Embodiment Construction
[0019] A tunnel boring machine includes a frame, which is divided into a front section, an excavation section in a cavity and a tail section. The frame excavation device only excavates the ring-shaped rock and soil in the projected area of the frame, and sends the excavated ring-shaped rock and soil at the head to the rear through the rock and soil conveying device in the front section. The front section of the frame and the excavation section in the cavity are open at the head Horizontal cylindrical shape, a certain length of unexcavated rock and soil in the front frame constitutes the waterproof soil sealing section of the roadheader; the excavation section in the cavity only excavates the rock and soil in the cavity, and the tunnel construction is carried out in the tail section.
[0020] The frame excavating device is a chain excavating device, the chain excavating device is composed of a transmission device and a chain cutter, the transmission device is composed of a dri...

Disclosed are a tunnel excavator and a construction method for same. The tunnel excavator comprises a frame. The frame is divided into a front segment (1), an intra-cavity excavating segment (2) and a tail segment (3), the profile of the frame and the profile of a tunnel are the same, the front segment (1) is composed of a frame excavating apparatus (1-1) and a soil sealing segment (1-2), the frame excavating apparatus (1-1) mounted in a head part of a front segment frame (1-3) only excavates rock and soil in a ring shape in a projection area of the excavating frame, rock and soil excavated in a ring shape by the head part is conveyed behind by means of a rock and soil conveying apparatus in the front segment frame, the front segment (1) and the inter-cavity excavating segment (2) of the frame are of a horizontal tube shape with an open head part, and non-excavated rock and soil at a certain length inside the front segment frame (1-3) constitutes the waterproof soil sealing segment (1-2) of the excavator. The inter-cavity excavating segment (2) only excavates rock and soil inside a cavity, and the tail segment performs tunnel construction. Rock and earth are excavated at a rear position of a cavity of the excavator, construction is safe, the manufacturing process for the tunnel excavator is simple, the profile excavated by the excavator is the profile of a tunnel, construction quality is good, the period is short, and costs are low.
Description
technical field [0001] The invention relates to a tunnel boring machine and a construction method thereof, belonging to the technical field of civil engineering foundation construction. Background technique [0002] The manufacturing process of the existing tunnel boring machine is complex, and the technology has high added value. Only a few enterprises in the world have the ability to produce it, and the cost is high. Contents of the invention [0003] What the present invention proposes is a kind of tunnel boring machine and construction method thereof, and its purpose aims at overcoming the defect that prior art exists, and its main advantage: the manufacturing process of tunnel boring machine is simple, and the profile that tunnel boring machine excavates is the profile of tunnel, in The rock and soil are excavated at the rear of the cavity of the roadheader, with safe construction, good quality, short construction period and low cost. [0004] The technical solution ...
