Cangzhou City Construction Galvanized Spray Plastic Sign Column Traffic Sign Pole 180 Traffic Sign Pole National City Traffic

Description :

After arriving at the site, make full use of signs, road barriers and other facilities to manage pedestrians and traffic, and strictly follow the operating rules for construction. For pedestrians and operators, try to prevent accidents and ensure construction;

　　Strictly follow the requirements of the construction drawings and determine the location of the signs based on the direction of traffic flow;

　　After determining the position of the foundation, excavate the foundation at the designated location according to the dimensions specified in the design drawing. After processing according to regulations, erect formwork, tie steel bars, pour concrete, and ensure that the position of the anchor bolts and base flanges is correct and reaches the specified elevation;

　　The installation of the supporting structure for the 4 signs should be carried out after the strength of the foundation concrete meets the requirements and is approved by the supervising engineer. The flange of the pillar and the base flange of the concrete foundation should be level and tightly fitted, and the anchor bolts should be properly matched. After tightening the bolts, the pillar should not tilt;

　　Fix the signboard onto the pillar using sliding bolts, clamps, and other connecting accessories; The distance between the inner edge of the sign board of the column sign and the edge of the road shoulder should be 20cm, the height of the lower edge of the single column sign board from the road surface should be 250cm, and the clearance for cantilever installation should be 5.2m from the road surface;

　　After installing the signboard, the verticality and height of the signboard should be checked and adjusted to meet the specified requirements;

　　The sign layout for the installation of cantilever signs should be perpendicular to the centerline of the road. When installing roadside column signs, the sign layout should be as perpendicular or angled as possible to the centerline of the road: guidance and warning signs should be at an angle of 0-10 degrees, prohibition and indication signs should be at an angle of 0-45 degrees, and sight guidance signs should be at an angle of 80-90 degrees;

　　The installation of road traffic sign posts requires drivers to have sufficient reaction time to make necessary judgments for operation. Therefore, in order for the content of the logo to play such a role, there should be a certain amount of advance in the setting of the logo. In general, the larger the board size and simpler the content of road traffic signs, the smaller the advance distance of the sign can be.

　　The roadside traffic sign post must have a clear distance of 25cm from the outer edge of the shoulder, and there should be a clearance of 2m between the lower edge of the sign board and the outside road surface of the emergency stop zone. When setting up signs above highways, the clear distance between the lower edge of the sign board and the road surface should be greater than 5m.

　　The road traffic sign board is arranged at a right angle to the highway and can be slightly tilted inward. The front of the board faces the direction of traffic, making it easy for drivers to observe. There is no unified opinion on the issue of leaning roadside signs in road traffic signs. Some places believe that the signboard should only tilt inward when it is more than 9m away from the edge of the shoulder. When the signboard is less than 9m away from the edge of the shoulder, to prevent glare caused by reflection, it is tilted outward by about 30 degrees.

　　1. The setting (adjustment) of road traffic signs should be completed before the completion and opening of new (renovated, expanded) roads, and the signs related to these new (renovated, expanded) roads in the road network should also be adjusted synchronously to improve their settings. When road traffic conditions change, the setting of relevant signs should be adjusted in a timely manner. Highway number and city road name signs should be used as much as possible to enable road users to understand their route and location. 3. The logo should be regularly cleaned and maintained to maintain sufficient reflectivity and ensure visual recognition. During the use of the logo, it should also be avoided from being obscured by numbers or being affected by street lighting that affects visual recognition. The shape and color of the logo should comply with the provisions of this section during its service life. A speed limit sign, also known as a speed limit traffic sign, indicates that on a road where the speed limit sign or another speed limit sign with a different value is removed from the front, the speed of motor vehicles (in km/h for enterprises) is prohibited from exceeding the indicated value. The speed limit traffic sign is set at the starting point of the road where the speed of vehicles must be limited, and its speed limit value should not be less than 20km/h.
