Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a trolley for the construction of the secondary lining of a tunnel as shown in Figures 1-4 Figure, which includes a frame 1. A roller 2 for the movement of the frame 1 is arranged at the bottom of the frame 1. It further includes:

[0025] A top workbench 3, which is used for workers to work on the top of the frame 1;

[0026] A side workbench 5, which is used for workers to work on the side of the frame 1. The side workbench 5 includes a standing net 51 for workers to stand on. A support mechanism for supporting the standing net 51 is arranged at the bottom of the standing net 51. The support mechanism includes a fixed arm 52, and an adjusting component for adjusting the size of the side workbench 5 is arranged at the end of the fixed arm 52;

[0027] A water pipe 6, which is used for sprinkler curing;

[0028] A fixing plate 7, which is used for binding and fixing the water pipe 6.

[0029] Specifically, the top end of the frame 1 is fixedly connected to the bottom end of the top workbench 3. First limiting frames 4 for inserting the fixing plate 7 are fixedly connected to both sides of the top workbench 3 respectively.

[0030] Furthermore, the frame 1 is welded and processed by I-beams. The frame 1 is integrally in a portal shape. The bottom end of the top workbench 3 is welded to the top end of the frame 1. A steel bar mesh is laid on the top end of the top workbench 3 for workers to stand on the top end of the top workbench 3. A ladder is welded in the vertical direction on the side of the frame 1 for workers to get on and off the frame 1. A plurality of rollers 2 are symmetrically arranged on both sides of the bottom of the frame 1. The frame 1 is pulled by a tractor to make the rollers 2 rotate, so as to realize the movement of the frame 1. The first limiting frames 4 are symmetrically arranged on both sides of the top workbench 3, and the part where the first limiting frames 4 contact the top workbench 3 is fixed by welding.

[0031] Specifically, one end of the fixed arm 52 is fixedly connected to one side of the frame 1, and a groove is opened at the other end of the fixed arm 52 for installing the adjusting component. The adjusting component includes an adjusting arm 53, which is slidably inserted into the groove. A locking hole is opened on the front surface of the inner wall of the groove. An adjusting hole for adjusting the position of the adjusting arm 53 is opened on the front surface of the adjusting arm 53. A locking piece for fixing the position of the adjusting arm 53 is arranged at the end of the fixed arm 52. The locking piece includes a locking bolt 54, which is inserted into the adjusting hole and the locking hole. A plug rod 55 is fixedly connected to the top end of the adjusting arm 53. A round hole is opened at the top end of the standing net 51, and the plug rod 55 is inserted into the round hole. A second limiting frame 56 is fixedly connected to one end of the adjusting arm 53 for inserting the fixing plate 7.

[0032] Furthermore, four sets of side workbenches 5 are provided and symmetrically arranged on both sides of the vehicle frame 1 respectively. At the bottom end of a standing net 51, two fixed arms 52 are symmetrically arranged. The part where the fixed arm 52 contacts the vehicle frame 1 is fixed by welding. The vertical cross-sectional dimension of the adjusting arm 53 is 0.98 times that of the vertical cross-sectional dimension of the groove. The sizes of the locking hole and the adjusting hole are the same, both being 1.02 times the outer diameter of the locking bolt 54. A plurality of adjusting holes are horizontally arranged at equal intervals on the front surface of the adjusting arm 53. By inserting the locking bolt 54 into the locking hole and different positions of the adjusting holes, and then installing nuts on the outer wall of the end of the locking bolt 54 after insertion, the position of the adjusting arm 53 can be fixed, so as to adjust the length of the adjusting arm 53 extending out of the fixed arm 52, complete the length adjustment of the side workbench 5 on the side of the vehicle frame 1, and adapt to different widths of the tunnel. The standing net 51 is a steel mesh. By inserting the inserting rod 55 into the round hole of the standing net 51, the installation of the standing net 51 is carried out to prevent the standing net 51 from generating displacement, thus facilitating the standing of the staff. At the end of the top workbench 3 and the end of the adjusting arm 53 far from the fixed arm 52, a first limiting frame 4 and a second limiting frame 56 are respectively welded. By inserting the fixing plate 7 into the first limiting frame 4 and the second limiting frame 56 at the same time, the fixing plate 7 is forced to bend into an arc shape. The fixing plate 7 can be made of easily bendable materials such as rubber tubes and plastic tubes. Then, the water pipe 6 is tied and fixed to the fixing plate 7 through a cable tie. A plurality of spray heads are arranged on the side of the water pipe 6 far from the vehicle frame 1. One end of the water pipe 6 is connected to the water pipe arranged inside the tunnel in a penetrating manner. The water source is pumped into the water pipe 6 by a water pump and then sprayed by the spray heads to realize the curing effect on the secondary lining. Two sets of water pipes 6 are provided and respectively arranged at the head and tail ends of the vehicle frame 1.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
