The utility model discloses a reinforced shield machine cutterhead of tunnelling contour line peripheral stratum, this shield machine cutterhead includes cutterhead, high pressure nozzle, grouting pipe and grouting pump, and the cutterhead includes ring beam, amplitude arm and flange plate, and the amplitude arm is fixed evenly on the flange plate with interval, and the middle part and the end of amplitude arm are connected through ring beam, and the cutter is installed on the cutterhead, and the outer edge surface of the outermost ring beam is provided with mounting hole, and the high pressure nozzle is installed in the mounting hole, and the grouting pump is installed on the shield machine trolley. The utility model improves the structure on the cutterhead, and the mounting hole is arranged on it, and the high pressure nozzle is installed in the mounting hole, and the high pressure cement slurry is injected into the nozzle through the grouting pump through the grouting pipe, and the high pressure cement slurry that sprays cuts and stirs the stratum outside tunnelling contour and mixes with the soil, forms the mixture of cement and soil, and the mixture forms the cement soil with certain intensity after several days, plays the supporting and water -resisting effect when excavating the butt joint section, prevents stratum collapse and muddy water from gushing into the tunnel.

Adjustable batch rectangular steel plate feeding assembly and feeding method relate to the technical field of automatic steel plate feeding. The adjustable batch rectangular steel plate feeding assembly comprises a steel plate storage device, a horizontal push plate device and a small plate supporting device. The upper end of the steel plate storage device is provided with a storage interval, the bottom of the storage interval is provided with a height-adjustable steel plate bearing surface, and the top of the storage interval is provided with a steel plate discharge surface. The horizontal push plate device is used for pushing the steel plate at the upper end of the steel plate discharge surface to the outside of the rear end of the steel plate storage device. The upper end of the small plate supporting device is provided with a height-adjustable steel plate transfer surface. When the steel plate transfer surface is at the high position, the steel plate transfer surface is flush with the steel plate discharge surface. When the steel plate transfer surface is at the low position, the steel plate transfer surface is located at the lower end of the storage interval. A continuous rectangular steel plate feeding method is based on the adjustable batch rectangular steel plate feeding assembly. The application is used for stacking and storing steel plates and automatically discharging the steel plates, and belongs to an important link in the automatic manufacturing of nuclear power embedded parts.
