Abstract
The invention relates to a lag pile for civil engineering foundations and a construction method for the lag pile. The middle of a thick pile is provided with a through hole; a thin pile is arranged in the through hole; the lower end of the thin pile is provided with a pile head; the pile head is a cone; and the diameter of the bottom face of the cone is greater than that of the through hole of the thick pile. When the lag pile works, firstly, the thick pile and the thin pile in the thick pile are sunk underground together; then, a steel tube is put at the upper end of the thin pile; a steel tube cap at the upper end of the steel tube is hammered to sink the thin pile; when the top end of the thin pile is in the thick pile for certain depth, i.e. when the thick pile and the thin pile are lapped for certain length, the steel tube is lifted, and a certain amount of concrete is filled in the through hole of the thick pile to perform fixation. According to the lag pile and the construction method thereof, a pile body can be sunk section by section, and when each section of sunk pile body is sunk, only the resistance between the pile body and a soil body needs to be overcome, and thus, pile sinking is easier.
Description
One, technical field
The present invention relates to a kind of lag pile and job practices thereof, the lag pile and the job practices thereof of particularly a kind of civil engineering basis usefulness.
Two, background technology:
During hammer piling, the frictional resistance of the pile body and the soil body increases along with the increase of the degree of depth, can't sink to owing to its huge frictional resistance makes stake during to a certain degree of depth.
Three, summary of the invention:
The invention provides a kind of lag pile and job practices thereof, the pile body segmentation is sunk to.
The present invention realizes through following technical scheme:
A kind of lag pile and job practices thereof are provided with a through hole in the middle of the thick stake, hole built-in one thin stake; Thin stake lower end is provided with a pile crown, and pile crown is a cone, and the diameter of cone bottom surface is greater than the diameter in thick stake hole; When the present invention works, at first will thick stake and thick stake in thin stake sink to undergroundly together, then steel pipe is inserted the upper end of thin stake; The steel pipe cap of hammering steel pipe upper end sinks to thin stake, thin stake top certain depth in thick stake; When promptly thick stake and thin stake overlap joint certain-length, propose steel pipe, a certain amount of concrete is fixing to get final product with pouring in the thick stake hole.
The present invention has following characteristics:
This lag pile and job practices thereof can make the pile body segmentation sink to, and every section pile body that sinks to only overcomes the frictional resistance of this section pile body and the soil body when sinking to, and pile sinking is easier to.
Four, description of drawings:
Below in conjunction with accompanying drawing the present invention is further described:
Accompanying drawing 1 is the structural representation of the thin stake of the present invention in thick stake.
Accompanying drawing 2 has gone out the structural representation of thick stake for the thin stake of the present invention.
Among the figure: 1, steel pipe cap, 2, steel pipe, 3, thick stake, 4, thin stake, 5, pile crown.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the present invention, is provided with a through hole in the middle of the thick stake 3 of this embodiment, hole built-in one thin stake 4, and thin stake 4 lower ends are provided with a pile crown 5; Pile crown 5 is a cone, and the diameter of cone bottom surface is greater than the diameter in thick stake hole, when the present invention works; At first will thick stake and thick stake in thin stake sink to undergroundly together, then steel pipe 2 is inserted the upper end of thin stake, the steel pipe cap 1 of hammering steel pipe upper end; Because this moment, thick stake was very little with the frictional resistance of thin stake, can very easily thin stake be sunk to thin stake top certain depth in thick stake; When promptly thick stake and thin stake overlap joint certain-length, propose steel pipe, a certain amount of concrete is fixing to get final product with pouring in the thick stake hole.
Claims (1)
1. lag pile and job practices thereof is characterized in that: be provided with a through hole in the middle of the thick stake (3), hole built-in one thin stake (4); Thin stake (4) lower end is provided with a pile crown (5), and pile crown (5) is a cone, and the diameter of cone bottom surface is greater than the diameter in thick stake hole; When the present invention works, at first will thick stake and thick stake in thin stake sink to undergroundly together, then steel pipe (2) is inserted the upper end of thin stake; The steel pipe cap (1) of hammering steel pipe upper end sinks to thin stake, thin stake top certain depth in thick stake; When promptly thick stake and thin stake overlap joint certain-length, propose steel pipe, a certain amount of concrete is fixing to get final product with pouring in the thick stake hole.
