The ring shape pre-tensioning pre-stressed concrete tapered pipe pile comprises a concrete pipe 3, while both end circumferences of the concrete pipe 3 are fixed with skirt boards 1, the both ends of the concrete pipe 3 are provided with end plates 5 fixed to the skirt boards 1, and the center wall of the concrete pipe 3 is provided with pre-stressed ribs 2 in axial direction along the circumference; the two ends of the pre-stressed ribs 2 insert the holes on the end plates 5, the pre-stressed ribs 2 are fixed with the end plates 5, the outer circumference of the pre-stressed ribs 2 are winded with spiral ribs 4, and the concrete pipe 3 is as a tapered structure 8. The product is used in the construction field.
Description
Technical field: the utility model relates to a kind of pre-tensioning system annular prestressed concrete conical pipe pile.
Background technology: China introduces prestressed concrete pipe pile so far surplus in the of existing 20 year from Japan from nineteen eighty-two, its specification of the pile tube of domestic production and use, size, arrangement of reinforcement and face shaping all are isometrical pile tubes, because aspects such as the penetration power of isometrical prestressed concrete pipe pile, bearing capacity, cost of production, economic benefit are not as conical pipe pile.And conical pipe pile is to be badly in need of product in the present building operations, does not up to the present also have conical pipe pile in the pile tube field.
Summary of the invention: the purpose of this utility model provides a kind ofly has stronger bearing capacity, penetration power, and the pre-tensioning system annular prestressed concrete conical pipe pile of convenient construction.
Above-mentioned purpose realizes by following technical scheme:
Pre-tensioning system annular prestressed concrete conical pipe pile, its composition comprises: concrete pipe, be fixed with skirtboard on the two ends circumference of described concrete pipe, the two ends of described concrete pipe are equipped with end plate and are fixed with described skirtboard, described concrete tube wall jackshaft is to along circumference presstressed reinforcing steel being housed, the two ends of described presstressed reinforcing steel is inserted in the plate hole of described termination and with described end plate and is fixed, be tied with spiral bar on the excircle of described presstressed reinforcing steel, described concrete pipe is a pyramidal structure.
Above-mentioned pre-tensioning system annular prestressed concrete conical pipe pile, the mid portion of described spiral bar are the non-encrypted section of reinforcing bar, and two ends are the reinforcing bar encrypted section.
Above-mentioned pre-tensioning system annular prestressed concrete conical pipe pile, the tapering of described concrete pipe and described spiral bar is 1: 75.
This technical scheme has following beneficial effect:
1. pre-tensioning system annular prestressed concrete conical pipe pile of the present utility model, be according to national GB13467-1999 Pretensioned spun concrete piles, building material industry JC888-2001 pretensioning prestressed concrete thin-wall pipe pile, the pertinent regulations of the GB4623-94 of country Circular prestressed concrete pole, production technology and technical requirements in conjunction with prestressed concrete pipe pile, that creates a kind ofly has more penetration power than unidimensional isometrical prestressed concrete pipe pile, bearing capacity, more convenient construction, the novel pile tube of more economical practicality.Φ in this project (325～190) * 55-10m conical pipe pile has begun to be extensive use of in the multistory building of Harbin, has obtained very good effect and economic benefit.
2. the big end of the conical pipe pile of this product has different design formulas respectively with the small end external diameter, and the design formulas of its small end external diameter is: d=D-L * K; The design formulas of big end external diameter is: D=d+L * K, wherein d is that small end external diameter, D are that pile tube length, K are pile tube tapering (1: 75) for big end external diameter, L, adopt above-mentioned formula no matter to calculate the small end external diameter and still calculate big end outside dimension, its result guarantees it is integer all the time, and calculates very convenient.
1., environment-friendly type 3. pretensioning prestressed concrete conical pipe pile of the present utility model has been compared ten big advantages with other form pile foundation:---pollution-free, noiselessness, no dust; 2., speed is fast---and a Φ (325～190) * 55-10m pile tube directly is pressed into underground and needs 15min; 3., the bearing capacity height---the tubular pile concrete strength grade is minimum to be C60, and bearing capacity of single pile is than high by 30% with other types of standard; 4., penetration power is strong---and large-tonnage static pressure machine can directly press fine sand layer to reach medium-sand seam Φ 600 diameter pile tubes; 5., intuitive is strong---and pile tube is prefabricated, and outward appearance comes into plain view; 6., checking conveniently---the procurator can detect at any time, and verification and measurement ratio reaches 100%; 7., static loading test is fast---promptly went out the result in 7 days with the load static pressure test; 8., can construct continuously---day and night, divide rain without hindrance; But 9. winter construction---frozen soil layer directly penetrates frozen soil with interior, static pressure machine Pile feeder at 50cm, more than the frozen soil layer 50cm, presses with the spiral drill hole earlier again; 10., cost is low---and in the various stake types that obtain with the tonnage bearing capacity, pile tube is most economical.
This product have simple in structure, craft science, intensity height, characteristics such as easy to use.
