经过三年的努力,

位于四川与重庆的交界处,是吉明,和龙三省的主要拱门

为完成年度开放奠定基础。

吉明三桥是该省交叉和改变的道路和桥梁之一,

它的完成将改变

四川省叙永县,云南镇雄县

河对岸两个国家贫困县的历史,

并彻底改变当地人的交通状况。

一座桥横跨两岸并连接了吉明三省

四川和重庆三省交界处被称为吉明三省,这意味着只要村里有一只鸡叫,就可以听到三省的邻村。赤水河和渭河在这里相遇。这三个省分别悬崖三面。从历史开始,这个地方已经地理位置死亡,交通堵塞,旅行非常困难。

横跨赤水河支流回流河的建明三省大桥连接了叙永县水永乡渭河村和云南省昭通市镇雄县坡头镇德龙村。峡谷很深,水很湍急,悬崖很陡。它可以被描述为天蝎座。远远望去,一座拱桥横跨“U”形山谷和山脉,就像彩虹飞过河岸,气势磅.

吉明三省大桥于2016年建成四川都会大桥工程。该大桥采用二级公路等级,长度为286.4米。主跨是180米钢筋混凝土上支撑拱桥。双向双车道,两侧人行道,两侧总长1041.3米,总投资5900万元。

吊篮作为工具150米高的结构

桥的主拱从两侧延伸到中间,只留下中间的最后一段尚未关闭。 “这个长度约为2米。”施工人员告诉记者,早上7点,他们来到现场开工建设。

According to Jiang Zhongqiao, the construction unit and Sichuan Road and Bridge Project Manager, the geology of the bridge site is complex, and the excavation of the arch is large. The total excavation volume of the Sichuan and Yunnan shores is 120,000 square meters, and the construction area is in the scenic area of the Grand Canyon of the Three Provinces. In order to reduce the damage of vegetation, the construction workers used the construction cages to lift one basket and one basket and then transported them away.

This process is used because of poor parts, steep terrain, and difficult lifting.

The domestic arch bridge cantilever casting method was developed by Sichuan Highway Design Institute and was first applied to Baishagou No. 1 Bridge of Xipan Expressway in 2007. “The maximum cantilever pouring section of the Jiming Three Province Bridge has a weight of 239 tons, and the weight of the same type of arch bridge in China is the highest.” Design unit and Sichuan Highway Design Institute project leader Lu Xiaofeng said that the construction of the bridge is also the technology of the suspended arch bridge. Continue to study and develop in depth.

It is more convenient for the bridge to pass 2 and a half hours to 1 minute

Seeing that the main arch of the bridge is close to the dragon, it will soon be completed and opened to traffic. The local people are smiling and many people come to the scene to watch.

Sichuan’s Xuyong County and Yunnan’s Zhenxiong County are connected to the national poverty-stricken counties, and across the river from Qixingguan District, Bijie City, Guizhou Province. At present, there are bridges connecting the banks of Yunnan and Guizhou, and the banks of Sichuan and Yunnan are across the river. If you want to go to the other side, you need to drive for two and a half hours, or climb the mountain and cross the river for about one and a half hours. After the completion of the bridge, it will take only one minute to drive to the other side of the river, and the walk will be 300 meters, which will greatly save travel time and will completely eliminate the safety hazards of cross-strait residents' water passenger traffic.

Lutong will bring a better future. With the opening of this traffic bottleneck, Yunnan's coal, Sichuan's ice-clear Li, tobacco and other economic crops will be transported to the mountains more conveniently and quickly, helping the three provinces of the Grand Canyon tourism industry project to land, and boosting Wumeng The mountain people are lifted out of poverty.

xx交叉和换桥的特别推广明年年底基本消除车辆

作为省级公路过桥工程之一,济明三省大桥的建设是全省过境建设的缩影。我省有许多河流,经济欠发达地区的一些人不得不乘渡轮旅行。截至2013年底,全省共有1800多艘渡轮,给沿江人民的生产和生活带来了不便。为了解决群众的安全和便利,省委,省政府高度重视渡轮桥改造工程的建设,将其作为一项重大民生工程。

记者从四川省交通厅获悉,“十二五”以来,已建成487座公路桥梁,146座正在建设中。根据全省渡轮改造工程建设专项实施方案,计划到2020年底基本消除河道过境越野交通,年平均渡轮容量超过5万人。

2个半小时车程到1分钟,

这真是令人振奋的消息!

路通将带来更美好的未来。

随着山区瓶颈的开放,

交通会更方便,

各种特殊产品也可以更方便快捷地运输到山区,

帮助山区群众摆脱贫困。
