Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wharf construction equipment, in particular to a wharf berthing component counter-pressure installation device and a method for installing the same. BACKGROUND

[0002] The installation of a berthing component is one of the core processes of wharf construction, and the construction quality directly determines the pouring progress of the upper structure of the wharf. The conventional installation methods are the resting method and the suspension method, and the core logic of the two processes depends on large-scale hoisting equipment to suspend the berthing component and complete positioning and installation. However, the offshore construction environment is complex, and the component is easily disturbed by wind and waves during hoisting, resulting in poor stability of the component in place and difficulty in accurately controlling the installation precision.

[0003] In view of the installation problem of the berthing component, a temporary positioning device for a berthing component in a shallow water area and a construction method are disclosed in patent application CN119913860A, which sets a connecting rod and a supporting rod between wharf foundation piles, forms a support in cooperation with the positioning hole and the fixed rod of the berthing component, and then realizes temporary fixing by means of a positioning block and a fixing clamp and other mechanisms. Although the stability problem of the suspension type installation is improved, the positioning mechanism can only limit the position of the fixed rod through the sliding groove, and lacks the active adjustment ability of the horizontal degree of the berthing component. Patent CN212641367U discloses a berthing component that reduces construction difficulty, which sets a bearing hole in the corbel A, uses a supporting rod to be erected on the bearing beam to realize support and positioning, and guides the berthing component to fit the supporting pile through the inclined sliding seat. However, the adjustment method relies on the sliding of the self-weight of the berthing component, and cannot accurately control the horizontal precision.

[0004] In summary, although the existing technology has improved in temporary support and preliminary positioning, it has not solved the problem of accurate adjustment of the horizontal degree of the berthing component during installation. Especially in complex offshore environments, the berthing component is easily deviated during installation due to unbalanced support and lagging adjustment, which affects the subsequent pouring quality of the wharf. Therefore, it is a key requirement to design a wharf berthing component installation device and method that can realize horizontal degree adjustment and improve installation precision to solve the current technical bottleneck.

[0036] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described herein and with modifications thereof, without departing from the scope of the present application, and it is intended that the present application not be limited to the following disclosure.

[0037] Referring to Figure 1 and Figure 2 , the reverse pressure installation device for the wharf berthing component in an embodiment of the present application can at least improve the installation accuracy of the wharf berthing component. Specifically, the reverse pressure installation device comprises a distribution beam 3, a support mechanism 2, a lifting mechanism 4, a settlement adjustment mechanism 5 and a butt steel frame 6. The support mechanism 2 comprises a fixed clamp 21 mounted on the outer wall of the cast-in-place pile 1 by bolts, an adjustment steel frame 22 and a height fine adjustment assembly 23. The height fine adjustment assembly 23 is mounted on the fixed clamp 21, and the adjustment steel frame 22 is connected to the height fine adjustment assembly 23. The height fine adjustment assembly 23 is used to adjust the up-and-down movement of the adjustment steel frame 22 relative to the fixed clamp 21. One end of the distribution beam 3 is arranged on the adjustment steel frame 22. The lifting mechanism 4 is arranged on the support pile 7 of the temporary trestle. The settlement adjustment mechanism 5 is arranged on the lifting mechanism 4. The other end of the distribution beam 3 is pressed on the lifting mechanism 4. The settlement adjustment mechanism 5 is used to adjust the up-and-down movement of the other end of the distribution beam 3. The butt steel frame 6 is used to pass through the reserved hole of the berthing component, and the butt steel frame 6 can be arranged on the distribution beam 3 and located between the support mechanism 2 and the lifting mechanism 4.

