[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] like Figures 1 to 10 As shown, a protective structure for Larssen sheet pile support includes: a protective component, comprising a protective net 2, both ends of which are fixedly connected to two risers 5 respectively, and a rod 503 fixedly mounted at the lower end of the riser 5, the lower end of the rod 503 having an inverted conical structure, the diameter of the rod 503 matching the inner diameter of the riser 5; a connecting plate 501, the upper end of the riser 5 being fixedly mounted; and a diagonal bracing component 3, one end of which is connected to the Larssen sheet pile 1, and the other end of which is connected to the connecting plate 501, the length of which is adjustable.
[0022] The diagonal bracing component 3 connects the upper end of the protective component to the Larssen steel plate 1, which improves the structural strength of the protective structure and makes the protective component less prone to collapse.
[0023] When multiple protective heights are required, the two protective components are stacked, and the insert rod 503 of the upper protective component is inserted into the inside of the riser 5 of the lower protective component, which makes operation convenient and improves work efficiency.
[0024] The protective assembly also includes a telescopic rod 4, which comprises a receiving pipe 403 and an inner rod 401. The inner rod 401 is movably connected to the inside of the receiving pipe 403. A connecting pipe 402 is fixed to the end of the receiving pipe 403 away from the inner rod 401, and a connecting pipe 402 is also fixed to the end of the inner rod 401 away from the receiving pipe 403. One end of the connecting pipe 402 of the telescopic rod 4 is connected to a vertical pipe 5, and the other end of the connecting pipe 402 of the telescopic rod 4 is connected to another vertical pipe 5. The telescopic rod 4 improves the structural strength of the protective assembly and can adjust its length according to the length of the protective net 2, thus broadening its applicability.
[0025] A threaded hole is opened on the inner side of the upper end of the riser 5. The diameter of the threaded hole is larger than the inner diameter of the riser 5. Each riser 5 is equipped with an indicator light 6. A stud 601 is fixed at the lower end of the base plate of the indicator light 6. The stud 601 passes through the connecting pipe 402 and is threaded to the inner side of the upper end of the riser 5. The indicator light 6 adopts, but is not limited to, the existing solar warning light and roadblock light, which emits a yellow light at night to indicate the scope of the pit. The stud 601 can also play the role of fixing the telescopic pole 4 above.
[0026] There are two telescopic rods 4. One telescopic rod 4 is connected to the upper end of the riser 5, and the other telescopic rod 4 is connected to the lower end of the riser 5. The insertion rod 503 passes through the connecting pipe 402 of the lower telescopic rod 4 and is inserted into the soil. The two telescopic rods 4 further improve the structural strength of the protective component. The insertion rod 503 plays the role of fixing the lower telescopic rod 4.
[0027] The receiving pipe 403 has a through hole 1, and multiple through holes 1 are evenly arranged along the length of the receiving pipe 403. The inner rod 401 has a through hole 2 corresponding to the through hole 1. The connecting bolt 404 passes through the through hole 2 and is threadedly connected to the nut. The setting of the through hole 1, through hole 2 and connecting bolt 404 facilitates the adjustment of the length of the telescopic rod 4, which is suitable for protective nets 2 of different lengths.
[0028] The diagonal brace assembly 3 includes an adjusting tube 304 and two screws 303, one of which is a positive thread screw 303 and the other is a negative thread screw 303. Both ends of the adjusting tube 304 are threadedly connected to the two screws 303 respectively. The upper end of the diagonal brace assembly 3 is inclined away from the foundation pit. The upper screw 303 is hinged to the first connecting member 301. Two connecting posts 302 are fixed on the first connecting member 301. A connecting plate 501 has connecting holes 502 that match the connecting posts 302. The connecting posts 302 pass through the connecting holes 502 and are threadedly connected to nuts. The length of the diagonal brace assembly 3 can be adjusted by rotating the adjusting tube 304. The two connecting posts 302 of the first connector 301 are located inside the connecting holes 502 at the adjacent ends of the adjacent protective components. The connecting plate 501 is provided with a connecting hole 502. The two connecting posts 302 of the first connector 301 can adjust the included angle between two adjacent protective components according to the shape of the pit, thus broadening the scope of application.
[0029] The lower screw 303 is hinged to the second connector 307, the second connector 307 is fixedly connected to the positioning member 305, and the positioning member 305 is detachably connected to the Larssen steel plate 1.
[0030] The positioning component 305 is a U-shaped component. The Larssen steel plate 1 is located inside the two vertical plates of the U-shaped component. A fixing nut is fixed on the vertical plate near the foundation pit. The locking bolt 306 is threadedly connected to the fixing nut and tightens the Larssen steel plate 1. The positioning component 305 is detachably connected to the Larssen steel plate 1 through the fixing bolt, which facilitates installation and disassembly and improves work efficiency.
[0031] The protective net 2 is a flexible protective net 2, with both ends of the protective net 2 wrapped around the outside of the two risers 5 respectively; the protective net 2 is a metal protective net 2 or a woven fabric net, and the protective net 2 is wrapped around the outside of the riser 5. The length of the protective component is adjusted according to the foundation pit conditions, and the installation of the telescopic rod 4 further improves the applicability of the protective structure.
[0032] Work process: Insert the rods 503 of the vertical pipes at both ends of the protective assembly into the soil outside the pit, connect the first connector 301 at the upper end of the diagonal brace assembly 3 to the connecting plate 501, and then connect the lower end of the diagonal brace assembly 3 to the Larssen steel plate 1 using the positioning piece 305.
[0033] The protective components are quickly connected via vertical pipes and diagonal bracing components 3, which improves work efficiency. They can also be reused after disassembly, reducing construction costs. Depending on the conditions of the foundation pit, the protective height can be adjusted by connecting the insert rod 503 to the vertical pipe, thus broadening the scope of application.
