| description | The invention provides a construction method for disassembling a shield body of a shield tunneling machine in a hole in a non-expanding-excavation blocking mode. The construction method comprises the steps that firstly, oil cylinder partition plates of an upper block of a front shield and an upper block of a middle shield are cut off; secondly, the upper blocks of the middle shield are dismantled; thirdly, the middle shield left sub-block and the middle shield right sub-block are dismantled; fourthly, the front shield upper blocks are dismantled; fifthly, the front shield left sub-block and the front shield right sub-block are dismantled; and sixthly, the middle shield lower sub-block and the front shield lower sub-block are dismantled. According to the construction method for disassembling the shield body of the shield tunneling machine in the hole in the non-expanding-excavation blocking mode, the organization is clear, the efficiency is high, the time is saved, the disassembling procedure is simplified by |
