The present application relates to the technical field of a bathroom equipment, and particularly to a flow guide assembly and water seal floor drain. The water seal floor drain includes a floor drain seat, a floor drain cover, a fixing body, a water seal body assembly, a lifting rod and a sealing cover, in which an upper end of the lifting rod is slidably connected to the water seal body assembly, and an upper end of the sealing cover is rotationally connected at a center to the lifting rod. The flow guide assembly further includes a guide component provided at a side of the sealing cover departing from the lifting rod. A lower surface of the guide component acts as a second guide surface, and is configured to bulge downward. In addition, the present application relates to a flow guide assembly for guiding the flow of a fluid.

Modular floor drain systems that include symmetric substrate segments each having outwardly extending flanges for overlapping an adjacent edge of the other substrate segment. The system also includes a drain segment connected to the two or more symmetric substrate segments via at least one of the outwardly extending flanges. The symmetric substrate segments have identical configurations enabling interchangeable use thereof and complementary mating for ease of installation of the modular floor drain system. The substrate segments may have hinges for bending the symmetric substrate segment to allow for folding thereof.

A modular deck drain system comprising a bottom channel and an upper cover. The bottom channel has a pair of opposed side walls and a bottom surface coupled to the side walls. The bottom channel also has a plurality of stabilizing members coupled to and extending from an external surface of the bottom channel, and at least one modular junction node. The upper cover is configured to couple to the bottom channel. The upper cover has two upper walls, each wall having a top end and a bottom end, and the top end of each wall is coupled to an upper lip. A narrow top opening is formed by the upper lips. The upper cover has at least one cutline.

A storm water capture and filtration system may secure in a catch basin or other area subject to flows of water from streets, channels, and the like as a result of run off from storms. A filter system may include a capture portion including attachment mechanisms, a funnel, various supports, and a filter hanger designed and calculated to capture all water entering a storm water inlet and directing it toward a bag filter. A gap is provided between a funnel and filter hanger in order to provide accommodation for overflow, while an anti-backflow skirt on the filter bag resists flushing of captured pollution out of the bag in overflow condition.

A method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes applying a polymeric concrete material to the bottom wall and side walls of each concrete section preferably using a spray application. The concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout or non-sag seal can be preferably applied to the connections.

A storm drain filter system (10, 100) includes a closure (31, 131) for selectively closing a filter (26, 122) when the latter is filled with sediments (13) or when water flow (11) into the storm drain filter system (10, 100) exceeds a filtering capacity of the filter (26, 122). When the filter (26, 122) is closed, water (11) incoming at the storm drain filter system (10, 100) is diverted to a portion thereof allowing water (11) to enter a storm drain (12) without filtration. In some embodiments, any sediments (13) already collected in the filter (26, 122) are prevented from exiting the filter (26, 122) when the filter (26, 122) is closed.

A floor drain includes a channel body defining a longitudinal direction and including two outflow channels which extend parallel to each other, each having a channel bottom and two channel walls. A connecting bar extends horizontally and connects the upper mutually facing longitudinal edges of the channel walls. An outflow opening interrupts the connecting bar and the channel walls directly connected thereto. An outflow fitting is arranged below the channel body and surrounds the outflow opening in the circumferential direction. At least one slat-like connecting element is detachably mounted on the channel body and is designed in such a way that it continues the connecting bar and the channel walls in the region interrupted by the outlet opening.

A stormwater capture housing system designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility. The system comprises a housing unit with top grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box. The screen box ensures that the solid waste is collected while the water filters into a clean water area. The screen weir also filters solid waste and is further configured to allow for an overflow of stormwater and solid waste. Another section of the top wall has a filled grating configuration that allows for stormwater to drain without passing any solid waste to prevent flooding, also enabling access to the internal components of the housing system.
