摘要： A locally-anchored, self-drilling, deformable, hollow rock bolt has one or more intermediate local anchors each of which is flanked by two relatively elongateable shank segments. After grout is supplied through the hollow interior of the rock bolt while the rock bolt is in the drilled borehole, each anchor fixes the bolt to the rock mass, whereas the adjacent smooth shank segments can deform and even yield to accommodate rock fracture. The local anchors may be of relatively short extent when compared to the shank segments. One or more of the intermediate anchors could be formed by a coupler connecting adjacent bolt sections together and/or by shaping the bolt and/or by providing an external anchor. The innermost end of the rock bolt may be formed from or bear a drill bit. The drill bit can have dual functions of drilling the borehole and serving as the innermost anchor of the bolt.

摘要： For drilling holes in soil or rock material and for fixing an anchor in a borehole, an expanding element fixed to a drill or anchor rod and a spreading element are introduced with the rod into the soil or rock material, the spreading element is expanded to butt against the wall of the borehole after completion thereof by the rod. The expanding element being retracted into the spreading element. The rod is secured by an anchor plate on an outer side of the borehole. After expansion of the spreading element, the rod is subjected to a rotary movement in the direction of the interior of the borehole until there is abutment with the interior of the borehole. The rod is fixed to the outside of the borehole by bracing the anchor plate by means of a nut.

摘要： The invention provides an injection, sealing, valving and passageway system for use with hollow rock bolts and hollow injection bars used in mining, civil engineering, tunneling and construction including use with hollow self drilling rock bolts. The invention comprises a plurality of passageways with one or more one way flow valves along the passageways. The invention enables one or more fluids to be pumped into a hollow rock bolt or other hollow elongate member either sequentially or simultaneously without cross contamination of fluids in another passageway or back flow of fluids along the wrong passageway. The invention is typically used to install self drilling rock bolts whereby a drilling fluid is initially pumped through the hollow bolt during the drilling cycle, and then a two part chemical resin or cement grout is pumped through the hollow bolt to anchor the bolt in the borehole.

摘要： In an anchoring device, a drill head and expansion element(s) are configured to cooperatively interlock with each other to provide for directed movements of the drill head relative to a longitudinal axis of the shaft. Co-operating contact surfaces between the drill head and the expansion element(s) are configured such that relative longitudinal movement of the drill head with respect to the expansion element(s) displace(s) the expansion element(s) outwardly so the expansion element(s) can provide frictional contact with a borehole once inserted therein.

摘要： The present invention relates to rock bolts which may be used in mining applications. The rock bolt of this invention includes a mechanical anchoring arrangement to facilitate retaining the rock bolt in a borehole, and also a drill bit to enable self drilling of the rock bolt. Rotation of the rock bolt about an axis of the rock bolt in a first direction causes the drill bit to drill into rock and to create a borehole to receive the rock bolt. Subsequently, rotation in the opposite direction actuates a mechanical anchoring arrangement to anchor rock bolt.

摘要： A corrosion-protected, self-drilling anchor and an anchor subunit and to a method for the production thereof is provided. A self-drilling anchor of the invention includes a number of anchor subunits, each with a hollow bar element, which are connected together by the formation of an axial bell butt joint to form a connected pull and pressure member. The first subunit t its end has a drill bit and the subunit is connected non-rotatably with its end to a drilling and injection device. It is provided according to the invention that each hollow bar element is surrounded by a sheathing except for its end sections and the annular gap between the sheathing and hollow bar element is grouted with a first corrosion protection compound. A coupler in the area of the bell butt joint fits tightly against the sheathings of the two hollow bar elements which are part of the bell butt joint. The hollow space between the coupler and hollow bar elements is filled with a second corrosion protection compound. A method of the invention provides for the prefabrication of a number of anchor subunits at the factory to drill these into the substrate at the site of the anchor to be produced and thereby for connecting them together with the formation of bell butt joints, whereby in the area of the bell butt joint a coupler fits tightly against the ends of two neighboring sheathings and the hollow space between the coupler and hollow bar element is filled with a second corrosion protection compound.
