Description

Technical Field

[0001] This invention relates to the technical field of bridge abutment construction, and specifically to a bridge abutment construction support device and method. Background Technology

[0002] To ensure the safety of bridge pier construction, foundation pit support work is required before construction. The core purpose is to prevent slope instability and collapse, prevent water and soil from flowing into the pit, achieve dry working conditions, and ensure the safety of the pit and surrounding structures. Currently, steel sheet pile support is commonly used in engineering projects. The specific construction method is as follows: steel sheet piles are driven one by one along the perimeter of the pier foundation pit, with the piles interlocking and connected sequentially to ultimately form a closed, continuous steel sheet pile retaining structure to meet the requirements for foundation pit support and water sealing.

[0003] Patent document CN113737790B discloses a method for simultaneous construction of bridge piles and sheet piles, including the following steps: dividing the bridge piles into several bridge piles to be constructed and several bridge piles already constructed, wherein the bridge piles to be constructed and the bridge piles to be constructed are distributed alternately; moving the drilling rig to one of the bridge piles to be constructed and constructing the bridge pile; and simultaneously, selecting one end at a predetermined distance from the bridge pile to be constructed as the starting point for driving the sheet piles, and driving the sheet piles within a predetermined range from the starting point; during the process of driving the sheet piles, if the sheet pile encounters a boulder and cannot sink, the driving is stopped, the sheet pile is left in its original position, and the driving of the next sheet pile continues until all the sheet piles within the predetermined distance from the starting point for driving the sheet piles are driven.

[0004] However, this scheme also has the following problems. During the construction of sheet pile driving, the uneven hardness of the geological conditions will directly lead to differences in the distribution of pile penetration resistance. In addition, the insufficient positioning accuracy of the driving guide device, uneven impact force transmission during hammering, and eccentric stress on the pile body are all factors that can easily cause the verticality of the sheet pile to exceed the standard and the pile body to be tilted. Such deviations will gradually accumulate and amplify, which will not only lead to inaccurate alignment of subsequent sheet pile splicing and difficulty in smooth closure of corners and closure sections, but also damage the interlocking tightness between the sheet piles, significantly reducing the water-stopping and seepage prevention effect of the foundation pit. At the same time, the tilting of the pile body and the non-straightness of the line will weaken the overall stress performance and overall stiffness of the retaining structure, causing problems such as uneven stress and excessive deformation, which will ultimately have an adverse impact on the construction quality and efficiency of the project. Summary of the Invention

[0005] This invention provides a bridge abutment construction support device and method, aiming to solve the problem in related technologies that steel sheet piles are prone to deflection during driving, thereby reducing construction quality and efficiency.

[0006] In a first aspect, the present invention provides a bridge abutment construction support device, comprising a guide bracket fixed to the ground, a receiving frame slidably mounted on the guide bracket along its length, a receiving rod rotatably mounted on the receiving frame, and a receiving sleeve rotatably and slidably mounted on the outside of the receiving rod; two sets of receiving rods and receiving sleeves are provided, and a connecting frame connecting the two sets of receiving sleeves is provided between them; a first auxiliary component and a second auxiliary component are respectively provided on the receiving sleeve and the receiving rod; the first auxiliary component is used for positioning when it cooperates with the inserted steel sheet pile, and the second auxiliary component guides the steel sheet pile to be inserted; after the insertion is completed, the receiving sleeve is rotated to separate the first auxiliary component from the inserted steel sheet pile, and then the receiving sleeve is slid to move the first auxiliary component to the next position to be inserted through the second auxiliary component, switching the first auxiliary component to the guiding function and the second auxiliary component to the positioning function.

