[单选题] 各种气瓶的存放,必须保证安全距离,气瓶距离明火应在( -我要搜题网

某施工单位承担一立井井筒工程，该井筒净直径7．0m，井深580m。采用现浇混凝土支护，施工单位与建设单位指定的商品混凝土供货商签订了供货合同。由于施工场地偏僻，施工单位采购了压力试验机，建立了现场试验室，自行检验混凝土强度。在施工过程中，施工单位每50m井筒预留一组试块，在现场试验室经过标准养护28d后，自行进行强度试验。当井筒施工到井深500m时，发现上部井壁淋水加大，项目经理要求加快混凝土浇筑进度，待浇筑完该模混凝土后再处理上部井壁淋水，结果该模混凝土脱模后出现质量问题。检查发现，井壁严重淋水发生在井深450m附近。经调查，进行该段井壁混凝土浇筑时，供货商没有及时将混凝土送到，导致混凝土浇筑曾中断2次，前后耽误2h。经建设单位同意，施工单位对该段井壁进行了修复处理，投入费用20万元。井筒施工竣工验收时，建设单位要求对井壁混凝土进行破壁检查，每l00m检查一处，共6处，全部合格。

井筒工作面现浇混凝土时，处理上部淋水可采取哪些技术措施？

[填空题]

The first two stages in the development of civilized man were probably the invention of primitive weapons and the discovery of fire, although nobody knows exactly when he acquired the use of the latter.
41)______Animals have a few cries that serve as signals, but even the highest apes have not been found able to pronounce words, even with the most intensive professional instruction. The superior brain of man is apparently a necessity for the mastering of speech. When man became sufficiently intelligent, we must suppose that he gradually increased the number of cries for different purposes. It was a great day when he discovered that speech could be used for narrative. There are those who think that in this respect picture language preceded oral language. A man could draw a picture on the wall of his cave to show in which direction he had gone, or what prey he hoped to catch. 42)______
Two important stages came not so long before the dawn of written history. The fir
