Description

Technical Field

[0001] This invention relates to an adjustable construction positioning frame for combined steel pipe piles and its construction method, belonging to the field of steel pipe pile construction equipment. Background Technology

[0002] Precast concrete (PC) composite steel pipe piles are all-steel retaining structures formed by interlocking steel pipe piles and Larssen sheet piles. In recent years, they have been widely used in foundation pit projects due to their maintenance-free and environmentally friendly nature. The steel pipe piles and Larssen sheet piles in PC pile construction are connected by interlocking mechanisms; therefore, accurate positioning and verticality must be ensured during construction. Otherwise, problems such as interlocking failure or splitting of the interlocking mechanisms may occur, affecting construction efficiency and even causing issues with the watertightness and structural safety of the retaining structure.

[0003] However, current methods for constructing PC (precast concrete) piles still rely on manual marking and positioning, as well as manually adjusting the verticality of the pile before driving. This results in significant limitations in pile positioning accuracy and verticality due to manual operation, and also leads to low construction efficiency. Therefore, there is an urgent need to invent an adjustable construction positioning frame for combined steel pipe piles to solve these problems. Summary of the Invention

[0004] This invention provides an adjustable construction positioning frame for combined steel pipe piles and its construction method, aiming to solve technical problems such as low positioning accuracy, low construction efficiency, and large manual operation errors in the construction process of combined steel pipe piles.

[0005] To solve the above technical problems, the present invention includes the following technical solutions:

[0006] Two steel pipe piles and one Larssen sheet pile in the middle are connected by interlocking to form a composite structure; an adjustable construction positioning frame for the composite steel pipe pile is used for vertical positioning of the composite structure;

[0007] The adjustable construction positioning frame includes a first-layer positioning frame, a second-layer positioning frame, and a column. The first-layer positioning frame and the second-layer positioning frame are arranged at intervals and fixed by the column to form a double-layer frame structure.

[0008] Both the first-layer positioning frame and the second-layer positioning frame include a rectangular frame, and two first telescopic guide rail assemblies, two second telescopic guide rail assemblies, four first positioning components, and two second positioning components disposed within the rectangular frame;

[0009] Two first telescopic guide rail assemblies are respectively disposed on the inner sides of the two long sides of the rectangular frame. Each first telescopic guide rail assembly includes one first automatic telescopic device, two second automatic telescopic devices, and two guide rail rods. A guide rail rod is disposed at each end of the first automatic telescopic device, and a second automatic telescopic device is fixedly disposed on each guide rail rod. The first automatic telescopic device can adjust the two guide rail rods to extend or retract synchronously, so that the position of the second automatic telescopic device is directly opposite the steel pipe pile. A first slider is disposed on the guide rail rods at both ends of the second automatic telescopic device, and the second automatic telescopic device can drive the two first sliders to move closer or further away.

[0010] Two second telescopic guide rail assemblies are respectively set on the inner side of the two short sides of the rectangular frame; the second telescopic guide rail assembly includes a third automatic telescopic device and two guide rail rods. A guide rail rod is set at each end of the third automatic telescopic device, and a second slider is set on each guide rail rod at both ends of the third automatic telescopic device. The third automatic telescopic device can adjust the distance between the two second sliders.

[0011] Both the first positioning component and the second positioning component include an X-shaped extension arm adjusting rod, with rollers at each of the two ends of one end of the X-shaped extension arm adjusting rod; the two ends of the other end of the X-shaped extension arm adjusting rod of the first positioning component are hinged to the first sliders at both ends of the second automatic expansion joint; the two ends of the other end of the X-shaped extension arm adjusting rod of the second positioning component are hinged to the second sliders at both ends of the third automatic expansion joint; the rollers of the first positioning component and the second positioning component are used to position the steel pipe pile.

[0012] Furthermore, the rectangular frames of the first and second positioning frames each include four L-shaped components, which are located at the four corners of the rectangle, and the ends of two adjacent L-shaped components are sleeved and fixed.