[0007] Its effectiveness lies in enabling rapid switching and continuous operation between positioning of already inserted sheet piles and guiding sheet piles to be inserted, through the use of a receiving sleeve, a receiving rod, a first auxiliary component, and a second auxiliary component. Specifically, in the initial state, the first auxiliary component works with the already inserted sheet pile to position the device; simultaneously, the second auxiliary component guides the sheet pile to be inserted, ensuring its verticality and positional accuracy, thus improving construction precision. After the sheet pile is driven, the position of the first auxiliary component is adjusted to the corresponding position of the next sheet pile to be inserted, switching the first auxiliary component to a guiding function and the second auxiliary component to a positioning function. This, combined with the sliding of the receiving frame along the guide support, completes the work position switch, allowing the next sheet pile to be driven, thereby improving construction efficiency.

[0008] Preferably, the length of the receiving rod is three times that of the receiving sleeve, and it is divided into three equal sections along the axial direction: front, middle, and rear. The second auxiliary component is arranged in the middle of the receiving rod. When the first auxiliary component separates from the sheet pile and needs to be moved to the next sheet pile insertion position, the receiving sleeve moves from the front of the receiving rod through the middle to the rear. When the second auxiliary component separates from the sheet pile and needs to be moved to the next sheet pile insertion position, the receiving rod is displaced by moving the receiving frame, so that the receiving sleeve is once again located in the front of the receiving rod.

[0009] Its effect is to ensure that the single movement distance of the receiving sleeve and receiving rod is consistent and matches the size of the corresponding steel sheet pile, thereby improving construction efficiency.

[0010] Preferably, the first auxiliary component and the second auxiliary component have the same structure. The first auxiliary component includes: a connecting plate connected to the receiving sleeve and an auxiliary plate connected to the connecting plate. The auxiliary plate is located at the end of the connecting plate away from the receiving sleeve. Both the connecting plate and the auxiliary plate are provided in two sets, and each set corresponds to one of the two sets of receiving sleeves. The two sets of connecting plates are set to different lengths so that when the connecting plate is rotated to a horizontal position, the two auxiliary plates respectively cooperate with the inner and outer sides of the steel sheet pile. The connecting plate in the second auxiliary component is connected to the receiving rod.

[0011] Its effect is that by setting up an auxiliary plate, which works in conjunction with the sheet pile, the sheet pile can be prevented from shifting during driving, thus improving construction accuracy.

[0012] Preferably, the auxiliary plate and the connecting plate are rotatably connected, and a torsion spring is provided between the auxiliary plate and the connecting plate to connect the two. The torsion spring drives the upper end of the auxiliary plate to deflect away from the other auxiliary plate, so that the upper ends of the two auxiliary plates remain open.

[0013] Its effect is that the upper part of the auxiliary plate opens up so that the sheet pile can enter between the two auxiliary plates when it moves downwards for auxiliary positioning.

[0014] Preferably, two sets of first auxiliary components are provided at intervals along the length of the receiving sleeve. The two sets of first auxiliary components correspond one-to-one with two adjacent steel sheet piles. The same receiving sleeve is provided with a long connecting plate of one set of first auxiliary components and a short connecting plate of another set of first auxiliary components.

[0015] Its effect is that by setting up two sets of first auxiliary components in conjunction with two sheet piles, the overall stability is further improved.

[0016] Preferably, a through groove is provided on the receiving sleeve along its sliding direction, and the through groove and the connecting plate on the receiving sleeve are located in the same plane; when the receiving sleeve is moved, the receiving sleeve is rotated so that the through groove and the connecting plate on the receiving rod are axially aligned, so that the receiving sleeve can avoid and pass over the connecting plate on the receiving rod when it moves through the through groove.

[0017] Preferably, the front and rear parts of the receiving rod are respectively provided with locking blocks, and the inner wall of the receiving sleeve is provided with an annular locking groove along the circumferential direction. The inner wall of the receiving sleeve is also provided with a relief groove through the sliding direction, and the relief groove is connected to the locking groove. When the through groove is rotated to be axially aligned with the connecting plate on the receiving rod, the relief groove is simultaneously axially aligned with the locking block, so that the receiving sleeve can slide outside the locking block under the avoidance action of the relief groove. When the receiving sleeve moves to the front or rear position of the receiving rod, the locking block enters the corresponding connection between the locking groove and the relief groove. Then, rotating the receiving sleeve can make the locking block and the locking groove engage to fix the axial position of the receiving sleeve relative to the receiving rod.

