types of substructure works

Strip footing is the independent footing of two columns connected by a beam. Hence, in this way, different building structures require different types of foundations that can be deep or shallow. Since each structure has different behaviors and vulnerabilities, the design must be carried out according to the design criteria. The substructure work consists of the following components: Foundations: Use of grouting methods for improving foundation soil. Coping. In order for a site to be developed a number of other groundwork activities may have to take place and other substructures may have to be constructed.On sloping sites retaining walls may have to be constructed to make a level development platform to enable the best usage of the site area to be achieved. Log in to TheConstructor to ask questions, answer peoples questions, write articles & connect with other people. Buildings and bridges are often the first structures to come to mind, because they are the most obvious engineering creations. weight (load) is evenly distributed to the ground. Cladding: panel systems, infill systems, composite panel systems, internal partition walls.Roofs:Pitched and flat roof systems, roof coverings.Floors: Ground floors, intermediate floors, floor finishes. JF Foundationhas the staff and the skills coupled with the vast experience of its Management to cater for any or all of the solutions. Walls; roofs; structural frames; claddings; finishes; services. In order to enhance the aesthetic factor, pier caps are designed with curves. Soil nailing is undertaken by drilling holes and inserting steel bars into the slope face (typically a cliff face), then grouting them in place. A plinth beam helps to transfer and distribute the load evenly from the walls to the foundation. It includes columns, beams, slab upwards including all finishes, door and window schedules, flooring, roofing, lintels, and parapets. Ground anchors are generally steel wires with metal wedges on their ends. All Rights Reserved. When bearings are not present, the superstructure and abutment are integrated together, and these types of bridges are referred to as integral bridges (integral abutment bridge). It is mainly used for masonry wall foundations. The different types of substructures are described below. Flexural design is typically used for pile caps, but in some cases, the Strut-and-Tie Model (STM), were pile head reactions or pier bottom forces are obtained through global analysis, is used. 2. straight or pyramidal. The foundation helps to transfer the dead loads, live loads, and other loads coming towards the underlying soil. Geosynthetics fit in to two main categories, geomembranes and geotextiles. Building a substructure transfers the load of the superstructure to the ground beneath. It also contributes to better locking of columns or Substructures can be classified into piers (columns), foundations (footings), and abutments. The metal wedge end is driven pneumatically into the slope face, until the desired depth is reached, and the wire is pulled taught then attached to a finishing plate to maintain tension. What are the different types of handrails used in bridges. It is economical for a maximum depth of 3 m.
