(接上期)联络通道及泵房施工方法、工艺及技术措施本标滨江新城站~开福寺站区间共设6个联络通道(含1个废水泵房),联络通道4~#~7~#采用全断面注浆,其他联络通道采用管片背后注浆,如施工中发现地下水发育,开挖可能引起突水涌泥或地下水,地表水流失,征得设计同意后也可参照全断面注浆设计。滨江新城站~开福寺站区间联络通道分布如附表所示。联络通道施工联络通道首先在管片上开口然后采用矿山法开挖,并采用复合式衬砌。施工步骤是:管片
(Connected to the previous period) liaison channel and pump room construction methods, techniques and technical measures The standard Binjiang New City Station ~ Kaifu Temple Station a total of six contact channels (including a waste water pump room), the contact channel 4 ~ # ~ 7 ~ # Full-face grouting is adopted. Other contact channels are grouted behind the pipe segments. If groundwater is found during construction, excavation may cause sudden water bursting or groundwater loss and surface water loss. After obtaining the design consent, refer also to the full-face note Slurry design. Binjiang New City Station ~ Kaifu Temple Station Inter-channel distribution as shown in the attached table. Contact channel Construction of the first channel in the pipe opening and then mining method of excavation, and the use of composite lining. Construction steps are: pipe pieces
