Deployable curtains are fastened to the elongated side rails to further protect the electrical equipment rack from water damage.

The invention discloses a color emulsified asphalt and preparation method thereof, characterized in that color bituminous cements, emulsifier, water and modifying SBR rubber latex are included. According to proportioning by weight, parts of components are: 50.0 to 75.0 of color bituminous cements, 0.5 to 3.0 of emulsifier, 1.0 to 10.0 of modifying SBR rubber latex; 20 to 40 of water. The component and weight percent of the color bituminous cements comprise 30% to 65% of petropols, 1% to 3% of N,N'ethylidene bioleoylamido; lubricant or extract oil residual of lubricant. By selection of bituminous cements, in particular small amount of N,N'ethylidene bioleoylamido and SBR rubber latex, compared with other bituminous cements formulation, the formulation has better adhesiveness, which can prevent damages such as water damage, loose and peeling off of color path surface paved as well as tracks.

A dive accessory has an outer shell that encompasses a light maker and a noise maker. The light maker is waterproofed and has a light source electrically connected to an electrical power source for powering the light source. A light switch selectively opens and closes the electrical connection to switch the light source on and off. The noise maker has a hollow chamber containing a solid object that is movable within the hollow chamber to produce a noise when the solid object strikes a wall of the hollow chamber. The solid object may be restrained from moving to prevent the solid object from making noise. Combining a light maker and a noise maker provides a more effective dive accessory.

An air conditioning drain cleaning system with an automated blow-out cycle to clean out an evaporator pan drain pipe. The system has a pneumatic valve assembly, a controller, a float level switch assembly and a plurality of air lines in a manifold for actuating the pneumatic valve assembly and blowing out the drain pipe. The controller directs the system to initiate or repeat a blow-out cycle until the drain pipe is clear. The pneumatic valve assembly bisects the drain pipe to selectively close the pipe for cleaning with a pair of high pressure air shots, one shot toward each pipe end to dislodge a clog. The float level switch assembly signals the controller if the condensate level in the drain pan drops. If the condensate level does not drop, the controller initiates a further blow-out cycle at increased pressures until the line is clear.

The invention relates to a novel water control method suitable for mine shafts, which is characterized by firstly adopting grouting for water plugging at a water-bearing layer at the upper part of the shaft; arranging a wall seat at the boundary of the water-bearing layer and a water-resisting layer and arranging a bypass for water interception after the wall on the upper surface of the wall seat; arranging a dewatering orifice in the bypass and arranging a water guide pipe in the orifice, wherein the wall seat is wider than the bypass and the wide part of the wall seat is upwarped for water blocking; arranging a water collecting ring in the shaft at the upper part of an access road and draining water collected by the water collecting ring into the bypass after the wall, wherein a baseplate of the access road is 200-300mm higher than the bypass; and pre-burying a drainage pipe and enabling gushing water collected at the upper part of the bypass to self-flow into a water sump and be further drained to the ground through a drainage device. By adopting the novel water control method, the construction conditions of the mine shaft can be improved, the construction quality can be improved and the progress can be accelerated; furthermore, water damages can be effectively prevented during the production period of a mine, the safety of the mine shaft is protected, the drainage cost is reduced and the service life of the mine shaft is prolonged.
