我的家乡是粤东红色革命老区的一个小山村，位于美丽的汀江河畔，一道蜿蜒两公里的堤坝守护了家乡 40余年。从懵懂少年迈入成熟中年，一切都在变，但不变的是那条堤坝在我脑海中的"红色"印记。她给 我永不磨灭的情怀和无穷的力量，激励我不断进取，努力交出优秀的答卷。 尽管阔别家乡多年，脑海中仍时常浮现这条堤坝将洪水阻拦于村外、守护百姓房屋和农田安全的情景。 这条"红色"堤坝诠释了团结一心、众志成城、无私奉献、攻坚克难的奋斗精神，并伴随我的成长，一直 激励着我不断努力进取。 为彻底治理洪灾，党和政府决定派一个由1000多人组成的农田基本建设团支援建设。为确保工程顺利实 施，公社任命父亲为大队党支部书记、大队长，开启了他为大队建设和村民服务的青春征程。 大学毕业后，我进入了生态环境系统工作，一干就是25年。无论在哪个岗位，我都时时以共产党员的标 准严格要求自己，在平凡的岗位上踏踏实实工作，全身心投入蓝天、碧水、净土保卫战。现在，年近50 岁的我又按照组织的安排，到了镇街一线工作，从事乡村振兴工作。我将埋头苦干，攻坚克难，努力将 这里的绿水青山变成金山银山，在启航新征程、奋进新时代中展现应有的风采，交出合格的答卷。 作者单位： ...

Core Viewpoint - The construction of the Nanjing Yangtze River Bridge symbolizes China's engineering capabilities and innovation, overcoming significant challenges to connect northern and southern transportation networks, and represents a monumental achievement in the nation's infrastructure development [3][5][12]. Group 1: Innovation and Technology - The Nanjing Yangtze River Bridge was the first large-scale bridge in China designed and constructed independently, breaking foreign predictions about the impossibility of building a bridge over the Yangtze River [3]. - The development of 16 manganese bridge steel, known as Q345C, was a significant technological achievement, resulting from collaboration between Anshan Steel Company and the bridge engineering team [3][4]. - The construction team innovated various techniques, including the creation of a 31.7-meter prestressed concrete beam and advanced technologies for steel wire control, achieving world-class standards [4]. Group 2: Teamwork and Resilience - The bridge construction faced numerous challenges, including severe flooding and structural instability, which required coordinated efforts and quick responses from the engineering team and workers [5][6]. - The construction team demonstrated exceptional bravery and commitment, with workers risking their lives to stabilize the bridge's foundations during critical moments [6][7]. - The dedication of the team was evident in their willingness to work under extreme conditions, including deep underwater operations that exceeded international safety limits [7]. Group 3: Quality and Management - The construction process emphasized meticulous attention to detail, with a focus on quality control and management practices that ensured the bridge's structural integrity [9][10]. - The engineering team implemented strict management systems, including responsibility and acceptance protocols, to maintain high standards throughout the construction [10]. - The bridge's construction utilized 66,500 tons of steel and 384,100 cubic meters of concrete, with a total cost of approximately 287.577 million yuan, reflecting the project's scale and resource management [11]. Group 4: Historical Significance and Legacy - The completion of the Nanjing Yangtze River Bridge in 1968 marked a significant milestone in China's infrastructure development, celebrated by the nation and symbolizing self-reliance and determination [12]. - The bridge has become a cultural icon, representing the spirit of innovation and perseverance, inspiring future generations to continue striving for excellence in engineering and construction [12].
