Advantages of spiral pile over concrete column
2023-08-15
Spiral pile foundation system is a kind of metal pipe pile or column pile with spiral blades, which uses piling equipment to screw into the ground to replace the concrete independent foundation and strip foundation, and the pile top is connected with the load. Compared with concrete foundation, it has obvious economic, social and environmental benefits:1. the installation process of spiral pile foundation system is simple and easy to learn. During the production of concrete foundation, it requires setting out, excavation of foundation pit, formwork erection, reinforcement binding, pouring, pre embedding anchor bars, curing, formwork removal and other processes, which is complex and time-consuming. The installation of spiral pile foundation only needs setting out and piling. The piling machinery is exquisitely designed and simple to operate. The construction personnel can learn and master easily. They can use the impact drill, that is, they can use the piling machinery, which greatly simplifies the foundation production process.2. the construction speed of spiral pile foundation system is fast. According to the actual measurement, under the general soil conditions, using manual machinery, two people can completely screw the screw pile into the ground, which only takes 15 minutes. Compared with the concrete foundation production, it greatly shortens the construction time and improves the construction efficiency.3. the screw pile foundation system has higher installation accuracy. The production of the spiral ground pile is completed in the factory. The processing technology is better than the concrete foundation constructed on site. The equipment is used for the installation of the spiral pile. The installation process can monitor the vertical and horizontal accuracy of the pile at all times, so as to ensure the installation accuracy of the spiral pile foundation system.4. the spiral pile foundation system requires low knowledge of construction personnel. Due to the simple process of the spiral pile in the foundation system, the construction personnel do not need experience and can take up their posts after simple training. The construction of concrete foundation is complex, requiring personnel with civil engineering and relevant construction experience to take up their posts. Compared with the spiral pile foundation system, it requires higher quality of construction personnel.5. the spiral pile foundation system has low requirements for the construction environment. The components of the spiral pile foundation system are completely processed in the factory. During the on-site construction, only the equipment needs to be screwed into the ground, which completely gets rid of the dependence on water resources. At the same time, the spiral pile foundation system does not require high construction temperature, and it can still be constructed under low temperature in winter. Compared with the concrete foundation construction, it has wider applicability.6. the spiral pile foundation system will not cause any damage to the natural environment. The spiral pile uses equipment to apply torque and pressure on the top of the pile, so that the spiral pile can insert into the soil and the spiral blade can cut the soil. The spiral trajectory of the later stage spiral blade is the same as that of the previous stage, which will not have a disturbance effect on the soil. The pile body is made of steel components, which can be recycled without damage and pollution to the environment. The traditional concrete foundation needs site leveling and foundation pit excavation, which leads to the destruction of soil and vegetation, and the base material of the concrete foundation is water, cement, sand and stone, so the production energy consumption is high, and the material can not be reused.
