Description

Technical Field

[0001] This utility model relates to the technical field of guardrail construction, and in particular to a simple device for filling soil between guardrails. Background Technology

[0002] Highway median strips typically use precast concrete guardrails on both sides. After the precast guardrails are installed, soil is filled between the two concrete guardrails. Traditionally, the soil filling method involves manual labor combined with loaders to directly backfill the soil between the guardrails. During backfilling, a large amount of soil is spilled, which pollutes the road surface and generates dust, increasing workload and consuming materials, manpower, and time.

[0003] To address the aforementioned issues, Chinese Utility Model Patent Application No. CN202020965796.5 discloses a central median barrier backfilling guide device. Its key features are: it consists of a fixed frame, a hopper, traveling wheels, and guide wheels. The hopper, traveling wheels, and guide wheels are all fixed to the fixed frame. The hopper is a funnel-shaped hopper, wider at the top and narrower at the bottom, with the width of the lower outlet not exceeding the distance between two barriers. The fixed frame is composed of rods with four downward-extending legs at the four corners. The axle centerline of the traveling wheels is parallel to the ground and fixed below the front and rear rods of the fixed frame. The guide wheels are located inside the four legs, with their axle centerlines perpendicular to the ground. The distance between two opposing guide wheels in the width direction is greater than or equal to the distance between the outer surfaces of the two barriers. This utility model is easy to move and operate, allowing for rapid backfilling during construction, ensuring the road surface is not contaminated by soil sources, and preventing damage to the central median concrete from direct backfilling by loaders. It protects the concrete barriers while also improving the finished product's appearance quality.

[0004] Although the above solution solves the problem of soil spillage, the soil is guided by a hopper, which has a small construction range, low efficiency, and poor adjustability. Utility Model Content

[0031] like Figures 1-3 As shown, this utility model discloses a simple device for filling soil between guardrails, including multiple simple units connected end to end. Each simple unit includes a base 1, a side mold 2, and a bottom pulley 3. The base 1 is used to be erected on the top surface of two guardrails 4, and the base 1 has a filling space that communicates with the passage between the guardrails 4. The base 1 includes four bottom rods 1.1, which are connected end to end to form the base 1. The four bottom rods 1.1 enclose the space to form a filling space that communicates with the passage between the guardrails 4. In this embodiment, the base 1 is a rectangular frame structure.

[0032] Side molds 2 are installed in pairs on the base 1 along the length of the base 1. The two side molds 2 are gradually inclined from bottom to top towards opposite sides, and a guiding space for filling is formed between the two side molds 2. The opening formed at the lower end of the two side molds 2 is located in the passage area between the four guardrails and the size is less than or equal to the size of the passage between the four guardrails, so as to facilitate the complete filling of the four guardrails into the passage between the four guardrails.

[0033] Bottom pulleys 3 are installed in pairs at the bottom of the base 1. Each pair of bottom pulleys 3 is supported on the top surface of the two guardrails 4 and can slide along the guardrails 4.

[0034] When in use, a loader is used directly for backfilling. The backfill is restrained and guided by the guide space formed by the two side molds 2, which are larger at the top and smaller at the bottom. This increases the soil-receiving area between the guardrails 4, improves construction efficiency, prevents backfill from spilling onto the road surface, reduces dust, and ensures green construction. In addition, by setting up multiple simple units, the number of simple units can be selected according to the project progress, increasing the construction range and further improving construction efficiency. Moreover, in terms of installation and dismantling, it is convenient for individual and joint use.

[0035] Side rods 5 with the same slope as the side mold 2 are installed at both ends of the bottom rod 1.1 along its length. The side rods 5 are located outside the side mold 2, and the side mold 2 is connected to the side rods 5. The side mold 2 is fixed by the side rods 5, which improves stability.

[0036] A top rod 6 is connected to the upper end of the side rod 5 on the same side as the side mold 2. A horizontal rod 7 spanning the two side molds 2 is connected between the top rods 6. A support rod 8 is installed between the side rod 5 and the bottom rod 1.1. The support rod 8 is preferably set vertically to support the side mold 2. The above arrangement further improves the stability of the frame structure and avoids damage to the device caused by the impact force during backfilling.

[0037] A connecting component 9 located on the outer side of the guardrail 4 is installed at the end of the bottom bar 1.1, which is set along the width direction of the guardrail 4. The connecting component 9 is provided with a side pulley 10 that abuts against the outer side of the guardrail 4. The side pulley 10 can slide along the guardrail 4. The connecting component 9 includes an extension bar, an upper inclined bar, and a lower inclined bar connected together in sequence. One end of the extension bar is connected to the bottom bar 1.1, and the other end is connected to the upper inclined bar. The upper inclined bar gradually tilts from top to bottom toward the side away from the guardrail 4, and the lower inclined bar gradually tilts from top to bottom toward the side closer to the guardrail 4. The side pulley 10 is installed at the end of the lower inclined bar.

[0038] A steel pipe 11 is coaxially mounted on the side rods 5 at both ends of the length of the simplified unit. The steel pipes 11 on adjacent simplified units are coaxially mounted vertically, and adjacent simplified units are connected by insert rods 12 inserted inside the steel pipes 11. Through the above connection, multiple units can be connected, and when facing the curved guardrail 4, the simplified unit can be set in an arc shape by connecting the insert rod 12 on one side, which is convenient to adapt to various changes of the guardrail 4.

[0039] Among them, the pulleys in the above-mentioned device can be swivel wheels.

[0040] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
