Description

Extensible utility tunnel

Technical Field

The utility model belongs to utility tunnel construction field especially relates to an extensible utility tunnel.

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 utility tunnel construction avoids the influence and interference on traffic and resident trip caused by frequently digging the road 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. The pipeline arrangement in the utility tunnel is compact and reasonable, the space under the road is effectively utilized, and the urban land is saved. The number of the posts of the road and the inspection wells, rooms and the like of various pipelines is reduced, and the urban landscape is beautiful. The overhead pipelines enter the ground together, so that the contradiction between the overhead pipelines and greening is reduced.

The construction of the domestic comprehensive pipe gallery starts late. Before the reform is opened, pipeline corridors are generally arranged only in underground spaces of large public buildings or large industrial enterprises according to needs, or only comprehensive cable ditches mainly for weak current are simply placed. The first municipal comprehensive pipe gallery appears in 1994, and according to the planning requirement of constructing a Pudong new area in high-level development, after necessary technical data collection in the early stage and relevant subject research, a poplar road is developed in the Pudong new area in Shanghai to construct the first large-scale comprehensive pipe gallery in China. The overall length of the comprehensive pipe gallery is about 11km, and the comprehensive pipe gallery is buried under sidewalks on two sides of a road. The utility tunnel body is of a reinforced concrete structure, the cross section of the utility tunnel body is rectangular, and the utility tunnel body consists of a gas chamber (a single chamber is internally provided with a gas pipeline) and a utility chamber (internally provided with various communication, electric power and water supply pipes). According to the requirement of the operation management of the comprehensive pipe gallery, the auxiliary facility system of the Zhang Yangyuan comprehensive pipe gallery comprises a fire fighting, ventilation, drainage, power supply and illumination, monitoring management, information collection and processing system and the like in the comprehensive pipe gallery.

In order to meet the development requirements of urban construction in China, the underground space resources of cities are fully utilized, and various types of underground municipal pipe network facilities of the cities are gradually changed into centralized and unified urban underground pipeline comprehensive corridors. The urban underground pipeline comprehensive corridor is also called a comprehensive pipe gallery, namely a tunnel space is built underground such as an urban road, a factory area and the like, two or more municipal public pipelines such as electric power, communication, fuel gas, heat supply, water supply and drainage and the like are laid in the same structure, and a special feed opening, a vent opening, an access opening and a detection system are arranged to ensure the normal operation of the urban underground pipeline comprehensive corridor.

At present, assembled utility tunnel china begins to rise, but there is the atress problem mostly in the current assembled utility tunnel, the difficult problem of construction connection, and the higher problem of cost, and the production of founding, there is the difficulty in transportation and construction, and along with utility tunnel's quick application, current utility tunnel probably can not satisfy the operation requirement in the future, utility tunnel's coverage has not satisfied the expansion in city, it will certainly cause very big waste to plan utility tunnel circuit again, consequently, develop an extensible utility tunnel structure and become the problem of treating the solution urgently.
