Tunnel porous concrete permeable base construction method
The invention discloses a tunnel porous concrete permeable base construction method which comprises the following steps: S1, performing construction preparation, and determining the construction ratio and mixing time of porous concrete; and S2, discharging by using a mixing plant according to the construction ratio and the mixing time, and transporting the mixed porous concrete to a to-be-built construction position. And S3, paving by using a paver to form a permeable base layer, and immediately covering with a thin film after the paving construction is finished. And S4, after the permeable base layer is formed for 8 hours, water spraying maintenance is started, and the surface of the porous concrete is kept wet during maintenance. According to the construction method of the porous concrete permeable base layer of the tunnel, the optimal proportion meeting the pavement performance of the drainage base layer of the tunnel is completed through an indoor mix proportion test; and meanwhile, experience is provided for subsequent further construction popularization through tests of entity engineering and multiple in-field tests.
本发明公开了隧道多孔混凝土透水基层修筑方法，包括以下步骤:S1、进行施工准备，确定多孔混凝土的施工配比和拌合时间。S2、利用拌合楼按施工配比和拌合时间出料，并将拌好的多孔混凝土运输至待修筑施工位置。S3、利用摊铺机进行摊铺，形成透水基层，摊铺施工结束后，立即覆盖薄膜。S4、透水基层成型8h后开始洒水养护，养护期间保持多孔混凝土表面湿润。本发明的隧道多孔混凝土透水基层修筑方法通过室内配合比试验，完成了满足隧道排水基层路用性能的最佳配比；同时通过实体工程的试验和多次的场内试验，为后续进一步的施工推广提供了经验。
