The toll Island mold of expressway toll station is a steel mold processed according to the island head and tail used at the import and export of each expressway toll station. It has large volume, special shape and structure, and cast-in-situ mud construction. Of course, the toll Island mold has high processing requirements, convenient disassembly and fast construction. The mold is cast-in-situ. Generally, the construction requirements are high, and the mold needs to be used on site. The toll island of expressway construction needs to be constructed synchronously according to toll stations, toll monitoring stations, surrounding anti-collision walls and other measures. There is no sequence, but there are many requirements for construction personnel.The mold of expressway toll island is used in the way of multi block connection. Therefore, before mold processing, the production state of the mold must be determined. Many workers directly take out the mold to start processing. The preliminary inspection is very important. The deformation, aging and expansion of the mold affect the forming effect of expressway toll island. The mold of expressway toll island shall be connected after inspection, Temporarily fix it at the construction site, pour mud and wait for solidification and air drying, and then harden and decompose the mold with mud.
