Abstract
The utility model relates to a cold existing tunnel in district concentrates the seepage to draw the dark groove of drainage among the tunnel disease treatment, its characterized in that: following tunnel vertical lining cutting side wall foot of a wall bottom and setting up the escape canal, set up the cable duct on escape canal upper portion, no. Two apron of adoption separate between escape canal and the cable duct, and the closed cable duct of apron is adopted no. One at the cable duct top, and during groundwater passed through transverse drainage bank of tubes income escape canal around the tunnel, cable duct and escape canal outside cell wall adopted the reinforced concrete structure one -piece casting, and inboard cell wall and secondary lining side wall are pour together. Adopt this kind of escape canal and cable duct to build the structure jointly, both satisfied the requirement of tunnel drainage, also provide effective space for the cable is current. The utility model discloses the structure has improved the efficiency of construction of tunnel escape canal, cable duct, has reduced the tunnel excavation space, and simple structure, the strong operability, and the cost is lower, clearance easy maintenance, simultaneously, interference to driving a vehicle in the tunnel in the time of can reducing the mediation clearance.
Description
Technical field
The utility model relates to highway tunnel and builds middle a kind of drought-hit area highway tunnel cable channel and gutter global design structure.
Background technology
In highway tunnel construction, cable channel and gutter are two requisite components, and tunnel drainage ditch and cable channel are the important component parts of tunnel waterproof and water drainage system and electric power, communication system.Tunnel cable groove is the concrete pit placing power cable, Capacitance Unbalance in Telecom Cables in construction of tunnel, be arranged at both sides, tunnel, side, general tunnel is signal of communication (light current) cable channel, opposite side is electric power (forceful electric power) cable channel, and it has better effects to the protection of cable in the shielding interference of control cables and heavy corrosion environment.The discharge of underground water around highway tunnel, gutter generally adopts central row ditch to carry out draining, to be generally positioned at below tunneled central inverted arch or above, to be drained into outside hole by underground water around tunnel.
In China's new highway tunnel, the gutter in major part tunnel and cable channel are separately design, construction, generally gutter is arranged and tunneled central, central drainage pipe decapacitation is drained outside the water of lining cutting behind preferably, at the bottom of tunnel, the circulating pathway of underground water is shorter simultaneously, water at the bottom of tunnel also can comparatively directly fast be pooled in central drainage pipe, accomplishes that draining is smooth and easy.Gutter is arranged at the tunnel of tunneled central for Sui Zhi district rich groundwater, has the advantage that it is certain.But gutter be arranged at central authorities because of vertical, horizontal gutter all need before building secondary lining concrete blasting base rocks fluting install, otherwise excavate time fragile secondary lining.So after vertical, horizontal gutter builds, in hole, the big machinery of subsequent construction ground thereon, easily damaged gutter by pressure and caused and do over again.For avoiding gutter to be damaged by pressure by large-scale construction equipment in subsequent construction, also can first excavate trench backfill and abandoning quarrel, not burying gutter, excavate again during road surface to be onstructed to have filled out and abandon quarrel, vertical, horizontal gutter is installed, but this make construction complexity.Central drainage pipe needs after installing to backfill graded broken stone, and carries out compacting and just can carry out pavement construction in tunnel, and this backfill rubble, except more difficult compacting, also easily causes damaging by pressure of central drainage pipe in compacting process.Central drainage pipe easily blocks, and needs to arrange Central drain manhole and dredges gutter, clears up, and cleaning work must be passed through by interfere with vehicles, and cleaning work is more difficult to be carried out, and is also difficult to the handling safety ensureing constructor simultaneously.In addition, manhole place is set, often causes the planeness of road surface running vehicle to reduce, affect road-ability, produce larger noise.
In the arid area that underground water is comparatively deficient, the invisible increase working procedure of Central drain is set, causes unnecessary cost waste.Tunnel drainage ditch arranges and both sides, tunnel by the design, build jointly with cable channel, the two monobloc cast, the middle cover plate that adopts is separated, and lining cutting behind underground water directly introduces lateral sulcus by ring direction drainpipe, and lateral sulcus draining makes the lining cutting distance that water circulates in tunnel shorten dramatically behind, draining is straightforward, relative to the gutter arranged and below inverted arch, decrease the excavated volume in tunnel, construction is simple.During the drain cleaner of both sides, can cover plate be raised, clear up from cable side, do not affect traffic safety, avoid the setting of manhole, eliminate the hidden danger of hole, road surface groove.
This tunnel ditch, cable channel one-time-concreting molding structure, simplify working procedure, significantly reduce construction cost, improve workmanship.
Summary of the invention
The utility model object is for drought-hit area, the tunnel of Sui Zhi district underground water scarcity, provides a kind of gutter of simplification and cable channel to build structure jointly, thus reduces project scale, cost, reduces operating cost, has stronger action row simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drought-hit area highway tunnel cable channel and gutter global design structure, it is characterized in that: bottom the longitudinal lining side wall foundation in tunnel, gutter is set, on top, gutter, cable channel is set, No. two cover plates are adopted to separate between gutter and cable channel, cable channel top adopts a cover closure cable channel, around tunnel, underground water enters in gutter by transverse drain, outside cable channel and gutter, cell wall adopts reinforced concrete structure monobloc cast, inner side cell wall is built together with secondary lining abutment wall.
Adopt this gutter and cable channel to build structure jointly, both met the requirement of tunnel drainage, also provide the usefull space for cable is current.Improve the efficiency of construction of tunnel drainage ditch, cable channel, reduce tunnel excavation space, and structure is simple, strong operability, cost is lower, clears up easy to maintenance; Meanwhile, can reduce when dredging is cleared up the interference of driving a vehicle in tunnel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structural representation of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: the cell wall 7-secondary lining abutment wall 8-transverse drain of cell wall 6-inner side, No. 3-one, 1-cable channel, 2-gutter cover plate 4-No. two cover plate 5-outsides.
Detailed description of the invention
With reference to accompanying drawing, a kind of drought-hit area highway tunnel cable channel and gutter global design structure, it is characterized in that: bottom longitudinal lining side wall (7) foundation in tunnel, gutter (2) is set, on gutter (2) top, cable channel (1) is set, No. two cover plates (4) are adopted to separate between gutter (2) and cable channel (1), cable channel (1) top adopts a cover plate (3) to close cable channel (1), around tunnel, underground water enters in gutter (2) by transverse drain (8), cable channel (1) and gutter (2) outside cell wall (5) adopt reinforced concrete structure monobloc cast, inner side cell wall (6) and secondary lining abutment wall (7) are built together.
operating principle
Underground water in the country rock of lining cutting behind enters gutter by transverse drain, enters gutter without inverted arch tunnel bottom underground water by gutter cell wall spilled water hole.By cover plate by gutter and cable channel segmentation, erecting cable in cable channel, to realize the two respective function.
