Civil engineering foundation formwork construction process and fixing device thereof

The invention belongs to the field of civil engineering base formworks, and particularly relates to a civil engineering base formwork construction technology and a fixing device thereof.The technology specifically comprises the steps that S1, a mold for base formwork shaping is taken out, then side plates of the mold are placed on the ground in sequence, then all the side plates of the mold are vertically placed, and a space with the periphery sealed is defined by the middles of the side plates; s2, a plurality of side plates are fixed in a surrounding mode through a fixing device, after fixing is completed, concrete is poured into the mold from the top end of the mold to the center, and after the concrete is solidified, the fixing device and the side plates are dismantled, and a shaped concrete base mold can be obtained; by means of the arrangement, in the occasion that the mold is long, a traditional fixing device does not need to be manually used, the mold is fixed on the outer side of the mold at interval
