モルタルｄの付着力とモルタルｄ自体の剪断抵抗によっ
て結合されている。[Prior Art] As shown in Fig. 3, the jacket pile a has an inner diameter that can surround the pile and form an appropriate gap with the outer periphery of the resistor when the pile is of a required thickness. Consists of jacket main pillar C,
The inner periphery of the jacket main column C and the opposing outer periphery are bonded by the adhesive force of the mortar d filled between them and the shear resistance of the mortar d itself.

相互に干渉して損傷を起す可能性かあり、また打設が困
難になる、などの問題がある。[Problems to be Solved by the Invention] However, when the load acting on the jacket main column C increases, the planar adhesion force of the mortar d alone cannot resist the load. Therefore, it is possible to install protrusions on the outer periphery of the pile and the inner periphery of the jacket main column C to resist large loads, but these protrusions may interfere with each other and cause damage when the pile is driven. There are problems such as corrosion and making pouring difficult.
本発明は、上述の実情に鑑み、ジャケット杭の耐荷性能

結合している。Figures 1 and 2 show an embodiment of the present invention, in which a protrusion (hereinafter referred to as Sharkey-1) is provided on the inner circumferential surface for increasing the mortar adhesion area and applying shear force acting on the adhesion surface. A structure 4 is manufactured on land by arranging the two provided jacket main columns 2 parallel to each other at a predetermined interval and passing a platform 3 across one end of the jacket main columns 2. The platform 3 is placed upright on a previously leveled seabed 5 with the platform 3 facing upward, and each of the jacket main pillars 2 has a required diameter slightly smaller than the inner diameter of the jacket main pillar 2, and the upper end is shaped into a funnel shape. The jacket main pillar 2 is inserted into the sleeve pipe 6 on the outer peripheral surface.
After inserting a pile 7 provided with a shank similar to the one provided on the inner peripheral surface and driving the pile 7 appropriately, the sleeve pipe 6 is pulled out, and then the inner periphery of the jacket main column 2 and the pile 7 are inserted. Mortar 8 is filled between the outer peripheries to connect the jacket main column 2 and the pile 7.
