Problems solved by technology

[0003] In the prior art, the bridge deck is generally made of reinforced concrete, and the construction method of precast concrete or pouring on site is adopted. However, due to the strong brittleness of the concrete itself, it is easy to crack after being impacted by the heavy load of the vehicle, and the surface will peel off quickly after cracking. , the surface is damaged, which brings safety hazards

Embodiment 2

[0040] This embodiment provides a construction method for the combined bridge deck structure described in Embodiment 1, which specifically includes the following steps:

[0041] First install the steel plate 1, carry out sandblasting and cleaning and drying the steel plate 1; then weld the wave surface of the equilateral angle steel on the upper surface of the steel plate 1; lay the grid layer 2 on the upper side of the equilateral angle steel, and Spray the first layer of rubber in the grid of 2, the dosage is 0.6-1.1kg / m 2 ; After spraying the first layer of rubber, use the rolling tool to roll the first layer of rubber evenly to make it equal to the grid of grid layer 2; then plant gravel on the first layer of rubber, The particle size of the crushed stone is 4.75-9.5mm; then spray the second layer of rubber on the crushed stone, the dosage is 0.35-0.45kg / m 2 ; Finally pour the ECC material on the second layer of glue. By sandblasting, derusting, cleaning and drying the s...

Abstract

The invention discloses a combined bridge deck structure and a construction method thereof. The combined bridge deck structure comprises a steel plate, an equal leg angle with the corrugated surface, a mesh layer, a first adhesive layer, a gravel layer, a second adhesive layer and an ECC material layer, wherein the equal leg angle is welded to the steel plate, the mesh layer is arranged on the upper side of the equal leg angle, the first adhesive layer is arranged inside meshes of the mesh layer, the gravel layer is arranged above the first adhesive layer, the second adhesive layer is arranged above the gravel layer, and the ECC material layer is located above the second adhesive layer. ECC is used for replacing existing concrete, the structural safety, durability and continuity can be improved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a composite bridge deck structure and a construction method thereof. Background technique [0002] The bridge deck, also known as the roadway deck, is a heavy structure that directly bears the wheel pressure of the vehicle. The bridge deck structure is the core part of the whole bridge. The quality of the bridge deck laying will directly affect the service life of the whole bridge. Therefore, the laying of the bridge deck is particularly important, and the requirements for material selection and construction process are quite high. [0003] In the prior art, bridge decks are generally made of reinforced concrete, using precast concrete or on-site pouring construction methods, but due to the strong brittleness of the concrete itself, it is prone to cracking after being impacted by heavy vehicles, and the surface will peel off quickly after cracking , the surface is dam...
