The pier is the defender of the port

The life of cities located on the banks of large bodies of water directly depends on the influence of large water. High humidity, seasonal temperature changes, winds blowing from the sea - all these impacts are experienced by the inhabitants of the coast. It is inherently associated with the sea and the economy of such settlements. Especially it concerns those cities in which there are ports. The cities with developed tourist infrastructure stand apart. Each of them has its own characteristics. But one thing unites them - the desire to protect themselves from negative natural influences. In order to minimize them, there are a number of measures, as well as a whole complex of protective structures. Refers to them and they say. This special structure is designed to protect the shore from the incoming high waves and not to allow large ice floes to reach it. Let's try to understand what moles are, what their role in the life of marine cities, what they are.

What is a pier

This word has a foreign origin and is literally translated as a "mound." The structure is a formed strip, starting on the shore and extending into the depths of the reservoir. This is the main difference between a breakwater and a breakwater that does not have a land link with the shore.

Why you need moles

The main task of the mole is to protect the water area from the invasion of high waves. Rolling on the mound, the waves break up and fall into smaller ones. The part of the mole leaving the sea is usually slightly thickened and raised above the water level no less than a meter. It must contain a signal light or a beacon. This is necessary to ensure that in the dark time the mole did not crash vessels. In addition to the main function, the moles perform several additional ones. For example, ships can be moored to them, elevators and other equipment can be installed on them. And these protective structures have always attracted fishermen, lovers of couples, artists, photographers ...

Types of moles

The design, height, length of the malls, their number and shape - all this is determined by many factors. The geographical location of the port, its profile, hydrological regime play a role. Taking into account many factors, a mole is constructed. It is necessary for him to fulfill his mission in the best possible way. There are three main types of moles: sloping, vertical, combined. A sloping pier is a structure, built of stone or concrete. Vertical represents two walls of slabs, stone, reinforced concrete. Combined combines the characteristics of the previous two types.
