Background
A large number of engineering constructions promote the development of social economy, and also seriously damage the local ecological environment, especially form a large number of excavated rock slopes in the construction of highways, mines and hydropower engineering. The engineering excavation not only destroys the original plant layer of the side slope, leads to the breakage of the slope rock mass, but also causes a series of ecological environment problems, such as water and soil loss, debris flow, landslide, loss of biological chains and the like.
When ecological restoration is carried out on the sunken part of the engineering excavation slope surface, the conventional method is often complicated, and a large amount of manpower and material resources are consumed. For a part of engineering side slopes in an area where water cannot be drained conveniently, the sunken parts of the excavated rock side slope surfaces in the area are required to be repaired quickly and efficiently, so that the engineering side slopes are inconvenient to repair. Particularly, for some high and steep rocky slopes, although only point greening is required, the implementation is very difficult due to the construction difficulty and water diversion problems.

2. Designing the filling bags into a structure of a soil matrix bag and a sunken filling bag, wherein the water amount in the water bag is slightly more than the calculated values of the water amount required by the reaction of the cement, the phosphogypsum and other binders in the hardened matrix and the water amount required by the soil matrix; therefore, the water with the required water quantity is filled into the water bag when the filling bag is manufactured in advance directly through the calculation process, so that the full reaction of cement, phosphogypsum and other binders in the hardened matrix and the water quantity required by the soil matrix can be ensured, the condition of water waste in the traditional construction is avoided, the rapid greening and ecological restoration of the concave part of the slope can be realized when no water source or inconvenient water diversion exists nearby the construction site, the construction process is simple, and the cost is low.
3. The phosphogypsum is an industrial waste which is difficult to utilize, and is added into the hardening matrix, so that not only can the solid waste be recycled, but also the quick-acting phosphorus in the phosphogypsum can enter the soil matrix to provide certain nutrients for plant seeds; since the volume weight of phosphogypsum is less than that of cement, the weight of the filled bag can be reduced by adding phosphogypsum to the hardening matrix to replace part of the cement; meanwhile, the whole filling bag is further lightened by adding the ceramsite and the vermiculite into the hardening matrix, and is convenient to carry and transport.
4. When the anchor bolts are inserted into the soil matrix bag and the concave filling bag, the anchor bolts can serve as communicating pipes of the soil matrix bag and the concave filling bag, so that water in the concave filling bag is stably diffused into the soil matrix bag through the communicating holes of the anchor bolts, the water and binders such as cement, phosphogypsum and the like in the hardened matrix fully react, and plant seeds in the soil matrix germinate.
5. Still be equipped with the pellicle in the cavity, because the pellicle only allows ion and small molecule material to pass through, so the hydrone can permeate the pellicle and enter into the cavity upside, then enter into soil matrix through the intercommunicating pore, and behind hardening matrix and the water mixed reaction, the macromolecular material of its inside (like the macromolecular material that exists in cement or the inflation agent) is after the intercommunicating pore that flows into the cavity downside, be difficult to permeate the pellicle and enter into the cavity upside, effectively prevent that these macromolecular material from producing the toxic action to the plant seed in the soil matrix.
6. According to the invention, the filling bag is provided with the sharp spines, and the sharp spines can completely pierce the water bag by pressing the filling bag for the first time after the filling bag is installed, so that the hardening matrix reacts with water; the design can greatly simplify the step of water diversion and water re-pouring hardening in the traditional construction, and workers can conveniently operate on the slope without mechanical equipment.
7. The hardening matrix in the invention can extrude the interior of the concave filling bag in the process of expansion and hardening, so that water in the concave filling bag can automatically enter the soil matrix bag to provide moisture for plant seed germination; the soil matrix water replenishing process by the self-expansion force mode can greatly reduce the labor intensity of workers.

step four: pressing the upper surface of the filling bag (3) for the first time, wherein the water bag (3.4) is punctured by the sharp prick (3.6) to cause water to flow out, then mixing the water with the surrounding hardening matrix (3.5), and the hardening matrix (3.5) reacts with the water to gradually expand and harden;
step five: the hardening matrix (3.5) can extrude the inside of the concave filling bag (3.2) in the process of expanding and hardening, and at the moment, part of water in the concave filling bag (3.2) passes through the separation net (3.3) and is gathered to the position close to the position of the anchor (4), then enters the hollow cavity (4.2) from the communication hole (4.1) at the lower part of the anchor (4), and then exits from the communication hole (4.1) at the upper part of the hollow cavity (4.2) to enter the soil matrix bag (3.1) to provide moisture for plant seed germination;
step six: after the hardening matrix (3.5) completely reacts with water, a sealing cover (4.3) at the top of the anchor (4) is opened, the upper surface of the filling bag (3) is pressed for the second time, and at the moment, redundant water in the concave filling bag (3.2) is directly discharged to the outside of the filling bag (3) through the hollow cavity (4.2) of the anchor (4).
