Description
Technical field
The present invention relates to the flood control dash field of underground construction, specifically the uncovered ventilation section flood control water-retaining structure in a kind of tunnel and construction method thereof.
Background technology
Wear down in recent years and be positioned at scope lake, city institute built tunnel and often adopt cofferdam cut and cover tunneling, this construction method step is as follows: first, along enforcement cofferdam, both sides, tunnel (earth fill cofferdam or steel sheet-pile cofferdam etc.), drain lake water in cofferdam; Secondly in cofferdam, cut the earth and build tunnel, then earthing; Last backwater is removed recovery lake, cofferdam original appearance.The tunnel general rectangle multiple box culvert structure section form that adopts the method to build.
For long or super long tunnel, solving the long Distance Ventilation in tunnel is a difficult problem, its difficult point is there is higher view requirement engineering construction place for being positioned at, generally not allow to arrange high wind tower as tunnel ventilation facility, yet for guaranteeing that in tunnel, air quality must solve tunnel ventilation ventilation problem, solution is every certain distance, uncovered ventilation section to be set along length of tunnel preferably.For broad lake, waters, can in lake, in conjunction with manually filling island, the uncovered ventilation section in tunnel be set.As the tunnel of important traffic engineering, in lake, the flood level that uncovered ventilation section must consider to defend 100 years one chances or 300 years one chances is established in tunnel, so the uncovered ventilation section barricade in tunnel may be very high, affects island view.When being positioned at lake man-made island view, having relatively high expectations and consider that the uncovered ventilation section in tunnel builds short barricade when meeting view, how meeting tunnel safety Operational requirements in flood season, is urgent problem.
Summary of the invention:
The object of the present invention is to provide a kind of tunnel uncovered ventilation section flood control water-retaining structure, as the uncovered ventilation section in tunnel in the flood season dash of controlling flood temporarily, use, to meet tunnel safety Operational requirements in flood season.
To achieve these goals, technical scheme of the present invention is: the uncovered ventilation section flood control in a kind of tunnel water-retaining structure, it is characterized in that, on the uncovered ventilation section barricade in tunnel, the connected watertight shutter of polylith is installed, one side of every watertight shutter is provided with convex arc L-type rubber fastening band, opposite side is provided with concave arc L-type rubber fastening band, between two adjacent watertight shutters, by the convex arc L-type rubber fastening band coordinating, be connected with concave arc L-type rubber fastening band, in watertight shutter, be provided with a plurality of installing holes, described installing hole is equipped with the rubber O-ring seal coordinating with it, the outside of the uncovered ventilation section barricade in described tunnel is embedded with for the fastener inserts of watertight shutter is installed, described watertight shutter is connected with described fastener inserts by connecting bolt.Described fastener inserts is provided with connecting bolt, and this connecting bolt is through after the installing hole of watertight shutter, at the afterbody of this connecting bolt, sets gradually watertight rubber sheet, watertight rubber sheet pressing plate and nut.The bottom inside of described watertight shutter is provided with rubber fastening band, the edge of described rubber fastening band flushes with the corresponding edge of described convex arc L-type rubber fastening band and concave arc L-type rubber fastening band, and the inner side of described rubber fastening band and described convex arc L-type rubber fastening band and concave arc L-type rubber fastening band all fits tightly with the uncovered ventilation section barricade in tunnel.Described convex arc L-type rubber fastening band is fixed on a side of a watertight shutter in described two adjacent watertight shutters by convex arc L-type rubber fastening band pressing plate, described concave arc L-type rubber fastening band is fixed on the corresponding side with another watertight shutter by concave arc L-type rubber fastening band pressing plate, the outside of described convex arc L-type rubber fastening band is provided with an outer convex globoidal, and the outside of described concave arc L-type rubber fastening band is provided with the inner concave arc surface matching with described outer convex globoidal.Described convex arc L-type rubber fastening band and concave arc L-type rubber fastening band are equipped with distortion hole.
Another object of the present invention is to provide the construction method of the uncovered ventilation section flood control in a kind of tunnel water-retaining structure, at the uncovered ventilation section in tunnel in the flood season dash of controlling flood temporarily, use, to meet tunnel safety Operational requirements in flood season.
To achieve these goals, technical scheme of the present invention is: the construction method of the uncovered ventilation section in a kind of tunnel flood control water-retaining structure, is characterized in that the method comprises the following steps: A, in tunnel, uncovered ventilation section barricade outside is buried underground for the fastener inserts of watertight shutter is installed by precalculated position; B, polylith watertight shutter is connected with fastener inserts by connecting bolt, adjacent two watertight shutters are installed by the requirement that mutually combines of the corresponding female convex globoidal of convex arc L-type rubber fastening band and concave arc L-type rubber fastening band, the bottom inside of described watertight shutter is provided with rubber fastening band, and the inner side of described rubber fastening band and described convex arc L-type rubber fastening band and concave arc L-type rubber fastening band all fits tightly with the uncovered ventilation section barricade in tunnel.Wherein in step B, connecting screw rod is filled in the hole of described fastener inserts, the installing hole of described watertight shutter is provided with rubber O-ring seal, the described installing hole that is provided with rubber O-ring seal is through after this connecting screw rod, at the afterbody of connecting screw rod, puts successively watertight rubber sheet, watertight rubber sheet pressing plate and nut; Fastening nut after two mutual side direction of adjacent watertight shutter are compressed.
Be arranged in lake length or super long tunnel and establish the flood level that uncovered ventilation section must consider to defend 100 years one chances or 300 years one chances, therefore the uncovered ventilation section barricade in tunnel may be very high, affects island in lake (these island are built for the uncovered ventilation section in tunnel is set) view.When the island view that this is built is had relatively high expectations, as in tunnel, the very high barricade of uncovered ventilation section setting will affect island view for flood control, and consider that the uncovered ventilation section in tunnel builds short barricade and do not meet flood control requirement when meeting view, therefore in flood season, adopt mounting block water-bound wallboard on the uncovered ventilation section barricade in tunnel both can meet tunnel safety Operational requirements in flood season, can dismantle dash wallboard later in flood season again and meet view requirement.The invention has the advantages that on the uncovered ventilation section barricade in tunnel described water-retaining structure is installed, both can meet tunnel safety Operational requirements in flood season, can dismantle dash wallboard later in flood season again and meet view requirement.
