Description

TBM隧洞混凝土喷射的滑模施工***及方法 技术领域
本发明属于工程隧洞喷射混凝土支护技术领域，尤其涉及TBM隧洞混凝土喷射的滑模施工***及方法。
背景技术
目前，敞开式TBM隧洞普遍采取钢支撑、钢筋排、锚杆、钢筋网以及喷混凝土等支护手段，而喷混凝土是其支护的重要环节。随着技术的进步，通常是依靠TBM设备上搭载的喷混凝土机械手来完成。虽然技术十分成熟，机械化程度也非常高，但实践中也存在一些不容忽视的问题，一直困扰着技术工作者。主要表现在：
1、喷混凝土作业时出现较大粉尘，工作环境较差；即便是采用先进的湿喷设备，也很难得到实质性改观，严重威胁职业健康。
2、喷混凝土作业时混凝土回弹率过高，一般情况下高达到30％以上，尤其是拱顶、渗水、破碎围岩等部位混凝土回弹率甚至更高，浪费了较多的混凝土材料，在加大了工程成本的同时，增加了清理工作量，不利于文明施工管理。
3、喷混凝土作业效率与TBM开挖速度不十分匹配，对于喷混凝土厚度较大时，需分多次、多层实施才能达到设计厚度，占用了较多的工序时间，制约TBM效率的发挥，对施工进度带来一定影响。
4、喷混凝土厚度不均匀、强度达标难、表面不平整、质量不稳定等是喷射混凝土作业的质量通病，严重时威胁隧洞安全使用。
发明内容
针对上述传统喷混凝土支护工艺存在的不足，本发明提供TBM隧洞混凝土喷射的滑模施工***及方法，此***结合敞开式TBM隧洞开挖速度与支护速度不十分匹配的实际，借鉴模喷混凝土和隧洞滑模技术，设计提供一套周向滑动模板，搭载到开敞式TBM设备上，与TBM自带的喷混凝土***有机结合起来，实现滑模喷射混凝土功能，弥补现有技术的不足，从而达到改善作业环境、提高支护效率、增强支护效果、提升支护质量、节约工程成本、方便平行作业、减少清理工作、有利文明施工、与TBM开挖效率相匹配的目的。

采用TBM隧洞混凝土喷射的滑模施工***进行隧洞混凝土喷射施工的方法，包括以下步骤：
步骤一，滑模施工***制作：
根据整个滑模施工***的结构，如果利用已有TBM加装或改造，委托专业生产厂家实施，必须与TBM的混凝土喷射***相匹配，如果与TBM同步制造，则与喷混凝土***密切结合起来，考虑公用环形梁和旋转框架，实现滑模和喷射混凝土一体化；
步骤二，滑模施工***安装：
将制作好的滑模施工***的***部件与TBM进行组合安装，安装完成之后，无论是改造加装或是直接携带，均需专业厂家安装并调试，必须与TBM、喷混凝土机械手功能相匹配；
步骤三，喷混凝土施工：
利用混凝土喷射机通过机械手带动喷砼嘴将混凝土喷射到弧形模板与开挖岩面之间的缝隙内，其过程严格按照分层、分次逐步将模板喷满，尔后再边旋转模板***边喷灌混凝土，其过程严格执行分层均匀喷射、同步滑升的原则；如此自下而上、循环渐进的完成混凝土喷射施工；当施工至拱顶封顶部位时，考虑到施工方便，直接采取喷混凝土封堵；
步骤四，模板***的旋转滑升：
模板***的初次滑升要缓慢进行，并在此过程中，对旋转滑动***，模板***以及相关设施，在负载情况下，全面***检查，发现问题，及时处理，待一切正常后方可进行正常滑升；两边拱段随着滑模的模板***的滑升其速度逐渐减慢，尤其滑升进入腰部后和拱顶段后，其速度应严格控制，应尽量保持连续作业，须由专人观察脱模混凝土表面质量，以确定合适的滑升时间和滑升速度，这需要根据混凝土特性、供料速度、环境温度、脱模强度综合试验来确定；
步骤五，混凝土的消缺养护：

