Example Embodiment

[0027] Example two

[0028] This embodiment provides a simple composite steel temporary bridge deck system construction method, which is to construct the simple composite steel temporary bridge deck system described in the first embodiment, including the following steps: Step S1: After excavation of the foundation pit, stones are thrown on Step S2: Arrange the longitudinal beams 12 between the piers 11, and then lay the bridge deck 13 so that the bridge deck 13 is fixed on the longitudinal beam 12; Step S3: Set baffles 14 along the length direction of the steel bridge on both sides of the width of the bridge deck 13; Step S4: Pave the graded gravel 15 on the bridge deck 13 to form a gravel layer, and The gravel layer extends from the center of the bridge deck 13 to both ends to form a bridge arch with a slope.

[0029] In the construction method of the simple composite steel temporary bridge deck system of this embodiment, in the step S1, after the excavation of the foundation pit...

Abstract

The invention relates to a simple composite temporary steel bridge deck system and construction method, and the system comprises a pier and a bridge arch located on the pier, the bridge arch includesa longitudinal beam located on the pier, the longitudinal beam is provided with a bridge deck, and the bridge deck is fixed on the longitudinal beam; baffles are arranged along the length direction ofthe steel toilet bridge on the two sides edges of the width of the bridge deck; the graded crushed stone on the bridge deck forms a crushed stone layer, and the crushed stone layer extends from the center of the bridge deck to two ends to form a bridge arch with gradient. The invention has the advantages of low cost, strong driving comfort and convenient dismantling.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a simple composite steel temporary bridge deck system and a construction method. Background technique [0002] For expressway construction, the primary task before the official construction is to run through the access road. During the construction of the access road, a temporary steel temporary bridge needs to be erected when crossing ravines and rivers. In the construction of steel temporary bridges, the bridge deck system generally adopts U-shaped standard bridge decks or other steel profiles. The bridge decks are spliced, and reinforced concrete pavement is poured on some bridge decks. The use of U-shaped standard bridge decks or other section steel splicing bridge decks has the following problems: First, the cost is high. This type of bridge deck includes checkered steel plates and various section steels welded on it. Second, when the bridge deck is installed, th...
