摘要： A composition for reducing the loss of liquids by seepage through permeable ground surfaces is shown. The composition desirably comprises an aqueous emulsion of asphalt including a cationic emulsifier, a nonionic surface active agent and elastomer solids. The compositions are adapted for spray, roller, brush or flooding, etc., application, on natural and man-made beds of rivers, ponds and other water impoundment and transfer structures. The stability of the emulsion is controlled so that penetration of the soil is achieved, and a flexible water impervious mass is obtained.

摘要： A composition for reducing the loss of liquids by seepage through permeable ground surfaces is shown. The composition desirably comprises an aqueous emulsion of asphalt including a combination of cationic emulsifiers, a nonionic surface active agent and preferably a minor proportion of elastomer solids. The compositions are adapted for spray application on natural and man-made beds of rivers, ponds and other water impoundment and transfer structures. The stability of the emulsion is controlled so that penetration of the soil is achieved and a flexible water impervious mass is obtained.

摘要： A liner is provided for irrigation ditches or the like. The liner is prefabricated in sections many feet long of glass fiber reinforced plastic resin. A section of glass fiber on the order of four to 6 inches long at each end of each prefabricated section is left free of resin. The non-resin covered fiberglass ends are overlapped and coated with resin as the liner sections are applied in the ditch, thereby providing a continuous reinforced liner for the ditch.

摘要： The invention relates to a process and apparatus for the mechanical entrenching of a pipe-line in a sub-aqueous bed, wherein two or more dredging devices are positioned at the two sides of the pipe-line and a bridging framework is provided connecting said dredging devices, said framework being pulled astride the pipe-line while the dredging devices are in action, so that the pipe-line, aided by its own weight, sinks slowly into the trench as it is being dug.

摘要： A marine foundation in a pool is provided by placing a liquid impermeable sheet on the bed of the pool and locating a drain below the sheet. Then, by applying suction force to the drain, a pressure differential is set up whereby the sheet is sealed to the bed and the adjacent bed material consolidates to effectively form a solid mass embedded below and sealed to the sheet. This action affords a large capability for lateral shearing stresses. In use, anchorages, dam-form barriers, storage tanks, and other structures can be tied to the sheet.
摘要翻译： 通过将液体不渗透的片材放置在池的床上并将排水管放置在片材下方来提供池中的海洋基础。 然后，通过向排水口施加吸力，建立压差，由此将板密封到床上，并且相邻的床材料固结以有效地形成嵌入下面并且密封到片材上的固体物质。 这种作用为横向剪切应力提供了很大的能力。 在使用中，锚固物，坝形障碍物，储罐和其他结构可以与片材相连。

摘要： A canal bank retaining wall means and method of making same comprising, an elongate wall poured in place on an earthen canal bank immediately after digging said canal, said retaining wall having expansion joint means therein at spaced intervals along the length thereof for enabling expansion and contraction of said wall upon temperature changes in the surrounding environment. If desired, removable sections may be provided in said retaining wall so that said sections may be removed after the canal is constructed in order that a boat slip or a dock the like may be economically built in said retaining wall. Also, the surface of the retaining wall exposed to the water in said canal may be roughened to provide an ecologically better environment for marine life and other organisms, if desired.
