Dam dam
is created by using the soil ground compressed tightly with mechanical or แรงคน. Earth will look solid water or water through the dam can be difficult. And strength as well as the concrete dam
.We appreciated to build a dam is a dam to store water. Because it can be built on the foundation of almost every type. Whether the foundation shall be gravel, sand or soil is not suitable for concrete dam dam con - Greek. Most of the earth is cheap.Therefore, it does not need to transport materials from other places, much like the concrete dam
.
.Some dam built with soil that looks quite like a dam. The soil is clay mixed with. To make the dam is solid water or water through the difficult. But some do not use the same kind of soil dam building.Then covered over with sand, gravel, and small stones, a shell outside on both sides. The added weight to the dam. To protect the soil in the middle part and to choose the dam with soil and material of any type.And the type of material to make use of the area's main
.
.In the project planning and design on earth dam. Criteria of engineering used to hold as a guideline, is the dam must be safe. The water does not overflow across the dam. By the spillway at the dam.To have the ability to drain much enough. Control for reservoir water level is not so high overflow across the dam. The dam will have slope of dam slope on both sides strengthen without scroll down.Not to store water during high water. During reservoir water levels decrease sharply with
.
.In the aspects of the foundation of the dam. Must not the foundation of the dam to hold press per unit area than the foundation that will endure. To prevent the foundation of the dam collapse and harmful to the dam.There are very strong and transported soil to move or float downstream to the water on the downstream. And if there's water coming from the reservoir. It has small volume to make reservoir water lost.The foundation of the dam each tend to vary. Some may be in solid rock or soil solid water. Which is the foundation for the dam foundation. Some may be sand, gravel and sand mixture sediment deposition.But no problem about the settlement. Which may be designed to prevent water through the dam under more special, and also the foundation, some may be sediment sand and clay).But no problem about water pass through, therefore, may need to consider the design to prevent ฐานรากมี settlement as well
.Earth dam, built in the sample
blocked the river, Chang Klang District, Uttaradit province is the first dam dam of
high 113.6 meters. Dam long 810 meters, hold water 9510 million cubic meters high. 113.6 M.Long 510 dam, construction began on the 2506 completed the 2515 can produce electricity, 375 000 kilo watts, the water electricity production. Will flow into the river. Used for planting in the project area, an area of about, 600 Phitsanulok000 RAI in the project area and big river, combined with the Baghdad area, about 7 500 000 farm, in the rainy season, and about 3 000,,000 RAI in the dry season. It also helps to relieve flood in the river basin and the Chao Phraya River with Bhumibol dam flood reduced. And in the water transport as well
