[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example:

[0030] like Figure 2 As shown, a rainwater hopper includes a rainwater hopper body 1 embedded in concrete 10. The rainwater hopper body 1 has a cylindrical structure, and its outer wall is attached to the concrete 10. A flow guide hood 2 is provided above the rainwater hopper body 1, and the flow guide hood 2 is fixedly connected to the rainwater hopper body 1. The bottom of the rainwater hopper body 1 is used to connect with a drainage pipe 5. This utility model has a simple structure. By attaching the outer wall of the rainwater hopper body to the concrete, the size of the rainwater hopper body is increased, thereby increasing the drainage capacity.

[0031] Before pouring, the reinforced concrete 10 of this utility model is positioned and pre-embedded for reliable fixation; during pouring, the concrete 10 and the rainwater hopper can fit tightly together.

[0032] A waterproof wing ring 4 is arranged around the outer periphery of the rainwater hopper body 1, and the waterproof wing ring 4 is embedded in the concrete 10. The present invention is ingeniously designed. The addition of a waterproof wing ring around the outer periphery of the rainwater hopper body strengthens the bonding surface and adhesion between the concrete slab and the rainwater hopper, and reduces the risk of water seepage at the joint between the concrete and the rainwater hopper.

[0033] The waterproof wing ring 4 is vertically arranged on the outer middle of the rainwater hopper body 1. The rainwater hopper body 1 and the waterproof wing ring 4 are fixedly connected and integrally formed; this improves the structural strength and stability of the rainwater hopper and further ensures safe use.

[0034] A waterproof rubber pad 6 is arranged below the rainwater hopper body 1; the waterproof rubber pad 6 is located at the joint of the concrete 10 and the rainwater hopper body 1, and the waterproof quality is further improved by adding the waterproof rubber pad 6; wherein the mortar coating layer 11 is located at the bottom of the concrete 10.

[0035] A metal pressing ring 8 is assembled on the waterproof rubber pad 6, the metal pressing ring 8, the waterproof rubber pad 6 and the rainwater hopper body 1 are connected through the fastening bolt 9; the waterproof rubber pad 6 is added at the joint of the bottom of the concrete 10 and the rainwater hopper body 1, the metal pressing ring 8 is used, and the fastening bolt 9 integrally formed with the rainwater hopper body 1 tightly presses the waterproof rubber pad 6 to the joint, so that the water seepage of the joint is effectively prevented.

[0036] A strip-shaped hole 20 is formed on the flow guide cover 2, and a plurality of strip-shaped holes 20 are distributed along the circumferential direction of the flow guide cover 2; the strip-shaped hole 20 on the flow guide cover 2 can straighten the rainwater, separate the air and water, and increase the drainage capacity.

[0037] A grating cover 3 is assembled on the flow guide cover 2, the flow guide cover 2, the grating cover 3 and the rainwater hopper body 1 are fastened through the bolt 7, and specifically, the grating cover 3 is made of stainless steel; the stainless steel grating cover 3 can intercept coarse impurities, especially leaves, plastic foam, paper shells, concrete stones and the like in the construction process; after delivery, leaves, plastic belts and the like impurities blown by wind in the distance can be intercepted in daily life, so as to create ideal water flow conditions for the flow guide cover 2. At the same time, the probability and risk of rainwater hopper and pipeline blockage are greatly reduced.

[0038] The flow guide cover 2 is mainly used for straightening the rainwater, separating the air and water, and also can intercept the impurities for the second time, so as to further reduce the risk of rainwater hopper body and pipeline blockage.

[0039] A waterproof layer 12 is pre-buried on the ground between the flow guide cover 2 and the rainwater hopper body 1, the waterproof layer is collected in the rainwater hopper, and is pressed tightly through the edge foot pressing ring of the flow guide cover, so that the waterproof layer 12 can be seamlessly spliced, and the rainwater cannot seep into the building layer on the concrete 10 board surface. The water seepage path is reduced to the greatest extent, so as to further reduce the water seepage risk.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application.
