Two adjacent box culvert bodies 1 are connected by plugging the first plug-in block 2 into the first slot 3; in order to further improve the sealing of the connection (construction joint) between the two box culvert bodies 1, a second plug-in block 4 is fixedly connected in the first slot 3, the cross-section of the second plug-in block 4 is a hollow rectangular frame, and the first plug-in block 2 is provided with a second slot 5 adapted to the second plug-in block 4. After the first plug-in block 2 is inserted into the first slot 3, the second plug-in block 4 is simultaneously plugged into the second slot 5. The first plug-in block 2 and the first slot 3 are plugged in together with the second plug-in block 4 and the second slot 5, providing a multi-layer plug-in structure, thereby improving the connection between the two box culvert bodies 1 The sealing effect of the connection is achieved; in addition, a second positioning hole 21 connected to the inside of the second slot 5 is opened on the inner side of the first plug-in block 2, and the second positioning holes 21 are distributed on the four sides of the inner side of the first plug-in block 2. A third positioning hole 41 adapted to the position and size of the second positioning hole 21 is opened on the second plug-in block 4, and the first plug-in block 2 is detachably connected with a fixing member 6. In this embodiment, the fixing member 6 is detachably connected to the first plug-in block 2 by a bolt 8, and four fixing members 6 are provided, which are respectively located on the four sides of the inner side of the first plug-in block 2. The fixing member 6 is fixedly connected to the side of the fixing member 6 close to the first plug-in block 2 with a second positioning rod 7 adapted to the second positioning hole 21 and the third positioning hole 41. The second positioning rod 7 is inserted into the second positioning hole 21 and the corresponding third positioning hole 41, so that after the first plug-in block 2 is inserted into the first slot 3, the first plug-in block 2 and the second plug-in block 4 can be tightly connected, thereby making the two box culvert bodies 1 tightly connected.

[0027] like Figure 1-5 As shown, one end (front end) of the fixing member 6 located on one side of the first plug-in block 2 protrudes from the opening of the first plug-in block 2, so that the fixing member 6 can cover the fitting connection between the first plug-in block 2 and the first slot 3 after the two box culvert bodies 1 are connected, further improving the sealing effect of the connection between the two box culvert bodies 1.

[0028] like Figure 1-5 As shown, reinforcement blocks 9 are fixedly connected to the four corners of the culvert body 1. The cross-section of the reinforcement blocks 9 is triangular. By providing the reinforcement blocks 9, the structural stability of the corners of the culvert body 1 is improved. In addition, one end (front end) of the reinforcement block 9 located on one side of the first plug-in block 2 protrudes from the opening of the first plug-in block 2 and is flush with the end surface of the fixing member 6. The two ends of the fixing member 6 are respectively adapted to fit the reinforcement blocks 9 on the same side.

[0030] like Figure 1-5 As shown, the culvert body 1 is fixedly connected to a third plug-in block 12 on one side (rear end) of the first slot 3. The cross-section of the third plug-in block 12 is a hollow rectangular frame. The culvert body 1 is provided with a third slot 13 that is compatible with the third plug-in block 12 on one side (front end) of the first plug-in block 2. After the two culvert bodies 1 are connected, the third plug-in block 12 is just inserted into the third slot 13; in addition, a filling slot 14 is provided in the third slot 13, and a filling hole 15 connected to the filling slot 14 is provided on the culvert body 1. A sealant (such as polyurethane foam sealant) is filled into the filling slot 14 through the filling hole 15, so that the connection sealing performance of the third plug-in block 12 and the third slot 13 is improved, thereby improving the connection sealing effect of the two culvert bodies 1.

[0032] The working principle of a novel anti-seepage structure for construction joints of a box culvert in the present embodiment is as follows: when connecting two box culvert bodies 1, align the first plug-in block 2 on the rear box culvert body 1 with the first slot 3 of the front box culvert body 1, or align the first positioning hole 11 with the first positioning rod 10, and insert the first plug-in block 2 into the first slot 3. During the plugging process, the second plug-in block 4 is simultaneously plugged into the second slot 5, and the third plug-in block 12 is inserted into the third slot 13. By plugging and cooperating with the first plug-in block 2 and the first slot 3, the second plug-in block 4 and the second slot 5, and the third plug-in block 12 and the third slot 13, a multi-layer plug-in structure is provided to improve the sealing effect of the connection between the two box culvert bodies 1 and play a role in preventing leakage; the two After the box culvert body 1 is connected, the fixing piece 6 is connected to the first plug block 2 by the bolt 8. At the same time, the second positioning rod 7 is inserted into the second positioning hole 21 and the corresponding third positioning hole 41, so that the two box culvert bodies 1 are tightly connected, and the fixing piece 6 and the reinforcement block 9 cooperate to cover the fitting connection between the first plug block 2 and the first slot 3 after the two box culvert bodies 1 are connected, thereby improving the sealing effect of the connection between the two box culvert bodies 1; finally, fill the filler into the filling groove 14 through the filling hole 15, so that the connection sealing of the third plug block 12 and the third slot 13 is improved, thereby improving the connection sealing effect of the two box culvert bodies 1, and further reducing the probability of leakage at the connection (construction joint) of the two box culvert bodies 1.
