As shown in fig. 1, the rainwater overflow device of the embodiment of the invention comprises a rainwater well 1, a water inlet pipe 2 and a water outlet pipe 4, wherein the rainwater well 1 is buried under the ground, one side of the rainwater well 1 is provided with a water inlet, one side far away from the water inlet is provided with a water outlet, the top of the rainwater well 1 is provided with a cover plate 7, the water inlet pipe 2 is arranged at one side of the rainwater well 1 provided with the water inlet, one end of the water inlet pipe is connected with the water inlet of the rainwater well 1, the other end of the water inlet pipe is connected with a rainwater storage pool, the water outlet pipe 4 is arranged at one side of the rainwater well 1 provided with the water outlet, one end of the water outlet pipe is connected with the water outlet of the rainwater well 1, and the other end of the water outlet pipe is connected with a municipal rainwater pipe network system. The catch basin 1 may be square, circular or rectangular in shape, and may be constructed using bricks or concrete. In the present embodiment, the catch basin 1 has a rectangular shape. The cover plate 7 and the side wall of the catch basin 1 are both constructed by reinforced concrete.

Preferably, the bottom of the rainwater well 1 is provided with an overflow weir 5, the overflow weir 5 is connected with two side walls of the rainwater well 1 which are not provided with a water inlet and a water outlet, a gap is arranged between the top of the overflow weir 5 and the rainwater well cover plate 7, and the height of the overflow weir 5 is the designed liquid level of the storage tank. The rainwater regulation pond that comes is reformed transform by natural pool, when outlet pipe 4 buries deeply, rainwater among the rainwater regulation pond gets into inlet tube 2 and reachs rainwater well 1, because the position of outlet pipe 4 is nearer apart from rainwater well 1 bottom, the rainwater flows away through outlet pipe 4 very easily to lead to the rainwater regulation pond water level to hang down excessively, can't play the effect of water landscape. When the water outlet pipe 4 is buried too shallow, the soil covering of the pipeline is insufficient, so that the pipeline is easy to break by rolling of an automobile, and the conditions of freezing, swelling, cracking and the like can occur when extreme weather is met. In this embodiment, in order to avoid hidden troubles caused by too deep or too shallow burying of the water outlet pipe 4, the overflow weir 5 is arranged at the bottom of the rainwater well 1, and the overflow weir 5 is arranged between two side walls of the rainwater well 1 without a water inlet and a water outlet. The overflow weir 5 can prevent rainwater from flowing into the water outlet pipe 4, and the water level of the water landscape is ensured. Meanwhile, a gap is arranged between the top of the overflow weir 5 and the rainwater well cover plate 7, and the water passing capacity is ensured by the gap. When the water level reaches the design liquid level, namely when the water level exceeds the height of the overflow weir 5, rainwater flows over the overflow weir 5, flows into the water outlet pipe 4 and is discharged to the municipal rainwater pipe network system. The overflow weir 5 has two shapes of a straight shape and a tooth shape. In the present embodiment, the overflow weir 5 is a reinforced concrete straight weir. As shown in fig. 2, the straight weir divides the rectangular rainwater well 1 into a front well chamber 14 and a rear well chamber 15, the front well chamber 14 is connected with the water inlet pipe 2, and the rear well chamber 15 is connected with the water outlet pipe 4. When the water level in the rainwater storage tank is lower than the designed liquid level, namely the water level is lower than the height of the overflow weir 5, the overflow weir 5 blocks rainwater, the water does not enter the rear well chamber 15, and the water level of the front well chamber 14 is flush with the water level of the rainwater storage tank; when the water level in the rainwater storage tank is higher than the designed liquid level, namely the water level is higher than the height of the overflow weir 5, rainwater overflows from the upper part of the overflow weir 5, flows into the back well chamber 15 and then enters the municipal rainwater pipe network system.

Preferably, the connecting end of the water inlet pipe 2 and the rainwater storage tank is bent downwards to remove large suspended matters in water. Due to natural reasons or artificial reasons, large suspended matters 11 can float in the waterscape at times, and the large suspended matters 11 can easily enter the water inlet pipe 2 along with the flowing of rainwater to block an overflow pipeline. Bend is downwards arranged at the connecting end of the water inlet pipe 2 and the rainwater storage tank, so that the large suspended matters 11 can be prevented from entering the pipeline. The bending angle is not limited, and the direction is downward. In this embodiment, inlet tube 2 sets up a perpendicular decurrent 90 elbow 3 with the link of rainwater regulation pond, and the material and the nominal diameter of elbow are the same with inlet tube 2 for avoid bold suspended solid 11 to get into the pipeline and block up the pipeline.

Preferably, rainwater well apron 7 is equipped with two well heads, and two well heads are located the overflow weir both sides respectively, and two well head tops are equipped with pit shaft 8 respectively, and the pit shaft top is equipped with well

lid

9, 13 parallel and level of terrace on well lid 9 and rainwater regulation pond bank. Because there is silt to pile up usually in catch basin 1, influence overflow effect for avoiding the pipeline to block up, need regularly clear to catch up maintenance to catch basin 1 and pipeline usually. In this embodiment, overflow weir 5 has divided into 15 two parts in preceding room 14 of well and the well rear room with rainwater well 1, for the convenience of the personnel clearly draw the maintenance, corresponds respectively in the preceding room 14 of well of rainwater well 1 and well rear room 15 top and is equipped with the well head, and the well head top sets up

concrete shaft

8, and 8 tops of pit shaft set up well lid support 10, and well lid support 10 top sets up well lid 9, well

lid

9 and 13 parallel and level of terrace. When the manhole cover 9 is opened for regular cleaning, the rainwater well 1 can be accessed for operation. Because the well heads are respectively arranged in the front well chamber 14 and the rear well chamber 15, the front well chamber 14 and the rear well chamber 15 can be respectively cleaned and overhauled according to conditions.

Preferably, as shown in fig. 3, a ladder stand 6 is provided on an inner sidewall of the rainwater well 1. In order to facilitate the cleaning and maintenance of personnel, a ladder stand 6 can be arranged on the side wall inside the rainwater well 1. In this embodiment, since the overflow weir 5 divides the rainwater well 1 into the front well chamber 14 and the rear well chamber 15, the climbing ladder 6 is respectively disposed on the side walls of the front well chamber 14 and the rear well chamber 15, the climbing ladder 6 is disposed on the side wall of the rainwater well 1 near the shaft 8, and the climbing ladder 6 needs to be firmly connected with the side wall of the rainwater well 1. The material and the concrete specification of cat ladder 6 do not do the restriction, as long as satisfy the climbing demand can. In this embodiment, a metal ladder is used.

In this embodiment, the connection end of inlet tube 2 and rainwater regulation pond can get rid of the bold suspended solid 11 in aquatic through setting up perpendicular decurrent 90 elbow 3 to prevent causing pipe blockage. The overflow weir 5 is arranged at the bottom of the catch basin 1, so that the water level height of a waterscape can be ensured, meanwhile, the water outlet pipe 4 can be deeply buried, the potential safety hazard caused by too shallow buried depth is avoided, and the defects of the prior art are overcome. Since the sludge in the rainwater well 1 needs to be cleaned manually, the cleaning and maintenance by the personnel can be facilitated by arranging the well shaft 8 corresponding to the front well chamber 14 and the rear well chamber 15 respectively.