[0013] The socket is equipped with a telescopic hydraulic rod and a locking device. The length and width of the rectangular frame can be adjusted by extending and retracting the telescopic hydraulic rod, and the locking device can lock the socket of the rectangular frame after adjustment.

[0014] Furthermore, the bottom of the column is equipped with wheels, which enable the adjustable construction positioning frame of the combined steel pipe pile to move horizontally, and the wheels are equipped with brake pads.

[0015] Furthermore, the adjustable construction positioning frame is connected to an external automated control station;

[0016] The automated control station controls the operation of the first, second, and third automatic expansion joints.

[0017] Accordingly, the present invention also provides a construction method for the adjustable construction positioning frame for the combined steel pipe pile, comprising the following steps:

[0018] Step 1: Set the adjustable construction positioning frame in the predetermined position and connect it to the external automated control station;

[0019] Step 2: Connect the steel pipe piles and Larssen sheet piles with interlocking to form a composite. Use a lifting device to lift the composite and insert the bottom of the composite into the rectangular frame of the first and second positioning frames. The first and third automatic expansion joints are facing the Larssen sheet piles.

[0020] Step 3: Control the extension and retraction of the first automatic expansion joint through the automated control station, so that the second automatic expansion joints on both sides of the first automatic expansion joint are directly facing the steel pipe pile;

[0021] Step 4: Control the extension and retraction of the second and third automatic expansion joints through the automated control station, adjust the angle between the X-shaped extension arm adjusting rods of the first and second positioning components to make the rollers contact the steel pipe pile and hug the steel pipe pile, adjust the verticality of the assembly through the first and second positioning frames, and then press the assembly into the soil.

[0022] The present invention, by adopting the above technical solutions, has the following advantages and positive effects compared with the prior art: The adjustable construction positioning frame for combined steel pipe piles provided by the present invention, combined with an automated control station, can adjust the position of the second automatic expansion joint through the first automatic expansion joint, so that the second automatic expansion joint is directly facing the steel pipe pile. Then, the angle of the X-shaped extension arm adjusting rod is adjusted through the second and third automatic expansion joints to encircle the steel pipe pile. Each steel pipe pile is positioned by three sets of X-shaped extension arm adjusting rods, which can realize intelligent and precise positioning of combined steel pipe piles with different cross-sectional dimensions. The adjustable construction positioning frame adopts a double-layer frame structure. The first and second positioning frames work together, which not only has a more stable structure, but also can control the verticality of the steel pipe piles. This positioning frame improves construction efficiency and construction quality by driving the combined steel pipe pile and Larssen steel sheet pile into the soil together. Therefore, the present invention can solve the technical problems of low positioning accuracy, low construction efficiency, and large human operation error in the construction of combined steel pipe piles.

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the adjustable construction positioning frame for combined steel pipe piles and its construction method provided by the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0038] Example 1

[0039] Combination Figure 1 and Figure 2 As shown, two steel pipe piles 1 and a Larssen steel sheet pile 2 located in the middle are connected by a locking mechanism to form a composite body. The positioning frame is used to vertically position the composite body, and then the power mechanism is used to press the composite body into the soil together, thereby improving construction efficiency and construction quality.

[0040] Combination Figure 1 and Figure 2As shown, the adjustable construction positioning frame for combined steel pipe piles includes a first-layer positioning frame 100, a second-layer positioning frame 101, and a column 102. The first-layer positioning frame 100 and the second-layer positioning frame 101 are arranged at intervals and fixed by the column 102 to form a double-layer frame structure.

[0041] Combination Figures 1 to 3 As shown, both the first-layer positioning frame 100 and the second-layer positioning frame 101 include a rectangular frame 110, two first telescopic guide rail assemblies 120, two second telescopic guide rail assemblies 130, four first positioning components 140, and two second positioning components 150.

