Restorative Research of Stone Arch Bridge in River Kotsuki

竹桥桥建于1848年，在1994年8月6日的暴雨中被毁。我们调查了这座由大石头组成的桥，并参照130年前的老照片绘制了它的修复图。由于检查的结果，重建的竹桥在桥的末端比原来的桥的高度更高。在拱桥的中心，铺砌的石头被排除在外，以保持水平水平。那是90年前的事了。通过混凝土的使用，桥内铺砌的路面达到了更水平的水平，以便车辆行驶。在桥的中心，混凝土的高度很薄。1994年被毁的竹桥石拱桥和新桥石拱桥研究项目大纲。该研究报告于1997年进行了审查。这些石拱桥是由更多的石拱桥组成的。因此，被摧毁的石桥不是圆形的，而是因为小川河的强烈水流向上移动到石桥的表面而像鸡蛋一样改变了形状。我们对毁坏的石桥进行了调查，并写了几张图，以便将拱石桥与毁坏的石桥进行比较。1997年修复西桥石拱桥的研究报告摘要。这座石拱桥建于1846年。为了修复西桥石拱桥，我们调查了一年，找到了原来的坡度。根据我们的研究，西桥被重建为与竹桥一样的桥，在桥的末端比原桥的高度更高。在拱石桥的中心，为了保持水平水平，铺砌的石头被排除在外。一百年前重建石拱桥的技术人员的工程技术很好，但最近逐渐下降了。西大桥由四个连续的圆圈组成，是日本最著名的桥。有人猜测，修复后的石桥——原来的桥长315米——180肯（日文）。少

Abstracts of research project for restoration drawing of bridge of TakenohashiBridge of Takenohashi was built in 1848 and was destroyed by heavy rain in 1994 on August 6 th. We surveyed the bridge consisted of big stone and drawed its restoration drawing on reference to the old photograph one hundred thirty years ago. As a resul of the examination, bridge of Takenohashi was reconstructed higher on the end of the bridge than the original bridge in its height. On the center of the arched bridge the paved stones were excepted in oder to maintain the horizontal level. It was ninty years ago.By the use of concrete, the surface of the paved road in the bridge was reached more horizontol level in order to drive cars. Concrete was used thin in height toward the center of the bridge.The outline of research project for the arched stone bridge of Takenohashi and bridge of Shinkanbashi that were destroyed in 1994.The reseach report was examined in 1997. These arched stone bridges were consisted of … More arched stonre circle. As a result, the dertroyed stone bridge was not round, but was changed like an egg in shape because the violent current force of river-River of Kotsukigawa moved up to the surface of the arched stone bridge. We surveyed the destroyed stone bridges and wrote several drawings in order to compare the arched stone bridge with the destroyed stone bridge.Abstract of research report that we restorated the arched stone bridge-bridge of Nishidabashi in 1997.The arched stone bridge was built in 1846. We surveyed it for one year to restorate the arched stone bridge-bridge of Nishidabashi and found the original slope. As a result of our examination, bridge of Nishidabashi was reconstructed like bridge of Takenohashi higher on the end of the bridge than the oniginal bridge in height. In the center of the arched stone bridge, the paved stones were excepted in order to maintain the horizontal level. The engineering of technical men who reconstructed the arched stone bridge was very good one hundred years ago but recently droped gradually. Bridge of Nishidahashi is consisted of four successive circle which is the most famous in Japan. It was guessed that the restorated stone bridge-original bridge was 315 meters-one hundred eighty Ken (Japanese word in length). Less
