Description

一种用于超深竖井开凿过程中的排水系统及排水方法 技术领域
本发明涉及竖井施工技术领域，具体涉及一种超深竖井开凿过程中的排水系统及排水方法。
背景技术
一般认为：深度在300米内的竖井为浅竖井，300-600米为中深竖井，600-1000米为深竖井，1000米以上为超深竖井。
井壁淋水顺井壁流入竖井井底工作面，爆破后竖井裸壁的涌水流入工作面，现有的排水方法是在井底工作面设置集水坑，采用扬程40-70m 3/h的电动排污泵排水到吊盘的水箱中(体积2m 3-5m 3)，再由吊盘上安装高扬程水泵排水到地面，高扬程水泵虽然可以将水从井内排出，但是高扬程水泵的平面尺寸大(达到4*1m)，重量大(达到3吨以上)，对直径8m以下的深竖井施工时，在吊盘上占用空间大，重量偏离吊盘重心较大，吊盘悬吊钢丝绳强度和直径要求高，施工中吊盘受力不平衡，对施工安全造成影响，这种泵需要与生产厂家协商定制，水泵生产周期较长，一旦损坏，维修难度大，而且严重影响竖井施工工期。
发明内容
针对现有技术中存在的问题，本发明提供一种用于超深竖井开凿过程中的排水系统，包括用于将竖井工作面的水抽出的第一泵，竖井的壁上设置有接水站，接水站内设置有用于存储竖井工作面的水的储水仓，接水站内还设置有用于将储水仓内的水抽取并输送至竖井外的第二泵。
在上述方案的基础上，还包括设置在竖井内的吊盘上的水箱和用于将水箱中的水抽取并输送至储水仓的第三泵；所述水箱用于接收第一泵抽取的工作面的水。
在上述方案的基础上，所述储水仓还用于接收接水站以上的竖井井壁淋水。竖井井壁淋水使用截水装置收集；所述截水装置包括绕竖井井壁设置的截水槽和用于将截水槽内的水输送至储水仓的输水管。
在上述方案的基础上，所述储水仓包括沉淀水仓和净水水仓；所述沉淀水仓用于接收竖井工作面的水并将水中的泥沙进行沉淀；所述净水水仓用于接收沉淀水仓沉淀泥沙后的水；所述第二泵用于抽取净水水仓内的水并将水输送至竖井外。
本专利还提供一种超深竖井开凿过程中的排水方法，在竖井的壁上挖掘一个接水站，接水站内设置有用于存储竖井工作面的水的储水仓，接水站内还设置有用于将储水仓内的水抽取并输送至竖井外的第二泵，排水时，打开设置于竖井工作面的第一泵，将竖井工作面的水抽取并输送至储水仓内，再由第二泵将水从储水仓抽取并输送至竖井外。当第一泵与接水站之间的高度差过大时，在竖井内的吊盘上设置水箱，同时增加将水箱中的水抽取并输送至储水仓的第三泵。
本发明的通过设置接水站、储水仓和第二泵，可以有效降低对竖井排水水泵的性能(扬程和功率)要求，还可以降低对悬吊吊盘钢丝绳强度和直径的要求，从而减少设备成本。排水泵体积和重量的减小，有利于吊盘上设备和悬吊点的布置，使其受力相对平衡，减少安全方面的影响。降低扬程，有利于选择排水能力较大的水泵。设置中间转水站，利于污水沉淀，改善排水泵工况，减低排水泵维修量和故障率。

具体实施方式
现列举以下实施例用来说明本发明所述的技术方案。需要说明的是，以下实施例对本发明要求的保护范围不构成限制作用。
实施例1
如图1所示，一种用于超深竖井开凿过程中的排水系统，包括用于将竖井工作面的水抽出的第一泵8，竖井的壁上设置有接水站1(接水站1是在竖井的壁上进行横向挖掘得到的)，接水站1内设置有用于存储竖井工作面(即：井底)的水的储水仓4，接水站1内还设置有用于将储水仓4内的水抽取并输送至竖井外的第二泵5。第一泵8可以使用涡轮式风 动排污泵，以压缩空气为动力，可以有效解决电动排污泵的漏电风险。接水站1和第二泵5的设置可以有效降低对排水设备性能的要求。如果竖井内的涌水量大，可以增加第二泵5的数量。
随着竖井的深度不断加大，当第一泵8与接水站1之间的高度差过大时，可以在竖井内的吊盘7上设置水箱2，同时增加将水箱2中的水抽取并输送至储水仓4的第三泵3；所述水箱2用于接收第一泵8抽取的工作面的水。如果以接水站1作为一个固定的接力点，那么，水箱2和第三泵3的设置，就可以理解为是一个活动的接力点，这一个固定的接力点配合一个活动的接力点，可以更为有效的减少对排水设备性能的要求，同时，随着竖井挖掘深度的不断增大(比如达到1600m以上)，无需再增设新的接水站。
竖井工作面的水主要有两个来源，一个是工作面的涌水，一个是井壁的淋水，对于井壁淋水，如果都汇集到井底的工作面，不但会增大工作面的水量，还增大了排水的工作量，为了解决这一问题，作为一个具体的实施方案，在上述方案的基础上，可以将位置在接水站1上部(即：高度高于接水站1)的竖井井壁淋水直接引导至储水仓4内，具体可以使用截水装置6，截水装置6可以将接水站1以上的竖井井壁淋水汇集并引导至储水仓4内，
