Description

Technical Field

[0001] The utility model belongs to the technical field of culverts, and particularly relates to a corrugated pipe culvert. Background Art

[0002] In recent years, in the buried structures of projects such as railways, highways, municipal engineering, and mines, as well as in the construction of projects such as the reinforcement of old bridges and culverts, highway tunnels, infiltration wells, and coal mine roadways, a large number of steel corrugated plate assembled structures have been used for construction. The steel corrugated plate is a new type of building structure. It has good ductility and strong anti-deformation ability. At the same time, it is quick and convenient to install, saves construction period, and also has advantages such as low cost and environmental friendliness. It has more advantages than the traditional reinforced concrete structure. It is light in weight and fast in construction, and is superior to the traditional structure both in terms of cost and construction period.

[0003] In modern traffic engineering construction, as an important culvert material, the selection of the splicing method of the corrugated pipe culvert directly affects the quality and service life of the project. Existing corrugated pipe culverts usually adopt circular corrugated pipes made of arc-shaped corrugated steel sheets. As shown in Figure 5 and Figure 6 shown, Figure 5 The connection structure using flange docking includes three circumferentially docked first culvert plate pieces 1'. Adjacent first culvert plate pieces 1' are abutted through a docking steel plate 11', and adjacent docking steel plates 11' are detachably connected by bolts. Figure 6 The connection structure using lapping includes three circumferentially lapped second culvert plate pieces 2'. Adjacent second culvert plate pieces 2' are lapped, and the lapped part between adjacent second culvert plate pieces 2' is detachably connected by two bolts. Figure 5 and Figure 6 The ways of circular corrugated pipes made of arc-shaped corrugated steel sheets both have the problem of easy water seepage. Figure 5 In the connection method in Figure 6 Figure 6 the gaps at the joints of the connection method are of different widths, the water seepage resistance cannot be guaranteed, and it is difficult to deal with the water seepage problem of the culvert in the later stage.

[0036] Both ends of the culvert plate 1 are respectively provided with a first connection portion 21 and a second connection portion 22;

[0037] The first connection portion 21 of any one culvert plate 1 overlaps with the second connection portion 22 of the adjacent culvert plate 1. The first connection portion 21 of any one culvert plate 1 overlaps outside the second connection portion 22 of the adjacent culvert plate 1. A bolt 2 is detachably connected at the overlapping portion of the first connection portion 21 of any one culvert plate 1 and the second connection portion 22 of the adjacent culvert plate 1, and a waterproof cavity 3 is formed at the overlapping portion of the first connection portion 21 of any one culvert plate 1 and the second connection portion 22 of the adjacent culvert plate 1;

[0038] A sealing strip is arranged in the waterproof cavity 3.

[0039] As a preferred solution, the first connection portion 21 includes a first outer steel plate 211 and a first inner steel plate 212. The first outer steel plate 211 is fixedly connected to the outer side wall of the culvert plate 1 and is located at one end edge position of the culvert plate 1. The first outer steel plate 211 is perpendicular to the culvert plate 1;

[0040] The first inner steel plate 212 is fixedly connected to the inner side wall of the culvert slab 1. The first inner steel plate 212 and the first outer steel plate 211 are spaced apart. The first inner steel plate 212 is arranged perpendicular to the inner side wall of the culvert slab 1.

[0041] The second connecting portion 22 includes a second outer steel plate 221 and a second inner steel plate 222. The second inner steel plate 222 is fixedly connected to the inner side wall of the culvert slab 1 and is located at the edge position of the other end of the culvert slab 1. The second inner steel plate 222 is arranged perpendicular to the culvert slab 1;

[0042] The second outer steel plate 221 is fixedly connected to the outer side wall of the culvert slab 1. The second outer steel plate 221 and the second inner steel plate 222 are spaced apart. The second outer steel plate 221 is arranged perpendicular to the outer side wall of the culvert slab 1;

[0043] The first outer steel plate 211 abuts against the second outer steel plate 221. The first outer steel plate 211 and the second outer steel plate 221 are detachably connected by bolts 2;

[0044] The first inner steel plate 212 abuts against the second inner steel plate 222. The first inner steel plate 212 and the second inner steel plate 222 are detachably connected by bolts 2;

[0045] A waterproof cavity 3 is formed by enclosing the first inner steel plate 212, the second outer steel plate 221, any one of the culvert slabs 1 and the adjacent culvert slab 1.

