Description

552338 B7 V. Description of the invention ([Field of the invention] The present invention relates to a system for preventing sedimentation at the water intake of a river or a reservoir, first of all, it refers to a method for blocking sand or gravel on a river or an intake of a reservoir. Clean up to avoid siltation in rivers or reservoirs. [Explanation of the know-how] There are many mountains in Xikou Bay and less flat land, so the rivers that are prone to rapids are quite Liuxi '. In addition, the probability of heavy mountain rain is high, so many rivers Upstream = rapid flow of energy into the stream, making sand and gravel on the mountain follow the rapid loss zone ^ However, after the sand and gravel flow to the downstream, it is very likely that the rapid and L attenuation will cause siltation, and then If the river is clogged, the lighter ones may cause river diversions, and the heavy ones may cause river floods and other disasters. Therefore, many silting places in the middle and lower reaches of rivers will be used for blocking: dams and other types of blocking projects, and regularly cleaned Maintenance, thereby preventing floods and disasters. However, usually, sand dams and other blocking methods have a long construction period and long-term cost. All the sizes are blocked, so it will soon reach the saturation level without use benefits. Moreover, if the silt is removed by a -like excavator, the sand and dam will accumulate the sand too quickly, which will cause the relative removal of the gravel. The cycle is short, so it has the disadvantages of high cost and long working hours. Therefore, the applicant of this case believes that ~ Feng Yu / Kechuan is equipped with a device for blocking sand and sand at the middle and lower reaches, and every __ blocking device is successively Reducing the size of the blocking sand and gravel 'that is, multiple sheds can be blocked' and then cleared and transported through each place individually, which will definitely reduce the negative cost of cleaning and transportation #, and it will also be better in dredging the river. "Reservoir" is a kind of water conservancy project for flood storage and regulation of water flow.

Description of the invention (2 Buildings can be used to provide water for people's livelihood, irrigation, power generation and fish farming. It is certainly an indispensable building facility in human life. Generally speaking, there are many ways for reservoirs to store water. Use dams to stop the water when the river flows too much, and then guide it into the reservoir's water storage pond, or build a water storage pond directly at the meeting point of the river, and then build a dam to adjust the water volume, so that the reservoir The water storage capacity can be kept constant, so that the people's livelihood, industrial water or irrigation water can be provided. However, the way of introducing water into the reservoir's water pond often occurs when the water flowing from the upstream source of the river entrains the earth and rocks along the reservoir. The diversion channel at the water inlet enters the water storage pond, and then accumulates in the water storage pond, which affects the water storage capacity of the reservoir. In particular, the reservoirs are usually located between the valleys. In addition, heavy rains often fall in the mountain areas, making it easy for a large amount of earth and rocks to follow. The water flow from the upper reaches of the river is washed down, and flows into the water diversion channel at the inlet end of the reservoir, and then enters the water storage pond from the water diversion channel. Its service life is also greatly affected. However, in view of the fact that the reservoir is susceptible to soil and rock deposition, which shortens its service life, the diversion channel at the inlet of the reservoir will be provided with a hold-up process to reduce the flow of earth and stones into the storage pond. For example, non-permeable bodies such as bad sand storage and continuous submerged dams, or pervious bad bodies such as comb soil are installed on the water diversion channel to achieve the purpose of increasing the roughness and obstruction of the river bed and depositing earth and stones. However,- In order to avoid damage during earth-rock impact, the dam roof of the dam body needs to be enlarged to increase the impact strength. Therefore, whether the shed is slumped or the size of the comb dam is quite large, not only the construction period is quite long, but also the construction cost. It's also quite high. In addition, all kinds of collapsed structures are mixed.

Description of the invention (3) Condensate is constructed, and the impact of earth and stone with the flow of water has a strong destructive effect on the concrete structure (the hardness of the stone is greater than that of the concrete structure). If the earth and stones in the water diversion channel at high velocity and high impact force, they will directly impact the surface of the dam, causing wear and damage. Therefore, various types of dams are not used in practice. [Summary of the invention] Therefore, the main object of the present invention is to provide a system for preventing sedimentation at the water intake of a river or a reservoir with a short construction period and simple construction, for blocking, sedimentation of a river flow or a reservoir inflow.
