An underground access cover is provided. The underground access cover includes a substantially non-metallic base having a diameter. The underground access cover also includes a substantially non-metallic cap coupled to the base. The cap has a diameter that is longer than the diameter of the base such that the cap extends radially outward from the base to define a flange of the cover.

The invention relates to a vibrating device, kit and method for inserting a foundation element into the ground, wherein the vibrating device comprises:a clamping mechanism (18) for fixedly clamping the foundation element (12);a vibrator block (32) configured to provide a vibration for the purpose of inserting the foundation element (12) into the ground, wherein the vibrator block (32) is provided with resilient elements (6);a rotation mechanism operatively connected to the vibrator block (32) and configured to rotate the vibrator block (32) with the resilient elements (6), wherein the clamping mechanism (18) fixedly holds the foundation element (12); anda fixation mechanism (40) configured to apply a prestress to the resilient elements (6).

A coating film capable of being peeled off in the shape of sheet to facilitate a coating film removal work, and is less likely to peel even after long periods of use on an underwater structure is provided. The coating film comprises an undercoat layer to be bonded to an underwater structure, and an antifouling layer bonded to the undercoat layer, wherein: a 100-gram underwater constant load peeling degree of the coating film is less than 5; a ratio of a tensile breaking strength of the coating film to an adhesive force of the coating film with respect to the underwater structure, as measured after immersing the coating film in pure water at 60 C. for 5 weeks is 1.5 or more; and a 1-mm square cross-cut stretching-caused peeling degree of the antifouling layer with respect to the undercoat layer is 0.05 or less.

A system for assisting and improving the installation of playground equipment and related components, the system includes a life-size layout templates and a methodology for installation of foundations and other structures. The system tarp has holes at strategic locations which can be laid on the ground for marking the ground at each of the holes for foundations of the equipment and components of the equipment. For footing and foundation layouts, the required footings dimensions can be printed on life size/to scale tarps or fabric which can be laid out in the installation area and positioned to the exact needed use zone or placement of the site. After the position has been confirmed the footings can be cut to the appropriate footing size and excavated, giving a clean/dry work area and can be left to remain on the ground as a weed/vegetation barrier.
