초록 ▼

A system providing environmentally friendly pathway tunnel utilizes a bottom configuration with multiple elongated beams and slots. One or more of the beams includes upstanding sedimentation members that are spaced apart along a span of the tunnel. The system interacts with the flowing water and earthen material in the flowing water such that capture and settling of the earthen material at locations along the tunnel occurs to produce a more natural water flow pathway along the tunnel.

대표청구항 ▼

1. A surrounded water flow pathway tunnel adapted to produce an environmentally-friendly tunnel bottom, the pathway tunnel comprising: a bottom configuration formed by a plurality of concrete beams extending in a spanwise direction from one side of the pathway tunnel to another side of the pathway tunnel and that are spaced apart along a depth of the pathway tunnel to define a plurality of elongated through-openings for interacting with flowing water and earthen material in flowing water to enhance capture and settling of earthen material along the pathway tunnel, wherein two or more concrete beams include a plurality of upwardly-projecting sedimentation members spaced apart in the spanwise direction to define gaps between the sedimentation members, wherein a depthwise center-to-center spacing along the pathway tunnel between concrete beams having sedimentation members is between about thirty percent and about seventy percent of a span of the pathway tunnel, wherein multiple concrete beams lack any sedimentation members, wherein for each concrete beam that includes sedimentation members, at least one sedimentation member located on the concrete beam has a height that is greater than a height of another sedimentation member located on the concrete beam;wherein, for each concrete beam that includes sedimentation members, at least one sedimentation member located toward one of the sides of the pathway tunnel has a height that is greater than a height of another sedimentation member located towards a spanwise center of the pathway tunnel. 2. The surrounded water flow pathway tunnel of claim 1 wherein each sedimentation member has a height that is between about ten percent and about twenty-seven percent of a clear height of the pathway tunnel at top dead center. 3. A surrounded water flow pathway tunnel adapted to produce an environmentally-friendly tunnel bottom, the pathway tunnel comprising: one end of the pathway tunnel located upstream along a natural water path and an opposite end of the pathway tunnel located downstream along the natural water path;a bottom configuration of the pathway tunnel formed by a plurality of concrete beams extending in a spanwise direction across the pathway tunnel and spaced apart along a depthwise direction of the pathway tunnel to define a plurality of through-openings extending in the spanwise direction, wherein at least one concrete beam includes a plurality of upwardly-projecting sedimentation members spaced apart in the spanwise direction to define gaps between the sedimentation members, wherein at least one sedimentation member located towards one side of the pathway tunnel has a height that is greater than a height of another sedimentation member located towards a spanwise center of the pathway tunnel. 4. A surrounded water flow pathway tunnel adapted to produce an environmentally-friendly tunnel bottom, the pathway tunnel comprising: a bottom configuration formed by a plurality of concrete beams extending in a spanwise direction and that are spaced apart along a depth of the pathway tunnel to define a plurality of through-openings, wherein at least one of the concrete beams includes a plurality of upwardly-projecting and fixed sedimentation members spaced apart in the spanwise direction to define gaps between the sedimentation members, and at least one concrete beam lacks any sedimentation members, wherein sedimentation members that are located on the at least one concrete beam toward sides of the pathway tunnel have heights that are greater than a height of at least one sedimentation member located on the at least one concrete beam toward a spanwise center of the pathway tunnel.
