Description
Technical field
The present invention relates to industry and residential construction area, especially relate to a kind of anti-pulling pipe piles with launching agnail, it is for the foundation engineering in architectural engineering。
Background technology
Since 21 century, along with the fast development of China's economic construction, the utilization of the underground space becomes new developing direction。Also it is subject to people's attention more and more。But in China's Coastal Areas, level of ground water is generally higher。Bigger water buoyancy is often born in underground structure in high water level soil layer, structures。For reducing the impact on hypogee of the water buoyancy, uplift pile basis generally need to be taked。Traditional precast concrete square pile and pile tube, the bearing capacity of usual stake depends on the frictional force of a sidewall。Due to the restriction of pile body Yu 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, it will usually by increasing the quantity of stake or adding the length of timber pile self, economically very unreasonable。Further, owing to pile body is long in pile driving process, it is easy to causing pile body breaking, pile body inclining, pile sinking does not reach designing requirement；Further, due to the restriction of transport, time usual work is prefabricated, long stake is all segmentation prefabricating, after transporting scene by merogenesis, needs spreading at pile driving process pile, causes substantial amounts of human and material resources cost；And, pile body is spreading at the scene, and quality is affected by field condition, weather and the factor such as artificial, and pile extension place often has the unclamped phenomenon split；The extensive mode of construction of tradition seriously hinders the construction of low-carbon (LC), harmonious society。
To sum up, it is provided that a kind of new prefabricated pile and construction, simultaneously improve pile body structure feature, in order to solve the drawback of traditional prefabricated pile, be the certainty of construction process development。
Summary of the invention
The purpose of the present invention is contemplated to solve the problems referred to above, it is provided that a kind of anti-pulling pipe piles with launching agnail。
For solving above-mentioned technical problem, embodiment of the present utility model provides a kind of anti-pulling pipe piles with launching agnail, it includes by the prefabricated tubulose stake in hammering or static pressure underground layer, prefabricated tubulose stake includes female stake and pile top, the pile body of female stake has the cavity extending to pile top from stake tail, the blade that the pile lining of female stake is provided with one layer along pile body length direction or multilamellar communicates with cavity backs down hole, blade is backed down the lower edge away from cavity side, the hole and is provided with the blade that can be directed away from the rotation of cavity direction around this tumbler by tumbler, cavity is provided with and blade is lifted off blade backs down the force-applying piece in hole。
Further, blade includes: is installed on blade and backs down the intra vane in hole, and it has the projection extended and for coordinating with force-applying piece towards cavity；It is installed on blade and backs down the hole outer leafs away from cavity side；The bottom of intra vane, outer leafs side in opposite directions is connected to tumbler。
Further, protruding top adopts arc-shaped recliner face structure。
Further, pile top is pyramid, and pyramid top is pile top end, and bottom is square, and the length of side of bottom is more than the length of side of female stake。
Further, blade is 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。
Utilizing the construction method of anti-pulling pipe piles with launching agnail, it comprises the steps:
Step one, preform carrier stake
Mother's stake being reserved internal cavities, meanwhile, arranges, with length direction pile lining, the blade that quantity is N along female pile body cross section and open hole, pile top is arranged to pyramid, and bottom pyramid, the length of side is sized larger than the length of side of female stake pile body, forms pile top agnail effect；
Step 2, prefabricated and additional blades
Prefabricated required blade, is installed on blade by prefabricated blade by tumbler and opens outside hole as required, so that blade is connected as a single entity with mother's stake, and has and can open turn over function, and the original state of blade is closed；
Step 3, female stake press-in soil layer
By mother's stake under blade closed mode, by hammering or static pressure, squeezing in soil layer, and squeeze in soil layer by mother's stake bending, now, the absolute altitude of female stake is less than default absolute altitude；
Step 4, opens blade
After female stake squeezes into the soil body completely, insert the stake heart with force-applying piece, and open hole by blade and blade is backed down；
Step 5, mounted blade
After step 4 completes, pulling out, pull out and return to designed elevation position on female stake is carried out, blade is opened by soil body extruding, forms blade agnail effect, thus producing powerful withdrawal resistance。
Compared with prior art, the present invention has following effectively effect:
(1) on bearing capacity of pile, by being attached to one or more layers blade of female stake sidewall, participate in come in the middle of a self-bearing capacity, whole pile and soil body many places are made to hold out against, compared with traditional concrete precast pile, several times even decades of times improves the bearing capacity of stake with Shangdi, and construction quality is improved simultaneously, safety is substantially improved, and comprehensive benefit is extremely notable；
(2) in prefabricated pile quantity with material, by improving, pile body bearing capacity is greatly improved, for structure, and available less prefabricated pile quantity, go to resist bigger load, material usage is greatly reduced, and meets low-carbon (LC) society；
(3) simultaneously, the minimizing of prefabricated pile quantity, greatly reduce the machine-team time of pile foundation equipment, workman's work on the spot 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 so that pile body each several part stress is evenly with rationally, thus reducing female pile length further；
(4) the resistance to plucking tubulose pilework with launching " agnail " blade, because bearing capacity improves further, so that the long reduction of stake, single pile load becomes possible to so that pile body, under normal circumstances without spreading, just can bear bigger load, reduce work on the spot amount, and the impact by the factor such as weather, manpower reduces further, substantially reduces the construction period, and economic benefit is very notable。
