Background
The utility tunnel system not only solves the problem of urban traffic jam, but also greatly facilitates the maintenance and overhaul of municipal facilities such as electric power, communication, gas, water supply and drainage and the like. In addition, the system also has a certain shockproof and disaster reduction effect. For example, in 1995, during the great earthquake of Osaka, Japan, a large number of houses in the Shenhu city collapse and roads are damaged, but most of local underground comprehensive pipe galleries are intact, so that the difficulty of post-earthquake disaster relief and reconstruction work is greatly reduced. The utility tunnel plays an important role in meeting the basic demands of the civilian life and improving the comprehensive bearing capacity of the city. The construction of the common ditch avoids the influence and interference on traffic and resident trip caused by frequently digging roads for laying and maintaining underground pipelines, and keeps the road appearance complete and beautiful. The cost of repeated repair of the road surface and the maintenance cost of the engineering pipeline are reduced. The integrity of the pavement and the durability of various pipelines are maintained. Is convenient for laying, increasing, decreasing, maintaining and daily managing various pipelines. Because the pipeline arrangement is compact reasonable in the ditch, effectively utilized the space under the road, practiced thrift urban land. Because the number of the posts of the road and the inspection wells, rooms and the like of various pipelines are reduced, the urban landscape is beautiful. Because the overhead pipelines enter the ground together, the contradiction between the overhead pipelines and the greening is reduced.
Because be in the position below the ground, waterproof requirement to the construction is higher, and waterproof not can not locate in the later stage use and easily appear various potential safety hazards, the problem how to improve construction water-proof effects is urgently needed to be solved.
