Driving device applied to pipe jacking method, and construction method for same

Abstract

The invention discloses a driving device applied to a pipe jacking method. The device comprises an excavation device, a head front end track, a middle track and a rear device, wherein the excavation device is composed of a transmission device and a chain cutter, and the transmission device is composed of a drive device and a chain wheel; the chain cutter used to excavate rocks and soil runs on the head front end track and the middle track during construction, and the shape of a head excavation face is the same with the shape of a tubular joint cross section; the rear device comprises a jacking device which is installed in a construction shaft; the front end of the middle track is connected to the head front end track; the tail end of the middle track is connected to the rear device; and during construction, the chain cutter is drive by the drive device to run along the tracks, and annular rocks and soil in a projection part of the tubular joint cross section are excavated by a cutter on the head front end track. The device and method have the advantages that an operation platform is established in the working shaft, and surround environments are only influenced slightly; the head part of a first tubular joint is an excavation face of the excavation device; excavated rocks and soil are brought by the chain cutter to the working shaft; the rocks and soil in the tubular joint are removed after in-situ jacking of the tubular joint; construction is simple; quality is high; construction duration is short; and cost is low.

Description

technical field [0001] The invention relates to a tunneling device for pipe jacking and a construction method thereof, and belongs to the technical field of civil engineering foundation construction. Background technique [0002] Existing tunnel construction includes construction after open excavation, and underground excavation construction for pipe jacking or shield tunneling; open excavation construction has a large amount of excavated earthwork, long construction period, and high cost; existing underground excavation construction costs are relatively expensive. [0003] Existing subway stations adopt the open-cut method. The traditional open-cut method has a relatively large impact on the surrounding environment. It is difficult to support the slope, and the amount of earth excavation is large. It is only suitable for open ground and good geological conditions. The construction period is long, Expensive.
