Description

Technical Field

[0001] The utility model relates to the technical field of safety fences, and particularly relates to a safety fence for a highway bridge pile foundation mud pool. Background Technique

[0002] The safety fence for a highway bridge pile foundation mud pool is a protective measure set to ensure the safety of construction personnel and the surrounding environment.

[0003] During the use of the existing safety fences for highway bridge pile foundation mud pools, as the underwater cast-in-place pile is a relatively common bridge pile foundation construction method, during the pile foundation drilling process, it is necessary to use mud to protect the hole wall, discharge slag, and clean the hole. The mud pools for pile foundation construction are usually arranged on the opposite side of the access road, and a mud pool (including a sedimentation tank and a slurry storage tank) is set for every 1 - 2 pier positions. The size of the mud pool and the slope ratio of the four surrounding slopes are studied and determined according to factors such as the pile diameter, hole depth, number of holes, and site, and anti-seepage measures are taken. The edge protection of the mud pool usually uses a customized grid safety guardrail. After the original ground is leveled, a concrete foundation is poured, and the base of the safety protection railing is connected to the concrete foundation through expansion bolts, which is relatively difficult to disassemble. Moreover, after the concrete base is used, it still needs to be broken, transported, and processed, which has a certain adverse impact on the environment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety fence for a highway bridge pile foundation mud pool to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A safety fence for a highway bridge pile foundation mud pool, including a fence base, and further including:

[0006] Fence fixing steel sheets arranged inside the fence base, base anchoring steel sheets arranged outside the fence base, steel pins arranged inside the base anchoring steel sheets, corner connection steel sheets arranged at one end of the fence base, fence corner bases arranged inside the corner connection steel sheets, grid fences arranged outside the fence fixing steel sheets, fence columns arranged on one side of the grid fences, and bolts arranged inside the fence base.

[0007] Preferably, the fence base is fixed on the fence column through the fence fixing steel sheets and bolts.

[0008] Preferably, the fence fixing steel sheet is a straight-folded angle steel sheet and is fixedly connected to the fence base through bolts.

[0009] Preferably, the base anchoring steel sheet is a straight-folded angle steel sheet and is fixedly connected to the fence base through bolts.

[0010] Preferably, the steel pin penetrates through the anchoring hole on the base anchoring steel sheet.

[0011] Preferably, the grid fence is fixed on the fence base through fence fixing steel sheets and bolts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, all component connections adopt bolt connections, and the tools used for installation and disassembly are simple, convenient and fast. The standard section of the 12# channel steel is 6m long, and non-standard section fence corner bases with a length of 2m can be added during actual construction to adjust the lengths of the long and short sides of the safety fence, with strong applicability; moreover, the 6m long standard section of channel steel weighs only 72.35kg, and 2 - 3 people can complete short-distance transportation. The installation and disassembly of the guardrail are convenient and fast; by using steel structure bases instead of concrete bases, the excavation of the construction foundation pit for the concrete base and the removal of solid waste are reduced. The steel shaving anchoring depth reaches 30 - 35cm, fully meeting the safety construction requirements under general climatic environment conditions. BRIEF DESCRIPTION OF THE DRAWINGS
