因此，以下对附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“左”、“右”、“内”、“外”、“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该发明产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。本发明的实施例的附图中设置有坐标系XYZ，其中X轴的正向代表前方，X轴的反向代表后方，Y轴的正向代表右方，Y轴的反向代表左方，Z轴的正向代表上方，Z轴的反向代表下方。
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
结合图1和图2所示，本发明实施例的一种装配式地铁车站施工方法，其中，装配式地铁车站包括底层组件1、中层组件2和顶层组件3，底层组件1通过中层组件2与顶层组件3相互连接；所述装配式地铁车站施工方法包括：
开挖基坑；
装配底层组件1，当完成预定环数的底层组件1的装配时，开始在底层组件1上进行中层组件2的装配；
当完成预定环数的中层组件2的装配时，开始在中层组件2上进行顶层组件3的装配，此时底层组件1、中层组件2和顶层组件3呈阶梯式设置且同时进行装配。
结合图2所示，具体地，在本实施例中，在基坑开挖完成后，先进行底层组件1的装配，将底层组件1装配至预定的环数后，开始在底层组件1上进行中层组件2的装配，此时底层组件1和中层组件2同时在进行装配。 当中层组件2装配进度达到预定的环数时，开始在中层组件2上进行顶层组件3的装配，待顶层组件3与中层组件2装配完成时便可形成一个完整的环，此时底层组件1、中层组件2和顶层组件3呈阶梯式同时进行装配。应当理解的是，当顶层组件3完成一个预定环数的装配时，此时中层组件2已完成第二个预定环数的装配，底层组件1已完成第三个预定环数的装配，即底层组件1始终比中层组件2多完成一个预定环数，同时中层组件2始终比顶层组件3多完成一个预定环数，由此底层组件1、中层组件2和顶层组件3可以实现同时进行装配，与依次成环或者在所有底层组件1完成装配后，再装配中层组件2，最后装配顶层组件3相比，进一步提高了工作效率。
需要说明的是，底层组件1装配至预定环数后，中层组件2开始装配时，底层组件1并未停止装配，此时底层组件1和中层组件2同时进行装配。由此，在底层组件1的装配第一次达到预定的环数后，中层组件2开始装配，待中层组件2的装配第一次达到预定的环数后，底层组件1已第二次达到预定的环数。当中层组件2的装配第一次达到预定的环数后，顶层组件3开始装配，底层组件1、中层组件2也并未停止装配，之后底层组件1、中层组件2和顶层组件3同时进行装配。由此，在顶层组件3的装配第一次达到预定的环数后，中层组件2已第二次达到预定的环数，底层组件1已第三次达到预定的环数，底层组件1、中层组件2和顶层组件3便可以呈现阶梯式持续同时装配，直至装配完成。
应当理解的是，环数是指底层组件1、中层组件2或顶层组件3沿地铁行驶方向上排列的个数。
需要说明的是，在本实施例中，也可在所有底层组件1装配完成后，在底层组件1上进行中层组件2的装配，等所有中层组件2装配完成后，最后在中层组件2上装配顶层组件3。
结合图2和图3所示，优选地，底层组件1包括底部构件11和两个底角构件12，两个底角构件12分别设置在底部构件11的两端，在装配底层组件1时，其中第一环底层组件1通过龙门吊进行装配，通过龙门吊将底部构件11固定在基坑底面，之后将两个底角构件12分别固定在底部构件11的两端，以完成第一环底层组件1的装配。
由此，在进行底层组件1装配时，第一环通过龙门吊装配，保证了一开始装配时的精度。
优选地，底层组件1的装配还包括：利用底层拼装机4装配其余环底层组件1，并利用所述底层拼装机4对每一环进行纵向压紧，保证底层组件1底部的稳固性。
应当理解的是，纵向压紧是指向垂直于地面方向压紧，通过底层拼装机4对每一环向垂直于地面方向进行压紧，保证了装配后的稳定性。
在本实施例中，利用底层拼装机4装配其余环底层组件1包括：利用底层拼装机4将底部构件11固定在基坑底面，并将两个底角构件12分别固定在底部构件11的两端。
结合图3所示，具体地，底层组件1包括底部构件11和两个底角构件12，底层拼装机4需要将底部构件11固定在基坑的底面，接着将两个底角构件12安装至底部构件11的两端，以此完成一环底层组件1的装配，重复将底部构件11与两个底角构件12进行装配，直至完成所有底层组件1的装配。
在本实施例中，该地铁车站施工方法还包括：每完成一个预定环数的所述底层组件1的装配时，对所述底层组件1的肥槽进行回填，每完成一个预定环数的所述中层组件2的装配时，对所述中层组件2的肥槽进行回填，每完成一个预定环数的所述顶层组件3的装配时，对所述顶层组件3的肥槽进行回填。
在一个具体实施方式中，当底层组件1完成第一个预定环数后，对第一个预定环数内的底层组件1的肥槽进行回填。当底层组件1完成第二个预定环数后，此时中层组件2完成第一个预定环数，对第二个预定环数内的底层组件1以及第一个预定环数内的中层组件2的肥槽进行回填。当底层组件1完成第三个预定环数后，此时中层组件2完成第二个预定环数，以及顶层组件3完成第一个预定环数，对第三个预定环数内的底层组件1、第二个预定环数内的中层组件2以及第一个预定环数内的顶层组件3的肥槽进行回填，保证施工过程中的结构强度。以此类推，直至对底层组件1、中层组件2以及顶层组件3的所有肥槽进行回填。
