盾构联络通道掘进设备

本发明提出了盾构联络通道掘进设备，涉及盾构施工领域，尤其涉及盾构联络通道掘进设备，本发明通过驱动装置带动整个钢管环做回转运动，带刀具的钢管环对土体进行切削，并有推进油缸提供推进力使得整个管环向前掘进。在密封装置上安装有泥浆管，连接泥浆泵，由泥浆泵将泥浆或其他土壤改良剂泵入钢管环内部，对内部的渣土进行冲刷，由于密封装置与掘进表面呈一个压力仓，当钢管环内压力过大时，钢管环内部的泥浆进入钢管环与掘进所形成的隧道壁之间的缝隙，再打开始发筒上的球阀，泥浆通过球阀上安装的管道进入泥浆处理池。通过本发明进行联络通道的挖掘大大的缩短了工期，并且避免了现有技术中通过人工挖掘的安全隐患。 The present invention provides a shield contact channel excavating device, relates to the field of shield construction, and especially relates to a shield contact channel excavating device. The wholesteel pipe ring is driven by a driving device to perform rotational motion, the soil is cut by the steel pipe ring with cutters, and a propulsion oil cylinder is disposed to provide propulsive force to enable the whole pipe ring to excavate forward. A sealing device is equipped with a slurry pipe, the slurry pipe is connected with a slurry pump, and slurry or other soil conditioner is pumped intothe steel pipe ring by the slurry pump to wash muck in the steel pipe ring. Due to the fact that a pressure compartment is formed between
