Description

Technical Field

[0001] This utility model relates to the field of bridge jacking construction technology, specifically to a follow-up support device for bridge jacking construction. Background Technology

[0002] Currently, bridge jacking technology has been widely applied, with hydraulic cylinder jacking being a common construction method, especially in large-tonnage bridge jacking projects, where hydraulic jacking is the standard choice.

[0003] During bridge jacking construction, it is often necessary to continuously add shims to adjust the support height in order to achieve the required lifting height. However, in practice, the existing support method has obvious defects. When adding shims, due to the unstable contact between the shims and between the shims and the support surface, the shims are prone to displacement or tilting under the force of bridge jacking. Once this happens, it will not only affect the accuracy and progress of bridge jacking construction, but more seriously, it may lead to safety accidents, posing a great threat to the lives of construction workers and the stability of the bridge structure. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a follow-up support device for bridge jacking construction, so as to solve the problem that the existing technology is prone to displacement or tilting when adding pad blocks to increase the lifting height, which may lead to safety accidents.

[0005] According to an embodiment of this utility model, a follow-up support device for bridge jacking construction includes a base plate; columns are provided at both ends of the base plate, and a first protrusion is provided at the top of each column; multiple sets of pads are stacked sequentially on the corresponding column, wherein a notch is opened at the bottom of each column, and the corresponding notch abuts against the corresponding first protrusion; a second protrusion is provided at the top of each column, and each second protrusion abuts against the corresponding notch; and a horizontal detection unit is detachably installed on the base plate for detecting the horizontality of the base plate.

[0006] Compared to existing technologies, this invention offers the following advantages: The first protrusion at the top of the column abuts against the notch at the bottom of the adjacent column, while the second protrusion at the top of the column engages with the notch at the bottom of the upper column. This interlocking design effectively restricts the horizontal movement of the stacked pads, significantly enhancing the overall stability of the stacked pads and reducing the risk of safety accidents caused by pad displacement or tilting. The structure is simple and clear, easy for construction workers to understand and operate, and effectively improves construction efficiency. Furthermore, the horizontal detection unit allows for real-time monitoring of the base plate's levelness. During bridge jacking, if the base plate shows signs of tilting, construction workers can promptly detect it and take immediate corrective measures to ensure the entire support device remains horizontal and stable. This prevents uneven stress on the pads due to an uneven base plate, thus providing crucial protection for construction safety.

[0007] Preferably, a T-shaped groove is provided at the top of the column and at the top of each pad, and a first T-shaped block is provided at the bottom of each pad, with the first T-shaped block slidably disposed in the corresponding T-shaped groove.

[0008] Preferably, each pad has a slot on top for placing a jack.

[0009] Preferably, a rectangular through groove is provided on the bottom plate, and the rectangular through groove is located between the two columns.

[0010] Preferably, the horizontal detection unit includes an L-shaped column and a second T-shaped block fixedly disposed at one end of the L-shaped column. An installation groove is provided on the side wall of the rectangular through groove, and the second T-shaped block is engaged in the installation groove. A suspension rope is provided at the end of the L-shaped column away from the second T-shaped block, and a detection arm is provided at one end of the suspension rope. A support arm is provided on the L-shaped column, and a reference ring is provided at one end of the support arm. The detection arm passes through the reference ring.

[0011] Preferably, each pad has a weight-reducing groove.

[0012] Preferably, each column is provided with a flange at its bottom. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a follow-up support device for bridge jacking construction, which includes a base plate 1; columns 12 are provided at both ends of the base plate 1, and a first protrusion 122 is provided on the top of each column 12; multiple sets of pads 2, each pad 2 is stacked on the corresponding column 12 in sequence, wherein a notch 26 is opened at the bottom of each column 12, the corresponding notch 26 abuts against the corresponding first protrusion 122, and a second protrusion 21 is provided on the top of each column 12, and each second protrusion 21 abuts against the corresponding notch 26; a level detection unit is detachably installed on the base plate 1 for detecting the levelness of the base plate 1.

[0020] The detailed working process of this embodiment is as follows: the first protrusion 122 set on the top of the column 12 abuts against the notch 26 at the bottom of the adjacent column 12, and the second protrusion 21 on the top of the column 12 cooperates with the notch 26 at the bottom of the upper column 12. This interlocking structure design can effectively restrict the horizontal movement of the pad 2 when stacking pads, greatly enhance the overall stability of the stacked pads 2, and reduce the risk of safety accidents caused by the displacement or tilting of the pads 2. The structure is simple and clear, easy for construction personnel to understand and operate, and can improve construction efficiency.

