According to the construction method of the building (structure) below the road, the fender posts and the crown beams are simply constructed, the construction time is short, temporary road sealing and shielding measures can be taken on the periphery of the road in a low traffic flow period, such as a late night period, and then construction is carried out to avoid road blockage; meanwhile, the fender post and the crown beam can be built gradually as required, for example, the road is firstly sheltered and a plurality of fender posts are built in the first low traffic flow period (such as the night of the first day), the shelter is removed to recover the traffic before the low traffic flow period is ended, then the fender post is built in the second low traffic flow period (such as the night of the second day), so that the fender post is built in a sectionalized mode, and the crown beam is built in a one-time mode or a sectionalized mode according to the situation after all the fender posts are built, so that the influence on the traffic capacity of the road is reduced to the maximum extent. The construction of underground space can be carried out under the condition that the road surface is not influenced to pass, no matter the passing of people or the conveying of materials can be carried out through the access opening, the road surface part of the access opening needs to be continuously shielded, but the passing of the lane cannot be influenced on one hand, and on the other hand, the construction only needs a small area and cannot cause too much influence on the passing of pedestrians. By the construction method, the road traffic capacity can be effectively guaranteed, the road is prevented from being blocked for a long time, meanwhile, the fender post can be used as a fender structure of an underground building (structure), and the construction difficulty and the construction cost of subsequent engineering can be effectively reduced.