[0018] Preferably, the outer circumferential surface of the receiving sleeve is provided with an annular groove, and the connecting frame includes: a connecting part and a mating part connected to the connecting part. Two mating parts are provided corresponding to the two sets of receiving sleeves. The mating part is provided with an arc-shaped groove that mates with the receiving sleeve. A retaining strip is provided on the inner wall of the arc-shaped groove, and the retaining strip rotatably engages with the annular groove.

[0019] Preferably, the receiving frame is provided with support plates on both sides, and the receiving sleeve and the receiving rod are located between the two support plates. When the connecting plate is rotated to the horizontal position, it abuts against the support plates.

[0020] Secondly, the present invention provides a bridge pier construction method, employing the aforementioned bridge pier construction support device, comprising the following steps: S1, Insert sheet piles at designated positions between guide supports; S2, assemble the auxiliary plate in the first auxiliary component with the sheet pile, at which point the auxiliary plate in the second auxiliary component is in the position to be driven in; S3, insert the sheet pile into the ground through the auxiliary plate in the second auxiliary component; S4, rotating the receiving sleeve separates the auxiliary plate inside the first auxiliary component from the sheet pile, and then sliding the receiving sleeve. At this time, the receiving rod is stationary, allowing the auxiliary plate inside the first auxiliary component to move to the next driving position. S5, insert the sheet pile into the ground through the auxiliary plate in the first auxiliary component; S6, rotate the receiving rod to separate the auxiliary plate inside the second auxiliary component from the sheet pile, then slide the receiving rod. At this time, the receiving sleeve is stationary, allowing the auxiliary plate inside the second auxiliary component to move to the next driving position. S7. Repeat steps S3 to S6 to insert multiple sheet piles into the ground in sequence.

[0021] Its effect is that by setting the first auxiliary component and the second auxiliary component to work together alternately, the construction position of the next sheet pile can be quickly confirmed. At the same time, the sheet pile can be provided with auxiliary support or guidance to avoid deviation and improve construction accuracy.

[0022] Beneficial effects: This invention achieves alternating positioning and guidance of the sheet pile by setting a rotatable and slidable receiving sleeve and receiving rod, in conjunction with a first auxiliary component and a second auxiliary component that can alternately cooperate with and position the sheet pile. This provides guidance and support during sheet pile insertion, avoids insertion deviation, and improves construction efficiency and accuracy. Attached Figure Description

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] This invention discloses a bridge abutment construction support device.

[0038] Reference Figures 1 to 12The bridge abutment construction support device includes a guide bracket 2, a receiving frame 3, a receiving rod 4, a receiving sleeve 5, a first auxiliary component 6, and a second auxiliary component 7. The guide bracket 2 is the basic bearing component, fixed at a designated position on the construction site. During installation, it is positioned to align with the pre-set driving position of the sheet piles 1, providing a reference guide for subsequent driving of the sheet piles 1. The receiving frame 3 is movably mounted on the guide bracket 2 and can slide smoothly along the length of the guide bracket 2. The receiving rods 4 are arranged along the length of the guide bracket 2, with two sets symmetrically distributed. Both sets of receiving rods 4 are fixed to the receiving frame 3 by rotational assembly and can move synchronously with the receiving frame 3. The receiving sleeve 5 is mounted on the outside of the receiving rod 4, using a dual-adaptive assembly form of rotation and sliding. It can rotate circumferentially around the receiving rod 4 and slide axially along the rod body. A connecting frame 8 is provided between the two sets of receiving sleeves 5, and the connecting frame 8 is connected to both receiving sleeves 5 to enable the two receiving sleeves 5 to move synchronously. The first auxiliary component 6 and the second auxiliary component 7 are respectively installed on the receiving sleeve 5 and the receiving rod 4. The two cooperate with each other and alternately play a positioning and guiding role to assist the steel sheet pile 1 in driving.

