潘广路电力隧道三标项目涵盖4个工作井,区间长度达1100m,隧道底部填仓用混凝土有极高的外观质量,满足强度的条件下需达到混凝土表面不起皮不起砂的外观要求,同时对隧道区间实际情况,混凝土水平泵送必须满足至少500米要求,而且兼顾经济性,以此通过使用常规常用材料配置中长距离泵送混凝土,完善施工工艺,防止堵泵,最终在项目上得到成功运用。
Pan Guang Road power tunnel three standard projects include four working wells, the interval length of 1100m, the bottom of the tunnel with a very high filling quality of the appearance of concrete, to meet the strength of the concrete surface can not afford to meet the appearance of the skin can not afford sand, at the same time For the practical situation in the tunnel section, the level of concrete pumping must meet the requirements of at least 500 meters, and take into account the economy, in order to use the common materials commonly used in the configuration of long-distance pumping concrete, improve the construction process to prevent plugging pump, and ultimately get on the project Successful application.
