[0002] When long-distance tunnel construction is carried out, parallel or inclined auxiliary tunnels are usually designed to speed up the construction progress, and the working face of the main tunnel is increased through the auxiliary tunnels. The cross section of the auxiliary tunnel is usually small, and cast-in-place concrete is usually used to lay the road surface during construction to ensure the rapid passage of vehicles in the tunnel.

[0003] After the cast-in-place concrete construction, a period of time is required, and vehicles can pass through only after the concrete hardens to a certain strength. The cast-in-place concrete road surface construction will affect the auxiliary tunnel construction and increase the tunnel auxiliary tunnel construction period. At the present stage, the auxiliary tunnel concrete road surface is not usually constructed, and the concrete road surface of the tunnel is constructed at one time after the tunnel is excavated for a long distance. However, the long distance of the tunnel excavation takes a long time, affects the rapid passage of vehicles, and causes the overall construction time to be unable to be shortened.

[0036] It should be noted that the cement mortar 3 can fill the grouting space and is in contact with the splicing block 1 and the mounting rock surface 51 respectively, and when the cement mortar 3 solidifies, the splicing block 1 is bonded to the mounting rock surface 51, thereby improving the structural strength and stability of the driving road surface.

[0037] Compared with the prior art, the tunnel quick-mounting type auxiliary tunnel driving road surface assembly provided in the embodiment arranges a plurality of splicing blocks 1 on the mounting rock surface 51 of the tunnel 5, quickly forms a driving road surface through the splicing blocks 1, greatly advances the construction time of the auxiliary tunnel surface of the tunnel 5, enables the auxiliary tunnel surface of the tunnel 5 to be quickly constructed, shortens the construction period of the auxiliary tunnel surface of the tunnel 5, avoids the problem that cast-in-place concrete construction affects the excavation and tunneling construction of the tunnel 5, improves the construction speed of the auxiliary tunnel road surface of the tunnel 5, and improves the construction efficiency.

[0038] In some embodiments, referring to Figure 1 and Figure 4 , the bottom of the splicing block 1 is provided with a plurality of support plates 12, the plurality of support plates 12 are arranged at intervals along a direction perpendicular to the extension direction of the tunnel 5, the grouting channel 13 is formed between the two adjacent support plates 12, and the extension direction of the grouting channel 13 is parallel to the extension direction of the tunnel 5. The plurality of support plates 12 support the splicing block 1, the plurality of support plates 12 are arranged at intervals and jointly support the main body of the splicing block 1, can also be beneficial to the formation of the grouting channel 13, the spatial sizes of the plurality of grouting channels 13 are the same, so that the grouting can be simultaneously started or stopped during grouting, and the complexity of operation is reduced.

[0039] In specific implementation, the sizes of the plurality of grouting channels 13 are the same, the splicing block 1 is provided with a plurality of grouting holes 11, the grouting hole 11 and the grouting channel 13 correspond to each other, synchronous grouting is facilitated, and the grouting efficiency is improved.

After the plurality of splicing blocks 1 are installed, the water on both sides of the splicing block 1 in the tunnel can be collected and discharged through the drainage groove 121, and the water accumulation in the tunnel is avoided.

[0041] In actual implementation, the plurality of drainage grooves 121 are collinear, and the straight line where the plurality of drainage grooves 121 are located is perpendicular to the extension direction of the tunnel 5, thereby shortening the flow path of water and facilitating the flow of water.

[0042] In some embodiments, referring to Figure 1 , the drainage channel 2 is formed between one side of the splicing block 1 and the side wall of the tunnel 5. The side of the splicing block 1 is close to the side wall of the tunnel 5, and the other side forms the drainage channel 2.

[0045] In some embodiments, referring to Figure 1 and Figure 3 , the upper surface of the splicing block 1 gradually inclines upward in a direction away from the drainage channel 2. In order to better guide the flow of water on the driving surface, the height of one side of the splicing block 1 close to the drainage channel 2 is lower than the height of the other side of the splicing block 1, and the water can flow from high to low under the action of its own gravity.

[0046] In actual implementation, support plates 12 of different heights are provided, and the top heights of the plurality of support plates 12 gradually increase in a direction away from the drainage channel 2, so that the driving surface gradually inclines.

The adjacent pre-buried sleeves 41 are inserted into the corresponding pre-buried rods 42. The pre-buried sleeve 41 and the pre-buried rod 42 can be inserted, thereby improving the connection strength and stability of the adjacent splicing blocks 1 and improving the driving safety in use. The pre-buried sleeve 41 and the pre-buried rod 42 form a force transmission structure system after being inserted, thereby facilitating force transmission.

[0049] In specific implementation, the end surface of the pre-buried sleeve 41 is flush with the end surface of the splicing block 1. After the pre-buried rod 42 is inserted into the pre-buried sleeve 41, the gap between the adjacent splicing blocks 1 is very small, thereby facilitating driving.

[0050] In some embodiments, a threaded pipe is connected inside the grouting hole 11 and communicates with the grouting device. The threaded pipe facilitates the communication between the grouting hole 11 and the grouting device, thereby reducing the connection difficulty.

[0051] In specific implementation, an external thread can be arranged at the end of the grouting pipe of the grouting device. The grouting pipe and the threaded pipe are screwed, thereby facilitating grouting operation.

[0052] Optionally, the grouting device can adopt a grouting pump. The grouting pump communicates with the grouting hole 11 through the grouting pipe.
