Example Embodiment

[0038] Example of tunnel lining trolley

[0039] see Figure 5 and Image 6 , in the coordinate system in the figure, the x-axis direction is the longitudinal direction of the tunnel, the z-axis direction is the height direction and the second direction of the present invention, and the y-axis direction is the transverse direction of the tunnel.

[0040] see Figure 5 , the tunnel lining trolley of the present invention includes a main frame body 11 and a plurality of poured lining overlapping devices 2 of the present invention that are telescopically connected to the main frame body 11 along the tunnel's circumferential direction. The lower part of the main frame body 11 is provided with a vertical jacking hydraulic cylinder 121 , and the main frame body 11 and the poured lining overlapping device 2 are connected by a jacking hydraulic cylinder 122 . In addition, the middle part of the main frame body 11 is also provided with an operation platform 13 and a ventilation pipe...

Abstract

The invention provides a poured lining lap joint device, a tunnel lining trolley and a tunnel construction method. The poured lining lap joint device comprises a back shore panel, a first lap joint extension piece, a first deformation piece, a second lap joint extension piece, a second deformation piece and a limiting piece, the back shore panel, the first lap joint extension piece, the second lap joint extension piece and the limiting piece are sequentially arranged in the longitudinal direction, the first deformation piece is arranged on the first lap joint extension piece, and the second deformation piece is arranged on the second lap joint extension piece. The second deformation piece is arranged on the second lap joint extension piece, the second deformation piece protrudes out of the first deformation piece, and the elastic deformation capacity of the second deformation piece is better than that of the first deformation piece. The tunnel lining trolley comprises a main frame body and a poured lining lap joint device connected to the main frame body. The tunnel construction method comprises the steps that pressure detection data of the first deformation part are obtained through the pressure sensing device; and when the pressure detection data reaches a preset value, the poured lining lap joint device stops stretching. The quality of the lining section and the quality of the lap joint construction seam of the lining section are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a poured lining overlapping device, a tunnel lining trolley and a tunnel construction method. Background technique [0002] When the secondary lining layer is poured in the tunnel construction, the existing construction technology uses the secondary lining trolley to carry out the cast-in-place concrete. The lining trolley has a rigid structure as a whole. When the car is pushed in place to position the formwork of the section to be poured and support it, it involves the overlapping operation of the side panel and the end of the poured lining section. [0003] The existing methods of lapping the ends of lining trolleys mainly include rigid lapping and flexible lapping. [0004] Such as figure 1 As shown, the poured first secondary lining section 91 is located in the first area 901 of the lining position 900, and the second area 902 is the area where the second secon...