[0039] During the construction of the bridge abutment, the placement points of the guide support 2 are first determined by surveying and setting out. After the guide support 2 is firmly fixed to the ground, the first sheet pile 1 is driven into the ground using the reference guidance of the guide support 2. This serves as the reference pile for the subsequent driving of sheet piles 1, laying the foundation for the accuracy of the overall support construction. Subsequently, the first auxiliary component 6 is used in conjunction with the reference sheet pile 1 that has been driven into the ground. The first auxiliary component 6 is fixed and limited by the reference pile that has been positioned. Then, the position of the second auxiliary component 7 is precisely guided and positioned by the first auxiliary component 6, quickly delineating the working area for the sheet piles 1 to be driven. At the same time, the second auxiliary component 7 can guide the position of the sheet pile 1 when it is driven into the ground. This not only controls the driving point of the sheet pile 1, but also effectively constrains the driving posture of the sheet pile 1, greatly reducing the problems of deflection and misalignment during the driving process, and ensuring the verticality and positional accuracy of the driven sheet pile 1.

[0040] Reference Figure 1 , Figure 3 , Figure 10 After a single sheet pile 1 driving operation is completed, there is no need to disassemble the device or readjust the benchmark. Simply operate the receiving sleeve 5 to rotate around the receiving rod 4, so that the first auxiliary component 6 separates from the driven sheet pile 1 and releases the limiting constraint. Then, slide the receiving sleeve 5 along the axis of the receiving rod 4, so that the first auxiliary component 6 passes over the second auxiliary component 7 and moves to the working point of the next sheet pile 1 to be driven. Then switch the component operation mode and adjust the first auxiliary component 6 into a guiding component. At this time, the second auxiliary component 7 cooperates with the driven sheet pile 1 and becomes a positioning component. Based on the new positioning benchmark, the area to be driven is locked again, and the driving operation of the next sheet pile 1 is carried out.

[0041] During construction, the first auxiliary component 6 and the second auxiliary component 7 always maintain a state of mutual assistance and alternating operation. When one of them is in positioning mode and locking the benchmark position, the other component simultaneously plays a guiding role, planning a precise driving path for the sheet piles 1 to be inserted, ensuring that each sheet pile 1 can be accurately inserted into the preset point. There is no need for repeated measurement and layout or multiple adjustments to the device position throughout the process. This not only effectively improves the construction accuracy of the sheet pile 1 driving, but also reduces the phenomenon of deviation during the driving of the sheet pile 1, thus improving the construction quality.

[0042] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 The first auxiliary component 6 and the second auxiliary component 7 adopt the same structural form, both consisting of a connecting plate 61 and an auxiliary plate 62. In the first auxiliary component 6, the connecting plate 61 is connected to the receiving sleeve 5, and the connecting plate 61 is arranged perpendicular to the axis of the receiving sleeve 5; the auxiliary plate 62 is connected to the connecting plate 61 and is located at the end of the connecting plate 61 away from the receiving sleeve 5.

[0043] Both the connecting plate 61 and the auxiliary plate 62 are configured in two sets, and are arranged in a one-to-one correspondence with the two sets of receiving sleeves 5. The two sets of connecting plates 61 are designed with different lengths. When the connecting plate 61 is rotated to the horizontal position, the two sets of auxiliary plates 62 can cooperate with the inner and outer side walls of the sheet pile 1 respectively to achieve the clamping, positioning or guiding function of the sheet pile 1.

[0044] The connecting plate 61 in the second auxiliary component 7 is connected to the receiving rod 4.

[0045] When the connecting plate 61 rotates to the horizontal position, with the help of the two sets of auxiliary plates 62 and the inner and outer sides of the sheet pile 1, a stable positioning support or movement guide can be formed for the sheet pile 1, ensuring the positional accuracy of the sheet pile 1 during construction.

