Description

Technical Field

[0001] This utility model relates to the field of pile driving construction technology, and in particular to a pile driving guide device and an HLC method pile driving system. Background Technology

[0002] HLC (High-Lower-Low) piles are a new type of support system combining sheet piles and H-beams. It combines two different types of piles—H-beams and Larssen sheet piles—and utilizes the high rigidity of the H-beams to control deformation, resulting in high strength, high bearing capacity, and fast construction speed.

[0003] However, due to this support method, the H-beams need to be inserted into the grooves of the sheet piles, with no connection between the sheet piles and the H-beams. During construction, the H-beams may deviate from the sheet piles, resulting in gaps between them. Excessive gaps prevent the H-beams from fully utilizing their load-bearing stiffness, and significant deviations can also affect the construction of the main structure, causing unnecessary problems. Currently, most mainstream construction methods use welded reinforcing bars as a reference to control the positioning of the H-beams, but this method still cannot accurately position them and cannot effectively control deformation.

[0004] Therefore, it is necessary to provide a piling guidance device and an HLC method piling system to solve the above-mentioned problems in the prior art. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a piling guidance device and an HLC method piling system to solve the technical problem that the prior art cannot accurately position the piles during HLC method piling.

[0006] To solve the above-mentioned technical problems, this utility model provides a piling guidance device for driving HLC method piles, wherein the HLC method pile includes steel sheet piles and H-beams, comprising:

[0007] A lateral limiting mechanism is used to laterally limit the steel sheet pile and the H-beam;

[0008] The first vertical limiting mechanism includes a guide part, and a guide groove corresponding to the locking opening of the steel sheet pile is provided on one side of the guide part for vertically limiting the steel sheet pile;

[0009] The second vertical limiting mechanism includes a limiting part, on which an H-shaped hole corresponding to the H-beam is provided for vertically limiting the H-beam.

[0010] The piling guidance device provided by this utility model has the following beneficial effects:

[0011] Laterally, the sheet piles and H-beams are laterally positioned using a lateral limiting mechanism to ensure accurate lateral positioning during pile driving. After defining the lateral position, a guide groove corresponding to the locking jaws of the sheet piles is provided on the guide section of the first vertical limiting mechanism. During the hoisting and installation of the sheet piles, the locking jaws align with the guide grooves, and the piles are driven into the ground, ensuring that the vertical position of the sheet piles does not shift. After the sheet pile installation is completed, an H-shaped hole corresponding to the cross-section of the H-beams is provided on the limiting section of the second vertical limiting mechanism. When the H-beam is hoisted for construction, its cross-section is aligned with the H-shaped hole and driven into the ground. This ensures that the vertical position of the H-beam is confined within the H-shaped hole and does not shift. It also ensures that the H-beam is driven into the groove of the sheet pile and that the distance between the H-beam and the sheet pile does not deviate too much, thus ensuring that the H-beam can play its role in bearing rigidity. The piling guide device of this utility model has a simple structure, is easy to operate, and is highly feasible. It limits the lateral and vertical positions of the sheet pile and H-beam during piling construction, greatly shortening the piling construction time and improving piling efficiency.

[0012] Furthermore, the guide portion includes a first frame and a cover plate covering the first frame, and the guide groove is formed on one side of the first frame and the cover plate.

[0013] Furthermore, the first vertical limiting mechanism also includes a support plate, which is disposed at the bottom of the guide portion.

[0014] Furthermore, the lateral limiting mechanism includes a first guide beam and a second guide beam, which are arranged opposite each other at a certain distance.

[0015] Furthermore, the limiting part includes a second frame and a limiting plate covering the second frame, and the H-shaped hole is formed on the limiting plate.

[0016] Furthermore, the second vertical limiting mechanism also includes a slot plate, which is disposed at the bottom of the limiting part.

[0017] Furthermore, the thickness of the card slot plate is 20 centimeters.

[0018] Furthermore, the slot plate is made of channel steel.

[0019] Furthermore, the first frame or the second frame is formed by multiple channel steels arranged sequentially.

[0020] To solve the above-mentioned technical problems, this utility model provides an HLC method pile driving system, comprising:

[0021] The beneficial effects of the HLC method pile driving system provided by this utility model are the same as those of the pile driving guide device described above. Attached Figure Description

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0030] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model. The following detailed description should not be considered restrictive, and the scope of the embodiments of this application is limited only by the claims of the published patents.

