Description

Technical Field

[0001] The utility model relates to the technical field of urban construction, in particular to a sunken green space overflow system. Background Art

[0002] At present, in the construction of "sponge city", the existing overflow system mostly adopts the structure of inspection wells or rainwater outlets. This overflow structure is more suitable for facilities such as sunken green spaces or rainwater gardens with larger areas. However, for linear sunken green spaces, due to the narrow width of the green space, the overflow outlet of the traditional inspection well structure is limited by its own size. The common overflow well size is about 1m. Sometimes the overflow well size is basically the same as the width of the green space, which makes the construction complicated and also affects the landscape effect. Utility Model Content

[0018] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] Please refer to the attached Figure 1 , combined with a specific embodiment, it is explained as follows: The utility model describes a sunken green space overflow system, including an overflow pipe 2, the overflow pipe 2 is vertically arranged inside the foundation, and the 200mm area on both sides of the overflow pipe 2 is compacted with clay 7.

[0020] The top of the overflow pipe 2 is provided with an overflow port 1, which is located above the design water level 6. Specifically, the top of the overflow pipe 2 is in the same horizontal plane as the design water level 6. The overflow port 1 is a pipe-type structure, and a plurality of overflow slits 101 are opened on the circumferential wall of the overflow port 1. The plurality of overflow slits 101 are arranged vertically.

[0021] The bottom end of the overflow pipe 2 is connected to an overflow connecting pipe 3 through an elbow pipe 5; the overflow connecting pipe 3 is horizontally arranged at the inner bottom of the foundation, and the overflow connecting pipe 3 is connected to the rainwater pipe network. The elbow pipe 5 is arranged in a concrete fixed pier 8.

[0022] The use principle of the utility model: The overflow system is mainly used for sunken green space or rain garden. Take the sunken green space as an example: the narrow roadside green belt is used as a sunken green space for sponge city facilities. The width of the green space is 0.5m, and the diameter of the overflow well is about 1m. The overflow pipe 2 is vertically embedded in the main body of the sunken green space, and is connected to the drainage system through the overflow connecting pipe 3 horizontally embedded in the bottom of the main body of the sunken green space. An overflow port 1 is installed at the top of the overflow pipe 2. The height of the lower end of the overflow port 1 from the ground of the sunken green space is the lowest water storage level, and the distance from the top of the overflow port 1 to the ground of the sunken green space is the highest water storage level. The lowest water storage level is the design water level 6. When the rainwater exceeds the design water level 6, the overflow port 1 can overflow the water through the overflow gap 101, and send it to the rainwater pipe network through the overflow pipe 2, the overflow connecting pipe 3 and other components. At the same time, the overflow port is provided with an overflow gap structure which can also filter plant stems and leaves to prevent clogging of the pipe. It can be seen that the overflow system is a single-tube overflow system, and its pipe diameter and overflow port size are smaller than the currently commonly used concrete overflow well size, which does not affect the appearance and has low construction difficulty, high practicality, and is suitable for promotion.

[0023] In one embodiment, the top of the overflow port 1 is a closed structure, and a vent hole 4 is provided at the top of the overflow port 1. By providing the vent hole 4, the drainage effect can be further improved.

[0024] In one embodiment, the concrete fixing buttress 8 is a square structure. The volume of the concrete fixing buttress 8 is 400mm*400mm*400mm. The structure of the concrete fixing buttress 8 is more reasonable and convenient for construction.

[0025] In one embodiment, the overflow pipe 2 and the overflow connecting pipe 3 are DN100 or DN200 drainage pipes. The overflow pipe 2 and the overflow connecting pipe 3 are more versatile and easy to obtain.
