Abstract
The utility model relates to a bored decompression side-ditch centralized drainage structure for a traffic tunnel, and belongs to traffic tunnels. A tunnel arch drainage channel is fixedly communicated with drainage side ditches; a concrete bottom drainage blind ditch is fixedly communicated with the drainage side ditches; the drainage side ditches are covered with reinforced concrete cover plates; plastic drainage blind ditches for surrounding rocks at the lower part of the tunnel are fixedly communicated with the drainage side ditches; and the included angles between the plastic drainage blind ditches for the surrounding rocks at the lower part of the tunnel and a plumb line direction is alpha, which is 10 degrees. The bored decompression side-ditch centralized drainage structure has the advantages that the bored decompression side-ditch centralized drainage structure is novel in structure, capable of removing underground confined water of the traffic tunnel effectively, simple in construction process, short in construction period, convenient and fast in construction method, clear in principle, easy to master, and suitable for traffic tunnels of various types on roads of II level or lower than II level, so as to be a new breakthrough of the design of drainage facilities for the traffic tunnel.
Description
Technical field
The utility model belongs to traffic tunnel, especially the traffic tunnel discharge structure on the highway.
Background technology
Because traffic tunnel passes through massif or imbeds underground; Phreatic activity makes tunnel surface get damp, seep water, freeze; This phenomenon not only makes tunnel lining concrete produce calcium loss and freeze-thaw damage, influences tunnel application life, and traffic safety is brought serious hidden danger.
For the transport solution tunnel gets damp, infiltration, ice formation issues, in the design and construction of traffic tunnel, the normal employing is provided with central buried gutter and gets rid of the underground water in the rock mass.This method system enters central buried gutter with the underground water in the rock mass through transverse drain, concentrates through the buried gutter of central authorities to be discharged to the outer highway gutter of traffic tunnel to underground water again.But it is comparatively complicated that shortcoming is a construction technology, and construction costs is high, and the construction period is longer.Though the excavated volume of central buried gutter own is also little, for rock excavation, channel excavation can be wasted the more time, and in digging process, need take the controlled blasting measure, otherwise will destroy the groove surrounding rock body.In case rock mass goes to pot, just must fractured rock be excavated, and adopt concrete to carry out backfill, can increase more investment like this.Just can carry out the construction on road surface after accomplishing central buried gutter and transverse drain simultaneously, influence the construction period, and for ease of maintenance, require at certain distance manhole to be set, manhole is also influential to traffic safety.
Summary of the invention
The utility model provides a kind of traffic tunnel boring decompression gutter centralized discharge structure, and to solve present traffic tunnel drainage construction complex process, construction costs is high, and the construction period is long, and the problem of well to the traffic safety influence that detect is set.
The technical scheme of the utility model is: arch, tunnel drainage channel fixedly is communicated with gutter; The concrete base weeper drain fixedly is communicated with gutter; Cover the steel concrete cover plate above the gutter; Bottom, tunnel country rock water drainage plastics french drain fixedly is communicated with gutter, and bottom, tunnel country rock water drainage plastics french drain and plumb line angular separation are α, and the α angle is 10 °.
The advantage of the utility model is: novel structure; The underground artesian water that can get rid of traffic tunnel effectively; And construction technology is simple, save the construction period, job practices is convenient, clear principle, easy master, applicable to II level and II level with the various forms of traffic tunnels on getting down the highway.It is the new breakthrough of traffic tunnel drainage design.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Arch, tunnel drainage channel 2 fixedly is communicated with gutter 1; Concrete base weeper drain 3 fixedly is communicated with gutter 1; Cover steel concrete cover plate 5 above the gutter 1; Bottom, tunnel country rock water drainage plastics french drain 4 fixedly is communicated with gutter 1, and bottom, tunnel country rock water drainage plastics french drain 4 is α with the plumb line angular separation, and the α angle is 10 °.
In conjunction with walkway, both sides, traffic tunnel road surface or maintaining roadway, gutter is set below it as main drainage channel.Gutter is arranged to have certain longitudinal grade, so that get rid of surface gathered water and guarantee that water does not freeze under flow regime.Cover the steel concrete cover plate above the gutter, be convenient to pedestrian or maintainer walking.Drainage channel gutter below the sidewalk in arch, tunnel links to each other, and underflow around the hogback is gone into to gutter, finally is rejected to outside the tunnel.Be exuded to pavement concrete bottom underground water,, underground water be incorporated into the both sides gutter, be discharged to outside the tunnel again through burying the method for concrete base weeper drain underground.Weeper drain is arranged to have certain longitudinal gradient, and pavement concrete bottom artesian water just can be drained in the gutter smoothly like this.The mode that bottom, tunnel country rock artesian water adopts rig to beat drain hole drains in the gutter, both sides underground water.Plug is filled out the plastic draining french drain in the hole, prevents the drain hole obstruction and reduces seepage pressure.Descend artesian water just can well be drained in the gutter of both sides in this wise, can play good effect the generation that solves road surface counter tide, the phenomenon of freezing along the plastic draining french drain.
Claims (2)
1. the centralized discharge structure of traffic tunnel boring decompression gutter; Arch, tunnel drainage channel fixedly is communicated with gutter; The concrete base weeper drain fixedly is communicated with gutter; Cover the steel concrete cover plate above the gutter, bottom, tunnel country rock water drainage plastics french drain fixedly is communicated with gutter, it is characterized in that: bottom, tunnel country rock water drainage plastics french drain and plumb line angular separation are α.
2. according to the centralized discharge structure of claim 1 said traffic tunnel boring decompression gutter, it is characterized in that: the α angle is 10 °.
