[0003] Recycled concrete reinforced concrete tongue and groove pipes are made primarily from recycled concrete and steel, using a tongue and groove connection method. They are mainly used in urban drainage, culverts, and other engineering fields. Sometimes, recycled concrete reinforced concrete tongue and groove pipes are installed as vertical drainage pipes. However, these pipes generally do not have climbing mechanisms. When operators need to enter the area below the pipes for maintenance, they need to use additional equipment, which is cumbersome. This not only increases the time cost of operation but may also lead to excessive physical exertion for operators due to frequent handling and assembly of auxiliary equipment, thus affecting work efficiency and safety.

[0004] Therefore, this utility model provides a recycled concrete tongue-and-groove pipe that is easy to climb, in order to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reclaimed concrete reinforced concrete tongue-and-groove pipe for easy climbing, comprising a tongue-and-groove pipe body, wherein connecting columns are symmetrically embedded in a longitudinal array on the inner surface of the tongue-and-groove pipe body, one end of each connecting column extends into the interior of a connecting groove, the connecting groove is longitudinally arrayed on the surface of an installation frame facing the connecting column, bolts are connected through the two surfaces of the installation frame, one end of each bolt is connected through a limiting hole, the limiting hole is opened through one side surface at the front end of the connecting column, the other end of each bolt is connected to a fixing hole on the outer surface, the fixing hole is opened on one side surface inside the connecting groove, climbing rods are fixedly connected in a longitudinal array on the inner surface of the installation frame, a threaded ring is connected to one side surface of the installation frame outside the bolts, and a threaded cap is threadedly connected to the outer surface of the threaded ring.

[0007] As a preferred embodiment of the present invention, a reclaimed concrete tongue-and-groove pipe with reinforced concrete that is easy to climb, the mounting frame is connected to the connecting column by means of a connecting groove.

[0008] As a preferred embodiment of the present invention, which is a reclaimed concrete tongue-and-groove pipe for easy climbing, the position and size of the limiting hole match the position and size of the fixing hole, and the bolt forms a threaded connection by passing through the limiting hole and the fixing hole.

[0009] As a preferred embodiment of the recycled concrete tongue-and-groove pipe for easy climbing according to this utility model, the top surface of the climbing pole is connected with protrusions in a rectangular array.

[0010] As a preferred embodiment of the present invention, a tongue-and-groove pipe made of recycled concrete that is easy to climb, a sealing ring is connected around the outer surface of the front end of the connecting column, one end of the sealing ring is engaged with the inside of the sealing groove, and the sealing groove is opened on the inner surface of the connecting groove.

[0011] As a preferred embodiment of the present invention, a tongue-and-groove pipe made of recycled concrete that is easy to climb, the inner side surface of the threaded cover is connected to a sealing gasket, one side surface of the sealing gasket is in contact with the threaded ring, and the outer side surface of the threaded cover is provided with grooves in a ring array.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the interlocking of connecting columns, mounting frames, bolts, climbing rods, and protrusions to create a climbing frame inside the tongue and groove pipe body. When operators need to access the area beneath the pipe body for maintenance, they can move along the mounting frame by holding and stepping on the climbing rods at different positions. This allows for convenient climbing within the pipe body without the need for additional equipment, thus facilitating maintenance operations.

[0014] This invention utilizes the cooperation of a sealing ring, a threaded ring, a threaded cover, and a sealing gasket. The sealing ring increases the seal between the connecting column and the mounting frame, preventing external air from entering the connecting groove and contacting the bolt's threaded portion. When the threaded cover is screwed onto the threaded ring, the sealing gasket is pressed together with the threaded ring, thereby increasing the seal between the threaded cover and the threaded ring and preventing external air from entering the threaded ring and contacting the bolt's head. This reduces environmental corrosion of the bolt and ensures the bolt's stability during use. Attached Figure Description

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.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a reclaimed concrete tongue and groove pipe for easy climbing, comprising a tongue and groove pipe body 1, wherein connecting posts 2 are symmetrically embedded in a longitudinal array on the inner surface of the tongue and groove pipe body 1, one end of the connecting posts 2 extends into the interior of the connecting groove 3, the connecting groove 3 is longitudinally arrayed on the end surface of the mounting frame 4 facing the connecting posts 2, bolts 5 are connected through the two sides of the mounting frame 4, one end of the bolts 5 is connected through the limiting hole 6, the limiting hole 6 is opened through one side surface at the front end of the connecting posts 2, the other end of the bolts 5 is connected to the outer surface of the fixing hole 7, the fixing hole 7 is opened on one side surface inside the connecting groove 3, climbing rods 8 are fixedly connected in a longitudinal array on the inner surface of the mounting frame 4, a threaded ring 12 is connected to one side surface of the mounting frame 4 outside the bolts 5, and a threaded cover 13 is threadedly connected to the outer surface of the threaded ring 12.

[0023] Preferably, the mounting frame 4 is connected to the connecting column 2 via the connecting groove 3.

[0024] In actual use, the mounting frame 4 can slide on the connecting column 2 through the connecting groove 3, so that the mounting frame 4 can be slidably placed or separated. The mounting frame 4 and the connecting column 2 are made of metal.

