JETTY & WALKWAY FOUNDATION SCREWING

(Screw-Piles)

“ whether this broad spiral flange, or “Ground Screw,” as it may be termed, be applied … to support a superincumbent weight, or be employed … to resist an upward strain, its holding power entirely depends upon the area of its disc, the nature of the ground into which it is inserted, and the depth to which it is forced beneath the surface.”

ABC Diving Ltd offers a fast, economic and reliable way to built jetties, walkways and all other small maritime infrastructures foundations, even located at REMOTE LOCATIONS or inside SENSITIVE AREAS, by operating a small barge specifically built-in for such purpose and portable hydraulic tools for pilling, drilling, breaking.

The CHANCE®Helical Pier Foundation System

New construction foundations don’t have to be a headache. The CHANCE® Helical Pier Foundation System (photos above) gives you the performance of concrete without the drawbacks and liabilities of driven piles and drilled shafts.

The helical pier foundation can be devised to resist or support any load or application. And it’s fast. It can be installed with lightweight construction equipment and loaded immediately. There’s no concrete curing time, and predefined capacities are predictable, putting you in control.

Approved by national building code agencies BOCA, ICBO, SBCCI, CCMC and ICC, the CHANCE®helical pier and tension anchor has become the deep foundation system of choice for architects, builders, contractors, engineers and geotechnical firms.

The CHANCE®Helical Pier Foundation System is perfect for a wide range of commercial, industrial, institutional and residential applications — from new homes and high-rise structures to sound walls, communication towers and bridges. Here are just a few applications

The CHANCE®helical pier is a segmented deep foundation system with helical bearing plates welded to a central shaft. Load is transferred from the shaft to the soil through these bearing plates. As a result of their true helical shape, the helices do not auger into the soil but rather screw into it with minimal disturbance.

What the Helix Anchors/Piles foundation?

The bearing strata and the necessary or appropriate torque is achieved.

The helical pier foundation is preferred over driven piles, drilled shafts, grouted tendons, auger-cast piles, belled piers and other deep foundation systems for a number of compelling reasons:

"Outside of ...................... there was another bad case of the naysayer blues.

We were installing helical piers in place of very short 6″ by 6″ wood piers that were pushing out of the ground.
In a pre-job meeting, I showed the walkway owner that the walkway itself was structurally sound and that he only had to replace the wooden 6″ by 6″s. Others, however, thought that the helical piers would not work or that they would take too long to install.

Despite the opposition, we devised a process to do the work and received the order for the piers and brackets.
I went to the job on the first day of installation and the hydraulic drive head had been broken during shipping.

Day one was a washout, and the naysayers had a field day.
But Danbro shipped another drive head to the job immediately and we were back in business the next day.

In spite of the setback, the walkway owner" was able to install 85 piers over the course of four days!
The piers were installed on time, and have performed very well."

TO HARD SEDIMENTS FOR SCREWING? Not a problem!

We can either:

This sort of screwed or piled foundation will resist without any damage to cyclones, eartquakes, strong wind and rough sea.
