Full-bonding cement mortar anchor rod and grouting method
The invention provides a full-bonding cement mortar anchor rod which comprises an anchor rod body, wherein an exhaust pipe is arranged on the anchor rod body. A grouting method adopting the full-bonding cement mortar anchor rod comprises following steps: inserting the anchor rod body into an anchor rod hole, setting a grouting pipe at the pipe port, and using anchoring agent or cement mortar for fixing the grouting pipe at the hole port of the anchor rod hole for blocking the hole port; when blocking strength of the anchor rod hole reaches certain strength, grouting for the anchor rod hole from the grouting pipe, and the air is discharged from the exhaust pipe during the grouting process; full-bonding cement mortar anchor rod grouting operation can be achieved by the steps. The grouting operation is achieved after that the anchor rod body is inserted into the anchor rod hole, and the problem of the earlier grouting method which is limited by the cement mortar coagulation time can be solved. Grouting operation can be finished in a concentration mode or batch mode after inserting rod in a large-scale mode, so that the technology is simplified, the anchor rod mounting speed is greatly improved, the labor intensity is reduced, the work efficiency is improved and the construction cost is saved.
