On May 11, Nanshao River Bridge, another controlled project of Guizhou Jianrong Expressway, was successfully closed, laying a solid foundation for the overall completion of Jianrong Expressway.

    5月11日，貴州劍榕高速公路又一控制性工程南哨河特大橋順利合龍，為劍榕高速公路的全面完工打下了更為扎實的基礎。

　  It is reported that the Nanshao River Bridge has a total length of 570 meters, a main span of 200 meters and a maximum pier of 62 meters. Nanshao Town, where the bridge is located, is a sloping area with vertical and horizontal ravines, severe cuts, steep mountains and large canyon height differences, and is the core area of the National Broad-leaved Forest Reserve. Advanced features. In addition, the Nanshao River Bridge spans the 100-meter-deep "U"-shaped canyon of the Nanshao River. It is the ultimate design of the highway rigid-frame bridge currently under construction. Construction safety and quality management are difficult. The project team and the whole work Despite the pressure, the staff still won the final victory. "It is not easy to open access roads and erect bridges between the mountainsides that are close to the cliffs." The person in charge of the project team said that due to the need for the construction of large-span river-crossing bridges, the construction of access roads and the transportation of materials are facing great difficulties.
    據(jù)悉，南哨河特大橋全長570米，主跨200米，最高墩達62米，為特大跨連續(xù)剛構橋。大橋所在地南哨鎮(zhèn)是斜坡地帶，境內溝壑縱橫，切割劇烈，山體陡峭、峽谷高差大，且為國家闊葉林保護區(qū)核心區(qū)域，具有人員高空作業(yè)和掛籃施工安全風險高、生態(tài)保護級別高等特點。并且，南哨河特大橋橫跨南哨河百米深的“U”型峽谷，是目前在建高速公路剛構橋中的極限設計，施工安全、質量管理難度較大，項目組及全體工作人員頂著十足的壓力，依然取得了最終勝利。“在幾近懸崖的山腰間開通便道、架設橋梁實屬不易?！表椖拷M負責人表示，因需要大跨徑涉河橋梁施工，便道修筑、材料運輸都面臨著很大困難。

　  In order not to be stuck in the neck, the project made a self-made "tugboat" for transporting machinery and equipment, and used a small barge to move materials and construction equipment in an "ant moving" style to overcome extreme weather and material transportation difficulties to ensure the smooth progress of the construction.
   為了不被卡脖子，項目自制“拖船”轉運機械設備，用小駁船“螞蟻搬家”式運轉材料及施工機具，克服極端天氣及材料運輸困難，才確保了施工順利推進。

　 During the construction process, the project department paid attention to safety and cost control, firmly established the construction management concept of "dual control" mode and the word "stability", rationally optimized the construction plan, carried out technical research many times, and obtained 1 construction method and 2 patents. , 2 items of QC, etc. were applied to the bridge construction, which laid a solid foundation for the bridge's successful closure and opening to traffic at the end of June. It is understood that the total length of the Jianrong Expressway in Guizhou is 116.45 kilometers, and the bridge-tunnel ratio is as high as 78%. The company undertakes the construction of the Jianrong Five Standard Project. The main projects are 1 parking area, 6 bridges, and 3.5 tunnels. As an important part of the "678" expressway network in Guizhou Province, the "second longitudinal" along the river to Rongjiang expressway, after the completion of the project, the travel time from Jianhe to Rongjiang will be shortened by about 1.5 hours compared with the current one. It is of great significance to promote the economic development along the route as a fast channel for regional external exchanges.
   建設過程中，項目部注重安全和成本管控，牢固樹立“雙控”模式、“穩(wěn)”字當頭的施工管理理念，合理優(yōu)化施工方案，多次開展技術攻關，將1項施工工法、2項專利、2項QC等運用到橋梁施工中，為大橋成功合龍、6月底通車奠定了堅實基礎。 據(jù)了解，貴州劍榕高速公路線路全長116.45公里，橋隧比高達78%。是由公司承建劍榕五標項目主要工程為停車區(qū)1處、橋梁6座、隧道3.5座等。作為貴州省“678”高速公路網(wǎng)“第二縱”沿河至榕江高速公路的重要組成部分，工程建成后劍河至榕江行車時間將比現(xiàn)在縮短約1.5小時，對于打通貴州省東南部區(qū)域對外交流快捷通道，帶動沿線經(jīng)濟發(fā)展具有重要意義。
