What's the name of the stake that tied the boat on the ancient pier?

The wooden stakes used to tie boats on ancient docks are called bollards.

Mooring post is a facility installed in the superstructure of wharf for mooring ships. Mooring columns are generally made of metal materials, so they are named after being columnar.

The bollards are designed and selected according to the berth capacity and the wharf structure type, so as to meet the requirements of safety, reliability and convenience for berthing, berthing, shifting and turning. The bollard consists of shell, anchor rod, nut, washer, anchor plate and column core filler. The bollards are divided into cast iron (HT200) and cast steel (ZG230-450), with specifications of 50KN-2000KN.

According to the use, there are ordinary bollards, storm bollards and experimental bollards.

Generally, the center of the common ship column is about 0.5 ~ 0.8 meters away from the front line, and the distance is too close, so it is easy to be hit by the ship when approaching and leaving, and the cable operation is unsafe; Too far back will hinder the operation of loading and unloading machinery and damage the cable. For the outfitting and ship repairing wharf, due to the junction box and other facilities at the front, the bollards are required to be slightly away from the front line, about 0.8 ~1.0m..

Storm columns are used to anchor ships during storms and are usually located behind the dock. Some ports have no storm bollards because the probability of typhoon is small, or ships do not take shelter from the wind on windy days; In some ports, in order not to hinder the operation of loading and unloading transport machinery, storm bollards are not installed at the back of the wharf, but the size of ordinary bollards is increased, so that they can be used in strong winds.
