Embodiment Construction
[0020] The principle of the terminal template design is as follows Figure 1-Figure 6 As shown, the standard block 1 is provided with a positioning slideway 4, the length and width of the standard block 1 can be adjusted according to the thickness of the secondary lining of the tunnel, the positioning slideway 4 is connected with a suspension rod, and the suspension rod 5 can fix the standard block , the fixed bolt 3 is composed of a hydraulic jack 7, a pressure-bearing steel plate 8 and a push rod 6. There are multiple hydraulic jacks 7, and every two hydraulic jacks 7 are connected by a pressure-bearing steel plate 8, wherein the pressure-bearing steel plate 8 The length can be determined according to the bearing pressure, and then determine the quantity of hydraulic jack 7. The gap between the pressure-bearing steel plate 8 and the secondary lining end steel plate 9 can be controlled by the movement of the piston rod of the hydraulic jack 7 . The suspension rod 5 is connec...

The invention provides an end die plate of a tunnel secondary lining trolley. The end die plate comprises standard blocks, an adjustment block, an end steel plate, a secondary trolley inner film and a fixing bolt. The end steel plate is composed of two vertical plates, one face of the secondary trolley inner film is connected to one outer side face of the end steel plate, and the other outer side face of the end steel plate is connected with the standard blocks. A water stop is arranged on the opposite face of the other face of the secondary trolley inner film and connected to the ends of the standard blocks, and the space between the secondary trolley inner film and the water stop is filled with concrete used for secondary lining. The end die plate of the tunnel secondary lining trolley is practical and convenient and rapid to use, reduces wood consumption and labor intensity of workers, improves working efficiency and is convenient to popularize, use, assemble and disassemble.
Description
technical field [0001] The invention relates to a formwork for the end of a trolley for secondary lining of a tunnel, and belongs to the technical field of tunnel engineering. Background technique [0002] When performing the secondary lining of the tunnel in the expressway tunnel, the secondary lining trolley is usually used as the inner mold, and the wooden board is used as the end formwork. The secondary lining trolley is usually customized by the construction unit in the manufacturer according to the design drawing of the inner contour of the tunnel, and the end formwork is fixed by the on-site construction personnel through the cut wooden boards through the welded steel pipes on the secondary lining trolley. The radius of the inner contour of the secondary lining of the two-lane tunnel is about 5.5m, and the circumference above the arch line is about 17m. The boards with a width of 30cm are used as the end formwork, and about 60 pieces are needed. Using wooden boards a...
