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(shí)的基礎(chǔ)。

　  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(zhǎng)570米，主跨200米，最高墩達(dá)62米，為特大跨連續(xù)剛構(gòu)橋。大橋所在地南哨鎮(zhèn)是斜坡地帶，境內(nèi)溝壑縱橫，切割劇烈，山體陡峭、峽谷高差大，且為國(guó)家闊葉林保護(hù)區(qū)核心區(qū)域，具有人員高空作業(yè)和掛籃施工安全風(fēng)險(xiǎn)高、生態(tài)保護(hù)級(jí)別高等特點(diǎn)。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(gòu)橋中的極限設(shè)計(jì)，施工安全、質(zhì)量管理難度較大，項(xiàng)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(kāi)通便道、架設(shè)橋梁實(shí)屬不易?！表?xiàng)目組負(fù)責(zé)人表示，因需要大跨徑涉河橋梁施工，便道修筑、材料運(yùn)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(xiàng)目自制“拖船”轉(zhuǎn)運(yùn)機(jī)械設(shè)備，用小駁船“螞蟻搬家”式運(yùn)轉(zhuǎn)材料及施工機(jī)具，克服極端天氣及材料運(yùn)輸困難，才確保了施工順利推進(jìn)。

　 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(shè)過(guò)程中，項(xiàng)目部注重安全和成本管控，牢固樹(shù)立“雙控”模式、“穩(wěn)”字當(dāng)頭的施工管理理念，合理優(yōu)化施工方案，多次開(kāi)展技術(shù)攻關(guān)，將1項(xiàng)施工工法、2項(xiàng)專(zhuān)利、2項(xiàng)QC等運(yùn)用到橋梁施工中，為大橋成功合龍、6月底通車(chē)奠定了堅(jiān)實(shí)基礎(chǔ)。 據(jù)了解，貴州劍榕高速公路線路全長(zhǎng)116.45公里，橋隧比高達(dá)78%。是由公司承建劍榕五標(biāo)項(xiàng)目主要工程為停車(chē)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(chē)時(shí)間將比現(xiàn)在縮短約1.5小時(shí)，對(duì)于打通貴州省東南部區(qū)域?qū)ν饨涣骺旖萃ǖ?，帶?dòng)沿線經(jīng)濟(jì)發(fā)展具有重要意義。
