As the preferred technical solution of the present invention:
Described cobble filter course is disposed circumferentially sump outermost, and the surrounding width that bankets is 0.5m, and cobble particle diameter is 80 ~ 120mm.
Described coarse sand filter course is around being adjacently arranged in outside sump, and the surrounding width that bankets is 0.5m；Coarse sand particle diameter is 0.5 ~ 2mm.
Described sump and tunnel, top central trench one-piece casting, all use reinforced concrete structure；Interior headroom a size of cm × 50, cm × 60, length × width × height=50 cm, wall thickness 25cm.
Described sump cover plate is rustless steel trench cover, physical dimension is cm × 30, length × width x thickness=60 cm × 15 cm, and sump cover plate uses bolt to fix in central trench water (flow) direction rear end, front end uses sealing rod parcel waterproof with sidewall overlap joint and surrounding cohesive position.
Described spilled water hole uses Φ 60mm stainless steel tube, is embedded in sump surrounding and bottom in advance, and filters water source in termination, coarse sand filter course side parcel thin wire gauze and non-woven fabrics, and arrangement pitch is 20cm.
Described stretching spring bottom end is locked in bottom sump, tip locks is in sump cover plate, it is in extended state under normal circumstances tight to ensure that cover plate covers, during rich water when water pressure is more than cover plate deadweight and spring tension sum, just can automatically open up cover plate and realize draining.
Described railway roadbed disease control structure of rising soil is equally applicable to similar rich water railway tunnel.
The present invention uses step as follows:
(1) according to the concrete hydrogeologic condition of Tunnel Engineering, in tunnel, disease excessive risk location the most averagely arranges that railway roadbed is risen soil disease control structure；
(2) railway roadbed disease control structure of rising soil applies step everywhere: after 1. excavating out total requisite space bottom tunnel inverted arch, and cast in situs sump reinforced concrete structure pours together with this section of central trench, and in the pre-buried spilled water hole of surrounding sidewall；Apply cobble filter course and coarse sand filter course the most successively；3. sump cover plate is installed；4. stretching spring is installed.
The invention have the benefit that
The present invention rises soil disease control structure and construction method for a kind of rich water railway tunnel railway roadbed, by applying drop and drainage structure in advance in disease excessive risk location, thus realize actively draining underground rich water and the purpose of release groundwater pressure, reach to prevent and treat tunnel railway roadbed and rise soil the effect of disease.
