Pipe jacking well enclosure structure and excavation construction method
The invention provides a pipe jacking well enclosure structure and an excavating and supporting method thereof, and belongs to the field of pipe jacking construction. According to the technical scheme, the excavating and supporting method for the pipe-jacking well enclosure structure comprises the following steps of field leveling, dewatering well construction, steel sheet pile construction, first-layer earth excavation, concrete ring beam construction, subsequent section construction and bottom sealing. The pipe jacking well enclosure structure and the excavating and supporting method thereof have the beneficial effects that the construction period is short, turnover use is achieved, the manufacturing cost is low, the supporting strength is high, the underground space is sufficient, safety is high, construction safety and construction efficiency are improved, and besides, environment protection is facilitated.
本发明提供了一种顶管井围护结构及其开挖支护方法，属于顶管施工领域。其技术方案为：所述顶管井围护结构开挖支护方法包括以下步骤：平整场地、降水井施工、钢板桩施工、第一层土方开挖、混凝土圈梁施工、后续节段施工及封底。本发明的有益效果为：本施工方法施工周期短、可周转使用、造价低、支护强度较高、地下空间充足、安全性高，提高了施工安全和施工效率，同时利于保护环境。
