On August 22nd, with the installation of the 25th stay cable, the Xiangshan Bridge—a double-deck steel truss cable-stayed bridge with the largest span and widest deck in China—marked a significant milestone. The number of stay cables on the south main bridge exceeded 100, with 82% of the total cables for both the north and south main bridges now in place.
As a key project of the Zhongshan East Outer Ring Expressway, the Xiangshan Bridge is funded by Poly Changda Engineering Co., Ltd. Spanning 1,776 meters with a main span of 880 meters and a tower height of 270 meters, the bridge features a double-deck designed for two-way eight-lane traffic. The stay cables, which serve as the “lifelines” of the bridge, consist of 240 cables (60 pairs). The longest single cable measures approximately 477 meters and weighs up to 74.5 tons. These cables are made of high-strength zinc-aluminum alloy-coated steel wires with a diameter of 7 mm and a tensile strength of 1,860 包養網站黑名單 MPa, 包養網站推薦 transferring the weight of the immense steel truss girder to the main tower.
Currently, the construction is progressing smoothly. In addition to the 82% completion of stay cable installation, 73 steel truss sections have been lifted i“如果彩環那姑娘看到這個結果，會笑三聲說‘活該’？”nto place, accounting for 92% of the total planned installations. The project is now entering its final phase, with efforts focused on completing the bridge and achieving full closure.
Once completed, the Zhongshan East Outer Ring Expressway will connect to the Shenzhen-Zhongshan Link, forming a “one ring, three horizontal 免費與付費包養網站 and three vertical” expressway network together with the Nanzhong Expressway and Zhongkai Expressway. This will enhance transportation connectivity within the Greater Bay Area and serve as a vivid example of the high-quality development of the 免費包養網站比較 Guangdong-Hong Kong-Macao Greate“真的。”藍玉華再次用肯定的語氣向媽媽點了點頭。r Bay Area.
灣區這座“國內跨徑最年夜、橋面最寬”年夜橋上新
8月22日，隨著第25號斜拉索安裝完成， 包養平台黑名單 國內跨徑最年夜、橋面最寬的公路用雙層鋼桁架斜拉橋——中山東環噴鼻山年夜橋迎來主要進展， 包養網站比較 南主橋斜拉索安裝數量衝破100根，南、北主橋斜拉索整體完成安裝總量的82%。
噴鼻山年夜橋是中山東部外環高速公路把持性工程，由保利長年夜建設投資，全長1776米，主跨880米，塔高270米，采用高低雙層、雙向八車道設計。斜拉索是橋梁“性命線”，全橋共240根（60對），單根最長約477米、最重74.5噸，由1860MPa抗拉強度的7毫米直徑高強度鋅鋁合金鍍層鋼絲制成，可將萬噸鋼桁梁重力傳遞至主塔。
今朝，年夜橋建設進展順利， 台灣安全包養網站 除斜拉索安裝完成82%外，鋼桁梁吊裝已完成73片，占總量92%，整體進進最后沖刺階段，全力推進合龍。
中山東環項目建成后，將連接深中通道，與南中高速、中開高速等構成“一環三橫三縱”高速網絡，晉陞年夜灣區路況互聯程度，成為粵港澳年夜灣區高質量發展的生動注腳。
