Abstract
The invention discloses a level linear highway tunnel with a drainage system. The longitudinal section of the highway tunnel is level and linear, and two ends of the highway tunnel are connected with a highway outside the tunnel. In-tunnel collector wells are disposed on two sides of the level linear highway tunnel every 10-30m, outer siphon balance collector tanks are reserved on two sides of the highway outside the tunnel and at two ends of the tunnel, the outer siphon balance collector tanks and the in-tunnel collection wells are equal in height, the outer siphon balance collector tanks on the same side of the highway tunnel are connected with the in-tunnel collector wells sequentially through siphons, the top of each of the outer siphon balance collector tanks and the in-tunnel collector well is covered with a drain plate, the lateral wall of each outer siphon balance collector tank is provided with a collector tank water level control hole, and the siphons are buried under the road surface in the tunnel. The level linear highway tunnel with the drainage system can meet the requirement that water in the tunnel is drained out timely, and solves the problems of low construction efficiency, lowered driving safety, unsmooth operation ventilation and the like caused by longitudinal slopes.
Description
Technical field
The present invention relates to the highway tunnel water discharge technology, relate in particular to a kind of straight linear highway tunnel with drainage system.
Background technology
At present; Stipulate in the highway in China Tunnel Design standard; The minimum value of vertical alignment in the tunnel (longitudinal gradient) should be built up back hole Nei Shui (comprise leak, water burst, infiltration etc.) with the tunnel and can drain naturally and be principle, and requirement must not be considered the constructing tunnel error again less than 0.3%; Generally preferably be not less than 0.3% ~ 0.5%, and (especially in western mountainous areas) longitudinal gradient often can meet or exceed 3% in the actual engineering.The design of longitudinal gradient tends to cause bad influence excessively suddenly: slag tap in (1) construction or the operating efficiency of transport of materials reduces; (2) influence driver's realization, reduce the safety and the comfortableness of vehicle '; (3) flue gas etc. is stuck in the tunnel top position of arching upward, and is unfavorable for circulation of air in the tunnel etc.
Summary of the invention
In order to improve the deficiency of traditional highway tunnel vertical alignment design; The invention provides a kind of straight linear highway tunnel with drainage system; The present invention not only can utilize dewatering installation to solve the stool problems of water in the hole, also can alleviate the harmful effect that existing vertical domatic design causes.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of straight linear highway tunnel with drainage system, the longitudinal cross-section of highway tunnel are straight linear, two ends all with the tunnel outside highway link to each other; Every separated 10-30 rice is provided with collecting well in the hole in straight linear highway tunnel both sides, and the both sides of highway are provided with siphon balance external collecting-tank respectively outside the tunnel at two ends; The collecting well elevation is suitable in siphon balance external collecting-tank and the hole; Collecting well links to each other through syphon successively in each siphon balance external collecting-tank of highway tunnel homonymy and the hole; Drainage plate all is stamped at the top of collecting well in siphon balance external collecting-tank and the hole; Have collecting-tank water level control hole on the siphon balance external collecting-tank sidewall, syphon is embedded under the road surface in tunnel.
The invention has the beneficial effects as follows, the present invention can be in satisfying the hole water in time drain appear outer in, solved problems such as the efficiency of construction that longitudinal gradient causes is low, travel safety reduces, the operation ventilation is not smooth.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified;
Fig. 1 is a usable condition sketch map of the present invention;
Fig. 2 is the longitudinal sectional drawing of the arrangement of Drainage of embodiment;
Fig. 3 is the A-A sectional drawing among Fig. 2
Fig. 4 is the domatic figure of the B-B among Fig. 2.
Collecting well 6, syphon 7, siphon balance external collecting-tank 8, drainage plate 9, collecting-tank water level control hole 10 in roadbed 1, country rock 2, road surface 3, soffit lining 4, vault lining cutting 5, the hole outside the tunnel.
The specific embodiment
Principle of the present invention is that the present invention designs the vertical alignment in the tunnel straight linear under the situation of landform and geological conditions permission; Both sides whenever are provided with collecting well in the hole across a certain distance in the tunnel, are convenient to that water flows into collection naturally in the hole; Outside tunnel portal the both sides, road surface respectively be provided with one with the hole in the suitable siphon balance external collecting-tank of collecting well elevation; With airtight syphon (diameter of pipe can be selected according to the seepage flow situation of locality) collecting well in all holes is linked to each other (when each collecting well elevation is suitable) successively, and be connected to collecting-tank outside the hole.Control water level outside the hole in the collecting-tank need suitably be lower than inside and outside road surface, hole, after the collecting-tank middle water level reaches control water level, will excrete outside the roadbed voluntarily.
As shown in Figure 1, highway tunnel of the present invention, its longitudinal cross-section is straight linear, two ends all with the tunnel outside highway link to each other.
As shown in Figure 2, whenever in straight linear highway tunnel both sides collecting well 6 in the hole is set at a distance from 10-30 rice, be convenient to that water flows into collection naturally in the hole; The both sides of highway are provided with siphon balance external collecting-tank 8 respectively outside the tunnel at two ends; Collecting well 6 elevations are suitable in siphon balance external collecting-tank 8 and the hole; Collecting well 6 links to each other through syphon 7 successively in each siphon balance external collecting-tank 8 of tunnel homonymy and the hole; Drainage plate 9 all is stamped at the top of collecting well 6 in siphon balance external collecting-tank 8 and the hole; Have collecting-tank water level control hole 10 on siphon balance external collecting-tank 8 sidewalls, syphon 7 is embedded under the road surface in tunnel.
Syphon 7 links to each other collecting well 6 in all holes successively, and is connected to the siphon balance external collecting-tank 8 of both sides.During syphon 7 initial installations, the mouth of pipe need exceed more than bottom 5 cm of collecting well 6 in siphon balance external collecting-tank 8 and the hole, prevents to suck deposit and stops up syphon.At first link to each other the syphon 7 in the siphon balance external collecting-tank 8 with vacuum pump; Afterwards collecting well 6 in siphon balance external collecting-tank 8 and the hole is filled with water to apart from after about the 20 ~ 30cm of road surface, vacuum pump is bled to make and is full of water in the syphon 7 to guarantee syphon 7 operate as normal.
Use the present invention, in the hole in water because of the road surface laterally in the middle of the arch camber spontaneous current go into collecting well 6 in the hole in roadside, when collecting well 6 middle water levels were higher than outside the hole siphon balance external collecting-tank 8 in the hole, water can pass through syphon 7 spontaneous currents to siphon balance external collecting-tank 8.Collecting-tank water level control hole 10 in the siphon balance external collecting-tank 8 is lower than road surface outside the hole, after siphon balance external collecting-tank 8 middle water levels reach control water level, excretes outside the roadbed voluntarily through collecting-tank water level control hole 10.
