Construction method for excavation slope retaining wall reversed filter layer
The invention discloses a construction method for an excavation slope retaining wall reversed filter layer. The construction method includes the steps that a slope surface is vibrated and compacted after the slope surface is excavated and formed; short anchor rods are stricken into a slope body with ends of a certain length reserved outside the slope surface; a layer of high-strength water insulation film is laid and fixed to the ends of the short anchor rods; the space between the high-strength water insulation film and a slope surface rock-soil body is filled with a compact sand gravel reversed filter layer; after the high-strength water insulation film is fixed to the slope surface through the short anchor rods, the space between the high-strength water insulation film and the rock-soil body is filled with the sand gravel reversed filter layer, and the sand gravel reversed filter layer is vibrated and compacted; then, a retaining wall is constructed. After the sand gravel reversed filter layer is vibrated and compacted, the high-strength water insulation film can form a smooth outer surface with certain rigidity and can play the role of an inner formwork when the retaining wall is constructed, and therefore a behind-wall formwork in the conventional retaining wall construction process can be replaced; the procedure of detaching the inner formwork is not needed after the retaining wall construction is completed; the construction process is greatly simplified; the construction quality of the reversed filter layer behind the retaining wall can be easily ensured; and the construction quality of the retaining wall and the reliability of retaining engineering are effectively improved.
