Galvanized Steel Ground Anchor Helical Screw Piles For Mooring Systems

Galvanized Steel Ground Anchor Helical Screw Piles for Mooring Systems

Product description

The helical ground pile is a kind of ground bored pile with a helical feature. It is composed of three parts: a hot-forged pipe body, a helical blade, and a connecting flange plate. The helical blade and the flange plate are welded onto the pipe body, and then the whole is hot-dip galvanized. It is screwed into the ground by a special helical ground pile screwing device, replacing the original concrete foundation, and the top is connected to the load.

Application Fields of Products

Application in the improvement of groundwater conditions in roadbed and slope

Due to the defects in design, construction, maintenance, and the influence of geological rock and soil permeability properties, the groundwater of roadbed and embankment slope tends to rise year by year, thereby softening the strength of roadbed and slope soil, causing roadbed and slope instability, affecting highway use and driving safety. By installing the transverse drainage pipe designed by the spiral pile improvement in the foundation soil and the slope soil body of the road base, the drainage conditions of the foundation and the slope soil can be effectively improved, the soil water level and its adverse effects can be reduced, so as to effectively extend the service life of the highway and improve the driving safety.

Application of road and bridge maintenance and emergency repair

Due to their ability to be installed quickly and immediately loaded, screw piles are an effective solution for the maintenance and repair of time-critical roads, bridges and slopes. The installation speed of the screw pile is basically about 3 meters every 5 minutes, and a 15-meter screw pile generally only takes 30 to 40 minutes from lifting to completion, and it is not affected by the weather. The installation of screw piles does not require large mechanical equipment, and it is relatively easy to enter the site and the entry cost is low in the emergency repair or maintenance site with difficult conditions. The installation of screw pile has low requirements for equipment, and the traditional construction machinery with power hydraulic equipment can be used for installing equipment, and the smaller equipment can also install the screw pile of large bearing capacity. Only two to three people are needed for one unit, which greatly reduces labor costs. Screw piles and screw anchorage are able to carry the load immediately after installation, which is an incomparable advantage for concrete foundations and supporting structures that need to wait for cement hardening and later curing. After the installation of the dynamic penetration pile, it is often necessary to wait for the supervoid water to dissipate before the load is applied, while the static installation of the screw pile can be carried immediately, and the bearing capacity will further increase over time.
