DETAILED DESCRIPTION

[0027] The utility model makes further detailed description in combination with the drawings.

[0028] In combination with the drawings Figure 1 A bridge pile foundation construction safety protection device, including bottom plate 1, fence 2 and corner fence 3, bottom plate 1, fence 2 and corner fence 3 each are provided with eight, and all are right angle trapezoidal plate, bottom plate 1 is formed rectangular ring by mutual rotation, fence 2 is rotatably connected to be arranged on the outside of bottom plate 1, corner fence 3 is rotatably connected to be arranged on the edge of fence 2, adjacent corner fence 3 is rotatably connected to each other, bottom plate 1, fence 2 and corner fence 3 can be folded according to the rotating connection.

[0029] In combination with the drawings Figure 1 , the drawings Figure 3 , the drawings Figure 4 , the drawings Figure 5 , the drawings Figure 6 and the drawings Figure 7 , the right angle edge bottom of bottom plate 1 is equipped with hinge one 12, bottom edge top is equipped with hinge two 13, and the inclined edge top is equipped with hinge three 14, the bottom edge inner side of fence 2 is connected with hinge two 13, the inclined edge of fence 2 is equipped with sliding groove 8, sliding block 9 is arranged in sliding groove 8, and hinge four 15 is arranged on sliding block 9, the inclined edge of corner fence 3 is connected with hinge four 15, and the right angle edge is equipped with hinge five 16.

[0030] The folding mode of the device refers to the drawings Figure 8 , the drawings Figure 9 and the drawings Figure 10 , first, all fences 2 need to be folded inwards by hinge two 13, in the process, the inclined edges of adjacent fences 2 are close to each other, so that corner fence 3 is folded by hinge five 16, and sliding block 9 is decoupled from hinge four 15 at the inclined edge of corner fence 3 and fence 2 by sliding in sliding groove 8, until fence 2 completely overlaps bottom plate 1, and adjacent corner fences 3 overlap each other.

[0031] By lifting the right angle edge of bottom plate 1 upwards, adjacent right angle edges of bottom plate 1 can be rotated according to hinge one 12, and adjacent inclined edges of bottom plate 1 can be rotated according to hinge two 13, in the process, sliding block 9 continues to slide in sliding groove 8 to decouple hinge four 15 at the inclined edge of corner fence 3 and fence 2, and finally adjacent bottom plates 1 overlap each other to complete folding and recycling, and the bottom edge of bottom plate 1 is provided with handle 6, so that workers can hold handle 6 to lift the right angle edge of bottom plate 1 upwards.

[0032] Combined with appendix Figure 4 Appendix Figure 5 and attached Figure 6 The bottom edge of the base plate 1 is provided with a pin hole 5, and the outer side of the fence 2 is provided with a pin slide sleeve 10. The pin slide sleeve 10 is slidably provided with a pin 11. When this application is fully unfolded, the pin 11 can pass downward through the pin hole 5 and be driven into the soil.

[0033] Combined with appendix Figure 2 and attached Figure 5 The top of the right-angled side of the fence 2 is provided with a positioning plate groove 7, which can be used to fix the guide pipe positioning plate 4.

[0034] When deploying the safety protection device for bridge pile foundation construction, the folded device is first transported to the designated location on the construction site. The adjacent overlapping base plates 1 are then rotated and unfolded using hinges 12 and 13 to form a rectangular ring frame structure. During the unfolding of the base plates 1, the slider 9 slides within the groove 8, causing hinge 15 to adjust its position. This allows the corner fences 3 and 2 to gradually unfold into place as the base plates 1 unfold. Fence 2 is rotatably connected to the outside of the base plates 1, and corner fences 3 are rotatably connected to the edge of fence 2. Adjacent corner fences 3 are also rotatably connected to each other, thus constructing a complete safety protection area for bridge pile foundation construction.

[0035] The conduit positioning plate 4 of this device is installed on the fence 2 to position the conduit during construction, ensuring the accuracy and stability of the conduit installation. Pin holes 5 are distributed in appropriate positions on the base plate 1, fence 2, and corner fence 3. The insertion of pins 11 into the pin holes 5, along with the cooperation of pin sleeves 10, further secures the connections between the various parts of the device, enhancing its overall stability. Handles 6 are located in appropriate positions on the device, facilitating movement and repositioning by construction personnel. The positioning plate groove 7 is designed to hold small construction tools or accessories, improving the convenience and tidiness of the construction site.
