摘要:
An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for water flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

A drainage system 10 comprises a hollow catchment chamber 14 having an elongate mouth 16 through which liquid enters the chamber 14, and a body 18 having first and second angled surfaces 20a and 20b that direct the flow of liquid collected in the chamber 14 to an outlet 22. Preferably the body is a triangular shaped body 18. The angled surfaces 20 direct the flow of water and other liquids in a linear course directly to the outlet 22, from where it is forced down a dropper pipe 24. This provides the catchment chamber 14 with an aggressive, self-cleaning capacity. The dropper pipe 24 is connected to the outlet 22 of the catchment chamber 14 for dropping the liquid collected in the chamber 14 directly into a carrier pipe 12.
摘要:
An athletic field is constructed using side-by-side conjoined layers of resilient synthetic material placed over a drain blanket and extending to a peripheral trench drain. The primary material construction is a rollable layer approximately 4 feet wide by 200 feet long comprising a dimpled polyethylene core material with bonded top and bottom thin, flexible geotechnic fabric layers. A flange and flap system along one edge receives the opposite edge of the joining strip to bond the laterally adjoining layers together in a shingling or tiered manner to promote drainage and to keep water out of the resilient pliable structure. The top surface is overlaid with artificial turf

A subsurface drainage assembly for directing fluid drainage from a surface is disclosed. The subsurface drainage assembly includes a plurality of drain structure panels linked together in a manner that permits movement of one drain structure panel relative to the adjacent drain structure panel. The drain structure panels have a laterally extensive backing grid and a plurality of spaced apart tubular support members projecting therefrom. The tubular support members are tapered so that the tubular support members are nestable with the tubular support members of an identical drain structure panel when the drain structure panels are stacked.

A soil stabilization and irrigation arrangement is proposed, comprising a useable area (10) and a water compensating device (22) disposed outside the useable area (10). The useable area (10) is formed from a basin (14) which is constructed as watertight and in which a drainage device (18) is arranged near the bottom, and which contains a footing (20); the water compensating device (22) is formed from a water receiving space (23) which is provided with a water inlet (24) and a water outlet (26) and which is in communication with the drainage device (18) of the useable area (10); and the useable area (10) further comprises an arrangement of soil stabilizing mats (32) in the footing (20) above the drainage device (18), wherein the soil stabilizing mats (32) are embodied as permeable to water.
摘要:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.

Improved golf course drainage systems (10) are provided which include respective drainage subsystems (12, 16), beneath the greens(14) and fairways (18) of a golf course, together with degassing apparatus (36, 64, 84) operably coupling the subsystems (12, 16) and permitting venting of contaminating gases generated within the drainage systems (10). The degassing apparatus (36, 64, 84) includes a tubular connector (44, 66, 85) establishing an offset distance between the adjacent ends (40, 42) of the subsystems (12, 16), along with a vent (46, 68) in communication with the connector (44, 66, 85). The connector (44) maybe upright to establish a vertical offset distance, or a generally horizontal connector (66, 85) may be used to establish a lateral or axial offset distance. The apparatus (36, 64, 84) permits normal drainage of water while preventing build up of undesirable gases which would otherwise rise through the soil and adversely affect the turf of the golf course.

A recreational surface such as an artificial turf playing field includes a pile fabric having a backing and a multiplicity of generally upstanding pile elements, and an infill overlying the backing and being interspersed between the upstanding pile elements. The infill advantageously includes resilient particles as well as particles of a rubber coated hard granular material such as rubber coated sand. The particles of rubber and the particles of rubber coated sand may be mixed together or they may be applied separately in different courses or layers in which the relative proportions of the two types of particles differ. Also disclosed is a method of designing and constructing such a recreational surface in which the properties of the recreational surface are specified according to the intended use of the recreational surface. For example, the impact resistance properties of the recreational surface may be engineered by adjusting the relative proportions of resilient particles and particles of rubber coated hard granular material.
