Description

Technical Field

[0001] The utility model relates to the technical field of lock cofferdams, in particular to a water-stopping and leak-proofing material structure at a connection of a lock cofferdam. Background Art

[0002] A cofferdam refers to a temporary retaining structure built during the construction of permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be carried out within the cofferdam, foundation pits can be excavated, and buildings can be constructed. It is generally used in hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use.

[0003] For example, a steel pipe column lock buckle cofferdam is disclosed in the Chinese utility model patent publication number (CN220080068U), which includes a steel pipe column, a lock buckle and an airbag. Adjacent steel pipe columns are connected together by the lock buckle, and the airbag is placed in the space inside the lock buckle. The airbag is inflated by an air pump to maintain a certain pressure inside the airbag so that the airbag fills the entire space of the lock buckle to form a water-blocking structure. This utility model solves the problem that the cofferdam leaks due to the large number of lock openings and the influence of wind and waves, which causes local deformation of the cofferdam and makes most waterproof and leak-proofing problems very difficult. However, in this patent, the airbag is inflated to achieve a sealing and water-blocking effect at the connection, and the airbag is inside the lock buckle. The outside world cannot observe the inflation of the airbag, which makes it difficult to judge the water-blocking effect of the airbag. At the same time, the inner wall of the lock buckle cannot be ensured to be completely smooth. If it is not inflated enough, the water-blocking effect will be affected. If it is inflated too much, the protruding structure of the inner wall of the lock buckle will damage the airbag, affecting its practicality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a water-stopping and leak-proofing material structure at the joint of the lock cofferdam, which has the advantages of improving the water-stopping and leak-proofing effect and preventing water from seeping into the construction site. It solves the problem in the patent that the joint is sealed and water-blocked by inflating an airbag, while the airbag is inside the lock, and the inflation of the airbag cannot be observed by the outside, making it difficult to judge the water-blocking effect of the airbag. At the same time, the inner wall of the lock cannot be ensured to be completely smooth. If it is insufficiently inflated, the water-blocking effect will be affected. If it is too inflated, the protruding structure of the inner wall of the lock will damage the airbag, affecting practicality.

[0008] Furthermore, the number of the mounting holes and the number of the rotating blocks are both two, and they are symmetrically distributed up and down with respect to the central axis of the mounting plate.

[0009] Furthermore, the support assembly includes a rack, which is meshed with the outer side of the gear. A connecting block is fixed to the upper surface of the rack. The left side of the connecting block penetrates and extends to the left side of the fixed plate and is fixed with a support plate. A limiting plate is fixed to the left side of the support plate.

[0010] Furthermore, there are two racks, which are symmetrically distributed around the central axis of the gear. Two sliding rods are fixed between the left and right inner walls of the fixed plate, and the two sliding rods are respectively slidably connected to the inner sides of the two racks.

[0011] Furthermore, the water-stopping mechanism comprises a water-absorbing layer, the water-absorbing layer is fixed to the back side of the mounting plate, an expansion layer is fixed to the inner side of the water-absorbing layer, and sealing pads are fixed to the front sides of the two limit plates.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The water-stopping and leak-proofing material structure at the connection of the lock cofferdam can be used to rotate the rotating block with a hexagonal wrench through the cooperation of the hexagonal groove, thereby driving the connecting rod to rotate. The rotation of the connecting rod can drive the gear to rotate, thereby driving the rack to move.

[0015] 2. The water-stopping and leak-proofing material structure at the joint of the lock cofferdam can absorb the moisture around the cofferdam through the cooperation of the water-absorbing layer, so that the moisture reaches the expansion layer on the inside. Through the cooperation of the expansion layer, it will expand and become hard after absorbing water. Through the cooperation of the sealing gasket, the expanded expansion layer squeezes the connecting plate, so that the connecting plate fits tightly against the sealing gasket, thereby completing the water-stopping and leak-proofing work of the cofferdam.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In this embodiment, a water-stopping and leak-proof material structure at the connection of a locking cofferdam comprises a locking steel pipe column 1, a connecting plate 2 is fixed to the outer side of the locking steel pipe column 1, a mounting plate 3 is provided on the front side of the connecting plate 2, and a connecting mechanism 4 for conveniently connecting the locking steel pipe column 1 is provided on the mounting plate 3, so that the locking steel pipe columns 1 can be connected to form a cofferdam, which is convenient for construction in water, and a water-stopping mechanism 5 for convenient water-stopping and leak-proofing is provided on the mounting plate 3, so that the connection of the locking cofferdam can remain tightly sealed and improve the waterproof performance.

[0023] There are two connecting plates 2 , which are symmetrically distributed on the left and right sides of the central axis of the locking steel pipe column 1 , so as to facilitate the connection between the locking steel pipe columns 1 .

