Technical Field

[0001] The invention relates to the technical field of tunnel lining construction, in particular to a tunnel lining trolley. Background Art

[0002] Tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the concrete lining construction of the inner wall of the tunnel. Tunnel lining trolley is an indispensable non-standard product for the secondary lining of the tunnel construction process. It mainly includes simple lining trolley, fully hydraulic automatic walking lining trolley and grid lining trolley.

[0003] At present, the number of newly built expressways in mountainous areas is increasing, and the number of extra-long tunnels is increasing. Often, during the construction of tunnels, especially in the construction of long and large tunnels, the cross-section changes a lot. In the existing technology, the vent elevation section is assembled by "steel profile + small flat mold" for concrete pouring. However, the "steel profile + small flat mold" assembly method takes too long to manually splice, which reduces the construction efficiency and the safety factor of the construction. Summary of the invention

[0004] The purpose of the present invention is to provide a tunnel lining trolley to alleviate the technical problems existing in the prior art of "steel section + small flat mold" assembly method, that is, the manual splicing time is too long, the construction efficiency is reduced, and the safety factor of the construction is reduced.

[0006] Furthermore, the tunnel lining trolley also includes a plurality of columns; a plurality of first grooves cooperating with the columns and a plurality of second grooves cooperating with the columns are respectively provided on the elevated section template and the top template; the plurality of columns are arranged between the elevated section template and the top template, and the plurality of columns are used to limit the relative movement between the elevated section template and the top template.

[0007] Furthermore, the elevated section template includes a plurality of sub-molds; the plurality of sub-molds are arranged at intervals along the extension direction of the top mold, and the side walls of two adjacent sub-molds are in contact with each other.

[0008] Furthermore, a panel is provided at each end of the elevated section template; the panel is fixedly connected to the elevated section template, and the panel is detachably fixedly connected to the top template.

[0009] Furthermore, the panel and the top mold are connected by bolts.

[0010] Furthermore, the panel is welded to the elevated section template.

[0011] Furthermore, a pouring port for pouring concrete is provided on the elevated section template.

[0012] Furthermore, the tunnel lining trolley also includes a gantry system, a hydraulic system and a traveling system; the fixed formwork cover is arranged on the outside of the gantry system; the hydraulic system is used to adjust the distance between the gantry system and the fixed formwork; the traveling system is arranged at the bottom of the gantry system, and the traveling system is used to drive the gantry system and the hydraulic system to move.

[0023] Figure 1 A front view of a tunnel lining trolley provided in an embodiment of the present invention; Figure 1 As shown, the tunnel lining trolley provided by the embodiment of the present invention includes: an elevated section template 1 and a fixed template 2; the fixed template 2 is arc-shaped; the elevated section template 1 is crescent-shaped, and the arc surface of the elevated section template 1 can fit the tunnel contour; the elevated section template 1 is buckled on the top template 3 of the fixed template 2, and the elevated section template 1 and the fixed template 2 are detachably fixedly connected.

[0024] During use of the tunnel lining trolley provided in the embodiment of the present invention, when the tunnel lining trolley travels to the elevated section, the elevated section template 1 is buckled on the top template 3 and fixedly connected to the top template 3, so that the arc surface of the elevated section fits the contour of the tunnel, and then concrete is poured. When the elevated section is completed, the elevated section template 1 is removed from the top template 3 for next use.

[0025] As can be seen from the above, since the elevated section template 1 is crescent-shaped, it only needs to be buckled on the top template 3 during construction. Compared with the existing technology, this can save the assembly time of construction workers and improve the stability of the tunnel lining trolley; at the same time, since the safety risk factor of the assembly construction process is relatively high, reducing the assembly time also improves the safety of construction. In addition, since the elevated section template 1 is crescent-shaped and the curved surface can fit the tunnel contour, during the concrete lining construction, the tunnel lining trolley can better fit the tunnel contour, improve the lining construction effect, and ensure the appearance quality.
