特許文献１には、先端側をテーパ状に形成した杭が開示されている。
特許文献２には、杭体外周面に袋体を巻着した杭材が開示されている。
特許文献３には、鋼管の先端部に羽根を設けた鋼管杭が開示されている。
Patent Document 1 discloses a pile having a tapered tip end side.
Patent Document 3 discloses a steel pipe pile in which blades are provided at the tip of the steel pipe.
上記特許文献１は、下記の課題を有する。
先端側がテーパ状に形成されているので、杭打ち時の抵抗が少なく、打ち込み易いと記載が有るが、打ち込む地盤によっては、打ち込みに大きな力が必要だったり、地盤に垂直に打ち込めないことがある。
The said patent document 1 has the following subject.
There is a description that the tip side is tapered, so there is little resistance when driving piles and it is easy to drive, but depending on the ground to be driven, a large force may be required or it may not be able to drive vertically to the ground .
上記特許文献２は、下記の課題を有する。
杭材を土中に設置する際（袋体に固化材を未注入）の圧入抵抗が小さいので、容易かつ正確に設置できると記載が有るが、中堀り工法等で杭材を設置するための竪穴を開けておく必要がある。
The said
There is a description that it can be installed easily and accurately because the press-fitting resistance is small when installing the pile material in the soil (no solidified material is injected into the bag). It is necessary to make a pit.
上記特許文献３は、下記の課題を有する。
鋼管杭を地盤に貫入する際、効率的に行えると記載があるが、羽根が穴径を大きくしてガタ付くので、貫入後、穴内部にコンクリートを充填する必要がある。
The said patent document 3 has the following subject.
Although it is described that it can be efficiently performed when the steel pipe pile is penetrated into the ground, it is necessary to fill the inside of the hole with concrete after penetration because the blades are loosened with a large hole diameter.
本考案の目的は、杭打ち時の抵抗が少なくて、地盤に打ち込み易いとともに、杭側面と地盤との間に働く周面摩擦力に優れた杭の提供にある。 An object of the present invention is to provide a pile that has low resistance during pile driving, is easy to drive into the ground, and is excellent in peripheral frictional force acting between the side surface of the pile and the ground.
（請求項１について）
杭は、先端部が先細のテーパー状に形成される円筒体と、この円柱体の先端部の外周に溶接される弦巻状のスパイラルとを備える。
円筒体は、先端の開口に円錐状の尖状体を嵌着し、後端の開口にキャップを固着している。
円柱体の先端部の外周に弦巻状のスパイラルを溶接している。
杭の先端を地表に当接して杭を回転させると、弦巻状のスパイラルにより、下向きの推進力が得られ、杭が地盤に貫入していく。
(About claim 1)
The pile includes a cylindrical body whose tip is formed in a tapered shape and a coiled spiral that is welded to the outer periphery of the tip of the column.
The cylindrical body has a conical pointed body fitted into the opening at the front end and a cap fixed to the opening at the rear end.
A chordal spiral is welded to the outer periphery of the tip of the cylindrical body.
When the pile is rotated with the tip of the pile in contact with the ground surface, a downward thrust is obtained by the spiral winding spiral, and the pile penetrates into the ground.
円筒体の先端部が先細のテーパー状に形成されているので、杭を地盤に貫入させる際の抵抗が少なく、杭を貫入させ易い。また、低騒音で、且つ低振動である。
円筒体の先端部以外は等径であるのと、弦巻状のスパイラルとにより、杭を地盤に貫入させた後は、杭側面と地盤との間に働く周面摩擦力が大きい。
Since the front-end | tip part of a cylindrical body is formed in the taper taper shape, there is little resistance at the time of penetrating a pile into the ground, and it is easy to penetrate a pile. Moreover, it is low noise and low vibration.
After the pile is penetrated into the ground due to the equal diameter except for the tip of the cylindrical body and the spiral wound spiral, the peripheral frictional force acting between the pile side surface and the ground is large.
杭は、円筒体の先端部の先端の開口に、円錐状の尖状体を設けている。
このため、杭を地盤に貫入させる際に、位置ズレや傾きを防止でき、杭が地盤に円滑に貫入していく。
The pile is provided with a conical pointed body at the opening at the tip of the tip of the cylindrical body.
For this reason, when penetrating the ground into the ground, it is possible to prevent displacement and inclination, and the pile smoothly penetrates into the ground.
杭は、中空の円筒体を採用しているので、強度低下を招くことなく、材料代や重量を低減できる。また、後端の開口にキャップを固着しているので、土砂や雨水が円筒体内に侵入しない。 Since the pile employs a hollow cylindrical body, the material cost and weight can be reduced without causing a decrease in strength. Further, since the cap is fixed to the opening at the rear end, earth and sand and rainwater do not enter the cylindrical body.
（請求項２について）
弦巻状のスパイラルは、断面が長方形であるので、杭を回転させると、下向きの大きな推進力が得られ、杭が地盤に円滑に貫入していく。
(About claim 2)
Since the cross section of the spiral spiral is rectangular, when the pile is rotated, a large downward thrust is obtained, and the pile penetrates smoothly into the ground.
