Abstract
The utility model relates to a balanced drain system in tunnels. The water displacements of side drain ditches on two sides of the tunnel as well as those of two bidirectional tunnels are different, and the drain effect is influenced when the water displacements are balanced. The side drain ditches are respectively dug on two sides of the bottom of the tunnel, and are communicated through a plurality of inclined underground drain pipes between the side drain ditches; an inclined contact channel is arranged between the two bidirectional tunnels; a side contact channel ditch is dug on one side of the bottom of the contact channel; the underground drain pipe between the tunnels is buried at the bottom of the contact channel; the side drain ditches which have the nearer distance in the two bidirectional tunnels are communicated through the underground drain pipe between the tunnels. The underground drain pipe is buried at the bottom of the tunnel, water in the side ditch with large water displacement is introduced into a side ditch with small water displacement, meanwhile, the underground drain pipe is buried at the bottom of the contact channel to balance drain of the two tunnels and ensure smooth drain of the tunnels; the balanced drain system has the advantages of being simple in investment, saving investment, being safe and reliable and the like.
Description
Technical field
the utility model belongs to tunnel traffic field of engineering technology, is specifically related to balanced drainage system in a kind of tunnel.
Background technology
The traffic engineering such as China railways, highway has been built a large amount of construction of tunnel, the area of growing at some underground water, and after tunnel builds up operation, water yield is very large, need to carry out permanent draining by ditch in tunnel.Generally adopt the mode that gutter is set in both sides to carry out permanent draining, current fair line road longitudinal gradient direction, by the high-end low side that flows to, finally flows out outside tunnel.Owing to limited by tunnel cross-section, conventionally ditch, both sides cross dimensions is identical, if it is more balanced or be less than ditch drainability that both sides, tunnel enter the underground water in ditch, can not affect use, but often because factor impacts such as the paths of underflow, enter the water yield difference in ditch, both sides, especially some long tunnels, construction period is provided with the service galleries such as inclined shaft in a side, water outlet in tunnel can only flow in a lateral sulcus, therefore, cause the medial sulcus one side water yield in tunnel large, a side water yield is very little.And for two parallel tunnels, the phenomenon that in a tunnel, in large another tunnel of the water yield, the water yield is little is common especially.When wherein ditch water yield is excessive while exceeding its drainability, the flow of water must be overflowed and be caused disease, and other ditch does not play a role.
Summary of the invention
The purpose of this utility model is to provide balanced drainage system in a kind of tunnel, by hidden pipe is set between ditch, makes each ditch mutual balanced displacement of energy in the situation that the water yield is different, ensures that tunnel drainage is unimpeded.
The technical scheme that the utility model adopts is:
Balanced drainage system in a kind of tunnel, respectively digs and puts a draining lateral sulcus in the inner side of the both sides of tunnel bottom, two cable trenchs, it is characterized in that:
Between the draining lateral sulcus of both sides, be communicated with by closed drain between some oblique draining lateral sulcus, between draining lateral sulcus, the direction of burying underground of closed drain is along circuit longitudinal gradient direction of fall from high to low;
Between two-way two tunnels, be provided with oblique service channel, service channel bottom one side is dug and is put a service channel lateral sulcus, service channel lateral sulcus bottom is embedded with closed drain between tunnel, in two-way two tunnels, the drain-side ditch of close together is communicated with by closed drain between tunnel, between tunnel closed drain bury underground direction be circuit longitudinal gradient direction of fall from high to low.
The utlity model has following advantage:
The utility model is by burying closed drain underground at tunnel bottom, water in the lateral sulcus large water yield is introduced in the lateral sulcus that the water yield is little, simultaneously, by burying closed drain underground in service channel bottom, the draining in balanced two tunnels, hidden pipe quantity is determined according to displacement flexible in size, make Nei Getiao ditch, tunnel in the situation that the water yield is very large, all can bring into play drainage, to ensure that tunnel drainage is unimpeded, can not cause harm influence safety, have construction simple, reduce investment outlay, the plurality of advantages such as safe and reliable.
Brief description of the drawings
Fig. 1 is the utility model sectional drawing.
Fig. 2 is the utility model plan view.
In figure, 1-cable trench, 2-draining lateral sulcus, 3-service channel, 4-service channel lateral sulcus, closed drain between 5-tunnel, closed drain between 6-draining lateral sulcus.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
Balanced drainage system in the related a kind of tunnel of the utility model is the form of structure of both sides lateral sulcus in the same seat of a kind of equilibrium tunnel and parallel two tunnel ditch drainabilities.Not changing on the basis of tunnel cross-section size and structural configuration, make full use of current conditions, existing utility is performed to maximum effect.
In a tunnel, respectively dig and put a draining lateral sulcus 2 in the inner side of the both sides of tunnel bottom, two cable trenchs 1, between the draining lateral sulcus 2 of both sides, be communicated with by closed drain 6 between some oblique draining lateral sulcus, between draining lateral sulcus, the direction of burying underground of closed drain 6 is along circuit longitudinal gradient direction of fall from high to low, to ensure that between draining lateral sulcus, closed drain 6 has minimum drainage grade, water (flow) direction is that the lateral sulcus that the water yield is large flows to the lateral sulcus that the water yield is little, therefore, closed drain 6 right-to-left or from left to right as required between draining lateral sulcus.Between draining lateral sulcus, closed drain 6 is PVC hard plastic tube, can be according to actual amount of water situation quantification.
For two parallel tunnels, between two-way two tunnels, be provided with oblique service channel 3, service channel 3 bottom one sides are dug and are put a service channel lateral sulcus 4, service channel lateral sulcus 4 bottoms are embedded with closed drain 5 between tunnel, in two-way two tunnels, the draining lateral sulcus 2 of close together is communicated with by closed drain between tunnel 5, between tunnel closed drain 5 bury underground direction be circuit longitudinal gradient direction of fall from high to low, water (flow) direction is that tunnel flow that the water yield is large is to the little tunnel of the water yield.Closed drain 5PVC hard plastic tube between tunnel, can be according to actual amount of water situation quantification.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skill in the art take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
