Soil pressure balance muddy water conveying type planetary single-cutter-disc square pipe jacking machine and construction method thereof

Abstract

The invention discloses a soil pressure balance muddy water conveying type planetary single-cutter-disc square pipe jacking machine and a construction method thereof. According to the soil pressure balance muddy water conveying type planetary single-cutter-disc square pipe jacking machine and the construction method thereof, the pipe jacking machine comprises a spoke type single cutter disc and a soil bin arranged at the front end of the pipe jacking machine, the back face of each spoke of the single cutter disc is fixedly provided with a first stirring rod, and the first stirring rods are located at the positions deviating from the autorotation center of the single cutter disc. The soil bin is connected with a water supply pipeline, the water supply pipeline is provided with a water pump for controlling water supply, a back plate on one side, far away from the single cutter disc, of the soil bin is provided with a first rotating disc, the first rotating disc and the back plate of the soil bin are sealed through a sealing structure, the single cutter disc is connected with the first rotating disc and a planetary driving device, and a plurality of second stirring rods are fixed on the first rotating disc. The technical problem that in the prior art, in the pipe roofing construction process, mud-water balance during mud-water conveying out-of-soil is not easy to control is solved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to an earth pressure balance mud-water conveying type planetary single-cutter square pipe jacking machine and a construction method thereof. Background technique [0002] The pipe curtain construction method, also known as the pipe jacking method, is a construction technology that uses a small-diameter pipe jacking machine to construct a large-section underground space, and is a new type of underground excavation technology. At present, in most pipe jacking construction projects of pipe curtains, the pipe curtain structure mostly adopts circular steel pipe structure. The circular steel pipes in this pipe curtain structure cannot cooperate with each other and only bear force in one direction, so the support efficiency is poor. The unearthed form of the pipe jacking machine in the pipe curtain construction of the prior art is the excavation by the screw machine or the mud and water ...
