The invention relates to a prefabricated body, a plain concrete arch bridge structure and a construction method thereof. The construction method comprises the following steps that a plurality of plain concrete blocks are prefabricated, the plain concrete blocks are sequentially arranged in an end-to-end mode, and a gap is formed between every two adjacent plain concrete blocks; wherein the plain concrete block body is provided with a first surface; connecting pieces are embedded in the ends, close to the first surface, of the plain concrete blocks, the connecting pieces are fixed, and the plain concrete blocks are connected; concrete is poured on the connecting piece, and a prefabricated body is obtained; the prefabricated body is hoisted to a preset position, and the prefabricated body is lifted to form an arch bridge structure. According to the prefabricated body, the plain concrete arch bridge structure and the construction method, the construction procedure is simple, the arch bridge structure can be formed only through one-time stretching of a crane, a large amount of manpower and material resources do not need to be consumed, the prefabricated body mode is adopted, the construction speed is high, interference to the surrounding environment is small, and plain concrete blocks can be repeatedly used after a bridge is disassembled.
本发明涉及一种预制体、素混凝土拱桥结构及其施工方法。该施工方法包括以下步骤：预制多个素混凝土块体，多个所述素混凝土块体依次首尾排列，且相邻的所述素混凝土块体之间具有间隙；所述素混凝土块体具有第一表面；在所述素混凝土块体的靠近所述第一表面的端部埋置连接件，并对所述连接件进行固定，将多个所述素混凝土块体连接起来；在所述连接件上浇筑混凝土，得到预制体；将所述预制体吊装至预定位置，提拉所述预制体形成拱桥结构。上述预制体、素混凝土拱桥结构及施工方法，施工工序简单，只需吊车一次拉伸即可形成拱桥结构，无需耗费大量人力、物力，采用预制体的方式，施工速度快，对周边环境干扰少，桥梁拆除后，素混凝土块体可重复使用。
