A system and method to provide water and sediment flow through a rock jetty, which includes a plurality of collection components mounted along a forward face of the rock jetty, each collection component having a plurality of flow pipes to receive water carrying sediment; a principal flow pipe to receive flow from the plurality of flow pipes and to carry water and sediment a predetermined distance to deposit at the rear of the jetty; a continuous trough mounted on the jetty forward face to efficiently capture water and sediment at entrances of the plurality of flow pipes; and a filter screen covering the entrance of the trough to allow water and sediment to flow into the trough and to prevent large rocks and other debris from entering. Sections of principal flow pipe may be removed when sufficient quantity of sediment has been deposited, so that additional sediment can be deposited.

An apparatus and method for controlling water flow, soil erosion, and / or sediment flow in and around a construction site. The apparatus includes a three-dimensional, water-permeable polypropylene filled geotextile pocket that is secured to the ground with a supporting structure. The apparatus includes a tail portion that is placed flat against the ground, facing upstream against the direction of water flow. The tail portion can be secured with pins that provide protection against movement of the tail portion and reduce an amount of sediment passing under the apparatus.

The invention further discloses a method for performing observation testing by adopting the system. According to the system and the method, visual environment is realized through the transparent soil, the transparent model soil tank, and the transparent shield tunneling machine model, and by utilizing the commercial PIV digital image processing system, the flow characteristics of the muck in the soil chamber and the deformation characteristics of the soil body in front of an excavation face when the simulation testing device of the excavation system of the reduced-scale single-circle shield tunnels are directly observed and recorded.

The invention discloses a transverse distribution lamella purifier and a settling pond with the same. The transverse distribution lamella purifier is formed by arranging multiple settling modules. Each settling module comprises a guide plate, a plurality of wing plates arranged in a flow direction of fluid, a first flow baffle and a second flow baffle, wherein the first flow baffle and the second flow baffle are arranged in the front and rear of the guide plate respectively. The inlet end of each wing plate is connected with the corresponding first flow baffle, and the outlet end of each wing plate is connected with the corresponding second flow baffle. The wing plates include first and second wing plates divided along the flow direction of the fluid, the first wing plates disposed inside the settling modules are used for guiding sediment, and the second wing plates projecting out of the settling modules are used for guiding the fluid. A sediment flow passage is formed between one side of each first wing plate, close to the corresponding guide plate, and the corresponding guide plate, and the wing plates are inclined so that the sediment can flow into the passages easily. Compared with the existing settling pond having the same size, the settling tank has the advantages that purifying efficiency is more than tripled, production cost is reduced greatly, and purifying efficiency is improved significantly.

The Invention is an underground storage tank apparatus and method. A buried underground storage tank has a tank sump and a manway defined by a manhole skirt side wall communicating from the surface of the ground to the tank sump. A sediment trap is disposed annularly within the manway and intercepts water and sediment flowing down the manhole skirt wall. An inside wall of the sediment trap is in an annular spaced-apart relation with a tank sump perimeter watt, which together define an annular space interior volume that receives water that overtops the sediment trap inside wall and which receives liquid that overtops the tank sump perimeter wall.

The invention relates to a device for improving the loading efficiency of a trailing suction dredger, which is installed in the cabin of the dredger and used to prevent sediment from flowing out of the overflow tube in the cabin, including: an air injection device and a lifting device , the air injection device includes an air pump, an air delivery hose and at least one bubble curtain generating tube, the air delivery hose communicates with the air pump and the bubble curtain generating tube, the air outlet end of the bubble curtain generating tube is arranged toward the overflow cylinder, the lifting device and the bubble curtain generating tube The one-to-one connection can drive the bubble curtain generating tube to move up and down. Implementing the embodiment of the present invention has the following beneficial effects: the air pump can generate a large number of bubbles near the overflow pipe through the bubble curtain generating tube to form a bubble curtain. When the water containing sediment flows toward the overflow pipe, the bubbles prevent the sediment from flowing with the water Continue to move, so that the sediment is kept in the cabin, while the water flows away from the overflow pipe, which greatly reduces the loss of sediment at the overflow tube, and effectively improves the loading efficiency of the dredger.

The invention discloses a sand blowing device for controlling the Yellow River, which comprises a main board, the main board is rectangular, the two ends of the main board are in the shape of arcs, four first installation holes are opened inside the main board, and the four A dust raising device is fixedly installed inside the first installation hole, and power devices are fixedly connected to the tops of the two dust raising devices. By installing a dust raising device inside the main board and installing a power device on the top of the dust raising device, the flow of the Yellow River can make the power device rotate, and the rotation of the power device can drive the fan blades and brush holders inside the dust raising device to rotate, and the brush The rotation of the frame can make the sediment on the riverbed float, and then through the rotation of the fan blades, the floating dust can be blown to the top of the equipment, and the sediment can flow downstream through the flow of the Yellow River water, so as to achieve the effect of sand cleaning. As a result, by arranging multiple lifting and sinking devices inside the rotor, the range of dust raising is increased and the efficiency of sand raising is improved.
