Immersed tube tunnel reinforcing system penetrating through breakwater downwards and construction method of immersed tube tunnel reinforcing system
The invention relates to the technical field of immersed tube tunnels, and discloses an immersed tube tunnel reinforcing system penetrating through a breakwater downwards and a construction method of the immersed tube tunnel reinforcing system. The reinforcing system comprises a first foundation trench, a second foundation trench, prestressed high-strength concrete pipe piles, an underground diaphragm wall foundation, high-pressure jet grouting piles, a cushion layer, an immersed tunnel, a steel shell reinforced concrete force transmission system, a breakwater foundation, a breakwater reinforcing layer and a rebuilding breakwater. The breakwater foundation is arranged on the upper portion of the top end of the steel shell reinforced concrete force transfer system, the breakwater reinforcing layer is arranged on the side face of the rebuilt breakwater, and the breakwater reinforcing layer and the rebuilt breakwater are arranged on the breakwater foundation. Therefore, on the basis that the original breakwater function is not damaged, the influence of the upper breakwater load and the external additional load on the immersed tube tunnel can be reduced, the problem of uneven settlement of the foundation caused by uneven overlying load is solved, the internal force and deformation of the immersed tube tunnel are reduced, and the effect of protecting the immersed tube tunnel is achieved.
本发明涉及沉管隧道技术领域，公开了一种下穿防波堤的沉管隧道加固体系及其施工方法，其中，加固体系包括：第一基槽、第二基槽、预应力高强度混凝土管桩、地下连续墙基础、高压旋喷桩、垫层、沉管隧道、钢壳钢筋混凝土传力体系、防波堤基础、防波堤加固层以及复修防波堤，沉管隧道设置在垫层之上，防波堤基础设置在钢壳钢筋混凝土传力体系顶端上部，防波堤加固层设置在复修防波堤侧面，防波堤加固层以及复修防波堤设置在防波堤基础之上。由此，本发明在不破坏原有防波堤功能的基础上，能够减小上部防波堤荷载及外部附加荷载对于沉管隧道的影响，减少不均匀上覆荷载引发的地基不均匀沉降的问题，降低沉管隧道内力与变形，具有保护沉管隧道的作用。
