Retaining Walls

Changing weather patterns are now a consideration for everyone, especially those who own residential properties in a hilly area. Because of topography, some residences have small areas that are flat and easy to use for gardens and recreational space. Others are constantly faced with erosion from adjacent steep slopes that channel floodwater and eroded soil and rock onto their property raising the fear of mudslides, injury, and damage to the main residence and outbuildings.

Gravity retaining walls are the answer to erosion and minimal useable space for many property owners. Gravity walls are engineered structures requiring less dependence on additional elements of non-gravity wall systems such as hand-placed boulders and armour stone to create a heavy mass. Precast concrete gravity walls require engineering that accounts for mass and stability that includes a design to counter lateral forces, drainage, and a locking system that holds segments in place.

Once a stable and durable gravity wall is in place, the increased surface area created by the wall can be used for gardens of all types, sheds, recreational activities, or secluded people places. Stormwater is controlled by the wall design offering greater protection from natural forces. It is highly probable that the increased useable space and unique aesthetics of a patterned precast concrete wall will add value to a property and increase a person’s assets.

Property owners may be concerned about maintenance of a retaining wall. If the wall is a patterned precast concrete system, the amount of maintenance is up to the owner who may adorn the surface with hydroponic gardens. Precast concrete gravity walls promise little or no maintenance. There may be periodic minor soil infiltration behind the structure as the earth settles.

Production Equipment and Accessories Procurement and Maintenance

Automatic Welding Cage Machines Parts and Accessories

Superior Wire & Technical Services is the exclusive distributor of Kyungnam (Kyung-nam) Machine Co. automatic welding cage machines in the USA. These machines create the welded wire cages used for producing reinforced concrete pipe in precast concrete pipe plants. The wire cages give tension to a concrete pipe, so it won’t crush under enormous pressures (weights).

Concrete gives the pipe tube enormous compressive strength. Working together, wire cages and concrete give precast concrete pipe structures a service life of well over 100 years. Automatic welding cage machines are vital elements to the success in profitability and quality of a concrete pipe production facility.

Automatic welding cage machines are used to fabricate reinforced concrete cages or mats. These cages are essential components in various concrete structures, such as pipe, columns, beams, piles, and other reinforced concrete elements requiring reinforcement.

Hydro vault form produces a 5-sided rectangular tub-shaped precast concrete box

Infra-Tech Steel Works specializes in providing steel forms for hydro vaults. Among the designs is a five-sided rectangular tub-shaped form featuring counter-weighted hinge-back doors, specifically engineered to facilitate single-operator use without the need for additional equipment.

Jackets are designed with versatility in mind, accommodating a range of removable extensions and various shapes. The inner core rectangular form has a mechanical collapsing feature, where four precision-machined vertical core walls smoothly move inwards and outwards through the use of a rotational cam crank.

Both the jacket and core walls can be customized with an array of wall shapes and profile recesses. Casting pallets are available in metal and non-metallic joint profiles.

To ensure a watertight seal, all casting pallets are equipped with an inside and outside chamfer-profiled ethylene-propylene diene monomer (EPDM) gasket. EPDM gasket material is renowned for its resilience against extreme temperatures and resistance to a variety of industrial chemicals, making it an ideal choice for outdoor applications.

Precast concrete boxes used for more than culverts

The concrete pipe industry has been supplying precast concrete boxes for storm drain culverts for more than 70 years where the application of boxes was specified rather than concrete pipe. During the 1980s, concrete pipe markets became more competitive and market share of small diameter concrete pipe all but disappeared. It was during that period that the concrete pipe industry and American Concrete Pipe Association (ACPA) began work on standards for precast boxes. The concrete pipe industry advocated a Standard for box culverts through ASTM’s C13 Committee (formed in 1931) to open new markets and applications that we now consider commonplace, including the ability to jack precast concrete boxes.

There are several ASTM Standards for producing precast boxes including the American Association of State Highway and Transportation Officials (AASHTO) Load-and-Resistance Factor Design (LRFD) Bridge Design Specifications. Precast concrete boxes produced and delivered by the Turner Company meet the Standards set by ASTM and AASHTO. The Turner Company is a member of the ACPA and benefits from the decades of work of ACPA and industry engineers in standardizing the production and application of precast boxes.

When people think of precast concrete boxes, they tend to associate them with culverts only. Many producers market their product as box culverts. There are however many uses of precast concrete box sections that extend their applications into markets far removed from storm water management and sanitary sewers. Concrete pipe producers supply precast box sections for pedestrian and animal underpasses, short-span bridges, underground detention systems; lift station wet wells; golf cart tunnels; marine wharfs and channel diversions, conveyor belt enclosures, and chambers or tunnels for underground utilities. In recent years, precast concrete boxes are being used for assembling tiny houses.
