Embodiment
[0032] Example: such as Figure 1-7 As shown, a water-rich railway tunnel trackbed mud-flushing disease prevention and control structure and its use method, consisting of a central ditch 1, a pebble filter layer 2, a coarse sand filter layer 3, a water collection well 4, a water collection well cover plate 5, and a drain hole 6. Tension spring 7 is formed. First construct the pebble filter layer 2 and coarse sand filter layer 3 for groundwater slag discharge and filtration; then build a water collection well 4 connected with the tunnel center ditch 1 under the inverted arch of the tunnel, set a drain hole 6 at the bottom of the water collection well 4 for drainage, and The bottom of the ditch 1 is provided with a water collection well cover 5, and the water collection well cover 5 is locked by the tension spring 7 arranged at the bottom of the water collection well 4; when the ground is rich in water, the amount of water infiltrated into the water collection well 4 reaches a c...

The invention discloses a preventing and treating structure for water-rich railway tunnel ballast bed mud pumping. The preventing and treating structure comprises a center gutter, a cobble filtering layer, a coarse sand filtering layer, a water-collecting well, a water-collecting well cover plate, a drain hole and an extension spring; the coarse sand filtering layer and the cobble filtering layer are sequentially arranged at the outer side of the water-collecting well, the drain hole is formed in the bottom of the water-collecting well, the water-collecting well communicated with the tunnel center gutter is constructed under an inverted arch of a tunnel, and the water-collecting well cover plate is arranged on the bottom face of the center gutter and is locked through the extension spring arranged at the bottom of the water-collecting well. By the adoption of the structure, in the process of constructing the water-rich railway tunnel, high-risk damage section is pretreated; when underground water is rich, after water permeates into the water-collecting well reaches certain pressure, the water automatically jacks the water-collecting well cover plate open and is drained into the center gutter, so that underground rich water is automatically drained, underground water pressure is released, and the effect of preventing and treating tunnel ballast bed mud pumping damage is achieved.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and relates to a tunnel disease prevention and control structure, in particular to a water-rich railway tunnel trackbed mud-flooding disease prevention and control structure and a use method thereof. Background technique [0002] With the gradual promotion of railway construction in my country, various risks and diseases faced by railway tunnel construction have become more and more complicated. Due to the influence of various factors such as geological conditions and construction technology, the mud-flowing disease is more likely to occur under the track bed of railway tunnels with rich groundwater, especially for tunnels with a length of more than 6 km and an integral track bed. If this disease occurs during operation, it will be severely affected. It is extremely difficult to control and eradicate due to severe conditions such as interruption of traffic, short renovation and constru...
