Reusable landfill collection drilling pile
The invention discloses a reusable landfill collection drilling pile. The reusable landfill collection drilling pile comprises a pipe body, the pipe body comprises sub pipe bodies which sequentially communicate with each other from top to bottom, wherein a drill bit is connected to the bottom of the lowest sub pipe body, a flange disc is fixed to the periphery of the top of the lowest sub pipe body, and flange discs are correspondingly connected to the tops and bottoms of the other sub pipe bodies; the sub pipe bodies comprise outer pipes, and inner liner pipes are rotatably connected into theouter pipes; a plurality of liquid absorption holes are formed in the outer pipes, and communicating holes are formed in the inner liner pipes corresponding to the liquid absorption holes; and the inner liner pipes rotate to communicate the communicating holes with the liquid absorption holes or to completely stagger the communicating holes with the liquid absorption holes. According to the reusable landfill collection drilling pile, when extending into a garbage layer, the garbage layer can be locally stirred, and the aerobic reaction of garbage is accelerated; gas and liquid are quickly absorbed, the installation and recovery of a pipe pile can be achieved by connecting a drilling machine, and waste is avoided; and a collection hole can be closed or opened according to the needs, the pipe body can be disassembled and lengthened, and the depth can be designed and adjusted according to the actual situation of a landfill site.
本发明公开了一种可重复利用填埋场收集钻桩，包括管体，所述管体包括由下到上依次连通的子管体，其中，最下方的子管体底部连接有钻头，顶部外周固定有法兰盘，其余的子管体顶部和底部均连接有法兰盘；所述子管体包括外管，外管内旋转连接有内衬管；外管上成形有若干吸液孔，内衬管上对应吸液孔成形有连通孔；内衬管通过旋转使得连通孔与吸液孔连通或使得连通孔与吸液孔完全交错开。本发明伸入垃圾层时，能够局部搅动垃圾层，加块垃圾的有氧反应；快速吸收气体和液体,能够在通过连接钻机实现管桩的安装和回收，避免浪费；收集孔可以根据需要进行关闭或打开且管体可以拆卸和加长，可根据垃圾填埋场实际进行设计调整深度。
