Construction Advantages of Rock Anchoring In constructional engineering rock anchoring support is mainly used for reinforcing and stabilizing stratum and generally it will unite with other supporting structures Specifically one end of rock anchoring is inserted into stratum and the other end connects with other forms of supporting structure Ground anchors soil nails rock bolts Ground anchors or earth anchors are strand wire anchors installed in the ground and prestressed to retain shoring structures These structural elements can used in permanent as well as temporary structures Ground anchors or soil nails can usually be provided in areas where the adjacent land is accessible Soil and rock anchors are available in many versions Common to most of them are an anchor head for transferring tensile force to a Construction a tendon which leads the tensile force into the ground andan anchoring body which transfers the tensile force to the ground Once a rock anchor is successfully in place it provides support and reinforcement to the structure – and also anything built upon it This makes it possible to make use of the mass for heavy duty commercial purposes e g construction projects Rock AnchorSinorock rock anchors are commonly used throughout the civil engineering and tunneling industries They are used to improve the stability and load bearing characteristics of a rock mass In the tunneling industry Sinorock rock anchors are used for horizontal fore poling slope stabilisation at the tunnel portal and for anchoring large section tunnels with high side walls
The Rock Anchor Solution The rock anchor is a complex but efficient foundation solution It reduces the volume of concrete and steel tonnage by using rock as the principal foundation The rock anchor is highly cost efficient feasible and has proven to be very reliable in many projects This solution uses the rock masses as a WTG foundation Rock Anchors are post tensioned bars installed in drilled holes for which at least the entire bond length is located in rock The anchor force is transmitted to the rock by bond between the grout body and the rock Rock anchors can remain unbonded in the freeAnchors in masonry structures are commonly used to attach different structural and nonstructural masonry components Types installation anchorage length and its strength is discussed The structural members which required anchors to be attached to masonry involves ledger beam girders floor and roof diaphragms and other members that Rock Anchoring and Bolt Systems Rod Series Anchors Equipment Installation For catalogue updates visit our web site at necessary safety requirements for the concrete construction anchoring and forming industry All product test data shown 1 A Rock anchors can be used in numerous different engineering situations Their use is typically used in heavy highway work as well as bridge and tunnel construction There are specialized contractors that perform this type of work and the installation of a proper rock anchor is closely tested for strength
