When the cutting section of the expressway is excavated to the top surface of the upper roadbed, the side ditch construction is needed so as to discharge accumulated water on the roadbed in time. As the side ditch belongs to an important link in the construction process of a roadbed mainline, the side ditch has high requirements on line shape and appearance quality in the construction process. Especially, the installation of the prefabricated cover plate in the last procedure of the side ditch construction is very strict in elevation control, so that the method becomes a difficult point in the construction process.
The height of the original side ditch prefabricated cover plate is generally adjusted up and down by adopting hoisting machinery such as a small-sized loader, a truck crane and the like to be matched with manpower until the design requirement is met. However, one side ditch prefabricated cover plate is about 60kg heavy, and the construction site occupied by the hoisting machinery is large, so that the construction of other procedures in the site is easily interfered, and only about 40 side ditches can be installed by one installer per hour. In addition, the machine-to-machine cost of the hoisting machine is high, so that the construction cost is increased, at least five installers are needed for the installation of the hoisting machine, and the manpower is greatly consumed. Meanwhile, due to the error property of the control of the hoisting machine, the problems of collision, scratch and the like are easily caused to installation workers and the prefabricated cover plate of the side ditch, so that the loss is caused. In addition, the installation mode can cause large installation elevation and linear control errors of the single side ditch prefabricated cover plate, and the line shape and the appearance quality after installation are not attractive.
