Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipelines, and particularly relates to a reinforced concrete steel socket pipe with a protection effect. Background Technique

[0002] Precast steel socket concrete pipes are widely used in urban utility tunnels. The steel socket concrete pipe is a kind of reinforced concrete pipe made of cement, steel bars, sand, stones, etc. and formed by centrifugal stirring. It can be used for drainage, underground cable layout, pedestrian passages, etc. Its application makes more reasonable use of the urban underground space.

[0003] At present, the Chinese patent with the publication number CN215568638U discloses a reinforced concrete socket pipe, belonging to the technical field of municipal pipeline construction. It includes a pipe body, and the two ends of the pipe body are respectively provided with a socket end and a spigot end that are mutually adapted. An axial limiting part one is arranged on the socket end, and an axial limiting part two that is rotationally adapted to the connection one is arranged on the spigot end. By rotating two adjacent socket pipes by a certain angle, under the action of the axial limiting part one and the axial limiting part two, the installation effect of the two socket pipes can be achieved, that is, even when there is an axial action after the installation is completed later, relative movement will not occur, thereby ensuring the normal sewage discharge effect of the pipeline.

[0004] The above-mentioned reinforced concrete socket pipe still has some problems in use. It is necessary to rotate two adjacent socket pipes by a certain angle to achieve the installation effect of the two socket pipes. However, to rotate it, it is necessary to excavate a certain distance to both sides on both sides of the socket pipe. When in a limited excavation area, the distance between the two sides of the reinforced concrete socket pipe is relatively narrow, which is not convenient for the staff to rotate it, so the applicability is poor. Content of the Utility Model

DETAILED DESCRIPTION

[0023] 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.

[0024] Please refer to Figures 1-4 , this embodiment provides a reinforced concrete steel socket pipe with a protective effect, including a reinforced concrete steel socket pipe body 100. A socket pipe 102 is fixedly connected to the top of the reinforced concrete steel socket pipe body 100. A clamping member for connecting the reinforced concrete steel socket pipe body 100 is arranged on the surface of the socket pipe 102. A socket and spigot 103 is opened at the lower mouth of the reinforced concrete steel socket pipe body 100;

[0025] The clamping member includes receiving grooves 204 opened on both side surfaces of the socket pipe 102. The inner cavities of the two receiving grooves 204 are both slidably connected with first wedge-shaped blocks 203. The inclined surfaces of the two first wedge-shaped blocks 203 are both slidably connected with a second wedge-shaped block 200. The bottoms of the two first wedge-shaped blocks 203 are both fixedly connected with ejector rods 205. One ends of the two ejector rods 205 respectively penetrate downward through the reinforced concrete steel socket pipe body 100 and extend into the inner cavity of the socket and spigot 103. An annular clamping groove 104 corresponding to the second wedge-shaped block 200 is opened on the inner wall surface of the socket and spigot 103. Through the arrangement of the clamping member, the ejector rod 205 in the socket and spigot 103 is jacked upward. At the same time, the ejector rod 205 jacks the first wedge-shaped block 203 upward, so as to jack the second wedge-shaped block 200 in contact with the inclined surface of the first wedge-shaped block 203 outward, and clamp the second wedge-shaped block 200 in the annular clamping groove 104 of the first group of reinforced concrete steel socket pipe bodies 100, thereby enhancing the connection strength between two adjacent reinforced concrete steel socket pipe bodies 100. And the clamping structure can bear a certain amount of tensile force and pressure, ensuring that two adjacent reinforced concrete steel socket pipe bodies 100 will not be easily separated during use, thereby preventing the liquid in the reinforced concrete steel socket pipe body 100 from leaking out. At the same time, it is convenient to connect two adjacent reinforced concrete steel socket pipe bodies 100 together, which can adapt to different installation environments and working conditions requirements, and improves the applicability of the reinforced concrete steel socket pipe body 100.

[0026] Furthermore, a sealing gasket 101 is fixedly connected to the mouth of the socket pipe 102. The sealing gasket 101 is obliquely arranged at the mouth of the socket pipe 102. Through the arrangement of the sealing gasket 101, it effectively prevents liquid from leaking at the connection part, improves the sealing performance, and the obliquely arranged sealing gasket 101 can play a guiding role when the socket pipe 102 is inserted, making the insertion process smoother.

