(1) When the trough type large span cable tray is entered into the building from the outside, the slope of the bridge shall not be less than 1/100.
 
(2) When the cable tray is crossed with the electrical equipment, the clearance between them is not less than 0.5m.
 
(3) When the two sets of cable trays are laid in parallel at the same height, the clearance between them is not less than 0.6m.
 
(4) Draw the route of the bridge on the parallel diagram, and indicate the coordinates or positioning size and elevation of the starting point, the end point, the turning point, the branch point and the lifting point of the bridge. If the side view of the bridge laying axis can be drawn, the material statistics are Will be more precise. Straight line segment: Indicate the full length, number of decks, elevation, model and specifications. Turning points and branch points: Indicate the model and specifications of the turning board used. Lifting section: indicate the elevation change, or it can be represented by a local large sample or sectional view.
 
(5) The support points of the bridge, such as the column, the arm or the non-standard branch, the spacing of the frame, the installation method, the model specification, and the elevation, can be agreed to be listed on the plane, or the sections can be marked with different sections and single lines. Figure or large sample representation.
 
(6) The position of the cable lead-down point and the way of guiding it down. Generally speaking, a large number of cables can be led down by a vertical bent plate and a vertical lead frame. A small number of cables can be used to guide the guide plate or the lead pipe.
