[0001] The present invention relates to the technical field of rail transit construction, and particularly to a tunnel secondary lining trolley for reserving a hole at the opening of a transverse passage. Background Art

[0002] During the construction of a subway mined station, the tunnel on the platform layer is usually connected to the left and right line tunnels through multiple transverse passages. During the tunnel excavation process, the secondary lining must be completed before entering the transverse passage for excavation. When the secondary lining of the main line is constructed, when the secondary lining trolley passes through the position of the transverse passage, due to the large-section horsehead portal to be reserved in the transverse passage, most construction methods are to use formwork supports and cooperate with small steel forms for secondary lining construction at the junction of the main line and the transverse passage. The construction efficiency is low, the appearance quality of the tunnel forming is poor compared with the trolley, and the process conversion is cumbersome. Therefore, exploring the construction technology for reserving the portal of the transverse passage during the secondary lining construction of large-section tunnels is particularly important for the rapid and safe construction of the secondary lining of large-section tunnels.

[0007] Further, the shaped template for the transverse passage portal is vertically welded to one side of the connecting edge, and the width of the shaped template for the transverse passage portal is equal to the thickness of the secondary lining wall.

[0008] Further, the fixed-form template for the transverse passage portal includes a transverse passage portal ring beam template, a left transverse passage portal side template, a right transverse passage portal side template, and a transverse passage portal bottom template.

[0010] The second technical solution provided by the present invention is as follows: A construction method for a tunnel secondary lining trolley with a reserved transverse passage opening hole includes the following steps: Step 1: Customize the fixed-form template for the transverse passage portal and the connecting plate according to the shape and size of the transverse passage portal; Step 2: Provide second bolt holes on the connecting plate, and then vertically weld the fixed-form template for the transverse passage portal and the connecting plate; Step 3: After the reinforcement bars of the secondary lining of the main line tunnel are tied up, move the secondary lining trolley to the inside of the reinforcement bars, check and verify the positioning clearance section of the secondary lining trolley, reinforce the secondary lining trolley, open the manhole on the side wall of the panel of the secondary lining trolley, and the operator enters the outside of the secondary lining trolley through the manhole to install the fixed-shaped formwork for the cross-passage portal. After the installation of the fixed-shaped formwork for the cross-passage portal is completed, the operator exits the working face through the manhole reserved on the secondary lining trolley.

[0013] Furthermore, in Step 3, during the installation of the fixed-shaped formwork for the cross-passage portal, first align the second bolt holes on the other side of the ring beam connection plate with the corresponding first bolt holes on the panel of the secondary lining trolley, and then fix the ring beam connection plate to the panel of the secondary lining trolley by passing high-strength bolts through the first bolt holes and the second bolt holes.

[0021] A tunnel secondary lining trolley for reserving holes of a transverse passage opening, as Figures 1 to 3 shown, includes a secondary lining trolley panel 1, a shaped template 2 for the transverse passage portal, and a connecting plate 3. The shaped template 2 for the transverse passage portal is fixed on the secondary lining trolley panel 1 through the connecting plate 3.

[0022] The present invention is applicable to the construction conditions of connecting the left and right line tunnels by multiple transverse passages in large-section tunnels. During the secondary lining construction of large-section tunnels, due to the need to reserve a large-section portal at the transverse passage portal, it is impossible to use a secondary lining trolley for secondary lining construction. Usually, a disc buckle formwork combined with small steel formwork is used for secondary lining construction. The workload of formwork erection and small steel formwork assembly is relatively large, and the space for personnel to install small steel formwork is narrow, resulting in great construction difficulty. In the present invention, during the secondary lining construction of the tunnel by using a secondary lining trolley with a fixed shaped template for the transverse passage portal, there is no need for the procedures of formwork erection and small steel formwork assembly. During construction, only the shaped template for the transverse passage portal needs to be fixed at the position of the transverse passage portal to reserve the hole of the transverse passage portal. It realizes that the secondary lining trolley can continuously operate when encountering a large-section reserved arc-shaped hole, improving the use efficiency and construction efficiency of the secondary lining trolley.

