.
When the pipeline crosses, pay attention to the minimum vertical clear distance: key points of the review of the comprehensive pipe network: ➣ consider the distance between the fuel gas and other pipelines, especially when crossing, review whether the position of the pressure regulating station affects the normal use Considering the backfilling of gas pipeline ➣ whether the location of thermal heat exchange station is appropriate and check the elevation of pipeline at the intersection with other pipelines ➣ determine whether the location of water supply pump house and main pipeline can meet the normal use of the whole park, check the elevation of water supply pipeline at the intersection of water supply pipeline direction ➣ drainage check the elevation of pipeline and municipal main pipeline to see whether water can be discharged
.
If the green space between two buildings is on the garage roof, it must be combined with the municipal rainwater well between the buildings, and the seepage and drainage pipeline shall be added at the apron near the building, especially the residence with courtyard on the first floor to lead the rainwater to the municipal rainwater well; 10
.
It needs the joint efforts of designers and constructors to achieve perfection
.
Whether important nodes such as landscape structures, sketches and important entrances and exits avoid gas pressure regulating box and outdoor box type substation; 2
.
In principle, all professional pipelines shall not pass through the courtyard on the first floor, so as not to affect future maintenance, especially control the access shaft of the main pipeline into the courtyard; 4
.
Pipelines with similar properties and similar buried depth shall be arranged together as far as possible
.
Whether the location of large group green space avoids the area with dense pipelines; 3
.
Wonderful review of previous periods 1
.
The pipeline with shallow buried pipe gives way to the pipeline with deep buried pipe 3
.
2
.
Try to keep the water supply and drainage pipeline away from the waterscape, and there shall be no pipe well in the waterscape; 8
.
There shall be no structures and trees and shrubs planted vertically for tap water and fire pipelines, and ponds, balls and hedges can be planted
.
The buried depth of water supply and drainage pipelines must be strictly controlled
.
In the design stage of the garden project, it is necessary to closely combine the design scheme of the municipal comprehensive pipe network and the comprehensive pipe network diagram to conduct the combined drawing review, so as to ensure the normal realization of the landscape effect and the normal delivery of the municipal pipeline
.
The one with small construction quantity shall allow the one with large construction quantity
. 
However, if the elevation of the pipeline entering and leaving the house has been confirmed and the buildings have been reserved, adjusting the horizontal and vertical position of the pipeline may increase the cost
.
Flexible material pipe gives way to rigid material pipe
.
The septic tank shall be located away from the main entrances and exits, squares and high terrain as far as possible, so as to reduce the impact of air pollution on residents; 11
.
Because the drainage pipeline is a non pressure pipe, the elevation of each municipal rainwater well must be understood before the design of the landscape drainage system to prevent rainwater from pouring back; 9
.

Comprehensive pipe network is an art, which needs to give consideration to all disciplines and check the elevation of each intersection
.
Pressure pipe gives way to gravity gravity flow pipeline; 2
.
Another major change in registration certificate! Cancel the requirements of major and working years, and the rolling cycle of achievements will change from 2 years to 4 years! 3
.
Power cable and telecommunication cable should be kept away from each other according to the principle that the power pipeline is on the east or south side of the road Telecommunication pipelines shall be arranged on the West or north side of the road in principle
.
The “four concessions” principle of pipe network construction: 1

.
Bendable pipeline gives way to non bendable pipeline; 3
.
The pressure pipeline gives way to the non pressure pipeline
.
4
.
The location of the fire pump adapter shall not be designed in a high terrain as far as possible, and the well chamber of the water pump adapter shall not be lifted and lowered according to the terrain at will; 6
.
Examples of underground pipeline crossing layout: water supply pipeline shall be above drainage pipeline, gas pipeline shall be above other pipelines (except thermal pipeline), power pipeline shall be below thermal pipeline The heat pipe above other pipelines shall be above the combustible gas pipeline and water supply pipeline
.
5, 6, Henan flood, the eight construction enterprises donated 77 million! CSCEC / China Railway / China Railway Construction Co., Ltd
.
In order to control the intersection of landscape structures, garden sketches and greening group planting with the location of municipal comprehensive pipe network, affect the later garden construction, and even lead to the failure of acceptance of individual municipal pipelines, thus affecting the timely delivery and normal use of the project
.

.
No structures, trees and shrubs shall be planted within 1.2m around the outdoor gas surge tank; 5
.
Check whether there are water supply and drainage pipelines at the lowest point in the general landscape plan, including the lowest point of green space, pool and water system, and whether the landscape design elevation can meet the buried depth requirements of water pipes
.
As the pipeline is a non pressure pipeline, it should be carefully checked Check the slope making direction of each pipeline ➣ pay attention to the spacing between power and other pipelines, and review the greening landscape of garden construction: the comprehensive pipe network is not only restricted by underground and aboveground buildings, but also restricted by garden construction and greening landscape
.
