Abstract
The invention relates to a spike tooth concrete tubular pile for a building foundation and a construction method of the spike tooth concrete tubular pile. A plurality of square holes are formed in the pile body of a concrete tubular pile; spike teeth are plugged into the square holes before pile sinking; the sections of the spike teeth are square; an end cap is arranged at one end of each spike tooth; the end surface at the other end of the spike tooth is inclined; a steel pipe, of which the lower end is provided with a cone end socket, is placed in the concrete tubular pile after pile sinking; the spike teeth can be injected into a soil body by hammering the upper end of the steel pipe; and then concrete is poured into the concrete tubular pile. According to the invention, the spike teeth are placed in the pile body before pile sinking and are injected into the soil body after pile sinking, so that the friction force between the pile body and the geologic soil body on the condition that the pile sinking difficulty is not increased, that is, the bearing capacity of the pile is increased.
Description
One, technical field
The present invention relates to a kind of concrete tubular pile and job practices thereof, fourth tooth concrete tubular pile and job practices thereof that particularly a kind of building foundation is used.
Two, background technology:
Building foundation is as the concrete tubular pile of supporting usefulness; All using hammering, static pressure or vibration that concrete tubular pile is driven underground, do not go into the pipe stake, is to lean on the frictional force of pile tube wall and geology soil to support building as holding power; Improve stake and will improve the bearing capacity of stake with the native frictional force of geology; But the frictional force that improves stake and geology soil can or add the toothing bank do coarse of stake surface, so will make pile sinking difficult.
Three, summary of the invention:
The present invention overcomes above shortcoming, and a kind of fourth tooth concrete tubular pile and job practices thereof are provided.
The present invention realizes through following technical scheme:
A kind of fourth tooth concrete tubular pile and job practices thereof, the concrete tubular pile pile body is provided with several square holes, in square hole, fills in the fourth tooth before the pile sinking; Fourth tooth cross section is a square, and fourth tooth one end is provided with end cap, other end end slope; The steel pipe that behind the pile sinking lower end is had a cone termination is put into concrete tubular pile; The upper end of hammering steel pipe can be with in the fourth toothed portion injection soil body, and penetration concrete gets final product in concrete tubular pile thereafter.
The present invention has following characteristics:
The present invention inserts pile body with the fourth tooth before adopting pile sinking, again with the fourth toothed portion injection soil body, so, under the situation that does not increase the pile sinking difficulty, has increased the frictional force of pile body and geology soil behind the pile sinking, has promptly increased the bearing capacity of stake.
Four, description of drawings:
Below in conjunction with accompanying drawing the present invention is further described:
Accompanying drawing 1 is the sectional view of fourth tooth of the present invention in pile body.
Accompanying drawing 2 is the sectional view of part fourth tooth of the present invention outside pile body.
Among the figure: 1, steel pipe, 2, concrete tubular pile, 3, the cone termination, 4, the fourth tooth, 5, end cap, 6, the pile tube cap, 7, square hole.
Five, the specific embodiment:
Claims (1)
1. fourth tooth concrete tubular pile and job practices thereof, it is characterized in that: concrete tubular pile (1) pile body is provided with several square holes (7), in square hole, fills in fourth tooth (4) before the pile sinking; Fourth tooth cross section is a square; Fourth tooth one end is provided with end cap (5), other end end slope, and the steel pipe (1) that behind the pile sinking lower end is had cone termination (3) is put into concrete tubular pile; The upper end of hammering steel pipe; Can propose steel pipe with in the fourth toothed portion injection soil body, penetration concrete gets final product in concrete tubular pile.
