公路隧道湿喷混凝土施工技术与研究

Study on Wet-Projected Concrete Construction Technology for Hi ghway Tunnel

为提高公路隧道初期支护的混凝土强度、减少回弹量、降低施工粉尘污染 ,在福建省漳龙高速公路乌石山隧道施工过程中 ,通过对初期支护的湿喷混凝土施工工艺的初步研究 ,提出了合理的施工配合比和施工工艺 ,在福建省漳龙高速公路如山头隧道、东家畲隧道。

Wet-projected concrete construction technology is used to enhance primary support strength during the Wushishan Tunnel construction, the reasonable construction mixing ratio and construction technology are put forward to raise concrete strength and decrease rebound modulus and dust pollution in highway tunnel primary support, which were widely used in Rushanton Tunnel, Dongjiashe Tunnel and Shikongshan Tunnel on Zhanglong Expressway in Fujian Province
