Precast Utility Tunnel

The prefabricated utility tunnel has the characteristics of high concrete strength, stable and good quality, and long service life. Its joints adopt special structures and construction methods, and waterproof and water-stopping materials are also used at the same time. Therefore, it can not only effectively improve the seismic grade but also effectively prevent water leakage and seepage. Compared with the cast-in-place concrete construction on site, its construction is not affected by weather conditions and geographical environments, and it has the advantages of good construction simplicity, a short construction period, a small working area, less waste generated, and less impact on the surrounding environment.
