Hole sealing device and method for grouting anchor

Abstract

The invention relates to a hole sealing device and method for a grouting anchor. The hole sealing device for the grouting anchor includes an annular baffle with a circular hole, Ma Lisan, water and an annular baffle without holes; the sealing steps are as follows: , mark the position of the grouting anchor, use the anchor trolley or the air gun to drill the hole, the Marysan wrapped in the annular polyester film and the water wrapped in the annular polyester film are set near the tail of the grouting anchor in turn, Then fix the annular baffle with circular holes and the annular baffle without holes, insert the grouting anchor rod and exhaust pipe into the hole at the same time, and use a thin iron wire to pass through the annular polyester film wrapped with Marysan and water. If it is broken, plug the gap of the circular baffle with a circular hole with a sealer, use a BW250 mortar pump to inject grout, and remove the grouting hose and anchor joint after completion. The hole sealing device of the grouting anchor has simple structure, convenient processing, quick and accurate installation during grouting, convenient operation, good hole sealing effect, effective prevention of grout leakage, and is suitable for large-scale production and market promotion.

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...
