Construction method for permanent steel pipe structural column of covered and excavated station
The invention discloses a construction method for a permanent steel pipe structural column of a covered and excavated station, and relates to the technical field of construction of the permanent steel pipe structural column of the covered and excavated station. The construction method at least comprises the following steps that surveying and setting out are conducted for the first time, after a pile machine is in place, road breaking is conducted through the pile machine, a pile casing and a foundation pile are buried, the buried pile casing is measured and rechecked, and foundation pile construction filling is formed. The steel pipe column in the construction method is a steel pipe column formed through one-time construction and used as a later-stage structural column, the tool column is adopted for connection and then inserted into the position of the main body structural column, the tool column is cut off after insertion is completed, the construction difficulty of in-station cutting off of a traditional latticed column is avoided, the construction process is simplified, and the construction efficiency is improved. And in the construction method, the cast-in-situ bored piles are adopted and 36-hour super-retarding concrete is adopted, so that sufficient construction time is reserved for pipe insertion construction of the steel pipe column, and the construction progress is guaranteed.
本发明公开了盖挖车站永久钢管结构柱施工工法，涉及盖挖车站永久钢管结构柱施工技术领域。本发明至少包括以下步骤：第一次测量放线，在桩机就位后，采用桩机破路，并埋放护筒和基础桩，对埋放好的护筒进行测量复核，形成基础桩施工填。本发明在施工工法中的钢管柱为一次施工成型钢管柱，作为后期结构柱使用，采用一根工具柱连接后插入到主体结构柱的位置，插入完成后将工具柱进行割除，避免了传统格构柱站内割除的施工困难，简化了施工过程,且在施工工法中采用钻孔灌注桩采用36h超缓凝混凝土，为钢管柱插管施工预留了充足的施工时间，但又保证了施工进度。
