Construction method of unbonded prestressed fabricated road with prefabricated double-ribbed beam and slab structure
The invention discloses a construction method of an unbonded prestressed fabricated road with a prefabricated double-rib beam-slab structure. The construction method comprises the following steps: step 1, surveying and setting out, and excavating a roadbed beam groove; 2, pouring a roadbed beam groove bottom cushion layer, and hoisting a roadbed beam; thirdly, the prefabricated double-rib beam integrated plate is hoisted; 4, perforating the unbonded prestressed tendons; 5, high-pressure grouting and hole sealing are conducted; sixthly, prestressed tendons are tensioned and anchored; seventhly, the first step to the sixth step are repeated till hoisting construction of all the structures is completed; step 8, comprehensively paving the asphalt surface layer; according to the principle of modular design, industrialized production, mechanical hoisting, a double-ribbed beam plate bearing system and combination of a prestress technology and a high-pressure grouting technology, the hoisting quality and efficiency are high, research, development and application of a new technology are enhanced, and favorable technical support is provided for high-quality development of the field of fabricated roads in China.
本发明公开了一种预制双肋梁板结构无粘结预应力装配道路施工方法，包括以下步骤：步骤一：测量放线，路基梁槽开挖；步骤二：浇筑路基梁槽底部垫层，吊装路基梁；步骤三：预制双肋梁一体化板吊装；步骤四：无粘结预应力筋穿孔；步骤五：高压注浆、封孔；步骤六：预应力筋张拉、锚固；步骤七:重复步骤一至步骤六，直至完成全部结构吊装施工；步骤八：沥青面层全面铺装；本发明遵循“模块化设计，工厂化生产，机械化吊装，双肋梁板承重体系，预应力技术结合高压注浆技术”为原则，吊装质量和效率均较高，加强新技术的研发与应用，为我国装配式道路领域高质量发展提供有利的技术支撑。
