(3)采用管棚法、新奥法短开挖、强支护、及时封闭围岩的方法通过破碎带二、巷道施工可能会遇到规模不同的溶洞，因此，施工中采取不同的支护是本工程的难点，为了保证安全施工采取以下施工方法：1、加强施工地质超前预报，及时了解施工工作面前方的围岩地质状况。发现有溶洞时，应根据地质探测情况，进行研究是超前释放、还是堵排结合的施工方法。2、堵填：对已停止发育、径跨较小、无水的溶洞，可根据其与巷道相交的位置及其充填情况，采用超前压浆、砼或浆砌片石预以回填封闭。拱部以上空溶洞，可视溶洞的岩石破碎程度采用锚杆加固，加设护拱及拱顶回填办法处理。3、跨越：当溶洞较大较深，不宜采用堵填封闭方法或充填物松软不能承载时，可采用梁、拱跨越办法，但梁端或拱座应置于稳固可靠的岩层上。4、施工中遇到一时难以处理的溶洞时，为了不使工程陷于停顿，一面用迂回导坑绕过溶洞区，继续进行巷道施工，一面处理溶洞。5、施工中应注意的事项：(1)在巷道施工前，应对地表进行详细勘察，注意研究岩溶状态，预测可能遇到溶洞的地段。(2)对地表水、出水点的情况要详细了解，地表应进行必要的处理，防止地表水下渗。(3)在掘进时，当凿岩机钻进速度变快时，可能已达到溶洞边缘，应注意观察水情变化及裂隙溶蚀程度，当有所增剧时，应对掘进、支撑、排水等工作加以妥善安排。(4)maintenancebusinessreception;(3)carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationenterprisebusinessorproductionmanagement;(4)Carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationenterprisetechnologymanagement;(5)carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationEnterprisecaraccessoriesmanagement;(6)carperformancedetectionEnterprisecarperformancedetectionandevaluation,anddetectionequipmentmaintenance;(7)cartransportenterprisecarusingmanagement;(8)insurancecompanyvehiclesaccidentsiteexploration;(9)carmanufacturingenterprisecarperformancedetectionanddebugging;2.getcertificatethisteachingplansaccordingtoMinistryofeducationhighvocationaldesignedprofessionaldirectoryprepared(Professionalcode:),andintegratedintotheMinistryoflaborandsocialsecurityallfourcarmechanicinthenationaloccupationalstandardsoccupationalfunctionsandskillrequirements,studentscompletingthiscourseundertheteachingplan,coredoublecertificatecoursescoreupto60pointsormore,...2....（2）Masterofmechanicaldrawing,engineeringmechanics,mechanics,automotivematerialsandprocessingtechnology,basicknowledgesuchasElectrotechnicsand53 当达到溶洞边缘、施工各工序应紧密衔接，同时设法探明溶洞的形状、范围、大小、充填物及地下水等情况，据此制定施工自理方案及安全措施。(5)施工中对溶洞顶板要经常检查，及时处理危石。当溶洞较大较高，顶板又较破碎时，应先进行喷射砼加固，必要时设置施工防护架或钢筋防护网。(6)在溶洞充填体中掘进，如充填物较松软，可用插板、插轨法或管棚法施工。如填充物为石块堆积，可在开挖前预压浆加固。第三节不良地质段巷道支护(一)不良地质巷道支护方法巷道支护按招标文件要求，设计为砼、喷射砼、不支三种方式进行支护。根据卡期特地形特征及当地的地形地貌，在巷道施工过程中可能会遇到（如溶洞、暗河、裂隙、断层、流沙、冒顶等）不良地质情况，施工中容易坍塌、冒顶、片帮，安全威胁大，根据不同岩石的稳定性采取超前导管注浆+钢拱架支护、超前锚杆+钢拱架支护、锚杆挂网喷砼支护、素喷砼支护四种方法进行初期支护，详见巷道支护施工断面图1、排水平巷双层超前导管注浆+钢支架支护(见图1)施工掘进中遇流沙层，涌水量大、易冒顶、坍塌的岩层，采用此支护方法进行初期支护。支护方法如下：（1）施工中突遇流砂时，应采取应急措施，在坑口备有沙袋、坑木，可随时调用，堵截流沙坍塌范围扩大。给支护施工带来困难。(2)在控制好流沙、冒顶、坍塌的岩层后，采用在设计开挖断面轮廓线外施作“超前注浆小导管(双层)+工字钢架+系统锚杆+钢筋网+喷C25砼”。(3)小导管采用φ50无缝钢管，施作于拱圈部，长度3.5m，仰角10度，分两层布置，排距及间距均为20cm，深入岩层底部1mmaintenancebusinessreception;(3)carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationenterprisebusinessorproductionmanagement;(4)Carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationenterprisetechnologymanagement;(5)carmaintenanceenterpriseorcarsalesandafter-salesserviceintegrationEnterprisecaraccessoriesmanagement;(6)carperformancedetectionEnterprisecarperformancedetectionandevaluation,anddetectionequipmentmaintenance;(7)cartransportenterprisecarusingmanagement;(8)insurancecompanyvehiclesaccidentsiteexploration;(9)carmanufacturingenterprisecarperformancedetectionanddebugging;2.getcertificatethisteachingplansaccordingtoMinistryofeducationhighvocationaldesignedprofessionaldirectoryprepared(Professionalcode:),andintegratedintotheMinistryoflaborandsocialsecurityallfourcarmechanicinthenationaloccupationalstandardsoccupationalfunctionsandskillrequirements,studentscompletingthiscourseundertheteachingplan,coredoublecertificatecoursescoreupto60pointsormore,...2....（2）Masterofmechanicaldrawing,engineeringmechanics,mechanics,automotivematerialsandprocessingtechnology,basicknowledgesuchasElectrotechnicsand53
