The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as limiting the present application.

[0041] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the applicability of other processes and / or the use of other materials.

[0042] A steel pipe pile underwater flat connection construction device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0043] As shown in Figures 1-8 , the steel pipe pile underwater flat connection construction device according to the embodiment of the first aspect of the present application comprises a buoy 20, a flat connection assembly 30 and a locking piece 40.

[0044] The buoy 20 has an accommodating cavity 201 for accommodating a medium, the buoy 20 is used in sliding fit with the steel pipe pile 10, the buoy 20 has a first position and a second position, the buoy 20 switches between the first position and the second position, the first position is the position of the buoy 20 when the buoy 20 does not accommodate the medium, and the second position is the position of the buoy 20 when the buoy 20 accommodates a medium of a preset volume.

[0045] The flat link assembly 30 is connected to the buoy 20.

[0046] The locking member 40 has a locking state and an unlocking state, when the locking member 40 is in the locking state, the locking member 40 locks the buoy 20 in the first position and / or the second position on the steel pipe pile 10, when the locking member 40 is in the unlocking state, the buoy 20 and the steel pipe pile 10 are in a sliding fit.

[0047] It should be noted that the medium can be water, sand or other suitable substances, and the present embodiment does not limit this.

[0048] In actual application, the steel pipe pile 10 is inserted into a river, lake or sea. The buoy 20 without containing the medium can float on the water surface at the current time because the gravity received by the buoy 20 is less than the buoyancy received by the buoy 20, and the buoy 20 with containing the medium can sink to the preset depth at the current time because the gravity received by the buoy 20 is greater than the buoyancy received by the buoy 20.

[0049] It can be understood that the volume of the medium determines the sinking depth of the buoy 20, so the skilled in the art sets the volume value of the medium according to the requirement to make the buoy 20 sink to the preset depth. Therefore, the present embodiment does not limit the setting of the second position.

[0050] It should be noted that the medium can be introduced into the buoy 20 by means of a tool, for example, when the medium is water, the tool can be a pump, and the water is introduced into the buoy 20 by the pump; or when the medium is sand, the tool can be a conveyor belt, and the sand is introduced into the buoy 20 by the conveyor belt.

[0051] The buoy 20 is used to be in a sliding fit with the steel pipe pile 10, that is, the buoy 20 can slide along the axial direction of the steel pipe pile 10. As known from the above, the buoy 20 can slide along the steel pipe pile 10 according to the volume of the medium in the buoy 20, and the buoy 20 can switch between the first position and the second position.

[0052] The flat link assembly 30 is connected to the buoy 20. In this way, the flat link assembly 30 is connected to the buoy 20 as a whole, and the buoy 20 drives the flat link assembly 30 to slide along the axial direction of the steel pipe pile 10. Further, the flat link assembly 30 can switch between the third position and the fourth position, the third position being the position of the flat link assembly 30 when the buoy 20 is in the first position, and the fourth position being the position of the flat link assembly 30 when the buoy 20 is in the second position.

[0053] The locking member 40 can be a plug, and the plug is arranged on the buoy 20, and a plurality of plug holes are arranged on the outer surface of the steel pipe pile 10 in the axial direction of the steel pipe pile 10. When the buoy 20 is in the first position or the second position, the plug is plugged and matched with the plug hole, that is, at the current moment, the plug is in the locked state; when the buoy 20 is between the first position and the second position, the plug is separated from the plug hole, that is, at the current moment, the plug is in the unlocked state.

[0054] Of course, the locking member 40 can also be in other suitable forms, which are not enumerated and described in the embodiment.

[0055] As can be known from the above, by switching the buoy 20 between the first position and the second position, the flat connection assembly 30 is connected to the buoy 20, which avoids underwater construction of the flat connection assembly 30, greatly reduces the construction difficulty of the underwater flat connection assembly 30, and does not need to invest in large hoisting equipment; avoids the increase of the cost of steel materials, and greatly reduces the construction cost.

