Abstract
The utility model relates to an enclosed concrete windproof open cut tunnel for strong wind areas. The traditional wind-shield structure generally adopts wind-shield walls having certain heights and arranged on two sides of a roadway, and can reduce the influence of external environment on vehicles between the wind-shield walls while having the defects that the effect is not obvious and the sand accumulation phenomenon is serious. The enclosed concrete windproof open cut tunnel is characterized in that two rows of pile foundations are arranged along a line, pile top longitudinal beams are arranged along the line on the pile tops of the two rows of pile foundations; an arched reinforced concrete lining structure is arranged between and above the pile top longitudinal beams; and ventilation and daylighting holes are formed in the arched part and the side wall on the leeward side of the reinforced concrete lining structure. The enclosed concrete windproof open cut tunnel has good sandstorm abrasion resistance and small operation and maintenance workload, and can relatively isolate the external environment from the driving environment so as to prevent the both from influencing each other; and the arranged ventilation and daylighting holes achieve the purposes of natural ventilation, natural daylighting and improvement on the in-tunnel driving environment.
Description
Technical field
The utility model belongs to the traffic engineering technical field, is specifically related to the windproof open cut tunnel of the closed concrete in a kind of strong wind district.
Background technology
In the strong wind area, like the Bai Lifeng district and the three Shi Lifeng districts in Xinjiang, its core space not only wind-force is powerful, and the frequency height of strong wind occurs.The Lan-xing Railway second two-wire passes famous Bai Lifeng district, three Shi Lifeng districts, and its wind-force is powerful, and maximum wind velocity reaches 60m/s; The annual strong wind fate greater than strong gale in Bai Lifeng district was above 200 days; Windburn is very serious, in order to guarantee train safe, quick, normal operation, reduces speed limit to greatest extent and stops wheel; Need be with the relative isolation of external environment and environment, thus the environment and the external world are independent of each other.Traditional wind shielding structure generally is employed in the windbreak that the road both sides are provided with certain altitude, can make the external environment and the influence of driving within the walls that certain reducing arranged, but effect is not clearly, and long-pending sand phenomenon is serious on the contrary.
Summary of the invention
The purpose of the utility model provides a kind of windproof open cut tunnel of the closed concrete in strong wind district that environment is played protection effect at the environment sensitive section.
The technical scheme that the utility model adopted is:
The windproof open cut tunnel of the closed concrete in a kind of strong wind district is provided with the pile foundation of two row's road along the line directions, it is characterized in that:
The stake top of described every row pile foundation is provided with the stake top longeron of road along the line direction;
Top between the longeron of described stake top is provided with the reinforced concrete lining layer structure of arch.
The leeward side arch and the abutment wall of described reinforced concrete lining layer structure are provided with the ventilation and lighting hole.
The utlity model has following advantage:
The utility model anti-blown sand abrasion performance is good; The operation maintenance workload is little, and can be with the relative isolation of external environment and environment, and environment and the external world are independent of each other in the hole thereby make; Through numerical simulation analysis and wind tunnel model test; Under the extraneous wind speed of 50m/s～70m/s, the wind speed maximum wind velocity in the open cut tunnel is 9 m/s, and driving is not almost had influence; On the basis that does not influence structural safety and anti-dust storm effect, reach natural ventilation, natural lighting, improve the purpose of vehicle operating environment in the hole.
Description of drawings
Fig. 1 is the utility model cross section.
Fig. 2 is the utility model open cut tunnel leeward side side view.
Among the figure, 1-pile foundation, 2-stake top longeron, 3-roadbed body construction, 4-reinforced concrete lining layer structure, 5-leeward side haunch ventilation and lighting hole, 6-leeward side abutment wall ventilation and lighting hole.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
The windproof open cut tunnel of the closed concrete in the described a kind of strong wind of the utility model district road along the line direction is provided with, and the pile foundation 1 of two rows road along the line direction is set on the both sides of roadbed body construction 3, and spacing and road bed vehicle width and the device space require to adapt.The stake top of every row pile foundation 1 is provided with the stake top longeron 2 along road-trend.Top between the stake top longeron 2 is provided with the reinforced concrete lining layer structure 4 of arch, and promptly windproof open cut tunnel structure forms a kind of structural system of the relative isolation with external environment and environment.Open cut tunnel is the open structure that substrate does not have inverted arch or base plate; Road surface structure places on the road structure; The open cut tunnel basis can be adopted pile foundation or enlarge the basis according to strata condition, and the arch wall lining cutting is adopted cast-in-place or precast block reinforced concrete structure according to the site operation ambient conditions.The leeward side arch and the abutment wall of reinforced concrete lining layer structure 4 are provided with the ventilation and lighting hole; The leeward side arch be leeward side haunch ventilation and lighting hole 5; Abutment wall be leeward side abutment wall ventilation and lighting hole 6; These ventilation and lighting holes reach natural ventilation, natural lighting on the basis that does not influence structural safety and anti-dust storm effect, improve the purpose of vehicle operating environment in the hole.
