More Information
Summary:The invention relates to a construction method of a large-gradient underground passage profile steel gap drainage ditch. The construction method comprises the following steps: pre-burying symmetrical integral rib frame fixing profile steel for construction; profile steel gap type drainage ditches are installed; constructing a base of the inspection well; constructing an inspection well shaft; construction of a profile steel gap type drainage ditch inspection well fixing structure; and recovering pavement construction. The method has the beneficial effects that the profile steel gap type drainage ditch is effectively fixed through the symmetrical profile steel anti-corrosion steel bars on the two sides and the pre-buried symmetrical integral rib frame fixing profile steel; the stability of the prefabricated shaft is effectively guaranteed by arranging the anti-skid prefabricated base connected with the tongue-and-groove of the cushion layer and combining the symmetrical profile steel anti-corrosion steel bars
