The invention provides a slurry pipe replacing system and method suitable for slurry shield split starting. The slurry pipe replacement telescopic system comprises a slurry pipe sliding rail arranged on the side wall of a shield launching area, a slurry inlet pipe supporting platform and a slurry return pipe supporting platform, the slurry inlet pipe supporting platform and the slurry return pipe supporting platform are located on the ground, and a slurry inlet pipe and a slurry return pipe each comprise a telescopic hose section, a fixed section connected to the tail end of a shield trolley and a vertical supporting section connected with the telescopic hose section and the fixed section. The telescopic hose section of the slurry inlet pipe is arranged on the slurry inlet pipe supporting platform in a sliding mode, the telescopic hose section of the slurry return pipe is arranged on the slurry return pipe supporting platform in a sliding mode, the slurry pipe sliding rail is parallel to the walking direction of the shield tunneling machine, and the vertical supporting section of the slurry inlet pipe and the vertical supporting section of the slurry return pipe are both connected with the slurry pipe sliding rail in a sliding mode through a sliding mechanism. The whole pipe replacing process is simple and convenient, a matched pipe replacing device is not needed, compared with a traditional pipe replacing device, the construction space is saved, and the pipe replacing device is suitable for being used under the condition that the space is narrow and no pipe replacing device installation space exists.

The utility model relates to a knee -pad technical field, concretely relates to a gasbag type knee -pad, the utility model discloses through setting up the gas compression mechanism, including annular fixing piece, the inside of annular fixing piece is equipped with annular gasbag, the gasbag type knee -pad still includes gas compression mechanism and trachea, the gas compression mechanism is used for controlling the air pressure in annular gasbag, the gas compression mechanism is communicated with annular gasbag through trachea. The gas compression mechanism is communicated with annular gasbag through trachea, so that annular gasbag constantly carries out inflation and deflation, can pass through the repeated inflation and deflation process of annular gasbag, makes the annular gasbag inflation and locks the leg when the leg joint is stressed, the annular gasbag deflates and makes the leg relax when the leg is lifted, so that the leg blood can normally circulate and can promote blood circulation, avoids the leg tumefaction and is not comfortable.
