Winter outdoor apron construction method

Abstract

The invention discloses a winter outdoor apron construction method, and relates to the field of apron slope building construction. The method comprises the steps that hot-rolled ribbed steel bars are added after an apron foundation is tamped to form a bracket structure, the side face of a ground beam is chiseled, the bonding effect of concrete and the ground beam is improved, a bracket formwork is supported and poured, the bracket formwork is detached after 75% of strength is reached, the bracket lifting amount is small, and the supporting effect of the concrete formwork is improved; and backfilling, formwork supporting, pouring and heat preservation treatment are carried out on an apron area, the formwork is detached after the apron area is completely cured, and expansion joint construction is carried out. According to the method, the foundation cannot settle after a frozen soil layer is opened in summer during winter outdoor apron construction, the construction quality is guaranteed, and secondary repair construction is avoided.

Description

technical field [0001] The invention relates to the construction field of water-scattering slopes, in particular to an outdoor water-scattering construction method in winter. Background technique [0002] At present, under winter construction conditions, the soil layer construction cannot achieve the corresponding degree of compaction, and the schedule plan must be buckled, resulting in the inability of the outdoor bulk water project to be constructed under sufficient conditions. Due to the underground pre-buried, drainage pipes, sewage pipes, rainwater pipes, cable pipes, etc., the minimum depth reaches -900mm, and most of the underground pre-buried pipes are made of plastic materials such as PE pipes and UPVC pipes, which makes the foundation part unable to be compacted thoroughly. The natural settlement speed of the soil layer in winter is too slow, and the outdoor water scattered after the construction in winter cannot be effectively compacted by large-scale machinery, a...

Problems solved by technology

[0002] At present, under winter construction conditions, the soil layer construction cannot achieve the corresponding degree of compaction, and the schedule plan must be buckled, resulting in the outdoor bulk water project not being able to be constructed under sufficient conditions

Due to the underground pre-buried, drainage pipes, sewage pipes, rainwater pipes, cable pipes, etc., the minimum depth reaches -900mm, and most of the underground pre-buried pipes are made of plastic materials such as PE pipes and UPVC pipes, so the foundation cannot be completely compacted

The natural settlement speed of the soil layer in winter is too slow, and the outdoor water scattered after construction in winter cannot be effectively compacted by large-scale machinery, and the subsidence of the frozen soil layer in spring caused by insufficient compaction of the soil layer causes the outdoor water scattered to sink.
