The present invention relates to a movable protection wall having grout holes. The movable protection wall comprises: a lattice reinforcement wire net arranged as a main frame of the protection wall as a median for the safe driving of a vehicle and the prevention of accidents; a protection block having groove parts vertically formed in both ends; a plurality of fastening rings formed in one side of the groove parts of the protection block to fasten protection blocks to each other and having one side fixed inside the protection block and the other side having a ring shape; fastening units inserted in a hole penetrating the fastening rings in a state where the fastening rings of the protection blocks vertically alternate to fix the protection blocks in the bottom of the groove parts of the protection blocks; a coupling groove formed in the lower part of the protection block under the last groove part and having a groove shape recessed in the protection block at a predetermined size; a coupling protrusion formed of concrete having a steel bar or a steel reinforcement while protruding from the bottom of the other side of the protection block at a predetermined size and inserted in the coupling groove, formed in the other side of the protection block under the last groove part, integrally protruding from the protection block, and inserted in the coupling groove to be fixed; and grout holes penetrating from the front and rear surfaces of the protection block to the underside of the protection block to be bored to incline one surface of the protection block positioned toward a road at an abtuse angle to a vertical surface. When the protection blocks are fixed to each other, the coupling protrusion is inserted in the coupling groove to be fixed to make the height of the protection wall constant in the connection of the protection blocks. The fastening rings vertically alternate to each other to be fastened by the fastening units to obtain the convenience of coupling and fixation in the installation of the protection wall and stiffness and stability after the installation. |
