Embodiment Construction

[0037] Embodiments of the present invention are described below with reference to the accompanying drawings, in which, figure 1 , 2 The arrows in , 4 indicate the flow direction of runoff. In addition, the "high", "low", "top" and "bottom" involved in the present invention mean that when the combined rainwater infiltration tree pond is actually applied, the direction of gravity is directed from high to low, and from top to low. direction of the bottom, in other words, in the figure 2 The direction from top to bottom identified in the center is the direction from high to low, and the direction from top to bottom.

[0038] refer to figure 1 and figure 2 , an embodiment of the combined rainwater infiltration tree pond of the present invention, for the convenience of description, the "combined rainwater infiltration tree pond" will be referred to as "tree pond" for short as follows. Including a forebay 19, the forebay 19 has a separated flow chamber 4 and a settling chamber...

Abstract

The invention relates to the technical field of urban rainwater control and utilization, in particular to a combined type rainwater infiltration tree pool. The combined type rainwater infiltration tree pool comprises a front pool (19) and a water inlet (2), wherein the front pool (19) is provided with an abandon flow chamber (4) and a sediment chamber (5) which are separated; the water inlet (2) is selectively communicated with fluid in the abandon flow chamber (4) or the sediment chamber (5), the abandon flow chamber (4) and the sediment chamber (5) are separated through a baffle plate (20), and the bottom part of the water inlet (2) is higher than the top surface of the baffle plate (20). According to the combined type rainwater infiltration tree pool disclosed by the invention, runoff rainwater on an urban road and a plaza can be subjected to pollution interception, purification and emission reduction.

Description

technical field [0001] The invention relates to the technical field of urban rainwater control and utilization, in particular to a combined rainwater infiltration tree pond. Background technique [0002] The development of urbanization has greatly changed the original hydrological cycle. Many cities have experienced serious waterlogging and urban groundwater levels have dropped sharply. At the same time, urban road runoff rainwater has brought serious water environmental pollution problems. Urban water The ecology has seriously deteriorated. [0003] In response to hydrological changes and water pollution brought about by urbanization, bioretention zones and infiltration tree ponds are suitable for the control and utilization of runoff rainwater from roads and squares. Bioretention zone technology is currently being promoted in Beijing, Shenzhen and other domestic cities application. However, in practical engineering applications, the layout of the bioretention zone is lim...
