A vehicle is provided for installing in a prepared area along a ground surface a protective structural support proximate a buried pipeline in an automated manner. The vehicle includes a chassis with a plurality of wheels and a payload release mechanism coupled to the chassis and including a roller for holding the protective structural support. The payload release mechanism is configured to dispense and lay down the protective structural support in the prepared area. The vehicle includes a liquid dispensing mechanism that is coupled to the chassis and is located downstream of the payload release mechanism. The liquid dispensing mechanism includes a liquid source and a dispenser that is in fluid communication with the liquid source and is configured to dispense liquid across a spray area.

A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.

Methods for increasing soil stabilization utilizing an anionic surfactant and a solution. Varying amounts of the anionic surfactant sodium dodecyl sulfate (“SDS”) is added to soils along with a solution of calcium chloride. A mixing procedure is then used to mix the SDS-soil matrix with the calcium chloride solution. The micelles surround the soil particles, creating a matrix, and then the calcium ions of the calcium chloride solution bonds the micelle complex together. The resulting calcium dodecyl sulfate (“CDS”) complex is very hard, relatively insoluble, and very strong. This process can be reversed by exposing the CDS complex to seawater. The sodium ions of the seawater exchange with the calcium ions of the CDS complex reforming the SDS surfactant.

A self-contained soil stabilization system may include a chassis, at least one motor coupled to the chassis configured to actuate a locomotor configured to move the chassis, and a hopper disposed on the chassis and configured to contain a payload configured to stabilize soil. The payload may be deployed from the hopper to stabilize soil in a target soil stabilization area. In some embodiments, the payload may be a chemical soil stabilization agent, a pile, or a sheet pile.

A method for altering a characteristic of the ground. The method comprises the steps of preparing a lignocellulosic material, suspending the lignocellulosic material in a slurry to create a lignocellulosic slurry, and creating a fluid movement of the lignocellulosic slurry. The method further includes the steps of resuspending a portion of the lignocellulosic slurry with the fluid movement; and injecting the lignocellulosic slurry below the surface of the ground.

The present invention discloses a method for remedying sandy land by using a simulated loam substrate spray-seeding technology. The method includes the following steps: first, carrying out a simple sand-fixing treatment to lay a metal mesh in sandy land, the metal mesh being fixed to the surface of the sandy land by a sand-fixing pile; second, spray-seeding a seed into the sandy land by means of simulated loam substrate spray-seeding; and finally, when the spray-seeding is completed, carrying out maintenance management, including adding a protective plate around the metal mesh, covering with a non-woven fabric, watering, fertilizing, reseeding, and post-monitoring. The method for remedying sandy land by using a simulated loam substrate spray-seeding technology provided by the present invention adopts a two-layer spray-seeding method, and rapidly simulates a simulated loam substrate suitable for plant growth in natural world by bionics; the simulated loam substrate has a good water retention capacity, which is conducive to a higher germination rate of a seed, root development, a microbial activity, nutrient transformation, and plant growth and development; and with less investment and a quick effect, the method is suitable for large-scale sand control.
