The invention discloses a supporting device for subway construction. The supporting device comprises a pre-buried sliding groove pre-buried in a shield wall; the arc-shaped plate is attached to the shield wall; the arc-shaped plate is connected to the embedded sliding groove through the connecting piece; the supporting plates are welded to the two ends of the arc-shaped plate; and the bottom plate is used for supporting and is horizontally arranged. The embedded sliding grooves do not damage an existing structure of a shield wall, safety guarantee of a tunnel structure is further improved, the construction environment in a tunnel hole is improved, the positions of the connecting pieces can be adjusted in the embedded sliding grooves, it is guaranteed that the bottom plate is horizontally placed by adjusting the positions of the arc-shaped plates, and the gantry crane stably runs on the walking rail. The position of the connecting piece is fixed through the first thread teeth and the second thread teeth, the friction force in the tangential direction along the shield wall is increased, and therefore enough supporting force can be provided. The static force level gauges on the base are mutually connected to form a monitoring and early warning system, problems are found and processed in the first time after monitoring and early warning occur, and safety during subway construction and operation is guaranteed.

    一种地铁施工用支撑装置,包括:预埋于盾构壁内部的预埋滑槽;贴合于盾构壁的弧形板;将弧形板连接于预埋滑槽上的连接件;焊接于弧形板两端的支撑板;以及用于支撑的底板,底板为水平设置。预埋滑槽不会破坏盾构壁的现有结构,对隧道结构的安全保障进一步提升,改善了隧道洞内的施工环境,连接件可在预埋滑槽内调整位置,通过对弧形板的位置调整保证底板水平放置,使龙门吊在走行轨上平稳运行。第一螺纹牙和第二螺纹牙固定了连接件的位置,增加了沿盾构壁延切线方向的摩擦力,从而可以提供足够的支撑力。底座上的静力水准仪相互连接形成监测预警系统,出现监测预警后第一时间发现问题并进行处理,保障地铁施工时和运营时的安全。
