2. Designing the vegetation blanket into a structure with three layers of a filling layer, a water bag layer and a plant growth layer and a water bag layer in the middle, wherein the water quantity of the water bag layer is slightly more than the calculated values of the water quantity required by the reaction of binders such as cement, phosphogypsum and the like in the filling matrix of the vegetation blanket and the water quantity required by the plant growth layer; therefore, the water with the required water quantity is filled into the water bag layer when the vegetation blanket is manufactured in advance directly through the calculation process, so that the full reaction of cement, phosphogypsum and other binders in the matrix of the vegetation blanket and the requirement of a plant growth layer can be ensured, the condition of water waste in the traditional construction is avoided, and the rapid greening and ecological restoration of the uneven multi-pit slope surface can be realized when no water source is arranged nearby a construction site or water is inconvenient to draw, the construction process is simple, and the cost is low.

Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
As shown in fig. 1 to 3, the phosphogypsum-based vegetation blanket for rapid greening of multi-pit slope surfaces comprises a whole block vegetation blanket 4 laid in a pit 2 of a side slope 1, wherein the vegetation blanket 4 sequentially comprises a filling layer 4.1, a water bag layer 4.2 and a plant growth layer 4.3 from bottom to top, an anchor 5 can be inserted into and penetrate through the filling layer 4.1, the water bag layer 4.2 and the plant growth layer 4.3, the interior of the anchor 5 is hollow, and a communication hole 5.1 is formed in the surface of the anchor 5.
Furthermore, a hollow cavity 5.2 is formed in the anchor 5, the top of the hollow cavity 5.2 is open, and a sealing cover 5.3 matched with the hollow cavity is arranged. By arranging the cover 5.3, water can be prevented from directly and rapidly leaking out of the top of the anchor 5 when reacting with the filling matrix in the filling layer 4.1 and entering the plant growth layer 4.3; after the above process is completed, the excess water in the vegetation blanket 4 can be drained out by opening the sealing cover 5.3.
Further, when the anchor 5 is inserted into the filling layer 4.1, the water bag layer 4.2 and the plant growth layer 4.3, the position of the communication hole 5.1 in the middle of the surface of the anchor 5 corresponds to the position of the water bag layer 4.2, the position of the communication hole 5.1 in the lower part of the surface of the anchor 5 corresponds to the position of the filling layer 4.1, and the position of the communication hole 5.1 in the upper part of the surface of the anchor 5 corresponds to the position of the plant growth layer 4.3. After the design, when the anchor 5 is inserted into the filling layer 4.1, the water bag layer 4.2 and the plant growth layer 4.3, the anchor can be used as a communicating pipe between the water bag layer 4.2 and the filling layer 4.1 and the plant growth layer 4.3, so that the water in the water bag layer 4.2 can be stably diffused into the filling layer 4.1 and the plant growth layer 4.3 through the communicating hole 5.1.
Furthermore, a semi-permeable membrane 3 is arranged in the hollow cavity 5.2. Because the semipermeable membrane 3 only allows ions and small molecular substances to pass through, water molecules can penetrate through the semipermeable membrane 3 to enter the upper side of the hollow cavity 5.2 and then enter the plant growth layer 4.3 through the communicating holes 5.1, and after the filling matrix in the filling layer 4.1 is mixed and reacted with water, the large molecular substances (such as the large molecular substances existing in cement or expanding agent) in the filling layer are not easy to penetrate through the semipermeable membrane 3 to enter the upper side of the hollow cavity 5.2 after flowing into the communicating holes 5.1 on the lower side of the hollow cavity 5.2, so that the toxic action of the large molecular substances on plant seeds in the plant growth layer 4.3 is effectively prevented.
Further, the anchor 5 is divided into a long anchor and a short anchor, the long anchor is inserted into the bottom of the pit hole 2, the short anchor is inserted into the top of the pit hole 2, the length of the long anchor is 100 to 150cm, and the length of the short anchor is 40 to 50cm. In this embodiment, as shown in the figure, the long anchor bolts can be inserted into the bottom of the pit 2, and the short anchor bolts can be inserted into the top of the pit 2, so that the movement of the vegetation blanket 4 can be effectively prevented. Because the filling layer 4.1 which can be accommodated at the bottom of the pit 2 is larger, fewer short anchor bolts are arranged at the top of the pit 2, and more long anchor bolts are arranged at the bottom of the pit 2, so that the filling matrix in the bottom of the pit 2 has more chances of contacting with water from the long anchor bolts and larger contact area, and the filling matrix in the filling layer 4.1 at the bottom of the pit 2 is ensured to completely react with the water.
Furthermore, the outer surface of the vegetation carpet 4 is closed, and the interior of the vegetation carpet is divided into an upper cavity, a middle cavity and a lower cavity, the upper cavity is filled with plant growth substrates to form a plant growth layer 4.3, the middle cavity is filled with water to form a water bag layer 4.2, and the lower cavity is filled with plant growth substrates to form a filling layer 4.1.
