Devices and methods for streamlining the completion of work functions within a lateral pipe connected to a main pipe. A variety of different lateral devices may be used to aid in the process of relining the main or lateral pipe. A lateral location device is inserted into the lateral pipe prior to relining of the main pipe and is subsequently used to aid in the conventional cutting of the main-lateral interface. A lateral cutting device actually performs the main-lateral cutting process from within the lateral or from within the main. A lateral inspection device crawls up the lateral for inspection via camera. A lateral relining device aids in the placement of a liner used to reline the lateral pipe. Each of these interchangeable work functions may be optional performed by one or more lateral devices, often carried and inserted by a delivery device.

The reducer drain members have non-parallel upper and lower edges, such that one end of a reducer drain member is taller than its other end. An assembly is created such that the slope of the upper edges of the reducer drain members is not parallel to the drainpipe axis, allowing the upper edges of the reducer drain members to correspond to the slope of the ground surface.

A single-module deployable bolted flange connection apparatus (10) makes up standard flange joints (24, 32) for various pipeline tie-in situations, such as spool piece connection and flowline-tree connections, without the use of divers and auxiliary multiple pieces of equipment. An outer Flange Alignment Frame (FAF) (14), carries one or more claws (38) for grabbing the pipe/spool to provide flange alignment. The claws are suspended and driven by a novel arrangement of five hydraulic rams (412-420) A crash-resistant inner frame (148) houses complete connection tooling (150, 152 etc.) The tooling performs the final alignment steps, inserts the gasket and studs, applies the required tension, and connects the nuts. Studs and nuts are stored separately from the tooling in an indexed carousel, to permit multiple operations, reverse operations (disconnection), and re-work of failed steps, all without external intervention.

A river course ecological treatment system essentially comprises a plurality of ecological biological water purification systems and a plurality of plastic retaining dams disposed along a river course, and at least one damp land ecological water purification system disposed beside the river course. The plastic retaining dams separate the river course into several retaining regions. The ecological biological water purification systems purify the water in the retaining regions by microorganism purification. Afterward, the water purified by the ecological biological water purification systems is introduced into rainwater channels of the at least one damp land ecological water purification system. After being purified by aquatic plants in the at least one damp land ecological water purification system, the water returns to the retaining regions the downstream portion of the river course. Therefore, a river improvement system capable of performing both step-by-step treatment and joint treatment is effectuated.

An elongate linear drain for a shower includes an elongate, channel-shaped drain body, an elongate, channel-shaped extension that is connectable to either end of the drain body, elongate inserts that are nested within the drain body and the extension, and end walls that cap the ends of the drain body and the ends of the extension.
