Column type inspection pit cast-in-place concrete track stand column and construction method
The invention provides a column type inspection pit cast-in-place concrete track stand column and a construction method. The column type inspection pit cast-in-place concrete track stand column comprises a full-hardened cushion layer, a base drainage ditch adopts an integrated all-steel formwork, and a shaped ladder stand is adopted; prefabricating a tubular pile cap rapid formwork system; the cast-in-place concrete track stand column formwork system is a unit type fast dismounting and mounting diagonal bracing steel pipe connecting and fixing type steel formwork system, and cast-in-place concrete track stand column concrete pouring is conducted through a winch traction rail-mounted material conveying pouring system. The construction method comprises the main construction steps of (1) surveying and setting out, (2) cushion layer cutting and crushing, (3) earth excavation, (4) foundation drainage ditch construction, (5) foundation cushion layer construction, (6) tubular pile cap construction, (7) raft foundation construction, (8) track column construction and (9) column bottom drainage ditch construction. According to the invention, the engineering cost can be effectively reduced, construction can be carried out by a centralized prefabrication and field assembly method, the construction speed is accelerated, and better technical and economic benefits can be obtained when the method is applied to actual engineering.
本发明提供一种柱式检查坑现浇混凝土轨道立柱及施工方法，包括全硬化垫层，基底排水沟采用一体式全钢模板，采用定型化爬梯；预制管桩桩帽快速支模体系；现浇混凝土轨道立柱模板体系采用单元式快速拆装对撑钢管联接加固定型钢模板体系，现浇混凝土轨道立柱混凝土浇筑采用卷扬机牵引轨行式运料浇筑系统；其主要施工步骤包括：(1)测量放线，(2)垫层切割破碎，(3)土方开挖，(4)基底排水沟施工，(5)基础垫层施工，(6)管桩桩帽施工，(7)筏板基础施工，(8)轨道柱施工，(9)柱底排水沟施工；本发明能有效降低工程成本，可实现集中预制、现场装配方法进行施工，加快了施工速度，应用于实际工程中可取得较好的技术经济效益。
