[0029] Please refer to Figure 1 The embodiment provides a rainwater drainage device for upper greening of basement roof, which comprises:
[0030] A water collecting well 1 is arranged on the basement roof 2 and located in the greening soil 3.
[0031] A drainage blind pipe 4 is embedded in the greening soil 3 around the water collecting well 1, and the drainage blind pipe 4 is used for guiding the infiltrated rainwater into the water collecting well 1.
[0032] A water collecting cylinder 5 is arranged in the water collecting well 1, and a plurality of water permeable holes 6 are formed in the water collecting cylinder 5 in the circumferential direction, the rainwater in the water collecting well 1 enters the water collecting cylinder 5 through the water permeable holes 6, and the water collecting cylinder 5 is also connected with the nearby rainwater well or drainage ditch through a plurality of drainage pipes 7.
[0033] A water pump 8 is arranged in the water collecting cylinder 5 and used for draining the collected rainwater in the water collecting cylinder 5 out through the drainage pipes 7.
[0034] The working principle of the rainwater drainage device for upper greening of basement roof provided by the embodiment is as follows:
[0035] The infiltrated rainwater in the greening soil 3 on the basement roof 2 is guided into the water collecting well 1 through the drainage blind pipe 4, then enters the water collecting cylinder 5 through the water permeable holes 6 on the water collecting cylinder 5, and then the collected rainwater in the water collecting cylinder 5 is drained out to the nearby rainwater well or drainage ditch through the drainage pipes 7 under the action of the water pump 8, the structure design can be used as a supplement and backup of the traditional plastic drainage board drainage mode, when the traditional drainage mode is blocked, the soil water can be drained in time under the action of the water pump 8, the vegetation growth is prevented from being damaged due to waterlogging, and the load of the basement roof 2 caused by the serious water accumulation of the greening soil 3 is prevented from increasing greatly.
[0036] In the embodiment, the water collecting well 1 is arranged on the basement roof 2, and a movable well lid 9 can be arranged at the bottom of the water collecting well 1, so that the maintenance and repair are facilitated. The basement roof 2 is covered with planting soil and greening plants, and the drainage blind pipe 4 is pre-embedded in the planting soil around the water collecting well 1.
[0037] In the embodiment, the water collecting cylinder 5 comprises a steel cage and a plurality of stainless steel plates. The steel cage is welded by a plurality of steel members. The outer wall and the bottom wall of the steel cage are covered by the stainless steel plates to form a cylindrical structure. The steel cage serves as the main support of the water collecting cylinder 5. The steel members can be angle steels or square steels. In order to receive the rainwater in the water collecting well 1, the outer wall and the bottom wall of the steel cage are sealed by the stainless steel plates to form a cylindrical structure with an upper opening.
[0038] Preferably, the outer wall of the water collecting cylinder 5 and the inner wall of the water collecting well 1 are filled with a filter layer 10. The filter layer 10 is used to filter the rainwater discharged from the drain blind pipe 4 to avoid clogging the water permeable holes 6. The filter layer 10 is also used to fill the gap between the water collecting cylinder 5 and the water collecting well 1 to prevent the gap from being occupied by soil so as to avoid affecting the rainwater to flow into the water collecting cylinder 5 through the water permeable holes 6.
[0039] In the embodiment, the filter layer 10 is composed of gravel and sand.
[0040] Preferably, a plurality of limiting rods 11 are horizontally arranged between the outer wall of the water collecting cylinder 5 and the inner wall of the water collecting well 1. The two ends of the limiting rod 11 abut against the outer wall of the water collecting cylinder 5 and the inner wall of the water collecting well 1, respectively. Since the water collecting cylinder 5 and the water collecting well 1 have a gap, the limiting rod 11 is arranged to limit the water collecting cylinder 5 to prevent the water collecting cylinder 5 from moving horizontally in the water collecting well 1.
[0041] More preferably, the limiting rod 11 is a telescopic rod. The telescopic rod can be adjusted in length according to the gap between the outer wall of the water collecting cylinder 5 and the inner wall of the water collecting well 1 to achieve better limiting effect. The structure of the telescopic rod is a known technology in the art. For example, the telescopic rod is composed of an inner tube and an outer tube. One end of the inner tube is inserted into the outer tube. The inner tube can move relative to the outer tube to achieve extension and shortening. The telescopic rod can be locked by a locking device such as a screw lock or a push button. The telescopic design of the telescopic rod is similar to that of a mop on the market. The present application does not limit the telescopic rod.
[0042] One limiting rod 11 or a plurality of limiting rods 11 can be arranged between each outer wall of the water collecting cylinder 5 and the corresponding inner wall of the water collecting well 1. The present application does not limit the number of the limiting rods 11.
[0043] In the embodiment, the rainwater in the water collecting well 1 flows into the water collecting cylinder 5 through the water permeable holes 6. The water permeable holes 6 are arranged near the bottom end of the water collecting cylinder 5. The height of the water permeable holes 6 should not be too high. The present application does not limit the specific height of the water permeable holes 6. As long as the rainwater in the water collecting well 1 can flow smoothly into the water collecting cylinder 5, the height of the water permeable holes 6 is acceptable.
[0044] Preferably, the water-permeable holes 6 are distributed equidistantly along the circumference of the water collecting cylinder 5. The equidistant distribution design can facilitate the water in the water collecting well 1 to enter from all around of the water collecting cylinder 5, and improve the rainwater removal efficiency. Of course, the number, size, shape of the water-permeable holes 6 and the interval between adjacent water-permeable holes 6 are not limited, and can be designed according to actual needs.
[0045] In this embodiment, the water-permeable holes 6 are covered with geotextile to ensure that the rainwater in the water collecting well 1 passes smoothly while preventing gravel and sand in the filter layer 10 from entering the water collecting cylinder 5 or clogging the water-permeable holes 6. In actual construction, the entire cylinder wall of the water collecting cylinder 5 can be covered to facilitate the fixation of the geotextile.
[0046] Preferably, the water pump 8 is a self-starting submersible pump which can start automatically according to the liquid level of the water collecting cylinder 5. By using the self-starting water pump 8, when the liquid level in the water collecting cylinder 5 is higher than the set value, the water pump 8 can start automatically and discharge the rainwater collected in the water collecting cylinder 5 to the nearby rainwater well or drainage ditch through the drain pipe 7, realizing the automation of rainwater removal. The self-starting submersible pump is a prior art, and the set value of the liquid level can be set artificially, and the specific structure thereof will not be described herein.
[0047] In this embodiment, two water pumps 8 are arranged in the water collecting cylinder 5, one for standby.
[0048] In summary, the rainwater removal device for basement roof upper greening provided by the embodiments of the present application can be used as a supplement and backup of the traditional plastic drainage board drainage method, and can timely remove soil water under the action of the water pump 8 when the traditional drainage method is blocked, so as to avoid damage to vegetation growth due to waterlogging and avoid a large increase in load of the basement roof 2 caused by serious water accumulation of the greening soil 3.
[0049] In addition, it should be recognized that, although the present application has been disclosed as above with preferred embodiments, the above embodiments are not intended to limit the present application. For any person skilled in the art, many possible changes and modifications or equivalent embodiments of the technical solutions of the present application can be made by using the disclosed technical contents without departing from the scope of the technical solutions of the present application.