本考案の実施例１（請求項１〜３に対応）にかかる杭Ａを図１に基づいて説明する。
杭Ａは、円筒体１の先端部１１の外周に弦巻状のスパイラル２を溶接し、溶接部分を含む表面には亜鉛メッキが施されている。
A pile A according to Example 1 (corresponding to claims 1 to 3) of the present invention will be described with reference to FIG.
The pile A welds a
円筒体１は、鋼で形成され、直径が約４３ｍｍ、長さが１．２５ｍである。なお、円筒体１の直径は２７ｍｍ〜６１ｍｍ、長さが６０ｃｍ〜４ｍの範囲が杭として好適である。 この円筒体１は、先端の約１／４の先端部１１が、スエージング加工により先細のテーパー状に形成され、先端部１１以外は等径とされている。 The cylindrical body 1 is made of steel and has a diameter of about 43 mm and a length of 1.25 m. In addition, the diameter of the cylindrical body 1 is 27 mm-61 mm, and the range whose length is 60 cm-4 m is suitable as a pile. The cylindrical body 1 has a distal end portion 11 that is about 1/4 of the distal end formed in a tapered shape by swaging, and has a constant diameter except for the distal end portion 11.
円筒体１は、先端部１１の先端開口に、円錐状の尖状体１２（ハガネ材）を固着している。また、円筒体１の後端開口には、鋼製のキャップが嵌着されている。
断面が長方形のスパイラル２は、鋼で形成され、先端部１１を包囲するテーパー状である。
In the cylindrical body 1, a conical pointed body 12 (steel material) is fixed to the distal end opening of the distal end portion 11. A steel cap is fitted into the rear end opening of the cylindrical body 1.
The
以下の様にして杭Ａを地盤に打ち込む。
杭Ａの後端を回転式杭打機に挟持させ、杭Ａの先端を地表に当接させた状態で、回転式杭打機を作動させ、杭Ａを回転させながら下方へ押圧する。
Drive pile A into the ground as follows.
With the rear end of the pile A held between the rotary pile driving machines, the rotary pile driving machine is operated in a state where the tip of the pile A is in contact with the ground surface, and the pile A is pressed downward while rotating.
弦巻状のスパイラル２により、下向きの推進力が杭Ａに加わり、杭Ａが地盤に貫入していく。
所定の深さまで杭Ａが地盤に貫入した時点で、回転式杭打機の作動を停止し、杭Ａから回転式杭打機を取り外す。
The downward spiral driving force is applied to the pile A by the
When the pile A penetrates into the ground to a predetermined depth, the operation of the rotary pile driver is stopped and the rotary pile driver is removed from the pile A.
杭Ａは、以下の利点を有する。
円筒体１の先端部１１が先細のテーパー状に形成されているので、杭Ａを地盤に貫入させる際の抵抗が少なく、杭Ａを地盤に貫入させ易い。また、回転式の杭打機を使用するので、低騒音で、且つ低振動である。
The pile A has the following advantages.
Since the front end portion 11 of the cylindrical body 1 is formed in a tapered shape, there is little resistance when the pile A is penetrated into the ground, and the pile A is easily penetrated into the ground. Moreover, since a rotary pile driver is used, it is low noise and low vibration.
円筒体１の先端部１１以外は等径であるのと、弦巻状のスパイラル２とにより、杭Ａを地盤に貫入させた後は、杭側面と地盤との間に働く周面摩擦力が大きい。このため、杭Ａが抜けたり、倒れたりし難い。 After the pile A is penetrated into the ground by the spiral winding 2 having the same diameter except for the tip 11 of the cylindrical body 1, the peripheral frictional force acting between the pile side surface and the ground is large. . For this reason, it is difficult for the pile A to come off or fall over.
杭Ａは、円筒体１の先端部１１の先端の開口に、円錐状の尖状体１２を設けている。このため、杭Ａを地盤に貫入させる際に、位置ズレや傾きを防止でき、杭Ａが地盤に円滑に貫入していく。
The pile A is provided with a conical
杭Ａは、中空の円筒体１を採用しているので、強度低下を招くことなく、材料代や重量を低減できる。また、後端の開口にキャップを固着しているので、土砂や雨水が円筒体内に侵入しない。 Since the pile A employs the hollow cylindrical body 1, the material cost and weight can be reduced without causing a decrease in strength. Further, since the cap is fixed to the opening at the rear end, earth and sand and rainwater do not enter the cylindrical body.
弦巻状のスパイラル２は、断面が長方形であるので、杭Ａを回転させると、下向きの大きな推進力が得られ、杭Ａが地盤に円滑に貫入していく。
Since the cross section of the
杭は、円筒体の先端部の外周に弦巻状のスパイラルを溶接しているので、回転式の杭打機で杭打ちする際の抵抗が少なく、地盤に打ち込み易い。また、杭Ａを地盤に貫入させた後は、杭側面と地盤との間に働く周面摩擦力を大きくできる。 Since the pile is welded with a spiral spiral on the outer periphery of the tip of the cylindrical body, there is little resistance when driving with a rotary pile driver and it is easy to drive into the ground. Moreover, after the pile A is penetrated into the ground, the circumferential frictional force acting between the pile side surface and the ground can be increased.
