[0042] Please refer to the attached document. Figures 1-4This application illustrates an intelligent lining trolley for a large cross-section underground railway station that can accommodate large TBMs passing through, specifically including: a double-layer trolley assembly, a lining platform assembly 5, a telescopic support 8, and a material trough structure 7.

[0043] The bottom of the first layer of the double-layer trolley assembly forms a passage for the TBM to pass through, meeting the TBM's movement needs during construction. The double-layer trolley assembly is a movable structure; after pouring a section, the structure attached to the inner side of the tunnel can be moved forward a certain distance to allow for the pouring of the second section, significantly improving the efficiency of lining pouring. The lining platform assembly 5 is attached to the inner side of the tunnel, and a telescopic support 8 is hinged to the inner side of the lining platform assembly 5. The end of the telescopic support 8 furthest from the lining platform assembly 5 is hinged to the outer side of the double-layer trolley assembly, allowing for telescopic movement. Support component 8 is a hydraulic expansion component / threaded expansion component, which is used to support the lining assembly 5, so that the lining assembly 5 and the inner side of the tunnel form a pouring interlayer (the interlayer needs to be tied with steel bars, and the construction process of tying steel bars can also rely on the double-layer trolley assembly, without the need to erect additional scaffolding). The material trough structure 7 is installed on the double-layer trolley assembly and is used to pour concrete at the working window of the lining assembly 5. The material trough structure 7 guides the concrete to the working window of the lining assembly 5, and from the working window of the lining assembly 5, it enters the pouring area between the lining assembly 5 and the inner side of the tunnel for pouring.

[0044] This utility model, through the design of a double-layer trolley assembly, forms a passage at the bottom of the first-layer platform 1 for the TBM to pass through the station, which can meet the needs of the TBM to move through the station during construction. Moreover, the double-layer trolley assembly is used to support the lining assembly 5, thereby enabling rapid pouring in the pouring area between the lining assembly 5 and the inner side of the tunnel. Compared with the traditional formwork structure, its construction efficiency is greatly improved and its construction safety is better.

[0045] In order to achieve efficient grouting, several sets of grouting components with molds are provided on the liner assembly 5.

[0046] Specifically, the double-layer trolley assembly includes: a first-layer trolley frame 1 and a second-layer trolley frame 2.

[0047] The first-level platform 1 includes several spaced-apart portal frames, which are fixedly connected by connecting frames to form a passage structure. The bottom of the first-level platform 1 is fixedly installed with a traveling component 4, which is driven by four 3kW synchronous motors and then drives the portal frames to move through a reducer and gear reduction. The second-level platform 2 is fixedly connected to the top of the first-level platform 1. The second-level platform 2 consists of columns, crossbars and longitudinal bars. The top of the second-level platform 2 is fixedly connected with an auxiliary platform 3, which consists of several platforms whose height matches the top of the tunnel.

[0048] In one embodiment, a ground support 4a is hinged to the walking component 4 on the inner side of the first-layer platform 1. The ground support 4a is a telescopic component and is used to stabilize the first-layer platform 1. When walking, the bottom of the ground support 4a needs to be separated from the ground.

[0049] In one embodiment, ladders 9 are installed on the first-floor platform 1, the second-floor platform 2, and the auxiliary platform 3 to allow construction personnel to go up and down the first-floor platform 1, the second-floor platform 2, and the auxiliary platform 3.

[0051] The top platform 501 has one set, and the first side platform 502, the second side platform 503, and the third side platform 504 each have two sets, and their unfolding forms are as follows: Figure 3 As shown, the top platform 501, the first side platform 502, the second side platform 503, and the third side platform 504 together form the shape of the inner side of the tunnel.

[0052] In one embodiment, a vibrator 6 is provided on the inner side of the lining assembly 5. The vibrator 6 is used to vibrate the concrete to make the concrete more compact.

[0053] Vibrators 6 are spaced apart on the roof platform 501 along the length of the tunnel, with two vibrators 6 installed on each roof platform 501. Figure 3 As shown, two vibrators 6 are installed on the top platform 501 that are spaced apart, and one vibrator 6 is installed on the first side platform 502, the second side platform 503, and the third side platform 504. All the vibrators 6 should be evenly distributed on the plane to ensure that all the concrete can be well vibrated.

[0054] In one embodiment, the material trough structure 7 includes: a top chute 701, a material distribution chute 702, and a first material channel 704 and a second material channel 705 corresponding to the liner assembly 5; the top chute 701, the material distribution chute 702, and the first material channel 704 and the second material channel 705 corresponding to the liner assembly 5 are all fixedly installed with the double-layer trolley assembly.

[0055] The top chute 701 is installed on the top of the first-layer platform 1 or the second-layer platform 2. A material distribution chute 702 is provided on the side of the top chute 701. The first material channel 704 corresponds to the end of the material distribution chute 702. A guide component 703 is provided between the first material channel 704 and the second material channel 705.

[0056] When in use, align the bottom of the material distribution chute 702 with the first material channel 704, and the concrete will be guided from the first material channel 704 to the corresponding lining work window. Alternatively, the first material channel 704 can be offset, and the guiding component 703 can be aligned with the material distribution chute 702, thereby guiding the concrete to the second material channel 705 using the guiding component 703.

[0057] In one embodiment, the grouting assembly 10 includes: a fixed flange 1002, a grouting pipe 1001, a detachable flange 1006, a pressure gauge 1003, a ball valve 1004, and a grouting connector 1005.

[0058] The fixed flange 1002 is fixedly connected to the liner assembly 5. The liner assembly 5 has an insertion port corresponding to the center hole of the fixed flange 1002. The outer side of the grouting pipe 1001 is fixedly connected to a detachable flange 1006. When in use, the detachable flange 1006 and the fixed flange 1002 are fixedly connected by fastening bolts (1007).

[0059] To facilitate monitoring of the grouting process, a pressure gauge 1003 and a ball valve 1004 are installed on the grouting pipe 1001, and a grouting connector 1005 is connected to the end of the grouting pipe 1001.