[0038] The fixed clamp 21 of the support mechanism 2 is mounted on the outer wall of the cast-in-place pile 1 by bolts. The support mechanism 2 and the lifting mechanism 4 rely on the cast-in-place pile 1 and the support pile 7 of the temporary trestle respectively to build a double support base point. In cooperation with the distribution beam 3, a span type bearing structure is formed, which can form stable lifting support for the berthing component. Through the bidirectional coordinated adjustment of the height fine adjustment assembly 23 and the settlement adjustment mechanism 5, an adjustable system with independent two ends is constructed. On the one hand, the height fine adjustment assembly 23 is mounted on the fixed clamp 21, which can directly drive the adjustment steel frame 22 to move up and down relative to the fixed clamp 21, thereby adjusting the height of the one end of the distribution beam 3 close to the cast-in-place pile 1. On the other hand, the settlement adjustment mechanism 5 on the lifting mechanism 4 can adjust the up-and-down movement of the one end of the distribution beam 3 close to the support pile 7 of the temporary trestle. Through independent and fine adjustment of the height of the two ends of the distribution beam 3, the horizontal degree of the berthing component on the butt steel frame 6 arranged on the distribution beam 3 can be indirectly and accurately calibrated, and the accuracy and controllability of the horizontal degree adjustment are improved.

[0039] Meanwhile, the lifting mechanism 4 is provided with a settlement adjustment mechanism 5, and the support pile 7 may be slightly elastically compressed or settled after bearing the load, and the support position of the other end of the distribution beam 3 can be secondarily adjusted through the settlement adjustment mechanism 5 after installation, so as to guarantee the installation accuracy of the berthing component.

[0040] In an embodiment, the distribution beam 3, the support mechanism 2, the lifting mechanism 4 and the settlement adjustment mechanism 5 are at least two groups, two groups of support mechanisms 2 are arranged on the opposite sides of two adjacent cast-in-place piles 1 or one cast-in-place pile 1, two groups of lifting mechanisms 4 and settlement adjustment mechanisms 5 are arranged on two adjacent support piles 7 of the temporary trestle or the opposite sides of one support pile 7, and the two ends of the two distribution beams 3 are arranged on the two groups of support mechanisms 2 and the two groups of lifting mechanisms 4 respectively, and the two ends of the butt joint steel frame 6 are arranged on the two distribution beams 3 respectively. The two groups of support mechanisms 2 and the two groups of lifting mechanisms 4 form a double-sided support frame, which facilitates the arrangement of the two ends of the butt joint steel frame 6.

[0041] In an embodiment, the distribution beam 3 includes at least two I-beams, each I-beam 31 is arranged side by side, and the two ends of each I-beam 31 are fixedly connected through a batten 32. The distribution beam 3 includes three I-beams 31 arranged side by side, the I-beams 31 are arranged on the support mechanism 2, the two ends of the I-beams 31 are fixedly welded with the battens 32, the I-beams 31 are welded with a partition plate, and the partition plate is fixedly welded on the battens 32, forming a three-spliced integral structure.

[0042] In an embodiment, the number of the butt joint steel frames 6 is at least two, and each butt joint steel frame 6 is arranged side by side. Specifically, the butt joint steel frame 6 is composed of three groups of two-welded channel steels; the berthing component needs to reserve a reserved hole for the butt joint steel frame 6 to pass through during production, and after the butt joint steel frame 6 passes through the reserved hole on the berthing component, the two ends are arranged on the two distribution beams 3 to realize the horizontal positioning of the berthing component.

[0043] Referring to Figure 2 and Figure 3In an embodiment, an adjusting screw hole is formed on the fixed hoop 21, and a fixed sleeve 232 is connected to the bottom of the fixed hoop 21 and is located opposite to the adjusting screw hole. The height fine adjustment assembly 23 includes an adjusting screw column 231 rotatably connected to the bottom of the adjusting steel frame 22, the adjusting screw column 231 passes through the adjusting screw hole and is screwed into the fixed sleeve 232, and the adjusting steel frame 22 is located above the fixed hoop 21. The adjusting screw column 231 is screwed with the fixed sleeve 232 and the adjusting screw hole, and the adjusting steel frame 22 can be driven to move up and down by rotating the adjusting screw column 231, so that the adjustment accuracy is high. The fixed sleeve 232 is located opposite to the adjusting screw hole, which provides stable guidance for the adjusting screw column 231, avoids the adjusting screw column 231 from being skewed during the adjustment process, ensures the vertical lifting of the adjusting steel frame 22, and improves the support stability. Further, when the position of the adjusting steel frame 22 is adjusted, a pad can be arranged between the adjusting steel frame 22 and the fixed hoop 21, so as to improve the stability of the position of the adjusting steel frame 22.

