This standard specifies the types, functions, shapes, colors, light qualities, illustrations and distribution principles of aids to navigation on indand waterways (hereinafter referred to as indand waterways aids to navigation).
This standard is applicable to indand waterways aids to navigation distributed in the navigable waters of rivers, lakes and reservoirs of the People's Republic of China. For some special navigable waters, separate regulations may be made based on specific circumstances after approval. 2 Reference Standards
(G135864 Main Dimensions of Inland Waterway Aids 3 General Principles
3.1 Inland waterway aids are important aids for ships to navigate safely in inland waterways. The main functions of inland waterway aids are to indicate the direction, boundaries and obstructions of inland waterways, reveal relevant waterway information, and point out safe and economical waterways for ships to navigate. 3.2 Principles for determining the left and right banks of a river: Determine the upstream and downstream of a river according to the direction of the water flow. Facing the downstream of the river, the left side is the left bank, and the right side is the left bank. The left and right sides of the river are the right.
For rivers with unclear flow direction or different flow directions in different sections, the upstream and downstream are determined in the following order: the end leading to the seaport is the downstream
b. The end leading to the main stream is the downstream;
The south or east end of the river is the downstream;
d. The upstream and downstream are determined by the main flow direction between the main ports at both ends of the route. 3.3 The inland river navigation marks on the left and right banks must be distinguished, and their colors are: white (black) on the left bank and red on the right bank ; The light color is: green light (white light) on the left bank and red light on the right bank. There is no need to distinguish between the left and right banks. The inland waterway navigation marks are determined by the brightness of the background. Their colors are: red (black) where the background is bright; white where the background is dark.
The quality of inland waterway navigation marks shall comply with the provisions of Appendix A (Supplement). 3.4 Inland waterway navigation marks are divided into three categories according to their functions: navigation marks, signal marks, and special marks. The legend of inland waterway navigation marks is shown in Appendix B (Supplement). 4 Navigation marks
Navigation marks indicate the direction of the waterway, The signs of boundary obstructions include ten types, such as river crossing mark, coastal mark, guide mark, transition guide mark, fore and stern guide mark, side mark, left stone navigation mark, position mark, flood mark and bridge mark. 4.1 River crossing mark (Figure 1)
4.1.1 Function
Indicates the starting point or end point of the river channel. Instructs ships coming from the opposite bank to sail along the bank when approaching the mark: or indicates to sail along the bank. Approved by the State Administration of Technical Supervision on December 4, 1993 and implemented on September 1, 1994
GB 5863—93
The incoming ship turns to the other side when approaching the mark. It can also be set at the intersection of the upper and lower river crossing channels in the main half to instruct the ships coming from the other side to go to the other side when approaching the mark. 4.1.2 Shape
Two square top marks are installed on the upper end of the benchmark, facing the upper and lower channels respectively. If the river crossing channel is too long and the mark is not obvious enough, a trapezoidal sign can be installed in front of the benchmark, and the trapezoidal sign faces the direction of the marked channel. The river crossing mark can also be installed on a buoyant base as a buoy.
4.1.3 Color
Figure 1 Crossing mark
Left bank: top mark and trapezoidal sign are white (black), and the pole is white and black stripes. Right bank: top mark and trapezoidal sign are red, and the pole is red and white stripes. The color of the trapezoidal sign can also be determined according to the brightness or darkness of the background. The left bank with bright background is black, and the right bank with dark background is white. 4.1.4 Light quality
Left bank: white, Morse signal "A" flashes (·一); right bank: white, Morse signal \N\ flashes (一·). Or left: white, Morse signal \M\ flashes (一一): right bank: white, Morse signal \D\ flashes (一,,). 4.2 Coastal mark (Figure 2)
4.2.1 Function
Indicates the shore where the coastal channel is located, and instructs ships to continue to sail along this shore. 4.2.2 Shape
A spherical top mark is installed on the top of the pole.
4.2.3 Color
Left bank: top mark is white (black), and the pole is white and black stripes. Right bank: top mark is red, and the pole is red and white stripes. 4.2.4 Light quality

4.3. 1 Function
CB 5863—93
The guide line formed by the two marks in front and behind the mountain indicates the direction of the channel, instructing ships to navigate along the channel marked by the guide line. 4.3.2 Shape
The top of the poles of the first two markers are each equipped with a square top marker, and the top markers are facing the direction of the waterway. If the waterway marked by the wire is too long and the marker is not obvious enough, a trapezoidal sign is installed in front of the pole, and the trapezoidal sign faces the direction of the marked waterway. In the waterway marked by the wire, the front marker should be slightly lower than the rear marker when seen by ships in the daytime, and the rear marker should not be blocked by the front marker at night. The height and distance between the front and rear markers should be adapted to the length of the waterway marked by the wire to maintain the sensitivity of the guide marker. The calculation method of inland river guide markers is shown in Appendix E. If the slope of the marker site is relatively steep and the height difference between the front and rear markers is too large, a marker with an alternating shape can be added between the two markers. 4.3.3 Color
The color of the top mark, the pole and the trapezoidal sign shall be determined according to the lightness and darkness of the background. The bright background shall be red (black), and the dark background shall be self-colored. The central vertical stripe of the red (black) trapezoidal sign shall be white, and the central vertical stripe of the white trapezoidal sign shall be black (red). 4.3.4 Lighting quality
The front and rear marks shall be white with single-sided fixed light. If the lighting of the back is complicated and white light is easily confused, red single-sided fixed light can be used. 4.4 Transition guide beacon (Figure 4)

buildings and construction prohibited navigation, etc., which require navigation control. The signal is used to control the one-way sequential navigation of upstream or downstream ships or prohibit navigation. 5. 1. 2 Shape
It consists of a pole with a crossbeam and a signal, and the crossbeam is perpendicular to the line of sight. The arrow-shaped navigation signal bow hung at one end of the horizontal beam, with the arrow pointing downward, indicates that the downstream ship is allowed to pass through, and the arrow pointing upward indicates that the upstream ship is allowed to pass through. The signal for prohibiting navigation is two vertically hung triangular cones with the cone tip facing upward. 5.1.3 Color
The pole and the horizontal beam are white and black diagonal stripes, the arrow or triangular cone is red, and the arrow shaft is black (white). 5.1.4 Light quality
A red and green fixed light group signal hung vertically at one end of the horizontal beam: the green light is on the top and the red light is on the bottom, indicating that the downstream ship is allowed to pass through; the red light is on the top and the green light is on the bottom, indicating that the upstream ship is allowed to pass through. The upper and lower red lights indicate that the ship is prohibited from passing through. For the traffic signal beacon that controls the entry and exit of ships in the navigation building, a group of red and green single-sided fixed lights can also be set at the upper and lower ends of the navigation building, with the lights facing the direction of the approaching ship. The red light indicates that the ship is prohibited from passing through, and the green light indicates that the ship is allowed to pass through. Red and green flags can also be used instead of red and green lights during the day.
