Combined steel bridge deck rigid pavement structure and construction method thereof
The invention relates to the technical field of bridge engineering, in particular to a combined steel bridge deck rigid pavement structure and a construction method thereof. The rigid pavement structure of the combined steel bridge deck comprises a steel bridge deck, a grid protection layer, a cementing layer and an ECC material layer, the steel bridge deck is a tooth groove type steel bridge deck, the grid protection layer is laid on the steel bridge deck and made of corn straw pumice composite concrete, and the corn straw pumice composite concrete is covered with steel wire grids. A cementing layer is laid on the grid protection layer, the cementing layer is made of low-molecular 650 polyamide resin and used for bonding an upper layer and a lower layer, an ECC material layer is laid on the cementing layer, and the ECC material layer is made of a PVA fiber cement-based composite material. The problem that the rigidity of the bridge deck is greatly reduced due to cracking of the pavement layer is solved, and the service life of the bridge is prolonged.
本发明涉及桥梁工程技术领域，具体涉及一种组合钢桥面刚性铺装结构及其施工方法。该组合钢桥面刚性铺装结构包括钢桥面板、网格保护层、胶结层和ECC材料层，所述钢桥面板为齿槽型钢桥面板，所述钢桥面板上铺设有网格保护层，所述网格保护层采用玉米秸秆浮石复合混凝土，所述玉米秸秆浮石复合混凝土上覆盖钢丝网格，所述网格保护层上方铺设胶结层，所述胶结层为低分子650聚酰胺树脂，用于粘合上下层，所述胶结层上方铺设ECC材料层，所述ECC材料层为PVA纤维水泥基复合材料。本发明解决了铺装层开裂导致桥面刚度大幅下降的问题，延长了桥梁的使用寿命。
