Low altitude road lighting solution in the u-shaped slot interchange project application

Hangzhou yuhang century avenue and 09 provincial road intersection in downtown near flat nanyuan at the southwest corner of the street and Joe town at the junction, the status quo for the jump flat crossing.

the reconstruction design scheme for the 09 provincial road line wear century avenue, and set up the cars on communication with the century avenue, 09 provincial highway transformation a length of 770 meters, wear under paragraph structure set up open u-shaped slot and dark buried section box culvert, the 09 provincial road main railway box culvert structure status quo, only on the west side of the existing of non-motor vehicles and new box culvert pipe culvert hole partial modification, motor vehicle road clearance 5 meters, the machine and the sidewalk clearance 2. 5 meters. After transforming 09 provincial road and century avenue for the urban main road, the design speed of 60 km/h, subordinate line 40 km/h, design life of 15 years for the asphalt pavement, bridge opening in 100, land area of about 14 acres, with a total investment of 1. 0. 6 billion yuan.

the project implementation, to improve the intersection traffic capacity, improve traffic conditions and reduce vehicle fuel consumption has positive significance.

lighting design scheme design one:

the original design according to the present situation of lighting project, the conventional street lighting. The specific arrangement for the u-shaped slot adopts double pick lights in the road, cars on the ground using a pick a hanging lamp, respectively, motor vehicle, non-motor vehicle driveways and pavements for lighting, road using high lamp. Tunnel segment ( Frame box culvert section) Using special tunnel light, double row layout, chamfering in frame structure.

has now completed the 09 provincial road paragraphs of renovation and century avenue ( 09 provincial road ~ stone line) Project adopts the conventional high lamp styles, such arrangement can maintain the consistency of the whole in the u-shaped slot, in the middle of the double pick light, relative to the ground is gradually reduced, and style has a certain influence on the whole landscape.

the typical layout of the lamps in the section below:

design 2:

tunnel segment ( Frame box culvert section) Design and plan of the same, for the u-shaped slot, according to the current treatment of similar projects in the large area of hangzhou, in the u-shaped groove side wall installation of lighting lamps and lanterns, generally USES the tunnel lights with the way ( Has adopted the embedded installation) 。 But this kind of installation way pavement illuminance deficiencies, especially the problems such as uneven illumination. The main reason lies in the conventional lamps and lanterns, Including the tunnel lights) Are in accordance with the mast installation design, only in certain circumstances to ensure the installation height of the range of lighting.

hangzhou photos related engineering is as follows:

NaFu road under wear interchange u-shaped slot lighting layout ( Tunnel light with the)

zhijiang road city balcony u-shaped slot lighting arrangement ( Tunnel light dark outfit)

zhijiang road city balcony tunnel lighting effect

( In the u-shaped slot tunnel lamp is lower part of the scope of the road lighting apparently insufficient)

u-shaped slot west lake tunnel lighting

( Whole road illumination is insufficient, only the light in a small scale flare)

the other parts of the tunnel u-shaped slot basic similar problems. Through a variety of market research, the designer of the u-shaped slot illumination has carried on the detailed design, the careful research, especially on the part of lamps and lanterns below design scheme is put forward.

in the u-shaped slot range, using the company's latest thorn ORUS low lever lamp lighting, lamps and lanterns installation height of the road is only 90 cm. This kind of lamps and lanterns USES revolutionary Flat Beam smoothing patent technology, has good flood lighting effect, to ensure the road illumination and uniformity. Because dark outfit only 90 cm high, below the normal driving vision height, which can effectively avoid glare, and later maintenance is very convenient, can effectively avoid the influence of the street lights maintenance for traffic.

at present, this kind of lamps and lanterns in China shenzhen, wuhan, changzhou, taiyuan has applications, mainly used for the interchange area lighting. As a result of street lamp height 90 cm, only basic can't see the light pole, also is advantageous to road landscape. Within the scope of u-shaped groove in the central isolation belt installed low lighting lighting lamps and lanterns, the ground still use a conventional cars on the street lamp light, decorate. Lighting arrangement is as follows:

low light pole installation position signal

this plan arrangement to avoid the way of the ups and downs of the light, bad visual effect, low light pole to install street lamp has good visual orientation; The ground tutoring high light pole can be consistent with the standard road and century avenue before and after.

intersection and within the framework of lighting:

this intersection area is larger, the proposal USES four decorate lighting light way intersection range, within the framework of using professional tunnel lamp lighting, lighting effect.

the final effect:

project was completed in 2010 at the end of November, because of the light pole shorter, the concealment of lamps and lanterns is very strong, a very small impact on the overall landscape during the day, the dealership staff such as do not pay attention to, basic sense the existence of street lamp. But in the evening, from sharp by the light of lamps and lanterns, the road is very clear, the induction and traffic safety provides great convenience.
