The length of the patterned steel plate is 1-2 times of the width, so that the patterned steel plate is convenient to lift, transport, pave and dismantle.
The elevation of the pavement panel is the same as that of the pavement at two sides, so that the upper surface of the pavement panel is level with the pavement at two sides, the pavement at two sides is connected, the pavement panel is integrated, a temporary passage-protecting surface of the central separation belt is formed, traffic at two sides is converted during passage-protecting, and traffic is ensured not to interrupt passage.
The utility model has the following beneficial effects:
1. the central dividing strip of the expressway is of a fixed width according to design specifications, and the characteristic is fully utilized by the utility model. The pavement panel of the temporary passageway-protecting surface structure paved on the conventional site is set to be the pattern steel plate which can be prefabricated in a factory, so that the mass production is facilitated. The temporary road surface protection structure has the advantages of convenience in field pavement and dismantling, less equipment required by field construction, short construction time and repeated use for many times.
2. The road surface structure is formed by paving the graded broken stone base layer on the central dividing belt of the expressway and assembling the processed road surface panels, so that traffic on two sides of the central dividing belt can be converted during the expansion construction of the expressway, and traffic is ensured not to be interrupted.
3. The pavement panel of the main body part of the pavement structure adopts the patterned steel plate to strengthen the anti-skid performance of the pavement, and the lower surface of the patterned steel plate is reinforced by adopting the channel steel with longitudinal grooves welded in a staggered way so as to improve the anti-deformation capability.
