22、、编制原则1、斜井及通过斜井施工正洞段均为反坡排水,通过移动潜水泵将水抽至集水箱,再由集水箱抽至泵站排至洞外沉淀池,再由沉淀池排至河道内。2、在施工发生大涌水时,水量超出泵站的能力,将下坡段掌子面段作为临时水仓,但是必须保证施工人员及机械设备能够有及时撤离掌子面。3、如涌水量大,产生了灾难性的后果,在确保抢险人员生命安全的情况下,及时采取有效的抢救方案,减少人员伤亡程度,降低灾害损失,积极组织人力、物力、财力全力抢险救灾,处理涌水,尽快恢复正常施工生产。三、工程概况燕山隧道位于河北省张家口市境内,隧道起迄里程DK52+950DK74+106(右线YDK52+960YDK74+114),全长21

23、154m(右线21153m)。隧道为双洞单线隧道,最大埋深557m。洞内线路纵坡为5.1的单面坡,出口端位于曲线上,其余均位于直线上。燕山隧道4#斜井采用无轨运输双车道斜井,斜井平距1465m,斜长度为1472m。斜井与正洞交于DK64+300,夹角为49,斜井井口与井底高差为143.63m,从洞口到洞底每隔250m设置一处长度为25m、坡度为3%的缓坡段。 按照当前的隧道施工组织设计安排承担左线进口方向改DK63+407DK64+300段,长度893m的施工,左线出口方向改DK64+300DK65+042段,长度742m的施工;同时施工右线进口方向改DK63+413DK64+306段,长度8

24、93m的施工,右线出口方向改DK64+306DK65+060段,长度754m的施工。四、工程地质根据区内水文地质调查及对图纸资料的设计情况,区内地下水发育,涌水情况统计见下表。表1 4#斜井涌水量统计表序号里程正常涌水量Qst(m3/d)最大涌水量Qmax(m3/d)渗透系数(m/d)地质情况14斜14+654斜10+18/215.270.035新黄土,黄褐色,粉质粘土,粗圆砾土,卵石土,粗角斜长片麻岩,弱风化,(WT2-2)4斜4+004+75,(WT1-1)4斜4+854斜5+25,(WT2-3)4斜7+254斜7+55低阻异常段,呈散体状结构。24斜10+184斜8+6835010000

28、d,正常最大涌水总量为23000m3/d;正洞右线设计正常涌水总量为12500m3/d,正常最大涌水总量为25000m3/d。五、抽水形式选择斜井主排水采用2级泵站接力抽排的形式。为了防止突然大规模涌水或是停电造成的大型抽水设备、电力设施被水淹没,在距斜井井底120m处设置大型抽水站,并由高压电缆将洞外10KV高压电引入洞内,在抽水站旁设置大容量变压器1台。斜井与正洞交汇处设置集水坑,水经沉淀后由大流量单级离心泵抽至大型抽水站,最后由大型抽水机直接抽至洞外。六、设备选型及管路布置考虑施工期间的注浆止水等堵水措施的采取,施工期间的斜井及正洞的正常总水量按照10000m3/d考虑,即416.7m3

29、/h。斜井斜长度1472m,斜井井口与井底高差143.63m。排水管使用2趟200mm的排水管路(2趟200mm的高压风管为备用)。(1)、水站座泵选择在流量Q=416.7m3/h时,管路损失计算过程如下:V=Q/F=Q/r2=416.7(3.140.0013600)=3.68m3/s;V2/2g=3.68(29.81)=0.187m/s;H沿损失=L/DV2/2g=0.0214720.20.187=27.52mH局损失=(止回阀2个,约1%+90弯头1个,约3%)=1014%=4.04mH总损失=27.52+4.04=31.56m其中V:流速,Q:流量,F:管路截面积,:沿程阻力系数,L:管

30、路长度,D:管路直径。根据以上计算,水泵扬程应大于143.63m+31.56m-12.72=162.47m,选用4台D280-454型泵,流量Q=280m3/h 时,扬程H=180m,配用电机:N=220kW/380V,能满足要求。2台同时工作,1台备用,1台检修。(2)、井底水站水泵选择井底水站至大型抽水站坡段长度为120m,按照坡度为10.6%计算高差为12.72m,通过相同计算可知井底泵站配置150WQ-200-30-30型号,流量Q=200 m3/h 时,扬程H=30m的无堵塞潜水污水泵5台,3台工作,1台备用,1台检修。(3)、斜井及正洞施工排水平面布置图4#斜井及正洞施工排水平面布

31、置示意图七、水仓设置斜井最大设计涌水量为10000m3/d。水仓的容量根据设计文件,即水仓容量按30min的汇水量设计,30min的最大汇水量为208m3,抽水泵站水箱按20m2m3m=120m3,水箱旁设置4台D280-454型泵压水通过排水管路排至洞外沉淀池。井底集水仓容积按10m4m3m=120m3考虑,集水仓中间设置隔离墙(预留排水缺口),作为临时污水沉淀池,通过沉淀池流入至另一边的集水仓内,集水坑仓水通过150WQ-200-30-30型水泵吸水通过管路至大型泵站水箱,沉淀池设在斜井井底左侧10m位置,与排水管路同侧,便于清淤。抽水泵站平面布置图4#斜井井身泵站横断面及纵断面图4#斜井

32、井底集水坑及沉淀池图八、供电方案及应急供电方案由于抽水机都是大功率用电设备,洞内供电采用50平方高压电缆将洞外10KV高压电引入洞内,根据以上抽水机的配置抽水站需配置一台1250KVA的变压器。当网电停电后,应急电源的能力应能够满足排水、洞内照明需要,洞内必须保证2台220KW多级离心泵、3台30KW污水泵抽水,排水用电功率为530KW,照明20KW,共计550KW,根据以上计算,洞内设置双回路电源,备用1台800KW的发电机作为应急电源。由于停电后通风机无法工作,洞内没有新鲜空气供应,因此800KW发电机只能设置在洞外,通过洞外800KVA变压器向洞内变压器反送电。九、设备配置表表2 设备选

34、能存在涌水的地段前10m位置,实施超前地质探孔,探孔设置孔口管,并安装阀门。如果将地下水打漏,水量、水压很大,停止钻孔,关闭阀门,控制出水量,减小排水压力。根据水量、水压情况,及时通知相关各方,制定施工方案。每循环开挖钻眼过程中,采用5m长钻杆进行超前钻探,发现异常情况,及时停止开挖施工。采取超前地质探孔验证或采取帷幕注浆等施工方案。十一、成立涌水应急小组组织机构及职责1、应急小组成员及联系电话职务姓 名部 门联系电话备注组 长黄元庆行 政18932738877副组长王元俊党总支13333137599成员冯均明4#斜井副经理18932631622成员李海平办公室主任18932625222成员陈
