Fabricated prestressed heat-resistant cement concrete pavement and construction process thereof

Abstract

The invention discloses a fabricated prestressed heat-resistant cement concrete pavement and a construction process thereof. The pavement is formed by splicing a plurality of fabricated prestressed heat-resistant pavement plates which are parallelly paved and connected into a whole through transverse prestressed steel stranded wires, wherein each fabricated prestressed heat-resistant pavement plate comprises a fabricated prestressed pavement plate which consists of a plurality of pavement plate blocks connected through connecting plates, and a vermiculite concrete heat-resistant paving layer which is paved on the fabricated prestressed pavement plate; each pavement plate block comprises a plurality of common plates which are connected into a whole through longitudinal prestressed steel stranded wires; and the connecting plates and the common plates are cement concrete prefabricated plate blocks. The construction process comprises the following steps of: 1, prefabricating the cement concrete prefabricated plate blocks; 2, transporting the cement concrete prefabricated plate blocks; and 3, paving the pavement. The pavement is reasonable in structural design, convenient to construct, low in input cost and short in construction period, and has heat resistance, construction quality is easy to ensure, and various practical problems of the traditional fabricated cement concrete pavement can be solved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated cement concrete pavement construction, and in particular relates to an assembled prestressed heat-resistant cement concrete pavement and a construction process thereof. Background technique [0002] Prefabricated cement concrete pavement has outstanding advantages such as mass production and fast construction progress, but the problem of effective load transfer between slabs in traditional prefabricated cement concrete pavement has not been solved, so there is a problem of poor integrity, which affects The further popularization and use of prefabricated cement concrete pavement. In addition, the traditional prefabricated cement concrete pavement has defects and deficiencies such as late opening to traffic and difficult repairs. At the same time, because ordinary cement concrete absorbs a lot of heat in summer, the traditional prefabricated cement concrete pavement absorbs a lot of heat, whi...

Problems solved by technology

[0002] Prefabricated cement concrete pavement has outstanding advantages such as mass production and fast construction progress, but the problem of effective load transfer between slabs in traditional prefabricated cement concrete pavement has not been solved, so there is a problem of poor integrity, which affects The further popularization and use of prefabricated cement concrete pavement

In addition, the traditional prefabricated cement concrete pavement has defects and deficiencies such as late opening to traffic and difficult repairs.

At the same time, because ordinary cement concrete absorbs a lot of heat in summer, the traditional prefabricated cement concrete pavement absorbs a lot of heat, which is an important reason for increasing the city's "heat island effect" in summer.
