[0002] Steel sheet piles act as important structural materials in permanent projects such as building foundations, underground projects, port terminals, shipyards, sluices, waterway revetments, artificial islands, breakwaters, revetments and slope protection structures of road bridges, retaining walls, impervious walls, and foundation reinforcement; they are key materials in temporary projects such as foundation pit support, temporary revetments, water-stop cofferdams, and retaining walls; in the prevention, control, and emergency rescue of sudden geological disasters such as floods, collapses, subsidence, quicksand, debris flows, and landslides, steel sheet piles are even synonymous with high efficiency and speed. After the construction of a steel sheet pile cofferdam is completed, a support structure needs to be installed inside it. Conventionally, in a steel sheet pile foundation pit support structure, a bracket is usually connected to the steel sheet pile by welding, and then the waling is installed on the bracket. The installation process is time-consuming, and the strength of the connection part is largely affected by the welding quality. Moreover, the connection method between the bracket and the steel sheet pile is a rigid connection. In special geological conditions, if the foundation pit support structure deforms and causes the welding joint to be damaged, the welding connection may instantly lose its connection strength and cause the waling to fall; when the bracket is disassembled later, cutting is required, and the bracket and the steel sheet pile will be damaged to varying degrees during the cutting process, affecting secondary utilization.

A connecting device for a steel sheet pile support structure includes a steel sheet pile 1 and a bracket 2. The steel sheet pile 1 includes a flat plate 11 and two flange plates 12 respectively connected to both ends of the flat plate 11. A plurality of first threaded holes 13 are provided on the flange plate 12, and the plurality of first threaded holes 13 are arranged at equal intervals along the length direction of the flange plate 12. The bracket 2 includes a support plate 21 and two side plates 22 respectively connected to both ends of the support plate 21. The two side plates 22 correspond to the two flange plates 12 one by one. Second threaded holes 23 are provided on the side plates 22, and the second threaded holes 23 on the side plates 22 are connected to any one of the first threaded holes 13 on the corresponding flange plate 12 by bolts 3, so that the side plates 22 are installed on the corresponding flange plates 12.

[0021] A locking buckle 14 is provided at one end of the flange plate 12 away from the flat plate 11. Adjacent two steel sheet piles 1 are connected through the locking buckles 14 on the flange plates 12, and thus a plurality of steel sheet piles 1 are connected in sequence to form a steel sheet pile 1 cofferdam. When installing the bracket 2, first determine the steel sheet pile 1 connected to the bracket 2 and determine the installation height of the bracket 2 to determine the first threaded holes 13 respectively connected to the two side plates 22 of the bracket 2. Then threadedly connect the second threaded holes 23 on the side plates 22 to the corresponding first threaded holes 13 on the corresponding flange plates 12 through bolts 3, so that the side plates 22 are installed on the corresponding flange plates 12, thereby enabling the bracket 2 to be installed on the corresponding steel sheet pile 1 and making the installation height of the bracket 2 located at the preset installation height. Then install an I-beam purlin 5 on the bracket 2 and set a number of cross braces 6 on the I-beam purlin 5 to form a foundation pit steel sheet pile 1 support structure.

[0022] In order to make the connection between the side plate 22 and the corresponding flange plate 12 more firm and stable, in an embodiment, the number of the second threaded holes 23 on the side plate 22 is set to two, and the distance between the two second threaded holes 23 is the same as the distance between two adjacent first threaded holes 13 on the flange plate 12.

The plurality of nuts respectively correspond to the plurality of first threaded holes 13 one by one, and the nuts can be selectively installed in the corresponding first threaded holes 13, and the nuts are threadedly connected to the corresponding first threaded holes 13. Before the construction of the steel sheet pile 1, a plurality of nuts are correspondingly installed in the plurality of first threaded holes 13 to ensure the sealing performance of the first threaded holes 13 during the construction of the steel sheet pile 1. After the construction of the steel sheet pile 1 is completed, the installation position of the I-beam waling 5 is determined according to the design of the foundation pit support structure, so as to determine the height position of the corbel 2, and the nuts in the first threaded holes 13 corresponding to the height position of the corbel 2 are removed. At this time, the two side plates 22 of the corbel 2 can be installed on the corresponding height of the flange plate 12 through the bolts 3.
