Construction method integrating pilot rope river-crossing and traction system

The invention discloses a construction method integrating pilot rope river-crossing and traction system by building bridge cat ways and mounting main cables. The construction method comprises the following steps of: A construction preparation, building tower bodies, pilot rope winches, concrete anchors and main winches on two constructional banks; B, building pilot ropes; C, building traction ropes, respectively drawing one ends of the transition ropes of the main winches arranged on two banks to tops of towers, drawing one end of the traction rope arranged on the top of the tower on one bank to the top of the tower on the opposite bank through the pilot ropes, and enabling end heads of the two traction ropes to be connected; and starting the main winches on two banks, enabling the main winch on one bank to wind and the main winch at the other end to unwind until the traction ropes are built. The method has the advantages of being fast and convenient in mounting, safe in construction, short in navigation chan
