The surface of the concrete prefabricated parts produced by the plastic cast-in-situ formwork is smooth, compact and has a long service time. It can be used for a long time without frequent replacement, which can save a lot of production costs. The cast-in-situ plastic formwork includes the cast-in-situ ditch formwork and the cast-in-situ anti-collision wall formwork. The formwork is made of plastic materials, Therefore, the concrete prefabricated parts produced are much longer than the concrete prefabricated parts made of steel plates. The formwork must be operated reasonably. The detailed description of cast-in-situ steel formwork will be described in many aspects such as the size, shape and use advantages of the formwork. The thickness of the steel plate used varies with the volume of the formwork. Generally, the steel plate with a thickness of about 5mm is used to make the formwork, and the size of the formwork is not fixed, The person in charge of road construction project can make the formwork meeting his own engineering standards according to his own real engineering needs, and then use the formwork to make the cast-in-situ anti-collision wall.
The brief introduction of cast-in-situ formwork will be introduced from the two aspects of formwork production materials and use location to further understand the formwork. The production material of formwork is steel plate. The choice of steel plate can be made of ordinary steel plate or high-quality steel plate. The advantage of steel formwork is that it can be customized, The personnel of the engineering procurement department can customize the template suitable for their own project according to their actual use situation, such as size, use quantity and specific transportation location. It can be provided to the sales personnel and production workers of the template manufacturing factory. It usually takes 5 days from the customized template to the transportation to the use area, and the use time is very little. The advantage of plastic cast-in-place formwork is that it is generally available in stock, with short production time and fast turnover. It is used for projects with short construction period and urgent construction period, and the price is certainly cheaper than cast-in-place steel formwork.
