    摘要： This invention relates to a disposable sewer hose liner that may be used to line the inside of a sewer hose for recreational vehicles, trailers, and mobile homes. The disposable sewer hose liner provides a more sanitary method of disposing sewage and waste water from an RV, trailer, or mobile home and reduces the odor emanating from a sewer hose, the amount of cleaning necessary, and the amount of bacteria or waste that a user comes in contact with when interacting with a sewer hose.

    摘要： Adjustable fixtures for buried tubulars, forming tools for defining a hole in the adjustable fixtures, and/or methods of manufacturing the adjustable fixtures. The adjustable fixtures include a fixture body and a plurality of spaced-apart holes extending between an upper surface of the fixture body and a lower surface of the fixture body. The adjustable fixtures also include a plurality of jack-screw-accepting threaded regions that at least partially defines the plurality of spaced-apart holes. The forming tools include a forming tool engagement structure, a threaded tool end region, and a hole-defining body. The methods include positioning a plurality of jack-screw-accepting threaded regions and a plurality of forming tools within a mold, filling a fixture-defining cavity of the mold with a composite material, curing the composite material, disengaging the plurality of forming tools from the plurality of jack-screw-accepting threaded regions, and removing the fixture body from the mold.

    摘要： A system and method for applying a construction material is provided. The system may include a batching and mixing device configured to mix blast furnace slag material, geopolymer material, alkali-based powder, and sand to generate a non-Portland cement-based material, the non-Portland cement-based material including 4% to 45% geopolymer material by weight; greater than 0% to 40% blast furnace slag material by weight, 10% to 45% alkali by weight, 20% to 90% sand by weight, less than 1% sulfate by weight, and/or no more than 5% calcium oxide by weight; a conduit configured to transport the non-Portland cement-based material from the batching and mixing device; and a nozzle configured to receive the non-Portland cement-based material and combine the transported non-Portland cement-based material with liquid to generate a partially liquefied non-Portland cement-based material, wherein the nozzle is further configured to pneumatically apply the partially liquefied non-Portland cement-based material to a surface.

    摘要： A collector system installed utilizing trenchless or minimally invasive methods and devices configured to intercept and direct surface and/or subsurface fluids to a designated reception location to control groundwater elevations is disclosed. In one aspect, a target collection and drainage area is identified and a gravity drainage pipe is accessed or trenchlessly installed at the target collection and drainage area. The gravity drainage pipe can be accessed at one or more drawdown points. An end of the collection pipe can be connected to the drain pipe. By venting an end of the collection pipe to the surface, surface and subsurface water is hydrostatically drawn into the collection pipe from the target collection and drainage area. The surface and subsurface water can be passively drained from the collection pipe into the distribution pipe and onto the designated reception location providing a green process that eliminates power dependency.

    摘要： A manhole (100) for subterranean installation is described. The manhole (100) comprises a first chamber (110) arranged to receive storm water and a second chamber (120) arranged to receive sewage water. The first chamber (110) comprises a first inlet (111) and a first outlet (112). The second chamber (120) comprises a second inlet (121) and a second outlet (122). The first chamber (110) comprises a first access port (113) opposed to a first base (114) and a first wall (115) arranged therebetween. The second chamber (120) comprises a second access port (123) opposed to a second base (124) and a second wall (125) arranged therebetween. A first normal N1 to the first base (114) extends through the first base (114) and the second base (124). A sewer network 1000 and a method of installing the sewer network are also described.
