Construction method of ultra-long large-size bearing platform for large aircraft test
The invention discloses a construction method of a super-long large-size bearing platform for a large aircraft test, and the bearing platform is cast in a mold splitting manner, and comprises the following steps: S1, casting a foundation pile; s2, surveying and setting out are conducted, a foundation pit is excavated, the pile head of a foundation pile is treated, and then a cushion layer is poured; s3, a formwork is erected, reinforcing steel bars are bound, concrete pouring is conducted on a first layer of bearing platform, C30 micro-expansion compensation type concrete is adopted within the range of 1 m of the end of the bearing platform, 10% of expanding agents are added, cooling pipes and temperature measuring elements are embedded, maintenance is conducted, and foundation pit backfilling is conducted; and S4, measuring and lofting again, chiseling the surface of the first-layer bearing platform concrete, brushing a cement grout interface agent, erecting a formwork, binding reinforcing steel bars, installing a high-strength reinforced net, pouring second-layer bearing platform concrete, adopting compensatory concrete, adding 16% of an expanding agent, embedding a cooling pipe and a temperature measuring element in the concrete, and maintaining. The device has the advantages of stable structure and high strength.
本发明公开了一种用于大飞机试验的超长大体积承台的施工方法，所述承台分模浇筑，包括以下步骤：S1：浇筑基础桩；S2：测量放样，开挖基坑，对基础桩桩头进行处理，然后浇筑垫层；S3：立模板，绑扎钢筋，进行第一层承台混凝土浇筑，承台端头1m范围内采用C30微膨胀补偿型性凝土，加10％膨胀剂，埋设冷却管及测温元件，进行养护、基坑回填；S4：再次测量放样，在第一层承台混凝土表面凿毛，涂刷水泥浆液界面剂，立模板、绑扎钢筋，安装高强加筋网、进行第二层承台混凝土浇筑，采用补偿性混凝土，加16％膨胀剂，中埋设冷却管及测温元件，进行养护。具有结构稳定，强度高的优点。
