Description

Technical Field

[0001] This utility model relates to the field of corrugated culvert technology, specifically a metal corrugated culvert that can be directly connected. Background Technology

[0002] Culvert laying and connection is a key process in water conservancy projects, road construction, and municipal drainage systems. Its quality directly affects the safety and durability of the entire project. First, the foundation must be strictly treated before laying to ensure that it is flat, firm, and has sufficient bearing capacity. Usually, a gravel cushion layer needs to be laid and compacted to provide uniform support and prevent the culvert from breaking due to uneven settlement. The socket connection is the most widely used. During operation, the rubber sealing ring is first correctly installed in the groove of the socket. Then, lubricant is applied to the inner wall of the socket and the outer wall of the socket. A special tensioning tool is used to smoothly insert the socket into the socket until the marked line is reached. Ensure that the rubber ring is compressed evenly to form a tight water-stop seal. This connection method has good impermeability and a certain degree of flexibility, and has a strong ability to adapt to small deformations of the foundation. However, most existing connection methods lack initial fixing devices, which means that once the connection is made, the pipe position cannot be changed again. This makes it difficult to quickly change and disassemble the pipe if the position needs to be changed according to the actual situation at the installation site. To avoid the above technical problems, it is necessary to provide a metal corrugated culvert that can be directly connected to overcome the defects in the existing technology. Utility Model Content

A sliding rod 206 is slidably connected to the inner side of the fixing cylinder 205. A positioning piece 207 is welded to one end of the sliding rod 206. A snap-fit ​​spring 208 is sleeved on the outer side of the fixing cylinder 205. One end of the snap-fit ​​spring 208 is spot-welded to the positioning piece 207, and the other end of the snap-fit ​​spring 208 is spot-welded to the connecting plate 202 for easy reset. The inner side of the connecting plate 202 is threaded with a fixing screw 209. One end of the front corrugated culvert 1 is connected to a rear corrugated culvert 210. A fixing nut 211 is welded to one end face of the fixing plate 201. A connecting hole 212 is opened on the inner side of the fixing plate 201 at the position corresponding to the fixing nut 211. Several fixing plates 201 are provided. Several fixing plates 201 are welded at equal angles to one end of the front corrugated culvert 1. Two connecting holes 212 are symmetrically opened on the inner side of the fixing plate 201 to facilitate stable connection. A rear positioning plate 213 is welded to one end of the front corrugated culvert 1, which is the same as the connecting plate 202.

[0016] A sealing assembly 3 is installed on the inner side of the rear corrugated culvert 210; The sealing assembly 3 includes a sealing airbag 301, a mounting groove 302, an inlet pipe 303, an external sealing rubber ring 304, a sealing cap 305, and an inner chamber 306.

An inner cavity 306 is provided inside the rear corrugated culvert 210.

[0017] The working principle and usage process of this utility model are as follows: First, when the operator needs to connect the culverts, the operator first lays the front corrugated culvert 1 to the position to be installed. Then, the operator lifts the rear corrugated culvert 210 and aligns the fixing plate 201 at one end of the rear corrugated culvert 210 with the snap-fit ​​groove plate 203 at one end of the front corrugated culvert 1. Then, the fixing plate 201 can be snapped into the inner side of the snap-fit ​​groove plate 203. At this time, the connecting hole 212 on the inner side of the fixing plate 201 at one end of the rear corrugated culvert 210 will coincide with the sliding rod 206. At this time, under the action of the snap-fit ​​spring 208, the sliding rod 206 will be embedded into the inner side of the connecting hole 212 on the inner side of the fixing plate 201 at one end of the rear corrugated culvert 210, thereby initially connecting and fixing the front corrugated culvert 1 and the rear corrugated culvert 210. If the operator needs to temporarily adjust the position according to the on-site installation situation, simply pull the positioning piece 207 to pull out the sliding rod 206 to disconnect the connection. Then the operator can change the position of the front corrugated culvert 1 and the rear corrugated culvert 210. After determining the position, fix it again by fixing plate 201 and snap-fit ​​groove plate 203. If the installation position is appropriate, the operator can fix all the fixing plates 201 and the rear positioning plate 213 by fixing screws 209 and fixing nuts 211, thereby completely fixing the position of the front corrugated culvert 1 and the rear corrugated culvert 210. Finally, after the positions of the front corrugated culvert 1 and the rear corrugated culvert 210 are fixed, the operator can remove the sealing cap 305 on the outside of the inlet pipe 303. Then, external resin can be injected into the interior of the sealing airbag 301 through the inlet pipe 303. When the sealing airbag 301 is filled, it will fill the gap between the front corrugated culvert 1 and the rear corrugated culvert 210. After the resin solidifies, it can seal the gap between the front corrugated culvert 1 and the rear corrugated culvert 210. The sealing airbag 301 is snapped into the communicating inner cavity 306 of the front corrugated culvert 1 and the rear corrugated culvert 210 to ensure that it can cover the connecting gap and ensure the seal.
