Abstract
The tunnel drainage structure that the utility model provides, comprises the longitudinal drainage pipe, transverse drain and the central drainage pipe that connect successively, and described transverse drain connects from expanding apart from central drainage pipe 30 centimeters to central drainage pipe, and expanding angle is 5-25 degree.The utility model is simple and reasonable for structure, by changing the cross-sectional area of current, namely changes lifting surface area, and reach and increase pressure object, the pressure of increase acts on crystalline solid, finally makes crystal depart from inner-walls of duct, is suitable for applying.
Description
Technical field
The utility model relates to a kind of tunnel drainage pipeline, belongs to technical field of drainage.
Background technology
In tunneling drain, calcareous crystalline polamer is mainly present in transverse drain, and from transverse drain end, gutter is blocked in crystallization.Tunneling drain calcareous Crystallization Plugging in limestone area is the engineering problem affecting tunnel drainage effect.Tunnel is through limestone area, because calcium carbonate crystal blocks gutter, long-term draining is obstructed very large on tunnel impact, constantly increase at tunnel outer hydraulic pressure, the supporting drag of tunnel support structure also increases thereupon, when after tunnel support structure cracking, tunnel there will be infiltration drainage in various degree, potential potential safety hazard is produced to the operation in tunnel, have a strong impact on the durability of tunnel structure, therefore researching and developing a kind of discharge structure that precipitation of calcium carbonate can be stoped to be attached to inner side tube wall, is necessary.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of tunnel drainage structure that precipitation of calcium carbonate can be stoped to be attached to inner side tube wall.
To achieve these goals, the utility model provides following technical scheme: a kind of tunnel drainage structure, comprise the longitudinal drainage pipe, transverse drain and the central drainage pipe that connect successively, described transverse drain is from expanding to this central drainage pipe apart from central drainage pipe 30 centimeters, and expanding angle is 5-25 degree.
As preferably, described expanding angle is 15 degree.
Can be found out by above technical scheme, the utility model is simple and reasonable for structure, by changing the cross-sectional area of current, namely change lifting surface area, reach and increase pressure object, the pressure of increase acts on crystalline solid, finally make crystal depart from inner-walls of duct, be suitable for applying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of transverse drain in the utility model;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of tunnel drainage structure as shown in Figure 1, comprise the longitudinal drainage pipe 1, transverse drain 2 and the central drainage pipe 3 that connect successively, described transverse drain 2 is from expanding to this central drainage pipe 3 apart from central drainage pipe 3 three ten centimeters, become expanding angle 4 to be 15 degree, described expanding angle 4 is the angle between former gutter excircle and the inclination conical surface, in exit, the bore of pipeline is done greatly, like this under the constant prerequisite of hydraulic pressure, increase the cross-sectional area of current, namely increase lifting surface area, reach the object increasing pressure.The pressure increased acts on crystalline solid, finally makes crystal depart from inner-walls of duct.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
Claims (2)