Furthermore, a plurality of water-tight membranes 4.4 are arranged on the filling layer 4.1 from the lower side to the upper side, and the membranes 4.4 divide the internal area of the filling layer 4.1 into a plurality of closed sections. After the filling layer 4.1 is divided into a plurality of relatively independent spaces by the waterproof membrane 4.4, when moisture enters the filling layer 4.1, the filling matrix in each space can fully react with water independently, the reaction of the whole filling layer is more uniform, and the attaching effect of the whole vegetation blanket and the slope surface is improved.
Further, the filling matrix in the filling layer 4.1 comprises the following components in parts by weight: 3 to 4 parts of ceramsite, 5 to 6 parts of vermiculite, 4 to 5 parts of sand, 8 to 10 parts of cement, 2 to 4 parts of phosphogypsum and 0.5 to 1 part of expanding agent; in this embodiment, the expanding agent is a concrete expanding agent or a cement expanding agent. The plant growth layer 4.3 is divided into a base layer and a surface layer; the plant growth substrate in the substrate layer comprises the following components in parts by weight: 98-100 parts of soil and 5-6 parts of organic matter; plant seeds are embedded in the surface layer, and the plant growth matrix in the surface layer comprises the following components in parts by weight: 98-100 parts of soil and 5-6 parts of organic matter. The phosphogypsum is an industrial waste which is difficult to utilize, and is added into the filling matrix, so that not only can the solid waste be recycled, but also the quick-acting phosphorus in the phosphogypsum can enter a plant growth layer to provide certain nutrients for plants; because the volume weight of the phosphogypsum is less than that of the cement, the weight of the vegetation blanket can be reduced by adding the phosphogypsum to the filling matrix to replace part of the cement; meanwhile, the whole vegetation blanket is further lightened by adding the ceramsite and the vermiculite into the filling matrix, and is convenient to carry and transport.
In addition, the invention also discloses a construction method of the phosphogypsum-based vegetation blanket aiming at the rapid greening of the multi-hole slope, which comprises the following steps:
the method comprises the following steps: removing broken stones and floating soil on the slope surface of the side slope 1 and in the pit 2;
step two: one end of the vegetation blanket 4 is placed on the top of the slope, the vegetation blanket is rolled and paved along the slope from the top of the slope to the bottom of the slope after the fixed end, the filling layer 4.1 is filled into the pit 2 by utilizing manual vibration, and the slope surface is kept basically flat;
step three: the anchoring nail 5 punctures the vegetation carpet 4 and sequentially penetrates through the filling layer 4.1, the water bag layer 4.2 and the plant growth layer 4.3, and finally the bottom of the anchoring nail 5 is fixed at the bottom or the top of the pit 2;
step four: the water in the water bag layer 4.2 enters the hollow cavity 5.2 after passing through the communicating holes 5.1 on the surface of the anchor 5, then part of the water flows out from the communicating holes 5.1 on the lower side of the hollow cavity 5.2 close to the filling layer 4.1 and flows into the filling layer 4.1 to be mixed with the filling matrix of the filling layer, and the filling matrix reacts with the water to gradually expand and harden;
step five: the water bag layer 4.2 is extruded in the process that the filling matrix expands and hardens, after the water bag layer 4.2 is extruded, part of water in the water bag layer enters the hollow cavity 5.2 through the communicating holes 5.1 on the surface of the anchor 5, then the water comes out from the communicating holes 5.1 on the upper side of the hollow cavity 5.2 close to the plant growth layer 4.3, and finally the water enters the plant growth layer 4.3 to provide water for the germination of plant seeds;
step six: after the filling matrix in the filling layer 4.1 in the plant growing blanket 4 completely reacts with water, the sealing cover 5.3 at the top of the anchor 5 is opened, and the internal pressure of the plant growing blanket 4 is increased due to the expansion and hardening processes of the filling matrix, so that the redundant water in the water bag layer 4.2 is directly discharged to the outside of the plant growing blanket 4 through the top of the hollow cavity 5.2.
Further, in the third step, the anchor bolts 5 are inserted in sequence from the top of the slope to the bottom of the slope, and before each insertion, after the reaction of the filling matrix in the filling layer 4.1 near the top of the slope with water is completed, the anchor bolts 5 far away from the top of the slope are inserted in sequence. In this embodiment, if the anchor 5 is inserted in order from the toe to the toe, the filling substrate at the toe position will react with the water in advance, and the water in the water bag layer 4.2 will flow downward, so that the water in the water bag layer 4.2 at the toe position is not enough to support the requirement of the reaction of the filling substrate at the toe position, and the pressure at the water bag layer 4.2 at the toe position is the maximum due to the effect of the water pressure in the water bag layer 4.2, if the anchor 5 is inserted in advance, the water will easily leak out from the communication hole 5.1 at the upper side of the anchor 5, so as to cause the phenomenon that the water in the water bag layer 4.2 is lost rapidly, therefore, the anchor 5 is inserted in order from the toe to the toe, so as to ensure that the filling substrate at each position of the whole slope surface vegetation blanket 4 can have enough water to react.
