Construction method of large-span thin-wall concrete sound barrier
The invention relates to a construction method of a large-span thin-wall concrete sound barrier. The construction method comprises the following steps: step 1, performing foundation construction; step 2, performing vertical wall construction; specifically, pouring an arch frame of a sound barrier in a segmented mode, and pouring the vertical walls on the two sides firstly; step 3, performing main and secondary beam construction: mounting main and secondary beam steel bars, erecting a formwork, performing pouring to form main and secondary beams, and connecting and fixing the main beam and the vertical wall; connecting a prestressed inhaul cable to the lower chord position of the main beam, and tensioning the prestressed inhaul cable; step 4, installing prefabricated plates; specifically, installing the prefabricated plates on the outer sides of the main beam and the secondary beam to form a closed structure; and step 5, constructing a waterproof heat preservation layer; specifically, sequentially constructing a leveling layer, a waterproof layer, a heat preservation layer, alkali-resisting gridding cloth and an anti-crack mortar layer on the outer surface of each prefabricated plate. The construction method has the advantages that the sound insulation effect is good, large-span, ultra-long and ultra-high sound barrier structure construction is met, the foundation area is reduced, and the construction cost is reduced.
本申请涉及一种大跨度薄壁混凝土声屏障施工方法，包括以下步骤：步骤1：基础施工；步骤2：竖墙施工：将声屏障的拱架分段浇筑，先浇筑两侧的竖墙；步骤3：主、次梁施工：安装主、次梁钢筋，立模，浇筑形成主、次梁，并使主梁和竖墙连接固定；在主梁下弦位置连接预应力拉索，并进行张拉；步骤4：预制板安装，在主、次梁外侧安装预制板形成封闭结构；步骤5：防水保温层施工：在预制板的外表面依次施工找平层、防水层、保温层、耐碱网格布以及抗裂砂浆层。本申请具有隔声效果好、满足大跨度、超长、超高声屏障结构施工以及减小基础的面积，降低施工成本的优点。