[0046] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 Two sets of first auxiliary components 6 are arranged at intervals along the length of the receiving sleeve 5, and two sets of second auxiliary components 7 are also arranged at intervals along the length of the receiving rod 4. The two sets of first auxiliary components 6 correspond one-to-one with two adjacent sheet piles 1, and the two sets of first auxiliary components 6 correspond one-to-one with two adjacent sheet piles 1 respectively. The long connecting plate 61 in the first auxiliary component 6 and the short connecting plate 61 in the other set of first auxiliary components 6 are located on the same receiving sleeve 5.

[0047] Therefore, the first auxiliary component 6 on the receiving sleeve 5 can simultaneously cooperate with two sheet piles 1; after each adjustment of the position of the first auxiliary component 6 or the second auxiliary component 7, two sheet piles 1 can be driven in simultaneously, and the movement distance of the receiving sleeve 5 relative to the receiving rod 4 is adapted to the size of the two sheet piles 1. In other embodiments, the number of the first auxiliary components 6 can be adjusted according to the construction conditions to meet the requirement of driving different numbers of sheet piles 1 in a single operation. At the same time, by setting the first auxiliary component 6 to cooperate with two sheet piles 1 simultaneously, the stability of the overall structure when the first auxiliary component 6 is positioned can be further improved.

[0048] Reference Figure 6 To facilitate the smooth rotation of the connecting plate 61 to the horizontal working position, a support plate 9 is fixedly installed on the receiving frame 3. Two support plates 9 are symmetrically arranged along the width direction of the receiving frame 3, located on the left and right sides of the receiving frame 3 respectively. The receiving sleeve 5 and the receiving rod 4 are both located in the area between the two support plates 9.

[0049] When the connecting plate 61 rotates to a horizontal position towards the sheet pile 1, the lower end face of the connecting plate 61 abuts against the upper end face of the support plate 9. The support plate 9 provides stable support and limits the connecting plate 61, keeping it in a horizontal position. At this time, the connecting plate 61 can position the sheet pile 1 or provide guidance for driving the sheet pile 1. Since the sheet pile 1 is inserted into the ground from top to bottom during driving, the connecting plate 61 can remain in contact with the support plate 9 during the process, improving stable guidance and preventing deviation during downward driving. When the connecting plate 61 rotates away from the sheet pile 1 and abuts against the support plate 9, the auxiliary plate 62 rotates synchronously with the connecting plate 61 and separates from the sheet pile 1, facilitating subsequent adjustment of the position of the receiving sleeve 5 or the receiving rod 4.

[0050] Reference Figure 6 The lower end of the auxiliary plate 62 is rotatably connected to the connecting plate 61. Torsion springs are installed between the two and connected to each other. The elastic force of the torsion springs drives the upper end of the auxiliary plate 62 to deflect away from the other auxiliary plate 62, so that the upper ends of the two auxiliary plates 62 remain open outward in their natural state.

[0051] When the auxiliary plate 62 guides the sheet pile 1 during driving, in the initial state before the sheet pile 1 contacts the auxiliary plate 62, the elastic force of the torsion spring causes the upper ends of the two auxiliary plates 62 to open outward, forming a guide opening that is wider at the top and narrower at the bottom, facilitating the smooth insertion of the sheet pile 1 between the two auxiliary plates 62. After the sheet pile 1 is driven downward and enters the space between the two auxiliary plates 62, the side wall of the sheet pile 1 will squeeze the auxiliary plate 62, overcoming the torsion spring force, causing the auxiliary plate 62 to rotate inward to a vertical position, thereby forming a double-sided clamp and limit on the sheet pile 1, effectively preventing the sheet pile 1 from tilting, shaking, or misaligning during driving, and ensuring driving accuracy and verticality.

