摘要
随着城市的发展,设置下穿式隧道成为缓解城市交通拥堵的必然措施之一。结合郑州市郑东新区龙源十三街隧道工程,对隧道外墙渗漏水情况进行了分析,并提出应对措施。详细介绍了隧道无对拉螺栓外墙施工工艺原理和工艺流程,以及混凝土灌注过程中外侧贝雷架变形验算。工程实践表明,该工艺有效地控制了隧道外墙的渗水,保证了隧道的正常运营。
With the development of city, setting underpass type tunnel is necessary to relieve traffic jam of city. Based on Longyuanshisanjie Tunnel engineering in Zhengdong New District of Zhengzhou, the authors analyze water leakage condition for exterior wall of the tunnel, and put forward countermeasures. The authors introduce construction principle and technological process of the exterior wall without split bolt, the deformation calculation of lateral bailey trusses during concrete pouring. Engineering practice shows that the construction process can effectively control external wall seepage, which ensures normal operation of the tunnel.
