[0032] The embodiment of the present application provides a pile foundation reinforcement device for highway bridge construction, such as Figure 1 and Figure 2 As shown, it includes two base plates 100 , two square frames 200 and four arc pads 300 , wherein the base plates 100 are components for supporting and fixing the entire device, the square frames 200 are components for clamping the square pile foundations 010 , and the arc pads 300 are components for clamping the circular pile foundations 020 .

[0033] like Figure 3 As shown, both bottom plates 100 are provided with fixing holes 110, and fixing wedges 120 are inserted into the fixing holes 110. The fixing wedges 120 are inserted into the ground to fix the bottom plates 100 on the ground. In practice, the number of fixing holes 110 is generally multiple to improve the fixing effect.

[0034] like Figure 2 and Figure 4 As shown, two square frames 200 are correspondingly arranged on two bottom plates 100, and one side of the square frame 200 is open to form an open frame structure. Both side walls of the square frame 200 are provided with connecting flanges 210, and the connecting flanges 210 are provided with connecting holes 220. When the connecting flanges 210 are opposite to each other, the connecting holes 220 can realize the installation connection of the two connecting flanges 210.

[0035] like Figure 2 and Figure 5 As shown, two arc pads 300 are detachably connected in each square frame 200, and the two arc pads 300 are respectively located at the upper and lower parts of the square frame 200, and the circular pile foundation 020 can be reinforced from the upper and lower positions. The outer side of the arc pad 300 matches the inner shape of the square frame 200, which is convenient for installing the arc pad 300 into the square frame 200, and the inner side of the arc pad 300 forms a semicircular groove 310, which can match the circular pile foundation 020.

[0036] like Figure 1 and Figure 2 As shown, when the connecting flanges 210 of the two square frames 200 are abutted, the arc pads 300 on the two square frames 200 are abutted, and the two semicircular grooves 310 are connected to form a circular hole, so that the arc pads 300 are tightly clamped on the circular pile foundation 020, and the connecting flanges 210 are connected and fixed by bolts 230 passing through the connecting holes 220.

[0037] When reinforcing the square pile foundation 010, the arc lining block 300 must first be removed, and then the two square frames 200 are clamped on both sides of the square pile foundation 010, the connecting flanges 210 are abutted, and the connection is achieved with bolts 230, and then the bottom plate 100 is tightly fixed to the ground with a fixing wedge 120 to achieve the reinforcement of the square pile foundation 010. When it is necessary to reinforce the circular pile foundation 020, the arc lining block 300 is installed in the square frame 200, and then the two square frames 200 are placed on both sides of the circular pile foundation 020, and the two square frames 200 are abutted, so that the corresponding arc lining blocks 300 are abutted and clamped to the circular pile foundation 020, the connecting flanges 210 are abutted, and the connection is achieved with bolts 230, and then the bottom plate 100 is tightly fixed to the ground with a fixing wedge 120 to achieve the reinforcement of the circular pile foundation 020.

[0038] Compared with the prior art, the pile foundation reinforcement device for highway bridge construction can respectively reinforce the square pile foundation 010 and the circular pile foundation 020 by disassembling and installing the arc liner 300, so that the same device can meet the reinforcement requirements of pile foundations of two shapes. The construction party does not need to manufacture two devices, thereby reducing manufacturing costs.

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the square frame 200 is provided with a mounting hole 240, and the outer side of the arc liner 300 is provided with a threaded shaft 320, the number of the threaded shaft 320 is two, the threaded shaft 320 passes through the mounting hole 240, and is installed and fixed by a nut 330, so that the arc liner 300 can be detachably installed in the square frame 200. The connection method of the threaded shaft 320 and the nut 330 is simple and convenient, and is easy to disassemble and assemble.

[0040] In some embodiments, Figure 4 and Figure 5 As shown, a guide groove 250 is provided on the inner side of the square frame 200, and a guide rib 340 is provided on the outer side of the arc liner 300. The guide rib 340 cooperates with the guide groove 250. Through the guide rib 340 and the guide groove 250, the arc liner 300 can be easily installed with the square frame 200.

[0041] In some embodiments, Figure 5 As shown, an avoidance chamfer 350 is provided at the outer corner of the arc liner 300, so that the outer corner of the arc liner 300 does not need to contact the inner corner of the square frame 200. Sometimes, manufacturing defects or impurities may appear at the inner corner of the square frame 200, affecting the installation of the arc liner 300. By setting the avoidance chamfer 350, manufacturing defects or impurities can be avoided, thereby facilitating the installation of the arc liner 300.

[0042] In some embodiments, Figure 5As shown, a handle 360 ​​is provided on the arc lining block 300, which is convenient for construction workers to take or hoist the lining block and facilitate construction.

[0043] In some embodiments, the semicircular groove 310 of the arc liner 300 has a variety of radius sizes, and the various radius sizes decrease sequentially. That is to say, arc liner blocks 300 of various specifications are provided, and suitable arc liner blocks 300 can be selected according to the size of the circular pile foundation 020, thereby reinforcing circular pile foundations 020 of different diameters, thereby expanding the scope of application of the entire device.

[0044] In some embodiments, Figure 6 As shown, it also includes a square pad group, which includes four square pads 400. Two square pads 400 are installed on each square frame 200. The outer side of the square pad 400 matches the inner side of the square frame 200, and the inner side of the square pad 400 forms a square groove 410. When the two square frames 200 are docked, the two square pads 400 are docked, and the two square grooves 410 form a square hole, which can realize the reinforcement of the square pile foundation 010, and the reinforcement size is smaller than the reinforcement size of the square frame 200. In implementation, the square pad 400 can refer to the arc pad 300, and also set the threaded shaft 320, the guide rib 340 and the handle 360 ​​and other structures to facilitate the installation of the square pad 400 on the square frame 200.

[0045] In some embodiments, there are multiple square liner block groups, and the sizes of the square grooves 410 of the square liner blocks 400 in the multiple square liner block groups are successively reduced to form square liner blocks 400 of various specifications. Suitable square liner blocks 400 can be selected according to the size of the square pile foundation 010 to reinforce the square pile foundations 010 of different sizes, which also expands the scope of application of the entire device.

[0046] In some embodiments, Figure 4 As shown, the base plate 100 is provided with a positioning plate 130 and a positioning groove 140. The positioning plate 130 on one base plate 100 can be inserted into the positioning groove 140 of another base plate 100, so that the two base plates 100 can be docked and positioned, which is convenient for use.

[0047] In some embodiments, Figure 3 As shown, each base plate 100 is provided with three fixing holes 110, and the three fixing holes 110 are evenly distributed on the base plate 100, and adjacent fixing holes 110 are 60 degrees apart. The number of fixing wedges 120 is correspondingly three, and the three fixing wedges 120 can well fix the base plate 100 on the ground, thereby fixing the entire device well on the ground.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
