Therefore, the existing chamber templates are all temporarily manufactured on site by workers, so that the reusability of the chamber templates is poor; when concrete is cast, the tunnel main line lining and the chamber lining are usually cast together, so that the cast concrete amount is large, the casting pressure is large, and the concrete vibration operation condition is not provided; in addition, the chamber template also often has the problems of deformation, mold running, concrete slurry leakage and the like; moreover, because the chamber form is simply assembled, the joint seam of the small steel plate 94 seriously affects the smoothness of the surface of the chamber 92.

In conclusion, the existing construction method easily causes the defects of incompact concrete, insufficient strength, poor forming quality of the lining curved surface of the opening of the chamber, poor appearance of the concrete surface and the like, and leaves great potential safety hazards for later line operation, tunnel maintenance and the like.

With reference to fig. 11 to 13, a method of using the tunnel chamber lining trolley 100 is briefly described as follows:

when the chamber lining pouring construction is to be carried out, the tunnel chamber lining trolley 100 is moved into the chamber at the excavation position, and at the moment, the chamber is already subjected to primary concrete construction and chamber bottom surface construction.

And then, installing a measuring lofting position to position the tunnel chamber trolley, adjusting the position of the trolley body unit 1 according to the measuring lofting center line, and controlling the second ends of the telescopic support legs 5 to be supported on the ground of the chamber after the adjustment is finished. Wherein the length of the tunnel chamber lining trolley 100 can be adjusted according to the depth of the chamber.

Then, the position of the top die unit 3 can be adjusted by the adjusting unit 6; then, the second driving module 32 of the top die unit 3 drives the top die set 31 to move by a certain height, so that the top die set 31 pushes the first arch top die 2112 of the side die unit 2 by a certain height.

Then, the first driving module 22 of the side module 2 drives the side module 21 to move to the design position in the width direction of the vehicle body unit 1; subsequently, the second driving module 32 of the top mold unit 3 drives the top mold block 31 to move to the design position, so that the top mold block 31 and the side mold blocks 21 form a circumferential molding surface of the chamber lining.

Next, the positions of the first arch top mold 2112 and the first bottom mold 2114 are adjusted, respectively, and the first telescopic rod 2311 and the second telescopic rod 2312 of the first telescopic rod group 231 support the first arch top mold 2112 and the first bottom mold 2114, respectively, and limit the first arch top mold 2112 and the first side mold 2113.

Meanwhile, in the concrete pouring process, the first attached vibrating unit and the second attached vibrating unit are started to vibrate the concrete lined in the underground chamber, so that the compactness and the appearance quality of the concrete lined in the underground chamber are ensured.

When the strength of the concrete meets the stripping condition, firstly, stripping the main lining trolley 101, and then moving the main lining trolley 101; next, the tunnel chamber lining trolley 100 is demolded. When the tunnel chamber lining trolley 100 is demolded, the second driving module 32 of the top die unit 3 drives the top die to move downwards; then the first supporting module releases the support of the side module 21, and the first arch top mould 2112 of the side module 21 of the side module 2 is separated from the chamber lining; then, the first side die 2113 and the first bottom die 2114 are controlled to be separated from the chamber lining through the first driving module 22, and then the first bottom die 2114 is folded and contracted; then the support of the telescopic support legs 5 to the vehicle body unit 1 is released; then the support of the second supporting end wall module 41 is released, and then the end wall bottom die assembly 413, the end wall middle die assembly 412 and the end wall top die assembly 411 are demolded with the chamber lining in sequence; finally, the tunnel chamber lining trolley 100 is removed from the chamber.
