CIVIL WORKS

CONSTRUCTION

 


(On left) walkway with a combination of Square and Round Shafts helical piles,
with timber support brackets designed to attach to battered piles for lateral support.

ABC Diving and its subsidiaries provide civil services
to the MARINE CONSTRUCTION and MINING Industries
in a wide variety of projects in-land and in-shore throughout Vanuatu and New Caledonia:

SMALL MARITIME INFRASTRUCTURES:

ABC Diving Ltd operates:

  • A small barge with specific hydraulic Head Drivers to:
    • Drive Helix-Anchors
    • Drill into the sea bed for pipe vertical positioning (in diameters up to 4") associated to water jetting for full foot embedment
    • Core Drill
  • A portable hydraulic Hammer for Pipes Piling (round and square)
  • Many other hydraulic tools for civil works (drilling, breaking, grinding, brushing, etc.).

we can:

  • BUILD small JETTIES, WALKWAYS, WHARVES, SEAWALLS in remote locations and sensitive areas
  • CREATE functional and distinctive designs for (small) piled jetties and walkways;
  • IMPROVE efficiencies and upgrade facilities to better meet needs and expectations;
  • REPAIR or REINFORCE all existing infrastructures (structural damages. foundation underpinning)
Power Unit (GT23) 8 and 12 GPM / Breaker (BR87), Sinker Drill (SK58)
These hydraulic tools are usable UNDERWATER at any depths.
(operated from a small barge)
Hydraulic Driver for Helical Anchors/Piers and Core Drill.

Weight: 102 kg

Actual Torque: 6,750 ft/lb

The different processes consist in:

  • STEEL thick PIPES or hollow sections deeply PILED into the sea bed through the sediments, rocksand or limestone by means of manual hydraulic Driver.
  • WOOD Piling into the sea bed through the sediments, by means of a small crane and WATER JETTING
  • HELICAL ANCHORS + Extensions DRIVEN into the sea bed through the sediments, by means of a hydraulic Head Driver operated from a small barge.

The advantages:

  • FAST and STRONG construction*;
  • NO CONCRETING;
  • Imperceptible infrastructure impact on the ENVIRONMENT;
  • NO VIBRATIONS;
  • Suitable to all almost all sort of locations and configurations;
  • Reasonable COST (in regard of a heavy machinery implementation);
  • NO POLLUTION due to excavation or concrete works;
  • NO sand motion DISRUPTION on surrounding beaches;
  • Easy removal, replacement or maintenance (for jetties and walkways).

* Throughout Oceania, subject to strong cyclones, small jetties and walkways can resist better to the stronger winds and rough sea if made of round steel sections profiles (galvanized according to AUS/NZ Standards) deeply anchored into the soil or the sea bed.

POST - PIPE - HOLLOW SECTIONS DRIVING into sea bed and soils


Portable Hydraulic Hammer & Puller.
  • We operate versatile Hydraulic Hammer that will drive sections of almost any configuration, including “U” channel,
    round or square.
  • Pipes or Hollow sections piling is ideal for small jetty construction from a beach, without any impact on the environment by avoiding any large equipment implementation. These tools can operate from the shore or from our small barge (draft 0,40 m).
  • The driving/piling capacities are the following:
    • #2, #3 and #4 lb./ft. “U” Channel Sign Post;
    • #3 and #4 /Strong Back “U” Channel Sign Post;
    • #1 Delineator Post;
    • 1 3/4" T-Post;
    • 1 3/4", 2-1/2 in./63.5 mm and 2 1/4" Square Post;
    • 2-5/8 in./67 mm Round Post;
    • 2" Round pipe and 2" Square.
  • For bigger Pile Pipe diameters, we proceed by pre-drilling and positioning/embedment by water-jetting.

LARGE MARITIME INFRASTRUCTURES:

We can be a useful Sub-Contractor for any large marine construction involving heavy machinery.

We can provide:
  • Scuba or Hookah diving assistance
  • Water JETTING (for cleaning or fast embeddment)
  • DREDGING and Underwater BREAKING or DRILLING
  • (Underwater) CUTTING and WELDING (Broco® Underwater system)
  • Pre-piling CORE DRILL (hydraulic core barrel and Pengo Driver Head)
  • Steel POST PILING to secure the work-site
  • Hydraulic engineer, Marine engines engineer, welder assistance.

In addition of previous: Hight Definition still PHOTOGRAGPHY and VIDEO survey reports.
