Pipe gallery, that is, the corridor of pipeline. In chemical and related factories, many pipelines are gathered together and arranged outside the device or factory building, usually in the air, supported by supports, forming a corridor-like appearance. There are also some pipeline corridors located underground.

Generally, it is an "on" type.

The main places for centralized pipeline laying of large-scale devices are composed of columns, beams and trusses of steel structure or reinforced concrete structure, which can be divided into single-layer or multi-layer, passable or impassable.

Detailed description:

Pipe gallery, that is, the corridor of pipeline. Many pipelines of chemical plants and related factories are gathered together and arranged outside the factory or building, forming a corridor-like appearance.

Underground comprehensive pipe trench is a kind of public infrastructure formed by burying two or more pipelines underground. It is the development direction of urban lifeline engineering infrastructure.

What is the pipe gallery for?

Integrated electrical, water supply and drainage installation channels.

1. What is a common ditch and why should it be built?

Gonggou is a comprehensive corridor of underground urban pipelines. That is to say, building tunnel space under the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, and matching them with special inspection ports, hoisting ports and monitoring systems, and implementing unified planning, unified design, unified construction and management are important infrastructure and "lifeline" to ensure the operation of the city. Is a unified planning, design, construction and maintenance, in order to lay municipal public pipelines and built in the city underground municipal public facilities.

Function:

Underground common ditch plays an important role in meeting the basic needs of people's livelihood and improving the comprehensive carrying capacity of the city.

* * * The construction of the same ditch will avoid the influence and interference of frequent road excavation due to the laying and maintenance of underground pipelines on traffic and residents' travel, and keep the road capacity complete and beautiful.

The cost of pavement reconstruction and the maintenance cost of engineering pipelines are reduced. Maintain the integrity of the pavement and the durability of various pipelines.

It is convenient for laying, increasing, decreasing, maintaining and daily management of various pipelines.

Due to the compact and reasonable layout of pipelines in the same ditch, the space under the road is effectively utilized and the urban land is saved.

Due to the reduction of inspection wells and rooms for road poles and various pipelines, the urban landscape is beautiful.

Because the overhead lines are buried together, the contradiction between overhead lines and greening is reduced.

What project does the pipe gallery belong to? Who has the basic file information of the pipe gallery? Send it to me. Thank you.

Common ditch, also known as * * * common ditch, comprehensive ditch and * * * common pipeline, refers to the construction of a public tunnel space underground and the centralized laying of various public pipelines. Common trench can be roughly divided into four types according to the different properties and structures of the pipelines it contains: trunk common trench, branch common trench, cable common trench and trunk-branch mixed common trench. Common ditch, that is, the main line, is generally located below the center of motor vehicle lane or road, and mainly connects the original station (such as waterworks, power plants, gas factories, etc.). ) and branch common ditch. It usually does not directly serve the areas along the route. The pipes in the ditch mainly include electric power, communication, tap water, heat and other pipes, and sometimes drainage pipes as required. In the common ditch trunk line, power is mainly transmitted from EHV substation to primary and secondary substations, communication is mainly signal transmission between switches, and gas is mainly transmitted from gas plant to high voltage regulating station. The cross-section of trunk common ditch is usually round or multi-box, and it is generally required to set up working channels and lighting and ventilation equipment in the common ditch.

What is the construction method of pipe gallery project?

Q:

How to check and accept the urban underground common ditch project, and what regulations should be met?

The urban underground comprehensive pipe trench project can be accepted according to the corresponding partial projects first, which should comply with the current codes and regulations.

For example, Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering, Code for Construction of Industrial Metal Pipeline Engineering, Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering, and so on.

What does the construction of underground common ditch mean?

Underground common ditch is a public tunnel used for centralized laying of municipal pipelines such as electric power, communication, radio and television, water supply, drainage, heat and gas.

Promoting the construction of urban underground common ditch is an important measure to innovate urban infrastructure construction. Not only can we gradually eliminate the problems such as "road zipper" and "spider web in the air", make good use of underground space resources, improve the comprehensive carrying capacity of the city and meet the needs of people's livelihood, but we can also promote effective investment, increase the supply of public goods, improve the quality of new urbanization development and create new impetus for economic development.

What technology is used in the underground integrated pipe trench project?

According to the different design, open-cut tunnel, underground tunnel and shield technology can be used, all of which are possible.

Does the underground pipe gallery project belong to the municipal infrastructure construction?

Underground common ditch refers to a public tunnel for centralized laying of municipal pipelines such as electric power, communication, radio and television, water supply, drainage, heat and gas. Promoting the construction of urban underground common ditch, coordinating the planning, construction and management of various municipal pipelines, and solving the problems of repeated excavation of roads, dense overhead network and frequent pipeline accidents are conducive to ensuring urban safety, improving urban functions, beautifying urban landscape, promoting urban intensive and efficient transformation and development, improving urban comprehensive carrying capacity and urbanization development quality, increasing effective investment in public goods, stimulating social capital investment and creating new impetus for economic development. Therefore, the underground pipe gallery project belongs to the municipal infrastructure construction.

What's the difference between a comprehensive trench and a comprehensive trench?

1, common ditch (see above).

(1) Common trench is an underground structure and ancillary facilities to accommodate two or more types of urban engineering pipelines.

(2) The common ditch (called "* * * with the same ditch" in Japan and "* * * with the same pipe" in Taiwan Province Province) is a comprehensive corridor of underground urban pipelines, that is, tunnel space is built underground in the city, which integrates various engineering pipelines such as power, communication, gas, heating, water supply and drainage, and is equipped with special inspection ports, lifting ports and monitoring systems, and implements unified planning, unified design and unified management.

(3) In developed countries, * * * universal purchase has existed for more than a century, and its scale is increasing with the improvement of the system.

(4) According to the function of the receiving pipeline, the common ditch can be divided into trunk common ditch and branch common ditch.

(5) The underground common ditch system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and overhaul of municipal facilities such as electricity, communication, gas, water supply and drainage. In addition, the system also has a certain role in earthquake prevention and disaster reduction.

2. Comprehensive pipe trench (see the figure below).

(1) The comprehensive pipe trench will be equipped with special inspection ports, hoisting ports, drainage facilities, fire fighting facilities, ventilation facilities and detection and monitoring systems to facilitate the operation and management of the pipe trench.

(2) Compared with the traditional single burying method of municipal public pipelines, the urban comprehensive trench has obvious advantages:

(1) One-time comprehensive investment to avoid repeated ground excavation;

② Intensive utilization of underground space resources; Good disaster prevention performance;

(3) Unified management, convenient maintenance and reduced management cost;

(4) Reduce the number of inspection wells and chambers for roads and various engineering pipelines, and improve the urban environment and city appearance.

(3) However, it also has the following disadvantages:

(1) Urban comprehensive pipe trench is expensive, ranging from 20 million to 40 million yuan per kilometer.

(2) It is inconvenient to build the comprehensive pipe trench by stages.

③ One-time investment is expensive, and how to share the cost among all units is complicated.

3. The common trench is several times larger than the comprehensive trench in space, and the construction cost is several times or even dozens of times more expensive.