[0046] Such as Figure 4As shown, several bolts 2 are arranged in an array along the length direction of the culvert slab 1 on the first outer steel plate 211 and the second outer steel plate 221; that is, several bolts 2 distributed in an array are detachably connected along the axial direction of the culvert; several bolts 2 are arranged in an array along the length direction of the culvert slab 1 on the first inner steel plate 212 and the second inner steel plate 222. In this embodiment, nine bolts 2 are arranged along the length direction of the culvert slab 1. That is, several bolts 2 distributed in an array are detachably connected along the axial direction of the culvert. In this embodiment, mounting holes are oppositely arranged on the first outer steel plate 211, the first inner steel plate 212, the second outer steel plate 221 and the second inner steel plate 222. When the first outer steel plate 211 abuts against the second outer steel plate 221, the mounting holes on the first outer steel plate 211 and the second outer steel plate 221 are oppositely distributed for the bolt 2 to pass through the mounting holes and detachably connect the first outer steel plate 211 and the second outer steel plate 221 together through the bolt 2. When the first inner steel plate 212 abuts against the second inner steel plate 222, the mounting holes on the first inner steel plate 212 and the second inner steel plate 222 are oppositely distributed for the bolt 2 to pass through the mounting holes and detachably connect the first inner steel plate 212 and the second inner steel plate 222 together through the bolt 2. At this time, a waterproof cavity 3 is formed by enclosing the first inner steel plate 212, the second outer steel plate 221, any one of the culvert slabs 1 and the adjacent culvert slab 1. Since the first inner steel plate 212 and the first outer steel plate 211 are spaced apart, and the second outer steel plate 221 and the second inner steel plate 222 are spaced apart, the overlapping force arm of the first connecting portion 21 of any one of the culvert slabs 1 and the second connecting portion 22 of the adjacent culvert slab 1 is increased and the force-bearing area is increased, thereby increasing the force-bearing capacity of the culvert on the surface and reducing the load on the bolt 2, making the corrugated culvert more firm.

[0047] As a preferred solution, the sealing strip 4 is a rubber sealing strip 4. The sealing strip 4 is filled in the waterproof cavity 3. By using the rubber sealing strip 4 to fill the waterproof cavity 3, the waterproof cavity 3 can be effectively sealed and moisture penetration can be prevented due to the good elasticity and close-fitting characteristics of the rubber sealing strip 4, having high anti-seepage performance.

[0048] In other embodiments, the sealing material of the sealing strip 4 can adopt polyethylene foam material, natural rubber, neoprene, EVA foam board or weather-resistant sealant, etc.

[0049] The working mode of the present utility model is as follows:

[0050] In use, a culvert is formed by circumferentially overlapping three culvert plate pieces 1 to form a tubular structure. Specifically, first, a sealing strip 4 is placed on the outer wall of the second connecting portion 22 of the culvert plate piece 1. The sealing strip 4 is located between the second outer steel plate 221 and the second inner steel plate 222, that is, within the waterproof cavity 3. By overlapping the first connecting portion 21 of any culvert plate piece 1 on the outside of the second connecting portion 22 of the adjacent culvert plate piece 1, the culvert is formed by circumferential overlapping in sequence. The first outer steel plate 211 is abutted against the second outer steel plate 221, and the first outer steel plate 211 and the second outer steel plate 221 are detachably connected by bolts 2. At the same time, the first inner steel plate 212 is abutted against the second inner steel plate 222, and the first inner steel plate 212 and the second inner steel plate 222 are detachably connected by bolts 2. At this time, the sealing strip 4 is filled in the waterproof cavity 3 surrounded by the first inner steel plate 212, the second outer steel plate 221, any culvert plate piece 1 and the adjacent culvert plate piece 1. Since the first inner steel plate 212 and the first outer steel plate 211 are spaced apart, and the second outer steel plate 221 and the second inner steel plate 222 are spaced apart, the width of the waterproof cavity 3 along the circumference of the culvert has a certain length. As a result, the water seepage sealing part of the culvert in this solution is wider, and the waterproof sealing part is not damaged by the bolts 2 during installation, so that the water seepage problem of the steel corrugated culvert is well solved, and the waterproof effect is better.

[0051] In this embodiment, by filling the sealing strip 4 into the waterproof cavity 3 according to this solution, it is convenient to conduct a water seepage test on the waterproof cavity 3 of the culvert. When water seepage occurs at a certain place, waterproof glue can be injected into the waterproof cavity 3 by drilling a hole at that place. Specifically, the waterproof glue uses neutral silicone structural glue, which further well solves the water seepage problem of the steel corrugated culvert, is convenient for subsequent water seepage treatment, and has a better waterproof effect.

[0052] The above has introduced the present utility model in detail. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
