特大型箕斗装载硐室快速施工技术

Rapid construction technology of extra-large skip loading chamber

为加快红庆河煤矿主立井箕斗装载硐室施工速度,根据特大型箕斗装载硐室断面大、结构复杂、施工难度大的特点,硐室施工采用分段、分层掘进,锚网索喷复合支护,模板拱腿进行图形定位,并根据定位进行材料计划和加工。通过合理安排施工顺序、加强施工组织及施工准备阶段图形定位技术的应用,简化了施工工序,实现了工程安全、保质、快速施工,对类似条件特大型装载硐室施工具有一定借鉴意义。

In order to speed up the construction of Hongqinghe main shaft skip loading chamber, according to the characteristics of the large-scale skip-loading chamber with large, complicated structure and difficult construction, segmented, stratified excavation and bolt-mesh-cable compound support were carried out and template arch was applied for graphical positioning. And the material was planned and processed according to the positioning. Through the reasonable arrangement of the construction sequence, application of the graphic positioning technology in construction organization and preparation, the construction process was simplified, the engineering safety, durability and rapid construction were achieved.
