Basic concept of pipe piles:
Pipe piles are a long and narrow cylindrical concrete forming material, usually made of steel pipe or reinforced concrete pipe. Pipe piles are mainly used to reinforce and support buildings, bridges and other engineering structures.
Classification of pipe piles:
According to the different materials and manufacturing processes of pipe piles, pipe piles can be divided into the following categories:
1. Steel pipe piles: Made of seamless steel pipes or welded steel pipes (such as LSAW pipe), they have large bending and compressive strengths and are often used for foundation reinforcement of various bridges and buildings.
2. Reinforced concrete pipe piles: Made of steel bars and concrete, they have high bending and compressive strengths and are often used in the construction of various large-scale foundation projects, highway bridges and docks.
3. I-beam piles: Made of I-beams or channel steels, they can withstand vertical and horizontal loads and are often used to support soil, pile foundations, settlement compensation and reinforce existing buildings.
Use scenarios of pipe piles:
Due to their high strength, high stability and strong adaptability, pipe piles have been widely used. The following are the use scenarios of pipe piles in different engineering parts:
1. Construction engineering: used for the reinforcement and foundation construction of building foundations to prevent problems such as building tilt and cracks caused by foundation settlement.
2. Bridge engineering: used for the foundation reinforcement and support of various bridges, tunnels and subways to ensure the stability and safety of the project.
3. Wharf engineering: used for dock shoreline fixation, crane rail foundation, foundation reinforcement, etc., and can withstand strong waves and wind.
4. Water conservancy engineering: used for foundation construction and flood control of dams, embankments and hydropower stations, with strong flood resistance.
5. Environmental protection engineering: used for foundation reinforcement and pollution prevention of landfills and industrial waste treatment sites to prevent pollutants from penetrating into the soil and groundwater.
6. River embankment engineering: steel pipe piles or reinforced concrete piles are often used in the reinforcement of embankments of rivers and lakes.
7. Marine engineering: Pipe piles are essential infrastructure in construction sites such as docks, shipyards, and ports, and usually use steel pipe piles or prestressed concrete piles.
Advantages of pipe piles:
Using pipe piles as foundation piles has the following advantages:
1. Fast construction speed: The assembly and installation of pipe piles are very simple, and the construction period is short, which is very suitable for projects with tight construction period requirements;
2. Strong adaptability: Pipe piles can adapt to various geological environments, such as rocks, sand, clay, etc., and can meet different engineering needs;
3. Good seismic performance: Because pipe piles have their own strength, they cooperate with the friction and wall pressure of the underground soil layer, so they have good seismic effect;
4. Cost saving: Because pipe piles are easy to construct and have a short construction period, they can save manpower, cost and other resources, thus having a certain degree of economy.
Scope and conditions of application of pipe piles:
Seismic fortification intensity: Pipe piles are suitable for areas with seismic fortification intensity not exceeding 7 degrees. When used in areas with seismic fortification intensity of 8 degrees, they are only suitable for thin medium and lower liquefied soil sites and multi-story buildings with a structural height not exceeding 24m.
Geological conditions: Suitable for sites such as plain fill, miscellaneous fill, silty soil, silty soil, clay soil, slightly dense and medium dense sandy soil.
Design life: Suitable for pipe pile foundation projects with a design life of 50 years or less.
In summary, pipe piles are an important reinforcement material, which plays an important supporting and protective role in many projects such as buildings, bridges, docks, water conservancy, river embankments, oceans and environmental protection.
