TIE ROD CONNECTION COMPONENTS
Eye Tie Rods are special bars with upset threads on one end, with the other end of the bar pressed and drilled into a flat eye shape which can be used to connect to a hinge joint or connection plate for high modulus walls.
Turnbuckles and couplers are the most common connections to extend the full assembly length of the tie rod system. Typical adjustment length is 90mm, but greater lengths are available on request. The minimum engagement length for full joint strength is one outer diameter.
Hinge Turnbuckles are utilised to account for possible settlement, as the two connection points are hinged.
Hinge Joints are generally provided for tie rods with extreme overall lengths or possible settlements. The standard design includes two eye tie rods connected by hinge plates and pins.
The Waling Assembly transmits forces from the sheet piling to the anchorage whilst simultaneously aligning and stiffening the wall. ESC offers standard hot rolled channel sections presented, but can also provide full options such as splicing plates and bolt holes. Alternatives that ESC can accommodate to are cold formed channels, or double wide flange beams or as the
HIGH MODULUS CONNECTIONS
ESC can design and fabricate a wide variety of Tie Rod connections for both King Pipe & H Piles that are easy to handle and install. Parameters required in the design of the connection are: preferred connection type, King Pile sizing and Tie Rod Bar sizing and strength. Presented are some typical designs but ESC can offer a full suite of options depending on the application and project requirements.
CORROSION PROTECTION OPTIONS
Corrosion Protection of Tie Rod Systems can be achieved with the following methods or a combination of these methods. Other less common options include encapsulation, cathodic protection and Teflon coating all of which ESC can either provide or give advice on.
ESC is able to supply the following accessories in addition to those specified in the previous sections:
