Abstract
The utility model relates to a tunnel structure that has adverse slope near water. The utility model aims at providing a tunnel structure that has adverse slope near water aims at preventing through simple, practical, effectual structure that the flood from flowing backward the entrance to a cave to improve the degree of safety of tunnel construction and operation in -process. The utility model provides a: a tunnel structure that has adverse slope near water, this tunnel of includes the adverse slope section, arranges that a plurality of roots are used for the drain pipes of pump drainage percolating water and waste water, are equipped with catch water drain, its characterized in that below the drain pipe between the bottom plate of adverse slope section and one side hole wall: set up one section in the import department of tunnel and link up in the same direction as the slope section and with the adverse slope section, should in the same direction as the slope section corresponding to the apron culvert box formula that the is equipped with escape canal of the position of catch water drain, the escape canal is connected with the water treatment pond of establishing outside the tunnel. The utility model is suitable for a tunnel import is arranged and is probably being suffered water level influence areas such as rivers, coombe, and synthesizes the tunnel engineering that the slope is the adverse slope.
Description
Technical field
The utility model relate to a kind of near water, there is the tunnel structure of adverse slope.Mainly be applicable to tunnel import be arranged in and may suffer the water level such as rivers, coombe influence area, and the comprehensive gradient is the tunnel engineering of adverse slope.
Background technology
Underground construction, due to the restriction by the factor such as geological conditions and adjoining rock stability, often buried depth is larger, the discrepancy in elevation apart from earth's surface is corresponding larger, towards all kinds of tunnels of underground construction, as access tunnel, working tunnel, ventilation hole, cable hole, passway for escaping, drainage tunnel etc., major part can only take adverse slope to design.Adverse slope tunnel often can relate to the problem of two aspects, and one is flood control problem, and hole is arranged and will be taken into full account not by big vast water mitigation, and super standard flood also will be prevented to pour in down a chimney hole.If generation flood backflush, the personnel in underground construction, equipment will all be submerged, consequently catastrophic.Two is drainage reasonable Arrangement problems, and the waste water etc. in the percolating water in tunnel and construction, running will adopt lays flowing line, power pump drainage to outside hole.Due to limited space in tunnel, allly assign traffic for the numerous pipeline such as airduct, air chimney and operation brings potential safety hazard in gutter, feed pipe, cable, high pressure, particularly tunnel inducer, pilot's line of vision environment is by bright dimmed, careless slightly, will to collide, pipeline that swipe ground and Dong Bi lay.The flowing line that the good caliber of reasonable Arrangement is larger, greatly will improve security reliability.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, there is provided a kind of near water, there is the tunnel structure of adverse slope, be intended to prevent flood backflush hole by simple, practical, effective structure, and improve the degree of safety in tunnel construction and running.
The technical scheme that the utility model adopts is: a kind of near water, there is the tunnel structure of adverse slope, this tunnel comprises adverse slope section, the some gutters for pump drainage seepage water and waste water are furnished with between the base plate and hole, side wall of adverse slope section, collecting gutter is provided with below gutter, it is characterized in that: arrange one section in the import department of tunnel and be connected along slope Duan Bingyu adverse slope section, this along slope section correspond to described collecting gutter position be provided with the box gutter of slab culvert, gutter is connected with the water treating pond be located at outside tunnel.
The described end elevation along slope section is more than or equal to the elevation of tunnel mouth check flood level, and this gradient along slope is 0.5% ~ 3%.
Described drain level is arranged side by side on tunnel base plate or vertical array is affixed on hole wall, and gutter securing member and base plate or hole wall are fixed.
The beneficial effects of the utility model are: the utility model is maintaining under the prerequisite that underground construction integrated planning design scheme is constant, construction investment does not increase, by improving tunnel inducer structure, both avoid flood backflush and enter hole, enhance flood control capacity, the safety be significantly increased in construction and running.

Fig. 1 is longitudinal plan of the present utility model.
Fig. 2 is of the present utility model along slope section drawing in side sectional elevation.
Fig. 3 is adverse slope section drawing in side sectional elevation of the present utility model.
Detailed description of the invention
Plan as a whole to determine hole floor elevation according to the data such as result of design, hydrological data, geologic information, hole site condition, hole connection highway arrangement condition of underground construction integrated planning.Hole floor elevation is not less than design flood level, if hole floor elevation reaches or higher than check flood level, also can consider that the rainwater that Tunnel slope and place are watched out in one section of suitable slope pours in down a chimney.
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment be a kind of near water, there is the tunnel structure of adverse slope, this tunnel comprises adverse slope section 2 and one section of suitable slope section 1 being arranged on tunnel import department and being connected with adverse slope section 2, and for airduct 8 and feed pipe 9, and air chimney 10 is set with reasonable Arrangement illuminating line 6, cable 7, high pressure on hole, the side wall along slope section 1 at the top of tunnel in the adverse slope section 2 of tunnel.Many gutters 4 are arranged between the base plate of adverse slope section 2 and hole, side wall, and for pump drainage seepage water and waste water, gutter 4 horizontal Tile is arranged on tunnel base plate or vertical array is affixed on hole wall, and fix with securing member and base plate or hole wall; Collecting gutter 5 is arranged on the below of gutter 4, and correspond to along slope section 1 this collecting gutter position be provided with the box gutter 3 of slab culvert, gutter is connected with the water treating pond be located at outside tunnel.
According to the discrepancy in elevation appropriate design of design flood level and check flood level along the length of slope section 1 and the gradient, the gradient generally gets about 3%, but should not be less than 0.5%; The length of adverse slope section 2 and the determination of the gradient depend primarily on the integrated planning design of tunnel; Adverse slope section 2 and suitable slope section 1 joining place, gutter 4 changes gutter 3 into, and the size in this gutter is according to the design of prediction drained strength, consider a certain proportion of nargin, and adopting slab culvert box, cover plate can pressure-bearing, and load capacity calculation must meet plant equipment safety in tunnel.By the selection of the caliber and radical etc. of the discharge capacity of the seepage water and waste water of prediction and calculation underground construction, collecting well (sump) scale, drainage pump model, gutter 4, stand by pump need be configured.
The operating principle of the present embodiment: the seepage water and waste water of underground construction, adverse slope section 2 and the intersection along slope section 1 is pumped to by kinetic pump through gutter 4 from collecting well (sump), then change drainage pattern into gutter along slope draining from power pump drainage, namely pass through gutter 3 along slope draining to outside tunnel.
