Abstract

The utility model discloses a pile tip structure for a prefabricated pipe pile. The pile tip structure comprises a pile tip, a pipe pile end plate and rib plates, wherein the pile tip is a triangular pyramid body by welding three side plates and a baseplate in an aligning manner; the pipe pile end plate is a ring-shaped round plate; the rib plates are in a shape of a long strip; the baseplate of the pile tip is located on the pipe pile end plate, and welded with the pipe pile end plate; the rib plates are distributed on the side plates, and welded with the side plates; one end heads, positioned on the pile tip baseplate, of the rib plates are welded with the pipe pile end plate. The pile tip structure is suitable for static pressure pile sinking construction of sand gravel soil layers, has the advantages of quick pile sinking speed and good pile sinking effect, and meanwhile has the advantages that the processing is easy, materials are saved, and the production cost is reduced, as compared with a cone-shaped steel pile tip.

Description

A kind of pile top structure of prefabricated tubular pile

Technical field

The utility model relates to the pile tube of building structural member technical field for foundation construction, especially a kind of pile top structure of prefabricated tubular pile.

Background technology

In the foundation construction of building construction, the application of prestressed pipe pile foundation is more and more extensive, when the piling construction of pile tube, conventionally adopt and impact pile sinking and two kinds of different forms of construction work of static pressure pile-sinking, for balancing pile bury end stress, to increase the penetration capacity of stake to soil layer, reduce broken pile probability, southern area tube pile construction adopts the construction technology of static pressure pile-sinking more at present.Meanwhile, adopt the technique of static pressure pile-sinking to have higher requirement to the pile top of pile tube, the pile top of prior art mainly contains cross-shaped steel pile top, open-type steel pile tip, tapered steel pile tip etc.; The problem existing is, because cross-shaped steel pile top and open-type steel pile tip run in the piling construction of sand gravel soil layer, all has the weak effect that buries, and causes static pressure pile-sinking effect not high, and the phenomenon that pile tube cannot be squeezed into even occurs; Tap web steel pile tip is because difficulty of processing is large, time-consuming, and material usage is large, causes cost of production to increase.

Utility model content

The purpose of this utility model is the pile top structure of a kind of prefabricated tubular pile of providing for the deficiencies in the prior art, the utility model is applicable to the static pressure pile-sinking construction of sand gravel soil layer, have advantages of that pile sinking speed is fast, pile sinking effect is high, meanwhile, there is easy processing, save material, reduce production costs than tap web steel pile tip again.

The concrete technical scheme that realizes the utility model object is:

A pile top structure for prefabricated tubular pile, its feature comprises pile top, pile end board and floor, and described pile top is by three blocks of leg-of-mutton side plates and a Rhizoma Sparganii cone that leg-of-mutton base plate is welded to dress, and pile end board is annular plectane, and floor is strip; The base plate of described pile top be seated on pile end board and with its welding, floor is three, floor be divided into the high along the line upper of triangle side plate and with its welding, and weld with pile end board the termination that floor is positioned at pile top base plate.

The utility model is applicable to the static pressure pile-sinking construction of sand gravel soil layer, has advantages of that pile sinking speed is fast, pile sinking effect is high, meanwhile, has advantages of easy processing, saves material, reduces production costs again than tap web steel pile tip.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A schematic cross-section of the utility model Fig. 1.

Detailed description of the invention

Consult Fig. 1, Fig. 2, the utility model comprises pile top 1, pile end board 2 and floor 3, and described pile top 1 is by three blocks of leg-of-mutton side plates 11 and a Rhizoma Sparganii cone that leg-of-mutton base plate 12 is welded to dress, and pile end board 2 is annular plectane, and floor 3 is strip; The base plate 12 of described pile top 1 be seated on pile end board 2 and with its welding, floor 3 is three, floor 3 be divided into the high along the line upper of triangle side plate 11 and with its welding, and a termination and pile end board 2 that floor 3 is positioned at pile top 1 base plate 12 weld.

The utility model is to use like this:

Making of the present utility model, by the drawing of pile top 1, with 16mm steel plate three blocks of leg-of-mutton side plates 11 of processing and a leg-of-mutton base plate 12, press the drawing of pile end board 2, with the pile end board 2 of an annular circle of 16mm steel plate processing, press the drawing of floor 3, with three floors 3 of 20mm steel plate processing; Three blocks of leg-of-mutton side plates 11 and a leg-of-mutton base plate 12 are connected into Rhizoma Sparganii cone to welding equipment, the base plate of pile top 1 12 is seated on pile end board 2, is adjusted with one heart and with its welding, again three floors 3 are positioned at respectively on triangle side plate 11 high along the line, and weld with side plate 11 respectively, and a termination and pile end board 2 that floor 3 is positioned at pile top 1 base plate 12 are welded, the utility model is made complete.

Construction of the present utility model, first locates the cone point of triangular pyramid in pile top 1 down and with pile foundation, then pile tube is vertically pressed on pile end board 2, can start pile driver and carry out pile sinking, and pile-sinking method is with conventional static pressure pile sinking construction method.
