The invention discloses a construction method for an ultra-large-area
pile bearing terrace of a whole vehicle
plant. Comprising the following steps of
pile group construction modeling analysis, stress release measures,
pipe pile construction, pile head treatment, pile core grouting construction, base layer treatment and
cushion layer construction, PE damp-proof layer construction,
pile cap construction, special structure junction construction, terrace
steel bar binding, armored seam installation, concrete pouring and tamping, elevation and flatness control, wear-resistant carborundum ground construction and flatness rechecking. According to the method, pile groups are adopted to effectively support the terrace, the influence caused by differential settlement of the terrace in the later period is avoided, the concrete mixing proportion is optimized, the abrasion resistance and
crack resistance of the terrace are enhanced, detail nodes are optimized for the positions prone to
cracking and the joints of the terrace and special structures, and the construction efficiency is improved. And through the methods of alternate bin pouring, short-distance stress release, reasonable construction organization and the like, the anti-
cracking requirement of the standard on the large-area terrace is met, and the construction period is greatly shortened.