[0044] Specifically, the top of the adjusting steel frame 22 is provided with a support beam 24, and the support beam 24 is provided with an anti-toppling assembly 25. The anti-toppling assembly 25 includes two fixed supports 251 and two U-shaped plates 252. The two fixed supports 251 are respectively fixed on the two side walls of the distribution beam 3 opposite to each other, and the two U-shaped plates 252 are symmetrically arranged and fixed on the top of the support beam 24. Each fixed support 251 is rotatably arranged in a U-shaped groove of a U-shaped plate 252. The U-shaped groove of the U-shaped plate 252 forms a bidirectional limiting for the two fixed supports 251 on the two sides of the distribution beam 3, which not only prevents the distribution beam 3 from sliding downward, but also limits the lateral deviation of the distribution beam 3. The rotation connection between the fixed support 251 and the U-shaped groove allows the distribution beam 3 to rotate flexibly around the support beam 24, so as to match the posture change requirement when the lifting mechanism 4 lifts and the fine adjustment mechanism 5 adjusts. When the lifting mechanism 4 lifts one end of the distribution beam 3, the distribution beam 3 will rotate correspondingly around the support beam 24, but under the limiting action of the U-shaped plate 252, the position of the distribution beam 3 can be maintained, so as to prevent the distribution beam 3 from sliding downward along the support beam 24.

[0045] Referring to Figure 4 to Figure 6 In an embodiment, the lifting mechanism 4 includes a corbel support 41, a support frame 43, and two limiting frames 44. The corbel support 41 is installed on the outer wall of the support pile 7, the top of the corbel support 41 is provided with the support frame 43, the top of the support frame 43 is symmetrically fixed with the two limiting frames 44, and the other end of the distribution beam 3 is pressed on the support frame 43 and located between the two limiting frames 44. The settlement adjustment mechanism 5 is arranged on the corbel support 41. The corbel support 41 is directly installed on the outer wall of the support pile 7 to form a rigid bearing foundation, and the two symmetrically arranged limiting frames 44 form a lateral constraint space, and the distribution beam 3 is arranged therebetween, so as to effectively limit the axial or lateral sliding of the distribution beam 3 along the support pile 7.

[0046] Specifically, the lifting mechanism 4 includes two bracket supports 41 symmetrically welded and fixed on the outer wall of the support pile 7. A bracket support 42 is fixed between the two bracket supports 41, and a hydraulic lifting mechanism is installed on the bracket support 42 for lifting the other end of the distribution beam 3 to adjust the position and levelness of the distribution beam 3. During the lifting and adjusting process, the limiting frame 44 is used for limiting to prevent the distribution beam 3 and the berthing component from being deflected.

[0047] In an embodiment, the settlement adjusting mechanism 5 includes a lower support 51, an upper support 53, a wedge block 57, and an adjusting frame 60. The lower support 51 is installed on the top of the bracket support 41, the upper support 53 is installed on the lower support 51 and can slide up and down on the lower support 51, the bottom surface of the upper support 53 is formed with a first abutting inclined surface, the adjusting frame 60 is arranged on the lower support 51 and can slide horizontally relative to the lower support 51, the wedge block 57 is fixed on the top of the adjusting frame 60, the top surface of the wedge block 57 is formed with a second abutting inclined surface, and the first abutting inclined surface and the second abutting inclined surface abut and can slide relative to each other. The abutting design of the first abutting inclined surface and the second abutting inclined surface converts the horizontal sliding of the adjusting frame 60 into the vertical lifting of the upper support 53, and the wedge block 57 has the transmission characteristics of small horizontal displacement and micro vertical height, so that millimeter-level height fine adjustment is realized. The adjusting frame 60 is driven to adjust in a horizontal sliding manner, without the need for complex hoisting equipment assistance. Construction personnel can push the adjusting frame 60 by using simple tools such as hammers, crowbars, and jacks to complete height adjustment.