[0025] Preferably, the position and size of the limiting hole 6 match the position and size of the fixing hole 7, and the bolt 5 forms a threaded connection by passing through the limiting hole 6 and the fixing hole 7.

[0026] In practical use, when one end of the connecting column 2 is slidably inserted into the connecting groove 3 on the mounting frame 4, the limiting hole 6 on the connecting column 2 will also move to the position of the fixing hole 7. At this time, the bolt 5 is inserted through the limiting hole 6 and screwed into the fixing hole 7, so that one end of the connecting column 2 can be fixed in the connecting groove 3, and the connecting column 2 and the mounting frame 4 can be fixedly connected together.

[0027] Preferably, the top surface of the climbing pole 8 has a rectangular array of protrusions 9 connected together.

[0028] In actual use, the climbing pole 8 and the protrusion 9 are made of metal. The protrusion 9 can increase the friction between the operator's hands and feet and the climbing pole 8, allowing the operator to hold the climbing pole 8 more steadily and climb, and the feet can find a better foothold during the climbing process.

[0029] Preferably, a sealing ring 10 is connected around the outer surface of the front end of the connecting column 2, and one end of the sealing ring 10 is engaged with the interior of the sealing groove 11, which is located on the inner surface of the connecting groove 3.

[0030] In practical use, when one end of the connecting post 2 is slidably inserted into the connecting groove 3 on the mounting frame 4, the sealing ring 10 on the connecting post 2 will also move to the position of the sealing groove 11, so that the sealing ring 10 is elastically engaged in the sealing groove 11, thereby increasing the sealing between the connecting post 2 and the mounting frame 4 and preventing external air from entering the connecting groove 3. The sealing ring 10 is made of rubber.

[0031] Preferably, a sealing gasket 14 is connected to one side of the inner surface of the threaded cover 13, and one side of the sealing gasket 14 is in contact with the threaded ring 12. The outer surface of the threaded cover 13 has grooves 15 arranged in a ring array.

[0032] In practical use, when the threaded cover 13 is screwed onto the threaded ring 12, the sealing gasket 14 on the inner side of the threaded cover 13 will be pressed together with one end of the threaded ring 12. This increases the sealing between the threaded cover 13 and the threaded ring 12, preventing external air from entering the threaded ring 12. The groove 15 on the threaded cover 13 increases the friction between the operator's hand and the threaded cover 13, making it easier for the operator to rotate the threaded cover 13. The sealing gasket 14 is made of rubber.

[0033] Working principle: In manufacturing this easy-to-climb recycled concrete reinforced concrete tongue and groove pipe, the pipe body 1 is cast in a designated mold using recycled concrete and steel as the main raw materials. During the manufacturing process, the connecting post 2 needs to be embedded in the pipe body 1, so that the connecting post 2 is fixedly connected to the pipe body 1. At this time, one end of the connecting post 2 will protrude from the inside of the pipe body 1. Then, a limiting hole 6 and a connecting sealing ring 10 are opened at the designated position of the connecting post 2. Then, one end of the connecting post 2 is slidably placed into the connecting groove 3 on the mounting frame 4. At this time, the seal on the connecting post 2 is activated. Ring 10 will engage with the sealing groove 11, thereby improving the seal between the connecting post 2 and the mounting frame 4. At the same time, the limiting hole 6 on the connecting post 2 will move to the position of the fixing hole 7. Then, the bolt 5 is passed through one side surface of the mounting frame 4, and the other end of the bolt 5 is passed through the limiting hole 6 and screwed into the fixing hole 7. At this time, one end of the connecting post 2 will be fixedly connected to the mounting frame 4. The tongue and groove pipe body 1 will then be equipped with a climbing mounting frame 4. When the tongue and groove pipe body 1 is installed in the designated position for use, the operator needs to enter the lower part of the tongue and groove pipe body 1 for maintenance. At this time, the operator only needs to hold and step on the climbing poles 8 at different positions to move on the installation frame 4, allowing the operator to climb to the bottom of the tongue and groove pipe body 1 for maintenance operations. This setting allows the operator to move to the bottom of the tongue and groove pipe body 1 without the need for additional equipment, thus facilitating the maintenance operation. Secondly, after the bolt 5 is installed, the head of the bolt 5 will be inside the threaded ring 12. Then, the threaded cover 13 is screwed onto the threaded ring 12, allowing the sealing gasket 14 inside the threaded cover 13 to... When pressed against one end of the threaded ring 12, the sealing gasket 14 increases the sealing between the threaded cover 13 and the sealing gasket 14. At this time, the sealing ring 10 can prevent external air from entering the connecting groove 3 and contacting the threaded part of the bolt 5, while the threaded cover 13 can prevent external air from entering the threaded ring 12 and contacting the head of the bolt 5. In this way, the bolt 5 is less likely to come into contact with external air, thereby reducing the corrosion of the bolt 5 by the environment, improving the service life of the bolt 5, ensuring the stability of the bolt 5 during use, and allowing the mounting frame 4 and the connecting column 2 to be stably connected together for use.
