pysäytyspuomit

Pysäytyspuomit, also known as stop logs or stop planks, are a type of water control structure used in dams, canals, and other water management systems. They consist of a series of horizontal beams, typically made of wood or metal, that are inserted into vertical guides or slots within a concrete or masonry structure. These guides are usually positioned across the flow of water.

The primary function of pysäytyspuomit is to temporarily block or regulate the flow of water. They can be lowered into place individually or in sequence to create a barrier. This allows for various operations, such as dam maintenance, dewatering of sections of a canal for repair, or controlling water levels for irrigation or power generation purposes. When water needs to be released, the logs are removed, typically in reverse order.

The design and material of pysäytyspuomit depend on factors such as the water pressure they need to withstand, the environmental conditions, and the expected frequency of use. Wooden logs are often used for less demanding applications due to their lower cost, while metal logs are preferred for higher pressures and durability. The efficiency and safety of their operation rely on the precise fitting of the logs within their guides to minimize leakage. Pysäytyspuomit represent a simple yet effective method for managing water flow in a controlled manner.
