Description

Technical Field

[0001] This invention belongs to the field of pile foundation engineering technology, specifically relating to a prefabricated pile clamping structure and its construction method. Background Technology

[0002] Under the national strategy of building a maritime power, marine engineering construction is expanding into offshore deep-water areas, where the marine environment is becoming increasingly harsh. A typhoon season or a large swell means that marine pile foundations must withstand tens of thousands of cycles of low-frequency, high-wave loads in a short period of time. This repetitive and continuous action often causes continuous vibration of the steel pipe piles in the superstructure that have not yet been constructed during the construction phase, leading to damage such as pile foundation fracture, tilting, or collapse, seriously affecting the safety of engineering construction.

[0003] Currently, traditional splicing of clamped piles is generally fixed by welding or bolts. For example, patent document CN110158977A discloses an adjustable steel column connection clamp structure. Its technical solution includes several clamps respectively fitted on each steel column. Two clamps on two adjacent steel columns at the same height are connected by a horizontal telescopic sleeve. Two clamps on two adjacent steel columns located at diagonal positions in the upper and lower rows are connected by an oblique telescopic connecting rod. The specification also discloses that the other end of the inner square tube is respectively fixed with a supporting base plate. The supporting base plate is installed on the second wing plate, and the supporting base plate and the second wing plate are fixedly connected by bolts.

[0004] The above-mentioned technical solution belongs to the field of construction engineering, and the support base plate and the second wing plate are fixedly connected by bolts, making it inconvenient to disassemble, and it cannot be used in marine construction environments. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a prefabricated clamp pile structure and construction method to solve the problems that traditional clamp pile structures usually use bolts for fixing, and the splicing process is relatively cumbersome and inconvenient to disassemble.

[0006] One embodiment of the present invention provides a prefabricated clamped pile structure, comprising:

[0007] Several sets of fixed components;

[0008] A connecting component, which is installed between each group of fixed components;

[0009] The aforementioned fixing components include a left half clamp and a right half clamp;

[0010] The left and right halves of the clamp are fixedly connected, forming a ring-shaped clamp after they are fixedly connected.

[0011] The connecting assembly includes several sleeves, connecting rods, and locking components;

[0012] Several of the sleeves are fixedly arranged in a ring array on the ring clamp, and the sleeves are provided with through holes adapted to the plunger;

[0013] One end of the connecting rod is a splicing end, and the other end is a sleeve end. The sleeve end is fixedly mounted on each sleeve by a locking assembly.

[0014] The locking assembly includes a water tank, several cylinders, a compression spring, and a plunger;

[0015] The water tank is installed inside the connecting rod;

[0016] Several of the aforementioned cylinders are symmetrically installed on the water tank with the connecting rod as the central axis and are connected to the inside of the water tank;

[0017] The compression spring is disposed inside the cylinder body, and one end of the compression spring is fixedly disposed on the cylinder body, the other end of the compression spring is fixedly disposed on the plunger, and the plunger is movably disposed inside the cylinder body and extends out of the cylinder body;

[0018] The fixing component is used to fit onto the pile body to fix the pile body in place;

[0019] The connecting component is used to connect each group of fixed components;

[0020] The annular clamp is fitted with a rubber pad, which is used to enhance the friction between the annular clamp and the pile body.

[0021] This invention provides a prefabricated pile clamping structure. The left and right halves of the clamp form an integral annular clamp. A rubber pad is installed on the inner wall of the clamp, which secures the annular clamp to the pile body. The clamps are assembled according to the required quantity. After confirming the number of clamps to be assembled, a connecting rod of suitable length is selected based on the pile spacing. The connecting rod is inserted into the sleeve and fixed by a locking assembly and the sleeve. Connecting rings are used to assemble each set of annular clamps with the connecting rod installed sequentially. After assembly, the structure is hoisted. This effectively solves the problems of traditional pile clamping structures, which typically use bolts for splicing, and the cumbersome and inconvenient disassembly process.

