摘要:
A recoiling energy absorbing system is interpositioned between an outer shell that is exposed to percussive impact and a foundation. An energy absorbing layer with friction lugs is positioned inside the outer shell. The energy absorbing layer includes one or more energy absorbing modules with optional veins and drain holes. At least some of the modules are provided with one or more energy absorbing units that extend from an upper basal layer. At least some of the energy absorbing units are provided with a flexible wall that extends from the upper basal layer. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its undeflected configuration.

The present invention refers to a supporting element (310) for synthetic ground covers comprising a main body (311) having a corrugated shape with crests and valleys. The supporting element (310) comprises connecting means (330, 332), so that the connection of a supporting element with another supporting element allows to maintain the corrugated development of the main body (311). In addition, the present invention refers to a system comprising said supporting element.

The invention relates to a method for laying a playable surface (11; 21; 41; 51), comprising the steps of forming a relatively hard substrate (12; 22; 42; 52), arranging on the relatively hard substrate (12; 22; 42; 52) at least one layer of a resilient and/or damping material (13; 23; 43; 53), and arranging a top layer (14; 24; 44; 54) on the layer of resilient and/or damping material (13; 23; 43; 53). In one embodiment air chambers (27) are formed in the layer of resilient and/or damping material (23) during arranging thereof by including granules (31) having dimensions amounting to more than half the thickness of the layer (23). In another embodiment air chambers (17) are formed in the layer of resilient and/or damping material (13) by removing material therefrom at different locations after the arranging thereof. The invention further relates to a playable surface that is laid by applying this method.
摘要:
A method for building and renovating golf course sand bunkers to improve infiltration of water through a drainage system reduces the chance of contamination of the sand and to reduce erosion and maintenance and provide consistent playable sand for golf. The bunker is built to slopes based on the sand selected for use. A drainage system and a layer of fine pea gravel is installed over the entire floor of the bunker. A pre-polymer is sprayed onto the layer of pea gravel to secure it in place. The polymer sprayed bunker is permitted to cure for approximately 24 hours. A sufficient amount of bunker sand is added and compacted so the entire bunker is covered. Washed sod is placed around the bunker to stabilize the edge of the bunker.
