Device and method for hole sealing of grouting anchor rod

Abstract

The invention relates to a device and method for hole sealing of a grouting anchor rod. The device comprises an annular baffle provided with a round hole, Marithan, water and an annular baffle without holes. The method comprises the steps of marking the position of the grouting anchor rod, carrying out drilling with an anchor rod trolley and a blower gun, arranging the Marithan wrapped in an annular polyester film in a sealing mode and the water wrapped in an annular polyester film in a sealing mode near the tail portion of a rod body of the grouting anchor rod in a sleeved mode in sequence, fixing the annular baffle provided with the round hole and the annular baffle without holes, inserting the grouting anchor rod and an exhaust pipe into the hole at the same time, piercing the annular polyester films used for wrapping the Marithan and the water with an iron wire, blocking the notch of the annular baffle provided with the round hole with a sealer, carrying out grouting with a BW250 mortar pump, and taking down a grouting hose and an anchor rod connector after the grouting is finished. The device for hole sealing of the grouting anchor rod is simple in structure, convenient to machine, fast and accurate in installation during grouting, convenient to operate, good in hole sealing effect, capable of effectively preventing leakage, and suitable for large-scale production and market popularization.

Description

technical field [0001] The invention relates to a hole sealing device for mines, in particular to a hole sealing device and method for a grouting anchor rod which can effectively seal holes and stop leaks. Background technique [0002] At the beginning of the 20th century, grouting technology has been applied to underground roadways. Since then, grouting method has been widely used in Britain, France, South Africa and the Soviet Union as an important method to prevent water and improve engineering geological conditions in mine construction. In the construction of shafts and lanes in coal mines in my country, grouting technology is mainly used for seepage prevention and water blocking and reinforcement of surrounding rock. [0003] With the development of the national economy, the depth of coal mining in my country has increased year by year, and the section of the roadway has continued to increase. Some mining areas have poor lithology, and have been affected by orogenic tec...
