JPS6221925A - Burying of pile - Google Patents

Abstract

PURPOSE:To prevent the occurrence of noise in driving piles by a method in which a spiral excavating blade is attached to the tip of a pile having a pointed tip, and the pile is allowed to naturally penetrate and buried under ground by itself while being turned. CONSTITUTION:The tip of a pile 4 is shaped into a pointed form, and a spiral excavating blade 5 is attached to the pointed tip of the pile 4. The pile 4 is vertically supported by a rotary device 1 and turned by operating the device 1, whereupon the pile naturally penetrates into the ground by the action of the blade 5 and under the weight of pile 4. The pile 4 can thus be completely driven without the occurrence of noise.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for automatically penetrating into the ground with the pile itself while rotating the pile, which is provided with a spiral lifting blade or a spiral screw at least at the tip of the pile body formed into a pointed tip. This relates to the burying method, which is characterized by burying.

[Industrial application field]

Pile driving work in various civil engineering or construction works.

[Conventional technology]

Conventionally, pile burying work (during civil engineering or construction work) was mainly done by driving.

[Problem that the invention seeks to solve]

Due to the noise pollution caused by pouring work, various methods are being used.
Although devices were considered, it was not possible to completely prevent the noise as it was a concrete installation.

[Means to solve the problem]

We devised a method of naturally burying an antibody with a pointed tip by rotating a pile with spiral moat connecting blades near the tip.

[Effect]

By rotating the tip of the pile, the spiral moat blade, the pile's own weight, and the pile body, the antibody moves through the ground surface and is naturally buried.

〔Example〕

Further explaining this method, when the pile body 4 is rotated by attaching the tip 2f to the earth auger, drill piler, or other type of rotary device 1 and supporting it upright on the ground surface 3, a spiral blade or spiral provided at the tip This is a method in which the screws 5 and the pile bodies 4 have their own weight, and the piles naturally enter the ground one after another to complete the burial.

Therefore, the spiral blade or spiral screw 5 may be formed on the entire circumferential surface of the pile body 4, or may be provided only at the tip as shown in the figure, or may be provided with jumps or jumps at the tip, middle, or rear end. Any of the ones provided in the above may be used.

As mentioned above (the method of the present invention involves rotating a pile with a pointed tip and a spiral blade or helical screw 5 provided at least near the tip, and driving it into the ground as if screwing a screw nail into the ground. Since it is a screw-in burial method, it has the extremely remarkable effect of being able to be buried quietly and pollution-free without emitting almost any noise.
