Anti-floating construction structure for river channel above tunnel and construction method of anti-floating construction structure
The invention relates to the technical field of building construction, in particular to an anti-floating construction structure and method for a river channel above a tunnel, and the construction structure comprises an uplift pile row, a reinforcing body and an anti-floating plate; a reinforcing body is arranged on a tunnel shield area soil body located in the planned river channel range, and an anti-floating plate is arranged on the reinforcing body; wherein the outer side lines of the reinforcing bodies located on the two sides of the tunnel shield area exceed the outer side line of the soil body of the tunnel shield area; the uplift pile rows comprise a plurality of uplift piles arranged at intervals, the uplift pile rows are arranged on the two sides of the tunnel and in the reinforcing body located between the two tunnel shield lines, and the uplift piles of the uplift pile rows are fixedly connected with the anti-floating plate. By means of the system of the anti-floating piles, the reinforcing bodies and the anti-floating plates, displacement or floating of the shield after river channel earth excavation unloading can be effectively prevented through the friction force of the anti-floating piles, the reinforcing effect of the reinforcing bodies and the anti-floating effect of the anti-floating plates.
本发明涉及建筑施工技术领域，尤其涉及一种隧道上方河道抗浮施工结构及其施工方法，该施工结构包括抗拔桩排、加固体和抗浮板；在位于规划河道范围内的隧道盾构区土体设置有加固体，且加固体上设置有抗浮板；其中，位于隧道盾构区两侧的加固体的外边线超出隧道盾构区土体的外边线；该抗拔桩排包括多个间隔布置的抗拔桩，该隧道的两侧及位于两个隧道盾构线之间的加固体内均设置有一抗拔桩排，且抗拔桩排的多个抗拔桩均与抗浮板固定连接。通过抗浮桩+加固体+抗浮板的体系，利用抗浮桩的摩擦力、加固体的加固作用以及抗浮板的抗浮作用能够有效的防止河道土方开挖卸载后盾构位移或上浮。