[0052] Reference Figure 3 The sheet pile 1 consists of a web 11 and symmetrically arranged flanges 12 on both sides of the web 11. The flanges 12 are inclined relative to the web 11, forming a lateral mating structure with a specific inclination angle. The two sides of the auxiliary plate 62 are designed with the same inclination angle as the flanges 12 of the sheet pile 1, so that its side profile can fit with the inclined surface of the flanges 12 of the sheet pile 1. During the assembly process, a stable surface contact constraint is formed, which effectively enhances the stability between the auxiliary plate 62 and the sheet pile 1. At the same time, the mating of the side of the auxiliary plate 62 with the flanges 12 can provide a reliable lateral limiting effect when the auxiliary plate 62 is mated with the sheet pile 1 that has been driven into place, restricting the lateral slippage of the auxiliary plate 62 relative to the sheet pile 1, ensuring that the two maintain a precise relative position during assembly and construction, and guaranteeing the positioning accuracy and assembly reliability of the overall structure.

[0053] Reference Figure 1 , Figure 3 , Figure 5 The length of the receiving rod 4 is three times the length of the receiving sleeve 5, and it is divided into three equal sections along the axial direction from front to back: front, middle and rear. The second auxiliary component 7 is arranged in the middle area of ​​the receiving rod 4.

[0054] When the first auxiliary component 6 needs to be moved to the next sheet pile 1 insertion position, the receiving sleeve 5 is rotated 180 degrees to separate the auxiliary plate 62 inside the first auxiliary component 6 from the sheet pile 1. At the same time, the connecting plate 61 inside the first auxiliary component 6 is rotated to abut against another support plate 9 to avoid interference between the second auxiliary component 7 and the connecting plate 61 inside the first auxiliary component 6 during the movement of the receiving sleeve 5. Subsequently, the receiving sleeve 5 slides axially along the receiving rod 4, moving from the front, through the middle, to the rear of the receiving rod 4. Finally, the receiving sleeve 5 is rotated to reset the connecting plate 61, completing one work position switch.

[0055] When the second auxiliary component 7 needs to be moved to the next sheet pile 1 to be inserted, rotate the receiving rod 4 to separate the auxiliary plate 62 inside the second auxiliary component 7 from the sheet pile 1; then move the receiving frame 3 to drive the receiving rod 4 to move as a whole. At this time, since the auxiliary plate 62 inside the first auxiliary component 6 is still in contact with the sheet pile 1, the receiving sleeve 5 remains stationary. The receiving sleeve 5 can be moved back to the front of the receiving rod 4 by moving the receiving rod 4, thus completing the switching of the positions of the first auxiliary component 6 and the second auxiliary component 7 again.

[0056] By limiting the length ratio of the receiving rod 4 to the receiving sleeve 5, it can be ensured that the movement stroke of the receiving sleeve 5 is equal to that of the receiving rod 4 each time, and that this movement stroke matches the external dimensions of the sheet pile 1. This enables rapid and precise positioning during construction, effectively reducing alignment adjustment time and significantly improving the operational efficiency of the sheet pile 1 driving operation.

[0057] Reference Figure 4The receiving frame 3 is provided with rollers 31 that cooperate with the guide bracket 2. By providing rollers 31, the friction between the receiving frame 3 and the guide bracket 2 is reduced, so as to adjust the position of the receiving frame 3.

[0058] Reference Figure 3 , Figure 5 , Figure 7 , Figure 9 A through groove 51 is provided on the receiving sleeve 5 along its axial sliding direction. The through groove 51 and the connecting plate 61 fixed on the receiving sleeve 5 are located in the same radial plane, and the through groove 51 and the connecting plate 61 are centrally symmetrical about the axis of the receiving sleeve 5.