[0056] It can be understood that preferably, the medium is water, which is locally available and convenient to pump. In the related art, the flat connection assembly is sent to the preset depth by the traction member, and the present application can be directly pumped by the pump, which avoids manual operation, and the pump pumping time is controlled to make the buoy 20 sink to the preset depth, which completely realizes automatic operation and greatly reduces the labor intensity of the operator. In addition, the medium is locally available, which is convenient and saves cost, and is helpful to reduce the construction cost.

[0057] In some embodiments of the present application, as shown in Figure 1 The buoy 20 is arranged on the steel pipe pile 10. In this way, the steel pipe pile 10 has a guiding effect on the movement of the buoy 20, which helps the buoy 20 to accurately switch between the first position and the second position.

[0058] Specifically, the buoy 20 is provided with a through hole which is matched with the steel pipe pile 10. The buoy 20 can be a cylindrical body, the buoy 20 can be a regular prism, and the buoy 20 can be in other suitable shapes, which are not limited in the embodiment.

[0059] As shown in Figure 1 Preferably, the buoy 20 is a cylindrical body, which is convenient to process and has low manufacturing cost.

[0060] Of course, it can be understood that the buoy 20 and the steel pipe pile 10 can have other setting modes, which are not limited in the embodiment.

[0061] Further, the inner surface of the buoy 20 is provided with a corrosion-resistant layer. For example, the buoy 20 can be made of stainless steel material, and the inner surface of the buoy 20 is coated with rust-proof paint. Those skilled in the art can select appropriate materials according to the needs, which are not limited in the embodiment.

[0062] In this way, the medium can avoid corroding the buoy 20, and the service life of the buoy 20 is prolonged.

[0063] It should be noted that the buoy 20 can be subjected to a sealing test to ensure that the buoy 20 has good sealing performance.

[0064] In some embodiments of the present application, the buoy 20 is provided with at least one connecting pipe 22, the connecting pipe 22 is in communication with the accommodating cavity 201, the accommodating cavity 201 has a bottom, and there is a preset distance d between the end of the connecting pipe 22 facing the bottom and the bottom, 10 cm≤d≤40 cm.

[0065] Specifically, as shown in Figure 4 The buoy 20 includes a cylinder 21 and a connecting pipe 22, the cylinder 21 includes a bottom and a cylinder wall surrounding the bottom, and the bottom is horizontally arranged. The connecting pipe 22 is connected to the cylinder wall.

[0066] Since the medium in the buoy 20 is lake water, river water, seawater, or river water, and the medium contains sand, the bottom of the buoy 20 can deposit a large amount of sand.

[0067] Therefore, there is a preset distance d between the end of the connecting pipe 22 facing the bottom and the bottom, 10 cm≤d≤40 cm. Preferably, d=30 cm. In this way, the end of the connecting pipe 22 facing the bottom is prevented from being buried by sand.

[0068] Further, the bottom of the cylinder 21 is inclined in the vertical direction, as shown in Figure 4 This arrangement is conducive to the deposition of sand to the preset position of the bottom and is more conducive to preventing the end of the connecting pipe 22 facing the bottom from being buried by sand.

[0069] Further, as shown in Figure 4 The end of the connecting pipe 22 away from the bottom extends out of the buoy 20, and the length of the part of the connecting pipe 22 extending out of the buoy 20 is a preset length, so that when the buoy 20 is in the second position, the end of the connecting pipe 22 away from the bottom is higher than the water surface. In this way, the volume of the medium entering the buoy 20 can be accurately controlled, and accidental entry of the medium into the buoy 20 is avoided.

[0070] Further, the end of the connecting pipe 22 away from the bottom is provided with a cover, and the cover covers the opening of the end of the connecting pipe 22 away from the bottom. In this way, after the medium is filled in the buoy 20, the cover makes the accommodating cavity 201 sealed, air is prevented from entering the buoy 20, and the corrosion of the inner surface of the buoy 20 by air is reduced.

[0071] Further, as shown in Figure 4As shown, the end of the connecting pipe 22 away from the bottom is provided with an exhaust port 221. In this way, the water pumped into the buoy 20 is facilitated.

[0072] In some embodiments, the flat link assembly 30 comprises a plurality of pipes, at least part of the pipes are provided with cavities for accommodating the medium. In this way, by increasing the mass of the flat link assembly 30, the overall sinking of the flat link assembly 30 and the buoy 20 is facilitated, and the overall sinking speed of the flat link assembly 30 and the buoy 20 is improved.

