In the step vi, in the water stopping seam construction process, the water stopping sheets are flat and clean and have no sand holes or nail holes, the connection of the water stopping sheets adopts a folding mode, a meshing mode or an overlapping mode according to the thickness of the water stopping sheets, the overlapping length of the water stopping sheets is not less than 20 millimeters, and the meshing and overlapping parts need to be welded in a double-sided mode. The rubber water stop sheet is installed to prevent deformation and tearing; the installed water stop should be reinforced and protected.
In the side slope deformation control process in the step vii, in order to ensure the stability of the assembled masonry framework side slope protection structure in the construction process and the rear side slope protection process, regular inspection and monitoring are required.
The slope surface reinforcing method effectively utilizes the raw stones to reinforce the slope surface, plays a role in gravity back pressure compared with a single lattice slope protection, can better utilize the raw stones, and reduces the waste slag of field excavation.
Compared with an integral slope protection structure, the invention adopts the assembled slope protection construction, and compared with mortar rubble, the invention can accelerate the construction and ensure the construction period.
The invention is suitable for the slope with certain frost heaviness, expansibility and other characteristics or the area where the slope may have certain repeated deformation, and can better adapt to the change of the deformation and the fluctuation of the slope and reduce the cracking of the slope protection structure.
