摘要： The present invention relates to an end expansion type pile including a main body (100) in which a through hole is formed on a core part in a vertical direction and an expansion member, wherein the bottom surface gradually protrudes downwards from the edge to the center and a foreign substance discharge hole (201) is formed to be penetrated in the vertical direction, including a larger outer diameter than the outer diameter of the main body (100) and connected to the lower end of the main body (100). The present invention can be stably fixed on the bottom surface by excavating slimes.

摘要： 본 발명은 이음대상물을 구조적으로 안정되게 이음할 수 있는 커플러에 관한 것으로, 이음하고자 하는 이음대상물의 일측 단부가 삽입될 수 있는 연결공이 그 길이 방향을 따라 관통 형성된 관상의 연결부재와; 상기 연결부재의 연결공에 삽입되는 상기 이음대상물의 일측 단부 외주면에 체결되는 쐐기부재와; 상기 쐐기부재가 체결된 상기 이음대상물의 일측 단부 외주면에 상기 쐐기부재와 접촉되도록 삽입되어 상기 이음대상물을 상기 연결부재에 고정시키도록 상기 연결부재의 외주면에 체결되는 고정부재와; 상기 연결부재의 양측에 고정된 상기 이음대상물을 상기 고정부재 측으로 밀착시킬 수 있는 밀착수단을 포함하여 구성됨으로써, 이음대상물의 이음 부위에서 초기슬립이 발생됨을 억제하고 시간의 경과에 따라 접합 부위가 헐거워짐을 방지함과 동시에 접합 부위에 접합력이 동일하게 작용되도록 하여 이음대상물을 상호 균일하게 이음할 수 있는 효과가 있다.

摘要： PURPOSE: A pile with an extended head is provided to enable stable construction by preventing multiple extension members from touching the inner surface of a borehole. CONSTITUTION: A pile with an extended head comprises a pile body(100), an intermediate member(200), multiple extension members(300), a longitudinal guide unit(400), a center member(500), and an extension limitation unit(600). The pile body is buried in the ground. The intermediate member is coupled to the bottom end of the pile body. The extension members are extendible outward from the intermediate member in a radial direction. The longitudinal guide unit guides the radial extension of the extension members. When the center member touches the bottom surface of a borehole, the center member pushes the inner ends of the extension members outward. The extension limitation unit limits the extension of the extension members.
摘要翻译：目的：提供一种具有扩展头的桩，以通过防止多个延伸构件接触钻孔的内表面来实现稳定的构造。构成：具有扩展头的桩包括桩体（100），中间构件（200），多个延伸构件（300），纵向引导单元（400），中心构件（500）和延伸限制单元（600）。堆体被埋在地上。中间构件联接到桩体的底端。延伸部件从径向向中间部件向外延伸。纵向引导单元引导延伸构件的径向延伸。当中心构件接触钻孔的底面时，中心构件向外推动延伸构件的内端。扩展限制单元限制扩展成员的扩展。

摘要： PURPOSE: A bearing capacity reinforcement part and a pile with the same are provided to be used as a coupler when the piles are connected to each other and to reduce construction time and costs by reducing the amount of the piles. CONSTITUTION: A pile with a bearing capacity reinforcement part comprises a pile(100) and a bearing capacity reinforcement part(200). The pile is inserted into the ground. The bearing capacity reinforcement part is formed on the outer surface of the pile to increase the contact area with the ground and has a larger diameter than the pile to increase the bearing capacity of the pile.
摘要翻译：目的：提供一种承载能力加强部分和一个具有该桩的桩，以便当桩彼此连接时，用作联接器，并通过减少桩的数量来减少施工时间和成本。构成：具有承载能力加强部分的桩包括桩（100）和承载能力加强部（200）。将桩插入地面。承载能力增强部分形成在桩的外表面上，以增加与地面的接触面积，并且具有比桩大的直径以增加桩的承载能力。

摘要： PURPOSE: A front expanded pile is provided to secure the support force while maintaining the diameter of an existing through hole, and be constructed by preventing the contact of the through hole and an inner expanded member. CONSTITUTION: A front expanded pile comprises a pile body(100), an inclined portion(150), a plurality of guide members(200), and a plurality of expanded members. The pile body is formed to be buried on the ground. The inclined portion is formed in the lower portion of the pile body and the center portion of the inclined portion is projected more than edge portions. The guide members are installed in radial symmetry structure. The expanded members are installed to be projected outside.
