Problems solved by technology

However, for the small tunnel slag generated during the subsequent secondary lining construction and the construction of the inverted arch filling layer and scattered on the top of the inverted arch filling layer, the cost of using large machinery to transport and discharge the slag is too high, and the efficiency of manual cleaning is low. Very low, thereby delaying the overall tunnel construction process

Embodiment 1

[0030] A full-section tunnel rapid drainage and slag discharge system in this embodiment, such as figure 1 As shown, the inside of the tunnel is provided with initial support 01 and secondary lining 02 in turn from outside to inside, the bottom inverted arch top of the tunnel is provided with inverted arch filling layer 03, and the rapid drainage and slag discharge system includes several along the The aqueduct 1 is linearly arranged between the initial support 01 and the secondary lining 02 in the length direction of the tunnel, the two sides of the inverted arch filling layer 03 are provided with side drains 2 along the length of the tunnel, and the aqueduct 1 is close to The inverted arch filling layer 03 is linearly provided with a number of side drain pipes 3 that are connected with the aqueduct 1 and lead to the side drain 2 along the length of the tunnel; the top of the tunnel is provided with the middle drain pipe that communicates with the aqueduct 1 4, the water outl...

Embodiment 2

[0034] This embodiment is further optimized on the basis of Embodiment 1, such as figure 1 and figure 2 As shown, one end of the side drainage ditch 2 extending to the outside of the tunnel is provided with a water collection pit 7, and a return water pipe 8 is arranged in the water collection pit 7, and the return water end of the water return pipe 8 extends to the inner side of the tunnel close to At the palm face and leading to the side drain 2.

[0035] The accumulated water passing through the side drainage ditch 2 finally flows to the sump 7 outside the tunnel for temporary storage. When there is a lot of tunnel slag in the side drainage ditch 2, the water pump on the return pipe 8 is turned on, and the inside of the sump 7 is emptied. The accumulated water is sucked back to the end of the side drainage ditch 2 close to the tunnel face, and the tunnel slag inside the side drainage ditch 2 is washed twice by the backflowing water, so as to avoid the tunnel slag in the s...

Embodiment 3

[0039] This embodiment is further optimized on the basis of the above-mentioned Embodiment 1 or 2, such as figure 1 As shown, it also includes an auxiliary drainage ditch 9 arranged on one side of the side drainage ditch 2 . The side of the auxiliary drainage ditch 9 close to the side drainage ditch 2 is linearly provided with a plurality of drainage holes communicating with the side drainage ditch 2 .

[0040] The top of the auxiliary drainage ditch 9 is connected to the top of the side drainage ditch 2 through the drainage hole. When the water level in the side drainage ditch 2 exceeds the height of the drainage hole, the accumulated water in the side drainage ditch 2 enters the auxiliary drainage through the drainage hole. Ditch 9 to avoid overflow of the accumulated water in the side drainage ditch 2.

[0041] At the same time, by monitoring the water output of the auxiliary drainage ditch 9, when the water output in the auxiliary drainage ditch 9 is large, it means that t...

Abstract

The invention discloses a full-section tunnel rapid drainage and slag discharge system, which realizes rapid drainage and slag discharge inside the tunnel; at the same time, the invention also discloses a full-section tunnel rapid drainage and slag discharge construction method. The flow is controlled, and then the tunnel slag on the filling layer of the inverted arch is washed to the side drainage ditch through the accumulated water, and the slag is quickly drained through the side drainage ditch; the accumulation of tunnel slag or water accumulation in the tunnel is effectively avoided, and the tunnel is improved. construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a full-section tunnel rapid drainage and slag discharge system and a construction method. Background technique [0002] With the development of my country's transportation construction industry, more and more tunnels have been built. With the improvement of traffic planning requirements, the tunnel section has gradually become larger and larger. Now, for large-section tunnels, smooth blasting is generally used for one-time excavation. Then, initial support and secondary lining are applied, and the large-scale tunnel slag generated during blasting can be quickly transported out of the tunnel by machinery such as excavators. However, for the smaller tunnel slag generated during the subsequent secondary lining construction and the construction of the inverted arch filling layer and scattered on the top of the inverted arch filling layer, the cost of transporti...
