Ground Screw is a kind of ground drilling screw with spiral characteristics, including drill bit / drill pipe / spiral blade and connecting pipe. The drill pipe is connected with the input joint of power source; It is convenient to drive the screw into the ground and directly use it as a screw The spiral ground screw can penetrate and compact the soil around the screw hole, improve the side friction resistance of the soil around the earth screws , and make the screw foundation have strong bearing capacity, uplift resistance and horizontal resistance, small deformation and good stability.

1. According to the hot-dip galvanizing specification of ISO 1461:1999, different materials are selected according to the environment and customer needs. The steel is made of materials produced by famous large steel enterprises, and recycled steel is not used. IX. implement strict quality control in order to achieve the highest quality index.

2. The ground screw supplier professionally designed products have passed the mechanical checking calculation of professionals, software simulation and stress test of third-party institutions, and the mechanical properties are guaranteed. According to the strict guidance of the experimental data, the static load test, compression test, tensile test and lateral pressure test are carried out to evaluate the compression resistance, stability and durability of the product.

3. Compatibility with structure: different spiral screws are adopted according to different needs of customers. There is no need to damage the surrounding environment, dig the land or pour cement. The spiral ground screw anchor is directly driven into the ground, greatly reducing the cost.

4. 100% environmental protection, recyclable, non corrosive, and zero cleaning cost. The migration is simple and fast, with the possibility of moving anywhere and anytime, reducing the impact on the environment and minimizing the migration cost.

5. With the applicability of all soils, suitable spiral screws can be found no matter what soil (from clay to rock). Best performance price ratio, 20-year quality assurance, beautiful and practical. The installation is simple, convenient and fast without on-site welding or processing. Each machine can install up to 200 spiral screws every day.

6. High precision positioning, vertical entry into the ground, and the positioning accuracy is 1.5cm.

The raw materials for the production of spiral ground screw are: Q235 welded pipe. Generally, the qualified ground screw can be produced through the process of cutting, deformation, welding, pickling and hot galvanizing. Among them, pickling and hot galvanizing are important anti-corrosion treatment processes, which directly affect the service life of the spiral ground screw. The processing level of spiral ground screw directly determines the service life of metal ground screw. For example, whether the selected welded pipe has sand holes, whether there is false welding, and the weld width affect the future service life of ground screw and the quality of subsequent processing. Acid pickling is an important anti-corrosion basic process, while the time of hot galvanizing and the film thickness of surface zinc coating all affect the quality of anti-corrosion treatment of ground screw.

Generally, the spiral ground screw can be used for 20-30 years. The environment and use method of the use process also affect the service life of the ground screw, such as the acid-base degree of the soil, whether the operation process is proper, and improper use will lead to the destruction of the surface of the metal ground screw, the destruction of the metal protective layer, the acceleration of the corrosion of the metal ground screw and the reduction of the service life.
