Abstract

The invention discloses a continuous excavation device and a full-face heading machine. The continuous excavation device comprises a rear main beam (3) and a sliding box (4) which are sleeved inside and outside, the rear main beam (3) extends in a front-back direction, the sliding box (4) can move in the front-back direction, excavation mechanisms are arranged on the left side and the right side of the sliding box (4), each excavation mechanism comprises supporting arms (6) and wheel type cutter heads (7), and the supporting arms (6) and the wheel type cutter heads (7) are arranged up and down. A wheel type cutter head (7) is connected with a supporting arm (6) through a cutter head shaft (16), and the axis of the cutter head shaft (16) is arranged in a left-right direction. According to the continuous excavation device, the continuous excavation device can be conveniently carried on an existing circular shield tunneling machine or a TBM shield tunneling machine, one-time excavation forming of the section of a special-shaped tunnel (similar to a city gate opening shape or a horseshoe shape) is achieved, the quality of the formed section is good, and the continuous excavation device has the advantages of being safe, stable, high in efficiency, capable of integrating excavation and supporting and the like.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to a continuous excavation device and a full-face tunneling machine. Background technique [0002] At present, the common tunnel excavation section is a circular section, which has the advantages of good force bearing and high tunnel safety; however, a certain amount of backfilling work is required on the bottom of the circular section tunnel when laying track or road surface. This restricts the use of the lower space of the circular tunnel, reducing the space utilization rate of the tunnel section; and for tunnels that require passing traffic, it is necessary to specially reserve a crossing chamber or expand the excavation diameter of the section, which increases the size and weight of the tunnel excavation equipment , Increased the excavation volume of the tunnel at the same time, and then increased the construction cost of the tunnel. [0003] In order to solve the a...
