Description
Technical field
This utility model relates to a kind of industry and residential construction area, for the foundation engineering in architectural engineering, is specially a kind of base expanding and base expanding pile tube with launching blade。
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。How foundation engineering improves the bearing capacity of stake, reduces the length of stake, utilize soil body space, increasingly receive publicity。What is more, and bigger water buoyancy is often born in the 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。
In sum, 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。
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus providing a kind of base expanding and base expanding pile tube with launching blade。
Above-mentioned technical problem of the present utility model is addressed mainly by following technical proposals:
A kind of base expanding and base expanding pile tube with launching blade, comprise a female stake, cavity is left in described female stake, the bottom of described female stake is provided with blade, described blade is flexibly connected with female column bottom by connecting device, the bottom of described female stake is additionally provided with a top opening, and described top opening can open and close described blade。
As this utility model preferred embodiment, described top opening is power transmission leverage, both can press down, it is possible to pull-up。
As this utility model preferred embodiment, the described female elongated setting in pile length direction in cavity edge。
As this utility model preferred embodiment, described top opening is controlled by the core bar stretching into cavity。
As this utility model preferred embodiment, described female stake is concrete-pile。
As this utility model preferred embodiment, described female stake is circular, square or the prefabricated tubulose stake of polygon。
Base expanding and base expanding pile tube and pile-driving method thereof with launching blade of the present utility model has the following advantages compared to existing technology:
1, on bearing capacity of pile, the blade of an end it is placed in by connecting device, after opening, the concrete built downwards, form stake plug, the pile crown expanded, 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 stress, the stake plug effect formed bottom stake, make the stake of this construction technology in bearing capacity, pile both can have been made to be subject to uplift force, it is possible to so that pile is by downward pressure, in other words, namely uplift pile and compressive pile effect unite two into one；Without arranging the pile foundation of variety classes and character according to pressurized or tension；
3, 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 the requirement of low-carbon (LC) society；
4, the minimizing of prefabricated pile quantity, greatly reduces the machine-team time of pile foundation equipment, and workman's work on the spot amount greatly reduces, and labor cost is controlled further。
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。
