The surface of the metal pipe after hot forging is welded with a pipe pile wrapped with spiral blades. The spiral ground mainly consists of three parts: the hot forged pipe body, spiral plates, and connecting flange plates. The spiral plates and flange plates are welded to the pipe body and then hot-dip galvanized as a whole. The specialized spiral ground pile tightening equipment is screwed into the ground to replace the original concrete foundation, with the top connected to the load.
Simply put, spiral pile foundation is actually a type of pile foundation structure that can replace precast piles, cast-in-place piles, and other cement piles to support buildings. For example, in some soft soil geological areas, some houses may experience wall cracking due to foundation settlement. In this case, spiral piles can be used to improve the settlement situation.
Spiral ground piles are a new type of foundation building material that can partially replace traditional reinforced concrete pouring construction techniques, making building foundations 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. Construction advantages
Spiral ground piles are driven into the ground in a swirling manner, so the soil is not easy to loosen and can make good use of the soil's own conditions. From the blade structure of the spiral ground pile, it has good tensile strength and insertion grip.
2. Simple and efficient
As a new type of foundation technology, spiral ground piles have outstanding advantages such as easy construction, short cycle, minimal impact from construction environment, no damage to local environment, and easy migration and recovery.
3. Low cost
Compared to concrete formwork, steel reinforcement bundling, and pouring. The processes of pre embedding anchor bars, curing, demolding, and backfilling the foundation soil can save material and labor costs for spiral ground piles by simply positioning and driving them.
4. All weather construction
Construction can be carried out under most climatic conditions, such as rain, snow, freezing, etc., with minimal environmental impact.
In construction engineering, foundation is a crucial and important link, which not only reflects the quality of the project, but also relates to the stability and service life of the building. Therefore, the application of double leaf ground helical anchor in foundation engineering has become an indispensable part of the construction industry.
Double leaf ground helical anchor are undoubtedly an excellent foundation reinforcement material. double leaf ground helical anchor, as the name suggests, is composed of two rotating blades. This design not only increases the bearing capacity and shear performance of the ground pile, but also improves its stability and anti collapse ability. Its advantages also lie in its large bearing capacity, fast construction speed, low cost, convenient transportation, and better performance in dealing with various geological and climatic conditions.
In practical applications, double leaf ground helical anchor have been widely used in various foundation projects such as deep foundation pit support, subway tunnels, and bridge foundations. Especially in the case of limited urban land resources, the application of double leaf ground helical anchor can better solve spatial problems and provide strong support for urban construction. At the same time, double leaf ground helical anchors have also played an important role in earthquake disasters, reducing disaster losses and casualties.
The surface of the spiral ring is welded with several semi cones, and the direction of the tip of the semi cones is the downward extension direction of the central axis of the spiral ring. The semi cones pointing downwards can provide greater pressure during screwing in, making the screwing in smoother. When pulling out, the bottom surface of the semi cones plays a blocking role and has stronger resistance to pulling out.
As a new type of foundation technology, it has the characteristics of simple installation, convenience, short construction period, low dependence on water resources, minimal impact from environmental changes, no damage to natural soil environment, easy recovery, and migration. Its application scope is gradually expanding.
