Characteristics of spiral pile:
1. According to ISO 1461:1999 hot dip galvanized specifications, different materials are selected according to the environment and customer needs. The steel is made from famous large steel enterprises, and recycled steel is not used. Implement strict quality control in order to achieve the highest quality indicators.
2. The mechanical properties of professionally designed products are guaranteed by mechanical checking calculation by professionals, software simulation and force testing by third-party organizations. According to strict guidelines, static load tests, compression tests, tensile tests and lateral pressure tests were carried out to evaluate the product's compressive resistance, stability and durability.
3. Compatibility with the structure: different screw piles are adopted according to the different needs of customers. No damage to the surrounding environment, no digging or cementing, screw piles are driven directly into the ground, greatly reducing costs.
100% environmental protection, recyclable, non-corruptible, zero cleaning cost. Migration is simple, fast and possible to move anytime and anywhere, reducing the impact on the environment, so that the migration costs are minimized.
5. With the applicability of all soil, no matter what kind of soil (from clay to rock), can be found suitable for the spiral pile. The best cost-effective 20-year quality assurance, beautiful and practical. Simple and convenient installation without on-site welding or processing, each machine can install up to 200 screw piles per day.
6. Highly accurate positioning vertical into the ground, positioning accuracy is 1.5cm.
Operation conditions
1, geological data, construction drawings, construction organization design has been complete.
2. Ground and underground obstacles within the scope of the construction site have been removed or dealt with. The site has been levelled, the soft site affecting the operation of the construction machinery has been properly treated and drainage measures have been taken.
3, construction water, electricity, roads and temporary facilities are ready.
4, the site has been set up measurement base line, level base point, and properly protected.
5, in the construction of complex soil layer, should be carried out in advance, the number of not less than 2.
The production process
Production of spiral pile raw materials: Q235 welded pipe. Spiral pile can be produced through cutting, deformation, welding, pickling, hot dip galvanizing and other processes, among which pickling and hot dip galvanizing are important anti-corrosion treatment processes, which directly affect the spiral
Service life of ground pile. The processing level of spiral ground pile directly determines the service life of metal ground pile, such as whether the welded pipe selected has sand hole, whether there is virtual welding, weld width will affect the future service life of ground pile and the quality of subsequent processing, pickling is an important prevention
The process of corrosion foundation, the time of hot dip galvanizing and the thickness of galvanized film on the surface all affect the quality of anti-corrosion treatment of ground pile. Generally, the screw pile can be used for 20-30 years. The service life of ground pile is also affected by the environment and using method
Life, such as the degree of soil acidity and alkali, whether the operation process is appropriate, improper use, will lead to the destruction of the surface of the metal pile, the metal protective layer is destroyed, resulting in accelerated corrosion of the metal pile, reduce the service life.
