永泰至莆田段XPFJ-10标段隧道施工技术设计
摘 要
本毕业设计为向塘至莆田铁路工程永泰至莆田段XPFJ-10标段隧道施工技术设计。设计以新建铁路向蒲线永泰至莆田段站前工程修改初步设计（供招标用）设计图纸。建设单位组织的标前会议及补遗书、答疑书等有关内容和精神为基础，依据现行铁路隧道施工技术规范，对隧道总体施工组织布置及规划、施工准备、总体施工方案、施工方案方法及工艺、工程质量保证措施、施工安全保障措施和环境保护及水土保护措施等进行设计。隧道主体采用新奥法进行施工设计，初期支护采用锚喷支护，必要时加设辅助支护措施，衬砌型式采用复合式衬砌，并对各工序工作循环时间安排Ⅲ级围岩开挖与支护工作循环时间计算、各工序工作循环时间安排；结合交通量和隧道长度，采用双竖井配合射流风机通风，洞内排水为反坡排水时，采用集水坑分段收集，逐级抽排的方式排出；锚喷支护的关键控制点是混凝土喷射工艺、喷射设备的选型、锚杆设备的选型、成孔工艺及支护时机的把握等；由于隧道围岩地质条件较差，施工中，仰拱要先行，要及早封闭，以利于衬砌结构的整体受力。型钢钢架在洞外按设计加工成型，洞内安装在初喷砼之后进行，与定位锚杆联接。钢架间设纵向连接筋，钢架间用喷砼填平。钢架拱脚安放在牢固的基础上，架立时垂直隧道中线，当钢架和围岩之间间隙过大时要用喷砼填补。系统锚杆在围岩开挖和初喷混凝土后打设，钻孔时确保孔口岩面平整，使岩面与钻孔方向垂直，局部随机锚杆的孔轴方向与可能滑动面的倾向方向相反，其与滑动面的交角大于45°，间距1.0～1.5m，梅花形布置。锚杆注浆后，在砂浆凝固前，不敲击、碰撞和拉拔。严格遵守《建筑施工场界噪声限值》的有关规定，施工前，首先向环保主管部门申报并了解周围单位居民工作生活情况，施工作业严格限定在规定的时间内进行。隧道施工预防坍方首先要做好地质预报工作，掌握地质情况，选择安全、合理的施工方法和制定可靠的保证措施。在施工过程中要做到先排水、短开挖、弱爆破、强支护、快衬砌、勤检查、勤量测，及时处理隐患。应用先进的低噪音设备、改造设备器械声源及传递装置的工艺，控制声源振幅。塌方预防处理及应急预案, 塌方的处理技术措施, 开工前组织全体干部职工进行生态资源环境保护知识的学习，增强环保意识，保证环保工程质量，采取有效措施，使施工过程对生态环境的损害降低到最低程度；文明施工、文物保护。

ABSTRACT
This graduation design for pond to putian railway engineering yongtai to putian section XPFJ - 10 section of tunnel construction technology design. Design with new railway line to rush to yongtai putian section station project preliminary design modification (for bidding) design drawings. The construction unit organization scale before meeting and supplement books, answer books and other relevant content and spirit as the foundation, on the basis of the current railway tunnel construction technology standard, the tunnel construction organization overall layout and planning, construction preparation, overall construction plan, construction plan method and technology, engineering and quality assurance measures, construction safety measures and environmental protection and water and soil protection measures to carry on the design. The main tunnel new Austrian method for construction design, the primary support bolt-shotcrete support, when necessary, adding auxiliary support measures, lining type using composite lining, And of every working procedure work cycle time Ⅲ level surrounding rock excavation and support work cycle time calculation, the process working cycle time arrangement; Combined with traffic and tunnel length, with double shaft with jet fan ventilation, drainage hole for the slope drainage, the sump section collection, step by step to take a platoon way discharge; The key point is support by rockbolt and shotcrete technology, injection equipment selection, anchor equipment selection, pore forming process and supporting time grasp, etc.; Due to the tunnel surrounding rock with worse geological condition, the construction, the inverted arch to advance, to early closed for the whole lining structure stress.
