Introduction of spiral ground screw
The surface of the hot-forged metal pipe is welded with a pipe pile wound with a spiral blade. The spiral mainly consists of a hot-forged pipe body, a spiral piece, and a connection flange. Galvanized. It is screwed into the ground by a special spiral ground pile tightening device, instead of the original concrete foundation, and the top is connected to the load.
Outstanding advantages of spiral ground piles
The spiral ground pile is a new type of foundation building material, and part of it can be used to replace the traditional reinforced concrete pouring construction technology, making the building foundation more flexible and fast. It saves construction costs such as ground leveling, waste soil treatment, and excavation, and can be widely used in foundation construction in various industries.
1.Structural advantage
Spiral ground piles are driven into the ground in a convoluted manner, so the soil is not easy to lose, and the conditions of the soil itself can be used well. From the perspective of the blade structure of the spiral ground pile, it has good resistance to drawing and inserting grip.
2. Simple and efficient
As a new type of foundation technology, spiral piles have outstanding advantages such as convenient construction, short cycle, little impact on the construction environment, no damage to the local environment, and easy migration and recycling.
3. Low cost
Compared with concrete support formwork, steel bar bundling and pouring. For embedded anchor reinforcement, maintenance, mold removal, and backfilling of the foundation soil, only the positioning and piling of the spiral pile is needed, and material and labor costs can be saved.
4. All-weather construction
Affected by the environment, it can be used in most climatic conditions, such as rain, snow, and freezing.
The spiral ground pile assembly method
1.Pile support
Center and height adjustment for precise installation and connection
2.Light steel chassis support
After using the vertical plate, it can be used for modular chassis, which can accurately and uniformly distribute the load
3. Hat-type support
Suitable for all types of structural engineering
4.U-shaped fixed support
The center and height of the wooden structure can be adjusted arbitrarily in the horizontal and vertical positions, which is easy to install
5.Flange support
Modular system for precise static load configuration
6.Screw fixing method
3 or 4 bolted design for easier and faster pole installation
Several spiral cones are fixed on the upper surface of the spiral coil. The tip of the spiral cone is directed downward from the central axis of the spiral coil. The downwardly pointing spiral cone provides greater pressure when screwing in. , The screwing in is smoother, the bottom surface of the half cone plays a blocking role when pulling out, and the resistance to pulling is stronger.
As a new type of foundation technology, it has the characteristics of simple installation, convenient installation, short construction period, low dependence on water resources, little influenced by environmental changes, no damage to the natural soil environment, easy recovery and migration, etc., and its application scope is gradually increasing. expand.
