They are typically used for conveying water. At other times they're accustomed provide a grade separated crossing for pedestrian and vehicular traffic . Various structures and material types are used. The most common types are box and pipes culverts. Precast concrete segmental box culverts are one among the foremost versatile and cost-effective pre-cast concrete products, meeting the requirements of fast paced construction projects. Flexibility in design and simple placement at site results in cost savings. There are many uses for pre-cast concrete segmental box sections as they can ease the construction work. These monolithic structures can be used for underpasses, service tunnels, subways, small bridges, storm water culverts, cattle underpass etc. These guidelines are only applicable for Precast Concrete Segmental Box Culverts. A Precast Concrete Box Culvert is an easy construction with segmental construction which is used to provide passage for roads, flowing water below roads, embankment or railways. Precast concrete segmental box culverts are popular in construction where time available for construction is less. With today's technology these precast box culvert can be constructed unto 40 - 60 m length of per day with precast sections available at site. To achieve this productivity at site these segments of finished section of required shape must be available in precast yard. Big size box culverts having transportation issue shall be transported as one unit are constructed from one ‘U’ sections and top slab casted separately; for on-site assembly. Sometimes two ‘U’ shapes s also are getting used . These are given rebated joints/V notched to permit sections to be laid open or sealed. Precast head walls and wing walls can also be provided for Precast Concrete Box culverts.
1. INTRODUCTION Structural design of precast concrete segmental box culvert shall be as per IRC:112 and IRC 122. Designs shall depend upon project requirements and applications. The precast concrete segments shall even be designed for handling and erection stresses supported the tactic of construction or site conditions. Box culverts can be designed to any standard or custom size and strength, including capability for withstanding any loads. Additional features can include toe walls, headwalls, wing walls, and watertight joints where required and shall be designed as per the provisions of IRC: SP:13. The precast concrete segmental box culvert shall be designed with IRC:122-2017 and IRC 112 with the specified forces. The dimensions of top slab, bottom slab and web shall be finalized based on designs and project requirements. 1.1 Advantages of Precast Concrete Segmental Box Culvert Following are the advantages of Precast box culverts: i. The entire construction period of a traditional culvert, such as base plate injection, formwork shutter / removal, side walls, ceilings and finishes, can take weeks, but shipping can reduce prefabricated parts to days. Install it. ii. Flexibility of range: can accommodate almost any size requirement: multicell sections of different shapes. iii. Ease and rapidity of installation: are often laid as single or in multiple cells. iv. The length of the culvert are often increased by adjoining the units with each other . v. By using Precsat box culvert segment we can eliminates need of transport and erection of shuttering and staging on site, to have a economic solution.
