The birth of the cast-in-place concrete thin-walled tube stake of major diameter technology is a major contribution to civil engineering, and domestic and international project circle has given high evaluation.When its contribution not only efficiently solves construction costs height in the large diameter pile foundation Foundation Design, long in time limit and technical bottleneck that difficulty of construction is big, have that job practices is simple, conspicuous superiority such as complete, the cast-in-place reliable in quality of fast, two steel pipe retaining wall of immersed tube time, excellent in durability and protection environment.Construction period shortens for 4 ~ June, for the investor comprehensively saves cost more than 20%.Can be widely used in the foundation treatment engineering, logistics goods yard engineering of the anti-ripple engineering of ocean engineering, hydraulic engineering, road and bridge engineering, harbour engineering, the engineering of reclaiming fields from the sea, harbour, upright bank protection work, railway engineering, airfield runway engineering, Industrial and Civil Engineering etc.
For further developing the superiority of the cast-in-place concrete thin-walled tube stake of major diameter technology, the inventor researches and develops and has proposed the invention of a kind of major diameter cast-in-place concrete thin-walled tooth-shaped tubular stake on the circular cylinder pile foundation, this invention diameter range is bigger, bearing capacity of single pile is higher, anti-horizontal thrust is bigger, it is stronger that anti-side sliding moves ability, tooth-shaped tubular stake for this structure of coordinative construction, need special-purpose profile of tooth stake point during its construction pile, be beneficial to quick pile, and preferably pile forming quality and improve efficiency of construction.
Summary of the invention
The utility model mainly solves the problems of the technologies described above, and has proposed the profile of tooth stake point of a kind of major diameter cast-in-place concrete thin-walled tooth-shaped tubular stake, and it cooperates two steel pipe casings, pile fast, and make pile quality reliable and stable.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the profile of tooth stake point of a kind of major diameter cast-in-place concrete thin-walled tooth-shaped tubular stake, comprise that the bottom is pointed annular body, described body diameter is that 800-2000 millimeter, internal diameter are the 600-1500 millimeter, its periphery is provided with several teeth, this teeth system is made of the outward extending projection of body, and it highly is the 150-1500 millimeter.During construction, the tooth-shaped tubular stake of the quantity of teeth and shape and desire pouring is suitable; The cast-in-place concrete thin-walled tube stake of major diameter technology is to adopt medium-high frequency vibrating hammer+two steel pipe casings+sharp structure of stake, the two steel pipe casings of major diameter are shaken to press to carve sink in the soil, in tube chamber, advance to move compacted at the bottom of making local foundation soil by shoe and part is discharged ground, when adopting the utility model pile, can in soil, form scallop and water the tooth-shaped tubular stake.
Based on the control balance and the purpose of controlling cost, as preferably, described teeth are provided with 2-12.2-12 teeth structure, the state that can be evenly distributed are laid in all sides of tube stake, both be easy to improve intensity, reach stress balance in formation of pile, also are beneficial to making.
As preferably, described teeth are 3 or 4, and sidewall directly is connected outside the adjacent teeth, and the outline that is constituted is rendered as triangle or square.This structure outline is rule comparatively, can make teeth bigger with the contact area of soil, also is beneficial to stack and taking up room when reducing to stack in enormous quantities, is beneficial to and deposits and transport.
In order to adapt to the needs of different construction environments, soil property and intensity, as preferably, the lateral margin of described teeth is straight line or curve or broken line.
As preferably, the top edge inboard of described teeth is provided with water stopping trough.The teeth end face of stake point is provided with water stopping trough, and the teeth of tooth-shaped tubular pawl can snap in the water stopping trough.Be convenient to alignment between the two, and sealing.
For further enhanced leaktightness effect, as preferably, described water stopping trough is to be distributed in the end face of teeth and body and the cannelure that head and the tail are communicated with.
Based on the purpose that is easy to make, as preferably, described teeth are casting or welding or assembled structure.
Teeth position convex, it is stressed bigger, in order to improve its supporting capacity of strength enhancing, as preferably, is provided with reinforcing bar in the described teeth.
Therefore, the utlity model has characteristics rational in infrastructure, that be easy to make, but especially coordinative construction tooth-shaped tubular stake, quick pile when being beneficial to the construction pile, and improve the forming quality of pile preferably and improve efficiency of construction; Its structural strength is big, sealing effectiveness is good.