[0023] Furthermore, as Figures 1 to 3 shown, the shaped template 2 for the transverse passage portal is vertically fixed on one side of the connecting plate 3. The secondary lining trolley panel 1 is provided with a plurality of first bolt holes, and the plurality of first bolt holes are arranged at intervals on the secondary lining trolley panel 1 in the shape of the shaped template for the transverse passage portal. The other side of the connecting plate 3 is provided with second bolt holes at positions corresponding to the first bolt holes on the secondary lining trolley panel 1. The other side of the connecting plate 3 and the secondary lining trolley panel are fixedly connected by high-strength bolts 4 passing through the first bolt holes and the second bolt holes. To realize the connection between the connecting plate 3 and the secondary lining trolley panel 1, second bolt holes 5 and first bolt holes are provided at corresponding positions on the connecting plate 3 and the secondary lining trolley panel 1. Then, the connecting plate 3 is attached to the secondary lining trolley panel 1 and fixedly connected by high-strength bolts 4 passing through the first bolt holes and the second bolt holes 5. The shaped template 2 for the transverse passage portal is vertically fixed on one side of the connecting plate 3.

[0024] Furthermore, as Figures 1 to 3As shown, both the second bolt hole and the second bolt hole 5 are φ22 bolt holes. The hole pitch between the first bolt holes is 5°, and the hole pitch between the second bolt holes 5 is 5°. The high-strength bolt 4 is a 20 high-strength bolt. In this embodiment, both the first bolt hole and the second bolt hole 5 are φ22 bolt holes, and their positions correspond to each other. Therefore, the hole pitch between the first bolt holes is 5°, the hole pitch between the second bolt holes is also 5°, and the high-strength bolt 4 is a 20 high-strength bolt.

[0025] Furthermore, as Figures 1 to 3 shown, the fixed-form template 2 for the transverse channel portal is vertically welded to one side of the connecting plate 3, and the width of the fixed-form template 2 for the transverse channel portal is equal to the thickness of the secondary lining wall of the tunnel. The fixed-form template 2 for the transverse channel portal is vertically fixed to one side of the connecting plate 3 by welding. The positional relationship between the fixed-form template 2 for the transverse channel portal and the connecting plate 3 is vertical, and the width of the fixed-form template 2 for the transverse channel portal is equal to the thickness of the secondary lining wall of the tunnel. In this way, when the secondary lining trolley pours the secondary lining wall, it blocks the concrete from pouring to the position of the transverse channel portal, leaving the transverse channel portal reserved.

[0026] Furthermore, as Figures 1 to 3 shown, the fixed-form template 2 for the transverse channel portal includes a ring beam template for the transverse channel portal, a left side template for the transverse channel portal, a right side template for the transverse channel portal, and a bottom template for the transverse channel portal. The two ends of the ring beam template for the transverse channel portal are respectively connected to the upper ends of the left side template for the transverse channel portal and the right side template for the transverse channel portal. The lower end of the left side template for the transverse channel portal is connected to one end of the bottom template for the transverse channel portal, and the lower end of the right side template for the transverse channel portal is connected to the other end of the bottom template for the transverse channel portal to form the fixed-form template 2 for the transverse channel portal. The connecting plate 3 includes a ring beam connecting plate 31, a left side connecting plate 32, a right side connecting plate 33, and a bottom connecting plate 34. The ring beam template for the transverse channel portal is vertically welded to one side of the ring beam connecting plate 31, the left side template for the transverse channel portal is vertically welded to one side of the left side connecting edge 32, the right side template for the transverse channel portal is vertically welded to one side of the right side connecting plate 33, and the bottom template for the transverse channel portal is vertically welded to one side of the bottom connecting plate 34. In this embodiment, the structure of the fixed-form template 2 for the transverse channel portal and the structure of the connecting plate 3 are further implemented. The fixed-form template 2 for the transverse channel portal is formed by splicing the ring beam template for the transverse channel portal, the left side template for the transverse channel portal, the right side template for the transverse channel portal, and the bottom template for the transverse channel portal. The connecting plate 3 is formed by splicing the ring beam connecting plate 31, the left side connecting plate 32, the right side connecting plate 33, and the bottom connecting plate 34.

