A prefabricated outdoor support pad is configured for transport from factory to field and above-grade installation on level ground to support a condenser or transformer. A flexible geosynthetic material is joined to the rigid platform along a perimeter and corners of the rigid platform. Upon installation, the geosynthetic material is inserted into the ground, forming an erosion-resisting barrier. Erosion control kits are also provided for outdoor condenser or transformer support pads. One type of the kit comprises a flexible geotextile soil retention barrier sized for attachment to the support pad and insertion into the ground and mechanical attachment members. Another type of the kit comprises a hard-walled ground-insertable soil retention barrier configured to wrap around soil under at least a corner of the support pad when the support pad is placed on grade and mechanical attachment members configured to attach the soil retention barrier to the support pad.

Provided is a soil erosion prevention agent which can suppress the amount of resin used without decreasing soil erosion prevention effect. A soil erosion prevention agent containing a water-borne resin emulsion, wherein: the emulsion has a solid content of 30 to 70 mass %; and the emulsion has a viscosity of 50 mPa.Math.s or lower measured at 30 C. when a water content of the emulsion is adjusted so that the solid content of the emulsion is 40 mass %, is provided.

A substantially rectangular trench shoring sheeting panel made primarily of polyethylene includes at least one pair of hand holes. In some embodiments, the sheeting panel includes a plurality of buttons protruding outwardly from one of the sheeting panel's surfaces. As compared to three-quarter inch FinnForm, the polyethylene sheeting panel typically has (i) equivalent or superior structural properties and (ii) a significantly lower useful-life cost.

A device for and methods of reducing sound vibrations in a liquid resulting from a sound source arranged below the liquid level of a body of water are disclosed. The device includes an elongate tube which can be arranged over the sound source, the tube comprising an outer wall and inner wall with an intermediate space between the inner and outer wall.

An in-situ reconstruction and extension structure of an embankment and a construction method thereof are provided. The structure includes a stepped slope excavated on an existing side slope. A gradient of the stepped slope is the same as that of an extension side slope, the stepped slope is individually intersected with top and bottom planes of existing side slope; a toe of existing side slope is taken as a toe of the extension side slope, and gradient of the extension side slope is determined according to positions of the toe and an expanded width. An outer side of stepped slope is filled with a geogrid reinforcement layer in a layered manner, a slope protection structure is arranged on an outer side of the geogrid reinforcement layer to form extension equivalent side slope; a drainage system is arranged at a bottom of the extension side slope.
