Abstract
The utility model relates to a hollow grouting anchor rod with a directly readable length, which belongs to the technical field of hollow grouting anchor rods used for engineering construction. The utility model is mainly composed of an anchor head, an anchor rod body, a grout stopping plug, an arch-shaped shim plate and a compression nut. A plastic guide pipe is fixed to the inner wall of the anchor rod body along an axial direction; the close front end of the plastic guide pipe extends into the bottom of the anchor head, the rear end of the plastic guide pipe extends out of the anchor rod body, and the rear end surface of the plastic guide pipe is provided with an end enclosure; a connecting bolt is connected between the plastic guide pipe and the end enclosure. The utility model is also provided with a measuring rod which is axially arranged in the plastic guide pipe, one end of the measuring rod is fixed to the end enclosure and the other end of the measuring rod contacts the close front end of the plastic guide pipe. The utility model has the advantage that after the construction is completed, the length of the anchor rod can be conveniently and visually read to carry out the check and the acceptance of engineering work load.
Description
One, technical field
The utility model relates to geotechnical engineering anchoring utensil, is the used hollow grouting anchor technical field of construction specifically.
Two, background technology
Existing hollow grouting anchor is mainly by anchor head, anchor bar body, stop grouting plug, arch backing plate, compositions such as clamp nut.The anchor head spiral is connected on the anchor bar body.The length check of grouted anchor bar can only be carried out before slip casting, and can't be that the anchor bolt grouting progress is inspected for acceptance to engineering quantity after the construction.
Chinese patent literature CN2644677 discloses a kind of " can detect the hollow grouting anchor of rock-bolt length ".It is interior (hollow measuring tube front end is fixed on the anchor head inner bottom part, and anchor bar body is stretched out in the rear end) of the anchor bar body of existing anchor pole or outer (the hollow measuring tube is bundled in the anchor bar body outside) a hollow measuring tube to be set axially.After anchoring construction is finished, in the hollow measuring tube, penetrate probe, the physical length of measuring anchor pole is to determine amount of work done.It has solved the problem of checking and accepting after the engineering construction.But, there is following shortcoming and defect part in it: one, must penetrate probe when construction and examination, general anchor bar body length specification is 2.5m, 3m, 3.5m,, 4m etc., penetrating the probe that reaches 3-4m is cumbersome and hard thing, if enter foreign material accidentally in the hollow measuring tube, even checking and accepting can't be carried out.Its two, the hollow measuring tube is positioned at anchor bar body, and has only front end to fix (with anchor head), the inhomogeneous active force during slip casting can make its torsional deformation.
Three, utility model content
The purpose of this utility model provides a kind of hollow grouting anchor that can intuitively read rock-bolt length, makes anchor bolt grouting construction back measure more convenient to the examination of rock-bolt length.This novel purpose is realized by following technical scheme: a kind of hollow grouting anchor that can intuitively read rock-bolt length, mainly by anchor head, anchor bar body, stop grouting plug, the arch backing plate, clamp nut is formed, and it is characterized in that described anchor bar body internal face upper edge axial restraint has plastic catheter, the closed front of plastic catheter stretches into the anchor head bottom, stretch out beyond the anchor bar body its rear end, and be equipped with an end socket on the end face thereafter, and coupling bar is connected between plastic catheter and the end socket; Also have the measuring stick that axially is arranged in the plastic catheter, the one end is fixed on the end socket, and the other end contacts with the closed front of plastic catheter.
The material of described end socket and coupling bar is plastics.
Described connection locking bolt is three, on the uniform circumference that is arranged on plastic catheter and end socket.
Technique scheme as seen, during construction, it is among the anchor hole that the anchor bar body that installs anchor head is inserted rock-boring, hangnail on the anchor head tangles anchor bar body, stop grouting plug, arch backing plate, nut are installed again, anchor pole is fixed, connect slurry filling machine, the slip casting of machining, slurries carry out grouting filling to anchor hole through anchor bar body inner chamber and three perforates from anchor head.Carry out slip casing by pressure improvement rock texture as needs, only need that slurry filling machine pressure is transferred to design pressure and get final product.There is the pressure injection slurry not only can the filling anchor hole, and the area that takes place in the crack, slurries permeate the crack under the effect of grouting pressure.
This novel advantage that is compared with prior art had is: after 1, anchor bolt grouting is finished, only need the plastics coupling bar is twisted off, the related measuring stick of end socket is extracted out from anchor bar body, check the measuring stick high scale, can read rock-bolt length easily and intuitively.2, the plastic catheter of built-in measuring stick is fixed along the anchor bar body internal face, and the fixed form of a this line is more more solid and reliable than the fixed form of an existing point, can make plastic catheter unlikely stressed irregular and be out of shape in the slip casting process.
Four, description of drawings
Accompanying drawing is this novel structure chart.
Five, the specific embodiment
In the accompanying drawing, anchor head 1 is screwed on the anchor bar body 2, and stop grouting plug 3, arch backing plate 4 are enclosed within on the anchor bar body, and clamp nut 5 is screwed on the anchor bar body, and stop grouting plug and arch backing plate are pressed on the anchor hole.Plastic catheter 6 is fixed on the anchor bar body internal face vertically, the sealing of plastic catheter front end, and stretch into the anchor head bottom, and stretch out outside the anchor bar body its rear end, and end face is provided with an end socket 8 thereafter, and coupling bar 9 is connected between plastic catheter and the end socket; The measuring stick 7 that has scale (as being the length scale of 50 centimeter one lattice) axially is arranged in the plastic catheter.Measuring stick 7 one ends are fixed on the end socket, and the other end contacts with the closed front of plastic catheter, and promptly measuring stick and anchor bar body are isometric substantially.End socket 8 and coupling bar 9 can adopt plastic production.Coupling bar can be 1-3, on the uniform circumference that is arranged on plastic catheter 6 and end socket.
Claims (2)
1, a kind of hollow grouting anchor that can intuitively read rock-bolt length, mainly by anchor head, anchor bar body, stop grouting plug, the arch backing plate, clamp nut is formed, and it is characterized in that described anchor bar body (2) internal face upper edge axial restraint has plastic catheter (6), the closed front of plastic catheter stretches into anchor head (1) bottom, anchor bar body (2) is stretched out in addition in its rear end, and is equipped with an end socket (8) on the end face thereafter, and coupling bar (9) is connected between plastic catheter (6) and the end socket (8); Also have the measuring stick (7) that axially is arranged in the plastic catheter (6), the one end is fixed on the end socket (8), and the other end contacts with the closed front of plastic catheter (6).
2, anchor pole according to claim 1 is characterized in that, the material of described end socket (8) and coupling bar (9) is plastics.
