Description

Continue resigning erosion control support anchor rod and its setting method for bump tunnel
Technical field
The invention belongs to erosion control support anchor rod fields, and in particular to a kind of to continue resigning erosion control for bump tunnel Support anchor rod and its setting method.
Technical background
Bump is one of the most serious disaster encountered in coal production.According to 2500 destructions for having record to China Property bump analysis shows, 90% bump is happened in tunnel.Therefore roadway support is important research topic, anchor Bar anchoring is the important method of roadway support.The deformation in the tunnel with bump danger is larger, and common anchor pole cannot This impact large deformation is born, fracture is easy to happen, thus supporting cannot be played.And existing anchor pole is all to have admittedly Fixed length can cause lane space insufficient, too the anchor pole with regular length if the rock-bolt length reserved is too long It is short to resist impact large deformation, do not have the effect of supporting.
Invention content
For the above technical problems, the present invention provides a kind of continuing resigning erosion control branch for bump tunnel Anchor pole is protected, including high intensity threaded anchor rod main body, anchor pole connecting screw, resigning erosion control energy absorption device, outer barrel and metal dish can be continued;
The high intensity threaded anchor rod main body is fixed in wall, and the surface of the high intensity threaded anchor rod main body is equipped with Anchor pole protrusion, tail end are equipped with internal thread;
The both ends of the anchor pole connecting screw are respectively equipped with to be adapted with the internal thread of the high intensity threaded anchor rod main body External screw thread;The anchor pole connecting screw continues resigning erosion control energy-absorbing for connecting the high intensity threaded anchor rod main body with described Device;
The outer barrel is the tubular structure that cross section is annulus, is embedded in wall;
The metal dish is welded on the tail end of the outer barrel;
The resigning erosion control energy absorption device that continues is in the outer barrel, including can continue resigning erosion control energy absorbing component, can continue and allow Position erosion control energy-absorbing succeeding component and energy absorbing component connecting screw;Wherein, if can continue described in several resigning erosion control energy absorbing component with The dry resigning erosion control energy-absorbing succeeding component that can continue alternately is connected by energy absorbing component connecting screw;It can continue resigning described in each The structure of erosion control energy absorbing component is identical, and each structure that can continue resigning erosion control energy-absorbing succeeding component is identical;
The head end for continuing resigning erosion control energy absorption device is that can continue resigning erosion control energy absorbing component, with the high intensity screw thread The tail end of anchor rod main body is threadedly coupled by anchor pole connecting screw;The tail end for continuing resigning erosion control energy absorption device is that can continue to allow Position erosion control energy absorbing component can continue resigning erosion control energy-absorbing succeeding component, be placed in tunnel;
The both ends setting for continuing resigning erosion control energy absorbing component and resigning erosion control energy-absorbing succeeding component being continued and the anchor The adaptable internal thread of bar connecting screw;The both ends of the energy absorbing component connecting screw are with identical with anchor pole connecting screw outer Screw thread.
The outer barrel can continue resigning erosion control energy absorbing component and can continue resigning erosion control energy-absorbing succeeding component for metal material.
The front end for continuing resigning erosion control energy absorbing component and can continuing resigning erosion control energy-absorbing succeeding component is taper.
The resigning erosion control energy absorbing component that continues is cylinder, and the resigning erosion control energy-absorbing succeeding component that continues is transversal Face is the hexagon of regular hexagon.
The perimeter of section for continuing resigning erosion control energy absorbing component and resigning erosion control energy-absorbing succeeding component being continued respectively with outside The section inner surface perimeter of cylinder is identical.
The inner wall Zhou Changwei 15cm of the outer barrel cross section, length are less than the length of the high intensity threaded anchor rod main body Degree.
It is described to continue resigning erosion control energy absorbing component and to continue the perimeter of section of resigning erosion control energy-absorbing succeeding component be all 15cm, Length is all 20 centimetres;The length of the anchor pole connecting screw and energy absorbing component connecting screw is all 10 centimetres.
Using the above-mentioned setting method for continuing resigning erosion control support anchor rod for bump tunnel, including following step Suddenly:
Step 1, the selection drill bit adaptable with outer barrel drills in wall, so as to get the diameter of hole can be lucky The outer barrel is accommodated, depth is more than the length of the outer barrel, less than high intensity threaded anchor rod main body and can continue anti-suction of stepping down The sum of the length of energy component;
Step 2, the outer barrel for being welded with metal dish is arranged in described hole;
Step 3, the head end of the high intensity threaded anchor rod main body is smeared into resin anchoring agent, by the high intensity threaded anchor Bar main body is sent into the outer barrel, the head end of the high intensity threaded anchor rod main body is peaked to the bottom of described hole, then outside Concrete perfusion in gap between cylinder and the bottom of described hole;
Step 4, by the anchor pole connecting screw, resigning erosion control energy absorbing component and the high intensity screw thread can be continued by described in The tail end of anchor rod main body connects;
Step 5, in wall deformation process, when the tail end for continuing resigning erosion control energy absorption device be exposed to wall with When outer length is more than discreet value, then this step is not executed;When the tail end for continuing resigning erosion control energy absorption device is exposed to lane When length other than road wall is less than the discreet value, then resigning erosion control more described will can be continued by energy absorbing component connecting screw Energy-absorbing succeeding component and the resigning erosion control energy absorbing component that continues alternately are connected to the tail that can continue resigning erosion control energy absorption device End, until the tail end that can continue resigning erosion control energy absorption device, which is exposed to the length other than wall, is more than the discreet value;Institute The numerical value for stating discreet value according to roadway bump presses state deformation and determines.
Beneficial effects of the present invention:
The present invention propose it is a kind of continuing resigning erosion control support anchor rod for bump tunnel, in the deformation of wall Cheng Zhong can continue resigning erosion control energy absorption device and be extended, and then the length of anchor pole can be made to be not limited by roadway space, One straight hair can be made to shoot the effect of erosion control energy-absorbing again, realize protective function;Due to that can continue resigning erosion control energy absorbing component and can continue The cross-sectional shape of resigning erosion control energy-absorbing succeeding component is different, and the shape of outer barrel occurs respective change, makes outer barrel and can continue therewith Resigning erosion control energy absorption device forms constant friction power, absorbs impact energy, ensures that anchor pole is not easy to break.
Reasonable design of the present invention, it is easy to accomplish, there is good practical value.
