摘要： Disclosed is a method and system for supporting a pipeline in a trench. The disclosure is directed to the placement of urea-silicate sprayable or pumpable foams into trenches to provide pipeline pillow supports during placement of the pipeline and to form trench breakers in the trench prior to the trench being backfilled. The pillow supports and trench breakers inhibit erosion of the trench prior to and after being backfilled. The urea-silicate foam material has an open cell content of at least 50% to resist floatation, is non-flammable and electrically conductive. Also disclosed is use of supports for placement between the urea-silicate foam and the bottom of the trench to aid in utilization of the urea-silicate foams in cold weather conditions and in trenches with steeply sloped bottoms. Preferably the supports are biodegradable and electrically conductive when wet.

摘要： The present invention is a manually bendable rebar bolt for use in ground reinforcement, particularly in mining operations. The rebar bolt is a steel rod having a length and a width. The cross-sectional area of the bolt taken along the width generally perpendicular to said length has a long axis and a short axis. The bendable rebar bolt can be manually bent in a direction generally perpendicular to said long axis.

摘要： A cable bolt for anchoring, by a curable product, in a hole formed in strata, the cable bolt has a drive head that defines a face end of the cable bolt that, when the cable bolt is inserted into the hole, is to protrude from the hole; an end termination that defines a toe end of the cable bolt at the opposing end to the face end; a first coupling member, and a second coupling member that is configured to be coupled to the first coupling member. The cable bolt further has a first segment that includes the drive head and the first coupling member, and a first set of wire strands that are each secured at one end to the drive head and at the opposing end to the first coupling member; and a second segment that includes the second coupling member and the end termination, and a second set of wire strands that are each secured at one end to the second coupling member and at the opposing end are bound by, and/or secured together at, the end termination. In use, the first and second coupling members are coupled together such that tensile loads in the cable bolt are transferred through the coupled first and second coupling members.
