[0002] In traditional TBM construction, the secondary lining of tunnels is constructed only after the tunnel is fully penetrated, and the secondary lining adopts a construction mode in which the invert arch and the arch wall lining are constructed separately, which has a great impact on the project schedule.

Traditional lining trolleys use hydraulic components (or screws) to control the retraction and contraction of the trolley panels, enabling the erection and removal of lining formwork. Because the hydraulic components (or screws) and the retraction of the panels require a certain amount of space, the trolley's internal rods are numerous, making on-site operations inconvenient.

11. A method for constructing a full-circle synchronous lining of a TBM-constructed tunnel using the full-circle synchronous lining trolley for TBM-constructed tunnel according to any one of claims 1 to 10, characterized in that: The method comprises the following steps: 1) moving the front floating Y-type turnout forward; 2) removing the original track under the turnout and simultaneously cleaning the tunnel bottom; 3) moving the needle beam forward; 4) installing the rear track; 5) moving the rear floating Y-type turnout forward; 6) moving the steel bar trolley forward and installing the steel bar; 7) moving the lining trolley and the maintenance trolley forward and simultaneously maintaining the rear lining; 8) lining construction.

12. The TBM tunnel full-circle synchronous lining construction method according to claim 11, characterized in that: In the step 8), the lining trolley (7) is moved to the lining pouring position, the bottom support A (20) and the anti-floating support (701) are adjusted, and the lining trolley (7) is put into place; the air bag (904) is inflated to the specified value from bottom to top, so that the air bag (904) panel expands to the designed lining surface, the inflation valve (903) is closed to maintain pressure, and then the lining end is sealed, and the lining concrete is poured from the feeding port (11) from bottom to top. When the lining concrete pouring surface is almost at the feeding port (11), the steel seal (1103) is installed, and the feeding port (11) is sealed using the L-shaped pressure plate (1105) and the steel seal (1103), and the concrete is continued to be poured from the upper feeding port (11) until the lining pouring is completed; after the lining concrete pouring is completed, when the concrete strength reaches the specified value, all the steel seals (1103) are removed, and each is opened from top to bottom. The inflation valve (903) of the airbag (904) releases the air in the airbag (904), and the feeding port (11) is pulled back and fixed, and then the air in the airbag (904) is completely exhausted by using the vacuum pump. The airbag (904) is retracted, compressed and adsorbed on the cylindrical ring beam (8), and the trolley demoulding is completed at this time; the bottom support B (1203) at the bottom of the needle beam (12) is retracted, so that the needle beam (12) falls on the roller at the bottom of the lining trolley (7), and the needle beam (12) is moved forward by rotating the hydraulic motor (1504). After the needle beam (12) moves into place, the bottom supports B (1203) at both ends of the needle beam (12) are lowered to support the needle beam (12), and the lining trolley (7) is lifted on the needle beam (12), and the hydraulic motor (1504) set on the lining trolley (7) is started to move the lining trolley (7) forward to the next lining construction position.

13. The TBM tunnel full-circle synchronous lining construction method according to claim 12, wherein: In step 6) and step 7), the movement method of the steel bar trolley (17) and the maintenance trolley (18) is the same as that of the lining trolley (7) in step 8).

14. The TBM tunnel full-circle synchronous lining construction method according to claim 13, wherein: In the step 7), when the lining trolley (7) moves forward, the ventilation hose (2) is untied from the tunnel arch in the forward direction of the trolley. As the trolley moves, the ventilation hose (2) in the forward direction is retracted and sleeved on the flat barrel-shaped hard air duct (201). The ventilation hose (2) sleeved on the end of the flat barrel-shaped hard air duct (201) is pulled out from the rear of the trolley and re-suspended on the wire rope of the tunnel arch. After the trolley moves into place, the ventilation hose (2) is fastened and fixed to the flat barrel-shaped hard air duct (201) using a fastening tie, and normal ventilation can be restored. If the ventilation efficiency is low, a pressurized fan is added to the flat barrel-shaped hard air duct (201) to assist ventilation.