Spatial terms such as "upper," "lower," "left," "right," "below," "below," "lower part," "above," "upper part," etc., may be used in the text to illustrate the relationship between one element or feature shown in the figures and another element or feature.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "holding" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, operation, element, component, item, kind, and / or group, but do not preclude the presence, occurrence, or addition of one or more other features, operations, elements, components, items, kinds, and / or groups. The terms “or” and “and / or” as used herein are interpreted as inclusive, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition arise only when combinations of elements, functions, or operations are inherently mutually exclusive in some manner.

[0033] like Figure 1-5 As shown, an embodiment of this utility model provides a piling guidance device for driving HLC method piles. It should be understood that the HLC method pile is a novel support method combining sheet piles and H-beams. During piling construction, the support structure needs to withstand significant soil and water pressure. Inserting the H-beams into the grooves of the sheet piles effectively reduces lateral deformation of the support structure due to the high strength and large moment of inertia of the H-beams, thus better protecting the stability of the foundation pit. The piling guidance device includes: a lateral limiting mechanism 1, a first vertical limiting mechanism 2, and a second vertical limiting mechanism 3. Through the cooperation of the lateral limiting mechanism 1, the first vertical limiting mechanism 2, and the second vertical limiting mechanism 3, excessive gaps are prevented when the H-beams are inserted into the grooves of the sheet piles, thus leveraging the load-bearing stiffness of the H-beams and effectively controlling the deformation of the support structure.

[0034] The lateral limiting mechanism 1 is used to laterally limit the sheet pile 4 and the H-beam 5. The first vertical limiting mechanism 2 includes a guide part 21. A guide groove 211 corresponding to the locking opening of the sheet pile 4 is provided on one side of the guide part 21 for vertically limiting the sheet pile 4. The second vertical limiting mechanism 3 includes a limiting part 31. An H-shaped hole 311 corresponding to the H-beam 5 is provided on the limiting part 31 for vertically limiting the H-beam 5.

[0035] Laterally, the sheet pile 4 and H-beam 5 are laterally limited by the lateral limiting mechanism 1 to ensure accurate lateral positioning of the sheet pile 4 and H-beam 5 during pile driving. After the lateral position is limited, the sheet pile 4 is driven into the guide pile 4 by the guide groove 211 on the guide part 21 of the first vertical limiting mechanism 2, which corresponds to the locking slot of the sheet pile 4. This ensures that the vertical position of the sheet pile 4 will not shift. After the sheet pile 4 is completed, the sheet pile 4 is driven into the guide groove 211 on the limiting part 31 of the second vertical limiting mechanism 3, which corresponds to the cross section of the H-beam 5. The H-shaped hole 311 is used to guide the H-beam 5 during construction. When the H-beam 5 is hoisted, its cross-section is aligned with the H-shaped hole 311 and driven into the ground. This ensures that the vertical position of the H-beam 5 is confined within the H-shaped hole 311 when it is driven into the ground. It also ensures that the H-beam 5 will not deviate relative to the sheet pile 4 when it is driven into the ground, and that the gap of the H-beam 5 in the groove of the sheet pile 4 is controllable. The piling guide device of this utility model has a simple structure, is easy to operate, and is highly feasible. It limits the lateral and vertical positions of the sheet pile 4 and the H-beam 5 during piling construction, which greatly shortens the construction time and improves the piling efficiency.

[0036] It should be noted that in this utility model, the horizontal direction refers to the direction parallel to the ground, and the vertical direction refers to the direction perpendicular to the ground.

[0037] like Figure 3 As shown, in some embodiments of the present invention, the guide portion 21 includes a first frame 212 and a cover plate 213 covering the first frame 212. A guide groove 211 is formed on one side of the first frame 212 and the cover plate 213.

[0038] In some specific embodiments, the first frame 212 is formed by sequentially assembling multiple channel steels. For example, a rectangular frame structure is formed by welding four channel steels together. A cover plate 213 is laid on the rectangular frame structure to form a platform. Specifically, the cover plate 213 is a 10mm checkered steel plate. The checkered steel plate has an anti-slip function, improving the safety of workers during construction. A guide groove 211 is formed on one side of the rectangular frame structure and the checkered steel plate, thus adapting to the locking joint of the sheet pile 4, facilitating the vertical sinking of the sheet pile 4 into the ground along the groove opening of the guide groove 211. It should be noted that the size of the groove opening of the guide groove 211 should be specifically designed according to the locking joint of the sheet pile 4 to ensure that the locking joint can be sunk into the ground along the guide groove 211. For example, the guide groove 211 has a width of 6cm and a depth of 5cm.

