A waterside leisure facility is disclosed which comprises an enclosure, covering and surrounding an area of land mass, an enclosed portion of a larger body of water, the land mass having a shore front adjoined to the portion of the body of water, the enclosure further comprising a dividing wall separating the enclosed portion of water from the remaining body of water a transparent roof, joined to the dividing wall and surrounding the area of land mass, to substantially separate air in the enclosure from ambient air outside the enclosure, while letting light through the roof, water treatment means arranged to maintain the water in the enclosure at a controlled temperature, while circulating water from outside the enclosure through the enclosure; and air conditioning means arranged to maintain the ambient air inside the enclosure at a controlled temperature and / or humidity.

An improved system is provided for preventing erosion of a bluff or hillside having a face extending between a toe at a bottom thereof and a crest at a top surface thereof, a water saturated zone extending rearwardly from the face, and a failure shear plane. The bluff or hillside is subject to excess water accumulation contributing to land mass degradation. The invention is improved by at least one drain member or wicking drain positioned behind the failure shear plane and extending downwardly and forwardly only along a single radius towards the face of the bluff and through the water saturated zone between the top surface of the bluff and the face of the bluff for the purpose of controlling drainage of the excess water accumulation. The drain member or wicking drain is installed from the top surface of the bluff or hillside so as not to impair the structural integrity and cause land mass degradation of the face thereof.

A sediment control roll includes a threshold member having large apertures therethrough, a hollow sediment collection chamber, and an outflow filter having small apertures therethrough. The sediment control roll can be used to collect sediment in runoff from a construction site, or to reduce removal of sediment from an existing land mass. The sediment control roll can for example be made by rolling up extruded polymeric netting with filter cloth attached thereto.

A method and system for delivering termite control material to selected portions of a land mass on which a structure is located are provided. Termite control material is delivered to selected portions of a land mass on which a structure is located, according to a predetermined zoned delivery plan that is based at least on the structure configuration, the entry areas at which entry of termites into the structure is most likely, and the hydraulic limitations of the fluid delivery conduit forming the delivery conduit system. Termite control material is delivered from the fluid delivery conduit system to selected delivery area(s) of the land mass through pressure compensating, root inhibiting emitters at predetermined locations in the fluid delivery conduit of the fluid delivery conduit system with verification of treatment through strategically placed moisture sensors. In one implementation of the principles of the present invention, the predetermined zoned delivery plan is designed to enable termite control material to be delivered to the land mass about the perimeter of the structure. In another implementation, the predetermined zoned delivery plan is designed to enable termite control material to be delivered to area(s) of the land mass that are proximate to locations at which entry of termites into the structure is most likely. In yet another implementation, the predetermined zoned delivery plan is designed to enable deliver termite control material to be delivered to the land mass below the entire foundation of the structure. Thus, the present invention provides a zone based control distribution system with verification of uniform, pesticide distribution.

The invention relates to a method for estimating exploitation and utilization actualities of underground spaces on basis of multiple urban geographic data. The method at least comprises the following steps of: obtaining a topographic map and a remote sensing map of an urban area and controlling drill hole information of each land mass; dividing meshes on the plane of the topographic map; arranging all the drilling hole information on a same reconnaissance controlling drill hole distribution map; projecting the arranged reconnaissance controlling drill hole distribution map to the topographic map; selecting whether to match the remote sensing map by combining the building type of a target land mass according to a drill hole quantity and drill hole depths, on the target land mass, of a reconnaissance controlling drill hole projection map, and determining an exploitation and utilization depth of an underground space; and calculating a resource quantity of the underground space according to the obtained exploited and utilized depth of the underground space. According to the method, the exploited and utilized depth of the underground space is distinguished by utilizing reconnaissance controlling drill holes, so that rapid and effective estimation is realized and the estimation result is high in correctness.

A disc type ditching and grass burying all-in-one machine comprises an universal transmission device, a suspension system, a rack, a gear transmission case, a ditching component, a grass burying mechanism and a earthing mechanism, wherein the suspension system adopts three-point rear suspension, and mainly comprises a suspension arm, a rear suspension arm and a suspension bracket support rod; and the ditching component mainly comprises a rotary blade, a main cutter head, wall cutting cutter heads, a wall cutting blade, a bearing and a bearing pedestal. The all-in-one machine can solve the problem that scattering of soil blocks into a gutter results in less ditching depth and affects grass burying quality; and the ditching depth is slightly greater than rotary cultivation depth, so that the purpose of cleaning a gutter bottom with a furrower is achieved, and the gutter bottom is leveled. The all-in-one machine adopts chain transmission for transfer, conveys the soil blocks at the right side part after ditching to above straws or into a furrow, and the purposes of straw turnover and a leveled land mass are achieved. The all-in-one machine can change the ditching depth, the ditching depth can be greater to improve the grass burying quality when the grass quantity is larger; and the ditching depth can be decreased to lower power consumption when the grass quantity is small.

A process reduces the insect, arthropod or pest content in land mass by providing molecular iodine in the land mass in a concentration in aqueous material in the land mass of at least 10 parts per million. The molecular iodine may be added in gaseous or liquid or solid state, and may be formed in situ in the land mass using available water in the reaction.

A process reduces the microbial content in land mass by providing molecular iodine in the land mass in a concentration in aqueous material in the land mass of at least 5 or 10 parts per million. The molecular iodine may be added in gaseous or liquid or solid state, and may be formed in situ using available water, added water and / or alcohol in the reaction.
