1.Construction preparation
Including preparing sufficient required materials and equipment, leveling the slope, on-site positioning, setting out and positioning, excavating the top foot groove, measuring the water depth and flow rate of underwater construction, etc.
2.Measurement and pay-off
According to the requirements of the design drawings, the slope shoulder, slope foot line and edge line of the bagged sand slope are lofted out, and the elevation points are marked on the steel drill or bamboo pole at the corresponding position (In view of the overall settlement and completion acceptance in the later period, a certain amount of settlement can be reserved )，Make full preparations for Li Po.
3.Bagged sand slope management
Arrange construction workers to bag sand bags. The sand bags should not be too full, and it is advisable to fill about 60%. This is not only convenient for construction workers to move and move, but also conducive to adjusting the smoothness of the slope; Uneven slope should be less than 10 cm， Ensure that the slope is smooth and straight.
4. Laying mold bag
Open the rolled formwork bag on the slope according to the designed position. During the opening process, the formwork bag should always be kept in a downward tension state, and attention should be paid to the overlap width between the formwork bag and the existing formwork bag concrete should always be controlled at 30 cm， Ensure that the joints are tight, and the position of the newly laid formwork bag does not deflect relative to the existing formwork bag concrete, so that the vertical relationship between the edge line of the formwork bag and the axis of the embankment can be well inherited.
5.Fill
Concrete is mainly forced to move under the push of pump pressure, and the concrete pressure decreases rapidly from the filling port to the surroundings with the increase of the distance from the filling port. With the expansion of the concrete filling range in the mold bag, the difficulty of filling increases, and it is necessary to constantly step on and guide.
6.Maintenance of geomould bag
After the concrete is instilled, the surface protection concrete is cured at the same time. Generally, the curing period is 7 days, and the surface of the slope protection is required to be in a wet state during this period.
