[0002] At present, dynamic compaction construction, as a method for large-area foundation treatment, has been very common. During the construction process, due to dynamic compaction extrusion, sand and gravel will splash, which is an important potential safety hazard in dynamic compaction construction. Generally, during the construction process, construction workers will remind surrounding operators to pay attention.
[0003] Existing shielding structures are all simply shielded by shielding nets, with a small range and low stability. Moreover, after the shielding net is subjected to the force of sand and gravel splashing, it will deform and is prone to damage over time. Therefore, this application provides a fixing device for preventing gravel from splashing during dynamic compaction construction. Content of the Utility Model
[0004] The utility model aims to solve the problems of small range and low stability in the existing simple shielding by shielding nets, and provides a fixing device for preventing gravel from splashing during dynamic compaction construction, including a support frame and a shielding net arranged on the support structure. The support frame is composed of two vertical beams and one cross beam. A number of U-shaped support structures are arranged between the two vertical beams. A number of first fixing chains and second fixing chains are arranged between the cross beam and the topmost U-shaped support structure, and between adjacent U-shaped support structures. A number of shielding areas are formed between adjacent U-shaped support structures, first fixing chains, second fixing chains and vertical beams. A shielding net is arranged in the shielding areas. The first fixing chain is arranged on the side close to the vertical beam, and the second fixing chain is arranged close to the center of the U-shaped support structure. The first fixing chain is used to fix the U-shaped support structure, and the second fixing chain is used to fix the shielding net.

[0006] Optionally, the shielding net is a dense mesh net, and the dense mesh net is fixedly arranged on the shielding area by binding, so that the dense mesh net spreads and covers the U-shaped support structure, the first fixing chain and the second fixing chain.
[0007] Optionally, the vertical beam inclines 3° - 5° towards the center, and the spacing between corresponding U-shaped support structures gradually decreases from top to bottom.
[0008] Optionally, a fixing block is further arranged on the support frame. The fixing block is welded to the cross beam. A jack is arranged on the fixing block. A pick rod is inserted into the jack.

[0010] Optionally, both the first fixing chain and the second fixing chain are two full-length iron guide chains.
[0011] Advantages of the utility model:

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides a fixing device for preventing gravel from splashing during dynamic compaction construction. As Figure 1 shown, it includes a support frame and a shielding net 4 arranged on the support structure. It is characterized in that the support frame is composed of two vertical beams 1 and one cross beam 2. A number of U-shaped support structures 3 are arranged between the two vertical beams 1. A number of first fixing chains 5 and second fixing chains 6 are arranged between the cross beam 2 and the topmost U-shaped support structure 3 and between adjacent U-shaped support structures 3. A number of shielding areas are formed between adjacent U-shaped support structures 3, first fixing chains 5, second fixing chains 6 and vertical beams 1. A shielding net 4 is arranged in the shielding areas. The first fixing chain 5 is arranged on the side close to the vertical beam 1, and the second fixing chain is arranged at the center of the U-shaped support structure 3. The first fixing chain 5 is used to fix the U-shaped support structure 3, and the second fixing chain is used to fix the shielding net 4. The shielding net 4 in the shielding area shields the gravel from splashing during dynamic compaction construction. The U-shaped support structure 3 can widen the shielding range and reduce the range of sand and gravel splashing.
[0023] As Figure 2 shown, among them, the U-shaped support structure 3 is formed by bending 5 pieces of round steel bars with a diameter of ￠8 by a bending machine.
[0024] On the basis of the above implementation manner, in a preferred implementation manner, as Figure 3 、 Figure 4 shown, the U-shaped support structure, the longitudinal guide chain 5, and the support connecting piece 6 are integrally formed by welding. The shielding net 4 is a dense mesh net. The advantages of the dense mesh net are: the mesh knots are firm and do not slip, the mesh eyes are not easy to deform, and the size of the mesh body is stable; it is firm and durable. The dense mesh net is fixedly arranged in the shielding area by tying, so that the dense mesh net covers the U-shaped support structure 3, the first fixing chain 5 and the second fixing chain 6 flatly. That is, several pieces of dense mesh nets are tied in the first area 41, the second area 42, the third area 43 and the fourth area 44, and ropes, iron wires, etc. can be used for tying.
[0025] On the basis of the above implementation manner, in a preferred implementation manner, the vertical beam 1 inclines 3°-5° towards the center, and the distance between the corresponding U-shaped support structures 3 decreases sequentially from top to bottom. The vertical beam 1 is set at a certain inclination angle, which ensures the installation stability of the fixing device and avoids the vertical beam 1 being knocked crooked due to excessive or too dense force of the flying gravel.
[0026] On the basis of the above embodiments, in a preferred embodiment, as Figure 6 shown, a fixing block 9 is further provided on the support frame. The fixing block 9 is welded to the cross beam 2. A jack is provided on the fixing block 9. A pick rod 8 is inserted into the jack. The pick rod 8 is fixedly connected to the fixing block 9 by a screw 7. The pick rod 8 is welded to the ends of the first fixing chain 5 / the second fixing chain 6.
[0027] Among them, both the first fixing chain 5 and the second fixing chain 6 are two full-length iron guide chains.
[0028] The working principle and beneficial effects of this embodiment are as follows: First, determine the distance between the U-shaped support structures 3 according to the inclination angle of the vertical beam 1, and then weld the U-shaped support structures 3 between the two vertical beams 1. After welding, insert the pick rod 8 into the fixing block 9, and then fix the screw 7 to make the longitudinal guide chain 5 and the support structure connecting piece all hang down. Then weld the first fixing chain 5 and the second fixing chain 6 to the already welded U-shaped support structure 3. Finally, tie safety nets with small mesh openings in the first area 41, the second area 42, the third area 43 and the fourth area 44. When the safety net with small mesh openings is used for too long, only disassemble and replace the safety net with small mesh openings. The structure of the utility model is simple, the assembly and disassembly are convenient and fast, which is convenient for use and improves the safety in dynamic compaction construction. The splashing of gravel during the dynamic compaction construction is blocked by the shielding net 4 in the shielding area. The U-shaped support structure 3 can make the shielding range wider and reduce the range of splashing of sand and gravel. The U-shaped support structure 3 is fixed by the first fixing chain. Even if the connection between the U-shaped support structure 3 and the vertical beam 1 is broken, since the first fixing chain is arranged on the side close to the vertical beam 1, it can also ensure that the U-shaped support structure 3 will not shift, avoiding gravel flying over and hurting the staff. The shielding net 4 is fixed by the second fixing chain to avoid damage to the shielding net 4.
