Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction engineering maintenance, and in particular relates to a sandbag for maintaining bridge deck guardrails. Background Art
[0002] After the construction of the high-speed railway bridge deck is completed, the guardrail needs to be maintained regularly. If the maintenance is not timely, the concrete surface is prone to cracking, which not only affects the appearance quality of the concrete, but may also reduce its structural strength and durability, and reduce the quality and durability of the concrete.
[0003] At present, the commonly used maintenance measures for bridge deck guardrails are: using "U"-shaped steel bar clamps (spacing 2m) to clamp composite geotextiles. To prevent the geotextile from floating, sandbags are used to press the bottom of the geotextile, and water is manually sprinkled with a sprinkler truck, resulting in a large amount of labor, machinery and material costs. Utility Model Content
[0004] The purpose of the utility model is to provide a sandbag for maintaining bridge deck guardrails, so as to improve the maintenance efficiency of the bridge deck protection wall and reduce the maintenance cost.
[0005] The present invention adopts the following technical solutions to achieve the above-mentioned purpose:
[0006] A wind and sandproof bag for maintaining bridge guardrails. After absorbing water, the wind and sandproof bag can rely on its own gravity to cover the outer surface of the concrete guardrail; the wind and sandproof bag has two layers of geotextile, upper and lower; a plurality of water-absorbing and weight-increasing strips are arranged between the two layers of the geotextile; the plurality of water-absorbing and weight-increasing strips are arranged horizontally, and there is a spacing between each two adjacent water-absorbing and weight-increasing strips; a longitudinal soft water pipe is also arranged between the two layers of the geotextile; water spray holes are spaced apart on the longitudinal soft water pipe; and quick connectors for quick connection with other wind and sandproof bags are respectively provided at both ends of the longitudinal soft water pipe.
[0007] The width of the water-absorbing and weight-increasing strip is 3 cm.
[0008] The water inlet of the longitudinal soft water pipe can be connected to an automatic water supply device.
[0009] The automatic water supply device includes a water tank, a water pump and a controller. The water inlet end of the water pump is connected to the water tank through a pipeline, the water outlet end of the water pump is connected to the water inlet of the above-mentioned longitudinal soft water pipe through a pipeline, and the water pump is connected to the power supply through the controller.
[0010] A horizontal water supply pipe is provided between the two layers of geotextiles to connect with other wind and sand bags to form modular wind and sand bags, which can be applied to large-area covering and maintenance projects.
[0011] The utility model proposes a wind and sandproof bag for maintaining bridge guardrails. By adopting the above-mentioned technical solution, the maintenance cost can be effectively reduced, which helps to improve the overall maintenance effect of the bridge guardrails and meet the efficient maintenance needs of concrete guardrails.

[0014] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:
[0015] like Figure 1 As shown, a wind and sand bag for maintaining bridge guardrails can be covered on the outer surface of the concrete guardrail by its own gravity after absorbing water; the wind and sand bag has two layers of geotextile 1, upper and lower; a plurality of water-absorbing and weight-increasing strips 2 are arranged between the two layers of geotextile 1; the width of the water-absorbing and weight-increasing strips is 3 cm; the plurality of water-absorbing and weight-increasing strips 2 are arranged horizontally, and there is a spacing between each two adjacent water-absorbing and weight-increasing strips 2; a longitudinal soft water pipe 3 is also arranged between the two layers of geotextile; water spray holes 4 are spaced apart on the longitudinal soft water pipe 3; both ends of the longitudinal soft water pipe 3 and the transverse soft water pipe 5 are respectively provided with quick connectors 6 for quick connection with other wind and sand bags.
[0016] The water inlet of the longitudinal soft water pipe can be connected to an automatic water supply device (not shown in the figure).
[0017] The automatic water supply device includes a water tank, a water pump and a controller. The water inlet end of the water pump is connected to the water tank through a pipeline, the water outlet end of the water pump is connected to the water inlet of the above-mentioned longitudinal soft water pipe through a pipeline, and the water pump is connected to the power supply through the controller.
[0018] A transverse water supply pipe 5 is provided between the two layers of geotextiles to connect with other wind and sand bags to form modular wind and sand bags, which can be applied to large-area covering and maintenance projects.
[0019] This utility model proposes a sandbag for maintaining bridge guardrails. With its quick-connect design, the sandbag can be assembled to the desired length based on the guardrail's length, and the bag wraps around the concrete guardrail under its own gravity. The water pump's inlet is connected to a reservoir via a pipeline, while its outlet is also connected to a longitudinal soft water pipe. The pump is connected to a power source via a controller that can set water supply and stop times based on temperature, minimizing water waste. This utility model features a simple structure, easy assembly and disassembly, and is labor-saving.
