Prefabricated concrete pavement and construction method

Abstract

The invention provides a prefabricated concrete pavement and a construction method. A prefabricated pier foundation and a pier top positioning plate are adopted to provide support for a platform sliding rail and a pavement side mold, and a platform sliding beam can provide support for a scraper supporting beam and a vibrating supporting beam. Oblique prestress tie bars are adopted. When a cast-in-place surface layer is poured, pouring vibration and surface scraping can be synchronously carried out. An inserting type vibrating rod and a plane vibrator are adopted to cooperatively conduct concrete vibrating construction. A jig frame vertical die is connected with a jig frame bottom plate through a vertical die rotating hinge. A ductile transition layer is arranged between a prefabricated panel and a pavement base layer. Hoisting construction of the prefabricated panel is conducted through combination of rigid suspenders and special-shaped supporting plates. Penetrating positioning ribs are arranged in a prestressed rib penetrating pipe, and the prefabricated panel can be accurately positioned through a position control body transverse support and a position control body vertical support. An anchoring groove sealing body is made of a micro-expansion concrete material. The difficulty of cast-in-place surface layer pouring and prefabricated panel hoisting and positioning construction can be reduced, and the stress performance of the pavement structure is improved.

Description

technical field [0001] The invention relates to a prefabricated prefabricated concrete pavement and a construction method which can reduce the difficulty of cast-in-place surface layer pouring and prefabricated panel positioning and construction, and improve the mechanical performance of the pavement structure. Background technique [0002] Prefabricated concrete pavement is widely used in construction all over the country due to its advantages of short construction period, high reuse rate, convenient construction, maintenance and repair. However, because the prefabricated concrete pavement slabs are prefabricated components, the connection strength and overall mechanical performance of the components are often the key points and difficulties of engineering control. [0003] In the prior art, there is a prefabricated cement concrete pavement construction process, which rigidly supports the formwork, and pre-embeds dowel bars at one end and prefabricates dowel bar grooves at ...

Problems solved by technology

Although this construction method can solve the problem of connection between slabs, there are still room for further improvement in terms of overall structural performance improvement, accurate positioning of prefabricated slabs, and connection of prefabricated components and cast-in-place slabs.
