Description

Technical Field

[0001] The utility model relates to the technical field of concrete drainage pipes, in particular to a pressure-resistant socket-and-spigot type reinforced concrete drainage pipe. Background Art

[0002] Concrete pipe is a prefabricated pipe made of concrete or reinforced concrete. It has a wide range of applications. It can effectively discharge sewage and rainwater, prevent various problems caused by drainage problems, and can also transport other fluids such as oil and gas.

[0003] Most of the existing concrete pipes on the market do not have a locking structure, which makes the joints prone to loosening and leakage during use. Some concrete pipes with locking mechanisms have the problem of more troublesome locking. For example, the Chinese utility model patent with announcement number CN220320567U discloses a pressure-resistant socket-type reinforced concrete drainage pipe, which includes a reinforced concrete pipe body, and three fixing holes arranged at equal distances are opened at the edge of the reinforced concrete pipe body; a connecting mechanism for connecting the reinforced concrete pipe body, the connecting mechanism including a connecting seat fixedly connected to the end of the reinforced concrete pipe body, a connecting groove matching the reinforced concrete pipe body is opened on the side of the connecting seat away from the reinforced concrete pipe body, and three fixing components arranged at equal distances are installed at the edge of the connecting seat and corresponding to the positions of the fixing holes. The utility model can not only apply glue inside the connection groove during the connection process to achieve the connection of the reinforced concrete pipe body, but also achieve a stable connection of the reinforced concrete pipe body by setting the clamping action between the fixing bolts and the fixing holes, thereby ensuring the sealing of the reinforced concrete pipe body connection. Although the above device ensures the sealing of the reinforced concrete pipe body connection, in actual use, when connecting the device, the construction personnel are required to align the fixing holes and the fixing bolts, and manually tighten multiple rotating hand wheels. The tightening process is relatively cumbersome, resulting in a large waste of time and manpower, resulting in slow construction and affecting the construction efficiency of the personnel.

[0004] Therefore, it is urgent to provide a pressure-resistant socket-and-spigot reinforced concrete drainage pipe to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a pressure-resistant socket-and-spigot type reinforced concrete drainage pipe.

[0006] In order to solve the above technical problems, the present invention adopts a technical solution: to provide a pressure-resistant socket-and-spigot reinforced concrete drainage pipe, comprising a pipe body and a socket-and-spigot portion, wherein one end of the pipe body is provided with a spigot portion, and the spigot portion is provided with multiple locking mechanisms, and the other end of the pipe body is provided with a spigot portion;

[0007] The exterior of the tube body is provided with reinforcing transverse ribs for enhancing structural strength and improving compression resistance;

[0008] Reinforced vertical ribs are also provided on the outside of the tube body, and the tube body, reinforced transverse ribs and reinforced vertical ribs are an integrated structure.

[0009] The present invention is further configured as follows: the plug-in portion includes a plug connector connected to one end of the tube body, and a plurality of slots are provided on the plug connector, and a sealing ring is fixed to the other end of the plug connector.

[0010] Through the above technical solution, the sizes of the plug joint and the socket part are matched, and the plug joint has a closed-end structure. When laying the pipeline, construction workers can easily connect the plug joint with the socket part, and the sealing ring can effectively prevent water leakage at the connection.

[0011] The utility model is further configured as follows: the locking mechanism includes a threaded pile threadedly connected to the inside of the slot, and a spring is fixed to one end of the threaded pile, and a pin is fixed to the other end of the spring.

[0012] Through the above technical solution, when processing the device, the staff can conveniently fix the spring and the pin to the plug connector through the threaded pile. The spring and the pin form an elastic pin structure, which can conveniently lock the plug-in part and the socket part during subsequent installation. The end of the pin is inclined, and when the end of the pin is under pressure, the pin can naturally retreat into the slot.

[0013] The utility model is further configured as follows: the socket portion includes a socket sleeve fixed to the other end of the pipe body, and the inner wall of the socket sleeve is provided with a pin groove.

[0014] Through the above technical solution, when construction workers connect multiple devices, they can insert the plug connector into the socket sleeve. At this time, the inner wall of the socket sleeve presses the pin, causing the pin to retreat into the slot. When the pin reaches the pin slot, the spring pushes the pin out of the slot. Part of the pin is stuck in the pin slot, and the other part is located in the slot, so that the plug connector and the socket sleeve are connected more tightly and will not loosen or separate.

[0015] The utility model is further configured as follows: a ramp is provided inside the pin groove, and a separation groove is provided at one end of the ramp.

[0016] Through the above technical solution, the number and distance of the separation grooves are matched with the pins, and ramps are set on both sides of the separation grooves. When the device is inspected or replaced, the construction personnel can use the equipment to rotate the device. At this time, the pin will return to the slot under the pressure of the ramp. When the pin is rotated to the separation groove, it will pop out. At this time, the construction personnel can separate the two devices.

[0017] The present invention is further configured as follows: a plurality of the reinforcing transverse ribs and the reinforcing vertical ribs are provided, and the height of the reinforcing transverse ribs is greater than that of the reinforcing vertical ribs.

