[0002] When constructing on a bridge surface, after completing the asphalt concrete work on one side of the bridge surface, it is necessary to construct on the other side. In order to avoid damaging the already constructed side of the road surface during the construction process, it is usually necessary to erect a barrier at the edge of the completed area to separate the constructed area from the area to be constructed, thereby protecting the completed asphalt pavement.

[0003] The conventional method of erecting retaining walls involves drilling holes in the concrete bridge deck or asphalt concrete pavement, inserting reinforcing bars or steel rods for support and fixation, and then repairing the damaged concrete bridge deck or asphalt concrete pavement after construction is complete. This method of fixing retaining walls is complex, and the repaired areas are highly susceptible to pavement defects, posing safety and quality risks.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0013] As a further optimized technical solution, the length extension direction of the fixed seat is arranged parallel to the length extension direction of the protective baffle.

[0014] As a further optimized technical solution, the two ends of the tie structure have through holes for fitting onto the first column and the second column, respectively. The first column and the second column are detachably connected with stop components for connecting the tie structure to the first column and the second column, respectively.

[0015] As a further optimized technical solution, both the first and second columns have threads on their outer sides, and the stop component is a nut.

[0016] As a further optimized technical solution, the tie structure consists of multiple tie rods, with each tie rod having its two ends connected to a first column and a second column, respectively.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] This utility model provides a bridge protection device suitable for paved asphalt pavement. By fixing the protective baffle on a fixed pad and setting a support unit with stable support performance, the protective baffle can be stably placed on one side of the completed asphalt pavement, thereby forming an effective isolation from the pavement to be constructed. This allows for the protection of the constructed asphalt pavement without damaging the pavement.

[0027] Example 1

[0028] like Figure 1 , Figure 2 As shown, the bridge protection device applicable to paved asphalt pavement includes a protective baffle 1 for forming an isolation, a fixing plate 2 for fixing the protective baffle 1, and a support unit set on the fixing plate 2 for maintaining the isolation state of the protective baffle 1.

[0029] The fixing plate 2 is made of steel plate and is fixedly installed at the bottom of the protective baffle 1 and arranged perpendicular to the protective baffle 1. The fixing plate 2 can increase the contact area between the protective baffle 1 and the ground, thereby increasing the stability of the protective baffle 1 in the upright state.

[0030] The support unit has a first support structure and a second support structure arranged opposite to each other. The first support structure is vertically fixed to the fixed pad 2 by welding. The second support structure is used to be placed on the completed asphalt pavement 9. A tie structure is provided between the first support structure and the second support structure. The tie structure, together with the first support structure and the second support structure, is used to maintain the stable isolation state of the protective baffle 1.

[0031] In this embodiment, the first support structure includes a plurality of first columns 3 arranged at intervals along the length extension direction of the fixed pad 2, and the second support structure includes a fixed base 4 made of I-beams. The length extension direction of the I-beams is parallel to the length extension direction of the protective baffle 1. The two end faces of the I-beams are arranged vertically. A plurality of second columns 5 are fixedly connected to the connecting plate connecting the two end faces of the I-beams by welding. The second columns 5 are arranged parallel to the first columns 3. The tie structure is used to connect the first columns 3 and the second columns 5 laterally.

[0032] Specifically, the two ends of the tie structure have through holes for fitting onto the first column 3 and the second column 5, respectively. The first column 3 and the second column 5 are detachably connected to a stop component 6 for connecting the tie structure to the first column 3 and the second column 5, respectively.

[0033] In this embodiment, both the first column 3 and the second column 5 have threads on their outer sides, the stop component 6 is a nut, and the tie structure consists of multiple tie rods 7. Both ends of any tie rod 7 are connected to a first column 3 and a second column 5, respectively. That is, the through hole at one end of any tie rod 7 is fitted onto a first column 3, and the through hole at the other end is fitted onto a second column 5. Nuts are then threaded onto the first column 3 and the second column 5, respectively, to stop and limit the tie rod 7. Specifically, the tie rods 7 can be arranged along the direction perpendicular to the protective baffle 1, or inclined, or a combination of both arrangements, thereby making the support unit more stable.

[0034] In addition, the bridge protection device suitable for asphalt pavement also includes a stop block 8, which is movably mounted on the fixed pad 2. One end of the stop block 8 abuts against the side of the protective baffle 1, and the other end abuts against the side of the completed asphalt pavement 9. This further increases the stability of the support unit. The stop block 8 is available in several different sizes, such as... Figure 2As shown, for positions on the fixed pad 2 where the first column 3 is not installed, a slightly longer stop block 8 can be used, so that one end of the stop block 8 abuts against the side of the protective baffle 1, and the other end directly abuts against the side of the completed asphalt pavement 9. For positions on the fixed pad 2 where the first column 3 is installed, a shorter stop block 8 is needed. Two stop blocks 8 are spliced ​​together, with one stop block 8 placed between the protective baffle 1 and the first column 3, and the other stop block 8 placed between the first column 3 and the completed asphalt pavement 9, avoiding interference from the first column 3, and jointly providing support for the side of the completed asphalt pavement 9 and the side of the protective baffle 1. Furthermore, the distance between the protective baffle 1 and the completed asphalt pavement 9 can be adjusted by adjusting the number of stop blocks 8 installed along the direction perpendicular to the protective baffle 1.

[0035] When using this device, first place the second support structure on the completed asphalt pavement 9, then place the fixing pad 2 with the protective baffle 1 fixed on the bridge pavement 10, and then operate to install the connecting tie rod 7. After all the tie rods 7 are installed in place, adjust the distance between the protective baffle 1 and the completed asphalt pavement 9 by placing the stop block 8.

[0036] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