[0048] Specifically, the inclination angles of the first abutting inclined surface and the second abutting inclined surface should satisfy that the tangent value of the inclination angle of the inclined surface cannot exceed the friction coefficient between the first abutting inclined surface and the second abutting inclined surface. After adjustment, mechanical self-locking can be realized through the friction of the inclined surface to avoid the upper support 53 from being retracted due to the weight of the berthing component or wind wave disturbance, and the carrying stability is strong.

[0049] In an embodiment, the friction coefficient between the first abutting inclined surface and the second abutting inclined surface , the friction coefficient between the adjusting frame 60 and the lower support 51 , and the inclination angle of the first abutting inclined surface and the second abutting inclined surface should satisfy the following relationship: .

[0050] Specifically, the friction coefficient between the first abutting inclined surface and the second abutting inclined surface should be greater than or equal to 0.15 to improve the self-locking effect; the friction coefficient between the adjusting frame 60 and the lower support 51 should be greater than or equal to 0.1; and the inclination angle of the first abutting inclined surface and the second abutting inclined surface should be less than or equal to 25 degrees.

[0051] In the embodiment, the first abutting inclined surface of the upper support 53 and the second abutting inclined surface of the wedge-shaped block 57 are both provided with protruding strips. In other embodiments, the first abutting inclined surface and the second abutting inclined surface can be made of wear-resistant materials to avoid the decrease of the friction coefficient due to wear and the destruction of the self-locking condition.

[0052] Specifically, the settlement adjustment mechanism 5 further comprises a support plate 56, a support column 54 is fixed on the upper support 53, a swing steel frame 55 is rotationally connected to the support column 54, and the support plate 56 is installed on the top of the swing steel frame 55. The support plate 56 can abut against the bottom of the distribution beam 3. The support plate 56 is rotationally connected to the support column 54 through the swing steel frame 55, can adapt to the inclination of the angle of the distribution beam 3, ensures that the distribution beam 3 and the support plate 56 are always in surface contact, and prevents stress concentration from causing the distribution beam 3 to break.

[0053] In an embodiment, the lower support 51 is provided with a guide steel strip 52, the upper support 53 is slidably connected to the lower support 51 through the guide steel strip 52, and the top of the lower support 51 is formed with a guide rail. The adjusting frame 60 can slide on the guide rail towards or away from the guide steel strip 52. In the embodiment, the lower support 51 is in an L-shaped structure, one end of the L-shaped lower support 51 is arranged in a vertical state on the corbel support 42, and the other end of the L-shaped lower support 51 is arranged in a horizontal direction on the corbel support 41 to form a horizontally arranged guide rail. The L-shaped lower support 51 is vertically fixed at one end on the corbel support 42 and horizontally laid at the other end on the corbel support 41, and the upper support 53 is slidably connected to the lower support 51 through the guide steel strip 52, so as to ensure that the first abutting inclined surface of the upper support 53 is always accurately matched with the second abutting inclined surface of the wedge-shaped block 57, and the accuracy of height adjustment is improved. The horizontal end of the lower support 51 directly serves as a guide rail, reducing the installation of an additional guide rail component, simplifying the structure and improving the overall load consistency. The L-shaped lower support 51 fully utilizes the installation surfaces of the corbel support 41 and the corbel support 42, and the vertical end and the horizontal end of the L-shaped lower support 51 form a compact layout without occupying redundant space, which is suitable for the narrow working environment of the temporary trestle of the offshore high-pile wharf.

