[0021] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0022] Example:

[0023] like Figure 2-Figure 6 As shown, the siphon drainage ditch with both water storage and flood discharge functions comprises a drainage ditch 1 and a plurality of drainage pipes 2 arranged at intervals in the drainage ditch 1, one end of each drainage pipe 2 extends into the drainage ditch 1 and extends upward for a distance along the height direction of the drainage ditch 1; the other end passes through the drainage ditch 1 and is connected to a water collection well 3;

[0024] Each drain pipe 2 is provided with a siphon sleeve 4 in the portion inside the drain ditch 1;

[0025] The top of the siphon sleeve 4 is blocked and the bottom is open; there is a spacing distance between the top of the siphon sleeve 4 and the end of the drain pipe 2 located inside the drain ditch 1;

[0026] The bottom of the siphon sleeve 4 is fixedly connected to the bottom of the drain ditch 1 , and the top is fixedly connected to the end of the drain pipe 2 located in the drain ditch 1 .

[0027] The main innovation of the utility model is that, by utilizing the siphon principle, the siphon sleeve 4 and the drainage pipe 2 form a communicating vessel, and when rainwater is stored to a certain height in the drainage ditch 1, siphon drainage is performed to reduce the peak flow and effectively drain water quickly.

[0028] More specifically, the size of the siphon sleeve 4 can be adjusted according to the width and depth of the drain ditch 1, and the size and spacing of the bars on the siphon sleeve 4 can be adjusted to adjust the flow rate. According to the height relationship between the siphon sleeve 4 and the internal drain pipe 2, a siphon sleeve 4 can be set at a certain distance according to the size of the water volume in the drain ditch 1.

[0029] A grating plate 5 is provided at the end of each drain pipe 2 located in the drain ditch 1, wherein a siphon sleeve 4 is provided on the outside of the drain pipe 2, and the grating plate 5 thereon is supported on the top of the corresponding siphon sleeve 4 by channel steel, so that a gap is formed between the drain pipe 2 and the siphon sleeve 4.

[0030] The siphon sleeve 4 and the drain pipe 2 form a communicating vessel. The siphon sleeve 4 is fixed to the bottom of the drain ditch 1 by bolts. The drain pipe 2 and the top of the siphon sleeve 4 are supported by the connecting parts of the grating plate 5 and the channel steel, and can also filter water. The function of the siphon sleeve 4 is to prevent air from entering the drain pipe 2 and destroying the water seal.

[0031] Furthermore, the bottom of the siphon sleeve 4 is fixedly connected to the bottom of the drain ditch 1 via a sleeve fixing member 6, and the sleeve fixing member 6 can be a bolt.

[0032] The working principle of the utility model is the communicating vessel principle, which utilizes the force phenomenon of the height difference of the liquid level, that is, utilizes the pressure difference of the water column to make the water rise and then flow to the lower place. Since there are different atmospheric pressures in the drainage ditch 1 and the rainwater collection well 3, the water will flow from the side with high pressure (the side of the drainage ditch 1) to the side with low pressure (the side of the collection well 3). Until the atmospheric pressures on both sides are equal. The siphon phenomenon can be used to quickly discharge all the rainwater in the drainage ditch 1.

[0033] The rainwater on the ground is collected in the drainage ditch 1. Because the drainage pipe extends out of the drainage ditch to a certain height, the water cannot be discharged when the amount is small. The rainwater is stored and utilized in the drainage ditch 1, so that the rainwater is retained in the drainage ditch 1, reducing the peak flow of rainwater. When the amount of water is large and reaches the height of the drainage pipe 2, the siphon sleeve 4 and the drainage pipe 2 cooperate to produce a siphon function. The same DN100 drainage pipe 2 rainwater has a drainage flow of at least 23L / s when it has a siphon function, which is 3.13 times the drainage flow of the ordinary drainage ditch 1; the rainwater siphon sleeve 4 is quickly discharged under the siphon effect; the utility model is applied to the storage and regulation of rainwater in sponge city facilities to regulate the peak flow.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
