Description

多个相邻超深竖井施工过程中共用的排水系统及多个相邻超深竖井施工时的共同排水方法 技术领域
本发明涉及竖井施工技术领域，具体涉及多个相邻超深竖井施工过程中共用的排水系统及多个相邻超深竖井施工时的共同排水方法。
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。
超深竖井在施工过程中，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以下的超深竖井施工时，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。
超深竖井施工受井下作业空间狭小限制，超过1200m的超深竖井超深采用排水泵难以直接将井底工作面的涌水排至地面。相邻的多个超深竖井(比如主井、副井和风井)在实际施工的过程中，排水时需要安装各自独立的排水系统，排水机电设备和材料投入增加巨大，需增加排水系统的维护人员及费用。
发明内容
针对现有技术中存在的问题，本发明提供多个相邻超深竖井施工过程中共用的排水系统及多个相邻超深竖井施工时的共同排水方法。
本专利首先提供一种多个相邻超深竖井施工过程中共用的排水系统，包括多个第一泵，所述第一泵用于分别将超深竖井工作面的水抽出；
在其中一个超深竖井的壁上设置有接水站，接水站内设置有用于存储从多个相邻的竖井工作面抽出的水的储水仓，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，未设置接水站的超深竖井的井壁上设置有沉淀仓，沉淀仓用于接收该竖井内的第一泵抽取的该竖井工作面的水并对水中的泥沙进行沉淀；沉淀仓与储水仓之间设置有连通水管，连通水管用于将沉淀仓内的沉淀后的水输送至储水仓内。
在上述方案的基础上，所述连通水管的进水口高度高于沉淀仓的底面1.5-1.8m；所述连通水管的进水口处设置有过滤网。
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；所述沉淀仓还用于接收沉淀仓以上的竖井井壁淋水。
在上述方案的基础上，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或沉淀仓的输水管。
在上述方案的基础上，所述截水槽由若干个截水槽模块插接而成；所述截水槽模块为U形，其中一个侧壁用于将截水槽模块固定在竖井井壁上；截水槽模块的一端为接收端，另一端为插入端；一个截水槽模块的接收端用于与它相连接的一个截水槽模块的插入端插入，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的接收端。
在上述方案的基础上，所述截水槽模块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。
在上述方案的基础上，所述截水槽模块的接收端的内壁设置2条并行的内凹的密封槽，截水槽模块的插入端的外壁上设置1条凸起的密封凸；两个截水槽模块插接在一起时，一个截水槽模块的密封凸位于另一个截水槽模块的2个密封槽之间。
在上述方案的基础上，所述截水槽模块靠近竖井井壁侧的侧壁外部设置有弹性板。
在上述方案的基础上，所述截水槽模块为注塑一体成型。
本专利还提供一种多个相邻超深竖井施工时的共同排水方法，在每个竖井内均安装用于将超深竖井工作面的水抽出的第一泵；
在其中的一个竖井的井壁上设置接水站，接水站内设置储水仓和用于将储水仓内的水抽取并输送至竖井外的第二泵；该竖井内的第一泵抽出的水被输送至储水仓内；
在未设置接水站的超深竖井的井壁上分别设置沉淀仓；沉淀仓用于接收该竖井内的第一泵抽取的工作面的水并对水中的泥沙进行沉淀；
在未设置接水站的超深竖井与设置接水站的超深竖井之间设置连通水管；连通水管用于将沉淀仓内的水输送至储水仓内。
在上述方案的基础上，在每个竖井内设置截水装置；在设置接水站的超深竖井内，截 水装置用于接收接水站以上的竖井井壁淋水并将淋水输送至储水仓内；在设置沉淀仓的超深竖井内，截水装置用于接收沉淀仓以上的竖井井壁淋水并将淋水输送至沉淀仓内。
本发明的排水系统可以实现多个相邻超深竖井施工过程中共用一个中间接水站，减少了相邻的其它竖井排水时设置中间接水站排水设备的投入和接水站硐室挖掘的工程量，缩短了矿井建设工期；本发明的排水系统减少了中间接水站排水系统的维护人员及费用，减少了多套接水站设备投入及人员投入。仅使用一个接水站，取消其他竖井内的转水站，因此，简化了井筒布置，增加了安全可靠性。
沉淀仓内的水经自流进入接水站的储水仓，利于污水沉淀，可改善第二泵的工况，减低第二泵维修量和故障率。多个竖井共用一个接水站，有利于集中管理，使排水系统得到合理利用，发挥其最大效能。

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、图2和图3所示，多个相邻超深竖井施工过程中共用的排水系统，包括多个第一泵8，所述第一泵8用于分别将超深竖井工作面(即：竖井的井底)的水抽出；
在其中一个超深竖井的壁上设置有接水站1，接水站1内设置有用于存储从多个相邻的 竖井工作面抽出的水的储水仓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。
以三个竖井共用一个接水站为例，图1中的三个竖井中分别设置第一泵8，第一泵8分别将各自对应的超深竖井工作面的水抽出，最终将水送入储水仓4内。
将未设置接水站的竖井内的水输送至储水仓4内的具体方法是：
未设置接水站1的超深竖井的井壁上挖掘并设置有沉淀仓9，沉淀仓9用于接收该竖井内的第一泵8抽取的该竖井工作面的水并对水中的泥沙进行沉淀；沉淀仓9与储水仓4之间设置有连通水管10，连通水管10用于将沉淀仓9内的沉淀后的水输送至储水仓4内。
使用本专利的排水系统时，多个相邻的超深竖井距离不宜太远，一般在100m以内，否则，两井之间设置连通水管10的难度太大，贯通误差太大。接水站最好设置在井筒断面大的竖井中，便于布置排水管路，保证提升运输安全。
图3中的三个超深竖井可以分别时主井、副井和风井，其中因为副井的断面较大，因此在副井中设置接水站1，在主井和风井内设置沉淀仓9。
先在选好的竖井中的井壁上挖掘并设置接水站1，之后从设置接水站的硐室迎面向相邻的竖井钻孔，按接水站的底板面以上1.5-2.0m定钻孔标高，按坡度10-14‰的上坡定钻孔走向；这样既能保证钻孔贯通，又能使钻孔的出口位置高，便于后期水流入储水仓4；钻孔完成后，设置好连通水管10。如图2所示，连通水管10的进水口高度高于沉淀仓9的底板面1.5-1.8m；所述连通水管10的进水口处设置有过滤网(图中不再示出)。这样，沉淀仓9有一定的蓄水量，能沉淀部分泥沙，避免堵塞连通水管10，同时可以避免过大的泥沙造成储水仓4的清淤压力。
随着竖井的深度不断加大，当第一泵8与接水站1或沉淀仓9之间的高度差过大时，如图3所示，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)，无需再增设新的接水站。
在未设置接水站1的超深竖井内也使用图3中的装置，比如水箱2、第三泵3，这样可以同样减少对排水设备性能的要求。
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或沉淀仓9的上部(即：高度高于接水站1或高于沉淀仓9)的竖井井壁淋水直接引导至储水仓4或沉淀仓9内，具体可以使用截水装置6，截水装置6可以将接水站1或沉淀仓9以上的竖井井壁淋水汇集并引导至储水仓4或沉淀仓9内。
如图3和4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或沉淀仓9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或沉淀仓9。设置截水槽6-1时，远离出水口6-2的一侧高于出水口6-2一侧，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4、图5、图6和图7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5的左侧端)，另一端为插入端(如图5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7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7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5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。
