Thick mud type rock pipe-jacking machine with replaceable cutter head for cobble stratum

Abstract

The invention discloses a thick mud type rock pipe-jacking machine with a replaceable cutter head for cobble stratum. The thick mud type rock pipe-jacking machine comprises a hob cutter head, a powersystem, a front cylinder and a mud removing system, wherein a connecting cylinder is fixed at the front end of the front cylinder in a sleeving manner; a rear cylinder is fixed at the rear end of thefront cylinder; the front cylinder is connected with the rear cylinder by virtue of a corrective cylinder; the power system is fixedly mounted in the front cylinder; working power is provided for eachcomponent of the pipe-jacking machine by the power system; and the power system comprises a motor and a reducer connected with the motor. The thick mud type rock pipe-jacking machine disclosed by theinvention has the beneficial effects that the pipe-jacking machine disclosed by the invention is capable of adapting to the cobble stratum and also adapting to slush soft soil stratum, and the tunneling efficiency is ensured. The installation and detachment can be simple and convenient, the safety is ensured, and the cost is saved. According to the pipe-jacking machine disclosed by the invention,the tunneling efficiency of the cobble stratum is ensured, the tunneling of various stratum is realized by replacing the cutter head, and the benefits are maximized. The untwisting structure has excellent social benefits and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a pipe jacking machine, in particular to a thick mud rock pipe jacking machine with a replaceable cutter head in a pebble formation, and belongs to the technical field of pipe jacking applications. Background technique [0002] With the development of the country's underground pipeline network, the demand for pipe jacking machines is increasing. my country has a vast territory and complex engineering geology and hydrogeology conditions. Pipe jacking is used in various strata, such as soft soil, silt, sand, pebbles, rocks, etc. Due to the complex geological conditions, each project should select the appropriate pipe jacking equipment according to the hydrological and geological conditions of the project. The pebble formation is relatively difficult to deal with, and it is particularly important for a pipe jacking machine to adapt to the pebble geological conditions as much as possible. [0003] At present, the pipe jacking mac...

AI Technical Summary

Problems solved by technology

Either it is an ordinary mud water cutter head, the pebbles cannot enter the warehouse, and the cutter head is blocked in severe cases, and the pipe jacking machine cannot be jacked; or it is a rock pipe jacking machine, the secondary crushing power is large and the jacking speed is slow, and the secondary crushing of pebbles is difficult. When the progress is slow and projects with different geology are encountered, the construction cost will be greatly increased, and a thick mud rock pipe jacking machine with replaceable cutterheads in pebble formations is proposed.
