Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of anti-throwing type cast-in-place concrete guardrail integrated mobile construction trolley, belong to bridge construction technical field. BACKGROUND

[0002] In the construction process of concrete guardrail of bridge, highway etc., traditional technology generally uses the design mode that guardrail trolley is separated from anti-throwing and bottom protection device. When construction, first, the pouring position of guardrail is positioned by trolley, then bottom protection device is installed by artificial at the bottom of trolley to prevent concrete throwing.

[0003] However, such separated design leads to complicated construction process, low efficiency and significant safety hazard.

[0004] Specifically, the following three problems are shown:

[0005] 1. Process repetition and efficiency bottleneck: in the prior art, after completing a section of guardrail pouring, the bottom protection device needs to be removed first, then the trolley is moved to the next station, and then the protection device is reinstalled before the construction can continue. According to statistics, the time consumed for single process conversion is about 40-60 minutes, accounting for more than 20% of the overall construction period. Especially in the scene of large-span continuous construction, repeated disassembly and assembly cause serious delay of project progress, and construction cost increases significantly.

[0006] 2. High safety risk of aerial operation: the installation height of the bottom protection device is usually 3-5 meters from the ground, and the construction personnel need to climb to the operation surface after the trolley is moved to perform bolt fastening, steel plate splicing and other operations. Such high-altitude edge operation lacks a stable operation platform, and the concrete residue easily causes the surface of the trolley to be slippery. According to the industry statistics data in the past five years, the falling accidents caused by such process account for 68% of the total amount of guardrail construction accidents, which becomes a major safety hazard source.

[0007] 3. Lack of intelligentization of formwork system: the existing concrete guardrail formwork mostly uses split steel formwork, which needs 4-6 workers to complete the disassembly and assembly operation cooperatively. Manual knocking off formwork easily causes the formwork deformation rate to reach 15%-20%, and the average time consumed for single demolding is 2 hours / section. In addition, the traditional formwork lacks self-adaptive adjustment function, and when encountering curve section guardrail construction, special-shaped formwork needs to be customized and positioned repeatedly, which further reduces the construction efficiency.
