[0002] At present, in the old city reconstruction, road construction and other projects, there are a large number of rainwater and sewage pipe network trenches that need to be built. Now prefabricated rainwater and sewage trenches, as a new type of drainage facilities, are gradually attracting people's attention. The current prefabricated rainwater and sewage trenches mainly include prefabricated side walls on both sides and prefabricated cover plates on the top. During the construction of the rainwater and sewage trenches, first cast-in-place concrete bottom plates are poured at the bottom of the excavated drainage trench, and then the prefabricated side walls are positioned and installed along the length of the drainage trench. After installation, support devices are required to prevent the prefabricated side walls from tilting. However, the current support device is to set supporting diagonal braces at the lower part of both sides of the prefabricated side walls. Such a structure is easy to hinder the activities of construction workers, and the support structure is unstable. Utility Model Content