结合图2和图3所示，在本实施例中，中层组件2包括中板构件21和两个侧板构件22，两个侧板构件22的底端分别与两个底角构件12的顶端固定连接，中板构件21的两端分别与两个侧板构件22固定连接；底层组件1装配至预定环数后，此时开始利用中层拼装机5将两个侧板构件22分别固定在底层组件1的两个底角构件12上，将中板构件21固定在两个侧板构件22之间，以此完成在底层组件1上装配中层组件2。
结合图3所示，优选地，顶层组件3包括两个顶角构件32和顶板构件31，两个顶角构件32的一端分别与两个侧板构件22的顶端固定连接，顶板构件31的两端分别与两个侧板构件22的另一端固定连接，当中层组件2装配至预定环数后，此时开始利用顶层拼装机6将两个顶角构件32分别固定在中层组件2的两个侧板构件22的顶端，同时将顶板构件31固定在两个顶角构件32之间，以此完成中层组件2与顶层组件3之间的装配。
作为一个优选地实施方式，在底层组件1、中层组件2和顶层组件3装配之前铺设轨道，通过在各个所述轨道上设置对应的拼装机分别对所述底层组件1、所述中层组件2和所述顶层组件3进行装配。
具体地，在通过龙门吊完成第一环底层组件1的装配后，先在基坑底部铺设基层轨道，之后利用龙门吊将底层拼装机4放置在基层轨道上，通过底层拼装机4在基层轨道上移动，实现对多环底层组件1的持续装配。
需要说明的是，基层轨道一开始就已在基坑底部全部铺设完成，龙门吊将底层拼装机4放置在基层轨道上就可以持续对底层组件1进行装配，底层轨道和中层轨道随着组件完成预定环数的次数而相应增加铺设。
结合图2所示，具体地，当底层组件1装配至预定环数后，开始在第一次完成预定环数内的底层组件1上铺设底层轨道，通过龙门吊将中层拼装机5放置在底层轨道上，通过中层拼装机5在底层轨道上移动，从而在已完成第一次预定环数的底层组件1上进行相应的第一次预定环数的中层组件2的装配，此时底层拼装机4和中层拼装机5同时工作，当中层组件2完成第一次预定环数的装配后，此时的底层组件1已经完成第二次预定环数的装配。
当中层组件2完成第一次预定环数的装配，底层组件1完成第二次预定环数的装配后，在完成第一次预定环数的中层组件2上进行第一段中层轨道 的铺设，同时在完成第二次预定环数的底层组件1上进行第二段底层轨道的铺设，第一段中层轨道和第二段底层轨道铺设完成后，通过龙门吊将顶层拼装机6放置在第一段中层轨道上，此时同时开启底层拼装机4、中层拼装机5和顶层拼装机6，分别对底层组件1、中层组件2和顶层组件3下一个预定环数进行装配。应当理解的是，此时的下一个预定环数的装配是指，底层组件1完成第三个预定环数的装配、中层组件2完成第二个预定环数的装配以及顶层组件3完成第一个预定环数的装配。当再次进行下一个预定环数的装配时，需要再次在第三个预定环数的底层组件1上铺设第三段的底层轨道和在第二个预定环数的中层组件2上铺设第二段的中层轨道，之后再次同时启动底层拼装机4、中层拼装机5和顶层拼装机6同时进行装配，从而呈阶梯式完成底层组件1的第四个预定环数、中层组件2第三个预定环数以及顶层组件3第二个预定环数的装配。以此类推，完成全部底层组件1、中层组件2和顶层组件3的装配。
下面通过一个具体的实施例对本发明进行详细说明。
示例性地，装配式地铁车站施工方法包括如下步骤：
开挖基坑。
在基层铺设轨道，用龙门吊将底层组件1的第一环进行装配，底角构件12与底部构件11横向固定。应当理解的是，横向是指底角构件12与底部构件11的装配方向。
在基坑底部铺设基层轨道，用龙门吊将底层拼装机4放在基层轨道上。
通过底层拼装机4对底层组件1进行装配并用底层拼装机4对每一环进行纵向压紧，当完成第一个流水段后，对已完成流水段的底层组件1的底层肥槽进行回填。需要说明的是，流水段是指分多段完成时其中一段中所包括的环数，可以根据实际需求选择一个流水段内的环数。
当回填强度达到要求以后，拆除第一流水段底层范围内的第二钢支撑8。
拆除完成后在第一流水段内的底层组件1上铺设底层轨道，用龙门吊将中层拼装机5安装在底层轨道上，对中板构件21及侧板构件22进行装配，以完成底层组件1与中层组件2之间的装配。
此时中层拼装机5与底层拼装机4同时进行装配作业，当中层组件2 完成第一个流水段装配后，此时底层组件1已完成第二个流水段装配，对底层组件1第二流水段内的底层肥槽及中层组件2第一流水段内的中层肥槽进行回填。
当回填强度达到要求以后，拆除底层组件1第二流水段内的第二钢支撑8，同时拆除中层组件2第一流水段内的第一钢支撑7。应当理解的是，第一钢支撑7和第二钢支撑8随着底层组件1和中层组件2依次完成的流水段而相应依次拆除，保证基坑的结构强度，防止坍塌。
拆除钢支撑以后，再次在第二个流水段内的底层组件1铺设底层轨道以及第一个流水段内的中层组件2铺设中层轨道，铺设完成后，用龙门吊将顶层拼装机6安装在中层轨道上，用顶层拼装机6对顶板构件31和顶角构件32进行装配，以在第一个流水段内中层组件2上进行顶层组件3的装配。
此时底层拼装机4、中层拼装机5和顶层拼装机6分别呈阶梯式同时进行装配，即当顶层组件3完成第一个流水段装配时，中层组件2已完成第二个流水段的装配，底层组件1已完成第三个流水段的装配。
重复上述步骤，直至整个地铁车站完成装配。
