The structure of this embodiment is simple and can be installed quickly. It not only provides a pulling effect when the pipe 4 accidentally falls off, but also avoids defects in the support structure or pipe 4 caused by welding.

[0029] In this embodiment, the connecting part 3 further includes a first connecting member 32, which is connected to the connecting body 31, and the lifting lug 2 is inserted into the first connecting member 32. Preferably, the first connecting member 32 is a U-shaped part, and its opening width is adapted to the lifting lug 2.

[0030] In this embodiment, each pipe clamp 1 includes a clamping body 11, and a wing plate 12 is provided at the end of the clamping body 11. Adjacent clamping bodies 11 are connected by the wing plates 12, and a connecting body 31 is connected to the corresponding wing plate 12.

[0031] In this embodiment, the connecting part 3 further includes a second connecting member 33, which is connected to the connecting body 31 and is clamped between the two wing plates 12.

[0032] In this embodiment, bolt holes are provided on the wing plate 12, and the pipe clamping part also includes multiple bolt assemblies 13 for connecting adjacent wing plates 12. The second connector 33 has connecting holes, which correspond to the bolt holes for installing the bolt assemblies 13. Preferably, the number of bolt holes on the wing plate 12 for clamping the second connector 33 is not less than the number of connecting holes on the corresponding second connector 33. In this embodiment, the number of bolt holes on the wing plate 12 for clamping the second connector 33 is greater than the number of connecting holes on the corresponding second connector 33. Multiple pipe clamps 1 can be pre-tightened through some of the bolt holes to fit over the pipe 4, and then the remaining bolt holes are used to correspond to the connecting holes of the second connector 33 to achieve the connection between the second connector 33 and the pipe clamp 1. In this embodiment, multiple bolt holes can be partially used for pre-tightening the pipe 4 and partially used for connecting with the second connector 33, making the installation method flexible, convenient to operate, and improving construction efficiency.

[0033] In this embodiment, the pipe clamp 1 is provided with an arc-shaped contact surface, which is adapted to the outer diameter of the pipe 4. Preferably, the arc-shaped contact surface is provided on the clamping body 11, which better ensures the stability of the connection with the pipe 4, reduces external damage to the pipe 4, and better ensures the reuse of the pipe 4 after disassembly. Preferably, the clamping body 11 and the wing plate 12 are integrally formed, which can improve the safety and stability during use. The pipe clamp 1 is made of flat steel, the middle part is processed into a semi-circle, and the two ends are respectively provided with wing plates 12 with holes, and the structure of the two wing plates 12 can be made into the same structure or different structures according to the requirements. The radial cross-sectional curvature of the clamping body 11 matches the outer diameter of the pipe 4. This embodiment can ensure the constraint effect on the pipe 4, while ensuring the appearance quality of the pipe 4.

[0034] In this embodiment, the length of the connecting body 31 is adjustable. The connecting body 31 includes an adjusting tube 311 and threaded adjusting rods 312 disposed at both ends of the adjusting tube 311. The two threaded adjusting rods 312 rotate in opposite directions and are threadedly connected to the adjusting tube 311 respectively.

[0035] In this embodiment, the lifting lug 2 can be selected according to the construction requirements to find a suitable size, and anti-slip texture can also be set in the groove 21 of the lifting lug to improve the fixing strength.

[0036] On the other hand, this utility model also provides a deep foundation pit support system, including the above-mentioned fall protection safety device, and its construction steps are as follows:

[0037] A support structure is laid out around the perimeter of the foundation pit, through which the pipe body can be erected. Preferably, Larssen interlocking steel sheet piles 5 are laid out along the foundation pit to form a support structure. Bearing brackets 6 and supporting walers 7 are installed at the predetermined elevation of the steel sheet piles 5, and the pipe body 4 is erected. The pipe body 4 used for support is arranged laterally and its axis is orthogonal to the excavation surface of the foundation pit. Steel sheet piles 5 are symmetrically provided at both ends of the pipe body 4.

[0038] The pipe body 4 and the support structure are connected to the fall arrestor using a weld-free method. Preferably, both ends of the pipe body 4 are connected to the support structure via the fall arrestor. During installation of the fall arrestor, a predetermined mark can be drawn at a distance from the end of the pipe body 4. The pipe clamp 1 is then installed at the corresponding position and pre-tightened with a matching number of bolt assemblies 13. Multiple pipe clamps 1 are interconnected to fit over the outside of the pipe body 4. In this embodiment, a curved surface design adapted to the outside of the pipe body 4 can be used to cover the outside of the pipe body 4 with multiple pipe clamps 1. The second connector 33 is inserted between the corresponding two wing plates 12 and connected via the remaining bolt assemblies 13. The lifting lug 2 is detachably connected to the support structure. In this embodiment, the lifting lug 2 can be engaged with the corresponding sheet pile 5 via the lifting lug slot 21 and hung on the corresponding sheet pile 5. Adjust the length of the connecting body 31 so that the pipe clamp 1, the connecting part 3, and the lifting lug 2 are connected to each other and kept in a pre-tightened state. This ensures that the fall protection safety device is in a non-stressed pre-tensioned state, so as to avoid long-term stress affecting the service life of the fall protection safety device and to ensure the protective effect when the pipe body 4 falls off accidentally.

[0039] When pipe body 4 accidentally falls off, the fall protection device tensions and enters a stressed state to suspend pipe body 4, forming a protection to prevent pipe body 4 from falling and causing personnel injury, and can provide sufficient evacuation time for construction personnel below pipe body 4, thus better ensuring construction safety.

[0040] This embodiment features a modular structure for easy and rapid installation, and the installation process is weld-free, which better ensures that the sheet piles 5 and pipe body 4 of the support structure are not damaged by welding. During construction, an anti-fall safety device provides active anti-fall protection, and the adjustable connection part is better suited to various construction environments, better meeting the needs of the device for repeated use in different construction environments and ensuring construction costs.
