Highway sound barrier engineering must comply with relevant technical standards during the construction process, and also has a sound quality management system, and all the actual setting processes are carried out in accordance with relevant regulations. How to divide the sound barrier This item is also effectively divided according to the actual conditions of various projects.
Generally speaking, the road sound barrier can be divided into many different main control items, such as the main control item of the embedded part of the bolt, the main control item of the h-shaped steel column, and the main control item of the sound barrier board.
In fact, every project of the road sound barrier has different standards in the process of division. When they are divided into different projects, the error of the sound barrier must be effectively controlled, and during the construction process, To ensure absolute correction of the error, it is necessary to ensure that the sound barrier in each project is very strong, to ensure that the identity between the two boards is absolutely close, check the number of sound barriers, the same Also check the actual situation according to the actual method, and also have a comprehensive understanding and inspection of the general project.
During the installation of the road sound barrier, it must be ensured that they are all perpendicular to the suspension bridge surface and are uniformly placed in the collision prevention external wall. The horizontal transportation process is adopted, all of which are different. The method of rail transportation, the manufacturing methods used in the installation are all on the lifting holes, and they are slowly hoisted by pulleys. At the same time, in the process of manual installation, all the columns can be put down, and the four corners are put. The bolts are all mounted on the nut.
In the road noise barrier technical specifications, there are certain adjustments to the column, and such an adjustment itself has various experiments, which can be adjusted according to the relevant proportions. The stirring time is usually After about two minutes, after stirring and standing, almost one minute, they will generate bubbles. This bubble can disappear completely, and then cleaned after disappearing. During the cleaning process, gravity grout is basically considered. After the perfusion is completed, it should be covered with quilts for three days.
