Embodiment 1

[0011] Embodiment 1, building a city wall type building type flood control embankment in the "hanging river above the ground" section of the Yellow River. The river section runs from east to west, and the distance between the north and south banks of the Yellow River embankment is 12km. The main river course leans on the embankment 2 on the left bank, and the embankment is constructed with a masonry engineering face protection, and is additionally built with solid dams and stacks as protection. The embankment 1 on the right bank is an ordinary earth-stone embankment, which is an old dike from the Ming and Qing Dynasties, and there are many hidden dangers. Therefore, the construction plan of retaining the dike 2 on the right bank and abandoning the embankment 1 on the right bank is chosen. The cross-section of the new main channel 3 after dredging is a composite trapezoid with the bottom up. The design width of the river channel is 240m, the deep navigation channel in the midd...

Abstract

The invention provides a method for constructing a building type flood bank and reclaiming and utilizing a river bottomland. According to the method, a row of closely connected buildings with a flood blocking function are constructed as the building type flood bank on a stream segment with bottomland developed and cultivated land and villages on the bottomland and close to the drainage line of the river on the basis of whole line dredging of a lower course of the river. After the flood bank is constructed, the bottomland is reclaimed into permanent safe high-standard farmland or a new urban district and high-tech industry park with high land additional value. Compared with the traditional rockfill dam, the building type flood bank has the advantages of a high flood resisting safety factor and a high investment return rate. The functions of navigationon the riverway, irrigation and power generation through river water are realized, the distance between the dams on the two banks is shortened and the cost of constructing the river-crossing bridge is reduced to 5-20% of the original cost. The new type urbanization and the river pollution prevention are realized in the flood plain. The original dirty, disorderly and bad bottomland environment is turned into a brand new beautiful place.

Description

(1) Technical field [0001] The invention relates to the technical field of building a building-type flood control embankment and transforming and utilizing river beaches. (2) Background technology [0002] The frequent occurrence of floods in the lower reaches of the river is mainly caused by two reasons: one is the serious siltation of the river course and the deterioration of flood carrying capacity, and the other is the old and fragile dikes. Since there is no fast and effective dredging equipment, the comprehensive dredging work of the river has not been really carried out so far. And because the traditional method of building earth-rock dams has a large amount of engineering and low economic returns, it is difficult to attract funds to invest in embankment projects. The increase in population and the scarcity of land have led to an increasing number of people who venture to live and carry out production and living activities on river flats. The lower reaches of the Ye...
