Description
Technical Field
The application relates to an underground utility tunnel construction structure.
Background
The city comprehensive pipe gallery is also called as a comprehensive pipe gallery, integrates two or more than two municipal pipelines such as electric power, communication, gas, water supply, reclaimed water and the like, is generally built in the city underground and is used for laying the municipal utility pipelines, and comprises a trunk comprehensive pipe gallery, a branch comprehensive pipe gallery and a cable trench, wherein the trunk comprehensive pipe gallery, the branch comprehensive pipe gallery and the cable trench are intensively laid in the same building according to the planning requirements, so as to implement the municipal utility tunnel space for unified design, construction and management, and have the functions of drainage, illumination, communication, alarm and the like, the city comprehensive pipe gallery generally adopts an intensive design concept to effectively utilize the space under the road, save underground space resources, also stop the influence on the road passage and the surrounding environment caused by respectively excavating the various professional pipelines at irregular periods, thoroughly solve the problem of 'zipper paths' and generate obvious social and environmental benefits, reduce urban pollution, provide some energy for city operation to guarantee city operation's high efficiency, utility tunnel's common warning object includes: harmful gas concentration, environment temperature, humidity, ventilation, fire control, entrance guard, intrusion detection, video monitoring, night patrol and the like in the comprehensive pipe rack.
The construction method of the prior comprehensive pipe gallery comprises the following steps:
1. open cut cast-in-place method: the construction method comprises the steps of carrying out underground foundation pit excavation on the ground surface by utilizing a supporting structure under the retaining condition, and constructing an internal structure in the foundation pit. The method has the characteristics of simplicity, convenience in construction and low construction cost, and is suitable for the pipe network construction of newly-built cities.
2. Open cut prefabrication and assembly method: the construction method is an advanced construction method, and large-scale prefabrication fields and large-tonnage transportation and hoisting equipment are required. The method has the characteristics of high construction speed, easy control of construction quality, high repeated utilization rate of the die and low total construction cost of the project under the condition of large construction quantity of the pipe gallery.
3. A shield method: the shield machine is used for propelling in the ground, surrounding rocks around are supported through a shield shell and pipe pieces, collapse in a tunnel is prevented, meanwhile, soil body excavation is carried out in front of an excavation face through a cutter disc, the soil body is transported out of a tunnel through an unearthing machine and pushed in at the rear part by a propelling oil cylinder in a pressurizing mode, and precast concrete pipe pieces are assembled to form a tunnel structure.
4. Pipe jacking method: when the pipe gallery passes through various barriers such as railways, roads, riverways or buildings, a subsurface excavation type construction method is adopted. During construction, the pipeline is pressed into a soil layer by a hydraulic jack on a support and a foundation pit rear seat through a force transmission jacking iron and a guide rail, and simultaneously soil on the front side of the pipeline is dug and transported away. It is suitable for soft soil or water-rich soft soil layer. The open cut earthwork is not needed, and the influence on the ground is small; the equipment is few, the process is simple, the construction period is short, the manufacturing cost is low, and the speed is high; the method is suitable for medium-sized pipeline construction, but the pipeline has poor turning capability and is difficult to rectify.
