Description

Technical Field

[0001] The utility model relates to the technical field of single-layer lining drainage, in particular to an arch foot drainage structure of a single-layer lining. Background Art

[0002] Single-layer lining refers to a protective layer covering the inner wall of the tunnel, which is used for waterproofing and support. When the protective layer is protecting, the accumulated water in the soil layer will flow to the surface of the single-layer lining and cause infiltration. Therefore, the water flowing to the single-layer lining needs to be discharged.

[0003] The existing drainage is achieved by setting up a water collection channel at the arch foot of the single-layer lining, and then flowing into the drainage channel through a flow channel for discharge. This will result in the connecting flow channel being hidden at the bottom of the tunnel. Therefore, when water enters the flow channel through the water collection channel, the sludge and sand it carries will be carried by the water flow and attached to the flow channel, making it difficult to clean it, and it is easy to accumulate and cause blockage, affecting the discharge of water. Utility Model Content

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Combine the following Figures 1 to 4 The utility model is described in detail.

[0023] A single-layer lining arch foot drainage structure includes a tunnel lining 1, a tunnel floor 101 is arranged at the middle bottom of the tunnel lining 1, water accumulation channels 102 are arranged at both ends of the tunnel floor 101, drainage ditches 103 are arranged near both ends of the tunnel floor 101, a connecting cavity 104 is arranged between the water accumulation channel 102 and the drainage ditch 103, an anti-blocking component is arranged in the middle of the connecting cavity 104, and the anti-blocking component swings along the axis.

[0024] First, water accumulation channels 102 are set at both ends of the tunnel bottom plate 101 near the arch foot of the tunnel lining 1. The water accumulated in the soil layer outside the tunnel lining 1 flows along the water accumulation channel 102, so that the water in the water accumulation channel 102 flows to the connecting cavity 104, and the water flow is discharged into the drainage ditch 103 through the connecting cavity 104 for removal, thereby preventing the accumulated water in the soil layer from penetrating the tunnel lining 1 and causing the tunnel lining 1 to be corroded by water.

[0025] Furthermore, the anti-blocking component includes a rotating shaft 1041, a cleaning block 1042, a brush 1043 and a deflection rod 1044. The rotating shaft 1041 is arranged on one side of the middle part of the connecting chamber 104, the cleaning block 1042 is arranged on one side of the rotating shaft 1041, the brush 1043 is arranged at the bottom of the cleaning block 1042, the deflection rod 1044 is arranged on one side of the rotating shaft 1041, the rotating shaft 1041 is arranged on one side of the connecting chamber 104 close to the drain ditch 103, and the rotating shaft 1041 is close to both sides of the connecting chamber 104, the two ends of the rotating shaft 1041 are connected to the middle part of the connecting chamber 104 through a torsion spring, the cleaning block 1042 is extended in a long strip shape on one side of the rotating shaft 1041, the deflection rod 1044 is a round rod protruding from one side of the rotating shaft 1041, and the deflection rod 1044 is arranged at an angle to the cleaning block 1042, and the connecting chamber 104 is an inclined extending cavity.

[0026] When the water that infiltrates from the soil layer flows through the connecting cavity 104, some of the sludge and sand will adhere to the connecting cavity 104. At this time, the deflection rod 1044 on one side of the rotating shaft 1041 can be controlled to apply force to drive the rotating shaft 1041 to rotate. When the rotating shaft 1041 rotates, it will drive the cleaning block 1042 to deflect along the axis. When the cleaning block 1042 deflects, the brush 1043 at the bottom will fit the middle bottom of the connecting cavity 104 for brushing, so as to brush the sludge and sand attached to the surface out of the connecting cavity 104, so as to avoid the accumulation of sludge and sand in the connecting cavity 104, causing the connecting cavity 104 to be blocked. At the same time, the torsion spring connection at both ends of the rotating shaft 1041 can enable the rotating shaft 1041 to reset and rotate after cleaning, thereby driving the cleaning block 1042 to reset, so as to facilitate the cleaning of the connecting cavity 104 and avoid the difficulty in cleaning due to the position relationship of the connecting cavity 104.

[0027] The following is a specific implementation process of the utility model. First, water accumulation channels 102 are set at both ends of the tunnel floor 101 near the arch foot of the tunnel lining 1. The water accumulated in the soil layer outside the tunnel lining 1 flows along the water accumulation channel 102, so that the water in the water accumulation channel 102 flows to the connecting cavity 104, and the water flow is discharged into the drainage ditch 103 through the connecting cavity 104 for removal, so as to prevent the accumulated water in the soil layer from penetrating the tunnel lining 1 and causing the tunnel lining 1 to be corroded by water. When the water flow that penetrates from the soil layer flows from the connecting cavity 104, part of the sludge and sand will adhere to the connecting cavity 104. At this time, the deflection rod 1044 on one side of the rotating shaft 1041 can be controlled to apply force to make it The rotating shaft 1041 is driven to rotate, and when the rotating shaft 1041 rotates, the cleaning block 1042 is driven to deflect along the axis, and when the cleaning block 1042 is deflected, the brush 1043 at the bottom thereof will fit against the middle bottom of the connecting cavity 104 for brushing, so as to brush the sludge and sand attached to the surface out of the connecting cavity 104, so as to avoid the accumulation of sludge and sand attached to the connecting cavity 104, causing the connecting cavity 104 to be blocked. At the same time, the torsion spring connection at both ends of the rotating shaft 1041 can enable the rotating shaft 1041 to reset and rotate after cleaning, thereby driving the cleaning block 1042 to reset, so as to facilitate the cleaning of the connecting cavity 104, and avoid the difficulty in cleaning due to the position relationship of the connecting cavity 104.
