Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reinforced concrete pipes, in particular to a reinforced concrete pipe interface structure. Background Art
[0002] Reinforced concrete drainage pipe is the common cement pipe we know. It has steel bars inside, so it is called reinforced concrete pipe. It is mainly used in drainage systems.
[0003] Most existing reinforced concrete pipes are spliced by first splicing adjacent concrete pipes and then sealing them by pouring mortar. The sealing between adjacent reinforced concrete pipes is only guaranteed by mortar. With long-term use, the mortar will become loose and cracked, causing water in the pipe to leak and corrode. In severe cases, it may even lead to accidents such as road collapse. In addition, although some reinforced concrete pipes use an interface structure with anti-seepage function, the interface is not tight and is in a long-term humid environment underground, which can easily lead to corrosion of the internal structure and cause rupture of the pipe joint. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a reinforced concrete pipe interface structure, which has the advantages of strong waterproofness and strong sealing, and solves the problems of easy water seepage at the pipe opening and easy breakage of some interfaces.
[0005] In order to achieve the above-mentioned purpose of strong waterproofness and strong sealing, the utility model provides the following technical solutions: a reinforced concrete pipe interface structure, comprising a first pipe body and a second pipe body, wherein a connecting mechanism is provided between the first pipe body and the second pipe body;
[0006] The connecting mechanism includes a pouring column and an expansion rubber ring. The pouring column is fixed on the outside of the first tube body, and the expansion rubber ring is fixedly connected to the right side of the first tube body. A steel bar welding block is fixedly installed inside the pouring column, and two pouring ports are opened on the outside of the pouring column.
[0007] Furthermore, the first tube body includes a concrete pipe column, a connecting steel ring and a limiting steel column. The outer portion of the connecting steel ring is fixedly connected to the inner wall of the pouring column, and the expansion rubber ring is provided with holes that are compatible with the two limiting steel columns.
[0008] Furthermore, the left sides of the first tube body and the second tube body are both provided with insertion holes adapted to the limiting steel columns.
[0009] Furthermore, annular guide grooves are provided on both left and right sides of the pouring column, and mortar grooves matching the annular guide grooves are provided on the opposite surfaces of the first tube body and the second tube body.
[0010] Furthermore, the left and right sides of the interior of the pouring column are hollow and are respectively connected to two pouring ports.
[0011] Furthermore, the inner diameter of the pouring column is the same as the diameter of the connecting steel ring.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] 1. The reinforced concrete pipe interface structure is provided with a connection mechanism, and the expansion rubber ring is fixedly installed at the connection between the first pipe body and the second pipe body through a limiting steel column. When the expansion rubber ring contacts water, the shape will change and the surface will expand, which can tightly seal the excess space between the first pipe body and the second pipe body. At the same time, the rubber material also has a strong waterproof performance, which can better seal the connection port and better avoid the occurrence of water seepage. The connection port will be sealed by an external pouring column, so that the waterproof performance is more efficiently improved.
[0014] 2. The reinforced concrete pipe interface structure is provided with a concrete pipe column, a connecting steel ring and a limiting steel column. The connecting steel ring is made of concrete and steel bars and has strong hardness. It can provide relatively stable support for the overall connection port. The limiting steel column is made of pure steel. The two pipe bodies can be effectively connected through the limiting steel column. At the same time, it can also assist the connecting steel ring to bear the weight together, so that the connection mechanism provides stronger stability and better sealing.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 , a reinforced concrete pipe interface structure in this embodiment includes a first pipe body 1 and a second pipe body 2, and a connecting mechanism 3 is provided between the first pipe body 1 and the second pipe body 2;
[0022] The connecting mechanism 3 includes a pouring column 301 and an expansion rubber ring 302. The outside of the first tube body 1 is fixedly connected to the pouring column 301, and the right side of the first tube body 1 is fixedly connected to the expansion rubber ring 302. When the expansion rubber ring 302 comes into contact with water, it will produce object changes and expand on the surface, which can tightly seal the excess space between the first tube body 1 and the second tube body 2. At the same time, the rubber material also has strong waterproof performance, which can better seal the connection port and better avoid the occurrence of water seepage. A steel bar welding block 303 is fixedly installed inside the pouring column 301, and two pouring ports 304 are opened on the outside of the pouring column 301. Cement or mortar materials can be guided into the pouring column 301 through the two pouring ports 304, and the solidification of this material is used to make the connectivity and sealing of the two tubes stronger.
