Description

Technical Field

[0001] The utility model relates to the field of flood control, in particular to a flood passing protection device for foundation pits. Background Art

[0002] During the progress of construction projects, the excavation of foundation pits is an essential part. However, due to the construction progress being restricted by various factors, it is sometimes difficult to complete the construction work of the buildings inside the foundation pits before the arrival of the flood season. As the flood season approaches, the foundation pits are at risk of being flooded by floodwaters, which undoubtedly poses great challenges to the construction. Even more severely, when the floodwaters recede, silt will deposit on the concrete bonding surfaces inside the foundation pits, forming a stubborn interface layer. The characteristic of being difficult to completely remove not only greatly increases the difficulty of subsequent construction, but may also have a serious negative impact on the structural stability and construction quality of the entire building. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to Figure 1-6As shown in the figure, an embodiment of the present application provides a technical solution: a flood protection device for a foundation pit, including a sealing frame 1. A through groove is provided in the middle of the sealing frame 1. A cover plate 2 is provided on the sealing frame 1. A first single plate 3 is also provided in the through groove between the sealing frame 1 and the cover plate 2. A plurality of first screws 4 for vertically pressing the cover plate 2 downward are provided on the sealing frame 1. A second single plate 5 and a third single plate 6 are respectively provided on both sides of the first single plate 3. A second screw 7 is provided on one side of the second single plate 5. Corresponding connection holes are provided on the first single plate 3 and the third single plate 6. The second screw 7 passes through the connection holes on the first single plate 3 and the third single plate 6, and then nuts are installed at one end to tightly fix the first single plate 3, the second single plate 5, and the third single plate 6 together.

[0024] The sealing frame 1 is fixed to the foundation that needs to be made in front of the foundation pit. The sealing frame 1 and the foundation can be cast into one body or made into one body in other ways. This is mainly to ensure that water can only flow through the through groove of the sealing frame 1. Threaded holes are provided at the bottom of the sealing frame. The first screw 4 is installed in the threaded holes of the sealing frame 1. The first single plate 3 is closely attached to the sealing frame 1. When the first screw 4 is tightened, the cover plate 2 tightly presses the first single plate 3, thereby pressing the first single plate 3 tightly.

[0025] The sealing frame 1 can be a long plate, blocking the water coming from the front in front of the foundation pit. The sealing frame 1 can also be rectangular, circular, etc., surrounding the perimeter of the foundation pit. Corresponding through grooves are provided in each direction of the sealing frame 1, and corresponding cover plates 2, first single plates 3, second single plates 5, and third single plates 6 are provided in the through grooves. The setting principle is the same as that described above.

[0026] The purpose of setting the second single plate 5 and the third single plate 6 is to increase the thickness of the first single plate 3 equivalently, thereby improving the ability to block a larger flood season, because the lower parts of the second single plate 5 and the third single plate 6 are in contact with the sealing frame 1, thereby transferring the overall force to the sealing frame 1.

[0027] In a preferred solution, the areas of the second single plate 5 and the third single plate 6 are larger than that of the first single plate 3, and can cover the joints between the first single plate 3 and the left and right sides of the sealing frame 1.

[0028] In this way, at the joints between the left and right sides of the sealing frame 1 and the two sides of the first single plate 3, it is beneficial to improve the sealing performance of the first single plate 3 and prevent flood water from flowing into the foundation pit from the joints.

[0029] In a preferred solution, first through holes 51 are provided at both ends of the side surface of the second single plate 5. Rivets 52 that do not protrude from the side surface of the second single plate 5 are provided in the first through holes 51. Unthreaded holes 521 that do not penetrate are provided on one side of the rivets 52 corresponding to the first single plate 3. The second screw 7 is connected to the threaded holes 521 of the rivets 52.

[0030] The rivet 52 does not protrude from one side of the second single board 5 so that the first single board 3 and the second single board 5 can be better fitted together.

[0031] In a preferred embodiment, a backing plate 8 may also be provided between the first single board 3 and the second single board 5 or between the first single board 3 and the third single board 6. A third through hole 81 corresponding to the first single board 3 is provided on the backing plate 8, and the third through hole 81 is a U-shaped groove matching the second screw 7.

[0032] By setting the backing plate 8 in this way, it can be inserted between the first single board 3 and the second single board 5 from above. The purpose of setting the backing plate 8 is still to overall enhance the blocking strength of the first single board 3.

[0033] In a preferred embodiment, the first single board 3, the second single board 5 and the third single board 6 are composed of a hollow stainless steel plate and polyester foam filled in the hollow of the stainless steel plate. The first through hole (51) is also formed by the stainless steel plate.

[0034] The first single board 3, the second single board 5 and the third single board 6 are generally of the same structure.

[0035] Sealing rubber strips may also be provided around the first single board, and sealing rubber strips are also provided around the sides where the second single board, the third single board and the first single board are joined, so as to improve the overall sealing performance.

[0036] In a preferred embodiment, a second through hole (32) is provided in the middle of the first single board 3, and the second screw 7 passes through the second through hole 32.

[0037] In a preferred embodiment, a reinforcing rib 61 is further provided on one side of the third single board 6.

[0038] In a preferred embodiment, the sealing frame 1 is rectangular, and through grooves are provided on each side of the sealing frame 1.

[0039] Corresponding through grooves are provided in each direction of the sealing frame 1, and corresponding cover plates 2, the first single board 3, the second single board 5, the third single board 6, etc. are provided in the through grooves. The setting principle is the same as that described above.

[0040] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
