Abstract
The utility model discloses a slip -casting anchor cable is by blunt anchor head, expandable casing, the anchor rope body, inner core pipe, outer core pipe, only starch stopper, tray, gasket, spring, nut and constitute. The outside shape of expandable casing is the cylinder, and the sleeve pipe is equipped with one and leads to long cover pipe seam, and the tip that is close to blunt anchor head at the sleeve pipe is equipped with four cover pipe seams, partition expandable casing. It screws up the nut after the design anchor eye degree of depth is reach to the anchor rope, make the tensile or extrusion of afterbody spring production, arouses that the shrink of the anchor rope body is taut, and expandable casing is crowded an expanded anchor rope that forms behind the distending by blunt anchor head. Then carry out slip casting, reinforcing anchor through the central inner core pipe of the body of rod.
Description
Technical field
The utility model relates to a kind of anchoring means, be particularly useful for high slope, roads and tunnels, water conservancy culvert support engineering grouting cable anchor.
Background technology
More and more important to the supporting of underground construction, anchor cable because of its supporting effect good, economic and practical, and by as commonly use support apparatus.But well can not carry out supporting when wall-rock crack grows abundant, rock crushing.
Summary of the invention
The utility model patent provides a kind of grouting cable anchor, and this device can reach resistance to plucking anchoring requirement, and solves the problem of the not recyclable a large amount of waste of anchor cable.
The utility model is a kind of grouting cable anchor, is made up of blunt anchor head, expansion sleeve, inner core tube, outer core pipe, anchor cable body, stop grouting plug, pallet, pad, spring, nut.It is characterized in that: inner core tube and outer core pipe are positioned at the inside of anchor cable, and be threaded connection, anchor cable body is looped around inner core tube and outer core tube-surface, expansion sleeve is surrounded on anchor cable body, expansion sleeve one end withstands on the blunt anchor head of anchor cable head, the other end is connected with stop grouting plug, expansion sleeve is provided with an elongated cover pipe seam, three short seams of sleeve pipe are provided with near the end of blunt anchor head at sleeve pipe, the decile expansion sleeve mouth of pipe, be provided with pallet, pad, nut at the afterbody of anchor cable, between two pads, be mounted with spring.
As improvement, blunt anchor head is hollow structure, and injection slurry can enter anchor hole depths by the structure of hollow.
As improvement, the spring of afterbody is forged by identical material with anchor cable body, and is connected by welding.
As improvement, inner core tube and blunt anchor head are threaded connection.
The invention has the beneficial effects as follows: it is simple that this design has structure, easy for installation, expansion tube expands can provide more powerful anti-pulling capacity for cable bolting technology.During use, after Drilling anchor hole completes, blunt anchor head and inner core tube are connected, puts expansion sleeve, then anchor cable body is sent to the hole depth of design, load onto backing plate, fastening nut can make tail springs produce stretching or extruding, causes the contraction of anchor cable body to strain, causes blunt anchor head to be pulled back, squeezed bulging deformation when expansion sleeve is at one end withstood by pallet, the other end is extruded by blunt anchor head, with anchor hole inwall close proximity.By inner core tube slip casting inwards, slurries are derived by slurry outlet, carry out cementing solidifying to loose rock mass.
