Problems solved by technology
[0002] The reinforced concrete viaducts currently designed and built in my country generally adopt cast-in-place structures, which require a large number of supports and formwork. The construction period is long, and the road under the bridge cannot be opened to traffic, which seriously affects traffic.

Embodiment Construction
[0018] The content of the invention has described the specific implementation manner of the present invention in detail, does not repeat here, needs to explain as follows: One, see Fig. 1 , precast concrete deck ( 1 ) and filled beams ( 2 ) of the prestressed hole ( 3 ) should be set at intervals, in stress holes ( 3 ) through prestressed steel bars, prestressed and anchored, can ensure the transverse stiffness and strength of the bridge deck. 2. See Figure 4 , every time two precast concrete bridge slabs are installed ( 1 ), both precast concrete bridge slabs ( 1 ) are connected to each other, while the two precast concrete decks ( 1 ) are fixed to the pier surface, which can ensure the strength, stiffness and stability of the bridge deck during hoisting and later use. 3. See Figure 6 、 7 、 8 、 9 、 10 、 11 、 12 、 13 , main piston ( 11 ) and travel piston ( 8 ) on the supporting gantry crane ( 5 ), some may fall on the preca...

A prefabricated assembly type viaduct bridge plate and an installation device thereof are mainly used for viaduct construction in the architectural engineering field. A plurality of prefabricated reinforced concrete bridge plates are assembled, a plurality of bridge plates are installed by a special portal crane, construction speed is fast, and underbridge road traffic is not influenced. The prefabricated assembly type viaduct bridge plate is mainly composed of prefabricated reinforced concrete bridge plates (1), filling beams (2), prestress holes (3), a portal crane (5) and retractable steel beams (6). The main construction method comprises stretching a sub beam (15) of one retractable steel beam (6) from a bridge pier A to a bridge pier B by a hydraulic system, temporarily fixing the sub beam (15) at the bridge pier B, pulling a main beam (14) of the retractable steel beam (6) from the bridge pier A to the bridge pier B by the hydraulic system, hoisting two prefabricated reinforced concrete bridge plates (1) by the portal crane (5), traversely moving the retractable steel beam (6), and continuing hoisting another two prefabricated reinforced concrete bridge plates (1) until all the bridge plates are laid.
Description
technical field [0001] The invention is mainly used for viaduct construction in the field of construction engineering. Background technique [0002] The reinforced concrete viaducts currently designed and built in my country generally adopt cast-in-place structures, which require a large number of supports and formwork, and the construction period is long. The road under the bridge cannot be opened to traffic, which seriously affects traffic. Contents of the invention [0003] The present invention solves the above-mentioned problems. It adopts a plurality of prefabricated reinforced concrete bridge slabs to assemble, and installs a plurality of bridge slabs with a special gantry crane. The construction speed is fast and does not affect the traffic on the road under the bridge; ( 1 ), filling beam ( 2 ), prestressed hole ( 3 ), gantry crane ( 5 ), telescopic steel beam ( 6 ); gantry crane ( 5 ) consists of traveling piston ( 8 ), translational piston ( 9 ) , the mast main...
