[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete rainwater inlet mold, comprising an inner mold and an outer mold, wherein the outer mold is surrounded by several side plates, and the outer mold is provided with an opening for inserting the inner mold, wherein the side plates are provided with protruding posts, and the inner mold is inserted into the opening and abuts against the protruding posts; a gap is provided between the inner mold and the outer mold, and the inner mold and the outer mold cooperate with the gap between them to form a cavity, and the opening is also used for grouting into the cavity.

[0005] As a further improvement of this utility model, one or more side plates are provided with protruding posts.

[0006] As a further improvement of this utility model, a chamfer is provided on the side of the protruding post away from the side plate.

[0007] As a further improvement of this utility model, the chamfer extends to the side plate.

[0008] As a further improvement of this utility model, the side plates are detachably connected or the side plates are integrally formed.

[0009] As a further improvement of this utility model, the inner mold is configured as a hollow columnar shape.

[0010] As a further improvement of this utility model, the inner mold is provided with reinforcing ribs, which can reinforce the outer mold.

[0011] The beneficial effects of this utility model are that by using the gap between the outer mold and the inner mold to form a cavity, the precision of the manufacturing process is improved, the cost is reduced, and the mold can be used to better process the rainwater well.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] A precast concrete rainwater inlet mold includes an inner mold 1 and an outer mold 2. The outer mold 2 is surrounded by several side plates 3. The outer mold 2 is provided with an opening 4 for the inner mold 1 to be inserted. The side plates 3 are provided with protruding posts 5. The inner mold 1 is inserted into the opening 4 and abuts against the protruding posts 5. A gap is provided between the inner mold 1 and the outer mold 2. The inner mold 1 and the outer mold 2 cooperate with the gap between them to form a cavity. The opening 4 is also used to inject grout into the cavity.

[0016] like Figure 1 As shown, in this embodiment, the inner mold 1 is inserted into the opening 4 and abuts against the protrusion 5. The protrusion 5 can clamp the inner mold 1 and limit its position. This setting can reduce the difficulty of operation. In addition to allowing the inner mold 1 to be inserted, the opening 4 is also used to inject grout into the cavity. There is no need to set another channel, which reduces the cost. Grout can also directly enter the cavity from the opening 4, and the grouting is smooth.

[0017] Preferably, one or more side plates 3 are provided with protruding posts 5.

[0018] like Figure 2 As shown, in this embodiment, the number of side plates 3 and protrusions 5 can be set according to requirements, increasing the diversity of the mold; further optionally, the number of side plates 3 and protrusions 5 is not fixed, and the number of side plates 3 and protrusions 5 can be increased or decreased.

[0019] Preferably, the side of the protruding post 5 away from the side plate 3 is provided with a chamfer 6.

[0020] like Figures 1 to 2 As shown, in this embodiment, the chamfer 6 facilitates the insertion of the inner mold 1 and optimizes the grouting effect.

[0021] Furthermore, chamfer 6 extends onto side panel 3.

[0022] In this embodiment, the chamfer 6 extends to the side plate 3, which facilitates pipe installation after demolding of the rainwater inlet well.

[0023] Preferably, the side panels 3 are detachably connected or the side panels 3 are integrally formed.

[0024] In this embodiment, different connection methods for the side plates 3 can be selected according to the site conditions. The advantages of detachable connection are that it is convenient to carry, simple to maintain later, and low replacement cost; the one-piece molded structure has higher strength and better sealing between the side plates 3.

[0025] Furthermore, the inner mold 1 is set as a hollow columnar shape.

[0026] In this embodiment, the hollow columnar shape can reduce the cost and weight of the inner mold 1.

[0027] Preferably, the inner mold 1 is provided with reinforcing ribs 7, which can reinforce the outer mold 2.

[0028] In this embodiment, the reinforcing rib 7 can enhance the structural strength of the inner mold 1; and the position of the reinforcing rib 7 is convenient for the operator to lift, so that the operator can insert the inner mold 1 into the outer mold 2 or pull the inner mold 1 out of the outer mold 2.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
