Description
Technical field
The present invention relates to mine working engineering apparatus field, more particularly to a kind of laying of roadway support prestressed anchor net sets
Standby and its application method.
Background technology
Anchor net is that one kind is that material works out a kind of webbed safeguard using iron wire or steel wire.
Anchor pole is the body of rod that a kind of tensile strength is better than rock-soil layer, is mutually bonded to form friction inside its one end and rock-soil layer
Resistance, the other end is exposed to be applied pulling force to the body of rod and passes the pulling force at anchor pole head by mounting gasket, pallet and nut outside
To the region of anchoring body, its function is to apply prestressing force to anchor pole.
Anchor pole and anchor net are often used cooperatively supported laneway country rock by mine working, can not only be reinforced country rock and be improved its stabilization
Property, fall and cave in after anchor net can prevent roadway surrounding rock from destroying again.This method is in roadway surrounding rock control because of effect
Significantly it is promoted.Then, with the increase of coal mining depth, roadway surrounding rock stress is also greatly improved, and this causes anchor net
Supporting reply high stress country rock shows problems, especially in face of incompact fractured surrounding rock.First problem is due to anchor net
Control roadway surrounding rock can not be actively tightened without applying prestressing force at the beginning of installation, causes surrouding rock deformation to control in time.
Second Problem be after surrouding rock deformation due to anchor net does not apply prestressing force but the intensity of simple dependence itself resistance country rock
Deform or be scattered, this has resulted in substantial amounts of anchor net and the severe situation such as " the country rock string bag ", rupture has occurred.
The major reason why apply prestressing force to anchor net cannot realize is to go to realize without suitable equipment
The tensioning of anchor net, therefore common bolting with wire mesh remains unchanged sternness in face of deep high stress country rock produced problem, in the urgent need to
To solution.
The content of the invention

3）Top plate contact block is socketed in the end of the jack third level body of rod, the manual liter origin or beginning of very heavy top/bottom part is then pressed
Jack is set slowly to rise until top plate contact block is firmly withstood on back；
4）The insertion of two oil cylinder ends is hooked in the oil cylinder butt hole on plates, and locked with oil cylinder pin, then hydraulic tube
Two ends are connected respectively oil-out and oil return opening in hydraulic pump；
5）It is firmly solid through rockbolt installation hole that the anchor net and anchor net connector one end that step 1 is made are close to wall anchor pole
Due to installation site；
6）The U-type groove hook strip groove profile hole that is hooked on anchor net connector of docking on plate will be hooked and be close to wall, connect
Logical hydraulic pressure pumping source presses starting switch, debugs hydraulic pump normal work；
7）Hydraulic pump stretching switch is pressed, oil cylinder is tensed anchor net connector and then is tensed whole anchor net and is applied prestressing force, so
Keep hydraulic pump voltage supply constant afterwards, while anchor pole is passed through into the connector rockbolt installation hole, it is securely fastened in wall,
Complete the installation of prestressed anchor net.
