The invention discloses a device and a method for pouring a concrete continuous wall along a gob-side entry in a mining working face. The shape of the
fiber flexible formwork is a cuboid or a cube, and it is composed of a main formwork and a roof formwork. The
fiber flexible formwork is connected with flanges, pouring ports, planting ribs, limit holes, and tie bars. The
fiber flexible formwork is prefabricated, and the
flange hangs the flexible formwork on the
coal seam roof through a single hydraulic prop or anchor rod. The ends are fixed with
pallet nuts, the concrete delivery
pipe is inserted into the filling port and tied, and the
concrete pump is used to inject concrete into the flexible formwork through the delivery
pipe to form a concrete continuous wall. The structure is simple, the construction speed is fast, the labor efficiency is high, the airtightness is good, the
grout is not easy to leak, the concrete filling is dense, the roofing effect is good, the mechanized operation, adapt to the change of the slope of the roof and the floor, widely used in
coal mines, metallurgical mines, water conservancy, underground construction , defense and other industries.
