Construction method for firstly constructing pipe jacking riding well
The invention discloses a construction method for firstly constructing a jacking pipe riding well. The construction method comprises the steps of site leveling, surveying, setting out and positioning, steel casing machining, alternate construction of steel casing sinking and earth excavation, underwater concrete bottom sealing in the well, hole compaction and grouting, guide rail installation in the well, hole breaking, hole receiving and starting and hole plugging. The method has the advantages that the applicability is high, the construction speed is high, the riding well can be constructed in a narrow area, disturbance to surrounding soil is small, use is safe and reliable, the construction cost is reduced, and the construction speed is high.
本发明公开了一种先施工顶管骑马井的施工方法，包括场地平整、测量放线定位、钢护筒加工、钢护筒下沉和土方开挖交替施工、井内水下砼封底、洞口压密注浆、井内导轨安装、洞口破除、洞口接收和始发、洞口封堵步骤。该方法具有适用性高，施工速度快、可在狭小区域施工骑马井，对周边土体扰动小，使用安全可靠，降低施工成本，施工速度快的优点。
