Abstract

The invention discloses a milling wheel for underground continuous wall excavation and a two-wheel slot milling machine. In a main milling tooth region, milling teeth are evenly arranged in the axis direction of a roller, and the tooth tip circle radius of the milling teeth are periodically fluctuated in the axis direction of the roller, so that the bottom of corresponding milling groove forms anuneven milling section with periodic fluctuations; and in the circumferential direction of the roller, a plurality of milling teeth are cut into a rock in a skipped mode, so that all the milling teethare located in the axial direction, the diameter direction and the circumferential direction, so that all the milling teeth create milling free surfaces in the three dimensions mutually, each millingtooth can conduct unilateral crushing or bilateral crushing when milling a rock formation, cracks are easily crossed mutually, the milling resistance of each milling tooth is reduced, thus, the rockbreaking ability of the milling wheel is improved, the losses of the milling teeth are reduced, and the construction efficiency of the two-wheel slot milling machine is improved.

Description

technical field [0001] The invention belongs to the technical field of underground diaphragm wall excavation, and relates to a milling wheel and a double-wheel groove milling machine used for excavating an underground diaphragm wall. Background technique [0002] Double-wheel slot milling machine is the core equipment for the construction of underground diaphragm wall, which has the characteristics of large slot depth, high verticality and strong stratum adaptability. The milling wheel is responsible for the milling and crushing of rock and soil strata. It is the core working device of the double-wheel slot milling machine and plays a key role in the construction efficiency of the whole machine. [0003] However, during the excavation of strata above medium-hard rock, it is difficult to break the rock, and there are problems such as low construction efficiency and large wear of the milling teeth. It affects the construction progress of the underground diaphragm wall project...
