Description

Technical Field

[0001] The present application relates to the technical field of engineering construction, and in particular to a concrete drainage tool for use in narrow spaces. Background Art

[0002] During construction projects, narrow and long spaces can present challenges for concrete pouring, such as in the casting of side forms for municipal roads, curbstone backrests, and small traffic signal foundations. To ensure efficient pouring, the diameter of the pouring pipes is typically designed to be larger. This shortens the pouring time and prevents premature setting. However, using large-diameter pouring pipes in these narrow and long spaces not only fails to improve pouring efficiency, but also results in wasted concrete and requires additional cleaning steps. Summary of the Invention

[0003] The invention provides a concrete drainage tool for a narrow space, which can realize high-efficiency concrete pouring in a narrow and long construction space.

[0004] The technical solution of this application is as follows:

[0006] Furthermore, the drainage groove extends obliquely upward from the feed port toward the outer side of the bucket wall.

[0007] Furthermore, the bucket wall includes an upper bucket wall and a lower bucket wall, the diameter of the upper bucket wall remains unchanged, and the diameter of the lower bucket wall gradually decreases from top to bottom.

[0008] Furthermore, the feed port is arranged on one side of the upper bucket wall.

[0009] Furthermore, there are two connecting rods, one of which is arranged on the lower bucket wall on the same side of the feed port, and the other is arranged on the lower bucket wall on the other side symmetrical to the feed port.

[0010] Furthermore, a drainage pipe is connected to the lower end of the discharge port, and the drainage pipe is connected to the casting pipe through a connecting buckle.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows:

[0012] 1. This application enables precise concrete pouring in narrow spaces. The finished concrete is introduced into the receiving hopper through a drainage trough, and then connected to the pouring pipe through the discharge port to the pouring area. For narrow areas, continuous pouring can be achieved by using pulley travel, improving pouring efficiency.

[0013] 2. This application allows the support rod to be clamped in support grooves of different heights, and the angle of the support groove can be adjusted to adapt to different construction scenarios, thereby improving the convenience of pouring. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Based on the background technology, as shown in the attached Figure 1 and attached Figure 2 As shown, the present application provides a concrete drainage tool for a narrow space, including a receiving hopper 1, the receiving hopper 1 having a hopper wall 2 and a discharge port 3 formed by narrowing downward through the hopper wall 2, a feed port 4 being opened on at least one side of the hopper wall 2, the feed port 4 being provided with a drainage groove 5 extending toward the outside of the hopper wall 2, the hopper wall 2 being provided with support bars 6 attached to the hopper wall 2 at several heights below the feed port 4, and a support groove 7 being formed between two adjacent support bars 6, a supporting rod 8 being supported between the support groove 7 and the lower surface of the drainage groove 5; the hopper wall 2 below the feed port 4 is provided with a connecting rod 9, and the lower end of the connecting rod 9 is provided with a pulley 10.

[0020] In this embodiment, the drainage trough 5 is a trough-shaped structure with raised flanges on both sides to prevent concrete from spilling. The upper end of the support rod 8 is cut to accommodate the angle of the lower surface of the drainage trough 5. The drainage trough 5 can be hingedly connected to the bucket wall 2. When construction is complete, the drainage trough 5 can be rotated downward to be stored, helping to save space. The lower end of the support bar 6 is cut to form a pentagonal cross-section, which facilitates the arrangement of the support rod 8. It should be noted that multiple support rods 8 can be provided simultaneously.

[0021] As a preferred embodiment of the present application, the drainage groove 5 extends obliquely upward from the feed port 4 toward the outside of the bucket wall 2.

[0022] As a preferred embodiment of the application, the bucket wall 2 includes an upper bucket wall 2-12 and a lower bucket wall 2-22. The diameter of the upper bucket wall 2-12 remains unchanged, while the diameter of the lower bucket wall 2-22 gradually decreases from top to bottom. The upper bucket wall 2-12 maintains a constant diameter to expand the material receiving area, while the diameter of the lower bucket wall 2-22 gradually decreases to form a landslide, allowing concrete to flow into the drainage pipe 11.

[0023] In some specific examples of the above-mentioned implementation manner, the feed port 4 is arranged on one side of the upper bucket wall 2-12.

[0024] In a preferred embodiment of the above embodiment, there are two connecting rods 9, one of which is provided on the lower bucket wall 2-22 on the same side as the feed inlet 4, and the other is provided on the lower bucket wall 2-22 on the other side symmetrical to the feed inlet 4. The connecting rods 9 are supported on the lower bucket wall 2-22. Since the lower bucket wall 2-22 is inclined, the connecting rods 9 and the lower bucket wall 2-22 can form a more stable support on both sides, which not only helps to improve the supporting effect, but also can improve the strength of the lower bucket wall 2-22.

[0025] As a preferred embodiment of the present application, the lower end of the discharge port 3 is connected to a drainage pipe 11, and the drainage pipe 11 is connected to a pouring pipe 13 via a connecting buckle 12. By connecting the buckle 12 and the pouring pipe 13, refined pouring in narrow spaces can be achieved, the pouring quality can be improved, and various pouring scenarios can be adapted.

[0026] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0027] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
