The present invention discloses a rainfall sensing two-component high-polymer grouting device and a manufacturing method therefor, and belongs to the technical field of soil protection. The present invention includes an iron box and a water bucket. The water bucket is slidably fitted in the iron box. An inner bottom of the iron box is provided with a pair of lever upturning apparatuses symmetrically distributed about an axis center of the iron box. A lower surface of the iron box is provided with a curing agent ejector and a resin ejector. An end of two lever upturning apparatuses is slidably connected to a low surface of the water bucket. The switches of the curing agent ejector and the resin ejector are respectively connected to the other end of a lever upturning apparatus. A peripheral surface of the water bucket is provided with a permeable hole, and a permeable head is installed on the permeable hole. The present invention utilizes the lever principle of natural gravity and the spring-assisted method to realize the function of high-polymer grouting slope protection, and belongs to an ingenious mechanical structure apparatus. There is no need to stimulate and excite from the external energy, which is environmentally friendly and does not waste the resources and energy.

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 foundation unit for supporting a structure, the foundation unit provided in a plurality of parts, arranged to be coupled together before use, wherein the foundation unit is arranged to be at least partially buried in, and to receive, material.

Landscaping walls, systems and methods of manufacturing and installation of such walls include in aspects a fiberglass based wall having a decorative front side and a back side having at least one conduit where the conduit receives a cable or fastener extending outward from both ends of the conduit to connect to a stake to be inserted into ground adjacent the wall. The conduit in one aspect is a PVC tube mounted vertically against the wall and in aspects is embedded within the wall. The conduit allows for self-adjustment of the cable while also providing solid anchoring of the wall to prevent movement. The wall and system is lightweight, good looking and easy to install.

An apparatus, system and method of connecting an earthen formation to a facing of a mechanically stabilized earth (MSE) structure in which a connector includes a single piece of wire that defines an opening for coupling the connector to an anchor and a pair parallel legs for mechanically connecting the to a soil reinforcing element.

A pile driving rig lower cushion made of material having elasticity modulus of 500-3500 Mpa. The lower cushion comprises two end surfaces and at least one side surface. The first end surface is to be placed against the drive cap of the pile driving rig. The second end surface is to be placed against the end of a pile. The lower cushion has at least one flexible section at the side surface that is more flexible than remaining sections of the side surface in at least one direction. The dimensions of the lower cushion are such that the lower cushion fits snugly into the drive cap housing only when the flexible area is compressed. The lower cushion remains in its place within the drive cap housing due to compressive force caused by the at least one flexible section and friction forces resulting therefrom.

A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.

A modular foundation structure for artificial surface systems may include a plurality foundation sections. Each of the foundation section may comprise a structure base layer, an adhesive layer, and an impact and thermal protective layer. The adhesive layer may cover the structural base layer, and the impact and thermal protective layer may be attached to the structural base layer via the adhesive layer. The foundation sections may be provided as separate foundation sections that may be positionable to be attached to one another to form the modular foundation structure. The foundation sections may be attachable one another with a section adhesive. Embodiments may include a connection edge that may be positioned to surround and abut a perimeter of the modular foundation structure. Embodiments may also include an artificial surface layer that may be positioned to cover an upper surface area of the modular foundation structure.

A method for the construction of an improved tank base. A tank base is constructed for protection against accidental spills and/or leaks associated with a tank battery. The improved tank base comprises at least one part of a suitable substrate, which allows for the adhesion of an elastomer such as polyurea. Polyurea is preferably applied using a spray device which yields an average coverage of about 50-80 mils, and most preferably 60 mils. If more than one substrate is used, one or more substrates can be bound together with a fastening system. Once pressure is applied in the form of weight, the fastening system can be removed, resulting in an improved tank base having at least one seam and impervious to the fluid of the tank battery.

A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.