[0027] Furthermore, as Figures 1 to 3As shown, on the other side of the ring beam connecting plate 31, a second bolt hole 5 corresponding to the position of the first bolt hole is provided. On the other side of the left side connecting plate 32, a second bolt hole 5 corresponding to the position of the first bolt hole is provided. On the other side of the right side connecting plate 33, a second bolt hole 5 corresponding to the position of the first bolt hole is provided. On the other side of the bottom connecting plate 34, a second bolt hole 5 corresponding to the position of the first bolt hole is provided. The other side of the ring beam connecting plate 31 is fixed to the secondary lining trolley panel 1 by high-strength bolts passing through the first bolt hole and the second bolt hole 5. The other side of the left side connecting plate 32 is fixed to the secondary lining trolley panel 1 by high-strength bolts passing through the first bolt hole and the second bolt hole 5. The other side of the right side connecting plate 33 is fixed to the secondary lining trolley panel 1 by high-strength bolts passing through the first bolt hole and the second bolt hole. The other side of the bottom connecting plate 34 is fixed to the secondary lining trolley panel 1 by high-strength bolts passing through the first bolt hole and the second bolt hole 5. The ring beam connection 31, the left side connecting plate 32, the right side connecting plate 33 and the bottom connecting plate 34 are spliced on the secondary lining trolley panel into the shape of a fixed template for the transverse channel portal. Further, in the connecting plate 3, the beam connecting plate 31, the left side connecting plate 32, the right side connecting plate 33 and the bottom connecting plate 34 are fixed to the secondary lining trolley panel 1 by high-strength bolts 4 passing through the first bolt hole and the second bolt hole 5. The ring beam connection 31, the left side connecting plate 32, the right side connecting plate 33 and the bottom connecting plate 34 are spliced on the secondary lining trolley panel into the shape of a fixed template for the transverse channel portal.

[0028] The present invention also discloses a construction method for a secondary lining trolley of a tunnel with a reserved hole for a transverse channel opening, including the following steps: Step 1: Customize a fixed template for the transverse channel portal and a connecting plate according to the shape and size of the transverse channel portal; Step 2: Set second bolt holes on the connecting plate, and then vertically weld the fixed template for the transverse channel portal and the connecting plate; Step 3: After the secondary lining steel bars of the main line tunnel are tied, move the secondary lining trolley to the inside of the steel bars, check the positioning clearance section of the secondary lining trolley, reinforce the secondary lining trolley, open the manhole on the side wall of the secondary lining trolley panel, and the operator enters the outside of the secondary lining trolley through the manhole to install the fixed template for the transverse channel portal. After the installation of the fixed template for the transverse channel portal is completed, the operator exits the working surface through the manhole reserved on the secondary lining trolley, checks whether the reinforcement measures of the secondary lining trolley are in place, and then conducts secondary lining concrete pouring.

[0029] Further, in step 1, use 8mm steel plates to customize the ring beam template for the transverse channel portal, the left side template of the transverse channel portal, the right side template of the transverse channel portal and the bottom template of the transverse channel portal, and at the same time use 8mm steel plates to customize the ring beam connecting plate 31, the left side connecting plate 32, the right side connecting plate 33 and the bottom connecting plate 34.

[0030] Further, in step 2, a plurality of φ22 second bolt holes are opened on the other side of the ring beam connecting plate, the other side of the left side connecting plate, the other side of the right side connecting plate, and the other side of the bottom connecting plate.
