Development of KCM130 Steerable Air-Powered Impact Mole for Directional Boring
New Pipeline Technologies, Security, and Safety(2003)
摘要
In this paper the working principle of a steerable air-powered impact mole is described in detail. Determination by model experiments of the cone-apex angle and the maximum deflection angle of the chisel head of the impact mole is introduced. The steerable air-powered impact mole consists of an adjusting system of chisel head and . an air hammer system. Both systems are described in detail. The field test of the prototype machine is introduced. The result of the preliminary field test proves that KCM130 steerable air-powered impact mole can be used for directional boring with the help of a radio detective system.