[0042] Two first telescopic guide rail assemblies 120 are respectively arranged along the inner side of the long side of the rectangular frame 110. Each first telescopic guide rail assembly 120 includes one first automatic telescopic device 121, two second automatic telescopic devices 122, and two guide rail rods 123. A guide rail rod 123 is respectively provided at both ends of the first automatic telescopic device 121, and a second automatic telescopic device 122 is fixedly mounted on each guide rail rod 123. The first automatic telescopic device 121 can adjust the movement of the two guide rail rods 123 toward or away from the first automatic telescopic device 121, thereby adjusting the combined length of the guide rail rods and the first automatic telescopic device 121. The positions of the two second automatic telescopic devices 122 change as the guide rail rods 123 move. First sliders 124 are provided on the guide rail rods located at both ends of the second automatic telescopic devices 122, and the second automatic telescopic devices 122 are used to adjust the distance between the two first sliders 124.

[0043] Two second telescopic guide rail assemblies 130 are respectively arranged along the inner side of the short side of the rectangular frame 110. The second telescopic guide rail assembly 130 includes a third automatic telescopic device 131 and two guide rail rods 132. A guide rail rod 132 is respectively arranged at both ends of the third automatic telescopic device 131, and a second slider 133 is respectively arranged on the guide rail rods 132 at both ends of the third automatic telescopic device 131. The third automatic telescopic device 131 can adjust the two guide rail rods to face or move away from the third automatic telescopic device 131, thereby adjusting the distance between the two second sliders 133.

[0044] Both the first positioning component 140 and the second positioning component 150 include an X-shaped extension arm adjusting rod 141, with rollers 142 respectively provided at the two ends of the same end of the X-shaped extension arm adjusting rod 141; the two ends of the other end of the X-shaped extension arm adjusting rod 141 of the first positioning component 140 are respectively hinged to the first sliders 124 at both ends of the second automatic telescopic device 122; the two ends of the other end of the X-shaped extension arm adjusting rod of the second positioning component 150 are respectively hinged to the second sliders 133 at both ends of the third automatic telescopic device 131.

[0045] Two steel pipe piles and a Larssen sheet pile in the middle form a combination. The first automatic expansion joint 121 is positioned directly opposite the Larssen sheet pile, and the third automatic expansion joint 131 is positioned directly opposite the steel pipe pile. The first automatic expansion joint 121 adjusts the guide rails on both sides so that the second automatic expansion joint 122 is positioned directly opposite the steel pipe pile. By adjusting the position of the first slider 124 through the second automatic expansion joint 122, the included angle of the X-shaped extension arm adjusting rod of the first positioning component 140 is changed, so that the two end rollers clamp the steel pipe pile. By adjusting the position of the second slider 133 through the third automatic expansion joint 131, the included angle of the X-shaped extension arm adjusting rod of the second positioning component 150 is changed, so that the two end rollers clamp the steel pipe pile. Therefore, the four rollers of the two first positioning components 140 and the two rollers of the one second positioning component 150 position the same steel pipe pile, enabling precise positioning of the steel pipe pile. The angle of the X-shaped extension arm adjusting rod can be adjusted by the second automatic expansion joint 122 and the third automatic expansion joint 131, and the angle is infinitely adjustable, enabling the adjustable construction positioning frame for combined steel pipe piles to be applied to steel pipe piles of different diameters, thus improving the adaptability of the positioning frame. For example, Figure 3 When the cross-section of the steel pipe pile is large (such as φ750mm), the included angle of the X-shaped outrigger adjusting rod is 120 degrees. Figure 4 When the cross-section of the steel pipe pile is small (e.g., φ630mm), the included angle of the X-shaped extension arm adjusting rod changes from 120 degrees to 100 degrees. Larssen sheet piles vary in size and width; the first automatic expansion joint 121 can adjust the distance between the two second automatic expansion joints 122 to match Larssen sheet piles of different widths.