[0054] In an embodiment, the bottom wall of the adjusting frame 60 is connected with an I-shaped sliding block 58, and the guide rail is located between the opposite two flanges of the I-shaped sliding block 58, so that the I-shaped sliding block 58 can drive the adjusting frame 60 and the wedge-shaped block 57 to slide on the guide rail towards or away from the guide steel bar 52. The two side flanges of the I-shaped sliding block 58 form a wrapping clamping structure for the guide rail, and the guide rail is confined between the two flanges. The clamping structure can lock the sliding track, and ensure that the horizontal displacement of the wedge-shaped block 57 can be accurately converted into the vertical lifting of the upper support 53, thereby further improving the height adjustment accuracy of the settlement adjustment mechanism 5. The I-shaped sliding block 58 is perfectly matched with the integrated guide rail of the L-shaped lower support 51, and stable sliding can be achieved without additional installation of a limiting component, thereby simplifying the structure and improving the assembly accuracy. In this embodiment, the I-shaped sliding block 58 can be made of existing I-shaped steel, which has a simple structure and low processing difficulty, and does not require complex positioning tools for assembly with the guide rail. By adjusting the flange spacing and length of the I-shaped sliding block 58, different specifications of the guide rail and the adjusting frame 60 can be adapted, thereby effectively reducing the manufacturing cost.

[0055] Referring to Figure 1 and Figure 2 In an embodiment, the application further discloses a mounting method for a wharf berthing component, which is implemented by using the wharf berthing component counter-pressure mounting device of any one of the above embodiments. Specifically, the mounting method comprises the following steps:

[0056] Step one, install the support mechanism 2 on the cast-in-place pile 1 according to the design elevation position, and install the lifting mechanism 4 on the support pile 7 of the temporary trestle according to the design elevation position. Specifically, before installing the support mechanism 2 and the lifting mechanism 4, use a high-precision total station and a level to accurately measure and set the top elevation line of the installation position on the cast-in-place pile 1 and the support pile 7 of the temporary trestle according to the design elevation, and then install the support mechanism 2 and the lifting mechanism 4 according to the top elevation line.

[0057] Further referring to Figure 3 On the outer wall of the cast-in-place pile 1, two fixed hoops 21 are symmetrically installed by high-strength bolts to form a fixed base of the support mechanism 2, and the support beam 24 welded on the top of the adjusting steel frame 22 is accurately adjusted to the design elevation position by rotating the adjusting stud 231 to drive the adjusting steel frame 22 to move up and down relative to the fixed hoop 21. At the same time, the top heights of the two groups of support beams 24 are ensured to be consistent, and then the U-shaped plate 252 of the anti-toppling assembly 25 is welded and fixed on the top of the support beam 24.

[0058] Referring to Figure 4 and Figure 5 At the same time, on the support pile 7 of the temporary trestle adjacent to the cast-in-place pile 1, two corbel supports 41 and a corbel support 42 connected therebetween are symmetrically welded at the corresponding design elevation position to form a base of the lifting mechanism 4, and a hydraulic jacking mechanism is installed on the corbel support 42.

[0059] Step two, place the two ends of the distribution beam 3 on the support mechanism 2 and the lifting mechanism 4 respectively, check the difference between the actual elevation of the top surface of the distribution beam 3 and the design elevation, if the difference is greater than the preset error, adjust the height fine tuning component 23 of the support mechanism 2 and / or the settlement adjustment mechanism 5 to adjust the position of the distribution beam 3, until the difference between the elevation of the top surface of the distribution beam 3 and the design elevation is controlled within the preset error range. Specifically, adjust the height fine tuning component 23 of the support mechanism 2 to adjust the position of the distribution beam 3. After preliminary positioning, use the level to check the elevation of the top surface until the error between the elevation of the top surface and the design elevation is controlled within ±2mm, and thin steel plates or pads can be placed under the steel frame 22 to stabilize the position of the distribution beam 3.

[0060] Further, place the distribution beam 3 on the top of the support beam 24 and the support frame 43, make the fixed support 251 fixed on the distribution beam 3 slide into the two U-shaped plates 252, and at the same time, the other end of the distribution beam 3 is arranged between the two limiting frames 44, so as to limit the distribution beam 3.

