[0002] Non-pressure box culvert water delivery is a common drainage mode in water conservancy projects, and cement box culverts are widely used in water conservancy projects due to their flexible construction and low cost.

[0003] Cement box culverts are generally made into square box culverts for convenience during construction, and are easily damaged during long-term use or water disasters. When repairing the cement box culvert, the damaged part of the box culvert is generally removed and a new cement box culvert is constructed or a metal box culvert is used to replace the damaged cement box culvert. Although the cost of rebuilding the cement box culvert is relatively low, it takes a long time to solidify when setting up the steel support and pouring cement during construction. This method is not suitable for emergency repair of water conservancy projects.

[0004] Therefore, in order to repair the damaged pipeline conveniently and quickly, we propose a water stop structure of horizontal construction joint of underground box culvert. CONTENT OF THE UTILITY MODEL

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1 to 5 The present application provides a technical solution:

[0033] A water stop structure of an underground box culvert horizontal construction joint, comprising two left and right cement box culverts 1, wherein the cement box culvert 1 is a square structure, and a square structure through hole is formed from the left side to the right side, as shown in Figure 1 and Figure 2 .

[0034] Then a metal pipe box culvert 2 is arranged between the two left and right cement box culverts 1, wherein the metal pipe box culvert 2 is a cylindrical structure with a hollow cavity inside, and both ends are through structures, as shown in Figure 2 .

[0035] Secondly, the left and right ends of the metal pipe box culvert 2 are fixedly installed with connecting heads 3, wherein one end of the connecting head 3 fixedly connected with the metal pipe box culvert 2 is in a circular structure, and the other end away from the metal pipe box culvert 2 is in a square structure, and the square structure can be slidably installed in the through hole of the square structure of the cement box culvert 1, as shown in Figure 1 .

[0036] Therefore, in use, the square end of the connecting head 3 is slidably installed in the cement box culvert 1, and then the metal pipe box culvert 2 is fixedly installed between the left and right connecting heads 3 by welding, so that the left and right cement box culverts 1 are in a through state under the action of the connecting head 3 and the metal pipe box culvert 2.

[0037] Thus, under the action of the above structure, the staff can quickly repair the damaged box culvert pipeline, save repair time, and ensure the smoothness of the pipeline.

[0038] Secondly, the position where the metal pipe box culvert 2 and the connecting head 3 are fixedly connected is in a welded state, and after welding is completed, it will be in contact with moisture in the air, thereby causing oxidation and decay at the welded position during use, thereby causing leakage at the welded position. Therefore, in order to ensure that the welded position will not leak.

[0039] Therefore, the position where the metal pipe box culvert 2 and the connecting head 3 are welded is externally installed with an upper buckle 4 and a lower buckle 5, wherein the opening position of the upper buckle 4 and the lower buckle 5 is externally provided with an aligned hexagonal screw hole 6, and when the upper buckle 4 and the lower buckle 5 are aligned, a matching double-headed screw 7 is slidably installed in the hexagonal screw hole 6, wherein the upper and lower ends of the double-headed screw 7 are circular structure screws, and the middle position is in a matching state with the hexagonal screw hole 6. Finally, nuts 8 are rotatably installed at the upper and lower ends of the double-headed screw 7, so that the upper buckle 4 and the lower buckle 5 are in a fixed state, so that the welded position will not be in contact with moisture in the air, thereby ensuring that the welded position will not be oxidized, and avoiding the leakage of the welded position.

[0040] Working principle: first, clean the damaged box culvert, then slidably install the connecting head 3 in the cement box culvert 1, then the operator can fill the foaming agent or use the asbestos expansion cement to fill the sliding installation position of the cement box culvert 1 and the connecting head 3, realize the sealing operation of the sliding position of the connecting head 3 and the cement box culvert 1, avoid the leakage of the sliding installation position, as shown in Figure 5 .

[0041] Then, the metal pipe box culvert 2 is fixedly installed between the left and right connecting heads 3 by welding, thereby completing the repair work.

[0042] Second, let the upper buckle 4 and the lower buckle 5 combination together to protect the position of the welding, using double head screw rod 7 slidingly installed in the inside of the hexagonal screw hole 6, and then using the nut 8 and the upper and lower ends of the double head screw rod 7 to rotate and connect, let the upper buckle 4 and the lower buckle 5 tightly combine together.

[0043] It should be noted that the upper and lower ends of the double head screw rod 7 are cylindrical structures located outside the hexagonal screw hole 6.

[0044] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