[0022] In one embodiment, the fixing component further includes a lug;

[0023] The lifting lugs are symmetrically arranged on the annular clamp;

[0024] The lifting lug is moved by an external hoisting machine to move the ring clamp.

[0025] In one embodiment, the connection component further includes a connection ring;

[0026] The connecting ring is threaded onto the splicing end of the connecting rod;

[0027] The connecting ring is used to fix the splicing ends of two connecting rods together, thereby splicing several sets of ring clamps.

[0028] The plunger moves into the through hole after being driven by the compression spring, thereby connecting the connecting rod and the annular clamp.

[0029] In one embodiment, the locking assembly further includes a water inlet hole and a water outlet hole;

[0030] The water injection hole is located on the top of the water tank and is used to connect an external water pipe for water injection. The external water pipe is equipped with a valve for controlling the water flow.

[0031] The water outlet is located at the bottom of the water tank and is used to connect an external water pipe for drainage. The external water pipe is equipped with a valve for controlling the water flow.

[0032] In one embodiment, the interior of the cylinder is a hollow structure;

[0033] The compression spring is used to control the movement of the plunger between a first position and a second position. The first position is when the plunger is subjected to water pressure and passes through the through hole of the sleeve, and the compression spring is in a stretched state. The second position is when the plunger is disengaged from the through hole of the sleeve, and the compression spring is in a free length state or a compressed state.

[0034] In one embodiment, several of the annular clamps are interconnected by connecting rods to form a pile clamping structure;

[0035] The pile clamping structure is used to fix multiple piles.

[0036] One embodiment of the present invention provides a construction method for a prefabricated pile clamp structure, comprising:

[0037] The prefabricated pile clamping structure as described in any of the above embodiments, and

[0038] Step 1: Assemble the ring clamp by combining the left and right halves. Set rubber pads on the inner wall of the ring clamp to fix the ring clamp to the pile body. Assemble the clamps according to the actual required number. After confirming the number of clamps to be assembled, select a connecting rod of appropriate length according to the pile spacing.

[0039] Step 2: Insert the connecting rod into the sleeve, then inject external water into the water tank through the water inlet. The water pressure pushes the plunger and causes the compression spring to stretch. The plunger moves into the matching through hole on the sleeve, thus fixing the connecting rod and the sleeve.

[0040] Step 3: Use connecting rings to assemble each set of ring clamps with the connecting rods installed. After assembly, a clamping pile structure is formed. Use an external crane to lift the assembled clamping pile structure and fit it onto the designated pile body, lock it in place, and finally remove the lifting equipment.

[0041] The prefabricated pile clamping structure and construction method provided in the above embodiments have the following characteristics:

[0042] Beneficial effects:

[0043] 1. The left and right halves of the clamp form an integral ring clamp. A rubber pad is installed on the inner wall of the clamp, which fixes the ring clamp to the pile body. The clamps are assembled according to the actual required quantity. After confirming the number of clamps to be assembled, a connecting rod of appropriate length is selected according to the pile spacing. The connecting rod is inserted into the sleeve, and then external water is injected into the water tank through the water inlet. The water pressure pushes the plunger and drives the compression spring to move. The plunger moves into the matching through hole on the sleeve, thereby fixing the connecting rod and the sleeve. The connecting ring is assembled with the connecting rod installed in each group in sequence using a connecting ring. After assembly, it is hoisted. This method effectively solves the problem that traditional pile clamping structures usually use bolts for fixing, and the splicing process is relatively cumbersome and inconvenient to disassemble.

[0044] 2. Connect the ring clamps with the connecting rods installed on each set to the connecting ring. Threaded connection is used because it is simple and convenient. The connection length of the connecting rod can be changed by the depth of the thread connection between the connecting ring and the connecting rod, which makes it easy to adjust the length of the two connecting rods after connection. When disassembling the connecting ring, you only need to unscrew the connecting ring.

