Components and Advantages of Slipform Construction Technique
The slipform method of construction involves pouring concrete in a continuous and steady manner (theconstructor.org, SLIPFORM CONSTRUCTION METHOD, 2015). This technique is mainly used for building tall and complex structures such as skyscrapers, towers, bridges, dams, etc. In this technique, concrete can be poured in a non-interrupted and balanced manner. Slipforming is basically of two types: vertical slipforming and horizontal slipforming. In the former type, vertical structures such as the ones mentioned above are built by pouring concrete around framework components, which have been set up before. A sub-type of this method includes conical slipform construction technique, which is mainly used to build round and conical structures, especially with changing cross sections. Some examples of these structures are industrial chimneys and bridge pillars (slipform-austria.com, CONICAL SLIPFORMING, 2013). In contrast, horizontal slipforming, as the name suggests is used to make horizontal constructions such as roadways.
Slipforming construction method uses the quick cooling and hardening property of concrete. Thus, the concrete used should not be too hard or too soft; it should contain the right proportion of its constituents. This is important from a workability point of view. The poured concrete that hardens also needs resist surrounding machine vibrations and support the constructed structure. Several components need to be properly established before actual slipforming construction begins.
The slipforming construction technique is better than the age-old method that involves joining separate pieces or units of material. Slipforming technique eliminates the possibility of waste generation and is also considered to be quite safe, efficient and economical for working (theconstructor.org, SLIPFORM CONSTRUCTION METHOD, 2015). The following points explain more in detail the various components used and advantages of the slipforming technique.
One of the primary components of slipforming is the yoke legs, which are mainly used to lift and sustain the weight of the entire slipform structure as a single unit. They are also used to connect parts of the structure such as working platforms, beams, scaffolds, etc. To facilitate placing concrete in a proper manner, walk-away bracket are used, which are connected with their respective yoke legs. These make it easy for concrete pouring along with fixing any reinforcement units. Strand rods and lifting jacks are also considered as prime components of slipforming. They are used to lift the whole slipform assembly. They are usually set up at equal intervals for good weight distribution. The lifting process is also supported by hydraulic pump components (nbmcw.com, SLIPFORM TECHNIQUES FOR ACCELERATED CONSTRUCTION, 2007).
Slipforming method can provide many advantages to businesses. Slipforming can help to increase the overall rate of construction and work productivity. This method drastically decreases the use of building cranes, and in some cases, the cranes may not be required at all. Accessories such as scaffoldings, support bars, platforms, etc., are required on a minimal basis while using this method. This can help create more working space for workers along with a safe environment. Use of less accessory equipment can also help businesses to save on their costs. Slipforming also offers a lot of flexibility to construction businesses while building structures (designingbuildings.co.uk, SLIP FORM CONCRETE, 2016).
Construction businesses can avail slip form construction services from businesses, which deal with such techniques. One of the most reputed slipform assembling companies in Korea is Bygging Uddemann. Visit their website for more details.
