[0002] Larsen steel sheet pile is also called U-shaped steel sheet pile. As a new type of building material, it is used as retaining wall, water retaining wall and sand retaining wall in bridge cofferdam construction, large pipeline laying and temporary ditch excavation; it is used as retaining wall, retaining wall and embankment revetment at docks and unloading yards, playing an important role in engineering. In the construction process of Larsen steel sheet pile, a pile driver is used to drive the Larsen steel sheet pile. The bus pile driver is generally modified with a crawler crane or an excavator plus a vibratory hammer. In the construction process of Larsen steel sheet pile, the force generated by the hydraulic clamp of the vibratory hammer is mainly used to lift the Larsen steel sheet pile into the air. There is a safety risk that the hydraulic clamp of the vibratory hammer is not firm, which makes the Larsen steel sheet pile fall off. At present, the problem of Larsen steel sheet pile falling off is mainly handled by on-site inspection and safety inspection before construction. There is a problem of manpower input for inspection, so we have designed a setting for preventing Larsen steel sheet pile from falling off, which does not require too much manpower to solve the safety problem of Larsen steel sheet pile falling off.

[0023] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0024] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0025] See Figure 1-3 This is an embodiment of the anti-falling device of Larsen steel sheet pile in the utility model.

[0026] First, set an anti-falling opening 2 with a diameter of about 10 cm on the Larsen steel sheet pile 1 where construction is required. Try to set it on the upper part of the Larsen steel sheet pile 1 so that the upper part of the Larsen steel sheet pile 1 can be exposed after it is driven into the ground. According to the actual needs of the project, it can also be set between 20 cm and 50 cm from the top of the Larsen steel sheet pile 1.

[0027] Connect the wire rope 13 to the vibratory hammer 14 on the excavator 15. The length of the wire rope 13 can be adjusted according to the length of the Larsen steel sheet pile 1, generally 15% of the length of the Larsen steel sheet pile 1, but not less than 1m;

[0028] Before the formal construction, the Larsen steel sheet pile 1 and the vibratory hammer 14 are connected with a steel wire rope 13 to form an anti-falling device. When the hydraulic clamp of the vibratory hammer 14 clamps the Larsen steel sheet pile 1 into the air, it prevents the Larsen steel sheet pile 1 from falling directly and causing safety hazards.

[0029] The Larsen steel sheet pile 1 is driven into the ground. After the construction is completed, the steel wire rope 13 can be recovered and reused multiple times;

[0030] After the construction is completed, when the Larsen steel sheet pile 1 is pulled out, a vibratory hammer 14 is used for construction, and the vibratory hammer 14 and the Larsen steel sheet pile 1 are also connected by a steel wire rope 13.

[0031] At the same time, an anti-falling component 3 is provided in the anti-falling mouth 2 in this device, and the anti-falling component 3 includes a mounting ring 4 arranged in the anti-falling mouth 2, and a bent hook plate 5 is provided in the mounting ring 4. There are two bent hook plates 5, which are symmetrically arranged on the inner ring wall of the mounting ring 4, and a first gap 7 is formed between the bent hook plates 5.

[0032] When the wire rope 13 passes through the anti-dropping opening 2, it will pass through the first gap 7 which is slightly larger than the diameter of the wire rope 13, and then enter the limited space formed by the two bent hook plates 5 and the mounting ring 4; when the excavator 15 is lifting, the Larsen steel sheet pile 1 will

[0033] Mounting arc plates 8 are provided at the front and rear ends of the mounting ring 4, and fixing plates 9 are provided at both ends of the mounting arc plates 8. Threaded holes are provided in the fixing plates 9, and mounting holes corresponding to the threaded holes are provided on the Larsen steel sheet pile 1. The fixing plates 9 and the Larsen steel sheet pile 1 are connected by bolts 10.

[0034] The mounting arc plate 8 in this device is mainly used to fix the mounting ring 4 in the anti-fall-off opening 2. The specific fixing method adopts a fixing plate 9. The threaded hole of the fixing plate 9 corresponds to the mounting hole on the Larsen steel sheet pile 1, and then the bolt 10 is rotated and inserted into the threaded hole, and the nut is screwed on; this can improve the stability of the mounting ring 4.

[0035] A support plate 11 is further provided in the mounting ring 4 . One end of the support plate 11 is fixed to the mounting ring 4 , and the other end is fixed to the bent hook plate 5 .

[0036] The function of the support plate 11 in this device is to support the bending hook plate 5. Due to the shaking of the Larsen steel sheet pile 1, the steel wire rope 13 will move in the space formed by the bending hook plate 5, and at this time, a force will be generated on the bending hook plate 5, and the bending hook plate 5 may be deformed by the force; the support plate 11 can provide supporting force for the bending hook plate 5 and help the bending hook plate 5 to stabilize.

[0037] A second gap 12 is formed between the support plates 11 , and the second gap 12 is larger than the first gap 7 . The middle portion of the support plates 11 is bent toward the center portion of the mounting ring 4 .

[0038] The function of the first gap 7 and the second gap 12 in this device is to facilitate the steel wire rope 13 to enter the space formed by the bending hook plate 5 and the mounting ring 4; at the same time, the function of the second gap 12 is that when the support plate 11 receives the force from the bending hook plate 5, if the force is very large, the support plate 11 will bend toward the center, and at this time the second gap 12 will become smaller until the two support plates 11 contact, and at this time the two support plates 11 press together to provide new supporting force, which can further stabilize the bending hook plate 5.

[0039] The material of the support plate 11 is an elastic alloy; this device uses elastic steel, which has strong supporting performance without lacking elastic deformation ability.

[0040] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
