Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for remediation of rivers, and more particularly to a method for constructing a bridge with a protective pier and a dike to achieve a protection bridge sign. Dikes and river formation methods for the formation of specific areas of sand and gravel. [Prior Art] According to 'when the hurricane or heavy rain hits 'the amount of rain that is often reduced in a short time', the water volume of the river becomes larger and the water level rises, so that the bridge piles exposed or embankments built on these rivers are added. The sky was emptied, and there were accidents such as broken bridges and expensive embankments. However, the protection currently applied to the bare piles of the piles is only to strengthen the structure of the piles themselves. However, the effectiveness of this method is still inconsistency, and it is still easy to have a crisis of broken bridges. In view of the above-mentioned broken bridge crisis, the reason is due to the bare foundation and the scouring of the bridge foundation. The main reason for the bare piles and the scouring is that the sand and gravel industry is mining sand and gravel in the upper reaches of the river, which makes the river unable to Sufficient amount of sand and gravel flushed to the middle and lower reaches', so that the height of the riverbed in the middle and lower reaches continues to drop, coupled with the long-term erosion of rivers and rivers, so that the bridge foundations deep under the riverbed are exposed or hollowed out by the water flow. Formed a dangerous bridge with a broken bridge. However, because the sandstone is deep on the river (4) (4), if the sandstone is too small, the riverbed will fall, causing damage to the river-like facilities (such as broken bridges), while the gravel will reduce or change the river channel, and the dredging of the fixed point will also be Wei Cheng. The administrative materials for the delivery of the package and the complicated materials, ^li^ and the embankment, (4) the age-riding and listening bridges, taking the case of the Xinleke Yuefeng in the last 17 years as an example, resulting in six broken bridges, while the 201016930 Houfeng Bridge was broken. The cost of reconstruction of the bridge is as high as 1.25 billion yuan. According to the press release issued by the General Administration of Highways, there are also four bridges, and the funds for reconstruction or reconstruction in the next five years will be as high as about 11.8 billion yuan. As shown in the first figure, the existing method for protecting bridges and dikes is mainly to set up a sand dam 2 at the downstream of a bridge 1 to moderately deposit sand and gravel to avoid river bed loss, but the height of such sand dam 2 Not high or even lower than the water surface height, not only can not maintain the appropriate sand and gravel, but when the river water volume increases, it is easy to flow over the sand dam 2, so that the sand dam 2 has little effect on keeping the sandstone. Furthermore, when the sandstone passes over the sand dam 2, the sand dam 2 itself is easily destroyed by the sand that has passed through it, so that the sand dam 2 is damaged; therefore, the above-mentioned sand dam 2 protects the pier And the effect of the dike is not obvious, and there is a lack of longevity. Moreover, since the above-mentioned sand dam 2 cannot effectively maintain the sand and gravel, there is no fixed area for sand and gravel mining, which not only cannot effectively manage the sand and gravel industry, but also makes it easier for the sand and gravel industry to sneak out the sand and gravel everywhere. In this case, the government has unilaterally spent rectifying the rivers and has been rebuilding or rebuilding bridges for a long time, but it has not been able to obtain the benefits from sand and gravel mining. © In view of the above, the main object of the present invention is to provide a river remediation method that combines protection of piers, dikes and formation of specific areas for sand and gravel collection, and utilizes a sand bar with protective piers and dikes. Achieve protection piers and dikes. Another object of the present invention is to provide a river treatment method that combines protection of piers, dikes, and formation of specific areas for sand and gravel collection by utilizing the construction of a dam with protective piers and dikes to form a specific area for sand and gravel collection, simplifying the government Management, removing a lot of sand and graves from the past. Therefore, the present invention provides a river repairing method which has both a protective pier, a levee and a specific area for collecting sand and gravel, and is provided with a sand dam at a position downstream of the bridge, wherein: the top surface of the sand dam is high The bridge needs to protect the rock bed or the embankment foundation plane of the pier. When the flood is torrent, the rock disk or the foundation will not be washed, the water will overflow the bridge deck or the embankment, and the top surface of the sand bar is concave with a predetermined depth. , the water flow in the upstream position of the sand dam may flow into the downstream position from the opening' and a plurality of dampers having a certain weight and volume are disposed at a position downstream of the dam; ® quit the sand dam at the scheduled A plurality of culverts connecting the upper and lower sides are arranged at the position, and a plurality of hollow pipes having a predetermined length are connected to the opening of the culvert toward the downstream, so that the water flow upstream of the sand dam can flow downstream from the culverts and pipes Location; In addition, the main difference between the sand dam of the present invention and the general sand dam is the difference in the structure of the dam body. If the sand dam is used, the bridge column is shorter or the dyke is more Low, spicy, the dam can not be built high, or the cost of the dam is also high, the river bed can be dug into the sand storage tank in the dam, and the sandstone can be shaped to collect a specific area, and the collected sandstone is