Problems solved by technology

[0004] The object of the present invention is to provide a tunnel drainage device and a tunnel integral ballast in view of the problems in the prior art that there is water seepage at the bottom of the tunnel and cannot be smoothly discharged, which leads to arching and cracking of the integral track bed of the tunnel, thereby affecting the normal operation of the tunnel and the safety of the tunnel. The tunnel drainage device is pre-buried in the integral track bed of the tunnel. The drainage device is equipped with a drainage cavity that runs through the entire track bed of the tunnel, so that the seepage water at the bottom of the tunnel is discharged through the drainage device, and then the water pressure of the integral track bed is released to ensure the normal operation of the tunnel. and the overall safety of the tunnel

Embodiment 1

[0063] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the tunnel drainage device 1 includes a drainage cylinder main body 11 for pre-embedding in the integral ballast bed 2 of the tunnel. The drainage cylinder main body 11 is a cylindrical structure. The embedded end 111 inside, and the drainage end 112 extending out of the integral ballast bed 2 of the tunnel, the embedded end 111 communicates with the drainage end 112.

[0064] Through the tunnel drainage device 1 of this solution, the tunnel drainage device 1 is pre-embedded in the integral ballast bed 2 of the tunnel, the seepage water at the bottom of the tunnel penetrates into the main body 11 of the drainage tube, and the cavity space in the main body 11 of the drainage tube is used to collect and store seepage water , the embedded end 111 communicates with the drainage end 112, the seepage water flows to the drainage end 112 through the embedded end 111, and the seepage water is discharged...

Embodiment 2

[0076] like Figure 4 and Figure 5 As shown in the tunnel integral ballast bed 2, the tunnel drainage device 1 as described above is pre-embedded in the tunnel integral ballast bed 2, and the tunnel drainage device 1 is buried in the tunnel integral ballast bed 2 before pouring the ballast bed concrete, effectively avoiding stress The steel bar does not affect the overall mechanical performance of the ballast bed, ensures the structural strength of the overall ballast bed 2 of the tunnel, and can effectively discharge water seepage in the ballast bed, ensuring the safety of the ballast bed and the tunnel.

[0077] Further, the tunnel drainage device 1 is arranged on the centerline of the integral ballast bed 2 of the tunnel.

[0078] As one of the implementations, the tunnel drainage devices 1 are arranged sequentially along the length direction of the tunnel, the distance between two adjacent tunnel drainage devices 1 is 3-6m, and the overall track bed 2 of the tunnel is pr...

Embodiment 3

[0083] The construction method of the tunnel drainage device, when the tunnel drainage device as in embodiment 1 is used to discharge the water seepage process of the integral ballast bed of the tunnel, proceed according to the following construction steps:

[0084] a. If figure 1 As shown, the assembly of the tunnel drainage device 1 includes connecting the embedded end 111 of the drainage cylinder main body 11 to the base 12 that closes one end of the drainage cylinder main body 11, and the drainage cylinder main body 11 and the base 12 are provided with water-permeable holes 123, Take anti-leakage measures for the tunnel drainage device 1, then pour permeable material into the main body 11 of the drainage tube, and remove the anti-leakage measures after the permeable material is solidified;

[0085] b. If Figure 6 As shown, the rail row 5 is assembled and the track bed steel bars are bound, and the rail 51, the fastener 52 and the sleeper 53 are assembled into an overall ...

Abstract

The invention relates to the technical field of tunnel construction, and particularly relates to a tunnel drainage device and a tunnel monolithic track bed. The tunnel drainage device comprises a drainage tube main body for being embedded in the tunnel monolithic track bed, the drainage tube main body has a tubular structure and comprises a pre-embedded end arranged in the tunnel monolithic trackbed, and a drainage end extending out of the tunnel monolithic track bed, the pre-embedded end is communicated with the drainage end, the tunnel drainage device is pre-embedded in the tunnel monolithic track bed, a drainage cavity penetrating through the tunnel monolithic track bed is arranged in the drainage device, so that water seepage at the bottom of a tunnel is drained through the drainage device so as to further release the water pressure of the monolithic track bed and guarantee the normal running and whole safety of the tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel drainage device and a tunnel integral ballast bed. Background technique [0002] Many tunnels in our country are in complex geological conditions, and the groundwater is rich in development. In addition, due to the uneven construction quality of the tunnels and the inadequate implementation of drainage measures, the water seepage of many tunnels is very serious, especially the tunnels constructed by underground excavation Inside, water seepage is even more serious. [0003] For ordinary railway tunnels and subway tunnels, the water seepage at the top of the tunnel and the side walls of the tunnel can generally flow down the tunnel wall and be removed through the drainage ditch. However, since the bottom of the tunnel generally needs to lay an integral ballast bed, the water seepage at the bottom of the tunnel will seep into the integral ballast bed , Difficu...
