Pier design

Reply 1# kuaileren should have a fairly accurate understanding of the typical dimensions of vehicles. I once designed a loading dock, only for the vehicles used for maintenance to be unable to turn around

Reply to 2# shzx603: The person above has a lot of experience; could they explain it in more detail?

Reply to 3# kuaileren: One of the projects we are working on is related to wharf piers. What I mean is that it’s necessary to determine the turning diameter for construction or maintenance vehicles, so as to ensure they can enter and exit easily. It might be a bit different from what you mentioned; we can discuss this further

If you find a code for tank farm design, everything will become clear; the main thing to consider is the safe distance between the unloading nozzles, while other factors are not that important. . The last flexible hose is 20 meters away from the vehicle barrier, and the vehicle barrier is 15 meters away from the fence.

It mainly implements the \"Code for Design of Oil Depots\" GB50074-2002 and the \"Code for Design of Railway Loading and Unloading Facilities for Petrochemical Liquid Materials\" SH/T3107-2000.

The design of railway loading trestles must comply with the following regulations: 1. Railway mechanical regulations. 2. Railway Dangerous Goods Regulations. 3. The structure of the oil cleaning vehicle, i.e., the spacing between the oil drainage holes. 4. The height of the oil cleaning vehicle (the height of the platform should be the same as that of the pier platform). 5. The actual loading and drainage capacity. 6. Length of the oil cleaning vehicle, etc.

Who has designed steel structure railway trestles? I have a design request and need help

I’m looking for information on this topic; everyone’s answers are very insightful

Interim Technical Requirements for Safety Equipment and Facilities for the Handling of Hazardous Goods on Railways and on Dedicated Lines (Dedicated Railways)

6.1 Stack bridges and dip pipes 6.1.1 The stack bridges for loading and unloading tanked goods, along with their associated pipelines, should be arranged in a horizontal layout. When constrained by topographical conditions, individual loading and unloading trestles and their associated tracks can also be arranged in a linear configuration. 6.1.2 Loading and unloading trestles for liquefied hydrocarbons, light oils, toxic substances, and corrosive substances should be provided separately ； When loading and unloading operations are not carried out simultaneously, liquefied hydrocarbons and light oils can be arranged on the same bridge. Liquids with similar properties can be loaded and unloaded using the same bridge. 6.1.3 Stack bridges and their accessories shall be constructed from fire-resistant, corrosion-resistant, and water-impermeable materials, with a fire resistance rating of not less than grade 3. 6.1.4 The deck of the trestle should be at a height of 3.5 m above the rail surface. Safety railings should be installed on the pier. Ladders for ascending and descending the pier should be installed at both ends of the pier and every 60–80 m along it. 6.1.5 The length of the stack bridge depends on the number of vehicles loaded or unloaded at one time (i.e., the number of parked vehicles). Width of loading quay: The width for loading a single small hose on one side should not be less than 1.5 m. The width for bilateral loading should be 2–3 m. The loading length on both sides of the large hose should be 4 m. Width of the unloading quay: When upper unloading is used, the unloading width on both sides should be 2–3 m, while the unloading width on a single side should not be less than 1.5 m. When using a bottom-unloading method (such as for crude oil), the width of the unloading platform should be 1.5 to 2 meters. 6.1.6 In the areas where flammable liquids and gases are loaded and unloaded, the distance between the loading arms on adjacent piers shall comply with the following requirements: 1. The distance between the loading arms on piers used for Class A and Class B liquids and those on adjacent piers shall not be less than 10 m ； When Class A B and Class B liquids are loaded and unloaded in a sealed manner, their fire separation distance can be reduced by 25%. 2. The distance between the dip pipes of two adjacent trestles for Class C liquids should not be less than 7 m. 3. The distance between adjacent transfer pipes at two loading/unloading trestles on the same railway loading/unloading line shall not be less than 24 m. 4. For goods with incompatible properties or firefighting methods that are contradictory to each other, the straight-line distance between the loading and unloading nozzles must be at least equal to the spacing between 4 nozzles. 6.1.7 The trestle should be arranged parallel to the loading and unloading line, and an easily operable emergency shut-off valve should be installed on the liquid transfer pipeline at a distance of more than 10 m from the edge of the trestle. 6.1.8 In areas where the average annual precipitation is greater than 1,000 mm, or where the average maximum temperature in the hottest month is above 32 °C, a rainproof or heat-proof shelter should be installed on the trestle. 6.1.9 The distance from the start of the straight section between the first flexible hose on the stack bridge and the track shall not be less than 1/2 of the length of the tank car. The safety distance from the center line of the coupling at the leading vehicle in the tank car train on the loading/unloading line to the stop signal of the railway switch ahead shall not be less than 31 m ； The safe distance from the center line of the coupler at the terminal parking position to the car stopper on the loading/unloading line shall be no less than 20 m. The distance from the loading/unloading flexible hose to the railway gate should not be less than 20 m. The distance between the crane positions at both ends of the pier and the end of the pier should be 3 m. The spacing between the flexible hoses of the same material on both sides should be determined based on the length of the tank truck. 6.1.10 For the loading of liquefied hydrocarbons and flammable liquids, the number of small dip pipes should be no less than 5; for materials that involve occupational exposure to toxic substances as well as corrosive liquids such as acids, alkalis, and salts, the number of small dip pipes should be no less than 2. The loading quay for small hose trailers should be equipped with one loading/unloading crane position to prevent overloading. Loading and unloading cranes for low-temperature liquefied gases should be provided separately.
