down that hole is provided with by tumbler away from the upper edge of cavity side can around this tumbler towards the blade rotated away from cavity direction, cavity is provided with force-applying piece blade top being backed down hole from blade.
Further, blade comprises:
Be installed on the intra vane that blade backs down hole, it has and extends and projection for coordinating with force-applying piece towards cavity;
Be installed on blade and back down the outer leafs of hole away from cavity side;
The top of intra vane, outer leafs side is in opposite directions connected to tumbler.
Further, protruding top adopts arc-shaped recliner face structure.
Further, blade along female stake pile body circumferentially.
Further, force-applying piece has the front end of circular arc.
Further, force-applying piece is steel pipe.
Further, blade back down hole in female stake symmetrically mode arrange.
Utilize band to launch the construction method of the pile tube of blade, it comprises:
Step one, preform carrier stake
Female stake is reserved internal cavities, meanwhile, the blade open holes of predetermined quantity is set along female stake pile body cross section and length direction pile lining;
Step 2, prefabricated and additional blades
According to predetermined reserved prefabricated blade, utilize tumbler to be attached to outside the blade open holes of female stake in the openable blade of customization, thus blade and female stake are connected as a single entity, and the non-closed condition of the original state of blade;
Step 3, female stake press-in soil layer
Under the state that female stake is closed at blade, by hammering or static pressure, squeeze in soil layer;
Step 4, opens blade
After female stake is pressed into designated depth, inserts the stake heart with force-applying piece, and by blade open holes, blade is backed down;
Step 5, mounted blade
After step 4 completes, continue female stake down hammering or static pressure, blade is backed down by its lower soil body completely along with the decline of pile body, finally forms the stake with the wing, whole prefabricated tubulose oil and pile body many places are held out against.
The present invention has following beneficial effect:
(1) on bearing capacity of pile, by being attached to one or more layers blade of female stake sidewall, participate in the middle of a self-bearing capacity, whole pile and soil body many places are held out against, compared with traditional concrete precast pile, several times even decades of times improve the supporting capacity of stake with Shangdi, and workmanship is improved simultaneously, safety significantly promotes, and comprehensive benefit is extremely remarkable.
(2) in preformed pile quantity and material, by improving, pile body supporting capacity is greatly improved, and for structure, available less preformed pile quantity, go to resist larger load, material usage greatly reduces, and meets low-carbon (LC) society.
(3) simultaneously, the minimizing of preformed pile quantity, greatly reduces the machine-team time of pile foundation equipment, and workman's site work amount greatly reduces, and labor cost is controlled further; .
(4) change traditional concrete precast pile force way and feature, give full play to the feature of each layer bearing capacity of the soil body, make pile body each several part stressed evenly with rationally, thus reduce female pile length further.
(4) band launches the tubulose pilework of blade, because supporting capacity improves further, thus make the long reduction of stake, single pile is carried and is become possibility, makes pile body under normal circumstances without the need to spreading, just can bear larger load, reduce site work amount, and reduce further by the impact of the factor such as weather, manpower, substantially reduce the construction period, economic benefit is very remarkable.
