Abstract

The invention discloses a sinking type vertical shaft heading machine. The sinking type vertical shaft heading machine comprises a main machine, a sinking system, a pipeline system and a main machinerecycling system. The sinking system, the pipeline system and the main machine recycling system are correspondingly installed on a wellhead ring beam. The main machine is arranged in a vertical shaft;a vertical shaft blade foot and a basic pipe joint which are connected are arranged on the inner side of the vertical shaft; the sinking system is connected with the vertical shaft blade foot; the main machine recycling system is connected with the main machine; the main machine comprises a milling and digging head, a supporting arm, a rotary unit, a connecting cross beam and a deslagging pump unit, one end of the supporting arm is hinged to the rotary unit, and the other end of the supporting arm is connected with the milling and digging head; one side of the connecting cross beam is connected with one side of the rotary unit, and the other side of the connecting cross beam is connected with the basic pipe joint; and the deslagging pump unit is installed on the milling and digging head.The sinking type vertical shaft heading machine has the advantages of being high in excavation speed, high in safety, small in construction site, high in well completion precision, wide in geologicaladaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery for shaft construction, and in particular relates to a submerged shaft boring machine and a well-forming method. Background technique [0002] The development of the city has brought a series of problems such as traffic congestion, environmental pollution, urban land shortage and severe energy shortage. In order to maintain normal life, or for other needs such as combat readiness, people are constantly seeking to develop new spaces. Today, the field of human activities has developed into a three-dimensional space. In addition to the ground and water space, it has also begun to enter the vast underground space. Shaft construction has been widely used under this demand. For example, starting and receiving shafts of underground tunnel boring machines, tunnel ventilation shafts, urban drainage system shafts, underground three-dimensional garages and storage shafts, mining shafts, bridg...
