Abstract

The invention relates to a vertical loading device for duct pieces of different sizes in a counter-force well. The vertical loading device comprises a counter-force groove, a vertical loading stand column, a vertical loading cross beam, a vertical loading oil cylinder and an oil cylinder hanging plate. The counter-force groove is connected with the bottom end of the vertical loading stand column through a ground groove nut; the upper part of the vertical loading stand column is inserted into the vertical loading cross beam and is fixed through a compression nut; and the oil cylinder hanging plate connected with the vertical loading oil cylinder is connected with the vertical loading cross beam through nesting. The device has the advantages that the device is composed of the vertical loading stand column, the nut, the vertical loading cross beam, the vertical loading oil cylinder and the oil cylinder hanging plate, the vertical loading stand column is fixed to the counter-force groove,the vertical loading oil cylinder is hung below the vertical loading cross beam through the oil cylinder hanging plate; the structure is simple and operation is convenient; the vertical loading oil cylinder is hung below the height-adjustable vertical loading cross beam through the oil cylinder hanging plate, and the position of the vertical loading oil cylinder can be adjusted at will to adapt toduct pieces of different sizes.

Description

technical field [0001] The invention belongs to the technical field of underground tunnel engineering in engineering construction, and particularly relates to a vertical loading device and test method for segments of different sizes in a reaction well, and is especially suitable for vertical loading projects of segments of different sizes. Background technique [0002] China is in the era of great development of urban rail transit, and every city is constantly building and improving its own rail transit. In recent years, with the continuous expansion and development of medium and large cities, urban ground transportation can no longer fully meet people's needs for urban travel, which forces people to turn their attention to underground space and urban subways. At present, shield tunneling has been favored by more and more cities due to its advantages of underground excavation and no weather restrictions, and has become the main structural form of municipal infrastructure suc...
