河道治理的方法 Method of river control 1 從源頭上進行治理 1 from the source of governance 我們應該先從源頭抓起。河流在山澗中匯集而成,而一旦遇到暴雨或者連續的陰雨天,雨水就會順流而下,而河流兩邊的松散尤其顆粒大的固體物質就會隨著雨水直接進入河道,長年累月可以使河床抬高,而部分大顆粒就會在河道當中形成堆積,擠占河道,從而迫使河流改道泛濫。我們針對這一情況應在保持現有良好植被,進一步增加植被的覆蓋率,禁止亂砍亂伐,新建工程務必做好水土保持工作,只有河道源頭的植被增加了,才能更好的涵養水分,緩解水流的速度,而且對于土壤起到一定的保護作用,使泥土不易被雨水沖走。 We should start from the source first. Rivers come together in a mountain stream, and once a rainstorm or continuous rainy day, the rain will flow down, and the loose, granular, solid material on both sides of the river will enter the river directly with the rain, and the river bed can be raised over the years, and some large particles will accumulate and accumulate in the river. The river, which forces the river to flood. In this case, we should maintain good vegetation, increase the coverage rate of vegetation, prohibit cutting down and cutting down, and make sure that the new project must do the work of soil and water conservation. Only by increasing the vegetation of the source of the river, can we better maintain the water and ease the speed of the water, and have a certain protective effect on the soil. The soil is not easily washed away by the rain. 2 對中小河道進行有效治理 2 effective management of small and medium river 在對中小河道進行治理時,我們需要根據河道的不同情況來采取不同的治理方法。對于河道斷面較窄的地方,則需要進行拓寬處理,而對于曲折較大的要河段,則應該進行取直處理,對于堵塞地段,應進行有效的疏通。做好護岸工作,對于沖撞嚴重的河道,需要采用于砌塊石來進行護岸,而且需要立砌,保持磚面的平整度。對于一些堤壩由于受到沖擊性較大,所以需要將砂石用鐵線網罩住,對于沖刷嚴重的河段,則需要采用漿砌石來進行護岸,但由于這種護岸比較容易在受到沖刷時而受到不同程度的破壞,所以其基礎需要進一步加深。而對于沖刷特別嚴重的河段,以上各種方法已無法有效的抵抗沖擊力所帶來的影響,所以需要采用鐵絲石籠進行護岸??梢岳梅謮K拼裝法及整體鋪蓋法進行,這兩種方法都能起到護岸的,有效的避免了大較大沖擊力下對河岸所帶來的侵蝕。 In the course of harnessing the middle and small river courses, we need to adopt different treatment methods according to the different situations of the river courses. For the narrow section of the river, it needs to be widened, and for the large and complicated section of the river, the straightening treatment should be carried out, so it should be effectively dredged for the block. To do well revetment work, it is necessary to use block stone to carry out revetment for severely damaged river courses, and also need to erect to keep the evenness of brick surface. Because of the great impact of some dikes and dams, it is necessary to cover the sand and gravel with a wire mesh. For the severe scouring of the river section, the mortar is used to protect the bank, but because the bank is easily damaged by the scour, the foundation needs to be further deepened. And for the scouring very serious river section, all the above methods have been unable to effectively resist the impact of the impact force, so the need to use wire cages to protect the bank. The two methods can be used to protect the bank, which can effectively avoid the erosion of the river banks under large impact.