[0045] 3. When disassembling the connecting rod, simply drain the water from the tank through the outlet. After the plunger is depressurized, it is pulled back by the contraction force of the compression spring, thus making it easy to disassemble the connecting rod. The clamp-like structure of this invention is used in offshore operations. When operating at sea for a long time, it is easy to encounter danger. After draining the water through the drain hole, the connecting rod can be pulled out, which greatly improves the disassembly speed. Attached Figure Description

[0061] Please see Figure 1-10 As shown, one embodiment of the present invention provides a prefabricated clamped pile structure, comprising:

[0062] Several sets of fixed components 1;

[0063] Connection component 3 is installed between each group of fixed components 1;

[0064] The set of fixing components 1 includes a left half clamp 101 and a right half clamp 102;

[0065] The left half clamp 101 and the right half clamp 102 are fixedly connected, and the left half clamp 101 and the right half clamp 102 form a ring clamp after being fixedly connected;

[0066] The connecting assembly 3 includes a plurality of sleeves 301, connecting rods 302 and locking assemblies 303;

[0067] A plurality of sleeves 301 are fixedly arranged in a ring array on the ring clamp, and the sleeves 301 are provided with through holes 4 that are adapted to the plunger 3035;

[0068] One end of the connecting rod 302 is a splicing end, and the other end is a sleeve end. The sleeve end is fixedly mounted on each sleeve 301 by a locking assembly 303.

[0069] The locking assembly 303 includes a water tank 3031, several cylinders 3033, a compression spring 3034, and a plunger 3035;

[0070] The water tank 3031 is installed inside the connecting rod 302;

[0071] Several cylindrical bodies 3033 are symmetrically installed on the water tank 3031 with the connecting rod 302 as the central axis and are connected to the interior of the water tank 3031;

[0072] The compression spring 3034 is disposed inside the cylinder 3033, and one end of the compression spring 3034 is fixedly disposed on the cylinder 3033, and the other end of the compression spring 3034 is fixedly disposed on the plunger 3035, and the plunger 3035 is movably disposed inside the cylinder 3033 and extends out of the cylinder 3033.

[0073] The fixing component 1 is used to be sleeved on the pile body to fix the pile body;

[0074] The connecting component 3 is used to connect each group of fixed components 1;

[0075] The annular clamp is fitted with a rubber pad 2, which is used to enhance the friction between the annular clamp and the pile body.

[0076] The present invention provides a prefabricated pile clamping structure in which the left half clamp 101 and the right half clamp 102 form an integral annular clamp. A rubber pad 2 is provided on the inner wall of the clamp. When the left half clamp 101 and the right half clamp 102 are tightened with bolts, the rubber pad 2 is firmly fixed to the pile, increasing friction and thus better securing the annular clamp to the pile, thereby enhancing the stability of the pile. The clamps are then assembled according to the actual required quantity. After confirming the number of clamps to be assembled, a connecting rod 302 of appropriate length is selected based on the pile spacing and inserted into the sleeve 301. The 01 are arranged in a ring array on each sleeve 301. The ring array can be three, four or n. In this invention, the preferred number of sleeves 301 is four. The connecting rod 302 can be well fixed to the sleeve 301 by the locking component. The connecting rod 302 is fixed to the sleeve 301 by the locking component. The ring clamps with the connecting rod 302 installed in each group are assembled in sequence using the connecting ring 304. After assembly, the hoisting is carried out. This solves the problem that the traditional clamp pile structure usually uses bolts for fixing, and the splicing process is relatively cumbersome and inconvenient to disassemble.

[0077] In one embodiment, the fixing component 1 further includes a lug 103;

[0078] The lifting lugs 103 are symmetrically arranged on the annular clamp;

[0079] Specifically, the lifting lug 103 can be lifted and moved to the pile body that needs to be fixed by an external hoisting machine.

[0080] The lifting lug 103 is moved by an external hoisting machine to move the ring clamp.

