A late poured band construction method of basement soleplate belongs to the technical field of building construction, and is characterized in that a plain concrete cushion is poured and extended below a late poured band, a reinforced cushion as well as corresponding drainage ditches and dilatation joints are poured and installed above the plain concrete cushion; after the reinforcing steel bars of basement soleplate are finished to be bundled, one side of the late poured band is supported and poured with concrete, and the other side of the same basement soleplate is poured with concrete; the late poured band is cleaned and is poured with concrete so as to finally be sealed. The late poured band construction method of basement soleplate greatly reduces the operation capacity of chiseling off loosened concrete at both sides of the late poured band, thereby favourably guaranteeing the reliable connection between the basement soleplate and the reinforcing bar cushion, avoiding gaps between the basement soleplate and the reinforcing bar cushion due to shrinkage, effectively preventing groundwater from entering before the late poured band is sealed, and keeping dryness inside the basement; otherwise, the reinforcing steel bars under the basement soleplate are avoided to be buried by cement paste or sundries, thereby reducing the labor cleaning strength, and greatly improving the construction quality of late poured band.

The invention discloses a self-elevation sand retaining plate which comprises a blown sand retaining plate and a base. The front end of the base is connected with the blown sand retaining plate. The rear end of the base is hinged with a pillar fixed on the foundation. The hinge joint between the base and the pillar is more than 10 meters above the ground.