当模板***滑到拱顶封顶部位封堵完成并待强具备脱模强度后，启动升降脱模***的伸缩油缸，使模板***与混凝土脱离；尔后启动旋转滑动***将模板***旋转至两侧，再启动平移***向前移动至下一个仓号；如此循序往返，逐渐完成隧洞混凝土支护施工。
步骤三中喷混凝土施工过程中，对混凝土的水灰比、塌落度和速凝剂特性要求严格，必须在工艺实施前通过严格的实验来选取合适的混凝土指标，以满足混凝土运输、喷射入仓、滑动、脱模要求；
滑模施工过程中，直接将混凝土喷射到模板与开挖岩面之间的空间内，实现边喷射混凝土、边滑动模板、边脱模、边养护连续作业；
当设备就位、材料到位、人员到岗的准备工作就绪后，隧洞两侧的两组模板***随之就位，端头封堵完成，开始实施喷射混凝土，喷混凝土自隧洞两侧270度位置开始进行；通常采用一台混凝土喷射***从隧洞两侧交替喷射作业即可，当工程量大、强度要求高时，采用两台混凝土喷射***从隧洞两侧同步进行；喷射混凝土必须自下而上分层分次进行，首次喷射必 须分层喷射充灌密实后，再边滑升300mm、边喷灌混凝土，通过旋转滑动把混凝土挤压到岩面上，这样自下而上逐步完成一个循环的喷混凝土作业，脱模后再通过平移***移至下一个仓号作业，如此循序渐进的完后才能滑模喷混凝土连续作业。
本发明有如下有益效果：

进一步的，所述支撑***1包括TBM本体102，所述TBM本体102的内部搭载有喷砼车连接桥101；所述TBM本体102通过轨道轮装置104滚动支撑在TBM轨道103上。
其中支撑***1是该滑模装置的骨架，也是模板、旋转、滑动、平移、升降、脱模***的支撑构架，其主要利用TBM上喷混凝土喷砼车连接桥101作为支撑。
进一步的，所述平移***4包括齿条402，所述齿条402固定在支撑***1的喷砼车连接桥101上；所述齿条402与第一齿轮403啮合传动，所述第一齿轮403固定安装在第一液压马达404的输出轴上，所述第一液压马达404固定安装在旋转滑动***3上，所述喷砼车连接桥101上安装有直线滑轨401，所述直线滑轨401与旋转滑动***3上的滑移座306构成滑动配合。其中平移***4是模板沿隧洞轴线前后行走的装置，安装在喷砼车连接桥101上，可利用喷混凝土机械手的平移齿条，通过液压马达、减速机驱动、齿轮齿条传动完成旋转框架的前后移动，实现混凝土喷射位置在隧洞轴线方向上的定位和行走，其行走速度与喷混凝土机械手相匹配，驱动力需经过计算得到。
进一步的，所述旋转滑动***3的结构与TBM内部的喷混凝土机械手的旋转滑动系 统相同；所述旋转滑动***3包括环形梁301，所述环形梁301通过滑移座306滑动支撑在支撑***1的喷砼车连接桥101上；所述环形梁301上安装有齿圈305，所述齿圈305与第二液压马达303输出轴上的第二齿轮304啮合传动，所述第二液压马达303固定安装在旋转框架302上，所述旋转框架302通过滑块与固定在环形梁301上的环形滑轨307构成滑动配合；所述旋转框架302上搭载升降脱模***6。上述的旋转滑动***3是模板环向旋转的关键，环形梁301、齿圈为定型产品，可根据隧洞特征定制，并可参照喷混凝土机械手的环梁形式，齿圈固定在环形梁301上；模板固定在在旋转框架302上，旋转小车为模板环向滑动提供动力，其齿轮与齿圈相匹配；旋转小车带动旋转框架302通过液压马达、减速机驱动、齿轮齿圈沿环形梁环向旋转，实现边滑动、边喷混凝土功能。其旋转速度与喷混凝土速度相匹配，旋转力矩需通过计算选取，计算时要统筹考虑滑动摩阻力、混凝土侧压力，并充分考虑其安全系数。
进一步的，所述旋转框架302共有两组，并相对独立设置在环形梁301上。通过采用两组在一定程度上提高了施工效率。
进一步的，所述升降脱模***6包括固定在旋转滑动***3的旋转框架302上的伸缩油缸601，所述伸缩油缸601的输出轴安装有导向杆603，所述导向杆603上套装有压紧弹簧602；所述模板***2固定在导向杆603的顶端。当拱顶混凝土封堵完成并待强后，既可以脱模；脱模通过液压伸缩油缸来实现，伸缩油缸的行程、最大推力综合考虑混凝土侧压力、摩阻力等因素。伸缩油缸安装在滑动框架与模板之间，并设置有导向装置及弹簧，以适应滑模工况的变化。
滑模装置通过前后行走装置、环向旋转装置、滑模升降装置来定位、移动、滑动、脱模，从而实现滑模功能。在滑模前后和环向均设置有混凝土喷嘴，可根据喷混效果调整喷嘴位置。必要时，可安装搭接滑模和搭接支架，以加大模板尺寸。

步骤五，混凝土的消缺养护：

步骤三中喷混凝土施工过程中，对混凝土的水灰比、塌落度和速凝剂特性要求严格，必须在工艺实施前通过严格的实验来选取合适的混凝土指标，以满足混凝土运输、喷射入仓、滑动、脱模要求；
