The present invention discloses an ecological seawall water close side embankment slope drainage structure and a construction method thereof. The ecological seawall water close side embankment slope drainage structure includes a seawall, and further includes a wave dissipation ridge and water collecting wells, wherein the wave dissipation ridge is disposed at an upper side of the seawall, a drainage blind ditch is formed in an upper surface of the seawall, and the drainage blind ditch is matched with the wave dissipation ridge; the water collecting wells are distributed at a lower side of the drainage blind ditch at equal intervals, and lower end portions of the water collecting wells communicate with drainage concealed pipes; and pipe seats are disposed at a lower end portion of an inclined plane of the seawall, lower end portions of the drainage concealed pipes are fixedly connected onto the pipe seats, and flap valves are rotationally connected to lower end surfaces of the drainage concealed pipes. The present invention not only can reduce the erosion degree of sea waves to the seawall, but also can collect seawater going over the wave dissipation ridge and discharge the collected seawater into the sea again.

An erosion control system comprising a plurality of interconnected blocks that each include an upper face, a lower face, multiple sides, and connector recesses disposed on at least some of the sides, with each the connector recesses extending inwardly from an outer surface of the respective side at which it is disposed. Each block is configured to be connected with an adjacent block with one side of each block being disposed adjacent one side of an adjacent block and at least one connector recess of each block being aligned with one of the connector recesses of the adjacent block. The adjacent blocks are connected together at aligned connector recesses by a linkage assembly, with the adjacent blocks being able to pivot relative to each other via the linkage assembly.

A fiber sheet system suitable for controlling erosion and stabilizing soil is described that comprises a fiber sheet comprising a natural fiber felt. A coating composition comprising a natural rubber is adhered to the fiber sheet. The fiber sheet has a top side width less than the height and the length of the fiber sheet. A netting contacts the front and rear sides of the fiber sheet.

This application discloses a geotextile-based structure for soil stabilization, erosion control, and vegetation-growth enhancement that is made from a cage having a hollow interior lined with a geotextile fabric designed to retain fine materials, which cage is attached to a geotextile mat capable of supporting vegetation.

A cellular structure includes a plurality of interconnected cells of fabric material. The cells are at least partially filled with a composite fill material that includes a particulate material and a bonding agent. A cellular unit made up of a plurality of the interconnected cells may have an associated load-bearing frame to enable lifting and/or transportation of the structure. The fill material is preferably resilient.

In a system comprising an customer providing a service to a plurality of client devices, a method and system for providing an customer-specific digital certificate to a client device of the plurality of client devices is disclosed. The method comprises receiving, in an intermediate certificate authority, a pre-generated digital certificate and an encrypted client device private key encrypted according to a private key encryption key PrKEK, receiving, from the client device, a request for the customer-specific digital certificate, the request comprising at least one of client device identifying information and information identifying the customer, the request signed according to a pre-provisioned client device digital certificate, and transmitting the customer-specific digital certificate and the encrypted client device private key to the client device.

An erosion-preventing laminate mat may include a first layer of slivers of a natural material, a second layer of slivers of a synthetic material, and, in embodiments, a third layer of an open mesh. A system for utilizing the erosion-preventing laminate may include a movable frame having an upper surface shaped to pass beneath a substantially flat sheet of tied block mat, the frame including a spindle below the upper surface for supporting a roll of the first mat, the first mat including the first layer of slivers of a natural material, the second layer of slivers of a synthetic material, and the third layer of an open mesh. In embodiments, a system for forming the mat includes a movable frame shaped to pass beneath a substantially flat sheet of the tied block mat, and including a spindle below the upper surface for supporting a roll of the first mat.

The invention belongs to ecological revetments in the technical field of river ecology, which particularly involves an ecological revetment to regulate wandering rivers. The ecological revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing-corridor and a slope green-belt. The ecological landscape-corridor and anchor rod are placed on the upper and middle parts of the pile structure, respectively. In virtue of the innovative structure, the ecological revetment will strengthen the revetment structure, reduce the revetment settlement, prevent the revetment from moving, and enhance the overall stability of the revetment project. The ecological holes exist on the ecological connecting-plates, which is beneficial to the exchange of material and energy from the river course and the bank slope, and the holes could greatly enhance the self-cleaning capacity of the water body. Not only do the plants on the ecological viewing-corridor provide the habitats for the organisms, but also green the revetment.

A geotextile tube includes a bag unit, an extending unit, a main stitch seam, and two auxiliary stitch seams. The bag unit includes a tubular wall and an end wall cooperatively defining a filling space. The extending unit includes two extending parts respectively extending from opposite lateral sides of the end wall and each defining a buffering space. The main stitch seam extends from one of the extending parts to the other one of the extending parts for sealing the filling space. The auxiliary stitch seams intersect the main stitch seam, and are respectively disposed at the lateral sides of the end wall such that the end wall is substantially flat. Each auxiliary stitch seam separates an adjacent buffering space from the filling space.
