The invention discloses a horizontal planing machine for machining internal hole spline grooves of long shaft parts. The horizontal planing machine comprises a horizontal planing machine body (11) and is characterized in that the horizontal planing machine body (11) is provided with a tool, a first clamp and a second clamp. According to the horizontal planing machine, the clamps and the tool are improved on the basis of a common horizontal planing machine body, and therefore the internal hole spline grooves of the long shaft parts can be machined efficiently, easily and conveniently, the functions of the horizontal planing machine can be expanded, and the machining cost can be lowered.

The invention discloses a construction method for an extension model of a slurry splitting fissure in a clay stratum. The construction method comprises the steps that 1, the clay stratum is formed; 2,a steel pipe is embedded into the clay stratum, a slurry pressurizing pipe is connected to the bottom end of the steel pipe, and pressurizing holes are formed in the peripheral surface of the slurrypressurizing pipe; 3, a pressurizing device is started to form slurry splitting; and 4, it is assumed that the fissure extends in a circular plate-shaped space, the perimeter of the circular plate-shaped space and the time for reaching the perimeter are calculated, or it is assumed that the slurry splitting fissure extends in a semielliptical plate-shaped space and the semiellipse is simplified into a trapezoid, the extension speed of the semi-minor axis of the semielliptical plate-shaped space, the long axis length of the semiellipse and the time for reaching the long axis length are calculated. According to the construction method, parameters such as the extension speed and the total extension amount of the splitting fissure can be calculated through the constructed model, quantization of related parameters in the slurry splitting process is achieved, and reference is provided for studying the slurry splitting extension mechanism.
