Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: although the first lifting mechanism and the second lifting mechanism can adjust the height of the frame body, so that the frame body is suitable for tunnel roof walls of different heights, the tunnel roof walls of different types of tunnels are The radians are also different, so that the first lifting mechanism and the second lifting mechanism cannot drive the frame body to be suitable for tunnels with different radians, which reduces the applicability of the tunnel support frame

Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] refer to figure 1 , is a subway tunnel construction support disclosed in the present invention, comprising a beam 1, the two ends of the beam 1 are perpendicular to the beam 1 are provided with support beams 11, and the ends of the support beams 11 on both sides away from the beam 1 are provided with support plates 111 .
[0035] combine figure 1 and figure 2 , in order to support the tunnel top wall with different radians, a plurality of supports for supporting to the inner wall of the tunnel are uniformly arranged on the surface of the beam 1 facing the inner wall of the tunnel, and each support includes a connecting plate 12 on which An abutment plate 121 for abutting against the top wall of the tunnel is provided, and each abutment plate 121 is arranged in an arc shape; The support of the top wall of the tunnel improves the applicability of th...

The invention relates to a subway tunnel construction support, which belongs to the technical field of tunnel construction facilities, and includes a crossbeam, the two ends of the crossbeam are provided with support beams, the ends of the support beams on both sides away from the crossbeam are provided with support plates, and the surface of the crossbeam facing the inner wall of the tunnel There are multiple supports evenly arranged on the top, each support includes a connecting plate, and an abutment plate is arranged on the connecting plate, and each abutting plate is arranged in an arc shape, and a connecting plate is provided on the connecting plate for driving the abutting plate to approach or move away from For the first driver of the tunnel top wall, a chute is opened on the surface of the crossbeam facing the tunnel top wall, and the connecting plate is provided with a slider that is slidably connected in the chute. The setting of multiple abutment plates can make each abutment The curvature of the plate becomes smaller, so that multiple abutment plates can be applied to tunnel roof walls with different curvatures; the first driving member can drive the abutment plate to move toward the tunnel roof wall, so that the abutment plate can be applied to tunnels of different heights The top wall improves the applicability of the entire tunnel construction support.
Description
technical field [0001] The invention relates to the technical field of tunnel construction facilities, in particular to a subway tunnel construction support. Background technique [0002] Tunnel support refers to the support structure set up to prevent deformation or collapse of surrounding rock during tunnel excavation. Commonly used are component support and shotcrete anchor support. Tunnel support plays a vital role in ensuring the safety and quality of tunnel construction in order to avoid serious deformation of the tunnel and even collapse. [0003] The Chinese patent application publication No. C110700871A discloses a tunnel support template for civil engineering, including a support plate, the support plate is fixedly connected to the support column, the support column is fixedly connected to the beam frame, and a base is arranged under the support plate. A first lifting mechanism is set between the board and the base; a frame body located above the beam frame is als...
