Description

Technical Field

[0001] The utility model relates to the technical field of joint sealing, in particular to a barrel-type foundation structure joint sealing structure. Background Art

[0002] When using a barrel-type foundation structure for the installation of a workboat dock, there is a gap between the barrel-type foundation structures. In order to prevent the backfill from leaking, it is usually necessary to drive a caulking steel sheet pile and backfill the filter layer material to seal the joints between the barrel-type foundation structures. The width of the existing caulking steel sheet piles is fixed. When sealing different joints, steel sheet piles of corresponding sizes are required, which has poor applicability. Especially when the upper and lower spacing of the joints is uneven, it is difficult to drive the steel sheet piles into the joints, which brings great difficulties to the sealing construction. Summary of the invention

[0003] In view of this, the utility model provides a barrel-type foundation structure joint plugging structure, which can be suitable for plugging joints of different sizes and is simple and convenient to construct.

[0004] The utility model solves the above problems through the following technical means:

[0005] The barrel-type foundation structure joint plugging structure of the utility model is arranged at the joint between two barrel-type foundation structures, and comprises two groups of embedded steel plates arranged at both ends of the splicing side of the barrel-type foundation structure, two groups of tongues and grooves correspondingly arranged and fixed on the embedded steel plates, two arc-shaped steel sheet piles installed at both ends of the joint through the two groups of tongues and grooves, and a crushed stone filter layer arranged in the joint between the two steel sheet piles.

[0006] Preferably, the mortise and tenon is a rectangular groove structure with an opening formed by combining two angle steels fixed relatively vertically on the embedded steel plate.

[0007] As a further improvement of the above technical solution, anti-seepage rubber is provided on both sides of the opening of the mortise and tenon.

[0008] As a further improvement of the above technical solution, stiffening plates are provided on both sides of the mortise and tenon.

[0009] Preferably, the steel sheet pile comprises an arc-shaped plate sealed in the joint, and T-shaped locks provided at both ends of the arc-shaped plate for being engaged and fixed in the mortise and tenon.

[0010] As a further improvement of the above technical solution, a flexible water-stop filling is provided in the mortise and tenon.

[0011] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0012] The barrel-type foundation structure joint plugging structure of the utility model uses two steel sheet piles to plug the two ends of the joint and fill the inner part with a backfill layer, which can effectively prevent the leakage of the backfill soil. The arc-shaped steel sheet piles do not require additional processing during installation and can produce slight bending deformation only when subjected to force, so that they can be used for joint plugging with uneven upper and lower spacing, avoiding the difficulty in installing the plugging sheet piles due to uneven joint spacing.

[0018] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0020] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 to Figure 2As shown: the barrel-type foundation structure joint plugging structure described in this embodiment is arranged at the joint between two barrel-type foundation structures 8, including two groups of embedded steel plates 1 arranged at both ends of the splicing side of the barrel-type foundation structure 8, two groups of correspondingly arranged tongues and grooves 2 fixed on the embedded steel plates 1, two arc-shaped steel sheet piles 3 installed at both ends of the joint through the two groups of tongues and grooves 2, and a crushed stone filter layer 4 arranged in the joint between the two steel sheet piles 3.

[0021] The barrel-type foundation structure joint plugging structure described in this embodiment can effectively prevent leakage of rear blown fill soil by plugging the two ends of the joints with the two steel sheet piles 3 and filling the inner part with a backfill layer 4. The arc-shaped steel sheet piles 3 do not require additional processing during installation and can produce slight bending deformation only by being subjected to force, so that they can be used for plugging joints with uneven upper and lower spacings, avoiding the difficulty in installing the plugging sheet piles due to uneven joint spacings.

[0022] During the caulking construction, firstly, lubricating oil is applied on both sides of the steel sheet pile 3, and then the steel sheet pile 3 is lifted by a crane ship to the position of the mortise and tenon 2 in the joint between the two barrel-type foundation structures 8, and the steel sheet pile 3 is controlled to be in the same straight line with the two mortise and tenon grooves 2 of the same group, and then the steel sheet pile 3 is slowly sunk so that the two ends of the steel sheet pile 3 are inserted into the above-mentioned two mortise and tenon grooves 2 and then slide along the mortise and tenon groove 2. The lubricating oil applied on both sides of the steel sheet pile 3 reduces the frictional resistance between the mortise and tenon groove 2. When the sinking of the steel sheet pile 3 is blocked, a vibration hammer is used to drive the pile to the designed height, and then the second steel sheet pile 3 is driven in the same way, and finally the gravel filter layer 4 is filled in the joint between the two steel sheet piles 3.

[0023] Preferably, Figure 3 As shown, the tongue and groove 2 is a rectangular groove structure with an opening formed by two angle steels fixed relatively vertically on the embedded steel plate 1.

[0024] In order to improve the waterproof effect, as a further improvement of the above technical solution, anti-seepage rubber sheets 5 are provided on both sides of the opening of the mortise and tenon 2, and one end of the two anti-seepage rubber sheets 5 are fixed to the two side surfaces of the opening of the mortise and tenon 2 by bolts, and the other end extends outward and is tightly together, which can seal the connection between the steel sheet pile 3 and the mortise and tenon 2 to prevent other substances from entering from the opening of the mortise and tenon 2, thereby protecting the connection from corrosion and pollution by other substances and extending the service life.

[0025] In order to improve the strength of the mortise and tenon 2 , as a further improvement of the above technical solution, stiffening plates 6 are provided on both sides of the mortise and tenon 2 .

[0026] As a preferred embodiment of this embodiment, Figure 4As shown, the steel sheet pile 3 includes an arc-shaped plate 31 sealed in the joint and T-shaped locking openings 32 provided at both ends of the arc-shaped plate 31 for being engaged and fixed in the mortise and tenon groove 2 .

[0027] As a further improvement of the above technical solution, a flexible water-stopping filler 7 is provided in the mortise and tenon 2, which can not only reinforce both ends of the steel sheet pile 3, but also prevent the mortise and tenon 2 from being corroded by water.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
