It has good sealing performance, chemical corrosion resistance, low engineering cost, and is widely used in highways. A laying device is required during the silicone core pipe laying construction. However, the laying device needs to be driven by two machines when unwinding two rolled silicone core pipes at the same time, which increases the laying cost. In addition, the spacing between the two unwound silicone core pipes is fixed and cannot be adjusted according to actual needs, which brings inconvenience to use.
