Embodiment Construction

[0041] Examples see Figures 1 to 4 as well as Figure 6 As shown, a bridge-type prefabricated reinforced concrete concealed beam slab pavement system includes a foundation and a road slab, the foundation is a prefabricated inverted T-shaped strip foundation 2, and the road slab is a prefabricated reinforced concrete concealed beam slab 3. The upper surfaces of the prefabricated inverted T-shaped strip foundation 2 and the prefabricated reinforced concrete hidden beam slab 3 are pre-embedded with four wire pipes 5; the top surface of the wire pipes 5 is welded to the upper steel bar 3.1 The prefabricated reinforced concrete concealed beam slab 3 is mounted on the steps on the side of the prefabricated inverted T-shaped strip foundation 2, and an L-shaped rubber pad 4 is placed on the contact surface between the two.

[0042] see Figure 8 and Figure 9 , the wire pipe 5 is composed of an internally threaded casing 5.1, an externally threaded steel rod 5.2, a rectangular anc...

Abstract

The invention relates to a bridge type precast reinforced concrete hidden beam slab pavement system which comprises a foundation and a pavement slab, wherein the foundation a precast inverted T-shaped strip foundation; the pavement slab is a precast reinforced concrete hidden beam slab; four fiber tubes are respectively embedded in the upper surfaces of the precast inverted T-shaped strip foundation and the precast reinforced concrete hidden beam slab; the top surface of each fiber tube is in welded connection with an upper reinforcement of the precast reinforced concrete hidden beam slab; the precast reinforced concrete hidden beam slab is rested on a step on the side surface of the precast inverted T-shaped strip foundation; and an L-shaped rubber pad is laid between the contact surfaces of the precast inverted T-shaped strip foundation and the precast reinforced concrete hidden beam slab. The invention has the advantages of high structural strength, convenient transportation process, reusability, high construction efficiency and the like, and can be widely used for road rehabilitation and temporary construction road construction.

Description

technical field [0001] The invention relates to a prefabricated bridge-type pavement system and a construction method thereof. Background technique [0002] At present, the pavement structure system of road traffic is mainly cast-in-place concrete pavement system. Due to the slow setting and hardening of ordinary cement and the long development time of strength, it generally needs to be closed and maintained for 14 days until the concrete strength reaches more than 80% of the design strength before it can be opened to traffic. Delay the construction period. In addition, after the delivery process, it is usually encountered that the existing road surface needs to be repaired due to improper use or a long time of use. The repair process is complicated and the repair period is long, especially for important roads, which will have a great impact on public traffic. . In addition, in road construction and building construction, it is often necessary to lay some temporary constr...
