摘要
在巷道长距离掘进施工技术中形成的独头巷道,无法形成贯穿风流,导致巷道的内的气体很难被快速散尽,从而无法达到施工要求,并严重影响到工程施工的进度。在深井长距离斜坡道独头掘进通风中,由于长距离通风的风阻比较大,且漏风严重,难以保证通风质量,为了满足工程施工要求,针对以往施工中掘进通风中存在的问题进行改善,有利于提供通风质量,确保施工进度。基于此,本文就深井长距离斜坡道独头掘进通风中存在的问题进行深入分析,并提出针对性的解决措施,为后续施工提供必要的参考借鉴。
The single ended tunnel formed in the long-distance excavation construction technology of the tunnel cannot form a continuous airflow,which makes it difficult for the gas inside the tunnel to be quickly dissipated,thus failing to meet the construction requirements and seriously affecting the progress of the project construction.In the ventilation of single head excavation of deep and long-distance inclined slopes,due to the high wind resistance and severe air leakage of longdistance ventilation,it is difficult to ensure ventilation quality.In order to meet the requirements of engineering construction,improvements have been made to address the problems existing in previous excavation ventilation,which is conducive to providing ventilation quality and ensuring construction progress.Based on this,this article conducts an in-depth analysis of the problems existing in the ventilation of single end excavation of deep wells and long-distance inclined ramps,and proposes targeted solutions,providing necessary reference for subsequent construction.
