[0002] During construction, support structures are used to protect the foundation pit and ensure the safety of underground structures and the surrounding environment. Currently, anchored and braced structures are the most common types of foundation pit support structures. Compared to anchored structures, braced structures have advantages such as smaller footprint, smaller impact area, and better strength and overall rigidity, and are widely used in foundation pit support systems.

[0003] Chinese patent application number 202422332525.7 discloses a retaining support structure for municipal subway foundation pit engineering, including a lifting plate. A dual-axis motor is fixedly connected to the center of the lifting plate, and telescopic components are provided on both sides of the dual-axis motor. Support plates are provided on both the left and right sides of the lifting plate, and the inner side of the support plates is connected to the telescopic components. A base plate is provided below the lifting plate, and a lifting component is provided inside the base plate. The lifting plate is connected to the base plate through the lifting component. By adjusting the height and width, the adjustable height and width can meet the needs of different construction stages in a timely manner, optimize the construction process, improve construction efficiency, and quickly adjust the height and width of the retaining support structure in the face of emergencies, thereby enhancing the ability to resist risks.

[0004] The retaining support structure used in the municipal subway foundation pit project is not convenient for connecting multiple support devices and for supporting corners, thus reducing its support effect and practicality.

The main support plate 1 and the first side support plate 5 both have second sliding grooves 20 inside. A second sliding rod 21 is slidably connected inside the second sliding groove 20. The main support plate 1 and the second side support plate 15 both have insertion grooves 25 inside, and the second sliding rod 21 is inserted into the insertion groove 25. Two corresponding third slide grooves 22 are provided inside the main support plate 1 and the first side support plate 5 and outside the second slide groove 20. Two corresponding third slide rods 23 are fixedly connected to the outside of the second slide rod 21. The third slide rods 23 are slidably connected inside the third slide groove 22. The stability of the second slide rod 21 is ensured by the mutual cooperation of the two third slide rods 23 and the second slide rod 21. The second slide bar 21 has a first slot 24 inside, and the second side support plate 15 has a second slot 26 inside and outside the insertion slot 25. A connecting rod is inserted into the first slot 24 and the second slot 26. By inserting the second slide bar 21 into the insertion slot 25 and then connecting the connecting rod into the second slot 26 and the first slot 24, the second slide bar 21 is fixed inside the insertion slot 25, thereby connecting multiple support plates. The first side support plate 5 and the second side support plate 15 each have two corresponding second storage slots 16 inside. The second storage slot 16 is provided with a clamping block 17 and a support rod 18 is placed inside the second storage slot 16. The support rod 18 and the clamping block 17 cooperate with each other. The main support plate 1, the first side support plate 5, and the second side support plate 15 each have a support slot 19 inside. The support slot 19 and the support rod 18 cooperate with each other. The second storage slot 16 and the clamping block 17 facilitate the storage of the support rod 18. The cooperation between the support rod 18 and the support slot 19 can support and fix the main support plate 1, the first side support plate 5, and the second side support plate 15. The main support plate 1 has a second internal groove 7 inside. A fixing plate 9 is rotatably connected inside the second internal groove 7 via a rotating shaft. The fixing plate 9 has a snap-fit ​​groove 12 inside. The main support plate 1 can be supported by the cooperation between the fixing plate 9 and the snap-fit ​​groove 12. The main support plate 1 has a first internal groove 6 inside. The first internal groove 6 is rotatably connected to a first support rod 8 through a rotating shaft. The first support rod 8 has a first sliding groove 10 inside. The first sliding groove 10 is slidably connected to a first sliding rod 11 inside. One end of the first sliding rod 11 is inserted into the snap-fit ​​groove 12. The first support rod 8 and the first sliding rod 11 both have slots 13 inside.

[0019] In summary, the foundation pit support structure for this construction project can be manually rotated according to usage requirements. The first side support plate 5 and the second side support plate 15 can be manually rotated to rotate the two rotating arc rods 4, allowing the first side support plate 5 and the second side support plate 15 to unfold on both sides of the main support plate 1. This facilitates support at corners. When multiple main support plates 1 need to be connected, or when connecting the main support plate 1 to the first side support plate 5 and the second side support plate 15, the second sliding rod 21 is manually pushed to insert it into the insertion slot 25. Then, the connecting rod is inserted into the second slot 26 and the first slot 24, thus fixing the second sliding rod 21 within the insertion slot 25. This allows multiple support plates to be connected. When fixing, the fixing plate 9 can be rotated out from the inside of the second internal groove 7 and contacted with the ground. It can then be fixed to the ground with fixing nails. Then, the first support rod 8 is rotated, and the first sliding rod 11 is slid out from the inside of the first sliding groove 10. The first sliding rod 11 is inserted into the inside of the snap-fit ​​groove 12, and then the fixing bolt 14 is inserted into the inside of the slot 13 for fixing. This initially fixes the main support plate 1. Then, the support rod 18 is taken out from the inside of the second storage groove 16, one end is inserted into the ground, and the other end is inserted into the inside of the support groove 19. This further supports and fixes the main support plate 1, the first side support plate 5, and the second side support plate 15.