[0046] The first automatic expansion joint 121, the second automatic expansion joint 122, and the third automatic expansion joint 131 all employ high-torque expansion joints made of high-strength alloy steel. The automatic expansion joints can utilize bidirectional hydraulic cylinders with bidirectional hydraulic telescopic rods. These rods connect to guide rails or the first slider 124 or the second slider 133, and the extension and retraction of the rods are controlled by the hydraulic cylinders to adjust the guide rails. For example, the automatic expansion joints can incorporate a hydraulic adjustment and locking system. This system includes a hydraulic actuator, a locking block, and a pressure feedback device. The hydraulic actuator provides the extension and retraction power, the locking block stabilizes the overall structure, and the pressure feedback device provides pressure data. Alternatively, a double-threaded sleeve can be used for extension and retraction. The rotation of the double-threaded sleeve causes the threaded rods at both ends to screw in and out, achieving length adjustment.

[0047] In one specific embodiment, the rectangular frames 110 of both the first-layer positioning frame 100 and the second-layer positioning frame 101 include four L-shaped components. These four L-shaped components are located at the four corners of the rectangle, and the ends of adjacent L-shaped components are sleeved and fixed. By adjusting the insertion depth of the insertion part, the length and width of the rectangular frame 110 can be adjusted, thereby enabling the adjustable construction positioning frame for combined steel pipe piles to adapt to a wider range of sizes, further improving the applicability of the adjustable construction positioning frame for combined steel pipe piles. For example, a telescopic hydraulic rod and a locking device are provided inside the sleeve, and the size of the rectangular frame is changed by adjusting the telescopic hydraulic rod. Triangular reinforcing plates are provided at the right angles of the L-shaped components, increasing the overall stability of the frame.

[0048] In one specific embodiment, a traveling wheel is provided below the second-layer positioning frame 101 or below the column 102, thereby forming a movable double-layer frame structure. The traveling wheel is equipped with a brake pad, which brakes the double-layer frame structure when it travels to a preset position.

[0049] In one specific embodiment, such as Figure 5 As shown, the first automatic expansion joint 121, the second automatic expansion joint 122, and the third automatic expansion joint 131 are connected to the automation control station 200. The automation control station 200 controls the operation of the first automatic expansion joint 121, the second automatic expansion joint 122, and the third automatic expansion joint 131 to achieve expansion and contraction adjustment. The coordinated expansion and contraction of the second automatic expansion joint 122 and the third automatic expansion joint 131 respectively drive the first slider 124 and the second slider 133 to slide, adjusting the included angle of the X-shaped extension arm adjusting rod. The positioning roller, driven by the cross extension arm adjusting rod, contacts the steel pipe pile, thereby controlling the position of the steel pipe pile. The automation control station 200 automatically calculates the verticality based on the positional deviation of the rollers of the first-layer positioning frame 100 and the second-layer positioning frame 101, and issues a verticality adjustment command to control the upper and lower positioning frames to make fine adjustments, thereby achieving verticality control.

[0050] The adjustable construction positioning frame for combined steel pipe piles provided by this invention, combined with an automated control station 200, can adjust the included angle of the X-shaped extension arm adjusting rods via an automatic telescopic device. Each steel pipe pile is positioned using three sets of X-shaped extension arm adjusting rods, enabling intelligent and precise positioning of combined steel pipe piles with different cross-sectional dimensions. It also assists in verticality adjustment, thereby improving the positioning accuracy and verticality of PC method combined steel pipe pile construction, reducing manual operation errors, and increasing construction efficiency. This invention is applicable to various PC method combined steel pipe piles of different diameters available on the market, offering a wide range of applications and a high degree of automation. The adjustable construction positioning frame adopts a double-layer frame structure, which not only makes the overall structure more stable and the positioning more accurate, but also allows for fine-tuning of the upper and lower positioning frames to control the verticality of the steel pipe piles.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
