Reinforcement mud filling pipe bag

The invention discloses a reinforcement mud filling pipe bag. The reinforcement mud filling pipe bag comprises a bag body. The bag body is formed by sewing double-layer bag cloth. Reinforcement belts are evenly sewn on the bag body and located outside the bag body, and the double-layer bag cloth is connected into a whole through the reinforcement belts. A plurality of slurry inlets are distributed in the bag body and are distributed in a plum blossom manner. Slurry inlet hoses are arranged at the slurry inlets and inserted in the slurry inlets and are fixed with the double-layer bag cloth in a sewing manner. The slurry inlet hoses are in an inverted wedge shape. The outer diameter of the parts, located in the bag body, of the slurry inlet hoses is larger than that of the parts, located outside the bag body, of the slurry inlet hoses. The reserved length of the parts, in the bag body, of the slurry inlet hoses is 1.0-1.5 m, and the reserved length of the parts, outside the bag body, of the slurry inlet hoses i
