Embodiment 1

[0052]Embodiment 1: A self-draining prefabricated pile, comprising: an inner pile body 1 and an outer casing 2; the inner pile body 1 is prefabricated reinforced concrete, and its shape is circular.

[0053] The outer casing 2 is divided into: a protruding part 2-1, a matching part 2-2, the matching part 2-2 is adapted to the shape of the inner pile body 1, and several vertically extending protrusions 2-1 are arranged on the outer casing 2 , the protrusion space 3 formed between the protrusion 2-1 of the outer casing 2 and the inner pile body 1 serves as a vertical drainage channel.

[0054] A number of permeable holes 2-2 are provided on the protrusion 2-1, so as to allow moisture to penetrate into the protrusion space 3 from the protrusion 2-1;

[0055] The matching part 2-2 is in contact with the inner pile body 1 .

[0056] The protrusions 2-1 of the outer case 2 are uniformly arranged.

[0057] A water suction pipe 4 is arranged in each raised space, and the water sucti...

Embodiment 2

[0072] Embodiment two: if Figure 6-7 As shown, the inner pile body 1 is rectangular, and the outline of the outer casing 2 is also rectangular. The outer casing 2 is divided into: a protrusion 2-1, a matching portion 2-2, and the matching portion 2-2 is connected with the inner pile body 1. The shape is adapted, and the outer shell 2 is provided with several vertically extending protrusions 2-1, and the protrusion space 3 formed between the protrusions 2-1 of the outer shell 2 and the inner pile body 1 serves as a vertical drainage channel; the protrusions 2-1 is provided with a number of permeable holes 2-2, so that water can penetrate into the protrusion space 3 from the protrusion 2-1; the matching part 2-2 is in contact with the inner pile 1; the protrusion 2-1 of the outer shell 2 Set multiples on each side of the rectangle;

[0073] The bottom of the internal pile body 1 is provided with a pile point 5, and the bottom of the internal pile body 1 is provided with an ann...

Abstract

The invention discloses a drainage type prefabricated pile which is convenient for construction and a construction method thereof. The shape of the inner pile body is adapted, and the outer casing is provided with several vertically extending protrusions, and the protrusion space formed between the protrusions of the outer casing and the inner pile body is used as a vertical drainage channel; the protrusions are provided with a number of permeable holes, In order to make the water infiltrate into the protrusion space from the protrusion; the lower part of the inner pile body is provided with a pile point, and the lower part of the inner pile body is provided with a ring-shaped protruding platform; The annular groove is provided with an obliquely rising spiral protrusion on the outside of the pile tip. The drainage type prefabricated pile and the construction method thereof, which are convenient for construction, can prevent the liquefaction of the soil around the pile under earthquake conditions, and are easy to construct.

Description

technical field [0001] The invention relates to the fields of rock and soil, construction, pile foundation and the like, in particular to a drainage type prefabricated pile which is convenient for construction and a construction method thereof. Background technique [0002] CN206655217U discloses a prefabricated concrete drainage pile, comprising a prefabricated permeable concrete pipe, the top of the prefabricated permeable concrete pipe is provided with an overflow tank, the bottom of the overflow tank is connected with a vertical drainage channel, and the drainage channel is connected with the outside world, and the prefabricated permeable concrete pipe The outside is covered with a concrete sleeve, and the bottom of the concrete sleeve is a slope. The prefabricated permeable concrete pipe is installed with a prefabricated concrete pile core. The bottom of the prefabricated concrete pile core is integrally formed with a conical core tip. The inner diameter of the core tip...
