Description

A kind of rich water railway tunnel railway roadbed is risen soil disease control structure and its application method
Technical field
The invention belongs to Tunnel Engineering technical field, is related to a kind of tunnel defect control structure, more particularly to a kind of rich water Railway tunnel railway roadbed is risen soil disease control structure and its application method.
Background technology
With the progressively popularization of railway construction in China, the various risks and disease that Concerning Railway Tunnel Construction faces are also further multiple It is miscellaneous.Because all kinds of factors such as geological conditions, construction technology influence under the railway tunnel railway roadbed of rich groundwater, it is easier to burst and become muddy when a thaw sets in Mud disease, particularly length are emitted in 6 more than km and lays the tunnel of solid concrete roabed, if occurring this disease during operation, by can not Cut off traffic, the harsh conditions limitation such as treatment construction window time is short, solid concrete roabed is not easy-maintaining, administer eradicate it is extremely difficult. Therefore, after fully the origin cause of formation of this disease is grasped, effective design is taken during tunnel construction and is reliably applied Work measure is prevented, and is the optimal selection for eliminating this disease.Based on above mentioned problem, it is proposed that structure of the present invention, by disease Evil excessive risk location applies decompression discharge structure in advance, so as to realize the mesh actively drained underground rich water and discharge groundwater pressure , reach preventing and treating tunnel railway roadbed and rise soil the effect of disease.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, propose the rich water railway tunnel of set of system Road railway roadbed is risen soil disease control structure and its application method, is solved underground rich water railway tunnel railway roadbed disease of rising soil and is asked Topic, realize and actively drain underground water more than needed and release groundwater pressure.
The technical scheme is that:
A kind of rich water railway tunnel railway roadbed is risen soil disease control structure and its application method, including central trench, cobble Filter layer, coarse sand filter layer, sump, sump cover plate, spilled water hole and extension spring, described sump are orderly arranged outside each Coarse sand filter layer and cobble filter layer, bottom of catchmenting set spilled water hole, and tunnel is built in the sump of tunnel central trench insertion Under road inverted arch, and sump cover plate is set in central trench basal surface position, sump cover plate is by being arranged at bottom of catchmenting Extension spring locks, and construction method is as follows:
(1), excavate out space needed for total in tunnel inverted arch bottom after, cast in situs and the insertion of tunnel central trench Sump, and in the pre-buried spilled water hole of surrounding side wall;
(2), in sump be orderly arranged outside each coarse sand filter layer and cobble filter layer;
(3), central trench basal surface position install sump cover plate;
(4), in bottom installation extension spring of catchmenting, extension spring bottom be locked in bottom of catchmenting, tip locks in Sump cover plate, during the rich water of underground, penetrate into sump water reach certain pressure after can push up opener well cover plate automatically simultaneously Central trench is discharged into, so as to realize the purpose actively drained underground rich water and discharge groundwater pressure, reaches preventing and treating tunnel railway roadbed and turns over Slurry emits the effect of mud disease.
As the preferred technical solution of the present invention:
The cobble filter layer is disposed circumferentially sump outermost, and the surrounding width that bankets is 0.5m, and cobble particle diameter is 80~120mm。
For the coarse sand filter layer around being adjacently arranged on the outside of sump, the surrounding width that bankets is 0.5m;Coarse sand particle diameter For 0.5 ~ 2mm.
The sump and top tunnel central trench one-piece casting, using reinforced concrete structure;Interior headroom size is The cm of the cm of length × width × height=50 × 60 × 50 cm, wall thickness 25cm.
The sump cover plate is stainless steel trench cover, and physical dimension is cm × 15 of the cm of length × width x thickness=60 × 30 Cm, sump cover plate is fixed in central trench water (flow) direction rear end using bolt, front end and side wall overlap joint and surrounding cohesive position are adopted Waterproof is wrapped up with sealing rod.
The spilled water hole uses Φ 60mm stainless steel tubes, is embedded in sump surrounding and bottom in advance, and in coarse sand filter layer one Side head parcel thin wire gauze and non-woven fabrics filter water source, arrangement spacing are 20cm.
The extension spring bottom is locked in bottom of catchmenting, and tip locks are under normal circumstances in sump cover plate Extended state is tight to ensure cover plate covering, during rich water when water pressure is more than cover plate deadweight and spring tension sum, just Cover plate can be automatically opened up and realize draining.
Railway roadbed disease control structure of rising soil is equally applicable to similar rich water railway tunnel.
The present invention is as follows using step:
(1)According to the specific hydrogeologic condition of Tunnel Engineering, disease excessive risk location is average at a certain distance in tunnel Arrangement railway roadbed is risen soil disease control structure;
(2)Railway roadbed disease control structure of rising soil applies step everywhere:1. excavate out whole knot in tunnel inverted arch bottom Behind space needed for structure, cast in situs sump reinforced concrete structure, poured together with this section of central trench, and it is pre- in surrounding side wall Bury spilled water hole;2. apply cobble filter layer and coarse sand filter layer successively from outside to inside;3. sump cover plate is installed;4. installation stretching Spring.
Beneficial effects of the present invention are:
The present invention rises soil disease control structure and its application method for a kind of rich water railway tunnel railway roadbed, by disease Evil excessive risk location applies drop and drainage structure in advance, so as to realize the mesh actively drained underground rich water and discharge groundwater pressure , reach preventing and treating tunnel railway roadbed and rise soil the effect of disease.
