DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-3 This patent provides a technical solution: a box culvert structure that is easy to dock, including a box culvert body 1, a positioning convex ring 2 is installed on the right side wall of the box culvert body 1, and a positioning groove 3 is opened on the left side wall of the box culvert body 1. Several box culvert bodies 1 can be docked end to end through the cooperation between the positioning convex ring 2 and the positioning groove 3;

[0022] By providing the positioning convex ring 2 and the positioning groove 3, on the one hand, the two box culvert bodies 1 can be more accurately butted together when being butted together, thereby improving the accuracy of butt jointing; on the other hand, the two box culvert bodies 1 can be more tightly sealed after being connected;

[0023] A support plate 4 is installed on the lower wall of the culvert body 1, and the support plate 4 is located below the positioning groove 3. A slide groove 5 is opened on the upper wall of the support plate 4. A clearance groove 6 is opened on the lower wall of the culvert body 1. The clearance groove 6 is located below the positioning convex ring 2. The support plate 4 can be inserted into the clearance groove 6. A fixing block 7 is installed on the inner wall of the clearance groove 6. The fixing block 7 is inserted into the slide groove 5, and the fixing block 7 can slide in the slide groove 5;

[0024] In order to prevent the soil from being clamped between the two box culvert bodies 1 when they are docked, the device is provided with a support plate 4 on the side wall of the box culvert body 1, and the support plate 4 is used to block the soil, so that when docking, the box culvert body 1 is directly placed on the support plate 4, and the fixing block 7 is inserted into the slide groove 5, and the box culvert bodies 1 are docked together through the guidance of the slide groove 5. During the docking process, the box culvert body 1 does not contact the soil, thereby preventing the soil from affecting the sealing of the connection between the two box culvert bodies 1;

[0025] A sealing ring 8 is fitted on the side wall of the positioning convex ring 2;

[0026] The sealing ring 8 can further improve the sealing performance of the two culvert bodies 1 after being connected to avoid water leakage.

[0027] Specifically, the sealing ring 8 includes a rubber ring 81 and a convex ring 82. The convex ring 82 is fitted on the side wall of the positioning convex ring 2. The rubber ring 81 is fitted on the outer side of the convex ring 82. The side wall of the accommodating groove 6 is provided with an annular groove 9. The convex ring 82 can be inserted into the annular groove 9.

[0028] The sealing ability of the sealing ring 8 can be further improved by providing the convex ring 82 .

[0029] Specifically, a steel cage 10 is provided inside the box culvert body 1, connection holes 11 are provided at the four corners of the side wall of the box culvert body 1, and a mounting groove 12 is provided on the inner wall of the box culvert body 1. There are four mounting grooves 12 in total, and the four mounting grooves 12 are respectively connected to the four connecting holes 11;

[0030] In this article, when the box culvert body 1 is prefabricated, the steel cage 10 is first placed in a mold, and then concrete is filled into the mold. After solidification, the box culvert body 1 is obtained;

[0031] After the box culvert main body 1 is butt-jointed, it is necessary to connect and fix the box culvert main body 1 through fine-rolled threaded steel bars. One end of the fine-rolled threaded steel bar is inserted into the connecting hole 11 from the mounting groove 12 and passed through the mounting groove 12 in the other box culvert main body 1. Then, threaded steel connectors are arranged at both ends of the fine-rolled threaded steel bars, and the threaded steel bars are locked to complete the butt-jointing and fixation of the two box culvert main bodies 1.

[0032] Specifically, a ball groove 13 is formed on the inner wall of the slide groove 5, and a ball 14 is rotatably installed in the ball groove 13, and the ball 14 can fit with the lower wall of the fixed block 7;

[0033] By arranging the ball bearings 14 in the slide groove 5, the friction between the fixing block 7 and the slide groove 5 can be reduced when the culvert body 1 is docked.

[0034] Specifically, the four corners of the upper wall of the culvert body 1 are equipped with lifting rings 15, which can be connected to external lifting ropes;

[0035] The provision of the lifting ring 15 can make it convenient to lift the box culvert body 1 and move the box culvert body 1 to a designated installation position by an external crane.

[0036] Specifically, the lifting ring 15 includes a connecting rod 151, a ring body 152, a threaded hole 153 and a bolt 154. One end of the connecting rod 151 is installed at the four corners of the upper wall of the culvert body 1, and the other end of the connecting rod 151 is installed with the ring body 152. The upper wall of the ring body 152 is provided with a threaded hole 153, and a bolt 154 is rotatably installed in the threaded hole 153. The bolt 154 can suppress the external lifting rope;

[0037] The bolt 154 can be used to suppress the suspension rope to prevent it from moving or falling off.

[0038] Working principle: The box culvert body 1 is moved to the installation position by an external crane and a lifting rope, and the fixing block 7 under the positioning convex ring 2 of the box culvert body 1 is inserted into the slide groove 5. The box culvert body 1 is docked together under the guidance of the slide groove 5. During the docking process, the box culvert body 1 does not contact the soil, thereby preventing the soil from affecting the sealing of the connection between the two box culvert bodies 1.

[0039] After the two culvert bodies 1 are butt-jointed, the convex ring 82 in the sealing ring 8 will be inserted into the annular groove 9, so as to further improve the sealing performance between the connection of the two culvert bodies 1;

[0040] After the two box culvert bodies 1 are butt-jointed, they can be fixed by external threaded steel bars.