sold. Revenue, the sandstone in the area is not often a reservoir, and the long-term goal of protecting the bridge or the embankment is reached. Therefore, the sand dam that implements the present invention will be able to repay the profit-making business that is profitable and public. Therefore, if the sand dam is short because the bridge column is short or the dyke is low, the collapse cannot be built high, or the cost of the dam is also high, the deep river bed can be dug in the upper part of the bridge or in the safe area of the levee foundation. If necessary, the surrounding area is reinforced and becomes a sand storage tank for storing more sand and gravel. Because the sand storage tank is located in the reservoir, it will not affect the upstream water flow, and will not affect the erosion of the upstream riverbed, but the town will be more adequate to prevent the sand and gravel from flowing out of the dam and scouring the downstream riverbed. 201016930 [Embodiment] In order to enable the reviewing committee to have a better understanding and recognition of the features and features of the present invention, the following preferred embodiments are illustrated and described below with reference to the drawings: The preferred embodiment provides a river remediation method which has both a protection pier, a dike and a specific area for sand and gravel collection, wherein: a sand trap 10 is arranged at a suitable position downstream of a bridge 100, the sand dam 1〇 has a certain height, its height is calculated by the calculation system is at least 1~6 meters higher than the 1桥1 level of the existing bridge bad rock plate, which is convenient for the height of one operation of the excavator, and will not overflow the bridge surface when it encounters flood. The sand dam 10 is provided with a predetermined depth opening 1 1 ' at a predetermined position on the top surface thereof for the water flow at the upstream position of the sand trap 10 to flow from the opening 1 1 to the downstream position. And at the downstream position of the shed tower, 1 q, the majority of the wave-blocking block with a certain weight and volume is set.

The economic benefit of the sand dam 10 . In addition, because the height of the sand 10 is higher than the height of the river, the sand that is washed by the upstream will be blocked by the sand barrier and can be deposited. The upstream location forms a catchment area, and the foundation pile of the bridge or the embankment can be avoided. So - come, naturally formed in the upstream position of the sand barrier 1 - sand and gravel collection m = control = degree mining sand, and because the sand dam is high out of the river ί::, room: this The large-scale machine 13 required for the mining of sand and gravel (such as the location of the excavation surface for mining, and more directly hiding from the column of the sand-blocking dam 10 can be tightly greened) can be used to eliminate the water on the 1G of the sand-blocking dam.

This will form a 201016930 slope that protects the sand dam. It can be used for impedance erosion, and the vicinity of the downstream of the sand dam 10 will not be emptied, thus protecting the structure of the sand dam. Please refer to the fourth figure, which is a second embodiment of the present invention, which provides a river treatment method for protecting a bridge pier, a levee and a specific area for collecting sand and gravel, wherein: a suitable position downstream of a bridge 100 is provided. A sand dam 2 0, the sand dam 20 has a certain height, and its height is calculated through the existing bridge The rock plate 1 0 1 level is at least 1~6 meters higher, which is convenient for the height of one operation of the excavator, and does not overflow the bridge deck and the embankment during the flood. ® The sand bar 20 has a majority connection at the predetermined position. The upper and lower culverts 2 1, and the culverts 2 1 are spaced apart from each other by a predetermined distance, and a plurality of hollow pipes 2 2 are connected to the downstream openings of the culverts 2 1 to guide the water flow upstream of the sand blocking dam 20 to The downstream river channel, and because the pipes 22 have a certain length, the water flowing out of the pipe 2 2 can be avoided to wash the foundation of the sand dam 20 to increase the service life of the sand dam 20 . The height of the sand dam 20 is higher than the height of the river, so the sand washed by the upstream will be deposited by the blocking dam of the sand dam. Thus, the sand dam is 20 The upstream location naturally forms a specific area for sand and gravel collection, so that the sandstone can be properly mined for monitoring. Since the height of the sand dam is higher than the height of the river surface, the large tools required for sand mining are required. (such as excavators, gravel handling vehicles, etc.) It is located at the top position of the sand dam 20 to facilitate mining. Furthermore, a majority of the water gates 2 3 can be installed on the sand dam 20 for the simultaneous opening of the gates 2 for the upstream water surge. 3 to achieve the effect of assisting the water volume in the upper reaches of the Xuanlang. In addition, if the sand dam is short due to the short column or the lower dyke, the dam is not available in 201016930. If the cost is too high, it can be upstream or The detachment prevention base security series, Weihe bed, solid, become a storage tank, can be used to renew more sand, and if you want to use this area, you can pump it for extraction. ❿ The invention provides a river treatment method for protecting a bridge pier, a levee and forming a specific area for collecting stones, and constructing a sand dam to stabilize the river bed, protect the pier, shape the river, and have no riverbed too high to be thinned. Sand and gravel can be deposited in a specific area as a moderate collection, so that the source of sand and gravel can be stabilized without over-excavation. Moreover, the sand-blocking dam has the function of guiding the water flow to avoid the water flow destroying the sand-splitting itself, so as to extend the barrier. The use of sand dams.
