Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering protection, in particular to a safety protection fence used for bridge pile foundations. Background Art

[0002] Pile foundation construction generally uses impact drilling or rotary drilling. After the pile foundation drilling is completed, the hole is cleaned and inspected. During the operation, personnel are required to be close to the pile hole position; and after the pile foundation drilling is completed and the pile foundation is poured, it is inevitable that personnel and equipment will be evacuated to the next hole position for operation. The completed construction holes need to be based on the current relevant specifications and regulations, and effective safety measures are taken in combination with the actual situation of the project. For bored piles that do not need to be constructed temporarily or have completed construction, it is usually necessary to set up guardrails around the bored pile foundation to serve as a warning to construction personnel, thereby preventing them from falling into the bored piles.

[0003] The Chinese utility model patent (authorization announcement number: CN211736678U name: a kind of easily foldable building construction guardrail) includes two fixed rods and two groups of guard groups, the length direction of the fixed rod is perpendicular to the ground, the guard group includes two guard plates, the guard plates in one group of the guard groups are hingedly set on the same fixed rod, the guard plates in the guard group are hingedly set with the guard plates in the other guard group, and the two groups of guard groups form a circumferentially closed annular body, the fixed rod is provided with two limit plates, and the two limit plates are arranged at right angles on the fixed rod, the guard group is located on the inner side of the right-angle cavity formed by the two limit plates, the near-ground end of the limit plate is provided with a contact plate that fits the ground, and the contact plate is threaded with anchor bolts. The utility model has the effect of conveniently folding the guardrail, but the above technology has a disadvantage that the pile hole is not protected, and there are still safety hazards during and after the construction of the pile foundation construction site.

[0027] like Figure 1 , 3 As shown in Figures 4 and 5, a safety protection fence for bridge pile foundations includes a grating plate 1, and movable guardrails 2 are hinged on the left and right sides of the grating plate 1. The two movable guardrails 2 are connected by a fixed guardrail 3. The fixed guardrail 3 is composed of two pieces. The two fixed guardrails 3 can be detachably installed on both sides of the movable guardrail 2. The movable guardrail 2 and the fixed guardrail 3 are composed of multiple pieces. The adjacent two pieces of the movable guardrail 2 and the adjacent two pieces of the fixed guardrail 3 are connected by bolts 4. The movable guardrail 2 and the fixed guardrail 3 can be designed in a standardized manner. According to the different sizes of the covered openings, the grating plates 1 of corresponding sizes are selected and then spliced. The movable guardrail 2 and the fixed guardrail 3 are finally installed on the grating plate 1. There is no need to make multiple sets of fences, which reduces the cost of using the fences. The grating plate 1 covers the opening of the pile foundation hole to avoid the risk of people falling into the opening of the pile foundation. At the same time, when personnel need to inspect the hole, the fixed guardrail 3 on one side can be removed to allow personnel to enter the fence to work, while the other three sides are still erected on the grating plate 1 to warn peripheral personnel, ensuring the safety of on-site construction operations, solving the potential safety hazards during and after pile foundation construction, and facilitating promotion and use.

[0028] In this embodiment, if Figure 1 and 2 As shown, the distance between the two movable guardrails 2 folded on the grating plate 1 is not less than 0.3m. When the pile foundation is hoisted into the pile foundation hole, the fixed guardrail 3 is first removed, and then the movable guardrail 2 is folded to prevent the surrounding personnel from falling into the pile foundation hole. When hoisting and aligning, a steel ladder is placed on the grating plate 1 between the two movable guardrails 2. The personnel stand at both ends of the steel ladder and hold the pile foundation for comparison. Then, when the pile foundation is slowly lowered to the hole mouth, the steel ladder and the grating plate 1 are pulled out, and then the pile foundation is placed into the pile foundation hole.

[0029] In this embodiment, if Figure 1 , 3As shown in Figures 4 and 6, a positioning rod 5 is fixed on the moving guardrail 2. There are two positioning rods 5 and they are respectively located at the two ends of the moving guardrail 2. The positioning rods 5 extend along the height direction of the moving guardrail 2. Sleeves 6 are fixed at both ends of the fixed guardrail 3. The two moving guardrails 2 are fixed by inserting the positioning rods 5 into the corresponding sleeves 6. The structure is simple and easy to disassemble and assemble.

[0030] In this embodiment, if Figure 1 As shown, both the moving guardrail 2 and the fixed guardrail 3 are coated with self-luminous paint, making them more eye-catching at night, improving the attention of personnel and increasing their protective safety.

[0031] In this embodiment, if Figure 1 , 3 As shown in FIGS. 4 and 6 , a pin hole is provided on the sleeve 6 and passes through the positioning rod 5 . A pin 7 is inserted into the pin hole to increase the stability of the fixed railing 3 and prevent it from being accidentally removed.

[0032] In this embodiment, if Figure 3 and 4 As shown, a pulling ring 8 is installed on the pin 7, and the pulling ring 8 is far away from the insertion end of the pin 7, so as to facilitate the pulling out of the pin 7.

[0033] In this embodiment, if Figure 6 As shown, the pin hole extends into the moving guardrail 2, and the pin 7 is inserted into the moving guardrail 2 through the sleeve 6. The positioning rod 5 is connected to the moving guardrail 2 through the pin 7, which increases the structural stability of the positioning rod 5 and enhances the tensile strength of the positioning rod 5.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
