Description

Technical Field

[0001] The utility model relates to the technical field of environmental engineering, and more specifically, to a siphon type tree hole drainage device. Background Art

[0002] Roof rainwater in cities is an important rainwater resource, and new practices such as disconnecting building rainwater pipes and connecting them to high-level flower beds have been proposed. High-level flower beds are common greening measures in residential areas. With the development of low-impact development technology, high-level flower beds are also used for rainwater storage and filtration. At present, there are some practices of high-level rainwater flower beds, which have the appearance of flower beds but lack the connotation of high-level rainwater flower beds. There are many problems, such as the impact of roof rainwater causing soil loss in flower beds and affecting the surrounding environment of flower beds, long-term water storage in flower beds drowning vegetation, and water storage in flower beds failing to reduce non-point source pollution.

[0003] like Figure 1 The figure shows the structural diagram of the existing high-level flower beds. In the figure, the flower bed floor drain is wrapped with geotextile and the inside is a DN100 blind pipe, which is easily blocked by silt and cannot collect water in the soil. In addition, the water discharged by the device through the side wall of the flower bed needs to be collected by rainwater outlets. Many flower bed side walls do not have the conditions to set up rainwater outlets (affecting the landscape effect), and it is quite difficult to repair and replace the device after it is blocked. This method is often used to drain water and protect seedlings, resulting in the phenomenon that the side wall of the high flower bed is scattered to the paved site, and the scattered rainwater contains a lot of mud, which seriously affects the landscape effect and user experience.

[0004] like Figure 2 The figure shows another structural schematic diagram of the currently existing high flower beds. The diameter of the outlet pipe of the environmentally friendly rainwater outlet is DN300, and it is necessary to reserve a large hole in the side wall or bottom plate of the flower bed, which has a greater risk of leakage and cracking; and the drainage pipe of the device is a gravity flow drainage pipe, which requires a drainage slope of at least 3%. Flower beds and flower pools are generally set in areas with high landscape requirements and are large in number. It is not feasible for many DN300 branches to drain to the rainwater well with a drainage slope of 3%, and the flow rate of the pipe network is not high, which is easy to be blocked.

[0005] Therefore, it is necessary to propose a siphon type tree pit drainage device to solve the above problems. Utility Model Content

Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0031] See also Figure 3 , and combined with Figure 4As shown, a siphon type tree pit drainage device of the utility model is used to be installed in a flower bed 100, wherein the siphon type tree pit drainage device includes a concrete box 1 with an internal accommodating chamber 11, and the concrete box 1 can be a resin concrete box 1, and a crushed stone layer 6 or a gravel layer is buried on the outer edge surface of the concrete box, and a coarse sand layer is arranged around the crushed stone layer 6 or the gravel layer to filter the seepage water in the soil and achieve a primary filtration effect. The filtered water passes through a water hole provided on the upper part of the side wall of the concrete box 1 and enters the accommodating chamber 11.

[0032] like Figure 1 As shown, a grille net 2 is installed on the top of the concrete box 1 of the utility model, a carrying box 3 is installed in the accommodating cavity 11, a water permeable hole 31 is arranged on the top of the carrying box 3, a filter box 4 is installed on the upper part of the carrying box 3, the bottom of the filter box 4 is connected with the water permeable hole 31, and a water seepage hole 41 is arranged on the side wall of the filter box 4, filter bricks 42 are installed on both sides of the bottom of the filter box 4, and a filter body 43 is arranged between the filter bricks 42, a spoiler 44 is arranged on the top of the filter body 43, the spoiler 44 and the filter brick 42 are arranged at intervals, a water louver 45 is installed on the upper side wall of the filter box 4, a hanging basket 46 is hung on the grille, and the hanging basket 46 is located on the upper part of the spoiler 44; a siphon rainwater bucket 101 is arranged on the end face where the flower bed 100 is connected to the carrying box 3, and the siphon rainwater bucket 101 is connected with the water inlet of the rainwater collection pool 5 through a siphon pipe 103; the height difference between the siphon rainwater bucket 101 and the water inlet is greater than 4m.

Water louvers 45 are arranged around the hanging basket 46 to ensure that water in the surrounding soil can smoothly enter the device, and the water louvers 45 and the hanging basket 46 are regularly flushed; filter bricks 42 are arranged around the filter body 43 for fixing, and the flow rate is reduced by a spoiler 44, and the filter body 43 and the filter bricks 42 are used to achieve secondary fine filtration, and the filtered water is introduced into the rainwater collection pool 5 through the siphon rainwater bucket 101.

[0040] Compared with the prior art, the siphon type tree hole drainage device of the utility model solves the problem of silt blockage in the drainage device in the flower bed, and can effectively avoid the inconvenience of replacement due to damage to the device. At the same time, it solves the drainage flow rate problem, produces a higher drainage flow rate, and even plays a role in flushing the pipes. It also solves the problem of high sediment content in the drainage, which blocks the pipe network and rainwater wells.