[0039] like Figure 5As shown, in some embodiments of this utility model, the first vertical limiting mechanism 2 further includes a support plate 22. The support plate 22 is disposed at the bottom of the guide portion 21. To avoid the guide portion 21 becoming a consumable part and increasing production costs, a support plate 22 is provided at the bottom of the guide portion 21. The support plate 22 is directly snapped and fixed to the transverse limiting mechanism 1, and spot welding is used for reinforcement if necessary. After the sheet pile 4 is driven, only the support plate 22 needs to be disassembled, and the guide portion 21 can be reused, reducing production costs.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the lateral limiting mechanism 1 includes a first guide beam 11 and a second guide beam 12. The first guide beam 11 and the second guide beam 12 are arranged opposite each other at a certain distance. Specifically, both the first guide beam 11 and the second guide beam 12 are made of structural steel.

[0041] It should be understood that the sheet pile 4 includes inner sheet piles 41 and outer sheet piles 42. During construction, the sheet piles with grooves facing the foundation pit are inner sheet piles 41, and the sheet piles with grooves facing the periphery of the foundation pit are outer sheet piles 42. Only H-beams 5 need to be inserted into the grooves of the inner sheet piles 41 to effectively control the deformation of the support structure. Specifically, when laterally limiting the sheet piles 4, the first guide beam 11 and the second guide beam 12 are arranged according to the width of the inner sheet piles 41 and the outer sheet piles 42 when they are fastened together, serving as the distance between the first guide beam 11 and the second guide beam 12. This confines the sheet piles 4 between the first guide beam 11 and the second guide beam 12, thereby achieving the lateral positioning of the sheet piles 4. When laterally limiting the H-beams 5, the first guide beam 11 and the second guide beam 12 are arranged according to the width of the grooves of the inner sheet piles 41 and the H-beams 5 when they are installed together, serving as the distance between the first guide beam 11 and the second guide beam 12, thereby achieving the lateral positioning of the H-beams 5. By using the pre-fixed distance between the first guide beam 11 and the second guide beam 12, the sheet pile 4 and the H-beam 5 are locked in the lateral position, thereby achieving lateral positioning.

[0042] like Figure 4 As shown, in some embodiments of the present invention, the limiting part 31 includes a second frame 312 and a limiting plate 313 covering the second frame 312. An H-shaped hole 311 is formed on the limiting plate 313.

[0043] Since HLC pile construction relies primarily on the high strength and rigidity of H-beams 5 to effectively control the deformation of the support structure, the vertical position of the H-beams 5 during pile driving needs to be accurately controlled. This ensures that the H-beams 5 are inserted into the ground within the groove of the sheet piles 4, without creating large gaps, and fit as closely as possible to the sheet piles 4. This allows the H-beams 5 to exert their load-bearing rigidity and effectively control the deformation of the support structure. Therefore, by opening an H-shaped hole 311 on the limiting plate 313, and placing the second vertical limiting mechanism 3 on the first guide beam 11 and the second guide beam 12 beforehand, the H-shaped hole 311 is positioned at the predetermined location of the H-beams 5. The H-beams 5 are then hoisted, aligned with the H-shaped hole 311, and driven into the ground. At this point, the H-beams 5 are driven into the groove of the sheet piles 4 at the predetermined location, effectively controlling the deformation of the support structure.

[0044] In some specific embodiments, the second frame 312 is formed by sequentially assembling multiple channel steels. For example, a rectangular frame structure is formed by sequentially welding four channel steels as edges. A limiting plate 313 is laid on the rectangular frame structure. Specifically, the limiting plate 313 is made of patterned steel plate. Exemplarily, channel steel is pre-welded into an "H" shape that adapts to the cross-section of the H-beam 5. Using this "H" shape as a reference, H-shaped holes 311 corresponding to the "H" shape are opened on the patterned steel plate, so that the cross-section of the H-beam 5 is aligned with the H-shaped holes 311 and then sunk into the ground.