[0018] Through the above technical solution, the reinforced transverse reinforcement and the reinforced vertical reinforcement can effectively increase the compressive strength of the device, and can also effectively increase the friction of the outer wall of the device. After the earth is backfilled, the friction between the soil and the reinforced reinforcement can effectively prevent the device from being displaced or rotated. At the same time, the reinforced vertical reinforcement can increase the friction between the device and the lifting belt to avoid the device from rotating when the device is lifted. Since the height of the reinforced transverse reinforcement is higher than that of the reinforced vertical reinforcement, the reinforced transverse reinforcement can also prevent the lifting belt from moving to the two ends of the device, effectively improving the safety of construction.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model is equipped with a plug-in part, a locking mechanism and a socket, and the device can be automatically locked after plugging in without additional operation, which effectively reduces the workload of construction workers in laying pipes. In addition, its structure is easy to disassemble and facilitates later maintenance.

[0021] 2. The utility model not only effectively improves the compressive strength of the device by setting up reinforced horizontal reinforcement and reinforced vertical reinforcement, but also prevents the device from displacement and rotation after landfill, and effectively improves the safety during construction.

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] See also Figure 1-Figure 3 A pressure-resistant socket-and-spigot reinforced concrete drainage pipe includes a pipe body 1 and a socket part 4. A plug-in part 2 is provided at one end of the pipe body 1. The plug-in part 2 includes a plug joint 201 connected to one end of the pipe body 1, and a plurality of slots 202 are opened on the plug joint 201. A sealing ring 203 is fixed to the other end of the plug joint 201. The size of the plug joint 201 matches that of the socket part 4, and the plug joint 201 is a closed structure. When laying the pipeline, construction workers can easily connect the plug joint 2 with the socket part 4, and the sealing ring 203 can effectively prevent water leakage at the connection.

[0030] like Figure 1 、 Figure 3 and Figure 4 As shown, a plurality of locking mechanisms 3 are provided on the plug-in part 2, and the locking mechanism 3 includes a threaded pile 301 threadedly connected to the inside of the slot 202, and a spring 302 is fixed to one end of the threaded pile 301, and a pin 303 is fixed to the other end of the spring 302. When processing the device, the staff can conveniently fix the spring 302 and the pin 303 to the plug-in connector 201 through the threaded pile 301. The spring 302 and the pin 303 form an elastic pin structure, which can conveniently lock the plug-in part 2 and the socket part 4 during subsequent installation. The end of the pin 303 is in the shape of a slope, and when the end of the pin 303 is subjected to pressure, the pin 303 can naturally retreat into the slot 202.

[0031] like Figure 1 、 Figure 2 and Figure 5As shown, the other end of the pipe body 1 is provided with a socket part 4, and the socket part 4 includes a socket sleeve 401 fixed to the other end of the pipe body 1, and the inner wall of the socket sleeve 401 is provided with a pin groove 402, and the pin groove 402 is provided with a ramp 403, and one end of the ramp 403 is provided with a separation groove 404. When the construction personnel connect multiple devices, they can insert the plug connector 201 into the socket sleeve 401. At this time, the inner wall of the socket sleeve 401 presses the pin 303, so that the pin 303 retreats into the slot 202. When the pin 303 reaches the pin groove 402, the spring 302 pushes the pin 303 out of the slot 202. Part of the pin 303 is stuck in the pin groove 402, and the other part is located in the slot 202, so that the plug connector 201 and the socket sleeve 401 are connected more tightly without loosening or separation. The number and distance of the separation grooves 404 match the pin 303, and ramps 403 are set on both sides of the separation groove 404. When the device is inspected or replaced, the construction personnel can use the equipment to rotate the device. At this time, the pin 303 will retreat to the slot 202 under the pressure of the ramp 403. When the pin 303 rotates to the separation groove 404, it will pop out. At this time, the construction personnel can separate the two devices.

[0032] like Figure 1 and Figure 2 As shown, the outside of the pipe body 1 is provided with reinforcing transverse ribs 5 for strengthening the structural strength and improving the compressive resistance. The outside of the pipe body 1 is also provided with reinforcing vertical ribs 6. The pipe body 1, the reinforcing transverse ribs 5 and the reinforcing vertical ribs 6 are an integrated structure. There are multiple reinforcing transverse ribs 5 and reinforcing vertical ribs 6, and the height of the reinforcing transverse ribs 5 is greater than the reinforcing vertical ribs 6. The reinforcing transverse ribs 5 and the reinforcing vertical ribs 6 can effectively increase the compressive strength of the device, and can also effectively increase the friction of the outer wall of the device. After the earth is backfilled, the friction between the soil and the reinforcing ribs can effectively prevent the device from being displaced or rotated. At the same time, the reinforcing vertical ribs 6 can increase the friction between the device and the lifting belt to avoid the device from rotating when the device is lifted. Since the height of the reinforcing transverse ribs 5 is higher than the reinforcing vertical ribs 6, the reinforcing transverse ribs 5 can also prevent the lifting belt from moving to the two ends of the device, effectively improving the safety of construction.

[0033] When the present invention is in use, the construction workers first dig a laying groove on the ground, and then use the lifting mechanism to place the pipe body 1 in the laying groove. During the lifting process, the reinforced transverse reinforcement 5 and the reinforced vertical reinforcement 6 can effectively improve the safety of the lifting. Through the plug-in part 2 and the socket part 4, the construction workers can conveniently connect multiple devices, and the locking mechanism 3 can effectively prevent the connection from loosening and falling off. After the laying is completed, the construction workers will backfill the earth. At this time, the reinforced transverse reinforcement 5 and the reinforced vertical reinforcement 6 can also prevent the device from rotating or displacing, and the sealing ring 203 can prevent water leakage at the connection.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
