Communication pipeline man hand hole downhole operation construction method
The invention discloses a communication pipeline man hand hole downhole operation construction method. The method includes the following steps that the construction axis, the position and the elevation of a man hand hole are retested; the influence quantity of the settling volume on all part structures of the man hand hole is estimated; bricks are checked and maintained; the man hand hole is dug,the hole is broached, accumulated water is drained, and an envelop structure is constructed; a ventilating cloth curtain is arranged; toxic gas is subjected to segmented sampling detection; and the strength of the envelop structure, the downhole oxygen quantity and the harmful gas residual quantity are regularly detected. According to the method, the structures of the man hand hole are correspondingly subjected to design treatment according to the estimated settling volume in order to reduce the influences of the settling volume, it can be guaranteed that the construction strength stability ofthe man hand hole is high, by means of the ventilating cloth curtain, gas in the man hand hole can be exhausted through natural wind in a circulating manner, and the downhole operation safety of construction staff is guaranteed.
本发明公开了一种通信管线人手孔井下作业施工方法，包括以下步骤：对人手孔的施工轴线、位置和标高进行复测；预估出沉降量对人手孔各部分结构的影响量；对砖材进行检查和养护处理；开挖人手孔，扩孔，积水排出，围护结构施工；设置通风布幔；有毒气体进行分段取样检测；定时对围护结构强度、井下氧气量和有害气体残留量进行检测；本发明方法通过根据预估出的沉降量对人手孔的结构进行相应的设计处理以降低沉降量影响，能够保证人手孔施工强度稳定性高，通过利用通风布幔可以利用自然风对人手孔内的气体进行循环排出，保证施工人员在井下的作业安全。
