Description

Soil discharging and transferring system for rotary digging construction in narrow space Technical Field The utility model belongs to the technical field of underground working well construction, and particularly relates to a soil discharging and transporting system for narrow space rotary excavation construction. Background When the subway line is constructed, a working well needs to be excavated on the ground by a drilling machine. The working well is conveniently excavated in the open area, but in the area with a space constraint, construction equipment is limited by original attachments on the ground, and normal construction cannot be performed. For example, large cities such as Beijing, shanghai, etc., still exist in a large number of old urban areas, and some work wells are required to be constructed in narrow streets less than 5m wide according to survey requirements. The width of the drilling machine is about 4m, so that the drilling machine can not rotate the machine body to transfer soil lifted by the drilling machine to other places, and the normal development of engineering is severely restricted. Disclosure of utility model The utility model aims to provide a soil discharging and transporting system for rotary excavation construction in a narrow space, which can transfer soil by means of a transporting trolley which shuttles below an excavator, and ensure normal operation of construction tasks. In order to achieve the above purpose, the utility model provides a soil discharging and transporting system for rotary digging construction in a narrow space, which comprises the following technical scheme: A first rail arranged at one side of the rotary digging point in the construction area; The track opening and closing device is provided with two second tracks, a space for vertical lifting operation of the rotary drilling bit is formed after the track opening and closing device is in an open state, and the second tracks are aligned with the first tracks one by one after the track opening and closing device is in a closed state; And the transfer trolley moves back and forth on the first track and the second track.
