    • A pile coupling for prefabricated pile elements (1, 1') made of concrete, each comprising, at the end to be coupled, a cast-in metal sleeve (2, 2'), each sleeve (2, 2') being of a wavy design and having a length of at least one complete wave period (a). The wave form (3) at the location of the wave crest on the end face (4, 4') of the pile element (1, 1') is extended over a certain distance (x), such that when the end faces (4, 4') butt on each other, the distance between the wave troughs (14, 14') located on both sides of the joint face is greater than the wave period (a). Two half clamping rings (6), provided with a corresponding, regular wave profile (3) and having a length of at least two wave periods (a), are clamped around the metal sleeves (2, 2'), the arrangement being such that the end faces (4, 4') of the pile elements (1, 1') are pressed against each other with pretension.

    • For making a wall in the ground, a plurality of drilling pipes is drilled into the ground (7) next to each other and at a distance from each other, whereby these drilling pipes comprise a cylindrical tubular element (1) which is open at one extremity and carries teeth (2,3,4) and which is provided with at least one channel-shaped profile (5) which opens at the extremity of the tubular element (1) which is provided with teeth. By means of an injection pipe (8) provided in this profile (5), during drilling, a hardening liquid is injected into the ground uprooted by the teeth, whereby the drilling pipes are left in the ground (7) during the hardening of the mixture of ground and hardening liquid formed by the teeth.
    • 为了在地面上制作一个墙壁,将彼此相邻并且彼此间隔一定距离的多个钻孔钻入地面(7),由此这些钻管包括一个在一个开口处的开口的圆柱形管状元件(1) 并且带有齿(2,3,4),并且设置有至少一个通道形轮廓(5),该通道形轮廓在管状元件(1)的设有齿的末端处开口。 通过设置在该型材(5)中的注射管(8),在钻孔期间,将硬化液体注入到被齿根拔出的地面中,由此钻孔管在硬化期间留在地面(7)中 由牙齿形成的研磨和硬化液体的混合物。

    • The invention relates to a piling apparatus for driving a tube (1) closed at the lower end by a base plate into the ground (6) to form a concrete foundation pile. The apparatus comprises a piling hammer with falling weight (4) and an impact cap (3) acting on the tube (1). The tube (1), at the lower end thereof in the vicinity of the base plate (6), is provided with an inwardly thickened edge (2), while the piling hammer (3,4,5) is provided within the tube (1) and has an impact cap (3) resting in a centred position on both the thickened edge (2) and the bottom plate (6), said piling hammer (3,4,5) comprising a self-centring guide device (9,10,11) acting on the inner surface of the tube (1).
    • 本发明涉及一种打桩装置,用于驱动下端由底板封闭到地面(6)中的管(1),以形成混凝土基桩。 该装置包括一个重量减轻的打桩锤(4)和一个作用在管(1)上的冲击盖。 管(1)在其底板(6)附近的下端设置有向内加厚的边缘(2),而打桩锤(3,4,5)设置在管内( 1),并且具有在增厚边缘(2)和底板(6)上的中心位置处的冲击盖(3),所述打桩锤(3,4,5)包括自对中引导装置(9) ,10,11)作用在管(1)的内表面上。
