Bridge deck crash wall refers to the protection facilities set on both sides of the bridge to prevent vehicles from rushing out of the bridge deck. The traditional bridge deck crash wall is mostly made of concrete, but the concrete pouring needs a mold, and the traditional wooden or steel mold has a short service life, is easy to be damaged, and the production cycle is long, and the cost is high. So, is it feasible to use plastic molds to make bridge deck crash walls?
First of all, plastic molds have the characteristics of light weight, high strength, wear resistance, corrosion resistance, etc., and are suitable for the production of components of various complex shapes. Compared with traditional wooden or steel molds, plastic molds are more durable and have a longer service life, which can meet the requirements of bridge deck crash walls.
Secondly, the plastic mold production cycle is short and the production cost is low. Traditional wooden or steel molds need to be made in multiple processes, while plastic molds can be made in one go through injection molding, which greatly shortens the production cycle. In addition, the production cost of plastic molds is relatively low, which can reduce the production cost of bridge deck crash walls.
Again, the plastic mold is easy to disassemble and install, which is convenient for construction. Traditional wooden or steel molds need to use a lot of manpower and mechanical equipment in the process of disassembly and installation, while plastic molds can be easily and quickly disassembled and installed due to their light weight and simple structure, reducing the difficulty and duration of construction.
Finally, plastic molds have good plasticity and appreciability. The plastic mold can be customized according to needs to adapt to the production of bridge deck crash walls of different shapes and sizes. At the same time, the plastic mold can be reused, which reduces the waste of resources and is in line with the concept of sustainable development.
To sum up, it is feasible to use plastic molds to make bridge deck crash walls. The plastic mold has the characteristics of light weight, high strength, wear resistance, corrosion resistance, short production cycle, low production cost, easy to disassemble and install, and has good plasticity and durability. Therefore, the use of plastic molds can improve the quality and efficiency of bridge deck crash walls, reduce production costs, and promote the sustainable development of bridge construction.