[0021] In use, the active jack 101 and the follower jack 102 are placed in the placement slots 22 on the top of each pad block 2. The placement slots 22 can accurately position the jacks and prevent them from being horizontally displaced during the bridge jacking process, so that the jacks are subjected to more stable and accurate force direction when applying jacking force.

[0022] Simultaneously, with the horizontal detection unit in place, the levelness of the base plate 1 can be detected in real time. During the bridge jacking process, if the base plate 1 shows any tendency to tilt, the construction personnel can promptly detect it and take measures to adjust it, ensuring that the entire support device is in a horizontal and stable state. This prevents the pad blocks 2 from tilting due to uneven force caused by the unevenness of the base plate 1, thus providing an important guarantee for construction safety.

[0023] like Figure 2As shown, a T-shaped groove 123 is provided on the top of the column 12 and the top of each pad 2, and a first T-shaped block 24 is provided on the bottom of each pad 2. The first T-shaped block 24 is slidably disposed in the corresponding T-shaped groove 123.

[0024] The detailed working process of this embodiment is as follows: The sliding engagement between the T-slot 123 and the first T-block 24 provides good support and positioning for the pad block 2 in the vertical direction, ensuring precise alignment of the pad block 2 during stacking and effectively preventing misalignment in the vertical direction. In the horizontal direction, the interlocking relationship formed by the T-shaped structure restricts the lateral movement of the pad block 2, greatly enhancing the overall stability of the stacked pad blocks 2. During the bridge jacking process, even under significant pressure and lateral force, the pad block 2 is not prone to displacement or tilting, significantly reducing the probability of safety accidents.

[0025] The design of the first T-block 24 sliding within the T-slot 123 makes the installation and removal of the pad 2 very convenient. When adjusting the lifting height or increasing or decreasing the number of pads 2, construction workers only need to align the first T-block 24 of the pad 2 with the T-slot 123 and gently push it in or pull it out. No complicated tools or cumbersome procedures are required, which can effectively improve construction efficiency.

[0026] like Figure 3 As shown, each pad 2 has a placement groove 22 on its top for placing the jack.

[0027] The detailed working process of this embodiment is as follows: With the placement slot 22, the placement slot 22 provides a dedicated installation position for the jack, which can accurately position the jack and prevent it from horizontally displacing during the bridge jacking process. The precise positioning of the jack by the placement slot 22 makes the force direction of the jack more stable and accurate when applying jacking force.

[0028] like Figure 2 As shown, a rectangular through groove 11 is provided on the base plate 1, and the rectangular through groove 11 is located between the two columns 12.

[0029] The detailed working process of this embodiment is as follows: by opening a rectangular through groove 11 on the base plate 1, the amount of material used in the base plate 1 is reduced, the weight of the entire support device is reduced to a certain extent, which is conducive to the transportation and handling of the support device and reduces costs.

[0030] like Figure 4As shown, the horizontal detection unit includes an L-shaped column 3 and a second T-shaped block 31 fixedly installed at one end of the L-shaped column 3. An installation groove 13 is provided on the side wall of the rectangular through groove 11. The second T-shaped block 31 is engaged in the installation groove 13. A suspension rope 33 is provided at the end of the L-shaped column 3 away from the second T-shaped block 31. A detection arm 34 is provided at one end of the suspension rope 33. A support arm 32 is provided on the L-shaped column 3. A reference ring 321 is provided at one end of the support arm 32. The detection arm 34 passes through the reference ring 321.

[0031] The detailed working process of this embodiment is as follows: Through the cooperation of the reference ring 321 and the detection arm 34, when the base plate 1 is in a horizontal state, the detection arm 34 will pass vertically through the reference ring 321. Once the base plate tilts, the detection arm 34 remains vertical due to gravity, resulting in a relative offset between it and the reference ring 321. Construction personnel can visually determine whether the base plate 1 is horizontal by observing the relative positional relationship between the detection arm 34 and the reference ring 321, promptly detect any tilting of the base plate 1, and quickly take measures to adjust it, ensuring the stability of the support device and guaranteeing the safe progress of the bridge jacking construction.

[0032] The second T-block 31 is fixed to the base plate 1 by engaging with the mounting groove 13. During installation, simply align the second T-block 31 with the mounting groove 13 and push it in to complete the fixation. Disassembly is done in reverse, without the need for additional tools, which is convenient and quick.

[0033] like Figure 3 As shown, each pad 2 has a weight-reducing groove 25.

[0034] The detailed working process of this embodiment is as follows: the weight reduction groove 25 directly reduces the weight of a single pad 2 by removing some of the material in non-critical load-bearing areas.

[0035] like Figure 1 As shown, each column 12 has a flange 121 at its bottom.

[0036] The detailed working process of this embodiment is as follows: Under the action of flange 121, it can be connected to external support components to ensure stability.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
