S7; installing a fastening plate; after the anchor rod is driven in, the thread section of the end part of the anchor rod is utilized to be leaked, and a fixing plate is arranged. The middle part of the fixing plate is provided with a threaded hole and is screwed on the threaded section, so that the fastening plate is ensured to rotate to the position during installation until the anchor pads around the fastening plate deform slightly.
S8; watering and maintaining; after the anchor pad is paved and reinforced, clear water is sprayed on the surface of the anchor pad to completely wet the anchor pad, the anchor pad is sprayed once in the morning and at night, the sprayed water is sufficient to keep humidity, personnel are strictly prohibited to walk on the anchor pad during maintenance, and seeds are planted in the anchor pad to grow into green skin to form the biological protection blanket.
2. The river bank slope multiple ecological anchor mat protection construction method as claimed in claim 1, wherein when the materials are laid, overlapping of the materials is paid attention to, and the materials are guaranteed to be tightly attached to each other.
3. The river bank slope multiple ecological anchor pad protection construction method according to claim 1, wherein the length of the anchor rod is judged according to the loose degree of the soil property of the on-site slope, and the length meeting the on-site anchoring requirement is determined through a drawing test.
4. The method for constructing a river bank slope multiple ecological anchor pad protection as claimed in claim 1, wherein during the construction of the anchor rod member, the anchor rod is driven into the gap of the surface plant protection pad.
5. The river bank slope multiple ecological anchor pad protection construction method as claimed in claim 1, wherein the construction time is selected to be suitable for working in months with the average monthly temperature of 10-15 ℃.