如图1和2所示，所述截水装置6包括绕竖井井壁设置的截水槽6-1和用于将截水槽6-1内的水输送至储水仓4的输水管6-3，截水槽6-1上设置有出水口6-2，截水槽6-1截流的水会通过出水口6-2进入输水管6-3，最终进入储水仓4。布设截水槽6-1时，远离出水口6-2的一侧的高度高于出水口6-2一侧的高度，使截水槽6-1整体向出水口6-2的一侧倾斜，便于淋水的流出。
目前，截水槽有很多种类，比如使用槽钢固定在竖井壁上或者直接在竖井壁上开凿出截水槽等，但是这些方式的截水槽存在很多问题，比如使用槽钢会因为槽钢的重量过大，安装时工作量比较大且风险比较高，同时优于井壁是弧形的，槽钢的刚性很难与井壁卡合，再比如直接在竖井壁上开凿出截水槽，这种方式会破坏井壁的防护层(混凝土层)，而且施工成本比较高。针对现有的问题，本专利提供一种新型的截水槽，材料优选使用塑料(比如高密度聚乙烯HDPE或聚丙烯PP)，这种材料硬度可以达到要求同时还带有一定的弹性，安装时可以允许随着井壁的弧形有一定的变形，具体结构上，如图2、图3、图4和图5所示，所述截水槽6-1由若干个截水槽模块6-11插接而成；所述截水槽模块6-11为U形(U型的底部面可以是平面也可以弧面)，其中一个侧壁用于将截水槽模块6-11固定在竖井井壁上(固定可以使用膨胀螺栓)；截水槽模块6-11的一端为接收端(如图3的左侧端)，另一端为插入端(如图3的右侧端)；一个截水槽模块6-11的接收端用于与它相连接的一个截水 槽模块6-11的插入端插入，同时它的插入端用于插入与它相连接的另一个截水槽模块6-11的接收端(如图5所示)。
截水槽在安装时是直接在竖井壁上进行固定安装，为了更方便的进行安装，所述截水槽模块(6-11)的接收端和插入端均从端部向中心部逐渐变厚，同时，接收端的起始处厚度比插入端的起始处的厚度大。这种设置，可以直接将一个截水槽模块的接收端套在已经安装在井壁上的截水槽模块的插入端(已经安装在井壁上的截水槽模块的插入端与井壁之间存在一定的间隙)，也可以直接将一个截水槽模块的插入端插入到已经安装在井壁上的截水槽模块的接收端，实现两侧随意安装，安装方便，同时便于两个截水槽模块之间进行密封。
为了防止截水槽6内的水从两个截水槽模块6-11之间流出，所述截水槽模块6-11的接收端的内壁设置2条并行的内凹的密封槽6-12，密封槽6-12内用于安装密封条；截水槽模块6-11的插入端的外壁上设置1条凸起的密封凸6-13；如图5所示，两个截水槽模块6-11插接在一起时，一个截水槽模块6-11的密封凸6-13位于另一个截水槽模块6-11的2个密封槽6-12之间，通过两个安装在密封槽6-12内的密封条夹住密封凸6-13，实现两个截水槽模块6-11之间的密封。
因为竖井的井壁并非是一个光滑的壁，如果直接将截水槽模块6-11固定在井壁上，会在截水槽模块6-11与井壁之间存在一定的间隙，减弱了截水的效果，为了解决这一问题，作为一种实施方案，如图3所示，在所述截水槽模块6-11靠近竖井井壁侧的侧壁外部设置有弹性板6-4，弹性板6-4的材料可以使用橡胶板，将截水槽模块6-11固定在竖井井壁上时，会对弹性板6-4进行压缩，从而有效的减少截水槽模块6-11与井壁之间的间隙，达到很好的截水效果。
上述结构的截水槽模块6-11优选使用注塑一体成型的方式制备。
竖井工作面的水中有很多泥沙，为了减轻泥沙对泵的损坏，如图6所示，所述储水仓4包括沉淀水仓4-1和净水水仓4-2；所述沉淀水仓4-1用于接收竖井工作面的水并将水中的泥沙进行沉淀；所述净水水仓4-2用于接收沉淀水仓4-1沉淀泥沙后的水；所述第二泵5用于抽取净水水仓4-2内的水并将水输送至竖井外。同时，进入吊盘7上的水箱2中的水也可以先在水箱2中进行沉淀，再通过第三泵3将水抽至沉淀水仓4-1内。
实施例2
基于实施例1的排水系统，本实施例提供一种超深竖井开凿过程中的排水方法，具体的，在竖井的壁上挖掘一个接水站1，接水站1内设置有用于存储竖井工作面的水的储水仓 4，接水站1内还设置有用于将储水仓4内的水抽取并输送至竖井外的第二泵5，排水时，打开设置于竖井工作面的第一泵8，将竖井工作面的水抽取并输送至储水仓4内，再由第二泵5将水从储水仓4抽取并输送至竖井外。
当第一泵8与接水站1之间的高度差过大时，在竖井内的吊盘7上设置水箱2，同时增加将水箱2中的水抽取并输送至储水仓4的第三泵3。
井壁的淋水量大时，加设截水装置6，将储水仓4上部的竖井井壁淋水直接引导至储水仓4内。截水装置6使用实施例1中示出的结构。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。
