Description
Technical field
The utility model belongs to tunnel groove technical field, specifically, relates to a kind of merging groove containing tunnel cable groove and roadside drainage ditch.
Background technology
China's rapid development of economy brings the traffic volume to be increased significantly, the leakage problem of highway tunnel more and more highlights, in operation tunnel, the situation that cable trench ponding or centre drain impeded drainage are difficult to again keep in repair often has generation, is necessary to be optimized design and necessary improvement to this situation.
The drainage system of tunnel internal is a complicated system engineering, and traditional tunnel drainage system roughly can be divided into two parts, and a part is that tunnel road surface and lining cutting seepage form " open fire ", is generally discharged by the gutter be arranged on both sides of the road; Another part is tunnel lining behind " dark water ", and the centre drain generally by being arranged on below in road is discharged.Tunnel lining Drainage Design behind adopts the form of centre drain usually, there is certain defect in this design, in the liner structure establishing inverted arch, the existence of centre drain can make the cast of inverted arch not carry out simultaneously, downward excavation is needed again when not establishing inverted arch, the globality of inverted arch or foundation structure will be destroyed like this, be unfavorable for the stable of tunnel support structure.Meanwhile, centre drain position is in below in the middle part of road surface, occurs that the maintenance after the problems such as blocking can be more difficult.
Tunnel internal cable trench is generally arranged on the both sides of tunnel carriage way, and wherein, the inner side of direction of traffic arranges strong cable channel, arranged outside weak cable groove.Cable run is arranged on the support of cable channel cell wall, be welded into a whole with galvanized flat steel between cable bearer, and be welded into a whole with power pipe outside pre-buried copper pipe, tunnel in tunnel, ensure electrical grounding path, in, in long tunnel, weak cable groove inside also can arrange fire protection pipeline, and pipeline is fixed on cell wall by support equally.Because the defects such as tunnel drainage system impeded drainage or tunnel structure crack cause the situation of tunnel internal percolating water to happen occasionally, it is smaller that cable channel inner drainage channel is often arranged, self dewatering needs can not be met, in factual survey process, just there is the situation that cable channel internal water accumulation too much jeopardizes groove inner cable facility.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of simple, unobstructed merging groove containing tunnel cable groove and roadside drainage ditch.
A kind of merging groove containing tunnel cable groove and roadside drainage ditch described in the utility model, described merging groove digs in the concrete wall 1 of road both sides, and it is divided into cable at vertical direction and lays district 2, central strip district and 3 three sections, catchment; Described cable is laid district 2 and be provided with cable bearer 5 on its cell wall, is provided with lamina tecti 4 above it, thereunder connects central strip district; The splash guard 7 that described central strip district comprises the cover plate 6 on upper strata, the corner of the geotextiles 8 of lower floor and centre is turned up; Described catchment 3 is positioned at below central strip district, the horizontal aqueduct 9 after its cell wall is provided with and stretches to tunnel lining.
A kind of merging groove containing tunnel cable groove and roadside drainage ditch described in the utility model, the seam crossing of described cover plate 6 is provided with the cover plate puncture 10 running through splash guard and geotextiles.Cover plate puncture is utilized to make catchment, bottom realize discharging the function of cable channel ponding.
A kind of merging groove containing tunnel cable groove and roadside drainage ditch described in the utility model, described cover plate puncture 10 establishes one every 25m.
A kind of merging groove containing tunnel cable groove and roadside drainage ditch described in the utility model, described lamina tecti 4 and cover plate 6 adopt lightweight hard plastic or plank.
