AI Technical Summary
In the existing prefabricated box culvert connection nodes, the gap between the protrusions and grooves is small during the pouring process, which makes pouring inconvenient and the structure unstable.
The first outer shell contacts the second outer shell, and the first inner shell contacts the second inner shell. Concrete is filled through fixing holes and fixed with a cover plate. An arc-shaped plate is inserted into the groove to increase stability.
This method effectively fills and limits the concrete within the box culvert, improving the structural stability of the connection nodes.

[0002] The assembly type box culvert structure connecting joint refers to the joint position for connecting different prefabricated components in the assembly type box culvert construction. The box culvert structure is usually used in underground pipeline, traffic tunnel, drainage system and other projects, and the assembly type design can improve construction efficiency and reduce on-site construction time. In the existing box culvert assembly and fixing process, most methods are to use connecting plate, steel bar connection, concrete pouring and other structure connecting joints to fix the box culvert. In the concrete pouring method, the convex block and the recess groove of the box culvert are aligned and then poured. However, in actual application, this method is relatively troublesome. Firstly, when the box culvert is assembled, the two box culverts need to be closely attached, which leads to a relatively small gap between the convex block and the recess groove. In the pouring process, the pouring needs to be carried out step by step along the gap. Secondly, the box culvert is fixed by concrete solidification alone, and the structure is not very stable. Therefore, an assembly type box culvert structure connecting joint is needed to solve the above problems. SUMMARY

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example
[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a prefabricated box culvert structure connection node, including a first box culvert 1 and a second box culvert 4. A first outer shell 2 is fixedly sleeved on the outer surface of the first box culvert 1, and a first inner shell 3 is fixedly connected to the inner wall of the first box culvert 1. A second outer shell 5 is fixedly sleeved on the outer surface of the second box culvert 4, and a second inner shell 6 is fixedly connected to the inner wall of the second box culvert 4. Concrete is filled between the first box culvert 1 and the second box culvert 4.
[0020] The outer surface of the first inner shell 3 is slidably connected to the inner wall of the second box culvert 4, and the inner wall of the second outer shell 5 is slidably connected to the outer surface of the first box culvert 1.
[0021] The top of the second outer shell 5 is provided with a fixing hole 7, and a cover plate 8 is slidably connected to the inner wall of the fixing hole 7. The cover plate 8 is fixedly connected to the inner wall of the fixing hole 7 by concrete.
[0022] In the above embodiment, the first outer shell 2 contacts the second outer shell 5, and the first inner shell 3 contacts the second inner shell 6. At this time, there is a gap between the first box culvert 1 and the second box culvert 4. Concrete is then poured through the fixing hole 7 to fill the gap between the first box culvert 1 and the second box culvert 4. The first inner shell 3 and the second inner shell 6 prevent the concrete filling the gap between the first box culvert 1 and the second box culvert 4 from entering the interior of the first box culvert 1 and the second box culvert 4. The first outer shell 2 and the second outer shell 5 prevent the concrete filling the gap between the first box culvert 1 and the second box culvert 4 from entering the exterior of the first box culvert 1 and the second box culvert 4, thereby limiting the concrete. Then, the cover plate 8 enters the interior of the fixing hole 7, and the concrete of the first box culvert 1 and the second box culvert 4 is solidified and fixed. Thus, the fixing hole 7 is used to fix the first box culvert 1 and the second box culvert 4.
[0023] Multiple curved plates 9 are fixedly connected to one side of the first box culvert 1;
[0024] The second box culvert 4 has multiple grooves 10 on one side;
[0025] The outer surface of the arc plate 9 is slidably connected to the inner wall of the groove 10, and the arc plate 9 is fixedly connected to the inner wall of the groove 10 by the filling concrete.
[0026] Through the above embodiments, after the first outer shell 2 contacts the second outer shell 5 and the first inner shell 3 contacts the second inner shell 6, the arc plate 9 will enter the interior of the groove 10. When the concrete is filled, the concrete will flow into the interior of the groove 10 by gravity and diffusion, and at the same time, it will wrap the arc plate 9. After the concrete solidifies, the arc plate 9 can further increase the structural stability of the node between the first box culvert 1 and the second box culvert 4.
[0027] Working principle:
[0028] like Figures 1-4 As shown, during use, the first outer shell 2 contacts the second outer shell 5, and the first inner shell 3 contacts the second inner shell 6. At this time, there is a gap between the first box culvert 1 and the second box culvert 4. Simultaneously, the arc-shaped plate 9 enters the interior of the groove 10. Concrete is then poured through the fixing hole 7, filling the space between the first box culvert 1 and the second box culvert 4. The first inner shell 3 and the second inner shell 6 prevent the concrete filling the space between the first box culvert 1 and the second box culvert 4 from entering their interiors. The first outer shell 2 and the second outer shell 5 prevent the concrete from being filled into the first box culvert 1 and the second box culvert 4. The concrete between culvert 1 and culvert 4 will not be outside the first culvert 1 and the second culvert 4, thus limiting the concrete. Then, it enters the interior of the fixing hole 7 through the cover plate 8. At this time, the concrete of the first culvert 1 and the second culvert 4 is solidified and fixed. Thus, the first culvert 1 and the second culvert 4 can be fixed at the fixing hole 7. The concrete will flow into the interior of the groove 10 by gravity and diffusion, and at the same time, it will wrap the arc plate 9. After the concrete solidifies, the arc plate 9 can further increase the structural stability of the joint between the first culvert 1 and the second culvert 4.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