[0073] In specific embodiments, as shown in Figure 3 and Figure 4 The plurality of steel pipe piles 10 are arranged in a rectangular array. The flat link assembly 30 comprises a plurality of first flat links 31 and a plurality of second flat links 32. The first flat link 31 comprises a first pipe 311, a plurality of partitions 312, and a plurality of water injection pipes 313.

[0074] Any two adjacent steel pipe piles 10 are provided with two first pipes 311 arranged vertically. The first pipe 311 is arranged horizontally. The first pipe 311 is connected to the buoy 20 on the steel pipe pile 10.

[0075] Between the two first pipes 311 arranged vertically, a plurality of second flat links 32 are arranged, and the second flat link 32 connects the two first pipes 311. The second flat link 32 can be a second pipe, a rod, an H-shaped steel, etc.

[0076] The first pipe 311 is a hollow structure, and a plurality of partitions 312 are arranged in the first pipe 311 along the axis direction of the first pipe 311 to form a plurality of first cavities 301 in the first pipe 311. Each first cavity 301 is provided with a water injection pipe 313, and the water injection pipe 313 is in communication with the first cavity 301. Water is injected into the first cavity 301 through the pump body.

[0077] Further, the surface of the partition 312 and the inner surface of the first pipe 311 are provided with a corrosion-resistant layer. In this way, the corrosion of the partition 312 and the first pipe 311 by water can be avoided, and the service life of the first pipe 311 and the partition 312 can be prolonged.

[0078] It should be noted that the first cavity 301 can be subjected to a sealing test to ensure that the first cavity 301 has good sealing performance.

[0079] Further, when the buoy 20 is in the second position, the end of the water injection pipe 313 is higher than the water surface. In this way, the volume of the medium entering the first cavity 301 can be accurately controlled, and the medium can be prevented from accidentally entering the first cavity 301.

[0080] Further, the end of the water injection pipe 313 is provided with a cover, and the cover covers the opening at the end of the water injection pipe 313. In this way, after the medium is filled in the first cavity 301, the cover seals the first cavity 301, so that air cannot enter the first pipe 311, and the corrosion of the inner surface of the first pipe 311 and the baffle 312 by air is reduced.

[0081] Further, referring to Figure 3 Fig. 2, the first pipe 311 is connected to the float 20 through a sleeve pipe (not shown).

[0082] It should be noted that one end of the first pipe 311 is provided with a sleeve pipe, and the other end is provided with another sleeve pipe. The first pipe 311 is connected to the float 20 through the sleeve pipe. In this way, the spacing between the steel pipe piles 10 can be fine-tuned.

[0083] Of course, it can be understood that one end of the first pipe 311 can be provided with a sleeve pipe, and the other end can not be provided.

[0084] In some embodiments, the locking member 40 includes a clamp member, and the float 20 is locked and connected to the steel pipe pile 10 through the clamp member.

[0085] Specifically, as Figure 2 shown in Fig. 3, the clamp member includes a first part 41 and a second part 42, and the first part 41 and the second part 42 are connected through bolts. When the first position and the second position are switched, the bolts are loosened, and the float 20 can move along the steel pipe pile 10, so that the float 20 can be switched from the first position to the second position. When the first position or the second position is reached, the bolts are tightened, so that the float 20 is fixedly connected to the steel pipe pile 10.

[0086] In this way, the steel pipe pile 10 or the float 20 is not processed, and the steel pipe pile 10 or the float 20 is not locally damaged.

[0087] Further, the clamp member is arranged at the upper end of the float 20.

[0088] It should be noted that when the length of the float 20 is designed to be long, the float 20 is in the second position, the upper end of the float 20 does not fall below the water surface, and the horizontal connection assembly 30 is at a predetermined depth under water. The operator can perform the fixed connection between the float 20 and the steel pipe pile 10 on the water surface, which is convenient to operate.

At the current time, the first position of the float 20 can be a position where the float 20 is higher than the water surface, or a position where the float 20 floats on the water surface. A person skilled in the art sets the first position according to the needs. This is helpful for the operator to operate the float 20.
