A pocket structure for receiving containerized plants is sloped and hung from a wire of a wire basket. The pocket structure includes hooks, an irrigation fitting and corresponding drip channel to transmit water toward the rear of the pocket, and slots in the walls. The mesh units include braces and are sized for shipping. An earth wall is formed of the mesh units and pockets, and includes irrigation tubing.

Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.

In certain embodiments, a sand-boil filter includes a hollow, conical, water-porous structure made of a mesh material having spaced mesh holes. The filter is inserted narrow-end down into a sand boil to allow water to flow from the ground through the mesh material and out the top of the sand boil, while blocking solid matter larger than the mesh holes from passing through the mesh material. In some implementations, the filter is filled with gravel that holds the filter in place while allowing water to flow out of the sand boil. Such filters prevent sand boils from growing while relieving the underground hydrostatic pressure that created the sand boil in the first place and inhibiting subterranean erosion that can cause failure of a nearby levee. The conical shape provides relatively large surface area that inhibits clogging and allows each filter to be used for a range of different sand-boil sizes.

An electrically conductive geosynthetic clay liner incorporating an electrically conductive textile graphene.

A silt fence patch for repairing damage to silt fence is disclosed. A silt fence patch may comprise geotextile fabric, an adhesive layer, and a backing. The backing may include indicia of patches, such as patch weave direction, user instructions, or logos. A silt fence patch sheet may comprise multiple silt fence patches. The sheet may include a backing with indicia of each patch, or indicia of the patches may be printed directly on the sheet fabric. A method of repairing damage to silt fence may comprise identifying damage to the silt fence. A damage boundary may surround the damage. The method may further comprise identifying a patch size to cover the damage boundary. The method may further comprise selecting a patch having the identified patch size. Additionally, the method may comprise applying the selected patch to the damage boundary and smoothing the patch over the damage boundary.

The pocket structure includes hooks, an irrigation fitting and corresponding drip channel to transmit water toward the rear of the pocket, and slots in the walls. The mesh units include braces and are sized for shipping. An earth wall is formed of the mesh units and pockets, and includes irrigation tubing. The components may be formed into a palletized kit.

A composite utility tunnel including a plurality of prefabricated tunnel units which are connected to one another. Each tunnel unit includes a tunnel body and a support component. The tunnel body includes a liner layer, a structural layer and an outer protective layer from inside to outside in the radial direction. The liner layer includes a flame-retardant resin and a flame-retardant fabric. The structural layer at least includes a plurality of bamboo strip layers including winding bamboo strips to which a water-soluble resin is adhered. The outer protective layer at least includes flame-retardant resin; and the support component is secured to an inner surface of the tunnel body.
