Precast concrete box culvert

reinforced concretefor drainage systems

The precast reinforced concrete element named Box-Culvert which corresponds to closed buried boxes are usually used in the realization of technical galleries and hydraulic conducts, as well as in the construction of underpasses and agricultural passes for vehicles passages. Box-Culverts are self-supporting infra-structures of rectangular hollow section, which can be constructed by monolithic parts or by two overlapping parts. By being coupled to each other they allow the execution with fastness passes for animals, underpasses, hydraulic lines, drainage systems and service galleries (electricity, water, gas,telecommunication, etc). They are characterized for its performance and resistance ensuring a longer shelf life. The versatility of these structures becomes even more an option where strength, durability and economy are of dominant importance The use of it presents substantial advantages against other solutions, for example: •The adaptability to construction needs in section, landfill heights, overloads, etc; •Speed of execution and entry in service, therefore cost reduction; •Working and security conditions improvement due to speed and simplicity of the mounting procedures; •Greater durability due to quality control related to its production; •Product with CE marking in compliance with EN 14844:2006 + A2:2011; •etc. The connection between modules is done by type tongue and groove joint, with flexible or rigid joint according to filling and sealing materials to be employed.