[0059] Before the receiving sleeve 5 needs to be moved axially, it is first rotated around its own axis so that the through groove 51 on the receiving sleeve 5 is aligned with the connecting plate 61 on the receiving rod 4 in the axial direction and their positions correspond. At this time, the connecting plate 61 on the receiving sleeve 5 rotates to abut against another support plate 9. By opening the through groove 51 on the receiving sleeve 5, a clearance space can be provided for the connecting plate 61 on the receiving rod 4 during the axial movement of the receiving sleeve 5, so that the receiving sleeve 5 can smoothly pass over the connecting plate 61 on the receiving rod 4, effectively avoiding interference from the connecting plate 61 on the receiving rod 4 to the axial movement of the receiving sleeve 5.

[0060] Similarly, when it is necessary to move the receiving rod 4 axially, first rotate the receiving rod 4 180 degrees around its axis so that the connecting plate 61 on the receiving rod 4 corresponds axially with the through groove 51 on the receiving sleeve 5. At this time, during the process of the receiving rod 4 sliding axially, the connecting plate 61 on the receiving rod 4 can smoothly pass through the through groove 51 of the receiving sleeve 5 and pass over the receiving sleeve 5, avoiding interference from the receiving sleeve 5 on the axial movement of the receiving rod 4, thereby ensuring that the receiving sleeve 5 and the receiving rod 4 can achieve relative axial sliding without interference.

[0061] Reference Figure 8 , Figure 9 , Figure 11 , Figure 12 To prevent relative slippage between the receiving sleeve 5 and the receiving rod 4 after the positions are adjusted, a locking block 41 is provided at the front and rear positions of the receiving rod 4, respectively. The inner wall of the receiving sleeve 5 is provided with an annular locking groove 52 along the circumferential direction, and the inner wall of the receiving sleeve 5 is provided with a relief groove 53 along its axial sliding direction. The relief groove 53 and the annular locking groove 52 are interconnected.

[0062] When it is necessary to adjust the relative position of the receiving sleeve 5 and the receiving rod 4, rotating the receiving sleeve 5 axially aligns the through groove 51 with the connecting plate 61 on the receiving rod 4, while simultaneously axially aligning the clearance groove 53 with the locking block 41 on the receiving rod 4. At this time, the locking block 41 can freely pass through the clearance groove 53, and the receiving sleeve 5 can smoothly slide axially relative to the receiving rod 4 under the clearance action of the clearance groove 53, thereby realizing the adjustment of their relative position. When the receiving sleeve 5 moves axially to the preset working position at the front or rear of the receiving rod 4, the locking block 41 enters the corresponding communication position between the clearance groove 53 and the annular locking groove 52. At this time, rotating the receiving sleeve 5 causes the locking block 41 to rotate from the clearance groove 53 into the annular locking groove 52, forming a circumferential engagement with the annular locking groove 52.

[0063] The axial limiting effect of the annular groove 52 on the block 41 restricts the axial movement of the receiving sleeve 5 relative to the receiving rod 4, thereby reliably fixing the receiving sleeve 5 in the preset position, avoiding mutual slippage between the receiving sleeve 5 and the receiving rod 4 during use, and ensuring the driving accuracy of the sheet pile 1.

[0064] Reference Figure 3 , Figure 5 , Figure 7 By setting a connecting frame 8 between the two receiving sleeves 5, the synchronous sliding of the two receiving sleeves 5 can be achieved. To avoid interference of the connecting frame 8 with the rotational movement of the receiving sleeves 5, and to ensure that the receiving sleeves 5 can rotate freely relative to the connecting frame 8 and move synchronously with the connecting frame 8, an annular groove 54 is provided circumferentially on the outer wall of each receiving sleeve 5. The connecting frame 8 includes a connecting part 81 and a mating part 82 fixedly connected to the connecting part 81. Two mating parts 82 are set for each of the two sets of receiving sleeves 5. Each mating part 82 is provided with an arc-shaped groove 821 that matches the shape of the receiving sleeve 5. The inner wall of the arc-shaped groove 821 abuts against the outer side of the receiving sleeve 5. An inwardly protruding retaining strip 822 is provided on the inner wall of the arc-shaped groove 821. The retaining strip 822 matches the annular groove 54 on the receiving sleeve 5 and forms a rotational fit.

