Abstract
The utility model relates to a natural lighting type windproof opencut tunnel lining structure. The natural lighting type windproof opencut tunnel lining structure is used for solving the problems that not only is the cost of construction equipment increased, but also the operating cost is high caused by the fact that a tunnel portal of a closed windproof structure arranged on a roadbed of a wind zone is provided with a buffer and pressure relief structure when conditions exist. The natural lighting type windproof opencut tunnel lining structure is provided with an opencut tunnel lining body, wherein the opencut tunnel lining body is formed through splicing an opencut tunnel arch portion and opencut tunnel side walls at the two sides of the opencut tunnel arch portion, round-end-shaped lighting and pressure relief holes are formed in the opencut tunnel arch portion and the opencut tunnel side walls, and outwardly-oblique slope faces are formed on the lower edges of the lighting and pressure relief holes; and the longitudinal spacing of the lighting and pressure relief holes is 3m, the size of the lighting and pressure relief holes of an arch waist is 1.2m*0.8m, and the size of the lighting and pressure relief holes of the side walls is 1.0m*0.6m. The natural lighting type windproof opencut tunnel lining structure is provided with the lighting and pressure relief holes with reasonable positions, shapes and sizes, the safety and wind and sand proofing effects of the structure are not affected, and the aims of natural lighting, natural ventilation and aerodynamic effect reduced pressure relief can be realized, so that the low-carbon and energy-saving effects are reached, and the construction and operation costs are reduced effectively.
Description
Technical field
The utility model belongs to the traffic engineering technical field, is specifically related to the windproof open cut tunnel liner structure of a kind of natural lighting type.
Background technology
The Lan-xing Railway second two-wire passes famous Bai Lifeng district, three Shi Lifeng districts, its core space not only wind-force is powerful, and the frequency height of strong wind appears, in order to guarantee train safe, quick, normal operation, reduce speed limit and stop wheel, be provided with the windproof structure of sealing at roadbed, can solve an above-mentioned difficult problem effectively, but general railway tunnel (or open cut tunnel) need arrange fixedly repairing lighting when length 500m is above, the buffering pressure relief when having ready conditions, the hole is set, not only increase and build equipment cost, and operation cost is also high.
Summary of the invention
The purpose of this utility model provides a kind of windproof open cut tunnel liner structure of natural lighting type that can reach natural lighting, effect of natural ventilation.
The technical scheme that the utility model adopts is:
The windproof open cut tunnel liner structure of a kind of natural lighting type is provided with the open cut tunnel lining cutting body on the roadbed body that places the strong wind district, and open cut tunnel lining cutting body is spliced by the open cut tunnel abutment wall of open cut tunnel arch and both sides, open cut tunnel arch, it is characterized in that:
Be provided with the daylighting relief hole of nose circle shape on described open cut tunnel arch and the open cut tunnel abutment wall, it is domatic that daylighting relief hole lower edge is provided with outward-dipping daylighting relief hole lower edge.
The longitudinal pitch of described daylighting relief hole is 3m, and wherein haunch daylighting relief hole is of a size of 1.2m * 0.8m, and abutment wall daylighting relief hole is of a size of 1.0m * 0.6m.
The utlity model has following advantage:
Position, shape, the rational daylighting relief hole of size are set on the closed windproof open cut tunnel described in the utility model, do not influence structural safety and anti-dust storm effect, can realize natural lighting, natural ventilation and reduce the purpose of the pressure release of aerodynamic effects, reached the low-carbon energy-saving effect, effectively reduced and build and operation cost.
Description of drawings

Fig. 2 is the utility model lateral view.
Fig. 3 is daylighting relief hole structure chart.
Among the figure, 1-open cut tunnel lining cutting body, 2-roadbed body, 3-open cut tunnel arch, 4-open cut tunnel abutment wall, 5-haunch daylighting relief hole, 6-abutment wall daylighting relief hole, 7-daylighting relief hole lower edge is domatic.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in detail.
The windproof open cut tunnel liner structure of a kind of natural lighting type that the utility model is related, under the prerequisite of guaranteeing open cut tunnel structural safety and protection effect, offer position, shape, the rational hole of size at the open cut tunnel barrel, realize natural lighting, natural ventilation and reduce the purpose of the pressure release of aerodynamic effects, reached the low-carbon energy-saving effect.
Open cut tunnel lining cutting body 1 is spliced by the open cut tunnel abutment wall 4 of open cut tunnel arch 3 and 3 both sides, open cut tunnel arch, be provided with the daylighting relief hole of nose circle shape (two ends semicircle middle part rectangle) on open cut tunnel arch 3 and the open cut tunnel abutment wall 4, it is domatic 7 that daylighting relief hole lower edge is provided with outward-dipping daylighting relief hole lower edge, and anti-falling stop sand enters open cut tunnel.The longitudinal pitch of daylighting relief hole is 3m, wherein haunch daylighting relief hole 5 is of a size of 1.2m * 0.8m(height * wide), abutment wall daylighting relief hole 6 is of a size of 1.0m * 0.6m(height * wide), reach natural lighting in the hole, natural ventilation and reduce the purpose of the pressure release of aerodynamic effects.
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 skills take technical solutions of the utility model by reading the utility model manual is claim of the present utility model and contains.
