In the process of municipal road guardrail construction, there should be some correct methods, otherwise it will affect the overall operation progress and the specific construction situation.

Suggestions on the management measures for the setting of urban road traffic isolation barriers:

1、 There are many height specifications. It depends on the car and road conditions. The best one is the right one. Generally, the height of anti-collision guardrails is about 0.6-1 M. because of the serious problem of road occupation and parking, developers have installed isolation piles on urban roads that have not been handed over outside the community. Due to the non-standard installation, the isolation pile has not played a role, but has become an obstacle to traffic.

2、 Isolation piles on traffic roads are mainly set at the intersection of secondary trunk roads and trunk roads, which are effective facilities to control turning and left turning of motor vehicles. According to the national standard code for design of urban road traffic facilities, the spacing of separation columns should be 1.3m ~ 1.5m. The spacing of some isolation piles on the streets of Zhengzhou does not meet the standard, and some are only 0.5m, reflecting the randomness of the installation of local urban public facilities. At present, although some cities' economic volume, total population and other indicators have entered the ranks of big cities or megacities, the level of urban management is not high, resulting in a lot of municipal chaos: some are willful - or the sprinkler continues to spray water regardless of the slippery road surface, or the public facilities are installed indiscriminately; Others are simple and crude - or use "ladder law enforcement" to stop illegal installation of billboards, or pull up construction fences overnight to block roads; Others indulge and acquiesce - turning a blind eye to the frequent wedding photos taken at the zebra crossing and the frequent electric cars on the sidewalk.

3、 These chaos not only damage the image and taste of the city, but also bring trouble and danger to the masses. Although there are some objective reasons behind the chaos of urban management, such as the rapid expansion of urban area and unreasonable planning and construction, the main reason is that the concept and method of urban management lag behind. Compared with the cities with high international and domestic management level, the roads are not very wide and the facilities are very advanced, but they are clean and orderly. For the convenience of the people, according to the relevant provisions on separation facilities in part 6 of Chapter 7 protection facilities of the code for design of urban road traffic facilities, the height of separation facilities should be determined as required, and the spacing of separation columns should be 1.3~1.5 M.