[0045] like Figure 2 As shown, in some embodiments of this utility model, the second vertical limiting mechanism 3 further includes a slot plate 32. The slot plate 32 is disposed at the bottom of the limiting part 31. Specifically, the slot plate 32 is a channel steel with a thickness of 20 cm. Four 20 cm channel steels are welded to the bottom of the limiting part 31 as slot plates 32, which can be directly snapped onto the first guide beam 11 and the second guide beam 12, and spot welding can be used for reinforcement if necessary. For example, the distance between the two channel steels located on the first guide beam 11 and the second guide beam 12 is preferably 1 cm to 2 cm greater than the width between the first guide beam 11 and the second guide beam 12. After the piling construction is completed, the slot plate 32 can be disassembled, and the limiting part 31 can be reused, reducing construction costs.

[0046] like Figures 1-5 As shown, an embodiment of this utility model also provides an HLC method pile driving system, including: a pile driving guide device and a driving device as described above. The driving device is used to drive the sheet pile 4 and H-beam 5 into the pile via the pile driving guide device.

[0047] For example, the piling construction steps of the HLC method piling system of this utility model are as follows:

[0048] The width of the interlocking joints of the inner sheet piles 41 and outer sheet piles 42 to be constructed is measured and used as the basis for installing the first guide beam 11 and the second guide beam 12. After the first guide beam 11 and the second guide beam 12 are installed, the first vertical limiting mechanism 2 is placed on the first guide beam 11 and the second guide beam 12, specifically secured by the support plate 22. If necessary, spot welding is used for reinforcement, and the opening of the guide groove 211 is aligned with the interlocking joint of the inner sheet pile 41. After the first vertical limiting mechanism 2 is installed, the interlocking joints of the inner sheet piles 41 and outer sheet piles 42 are aligned and interlocked. A driving device, such as a crane or pile driver, is used to lift the sheet piles 4. After aligning the interlocking joint of the inner sheet pile 41 with the guide groove 211, it is vertically driven into the ground along the guide groove 211. After the sheet pile 4 construction is completed, the first guide beam 11 and the second guide beam 12 are removed. 2. Based on the measured width of the groove of the inner sheet pile 41 and the H-beam 5 when installed together, reinstall the first guide beam 11 and the second guide beam 12 to position the H-beam 5 in the lateral direction. After reinstalling the first guide beam 11 and the second guide beam 12, place the second vertical limiting mechanism 3 on the reinstalled first guide beam 11 and the second guide beam 12, specifically by engaging the slot plate 32 with the first guide beam 11 and the second guide beam 12. Place the H-shaped hole 311 at the preset position of the H-beam 5 to be piled. Use a driving device, such as a crane or a pile driver, to clamp the H-beam 5 to the H-shaped hole 311, so that the "H" shape of the H-beam 5 cross section is aligned with the H-shaped hole 311. Drive the H-beam 5 into the ground along the H-shaped hole 311, so that the H-beam 5 is inserted into the groove of the inner sheet pile 41, ensuring that the gap between the H-beam 5 and the sheet pile 4 is controllable. Continue to the next location and repeat the operation for pile driving.

[0049] In summary, addressing the technical problem that existing HLC (High-Lower Cemented Ladder) pile driving technology cannot accurately position sheet piles and H-beams, this invention provides a pile driving guide device and an HLC pile driving system to assist in guiding HLC pile driving. A lateral limiting mechanism laterally limits the sheet pile and H-beam, ensuring accurate lateral positioning during pile driving. After limiting the lateral position, a guide groove corresponding to the locking jaw of the sheet pile is provided on the guide part of the first vertical limiting mechanism. When the sheet pile is hoisted, the locking jaw aligns with the guide groove for driving, ensuring the vertical position of the sheet pile remains within the guide groove. The following steps address the issue of offset during sheet pile installation: After the sheet pile construction is completed, an H-shaped hole corresponding to the cross-section of the H-beam is opened on the limiting part of the second vertical limiting mechanism. When the H-beam is hoisted for construction, its cross-section aligns with the H-shaped hole for insertion, ensuring that the vertical position of the H-beam is confined within the H-shaped hole when it sinks into the ground. This prevents the H-beam from shifting relative to the sheet pile during insertion and ensures controllable gaps within the sheet pile groove. This new piling guide device is simple in structure, easy to operate, and highly feasible. It limits the lateral and vertical positions of the sheet piles and H-beams during piling, significantly shortening construction time and improving piling efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
