[0025] Please refer to Figures 1-6 The concrete guardrail pouring guide device provided by the embodiments of the present application is applied to a guardrail pouring formwork 1, the top of the guardrail pouring formwork 1 is provided with a connecting piece 6 for connecting inner and outer formworks of the guardrail pouring formwork 1, and the guide device comprises: a guide cylinder 2, a first port of the guide cylinder 2 is used for adapting to a feeding port of the guardrail pouring formwork 1 of the concrete guardrail, and a second port of the guide cylinder 2 extends above the feeding port for feeding of concrete; wherein a slot 7 is arranged on the side of the guide cylinder 2 facing the guardrail pouring formwork 1, and along the width direction of the feeding port, the two sides of the slot 7 respectively penetrate two outer sides of the guide cylinder 2, and the slot 7 is adapted to the connecting piece 6; a recess 10 is arranged on the side of the connecting piece 6 facing the guardrail pouring formwork 1, and along the width direction of the feeding port, the two sides of the recess 10 respectively extend to the two outer sides of the guide cylinder 2; and a sealing door is arranged between any side edge of the recess 10 and the outer side of the guide cylinder 2 for sealing the opening of the side edge of the slot 7.

[0026] The concrete guardrail pouring guide device of the present application has many advantages in actual use. The ingenious design of the guide cylinder 2 can not only accurately guide the concrete into the guardrail pouring formwork 1, but also effectively prevent the concrete in the guardrail pouring formwork 1 from overflowing out of the feeding port during construction. This not only avoids the waste of concrete scattering, but also saves the tedious work of cleaning the construction site, greatly improving the construction efficiency. The design of the slot 7 and the connecting assembly makes the guide cylinder 2 firmly connected with the guardrail pouring formwork 1, ensuring the stability and reliability of the guide cylinder 2 during the concrete pouring process, thereby improving the pouring quality. The sealing door can seal the opening of the side edge of the slot 7, further preventing the concrete from overflowing, keeping the construction site clean, reducing the cleaning cost, and reducing the pollution risk to the surrounding environment.

[0027] Specifically, the outer side of the outer formwork of the guardrail pouring formwork 1 has a back lath 9, and the connecting piece 6 is connected with the back lath 9.

[0028] As a more preferred embodiment, the first port of the guide cylinder 2 extends into the feeding port;

[0029] The guide cylinder 2 above the feeding port is provided with a limiting piece 5 for lapping on the top of the guardrail pouring formwork 1.

[0030] In the above embodiment, first, the first port of the material guiding cylinder 2 extends into the feeding port, which can more accurately guide the concrete into the guardrail pouring formwork 1, reducing the splashing and overflowing of concrete during feeding, further avoiding material waste and pollution of the construction site. Secondly, the material guiding cylinder 2 above the feeding port is provided with a limiting piece 5 and overlaps the top of the guardrail pouring formwork 1, which makes the material guiding cylinder 2 more stable in position during use and less likely to shake or shift, ensuring the continuity and stability of concrete pouring. At the same time, the limiting piece 5 also facilitates the installation and disassembly of the material guiding cylinder 2, improving construction efficiency. Finally, this design improves the practicality and reliability of the concrete guardrail pouring material guiding device, providing better protection for concrete guardrail construction.

[0031] As a more preferred embodiment, the number of the above-mentioned insertion slots 7 and the number of the above-mentioned connecting assemblies are both two, and the two above-mentioned insertion slots 7 and the two above-mentioned connecting assemblies are one-to-one corresponding matching.

[0032] In the above embodiment, the setting of two insertion slots 7 and two connecting assemblies has many advantages. First, the corresponding matching of the two insertion slots 7 and the connecting assemblies increases the stability of the connection between the material guiding cylinder 2 and the guardrail pouring formwork 1. During concrete pouring, it can better withstand the pressure and impact force of the concrete, prevent the material guiding cylinder 2 from shifting or loosening, and ensure that the concrete can accurately flow into the guardrail pouring formwork 1. Secondly, the double connection design improves the reliability of the entire device, even if one of the connecting parts has a problem, the other connection can still play a certain supporting role, reducing the risk during construction. Furthermore, the two connecting assemblies can more evenly distribute the stress, allowing the material guiding cylinder 2 to remain balanced during operation, further improving the quality and efficiency of concrete pouring.

[0033] As a more preferred embodiment, the sealing door includes a sealing plate 4 and a guide rail, the sealing plate 4 is slidably arranged on the outer side of the material guiding cylinder 2, and the guide rail is arranged on the material guiding cylinder 2 and slidably matched with the sealing plate 4.

[0034] In the above embodiment, the sealing plate 4 is slidably arranged on the outer side of the material guiding cylinder 2, and the guide rail makes the sealing operation more convenient and efficient. When the side opening of the insertion slot 7 needs to be sealed, the sealing plate 4 can be quickly and accurately slid into position along the guide rail to achieve tight sealing. This design improves the reliability of the sealing, effectively preventing concrete from overflowing. At the same time, the sliding sealing door is more flexible in operation, making it easy for construction personnel to adjust and control according to actual conditions. The setting of the guide rail ensures the stability and linearity of the sliding of the sealing plate 4, ensuring the consistency of the sealing effect.

[0035] It is worth noting that the guide rail does not cover the opening on the side of the insertion slot 7 to avoid hindering the fit of the bearing piece 6 and the insertion slot 7, which is practical.

[0036] As a preferred embodiment, the sealing plate 4 is provided with a handle 8 away from the side of the material guiding cylinder 2.

[0037] In the above embodiment, the handle 8 provides a convenient gripping point for the operator to operate the sealing plate 4, making the opening and closing of the sealing plate 4 more effortless and rapid. During the construction process, when the opening on the side of the insertion slot 7 needs to be sealed or unsealed, the operator can quickly and accurately operate the sealing plate 4 through the handle 8, improving work efficiency.

[0038] As a preferred embodiment, the second port of the material guiding cylinder 2 is provided with a conical feeding hopper 3.

[0039] In the above embodiment, first, the conical feeding hopper 3 can expand the area of the feeding, making the concrete more smooth when feeding, reducing the risk of blockage during pouring. Second, the conical design helps to guide the flow of concrete into the material guiding cylinder 2, improving the efficiency and accuracy of feeding. Third, the conical feeding hopper 3 can act as a buffer to some extent, avoiding excessive impact on the material guiding cylinder 2 when pouring concrete.
