The utility model provides a concrete membrane bag for stone sediment cofferdam protection, its structure is: including membrane bag and filling structure, the membrane bag sets up to two-layer, including membrane bag ground plane and membrane bag top layer, connect through the lacing wire between membrane bag ground plane and the membrane bag top layer, membrane bag bottom is provided with the through bag, be provided with the filling structure respectively with the top in the middle of the membrane bag, the filling structure includes inner support hoop, outer hoop and filling mouth, inner support hoop sets up between membrane bag ground plane and membrane bag top layer, be provided with outer hoop on the membrane bag top layer at inner support hoop place, inner support hoop top, membrane bag top layer and outer hoop bottom fixed connection, inner support hoop bottom and membrane bag ground plane fixed connection, the filling mouth runs through outer hoop, membrane bag top layer and inner support hoop top.
And a baffle is arranged at the position of a filling opening at the top of the inner support hoop and is fixed at the inner side of the inner support hoop through a torsional spring.
The membrane bag grounding layer and the membrane bag surface layer are made of all polypropylene high-strength woven fabric, and the membrane bag surface layer has water permeability.
The penetrating bag is communicated with the membrane bag at the upper end.
The filling structure in the middle of the membrane bag penetrates through the membrane bags on the upper side and the lower side.
The lacing wire is a chemical fiber rope.
More than 1 group of filling structures are arranged in the middle of the film bag.
The capacity of the penetrating bag is 2 times of the same capacity of the membrane bag occupying the ground, and the bottom of the membrane bag can be better fixed.
The utility model discloses a use method does: filling is carried out through a filling opening close to the bottom in the middle, filling is carried out upwards step by step until the membrane bag is filled, filling is carried out through pressing down a baffle of the filling opening during filling, the baffle is returned after the bottom is filled, and then the membrane bag is moved to the filling opening on the upper side for filling.
The beneficial effects of the utility model reside in that: the concrete filling machine is simple in structure and convenient to construct, concrete filling is facilitated through the filling structure, time is saved, filling efficiency is improved, and filling uniformity can be guaranteed; the concrete film bag is adopted for protecting the slope surface of the stone ballast, the construction is simple, the protection effect is good, the stone ballast loss of the cofferdam is avoided, and the safety flood of the dam is guaranteed.
