Description

Technical Field

[0001] The utility model relates to the technical field of cofferdam structures, in particular to a steel sheet pile cofferdam structure. Background Technique

[0002] The steel sheet pile cofferdam is one of the most commonly used sheet pile cofferdams. The steel sheet pile is a type of profiled steel with a locking groove. Its cross-section has straight plate shape, trough shape, Z shape, etc., with various sizes and interlocking forms. It has high strength and is easy to drive into hard soil layers; it can be constructed in deep water, and when necessary, an inclined support can be added to form a cage, with good waterproof performance; it can be assembled into cofferdams of various shapes as needed and can be reused multiple times. Therefore, it has a wide range of uses.

[0003] The existing steel sheet pile cofferdam structure generally uses a steel frame to support the enclosure panel to form a cofferdam structure, and the cofferdam structure is fixed by inserting the insertion part into the soil. For example, Chinese Patent Publication No. CN219671400U discloses "a steel sheet pile cofferdam structure". Through the combined use of a support frame, a fixed column and a plug rod, the support frame is placed inside the enclosure panel, and then the steel frame is hoisted and placed inside the enclosure panel. The steel frame presses down on the pressing block, and the pressing block drives the T-shaped frame to move downward. The T-shaped frame drives the plug rod to move downward, so that the plug rod is inserted into the soil through the tapered surface opened at the bottom, and then the plug rod plays a role in fixing the support frame to prevent the support frame from undergoing horizontal displacement. The groove at the bottom of the steel frame forms an insertion connection with the top of the fixed column, so that the fixed column supports the steel frame inside the enclosure panel, and then the steel frame is stably supported to avoid the separation and falling of the steel frame from the enclosure panel, improving the support effect of the device;

[0004] In actual use, due to different construction areas involved, there are also different requirements for the specifications of the cofferdam structure. However, preparing cofferdam structures of multiple specifications will not only increase costs, but also require a large storage space, increasing the difficulty of construction.

[0025] The first connecting member 4 and the second connecting member 6 each include two T-shaped portions 41, the two T-shaped portions 41 are fixedly connected, T-shaped slots 42 matching the T-shaped portions 41 are provided on both sides of the frame 3, positioning slots 43 are provided on the T-shaped slots 42, expansion portions 44 corresponding to the positioning slots 43 are fixedly provided on the T-shaped portions 41, and positioning structures 5 matching the expansion portions 44 are provided on the frame 3.

[0026] In the utility model, a plurality of frames 3 are interconnected by a first connecting member 4 to form a frame, and the length of the frame can be adjusted as required, thereby changing the range of the cofferdam structure, and is suitable for construction sites of different areas. Since the first connecting member 4 uses two T-shaped portions 41 to be respectively plugged into the T-slots 42 of the two frames 3, the two frames 3 can be effectively fixed to prevent the frame from disintegrating.

[0027] Furthermore, in the present embodiment, the second connecting member 6 also includes a connecting portion 61 fixedly arranged between the two T-shaped portions 41. The two T-shaped portions 41 are in a right-angle structure, or other angles, preferably a right-angle structure. When the two T-shaped portions 41 are connected to the frame 3, a right-angle connection is formed between the frames to form a cofferdam structure. The cofferdam structure may also be polygonal due to other structures between the two T-shaped portions 41.

[0028] Furthermore, in the present embodiment, the positioning structure 5 includes a slide groove 51 provided on the frame 3, an insert block 52 is slidably arranged in the slide groove 51, and a slot corresponding to the insert block 52 is provided on the expansion portion 44. The insert block 52 is plugged into the slot, thereby fixing the expansion portion 44 and the T-shaped portion 41 to prevent the first connecting member 4 from falling off.

[0029] It should be noted that, in the present embodiment, a through groove is provided on the slide groove 51, a toggle portion 53 is slidably provided on the through groove, a bolt 54 is inserted into the toggle portion 53, and the bolt 54 is threadedly connected to the insert block 52. By arranging the toggle portion 53 and the bolt 54 to cooperate with the insert block 52, when the toggle portion 53 is moved, the insert block 52 will move accordingly, and when the bolt 54 is rotated to make the toggle portion 53 abut against the frame 3, the positions of the toggle portion 53 and the insert block 52 can be fixed.

[0030] In addition, in the present embodiment, a guide hole is provided on the plug block 52, and a guide column 55 movably plugged into the guide hole is fixedly provided at the lower end of the toggle portion 53.

A spring 9 is provided between the abutment plate 8 and the T-slot 42. The abutment plate 8 abuts against the T-shaped portion 41 under the action of the spring 9. When the positioning structure 5 cancels the fixation of the first connecting member 4 or the second connecting member 6, the spring 9 pushes the abutment plate 8 to move upward, driving the first connecting member 4 or the second connecting member 6 to move upward and separate from the T-slot 42 and the positioning slot 43, so as to facilitate the removal of the first connecting member 4 or the second connecting member 6 and thus facilitate the disassembly of the cofferdam structure.

[0032] Working method: When working, multiple frames 3 are connected to each other through the first connecting member 4 to form a frame, and the length of the frame can be adjusted according to needs. The two T-shaped portions 41 of the first connecting member 4 are plugged into the T-shaped slots 42 of the two frames 3, and the second connecting member 6 is plugged into the two frames to be connected. After the two T-shaped portions 41 are connected to the frames 3, a right-angle connection is formed between the frames to form a cofferdam structure. At this time, the spring 9 is elastically deformed under force, and the plug block 52 is plugged into the slot, thereby fixing the expansion portion 44 and the T-shaped portion 41 to prevent the first connecting member 4 from falling off;

[0033] When disassembling the cofferdam structure, when the toggle portion 53 is moved, the insert block 52 moves accordingly and separates from the slot, and the spring 9 pushes the abutment plate 8 upward, driving the first connecting member 4 or the second connecting member 6 to move upward and separate from the T-slot 42 and the positioning slot 43, making it easy to remove the first connecting member 4 or the second connecting member 6 and thus facilitate disassembly of the cofferdam structure.
