Abstract

The utility model relates to a prestressed pipe pile comprising a tubular reinforced concrete pile body, characterized in that one end of the pipe pile is provided with a pile head prefabricated simultaneously with the pipe pile body, and a convex concrete rib is provided for every 2-7m on the pipe pile body with a width of 5-25cm and a height of 5-20cm. Comparing with prior art, the utility model has obvious advantages that the utility model can substantially improve bearing capacity of single pile under the same geological condition, reduce quantity of piles and project cost.

Description

A kind of pile for prestressed pipe

Technical field:

A kind of pile for prestressed pipe of utility model relates to the civil construction field, relates in particular to the building foundation field.

Background technology:

As everyone knows, in building foundation engineering, pile for prestressed pipe is low with cost, the duration is short, construction plant mud-less pollution and being widely used; But up to now, the top-down interior external diameter of the every in use root canal pile of pile for prestressed pipe both domestic and external, wall thickness all equate.

Summary of the invention:

The purpose of this utility model provides a kind of pile for prestressed pipe, can at equal geological conditions and same stake is long increases substantially bearing capacity of single pile down, thereby reduces a stake number, reduces construction costs.

The purpose of this utility model is achieved through the following technical solutions, a kind of pile for prestressed pipe is with technology is the same now, the tubulose pile body that all includes steel concrete, it is characterized in that: at pile tube stake end, the stake major part simultaneously prefabricated with tubular pile body arranged, at tubular pile body,, the wide 5-25cm of a protrusion, the concrete rib of high 5-25cm are arranged every 2-7m.

The utility model compared with prior art has following conspicuous advantage: it can increase substantially bearing capacity of single pile under the situation of same geology, reduce the stake number, reduces construction costs.

Description of drawings:

Fig. 1 is a generalized section of the present utility model.

(1) is the tube chamber of last pipe joint stake among the figure, (2) concrete rib ten for protruding, and (3) be the tube wall of pile tube, and (4) are the tube chamber of pipe joint stake down, and (5) are a major part of pile tube.

The specific embodiment:

An exemplary embodiments of the present utility model such as Fig. 1: produce every interval 2-7m by pile tube manufactory, pile tube with ribbing (2,3) and concrete pile major part (5) that the rib of the wide 5-25cm of a protrusion, high 5-20cm is arranged, treat that the two intensity reaches designing requirement, transport the job site to, stake major part (5) is placed on the stake position, pile tube with ribbing (2,3) is placed on the major part (5), with pile driver pile tube (2,3) is squeezed in the soil, promptly finish the making and the construction of this utility model, go round and begin again, finish the construction of all these required inventions.

Claims

1. a kind of pile for prestressed pipe of utility model includes the tubulose pile body of steel concrete, it is characterized in that:, the stake major part simultaneously prefabricated with tubular pile body arranged, at tubular pile body at pile tube stake end, every 2-7m, the wide 5-25cm of a protrusion, the concrete rib of high 5-20cm are arranged.
