Abstract
The invention discloses a concave-convex friction pile. A concave-convex structure is arranged on the outer surface of a pile body of the friction pile in the length direction of the pile body. The concave-convex structure is transverse or longitudinal. The concave-convex friction pile has the advantages that the concave-convex structure is particularly suitable for water stop of a port, a pier and a deep foundation pit, the frictional resistance of the pile is greatly increased through the concave-convex structure, the bearing capacity of the pile is increased, and the anti-floating effect and the anti-seismic effect are good.
Description
Technical field
The present invention relates to the realm of building construction, mainly refer to a kind of concavo-convex friction pile.
Background technology
Along with the fast development of offshore engineering, port works, existing prestressed concrete pile is because frictional force is limited, and the bearing capacity of single pile is lower simultaneously, is difficult to meet requirement of engineering.Therefore, construction cost is higher, needs a large amount of concrete and reinforcing bar, and economic benefit and environmental benefit all exist larger problem.
Summary of the invention
For solving the problems of the technologies described above, the invention provides following technical scheme:
A kind of concavo-convex friction pile, the pile body external surface of described friction pile is provided with concaveconvex structure along pile body, stake length direction; Described concaveconvex structure is horizontal or longitudinal.
In the present invention, described concaveconvex structure can be circular arc or semicircle or M shape.
In the present invention, described concaveconvex structure can be square or rectangle or trapezoidal or triangle.
In the present invention, the one side of described friction pile has concaveconvex structure simultaneously, and concaveconvex structure is interspersed.
In the present invention, described friction pile concaveconvex structure extremely can be zigzag.
In the present invention, the concaveconvex structure of described friction pile, thickness is 0.8-1.3 centimetre, is specifically as follows 1 centimetre.
In the present invention, the concaveconvex structure of described friction pile, depth of groove is 10mm-15mm, projection thickness is 15mm-25mm.
In the present invention, described friction pile is prestressing force, half prestressing force or non-prestressed, and the stake heart is solid pile or hollow pile, and cross section is square or rectangle or circle.
In the present invention, described concavo-convex friction pile also comprises pile top.
Adopt the technical scheme in the present invention, on the one hand, stake can be passed through soft layer, and pile top is propped up on the harder soil layer of carrying, and the load in stake carrys out balance by frictional resistance and end-resistance between stake perimeter surface and stake around; On the other hand, the technical scheme in the present invention, also plays anti-floating effect, especially in the structure such as dock, ship lock, underground storage tank, shallow embedding subway, arranges, and can effectively resist the huge buoyancy of underground water.In soil layer below storage tank is embedded in groundwater table time, as vacant in storage tank, loading reduces, buoyancy force of underground water can make storage tank floating, and the stake arranging under storage tank can utilize pile body frictional force opposing buoyancy.
In addition, concaveconvex structure also can play antihunt action.
The invention has the beneficial effects as follows: concaveconvex structure is specially adapted to port and pier and water seal for deep foundation pit, by concaveconvex structure, greatly strengthened the frictional resistance of stake, increase its supporting capacity, there is good anti-floating, anti seismic efficiency.