[0061] Step three, pass the butt joint steel frame 6 through the reserved hole of the berthing member, and place the butt joint steel frame 6 on the leveled distribution beam 3. Specifically, pass the butt joint steel frame 6 into the reserved hole on the berthing member, install the level on the top of the berthing member, and place the two ends of the butt joint steel frame 6 on the top of the two groups of distribution beams 3 arranged at intervals, at this time, the whole weight of the berthing member is transmitted to the distribution beam 3 through the butt joint steel frame 6, and is borne by the support beam 24 and the support frame 43 at both ends.

[0062] Step four, detect the actual levelness of the top of the berthing member, if the difference between the actual levelness and the design levelness is greater than the preset difference, adjust the settlement adjustment mechanism 5 until the actual levelness matches the design levelness.

[0063] Specifically, detect the actual levelness of the top of the berthing member, if the difference between the actual levelness and the design levelness is greater than the preset difference, start the hydraulic jacking mechanism on the lifting mechanism 4 to smoothly lift the other end of the distribution beam 3, thereby lifting the berthing member through the butt joint steel frame 6, and cooperating with the level to ensure the levelness of the installation of the berthing member.

[0064] The leveling instrument is erected at a position convenient for observation on the top of the berthing member to detect the actual levelness of the top of the berthing member. If the difference between the actual levelness and the design levelness is greater than a preset difference, the hydraulic jacking mechanism on the bracket support 42 is started to stably lift one end of the distribution beam 3, thereby synchronously and stably jacking the berthing member through the butt joint steel frame 6 and ensuring the levelness of the installation thereof through the leveling instrument. During the jacking process, the measuring personnel real-time monitor the reading change of the leveling instrument on the top of the berthing member to command the operator to slowly and stably perform the jacking operation. When the reading indicates that the top of the berthing member reaches the design elevation, the jacking is immediately stopped. After the jacking is in place, the hydraulic jacking mechanism is removed, and the elevation of the berthing member is rechecked to ensure that no settlement or displacement occurs during the welding and fixing process, and the elevation meets the specification requirements. During the jacking process, the limiting frame 44 prevents the distribution beam 3 from being laterally deflected, and the U-shaped plate 252 of the anti-toppling assembly 25 restricts the fixed support 251 to prevent the distribution beam 3 from sliding down along the support beam 24.

[0065] Further, the pre-assembled settlement adjustment mechanism 5 is integrally installed on the top of the lifting mechanism 4. The adjustment frame 60 is pushed in the horizontal direction to drive the wedge-shaped block 57 to push the upper support 53 to rise along the guide steel bar 52 until the support plate 56 on the top thereof tightly abuts against the distribution beam 3. Then, the hydraulic jacking mechanism is removed to gradually transfer the load of the distribution beam 3 and the berthing member to the support mechanism 2 and the settlement adjustment mechanism 5.

[0066] Then, after the load is transferred, if the position of the berthing member is detected to be lowered, the adjustment frame 60 is again pushed to top up the upper support 53 through the wedge-shaped block 57 to reset the support plate 56 and the distribution beam 3, so that the elevation and levelness of the berthing member return to the design values. After the load is transferred, the structure is compacted at each contact point, the support pile 7 is elastically compressed, which causes the support plate 56 to slightly sink, thereby slightly lowering the position of the berthing member. Then, the adjustment frame 60 is again pushed to top up the upper support 53 through the wedge-shaped block 57 to reset the other end of the support plate 56 and the distribution beam 3, so that the elevation of the berthing member returns to the design values. The adjustment frame 60 can be driven to move in a knocking manner or a pushing manner.

[0067] Finally, the berthing member is fixed on the bored pile 1 in a concrete pouring manner. After the fixing is completed, the support mechanism 2, the distribution beam 3, the lifting mechanism 4 and the settlement adjustment mechanism 5 are removed. After the elevation is confirmed to be correct, the berthing member is fixed on the bored pile 1 in a concrete pouring manner. After the fixing is completed, the support mechanism 2, the distribution beam 3, the lifting mechanism 4 and the settlement adjustment mechanism 5 are removed, and the installation is completed.
