In view of the problems occurred in throwing of the tetrahedron-like penetrating frame,such as low efficiency,high cost,poor accuracy and potential safety hazard,we establish theoretical model of the drift distance for the tetrahedron-like penetrating frame during throwing,and obtain the influences of the throwing height,the depth of water,the flow rate,the blocking water area of the tetrahedron-like penetrating frame on the drift distance.We propose an automatic synchronous throwing lifting gear with a large frame and multiple-rotors,increase the number of the permeable tetrahedron frames,anchor the throwing ship precisely by GPS,and monitor the throwing action timely.The results show that the throwing equipment can enhance the throwing precision of the penetrating frame and increase the efficiency of construction.