[0024] See also Figure 2 In order to connect the locking steel pipe columns 1 to form a cofferdam and facilitate construction in water, the connecting mechanism 4 in this embodiment includes a rotating block 401, a mounting hole 402 is provided on the front of the mounting plate 3, the rotating block 401 is rotatably connected to the inner side of the mounting hole 402 through a sealed bearing, a hexagonal slot 403 is provided on the front of the rotating block 401, and then a hexagonal wrench is inserted into the hexagonal slot 403, so that the hexagonal wrench drives the rotating block 401 to rotate, a fixing plate 404 is fixed on the back of the mounting plate 3, and a connecting rod 405 is fixed on the back of the rotating block 401. The rotation of the rotating block 401 drives the connecting rod 405 to rotate, and the other end of the connecting rod 405 penetrates and extends to the inside of the fixing plate 404, and a gear 406 is fixed on the outside, and the connecting rod 405 drives the gear 406 to rotate, and a supporting assembly is provided on the gear 406.

[0025] In this example, the number of the mounting holes 402 and the number of the rotating blocks 401 are both two, and both are symmetrically distributed up and down about the central axis of the mounting plate 3, thereby improving the stability of the locking cofferdam connection.

[0026] It should be noted that the supporting assembly includes a rack 407, which meshes with the outer side of the gear 406, and the gear 406 drives the rack 407 to move. A connecting block 408 is fixed to the upper surface of the rack 407, and the rack 407 drives the connecting block 408 to move. The left side of the connecting block 408 passes through and extends to the left side of the fixed plate 404, and is fixed with a support plate 409. The connecting block 408 drives the support plate 409 to move, so that the support plate 409 fits with the connecting plate 2, so that the position of the mounting plate 3 remains stable. A limiting plate 410 is fixed to the left side of the support plate 409, and the limiting plate 410 can prevent the connecting plate 2 from being disengaged. There are two racks 407, which are symmetrically distributed around the central axis of the gear 406. Two sliding rods are fixed between the inner walls on the left and right sides of the fixed plate 404, and the two sliding rods are respectively slidably connected to the inner sides of the two racks 407.

[0027] See also Figure 3-4 In order to keep the joint of the lock cofferdam tightly sealed and improve the waterproof performance, the water-stopping mechanism 5 in this embodiment includes a water-absorbing layer 501, which is fixed to the back of the mounting plate 3, and an expansion layer 502 is fixed on the inner side of the water-absorbing layer 501. The water-absorbing layer 501 can absorb the surrounding moisture and slow down the speed of moisture and the expansion layer 502. The front sides of the two limiting plates 410 are fixed with sealing pads 503. The expanded expansion layer 502 squeezes the connecting plate 2, so that the connecting plate 2 and the sealing pad 503 on the limiting plate 410 fit tightly, thereby completing the water-stopping and leak-proofing work.

[0028] In this example, the water-absorbing layer 501 is a sponge layer, and the expansion layer 502 is an expanded perlite layer. The number of water-absorbing layers 501 is equal to the number of sealing pads 503, and the positions correspond one to one. The sponge material of the water-absorbing layer 501 quickly absorbs moisture and allows excess moisture to enter the inner expansion layer 502. The expanded perlite material of the expansion layer 502 will expand rapidly after contacting moisture, and the expanded perlite material will harden after completing the expansion, so that the position between the mounting plate 3 and the connecting plate 2 remains stable.

[0029] The working principle of the above embodiment is:

[0030] (1) First, insert the locking steel pipe columns 1 into the water one by one, and then put the mounting plates 3 into the connecting plates 2 of two adjacent locking steel pipe columns 1, so that the connecting plates 2 are between the mounting plates 3 and the limiting plates 410, and then insert the hexagonal wrench into the hexagonal slot 403, so that the hexagonal wrench drives the rotating block 401 to rotate, and the rotating block 401 drives the connecting rod 405 to rotate, and the connecting rod 405 drives the gear 406 to rotate, and the gear 406 drives the rack 407 to move, and the rack 407 drives the connecting block 408 to move, and the connecting block 408 drives the supporting plate 409 to move, so that the supporting plate 409 fits with the connecting plate 2, so that the position of the mounting plate 3 remains stable.

[0031] (2) After the position of the mounting plate 3 is stabilized, the limit plate 410 can prevent the connection plate 2 from being dislocated. However, there is a gap between the connection plate 2, the limit plate 410 and the mounting plate 3, which may cause loosening. After the mounting plate 3 enters the water, the sponge material of the water-absorbing layer 501 quickly absorbs the water and allows excess water to enter the inner expansion layer 502. The expanded perlite material of the expansion layer 502 will expand rapidly after contacting the water. The expanded expansion layer 502 squeezes the connection plate 2, so that the connection plate 2 and the sealing gasket 503 on the limit plate 410 fit tightly, thereby completing the water-stopping and leak-proofing work. At the same time, the expanded perlite material will harden after the expansion is completed, so that the position between the mounting plate 3 and the connection plate 2 remains stable.
