Tabulation and beautification are done in order to separate the area into streets, sidewalks, green spaces and for surface collection. In each case, the points and executive codes must be specified in the map, and the contractor is obliged to perform tabulation and eyebrow construction after correcting and leveling the surface and reaching the desired codes.
What is the Municipal Water Water Working Materials?
Precast concrete is mainly used for tabulation, and in some cases, according to the work conditions, in-situ concrete is used for tabulation. Due to the low height of concrete tables, these tables are generally without reinforcement and if the working height of the table is more and the soil drift is significant, reinforced concrete tables should be used. To direct and collect the surface water of alleys and streets, you can use channels with V-shaped or U-shaped sections of prefabricated or in-situ concrete.
Method
After leveling and underlaying the area, the contractor must first separate the streets and sidewalks by nailing, and after evaluating and taking the longitudinal profile according to the project line and the code of the taken nails, tabulate the finished floor codes. Determine and excavate the tabulation site based on the requested codes. It should be noted that the exact path of running the table in a straight line and arcs should be marked with color. Tabulation should be performed on a dense, solid and uniform substrate. In places where excavation must be done due to the unevenness of the ground and unsuitable subsoil, after excavation, it must be done to the desired level with appropriate materials such as rubble and foundation mortar. If for some reasons and based on the executive plans, the height of the tabulation is not the same and prefabricated tables cannot be used, then the tabulation should be done with concrete on site, the prefabricated tables should be tied after alignment and execution. If the tabulation length is long, according to the executive plans, expansion joints should be implemented with a width of at least 10-15 mm, the distance of the expansion joints should be less than 6 meters. Expansion joints should be covered with suitable materials such as asphalt.
