拱桥是我国桥梁建筑上优秀的传统形式,它符合就地取材的原则。去年,我曾参加了小跨径拱桥的施工,今将施工过程介绍如下: 工程概况本桥为一孔跨径7.0公尺半圆拱式桥,拱圈厚0.45公尺,台高4.0公尺,拱上侧墙高2.72公尺,总高为10.67公尺,基础深度2.25公尺(最下层为140~#混凝土),拱圈为170~#混凝土预制块,除拱圈为120~#水泥砂浆砌外,其余均为80~#水泥砂浆砌块石。桥台及拱圈预制块于 Arch bridge is our bridge construction excellent traditional form, it is consistent with the principle of local materials. Last year, I participated in the construction of the small-span arch bridge. Now the construction process is described as follows: Project Overview The bridge is a 7.0-meter span semi-circular arch bridge with an arch of 0.45 meters in height and a height of 4.0 meters. Arch on the side wall 2.72 meters high, a total height of 10.67 meters, the basic depth of 2.25 meters (the lowest 140 ~ # concrete), the arch ring for the 170 ~ # concrete precast block, except for the arch ring 120 ~ # cement mortar Masonry, the rest are 80 ~ # cement mortar block stone.
