Abstract
The utility model relates to a supporting structure of a district passing through a cavern and an underground river for a tunnel, which comprises an upper tunnel structure and a lower arch bridge. The supporting structure is characterized in that the upper tunnel structure is an open structure having a bottom corresponding to the cavern and the underground river and comprises a sprayed concrete layer (1), a secondary lining (2) and a system anchor rod (3), the lower arch bridge is positioned above the cavern and the underground river at the bottom of the upper tunnel structure and comprises arch rings (4) and arch seats (5), the arc rings are longitudinally arranged along the tunnel, and two sides of the cavern and the underground river (7) with two ends positioned at the bottom of the upper tunnel structure are stably arranged on base rocks. The supporting structure is clear in stress, simple in structure, convenient in construction and high in reliability, and can avoid post-construction settlement possibly caused by backfill and affection to an underground water environment.
Description
Technical field
The utility model relates to tunnel and underground engineering field, relates in particular to and strides location, solution cavity underground river supporting and protection structure on a kind of tunnel.
Background technology
China's karst is grown, but lava is grown in the zone that accounts for national total area 13.5%, the karst area constructing tunnel may meet with various type of karst, when striding solution cavity, underground river on the tunnel, because substrate backfill leakiness or unsettled, cause most probably that the basis subsides, structural deterioration, therefore must adopt effective supporting and protection structure, could guarantee to construct and operation security.
The general backfill rock quarrel that adopts when striding solution cavity, underground river on the tunnel at present, and the processing scheme of additional slip casting at the bottom of tunnel, but it is bigger to work as the solution cavity growth degree of depth, or solution cavity is when down being communicated with the underground river, and under the DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES effect, the substrate backfill layer very easily produces big settlement after construction during the operation, cause the tunnel structure cracking destruction, even may cause structural entity to be sunk, and cause environmental disruption, influence operation security.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, a kind of easy construction to be provided, and the structural reliability height can effectively be controlled settlement after construction, guarantees to stride location, solution cavity underground river supporting and protection structure on the tunnel of constructing tunnel and operation security.
The technical scheme in the invention for solving the technical problem is: stride location, solution cavity underground river supporting and protection structure on the tunnel, comprise top tunnel structure and bottom arch bridge, it is characterized in that: described top tunnel structure is the non-enclosed construction on corresponding solution cavity underground river, bottom, is made of pneumatically placed concrete layer 1, secondary lining 2, system anchor bolt 3; Described bottom arch bridge is positioned on the solution cavity underground river of tunnel structure bottom, top, is made of arch ring 4, abut 5, and described arch ring arranges vertically that along the tunnel two ends are positioned at 7 both sides, solution cavity underground river of tunnel structure bottom, top and stablize on the basement rock.
In such scheme, the pneumatically placed concrete layer in the tunnel structure of described top is positioned at crag surface, tunnel, and system anchor bolt 3 is arranged in crag and is connected with the pneumatically placed concrete layer, and described secondary lining 2 is positioned at the pneumatically placed concrete laminar surface.
Preferably, be provided with backfill layer 6 above the arch ring of the bottom arch bridge bottom the tunnel structure of top, form roadbed.
Preferably, described bottom arch bridge adopts real abdomen formula arch bridge to cross over.
The utility model top tunnel structure separates setting with the bottom arch bridge, forms non-enclosed construction, and the top tunnel structure bears the country rock load separately, and the bottom arch bridge is crossed over solution cavity, underground river, bears train load.
This utility model has the following advantages with respect to background technology:
1) the top tunnel structure separates setting with the bottom arch bridge, and the each several part structure stress is clear and definite, the reliability height.
2) adopt real abdomen formula arch bridge to cross over easy construction, the settlement after construction of having avoided backfill to cause.
3) separate type has effectively reduced the load that acts on the real abdomen formula arch bridge, has reduced construction investment, has guaranteed operation security.
Description of drawings
Fig. 1 present embodiment schematic cross-sectional view;
Fig. 2 present embodiment longitudinal section schematic diagram.
The specific embodiment
Feature of the present utility model is described in further details by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Embodiment: this example relates to strides solution cavity, location, underground river supporting and protection structure on the tunnel, be mainly used in tunnel and underground engineering field, and it mainly is made up of the real abdomen formula of top tunnel structure and bottom arch bridge:
1) described top tunnel structure is made of pneumatically placed concrete layer 1, secondary lining 2, system anchor bolt 3, bears top country rock load.Pneumatically placed concrete layer 1 in the tunnel structure of top is positioned at crag surface, tunnel, and system anchor bolt 3 is arranged in crag and is connected with pneumatically placed concrete layer 1, and secondary lining 2 is positioned at the pneumatically placed concrete laminar surface.
2) the real abdomen formula in described bottom arch bridge by longitudinal load-bearing structure arch bridge arch ring 4, be positioned at 7 both sides, solution cavity underground river and stablize the arch bridge abut 5 on the basement rock, arch bridge backfill layer 6 (bridge floor) formation of train driving, train load is passed on the arch bridge abut 5 that is positioned at solution cavity underground river 7 both sides basement rock by arch bridge backfill layer and arch bridge arch ring.
The utility model structure stress is clear and definite, structure is succinct, easy construction, reliability height, can avoid settlement after construction that backfill may cause and to underground Effects of water environment.
Claims (4)
1. stride location, solution cavity underground river supporting and protection structure on the tunnel, comprise top tunnel structure and bottom arch bridge, it is characterized in that: described top tunnel structure is the non-enclosed construction on corresponding solution cavity underground river, bottom, is made of pneumatically placed concrete layer (1), secondary lining (2), system anchor bolt (3); Described bottom arch bridge is positioned on the solution cavity underground river of tunnel structure bottom, top, is made of arch ring (4), abut (5), and described arch ring arranges vertically that along the tunnel two ends are positioned at the both sides, solution cavity underground river (7) of tunnel structure bottom, top and stablize on the basement rock.
