DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0018] Embodiment 1

[0019] A light safety protection device for bored cast-in-place piles, as Figure 1 and Figure 2As shown in the figure, it includes a mounting frame 1. There are four mounting frames 1. The adjacent upper and lower mounting frames 1 are rotatably connected. Connectors for easy splicing are connected to both the left and right sides of the upper mounting frame 1. A triangular rib plate for reinforcement is connected to the lower part of the lower mounting frame 1. Reflective sheets 2 are connected to both the left and right sides of the front of the mounting frame 1. Rotating doors 3 are rotatably connected to the mounting frames 1. First locking members 4 for locking the adjacent rotating doors 3 are provided on the mounting frames 1. Symmetric second locking members 5 are provided between the adjacent mounting frames 1. Protection mechanisms 6 are provided on the rotating doors 3.

[0020] The bored pile is a commonly used deep foundation construction technology, which is widely used in the construction of projects such as bridges, high-rise buildings, offshore platforms, port terminals, etc. A hole with a predetermined diameter is formed at a predetermined position through a drilling device. A steel reinforcement cage is placed in the hole as a reinforcement structure, and finally concrete is poured to form a pile body. When carrying out the bored pile operation, construction personnel need to fence and protect the construction site of the bored pile to prevent unauthorized personnel from entering by mistake. First, the mounting frame 1 is erected around the bored pile. Then, the upper mounting frame 1 is rotated so that the upper and lower mounting frames 1 form a vertical enclosure surface. Then, by rotating the second locking member 5, the upper and lower mounting frames 1 are fixedly locked. This foldable installation method makes the device more convenient during transportation and easy to disassemble after construction. The specifications of the bored pile usually need to be determined according to specific construction requirements. When it is necessary to fence and warn a larger bored pile construction site, splicing can be carried out through the connectors on the mounting frame 1 to meet the safety protection requirements of different sites. When the lighting conditions are poor, the reflective sheet 2 can play a role in warning unauthorized personnel. When construction personnel need to enter the interior of the construction site, the adjacent upper and lower first locking members 4 are toggled so that the rotating door 3 is disengaged from the locking state with the adjacent mounting frame 1. Construction personnel can enter the construction site by opening the upper and lower rotating doors 3, making it more convenient for construction personnel to enter and exit.

[0021] Embodiment 2

[0022] On the basis of Embodiment 1, as Figures 1 - 3 shown, the protection mechanism 6 includes dampers 62. Six dampers 62 are connected to each rotating door 3. Springs 63 are connected inside the dampers 62. Protection plates 61 are connected to the dampers 62. There are two specifications for the protection plates 61. The inner protection plates 61 are larger in size than the outer protection plates 61.

[0023] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, it further includes an anti-falling mechanism 7. The anti-falling mechanism includes an installation frame 71. Installation frames 71 are connected to the front and rear sides of the lower part of the lower installation frame 1. Conical blocks 72 are slidably connected to the installation frames 71. Adjusting members 73 are threadedly connected to the installation frames 71. The adjusting members 73 are connected to the adjacent conical blocks 72. Counterweight blocks 74 are arranged in the left and right interiors of the installation frames 71.

[0024] When the device is impacted by an external force, the protective plate 61 is squeezed. The adjacent dampers 62 and springs 63 can disperse the force on the protective plate 61, thereby reducing the degree of extrusion of the protective plate 61. To ensure the stability of the device, the adjusting member 73 can be rotated to make the conical block 72 slide downward. As the adjusting member 73 is continuously rotated, it gradually contacts the ground and inserts into the ground, which can prevent the device from tipping over to a certain extent, thereby enhancing the stability of the device.

[0025] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
