立井施工采用短段掘砌混合作业方式,是自鸡西建井处施工杏花立井和七煤集团公司建设工程总公司施工桃山、新兴立风井后逐步发展成熟起来的一项立井施工新技术。此种技术的应用与推广,有效地提高了立井施工的速度和经济效益。同时,我们也发现了一些缺点和问题,针对这些缺点和问题,我们在施工中对大段高模板进行了逐步改进,改进后的使用效果证明了我们的改进工作是合理有效的,现将我们主要的改进工作总结如下:
Vertical well construction using short excavation and mixing operation mode is constructed from the Jixi Xing Fa wells and the Seventh Coal Corporation Construction and Engineering Corporation Construction Peach Hill, a new vertical shaft after the gradual development and maturity of a shaft construction of new technologies. The application and promotion of such technologies have effectively raised the speed and economic benefits of shaft construction. At the same time, we also found some shortcomings and problems. In response to these shortcomings and problems, we gradually improved the large-size high-profile formwork during construction. The improved use result proves that our improvement work is reasonable and effective. Now, we The main improvement work is summarized as follows:
