Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-4 As shown, the utility model provides a foundation pit edge retaining structure supported by steel sheet piles, including a vertical pole 1, wherein three vertical poles 1 are provided, and one end of the three vertical poles 1 is jointly provided with two railings 8, one end of one of the railings 8 is provided with a reinforcement component 3, and one end of the two railings 8 is jointly provided with a dense mesh safety net 7, and the three vertical poles 1 and one end of the two railings 8 and the dense mesh safety net 7 are jointly provided with a connecting component 2, and the connecting component 2 includes a connecting ring 21, and eight connecting rings 21 are provided. One end of the eight connecting rings 21 is fixedly connected to one end of the two railings 8, and one end of the dense mesh safety net 7 is provided with eight circular holes 25 for use with the connecting rings 21, and the corresponding connecting rings 21 and the inner wall of the circular hole 25 are jointly provided with a connecting rope 26. One end of each of the six slots 23 is provided with two slots 23 for use with the two railings 8, and the inner wall of one side of the six slots 23 is provided with a first connecting hole 24. One end of each of the two railings 8 is provided with three through-type second connecting holes 22, and the inner walls of the corresponding first connecting holes 24 and second connecting holes 22 are commonly threadedly connected with screws 27. Through the provision of the reinforcement component 3, it is convenient to protect the enclosure structure and improve the stability of the enclosure structure. Through the provision of the connecting component 2, the connecting rope 26 is untied, so that the connecting rope 26 is pulled out from the connecting ring 21 and the circular hole 25, so that the dense mesh safety net 7 is removed from the railing 8, and then the screw 27 is rotated from the first connecting hole 24 and the second connecting hole 22 to separate the two railings 8 from the three uprights 1, thereby realizing the effect of rapid disassembly of the enclosure structure. The structure is simple and easy to use.

[0019] The reinforcement assembly 3 includes a first hinge seat 36, and the first hinge seats 36 are provided with two. One end of the two first hinge seats 36 is fixedly connected to one end of one of the railings 8. The inner walls of the two first hinge seats 36 are hinged with diagonal support rods 31 through a rotating shaft, and the two ends of the two diagonal support rods 31 are hinged with second hinge seats 33 through a rotating shaft. The bottom ends of the two second hinge seats 33 are fixedly connected to the mounting plates 32. Mounting holes 35 are provided on both sides of the top of the two mounting plates 32. The inner walls of the four mounting holes 35 are movably penetrated with foundation bolts 34. The mounting plates 32 are installed on the ground by using the foundation bolts 34 in conjunction with the mounting holes 35. At this time, the connection between the second hinge seat 33 and the first hinge seat 36 makes the diagonal support rods 31 inclined, supporting and reinforcing one of the railings 8, thereby improving the stability of the enclosure structure, so that the enclosure structure can better enclose the foundation pit.

[0020] The bottom ends of the three uprights 1 are fixedly connected to a base plate 5, and round holes 6 are provided on both sides of the top of the three base plates 5. The round holes 6 are used in conjunction with the base plates 5 to facilitate the installation of the base plates 5 on the ground by inserting expansion wires through the round holes 6, thereby achieving better installation of the uprights 1.

[0021] The bottom ends of the three base plates 5 are fixedly connected with four long pointed cones 4, and the corresponding four long pointed cones 4 are distributed in a rectangular array. The long pointed cones 4 are used in conjunction with the base plates 5 to facilitate the base plates 5 to be placed more firmly on the ground.

[0022] The dense mesh safety net 7 is hollow, and the outer surfaces of the three uprights 1 and the two railings 8 are all made of reflective materials, which makes the enclosure structure more eye-catching, better reminds passers-by, and enables the enclosure structure to achieve the best use effect.

[0023] The four corresponding connecting rings 21 are distributed at equal intervals, and the outer surfaces of the eight connecting ropes 26 are all made of anti-slip material.

[0024] The corresponding inner wall threads of the first connecting hole 24 and the second connecting hole 22 match the outer surface threads of the screw 27, so that the first connecting hole 24 and the second connecting hole 22 can better cooperate with the screw 27 for use.

[0025] The four foundation bolts 34 are all made of corrosion-resistant material, which prolongs the service life of the foundation bolts 34 and prevents the foundation bolts 34 from being corroded by the soil under the ground.

[0026] Working principle: First, install the bottom plate 5 at a suitable position on the ground through the circular hole 6 and the bottom plate 5 by using expansion wire through the circular hole 6, so that the three vertical poles 1 are installed next to the foundation pit;

[0027] At the same time, the long pointed cone 4 is used in conjunction with the bottom plate 5 to facilitate the bottom plate 5 to be placed more firmly on the ground, and then the enclosure structure is assembled through the connecting component 2 to enclose the foundation pit;

[0028] Reflective materials make the enclosure structure more eye-catching, better remind passers-by, and achieve the best use effect of the enclosure structure;

[0029] While enclosing, the mounting plate 32 is mounted on the ground through the reinforcement assembly 3 and the foundation bolts 34 in conjunction with the mounting holes 35;

[0030] At this time, the connection between the second hinge seat 33 and the first hinge seat 36 makes the diagonal support rod 31 inclined, supporting and reinforcing one of the railings 8, thereby improving the stability of the enclosure structure;

[0031] When the enclosure structure needs to be dismantled, the connecting rope 26 is untied through the connecting assembly 2, so that the connecting rope 26 is pulled out from the connecting ring 21 and the circular hole 25, so that the dense mesh safety net 7 is removed from the railing 8;

[0032] Then rotate the screw 27 from the first connecting hole 24 and the second connecting hole 22 to separate the two railings 8 from the three uprights 1, then remove the expansion wire and foundation bolts 34 to pull the uprights 1 out of the ground, and quickly disassemble the enclosure structure.

[0033] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