[0065] In the assembled state, the retaining strip 822 is embedded in the annular groove 54, and the receiving sleeve 5 can rotate freely around its own axis relative to the retaining strip 822 and the mating part 82. Simultaneously, the retaining strip 822 forms a limiting fit with the annular groove 54 in both the axial and radial directions. When one of the receiving sleeves 5 moves axially, the receiving sleeve 5 pushes the retaining strip 822 through the groove wall of the annular groove 54, thereby causing the corresponding mating part 82 to generate axial displacement. The movement of the mating part 82 is transmitted to the other mating part 82 through the connecting part 81, causing the other mating part 82 to move synchronously, and through the fit between the retaining strip 822 and the annular groove 54, it drives the other receiving sleeve 5 to move axially synchronously. This allows the receiving sleeve 5 to rotate normally while also achieving synchronous sliding of the two receiving sleeves 5 in the axial direction, effectively improving the positioning accuracy during the driving of the sheet pile 1 and ensuring construction quality.

[0066] The implementation principle of this invention is as follows: In the initial state, the guide bracket 2 is first fixed in place, and the sheet pile 1 is inserted into the preset position on the ground. The auxiliary plate 62 in the first auxiliary component 6 is engaged with the already positioned sheet pile 1. At this time, the auxiliary plate 62 in the second auxiliary component 7 is located at the position to be driven next sheet pile 1. After the sheet pile 1 at the second auxiliary component 7 is completed, the receiving sleeve 5 is rotated to disengage the auxiliary plate 62 in the first auxiliary component 6 from the sheet pile 1; then the receiving sleeve 5 is slid along the guide direction to move the first auxiliary component 6 to the next construction area, and the above steps are repeated to complete the continuous driving construction of the sheet pile 1.

[0067] By alternately adjusting the positions of the receiving sleeve 5 and the receiving rod 4, with each movement of the receiving sleeve 5 or the receiving rod 4 being the same distance and matching the dimensions of the sheet pile 1, the first auxiliary component 6 and the second auxiliary component 7 are alternately switched to the positioning position and the guiding position. Since the auxiliary plate 62, when in conjunction with the sheet pile 1, allows one of the receiving sleeve 5 and the receiving rod 4 to move while the other remains stationary, the insertion position of the next sheet pile 1 can be quickly determined, significantly improving construction efficiency. Simultaneously, during the downward driving of the sheet pile 1, the auxiliary plate 62 guides and supports the sheet pile 1, effectively preventing deviations and misalignments during driving, thus improving the overall accuracy and stability of the sheet pile 1 construction.

[0068] The present invention also discloses a method for constructing bridge abutments, using the aforementioned bridge abutment construction support device.

[0069] A method for constructing bridge pier caps includes the following steps: S1, insert sheet piles 1 at designated positions between guide supports 2; S2, the auxiliary plate 62 in the first auxiliary component 6 is matched with the sheet pile 1, at which time the auxiliary plate 62 in the second auxiliary component 7 is in the position to be driven in. S3, insert the sheet pile 1 into the ground through the auxiliary plate 62 in the second auxiliary component 7; S4, rotate the receiving sleeve 5 to separate the auxiliary plate 62 inside the first auxiliary component 6 from the sheet pile 1, then slide the receiving sleeve 5. At this time, the receiving rod 4 is stationary, so that the auxiliary plate 62 inside the first auxiliary component 6 moves to the next place to be driven. S5, insert the sheet pile 1 into the ground through the auxiliary plate 62 in the first auxiliary component 6; S6, rotate the receiving rod 4 to separate the auxiliary plate 62 in the second auxiliary component 7 from the sheet pile 1, then slide the receiving rod 4. At this time, the receiving sleeve 5 is stationary, so that the auxiliary plate 62 in the second auxiliary component 7 moves to the next place to be driven. S7. Repeat steps S3 to S6 to insert multiple sheet piles 1 into the ground in sequence.
