The invention relates to a method and a device for producing an injection anchor in the ground, wherein a bore is created in the ground, a hardening material for forming the anchor foot is injected by means of an injection member at least in a partial region of the bore, and after partial, not yet complete, hardening of the material a post-grouting medium is introduced under pressure in a region of the anchor foot via a post-grouting member, by which medium the not yet completely hardened anchor foot is broken up. According to the invention, provision is made for an automatic post-grouting machine to be connected to the post-grouting member, by which machine the post-grouting medium for breaking up the not yet hardened anchor foot is automatically introduced into the post-grouting member at a freely specifiable time.

The present invention relates to a rock anchor foundation structure suitable for a mountain photovoltaic module and a construction method of the rock anchor foundation structure. A technical solution of the present invention is as follows: the rock anchor foundation structure comprises a drill hole drilled in a rock slope, an anchor rod module arranged in the drill hole and a photovoltaic power station module. The photovoltaic power station module is connected with the anchor rod module through a hollow connecting steel pipe; the photovoltaic power station module comprises a bracket welded on the top of the hollow connecting steel pipe, a beam mutually hinged with the top of the bracket and a photovoltaic cell panel arranged at the upper part of the beam. The rock anchor foundation structure of the present invention is suitable for the technical fields of around treatment and foundation engineering design.

A tieback alignment and access device has a hollow core and vertically aligned angled anchor subassemblies that provide attachment points for tieback anchors that pass laterally through the hollow core. The hollow core is configured to allow a cutting tool (e.g., a drill bit) to be inserted therein longitudinally and used to cut the tieback anchors at any time. When cast into a contiguous temporary support-of-excavation wall, the angled anchor subassemblies are set back from an outwardly facing surface of the wall resulting in a smooth surface.

A system and method are provided for a protective barrier liner system on near vertical to vertical slopes of a waste facility. The system includes anchors installed into the side walls of the waste facility, a drainage network including geo-composite drain strips, steel reinforcement, a sprayed water proof membrane, and a pneumatically applied final protective concrete cap layer. The anchors may include soil nails launched from a pneumatic launching device or anchors placed in drilled bores then reinforced with grout. The water proof membrane may be installed between an initial layer of concrete and the final layer of concrete to protect the membrane from damage by facility operations. The steel reinforcement may include wire mesh, whalers, bearing plates, shear studs secured to the bearing plates, and combinations thereof. The system can be constructed in progressive bands spliced together enabling construction of the complete system over a longer period of time.

A retaining wall system includes a plurality of large mass retaining blocks formed with vertically oriented openings passing therethrough for the installation of micro-pile soldier piles. The retaining blocks can be formed of pre-cast concrete and stacked vertically so that the vertical openings are aligned for the installation of micro-pile soldier piles through the stacked retaining blocks and into the bedrock below the retaining blocks. The micro-pile soldier piles can include a steel casing that is installed through the aligned vertical openings to terminate at the bedrock with grout filling the steel casing except for optional reinforcement. The retaining blocks can be formed with cutout key openings that allow concrete to be inserted to provide a key interlock between adjacent retaining blocks to further stabilize the retaining wall. The retaining wall can also include a row of waler blocks that incorporate a pair of tie-back anchors for each waler block.

This patent pertains to secondary containment systems. One implementation includes a support assembly that includes an elongate post member and a stabilization plate. In one instance, a stabilization plate is mounted on the elongate post member to reduce movement of the elongate post member when the stabilization plate is embedded in the ground. Another implementation includes a panel splice assembly including reinforcing members that secure overlapping, corrugated panels.
