Changsha has built 48 kilometers of pipe corridors, four of which have been put into operation, and basically completed the national pilot task.
Yesterday, the inspection personnel of the pipe gallery inspected in the underground comprehensive pipe gallery of Laodong road.
"The underground comprehensive pipe gallery is equivalent to the 'dormitory' of the pipeline. We will make them 'check in' according to the type of pipeline, and divide them 'up and down', which can not only solve the problem of 'road zipper' and 'air spider web', but also realize the intelligent and intelligent management of the pipe gallery." Peng Wanjun, general manager of Changsha pipe gallery project company of China Construction Fifth Engineering Bureau, told reporters yesterday at the monitoring and command center of Changsha underground comprehensive pipe gallery in the new high-speed rail city. The reporter learned yesterday from the Municipal Commission of housing and urban rural development that at present, 48 kilometers of pipe corridors have been built in Changsha, among which 10 pipe corridors such as gaotangping road have been built into the corridors, and 4 pipe corridors such as Laodong road have been put into operation, basically completing the national pilot task. Changsha comprehensive management corridor pilot PPP project (the first batch) was selected by the Ministry of finance as a national PPP demonstration case.
Corridor wireless sensor network, vibration optical fiber sensor, BIM + GIS visual management Reporters yesterday saw in the control center of Changsha underground comprehensive pipe gallery that a monitoring command center with an area of more than 100 square meters has been built here. With a variety of "black technologies", the monitoring images in the pipe gallery can be viewed in real time on the large screen. This set of self-developed Changsha pipe gallery integrated management platform is the first "BIM + GIS" system architecture, that is, through the combination of map and three-dimensional image, the direction of underground comprehensive pipe gallery and the location of entrance and exit are accurately marked and displayed on GIS map, and at the same time, the three-dimensional model of pipe gallery is established by using three-dimensional BIM Technology.
"This platform is the brain of the whole underground utility tunnel." Peng Wanjun introduced that the platform integrated more than ten subsystems, such as environment, security, fire alarm, voice communication, etc., and realized data fusion among monitoring systems, providing functions such as linkage alarm, linkage prompt, and comprehensive monitoring. "Just like human brain, it can realize corresponding processing methods according to different body reactions."
Operation: Machine + manual inspection and interconnection of pipe gallery
As the first underground comprehensive pipe gallery put into operation in Changsha, there are three loops of 110kV high-voltage wires in the underground comprehensive pipe gallery of Laodong Road, and it serves the surrounding areas. How to ensure the normal operation of this 3km long pipe gallery?
The reporter saw yesterday in the pipe gallery that there is an intelligent inspection robot installed in the pipe gallery. Hu Wei, an engineer of Hunan Zhongjian management Gallery Operation Co., Ltd., told reporters that the robot can work 24 hours without interruption, "the infrared HD camera is its' eye ', it can rotate 360 degrees, the nose' can detect oxygen, carbon dioxide and other gases, and there are many kinds of sensors installed on the whole body. Through different inspection modes, all kinds of facilities and equipment in the gallery can be accessed Conduct all-round "carpet type" inspection. "
In addition to machine inspection, manual inspection is also necessary. Yesterday, the reporter saw the inspection personnel in the pipe gallery, who was holding a tablet computer in his left hand and a flashlight in his right hand, and carefully inspected the pipe gallery. "I have to patrol every warehouse of the pipe gallery every day. I need to walk more than 12 kilometers a day." Wang Guang said.
Hu Wei introduced that the handheld mobile terminal can realize efficient patrol inspection and emergency disposal, and achieve the effect of comprehensive management and interconnection of the pipe gallery.
Objective: to build 100 km underground comprehensive pipe gallery by 2020
In April 2015, Changsha was approved as one of the first pilot cities of the national underground comprehensive pipe gallery, with a total length of 60.41 km and a total investment of 5.553 billion yuan, including 22 pipe galleries and 4 control centers. According to the relevant person in charge of the management Gallery Office of the Municipal Commission of housing and urban rural development, 22 pipe galleries have been started, 48 kilometers of which have been completed, and 2 control centers have been put into use; 10 pipe galleries such as gaotangping road have been put into operation, and 4 pipe galleries such as labor road have been put into operation. In particular, the Changsha comprehensive pipe gallery exhibition hall, located in the new high-speed rail City, has received more than 420 batches of various groups, becoming a "window" for the public to understand the pipe gallery. "In order to accumulate practical experience in the pilot work, we are carrying out a number of research projects on comprehensive pipe gallery, striving to create a" Changsha sample "of pipe gallery construction." The person in charge said.
The reporter learned that the pilot project of Changsha underground comprehensive pipe gallery was implemented by the high-speed rail new city, Hunan Xiangjiang new area and Changsha high tech Zone, all of which were constructed in PPP mode, and the project return mechanism adopted "user payment + government feasibility gap subsidy". At present, three pilot area project companies have been established, PPP contracts have been signed, and all preliminary PPP work has been completed. At the same time, the regional operation and maintenance company has been formally established, the pipeline access agreement is being signed one after another, and the power pipeline charges have been realized for the labor Road and Jingui road in the new high-speed railway area.
According to the requirements of the special plan for Changsha underground comprehensive pipe gallery, by 2020, Changsha will have built an underground comprehensive pipe gallery of more than 100 kilometers. By 2030, it is planned to build an urban underground comprehensive pipe gallery system covering the whole city with a total length of 400 kilometers and a network of trunk and branch pipes.
