The municipal supporting pipe network is an important part of modern urban infrastructure, which is essential to ensure the normal operation of the city and the quality of life of residents. In 2024, the comprehensive unit price of civil works of sewage plants covers multiple construction links, and the following is an analysis and explanation of these **:
1.Backfill: 27 yuan m
This ** refers to the cost of backfilling, i.e. the cost of filling the soil after digging the trench. The quality and construction method of backfill have an important impact on the stability and durability of pipe network engineering.
2.Backfill sand: 245 yuan m
Backfill sand is often used in pipe foundations to improve drainage performance and load-bearing capacity. This ** may include the cost of sand procurement and laying.
3.Trenching: 6 yuan m
This ** refers to the cost of digging trenches, including the rental of excavation equipment and the wages of the operators. The excavation of the trench is the first step in the construction of the pipe network, and it is very important for the smooth progress of the subsequent project.
4.Silt dredging: 32 yuan
Excavating silt is usually more complex than ordinary earthwork excavation because the silt is highly fluid and requires special handling and transportation methods.
5.Backfill rubble: 350 yuan
Rubble is a commonly used backfill material to reinforce foundations and provide good drainage properties. This may include the cost of purchasing and laying rubble.
6.Masonry stone wall: 523 yuan m
A rubble wall is a structurally sturdy wall that is used to support the soil and protect pipes. This ** includes the procurement, transportation and masonry wages of rough stones.
7.Rough stone wall joint: 15 yuan
Grout joints are the last step in the construction of rubble walls, which are used to fill the gaps in the wall and improve the waterproof performance of the wall.
8.C15 concrete cushion: 480 yuan m
C15 concrete cushion is used for pipe foundations, providing a uniform bearing surface. This ** may include the cost of materials and construction costs for concrete.
9.C25 concrete foundation: 565 yuan m
C25 concrete foundation has higher strength than C15 concrete and is suitable for foundation sections that bear greater loads.
10.Cast-in-place component reinforcement: 5820 yuan t
Steel bars are an important part of concrete structures and are used to enhance the tensile strength of the structure. This ** may include the cost of materials and construction costs of the rebar.
11-15.Reinforced concrete inspection wells and brick inspection wells: different specifications of inspection wells are different, including the materials, construction and installation costs of inspection wells. Inspection wells are an important part of the pipe network system and are used to inspect, repair, and clean pipelines.
16.C15 self-compacting concrete: 650 yuan m
Self-compacting concrete has good fluidity and filling, and is suitable for formwork with complex shapes or parts that are difficult to vibrate.
17.Diameter 500 reinforced concrete pipe: 184 yuan m
This ** refers to the cost of reinforced concrete pipes with a diameter of 500 mm, including the cost of materials and the cost of laying.
18.Demolition concrete pavement 25cm thick: 45 yuan
Demolishing concrete pavements is a labor-intensive process that requires specialized equipment and manpower.
19.Asphalt pavement 5+3cm: 116 yuan
Asphalt pavement is a commonly used pavement material for urban roads, and this ** includes the cost of asphalt mixture, paving and compaction.
20.Seal Oil: 2$5
Sealing oil is used in the surface treatment of asphalt pavement, which can improve the durability and waterproof performance of the pavement.
To sum up, the comprehensive unit price of civil works of sewage plants in 2024 reflects the costs in the construction of municipal supporting pipe networks. Contractors need to carefully evaluate the cost of each project during the bidding and construction process to ensure the smooth progress and economic benefits of the project. At the same time, the construction of municipal supporting pipe network also needs to take into account factors such as project quality, environmental protection and public safety to ensure the sustainable development of urban infrastructure. construction site
