Background

The combined type template trolley is mainly applied to secondary lining construction of a lower anchor section of a railway tunnel so as to accelerate construction progress and save construction cost. When the existing combined type formwork trolley is used for constructing the lower anchor section, if the existing combined type formwork trolley meets adverse factors such as gradient and the like on the ground, deformation is easy to occur in the jacking work. The structure of the existing combined type formwork trolley is shown in fig. 1-3, fig. 1 and 2 are respectively a schematic side structure diagram of the combined type formwork trolley along the length direction of a tunnel, fig. 1 is a schematic diagram of the formwork trolley when the formwork trolley is not lifted, and fig. 2 is a schematic diagram of the formwork trolley after being lifted. Because the formwork trolley only needs to lift the anchor section part with a section of length in the lifting work, two types of upright columns, namely a first upright column 11 and a second upright column 12, are designed; the first upright post 11 has a jacking function and can move along the vertical direction, and the second upright post 12 mainly plays a role in stabilizing; when jacking work is carried out in construction, the height of the first upright post 11 is adjusted, and the anchor section part 13 in the formwork trolley can be jacked to a preset position; after the jacking operation is completed, the anchor section part 13 in the form trolley 1 is higher than the normal section part, and the concrete jacking effect can be compared with the change situation of the anchor section part 13 in fig. 1 and fig. 2, wherein the first upright post 11 belongs to the anchor section part 13, and the second upright post 12 belongs to the normal section part. However, since the anchor segment 13 is not integrated with the normal segment in the formwork trolley, the stability of the anchor segment 13 is lowered during the lifting operation, leading to the forward inclination of the anchor segment 13 and the deformation of the formwork trolley 1.
