Description

Edge of a wing friction pile

Technical field

The utility model relates to the stake of various basic loads such as a kind of construction work, bridge engineering, municipal engineering, hydraulic engineering, relates in particular to a kind of edge of a wing friction pile.

Background technology

The mankind are building bridge or building since ancient times, just use trunk to insert in the earth, the collateral resistance and the end resistance that utilize trunk and earth to produce, the bridge or the building on support trunk top, the timber that Here it is is still using now.

As everyone knows, so-called stake, be exactly the long column body of cross sectional dimensions much smaller than length, mainly show three aspects: the one, preformed pile, the material that uses is steel concrete, prestressed reinforced concrete and steel plate; The 2nd, bored concrete pile, the material of use are respectively concrete, steel concrete, sand, stone, lime soil, cement-soil and industrial residue etc.; The 3rd, the cross section figure develops into present rectangle stake and tubular stake etc. by original cylindrical stake.

At present, no matter the stake that use job sites such as construction work, bridge engineering, municipal engineering, hydraulic engineering is that preformed pile or castinplace pile are circular stake, tubular stake and rectangle stake mostly, along with the requirement of the development load fundation pile of construction market is also improving, especially present international and domestic building, all developing to high level, road and bridge are developing to large-scale, heavy, if the load of pile foundation needs to strengthen, generally be the load that the quantity taking to add the sectional area and the length of timber pile or increase stake improves pile foundation.The quantity that adds timber pile cross section and increase stake all can improve the cost of pile foundation, and the cost that has strengthened pile foundation then improves the cost of construction work.Stake types such as preformed pile, castinplace pile are arranged, in order to adapt to the soil condition of various complexity in the existing foundation pile construction technology.The stake type that has increases the end bearing capacity, but lost frictional resistance, extend in order the to increase frictional resistance length of pile body and enlarging section of the stake type that has is long-pending, thereby take a lot of work, take material, expend fund, expend problems such as the energy existing in varying degrees, particularly on the subgrade of complexity, owing to the poor stability of stake causes various bad sedimentations, bring in various degree difficulty for design and construction.

Summary of the invention

Main purpose of the present utility model is to solve the problem that the friction pile on various bases such as construction work, bridge engineering, municipal engineering, hydraulic engineerings exists, and provides that a kind of bearing capacity height, frictional resistance are big, the edge of a wing friction pile of good stability.

The technical scheme that its technical problem that solves the utility model adopts is:

Be made of pile cover, pile body and stake point, pile body is to be made of the pile core and the edge of a wing, along the relative parallel longitudinal of pile core several edges of a wing is set equidistantly and constitutes pile body.

The cross section of pile core is circle or polygon.The cross section of pile core is a hollow shape.

Cross section, the edge of a wing is trapezoidal, rectangle, polygon, circular arc, convexity, irregularly shaped.

The pile body upper end is provided with pile cover.The pile body bottom is provided with shoe and is connected.

Pile cover can be adopted in the upper end of pile body, and shoe can be adopted in the bottom of pile body.

Pile cover can be adopted in the upper end that is made of pile body the pile core and the edge of a wing, and shoe can be adopted in the bottom.

The utility model is an edge of a wing friction pile.The edge of a wing equidistantly is provided with along the relative parallel longitudinal of pile core, constitutes stable edge of a wing face, under the prerequisite that does not change pile length and section area, increases the superficial area of pile body itself and native frictional resistance significantly, has therefore increased the frictional resistance of stake.Increase about 30%-40% in the exterior surface area than existing stake under the identical situation of volume, the collateral resistance of stake improves 30%-40% than existing stake.The existing stake of total carrying force rate of calculating every single pile by overall target improves 22%-30%, and its cost of manufacture reduces 22-30%.

Characteristics of the present utility model are reasonable in design, and the frictional resistance of foundation pile and end bearing capacity are increased simultaneously, and pile foundation stability strengthens, material-saving, saving of labor, save time, energy-conservation, save investment.Applied range can be applicable to the reinforced concrete pile, preformed pile, castinplace pile, prestressed reinforced concrete stake on various bases such as construction work, bridge engineering, municipal engineering, hydraulic engineering etc.Meet People's Republic of China's industry standard " (technical code for building pile foundation " JGJ94-94.
