Provided is a lateral water intake structure for preventing silting of bed load and floating debris, which is provided at a river bank. The lateral water intake structure includes: a diversion canal, a guiding wall structure, a shaft-shaped water intaking space, and a trash rack. The lateral water intake structure functions to prevent the floating debris from gathering at the surface of the trash rack and reduce a risk that the trash rack is damaged by water pressure and hitting of the floating debris. Meanwhile, by using a water flow in the watercourse to continuously wash the floating debris near the trash rack, maintenance costs of removing the floating debris at the trash rack manually or mechanically can be reduced.

A catheter housing for securing a catheter device coupled to a catheter. The catheter housing can include a cover and a hub. The catheter housing can additionally include a lock in an interior portion of the cover that secures a portion of the catheter device coupled to the catheter. The catheter housing can additionally include a bridge configured to contact and/or secure a portion of the catheter device and align the catheter device so that the catheter remains inserted at a natural or proper insertion angle relative to a patient's vein. The catheter housing can include one or more wings extending outward from a cover of the housing that can help secure tubing coupled to the catheter device.

The present invention relates to a water intake structure according to a first aspect. The structure includes a plurality of elongate members. The elongate members couple together and are trapezoidal in lateral cross-section. There is also provided a water intake structure according to a second aspect. The structure includes a plurality of elongate members. The elongate members couple together. Each said elongate member has first and second exterior surfaces that are planar and a third exterior surface that is outwardly concave.

A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.