[0081] In one embodiment, the connection component 3 further includes a connection ring 304;

[0082] The connecting ring 304 is threaded onto the splicing end of the connecting rod 302;

[0083] The connecting ring 304 is used to fix the splicing ends of the two connecting rods 302 together, thereby splicing several sets of annular clamps.

[0084] The plunger 3035 moves into the through hole 4 after being driven by the compression spring 3034, thereby connecting the connecting rod 302 and the annular clamp.

[0085] Specifically, the connecting ring 304 connects to the annular clamps of each set of connected rods 302. Threaded connection is used because it is simple and convenient, and the connection length of the connected rods 302 can be changed by the depth of the threaded connection between the connecting ring 304 and the connected rods 302, making it easy to adjust the length of the two connected rods 302 after connection.

[0086] In one embodiment, the locking assembly 303 further includes a water inlet 3032 and a water outlet 3036;

[0087] The water injection hole 3032 is located on the top of the water tank 3031 and is used to connect an external water pipe for water injection. The external water pipe is equipped with a valve for controlling the water flow.

[0088] The water outlet 3036 is located at the bottom of the water tank 3031 and is used to connect an external water pipe for drainage. The external water pipe is equipped with a valve for controlling the water flow.

[0089] Specifically, external water is injected into the water tank 3031 through the water inlet 3032. The water pressure pushes the plunger 3035 to move. When the external water is introduced into the water tank 3031, water pipes are connected to the water inlet 3032 and the water outlet 3036. Generally, there is a valve on the water pipe to control the water flow. The valve controls the water flow in and out. After water is injected, the water inlet 3032 and the water outlet 3036 are sealed with plugs.

[0090] In one embodiment, the interior of the cylindrical body 3033 is a hollow structure;

[0091] The compression spring 3034 is used to control the movement of the plunger 3035 between a first position and a second position. The first position is when the plunger 3035 is subjected to water pressure and passes through the through hole 4 of the sleeve 301, and the compression spring 3034 is in a stretched state. The second position is when the plunger 3035 is disengaged from the through hole 4 of the sleeve 301, and the compression spring 3034 is in a free length state or a compressed state.

[0092] Several of the aforementioned annular clamps are interconnected by connecting rods 302 to form a pile clamping structure;

[0093] The pile clamping structure is used to fix multiple piles.

[0094] Specifically, when disassembling the connecting rod 302, simply drain the water from the water tank 3031 through the outlet 3036. After the water pressure is gone, the plunger 3035 is pulled back by the contraction force of the compression spring 3034, which makes it easy to disassemble the connecting rod 302. Then loosen the connecting ring 304 to separate the two connecting rods 302.

[0095] One embodiment of the present invention provides a construction method for a prefabricated pile clamp structure, comprising:

[0096] The prefabricated pile clamping structure as described in any of the above embodiments, and

[0097] Step 1: The left half of the clamp 101 and the right half of the clamp 102 form an integral ring clamp. Rubber pads 2 are set on the inner wall of the ring clamp. The ring clamp is fixed to the pile body by the rubber pads 2. Assemble the clamps according to the actual required quantity. After confirming the number of clamps to be assembled, select a connecting rod 302 of appropriate length according to the pile spacing.

[0098] Step 2: Insert the connecting rod 302 into the sleeve 301, and then inject external water into the water tank 3031 through the water inlet. The water pressure pushes the plunger 3035 and drives the tension spring 3034 to stretch. The plunger 3035 moves into the matching through hole 4 on the sleeve 301, thereby fixing the connecting rod 302 and the sleeve 301.

[0099] Step 3: Use connecting ring 304 to assemble each set of ring clamps with connecting rod 302 installed through connecting ring 304. After assembly, a clamping pile structure is formed. Use an external crane to lift the assembled clamping pile structure and put it into the designated pile body, lock it in place, and finally remove the lifting equipment.