[0023] In the case implementation, the first pipe body 1 includes a concrete pipe column 101, a connecting steel ring 102 and a limiting steel column 103. The outer part of the connecting steel ring 102 is fixedly connected to the inner wall of the pouring column 301. The expansion rubber ring 302 is provided with holes that are compatible with the two limiting steel columns 103, which can provide guidance and positioning functions for the expansion rubber ring 302 when it is installed.
[0024] In the case implementation, the left sides of the first tube body 1 and the second tube body 2 are both provided with sockets adapted to the limiting steel column 103, which can provide guidance and positioning functions when installing the two tube bodies.
[0025] In the case implementation, the left and right sides of the inside of the pouring column 301 are hollow and respectively connected to the two pouring ports 304. The two pouring ports 304 can be used to fill the inside with cement or mortar-like solidifying materials. Annular guide grooves are provided on the left and right sides of the pouring column 301, and the opposite surfaces of the first tube body 1 and the second tube body 2 are provided with mortar grooves that match the annular guide grooves. When the two tube bodies are fixedly connected, the two mortar grooves will be connected to the annular guide grooves on the left and right sides of the pouring column 301, and the annular guide grooves on both sides are connected to their respective hollow parts, so that the cement or mortar-like solidifying materials entering from the two pouring ports 304 can flow into the mortar grooves of the tube bodies at both ends. After the material solidifies, its connectivity and sealing properties will be even stronger.
[0026] In the case implementation, the inner diameter of the pouring column 301 is the same as the diameter of the connecting steel ring 102, which can effectively prevent the internal moisture from seeping.
[0027] When implementing, follow these steps:
[0028] 1) First, fix the pouring column 301 on the outside of the connecting steel ring 102;
[0029] 2) Then the expansion rubber ring 302 is positioned and installed through two limiting steel columns 103;
[0030] 3) Then position and install the two insertion holes on the second tube body 2 and the two limiting steel columns 103;
[0031] 4) Finally, pour cement or mortar-like solidifying materials into the pouring column 301 and the inside of the two pipe bodies through the two pouring ports 304, and wait for them to solidify after they are fully poured.
[0032] In summary, the reinforced concrete pipe interface structure is provided with a connection mechanism 3, and the expansion rubber ring 302 is fixedly installed at the connection between the first tube body 1 and the second tube body 2 through the limiting steel column 103. When the expansion rubber ring 302 contacts water, the shape will change, and the surface will expand, which can tightly seal the redundant space between the first tube body 1 and the second tube body 2. At the same time, the rubber material also has a strong waterproof performance, which can better seal the connection port and better avoid the occurrence of water seepage. Then, the connection port will be sealed by the external pouring column 301, so that the waterproof performance is more efficiently improved, which solves the problem that most of the existing reinforced concrete pipes are spliced by first splicing adjacent concrete pipes and then splicing by pouring mortar to seal. The sealing between adjacent reinforced concrete pipes is only guaranteed by mortar. With long-term use, the mortar will become loose and cracked, causing the water in the pipe to leak and corrode. In severe cases, it will also cause accidents such as road collapse.
[0033] In addition, by setting the concrete pipe column 101, the connecting steel ring 102 and the limiting steel column 103, the connecting steel ring 102 is made of concrete and steel bars, has strong hardness, and can provide relatively stable support for the overall connection port. The limiting steel column 103 is made of pure steel. The limiting steel column 103 can effectively connect the two pipe bodies, and can also assist the connecting steel ring 102 in bearing the weight together, so that the stability provided by the connecting mechanism 3 is stronger and the sealing is better, which solves the problem that although some reinforced concrete pipes adopt an interface structure with anti-seepage function, the internal structure is easily corroded due to the loose connectivity of the interface and it is in a long-term humid underground environment for a long time, which leads to the problem of rupture at the pipe connection.
