Responding to diverse construction needs in foundation work.

Ueda Kikou responds to various needs with solid achievements in removing underground obstacles and on-site construction pile methods.

All Casing Construction Methods

  • Revolving All Casing Construction Method

    Obstacles including hard ground and existing concrete, etc., are easily removed with the large bore and ability to reach great depths.

    • φ800 to φ3000

    The " All Casing Method " drills holes with a casing bit attached to the end of a revolving casing. Hard soil layers, tourmaline layer, cobblestone layers, bedrock, and reinforced concrete having a high N value can be drilled with a high efficiency.

    The balanced pressing force and highly accurate verticality facilitate large bore and deep construction.

  • BKF Construction Method(Vibration and noise measures)

    Environmentally-friendly drilling technology realizes " low noise and low vibration " in consideration of the neighboring environment.

    • φ1000 to φ2000

    This method uses the " BKF hydraulic hammer grab " with cylinder hydraulic transmission system. Drilling is advanced by driving the shell (drill point) into the ground with the weight of the hammer and force of the spring.

    A high-pressure hose is not required, and the resulting noise is lower.

    The crown is treated with special resin to reduce the noise. The hydraulic system ensures that the shell opening/closing force is strong, and that a high drilling performance is achieved.

  • Revolving All Casing Bottom Enlarging Construction Method / GSB Construction Method

    Suitable for enlarging the bottom of bedrock. This environmentally-friendly drilling technology incorporates " low-noise, low-vibration " measures in consideration of the neighboring environment.

    • φ1500 to φ2000(shaft diameter)
    • Enlarged bottom diameter ≤ up to shaft diameter + 1000 mm

    An enlarged bottom is drilled with an arm extending from the GBS bucket, using rotational torque of the revolving machine while applying a counterforce on the inner side of the casing.

    A construction range of shaft diameter + 200 mm to 1000 mm is supported.

  • NS ECO-PILE® / Screwed Steel Pile

    Screwed steel pipe realizing large vertical holding force and surplus soil free construction

    • φ700 to φ1600
    • 1.5, 1.75, 2.0-fold of blade diameter and shaft diameter
    • Drilling depth : Max. 70 m

    " NS-ECO PILE " is a steel pile with a helical blade welded to the edge. During construction, the steel pipe is rotated in with a casing rotator, etc. The wedge effect of the blade exerts a propulsion effect and enables smooth penetration.

  • Sky Chuck Method(Vibration, noise, hard bedrock measures)

    • φ1000 to φ2000

    " Low noise and low vibration " measures for neighboring environments. Perform crane work + earth drilling + hammer drilling with one unit!

  • MRT Construction Method

    Super Drilling Construction Method
    (Underground impediment removaland narrow ground measures)

    • φ800
    • φ1000
    • φ1200
    • φ1500

    This construction method is designed for removing underground impediments in narrow grounds, and can be used on a plot as small as 10 m x 15 m.

OPTION
F4C(F4 Catcher)

Maximum lifting capacity 40 tons. The catcher accurately lifts any type of obstacle.

  • For φ1500 to φ3000

Construction Methods for Low Spaces and Narrow Grounds

  • Revolving All Casing Method(Low Space Type)

    Easily remove obstacles such as hard ground and existing concrete with the large bore and ability to reach great depths.

    • φ800 to φ2000

    The low-space type revolving all casing method, capable of working under restricted spaces, is suitable for use near steel towers, under high-voltage power lines, construction sites under elevated bridges, and inside factories. The compact body is easy to handle, and is powerful in confined work spaces having height restrictions.

  • Micro Revolving Method

    Work in narrow spaces and places with low headroom

    • φ800 to φ1200
    • Ultra-light weighing just 9 tons
    • Drill even in places with just 4.5 m of headroom

    The micro revolving method is perfect for confined spaces and places with low headroom.

  • Low Headroom Sliding Method

    Work in narrow spaces and places with low headroom

    Work is possible even where headroom is restricted to 5.0m

    • φ1000 to φ1500

    Drastically improve work efficiency by working in low headroom spaces where heavy machines previously could not access.

Earth Drilling Method

  • Double Enlarged Bottom Earth Drilling Method / SY Method

    The mechanical bucket makes it possible to perform enlarged bottom piling with a 5-fold support force even in narrow places.

    • Shaft diameter : φ800 to φ3000
    • Enlarged bottom diameter : φ900 to φ4700
    • Drilling depth : Max. 81 m

    The SY method is a new onsite pile concrete enlarged bottom piling method that is capable of a large support force by drilling the enlarged bottom diameter to double or more the shaft diameter (enlarged bottom area max. 4.84-fold).

  • SB earthquake resistant pile e construction method

    Pile head steel pipe wound On-site construction concrete pile

    • Shaft diameter : φ800 to φ2500
    • Enlarged bottom diameter : φ900 to φ4700
    • Drilling depth : Max. 81 m

    The SB earthquake resistant pile e-construction method fully utilizes established on-site construction concrete piling methods. It is designed to increase earthquake resistance, increase the freedom of design, and reduce costs by attaching a commercially available steel pipe on the on-site construction concrete pile head or the entire shaft section.
