Description
Technical field
This utility model relates to the road tunnel designing technique in municipal works technical field, concretely relates to the Impacts Evaluation of Urban Tunnel version of a kind of lateral open.
Background technology
Development along with urban construction, Impacts Evaluation of Urban Tunnel has obtained long term growth as a kind of traffic form, but when Impacts Evaluation of Urban Tunnel reaches certain scale, structure stress, ventilate, illuminate and Fire prevention etc. all becomes restriction road tunnel technology development and a difficult problem for engineer applied.
Conventional road tunnel design, by arranging the form such as blower fan, wind tower, reduces road tunnel inner exhaust gas pollution level, and local arranges passway for escaping, formulation escape and rescue scheme and rescue guiding facilities etc. and solves a Fire prevention difficult problem.But these structures and facility certainly will need extra land acquisition, though permanent wind tower structure can carry out building process, the most towering lofty, take the land resource of anxiety, blower fan, wind tower electricity consumption cause resource cost, these factors are often difficult to accept or reject when government's approval decisionmaking, cause being difficult to carry out of road tunnel engineering.
Utility model content
This utility model provides the Impacts Evaluation of Urban Tunnel version of a kind of lateral open, it is possible to effectively solves Impacts Evaluation of Urban Tunnel and ventilates, illuminates and the solution of fire-fighting life-saving.
To achieve these goals, the technical solution of the utility model is as follows: the Impacts Evaluation of Urban Tunnel version of a kind of lateral open, including road tunnel frame structure, it is characterized in that described road tunnel frame structure side arranges uncovered structure, described road tunnel frame structure arranges open type side wall by uncovered structure side, and described open type side wall offers intercommunicating pore so that described road tunnel frame structure and uncovered fabric connectivity, uncovered structural top is opened wide, and open-mouth arranges out ground railing.
According to preferred embodiment of the present utility model, the side wall of described road tunnel frame structure arranges post and lintel system, forms intercommunicating pore between adjacent beam column, and the open area between side wall beam column is not less than 20% with the ratio of the road tunnel area of plane.
According to preferred embodiment of the present utility model, go out pavement of road absolute altitude outside ground railing bottom reinforcement bars xoncrete structure height distance and, not less than 500mm, go out ground railing total height not less than 1100mm.
According to preferred embodiment of the present utility model, described open top inside configuration arranges escape stairs.
According to preferred embodiment of the present utility model, described open top structural top is provided with transverse support bar.
Impacts Evaluation of Urban Tunnel structure open type side wall can need to be designed as beam column construction according to stress, it is ensured that opening wide rate, general rate of opening wide is not less than 20%.Open spaces is by the feature being in communication with the outside, it is provided that natural ventilating function, and daytime, according to the design allotment of road tunnel interior lighting, effectively utilizes nature light resources；Escape stairs is set in open spaces, also serves as fire-fighting life-saving channel and use, advantageously in Impacts Evaluation of Urban Tunnel operation security；Go out ground railing and the most effectively protect ground staff and vehicle, simultaneously work as the dividing function of urban streets.The utility model has the advantages that Appropriate application natural resources, energy-saving and cost-reducing, reduce investment, conscientiously practice national energy strategy.

Detailed description of the invention
Below in conjunction with specific embodiment of the utility model and accompanying drawing, the utility model is described in further detail.
This Impacts Evaluation of Urban Tunnel version is by road tunnel frame structure 1, open type side wall 2, uncovered structure 3 and goes out ground railing 5 etc. and forms.Road tunnel frame structure is by arranging post and lintel system 7 in open type side wall side, it is ensured that opens wide rate, carries out the design of physical dimension through Structure Calculation, meet structure stress needs；Open area between side wall beam column is not less than 20%, preferably 20% ~ 40% with the ratio of the road tunnel area of plane, fully meets the needs of gravity-flow ventilation；Uncovered structure 3 horizontal clearance degree is typically no less than 1m, and the setting space of the internal escape stairs 6 of open spaces is arranged with reference to Fire prevention specification and local municipal government regulation, generally no greater than 250m.Uncovered structural top is provided with transverse support bar 4, goes out pavement of road absolute altitude outside ground railing bottom reinforcement bars xoncrete structure height distance and is not less than 500mm, it is to avoid ground rainwater flows into, and railing total height is not less than 1100mm, it is ensured that the safety of traffic above-ground.
This utility model is applied to the conceptual design of certain Impacts Evaluation of Urban Tunnel engineering in one embodiment, and the restriction condition of this engineering is:
1) engineering is positioned at urban central zone, and boundary lines of roads width is less, and outside resident, shopping centre are main, expropriation of land difficulty.
2) road tunnel length is longer, more than 1000m, entirely secretly buries form as used, must be provided with complete ventilating system according to code requirement, and outside supplies to arrange wind tower building without land resource.
3) according to traffic flow analysis, road tunnel mainly solves the demand of passing by.
For this engineering roadblock, the Impacts Evaluation of Urban Tunnel version of a kind of lateral open of the present utility model is designed, as follows:
Using lateral open in road tunnel appropriate location, open wide side side wall and use contignation, column size uses 800mmx800mm, longitudinal pitch 6m, and the percent opening of conversion side wall is 34%.Top longitudinal beam size 800mmx1600mm, longeron top flushes with box-structure end face, meets frame structure stress needs.
Open spaces transverse width 3.2m, matches with side wall percent opening, and inside arranges double race escape stairs, and stair setting space is 100m, it is simple under the operating modes such as fire, personnel escape in time.
The ground railing that goes out of both sides is both designed as continuous aluminum alloy column and handrail form, plays the segmentation non-chronic systemic of surface road people and the function of car lane.
This utility model overcomes the difficult problems such as conventional similar engineering ventilation blower electric energy consumption is big, wind tower building takes up an area, passway for escaping is additionally arranged, engineering is implemented smoothly, implements to provide a kind of safe and reliable, technical feasibility, energy-saving and cost-reducing, economic and environment-friendly Impacts Evaluation of Urban Tunnel version for similar road tunnel.
