Abstract
The utility model relates to a hollow drainage prefabricated pile capable of largely increasing the bearing capacity of a single pile, which is composed of a pile body 1 and main rib racks 3 distributed on the inner edge of the pile body along the whole length of the pile body, and the main rib racks are wound and bound by hooping ribs 4. A steel reinforcement frame formed from the main rib racks and the hooping ribs is in a network shape, and the circumference of the steel reinforcement is concrete. The central line of the inner edge of the pile body is prefabricated into a hollow drainage passage 5 which penetrates through the whole pile body, and water seeping passages 2 are evenly distributed on the wall surface of the pile body at a certain distance along the direction of the length of the pile body. When the utility model is used, the bearing capacity of one single pile can be increased largely, materials can be saved, the bearing capacity of one single pile can be increased by 20% to 30% generally, the cost of prefabricated piles can be reduced by about 20%, the demand of building construction is satisfied, and the producing cost of prefabricated piles is reduced.
Description
Technical field: the utility model relates to the basic technology field in the civil works, particularly a kind of hollow draining preformed pile that can increase substantially bearing capacity of single pile.
Background technology: in containing all kinds of viscous foundation soil of pore water, when squeezing into or be pressed into preformed pile, hole in the foundation soil can sharply raise, thereby reduce pile side resistance and end resistance, especially in the soft foundation of the full water of big thickness, the intensive pile group of injection large tracts of land, not only bearing capacity of single pile reduces significantly, also may impact adjacent structure, underground utilities etc. simultaneously.
Summary of the invention: at the deficiency of above-mentioned prior art existence, the utility model provides a kind of hollow draining preformed pile that can increase substantially bearing capacity of single pile, preformed pile is made up of pile body and interior reinforcing bar thereof, be prefabricated into the hollow drainage channel that runs through whole pile body along center line in the pile body, water-permeable passage is arranged on pile lining at a certain distance; According to the requirement of building bearing capacity, different shapes such as described preformed pile cross-sectional structure can be square, circle, H shape, cross, triangle, described penetrating passage is circular, square, rectangle.
Adopt the utility model can increase substantially bearing capacity of single pile and save material usage, generally can improve bearing capacity of single pile 20～30%, reduce preformed pile cost about 20%, can satisfy the building operations requirement, reduced the preformed pile cost of production again.
Description of drawings:
Fig. 1 is the triangle preformed pile cross-sectional structure schematic diagram that provides according to the utility model.
Fig. 2 is the square preformed pile cross-sectional structure schematic diagram that provides according to the utility model.
Fig. 3 is the H shape preformed pile cross-sectional structure schematic diagram that provides according to the utility model.
Fig. 4 is the cross preformed pile cross-sectional structure schematic diagram that provides according to the utility model.
The specific embodiment: reach embodiment in conjunction with the accompanying drawings and describe, but protection domain of the present utility model is not limited to accompanying drawing and embodiment.
As shown in the figure, the various cross section hollow preformed pile structures that the utility model provides are made up of pile body 1 and interior main muscle frame 3 along the elongated layout of pile body thereof, twine binding by stirrup 4 between the main muscle frame, to increase the intensity of pile body; The cage of reinforcement that main muscle frame and stirrup constitute is network-like, is concrete on every side.Be prefabricated into the hollow drainage channel 5 that runs through whole pile body along center line in the pile body, along on the pile lining face of stake length direction, keep at a certain distance away and evenly arrange penetrating passage 2, they can be circular, square or rectangle.When preformed pile is squeezed into or is pressed into when underground, the pore water that sharply boosts in the foundation soil, just can infiltrate swimmingly in the cavity in the pile body, when water completely arrives the hole, can water be discharged ground with submersible pump, the pore water around the pile body in the ground can penetrate in the cavity of pile body again successively, near the water surface is elevated to ground, carry out draining again, arrange so repeatedly 3～4 times, the foundation soil around the pile body can tightly be embraced pile body.
Have a main muscle at least in each end of various profiled cross-section hollow preformed piles, main muscle is along the elongated layout of pile body; When bearing capacity strengthened, main muscle increased to two or many as required.
