Description
Technical Field
The utility model relates to a hydraulic and hydroelectric engineering technical field, concretely relates to urban river way is ladder step structure down.
Background
The city embankment engineering construction is an important component of city construction, is not only related to the beauty of cities, but also closely related to the life and property safety of people, and is a practical long-term flood control measure. Therefore, with the advancement of modernization and the introduction of new targets for sustainable urban development, the urban embankment construction needs to meet the multiple requirements of advanced technology, economy, reasonability, safety, applicability, beauty, hydrophilicity and the like so as to effectively serve the urban development.
The construction of city river embankment is influenced by many factors such as blue line planning and land utilization planning, and in order to meet the high-standard flood control requirements of cities, vertical revetment types such as vertical retaining walls and pile plate walls are mostly adopted. The steps of going down the river are used as main structures of the dike, are arranged at unequal intervals along dike routing lines, are main channels for connecting a dike bank line and dike feet with the upstream surface, and have the main functions of daily operation management and maintenance of a river channel, cleaning and maintenance of the river channel, meeting the requirement of hydrophilicity by combining landscape requirements along the line and the like.
In the prior art, two types of step descending forms are generally provided, namely: the ladder step is perpendicular to the water flow direction, gradually reduces the elevation and extends into water according to a certain slope ratio, the mode is mainly suitable for the upstream face of the slope type dike, and the ladder step mainly adopts materials such as cast-in-place concrete, precast concrete blocks, masonry and the like. The second form: the ladder step gradually reduces the elevation along the water flow direction according to a certain slope ratio and extends into the water. This kind of mode is mainly applicable to traditional vertical type revetment, and the ladder step is mainly cast in situ concrete structure.
However, the two forms of the steps in the river have the following problems:
(1) the urban river revetment is high, and if a traditional mode that the river descending ladder step is arranged in a direction perpendicular to the river channel is adopted, a wider river channel space needs to be occupied, and adverse effects are caused on river channel flood discharge;
(2) the river descending ladder step is arranged on the bank side along the water flow direction, so that the space between the two banks needs to be occupied, and the whole construction of the bank line is not facilitated.
(3) The traditional embankment is single in river ladder step type and function, and in urban construction, the landscape environment is relatively weak in function and poor in coordination with the surrounding environment.
(4) The tradition is gone down the river ladder step and is not had platform or platform singleness and set up in the toe, and when the river course water level rose, the platform was easily submerged under water, unable normal use, and it is relatively poor to the adaptability of environment.