[0027] Furthermore, limiting grooves 207 are provided on the inner walls on both sides of the two sets of accommodation grooves 204. A limiting block 206 is slidably connected to the inner cavity of the limiting groove 207. The two sets of limiting blocks 206 on the same side are fixedly connected to the corresponding side surfaces of the second wedge-shaped blocks 200 at the corresponding positions. Through the arrangement of the limiting groove 207 and the limiting block 206, the second wedge-shaped block 200 is prevented from deviating from the predetermined track during the sliding process, ensuring the accuracy and stability of the clamping connection, reducing connection failures caused by the misalignment of the second wedge-shaped block 200, and improving the reliability of the device.

[0028] Preferably, rollers 202 are rotatably connected to the inclined surfaces of the two sets of first wedge-shaped blocks 203. Square grooves 201 are provided at positions corresponding to the rollers 202 on the inclined surfaces of the two sets of second wedge-shaped blocks 200. The surface of the roller 202 contacts the bottom inner wall of the square groove 201. Through the arrangement of the roller 202, the rotation of the roller 202 can greatly reduce the sliding friction between the first wedge-shaped block 203 and the second wedge-shaped block 200, making the clamping process smoother and more labor-saving.

[0029] It is known that a plurality of groups of rubber rings 105 are inlaid on the inner wall of the socket 103 and near the mouth of the reinforced concrete steel socket pipe body 100. Through the arrangement of the rubber rings 105, the sealing performance between the socket pipe 102 and the socket 103 is further improved, preventing leakage. And the rubber rings 105 can play a certain buffering role, avoiding direct collision between the socket 103 and the socket pipe 102 when the reinforced concrete steel socket pipe body 100 is subjected to external impact, and preventing damage from occurring at the edges of the socket 103 and the socket pipe 102, thereby improving the impact resistance of the reinforced concrete steel socket pipe body 100.

[0030] Furthermore, a protective layer 106 is sprayed on the surface of the reinforced concrete steel socket pipe body 100, where the protective layer 106 is one or a combination of epoxy resin, polyurethane, polytetrafluoroethylene, and non-woven fabric. A hydrophilic layer 107 is provided on the inner wall surface of the reinforced concrete steel socket pipe body 100, where the hydrophilic layer 107 is one or a combination of ultra-high molecular weight polyethylene, carbon fiber composite material, and nano-silica. Through the arrangement of the protective layer 106 and the hydrophilic layer 107, the protective layer 106 can prevent the reinforced concrete steel socket pipe body 100 from being affected by external factors such as corrosion and wear, and has a certain anti-explosion property, extending the service life of the reinforced concrete steel socket pipe body 100. And the hydrophilic layer 107 can make the liquid flow more smoothly on the inner wall of the reinforced concrete steel socket pipe body 100, reducing resistance and the accumulation of attachments.

[0031] Working principle;

[0032] First, a group of reinforced concrete steel socket pipes 100 are hoisted into the excavated trench and placed in the trench. Subsequently, a second group of reinforced concrete steel socket pipes 100 are hoisted into the trench, and the socket pipes 102 at their tops are aligned with the socket openings 103 of the previous group of reinforced concrete steel socket pipes 100. Then, a pipe jacking machine is used to insert the socket pipes 102 at the tops into the socket openings 103 of the previous group of reinforced concrete steel socket pipes 100. Subsequently, a third group is hoisted into the trench, and the pipe jacking machine is used to insert the socket pipes 102 of the third group of reinforced concrete steel socket pipes 100 into the socket openings 103 of the second group of reinforced concrete steel socket pipes 100. When the socket pipes 102 are inserted into the socket openings 103, the sealing gaskets 101 installed at the tops of the socket pipes 102 first contact the inner walls of the socket openings 103 and simultaneously contract inward, making the outer surfaces of the sealing gaskets 101 closely adhere to the inner cavities of the socket openings 103. While the socket pipes 102 move along the socket openings 103, the ejector rods 205 in the socket openings 103 are jacked upward, and at the same time, the first wedge blocks 203 are jacked upward, thereby jacking the second wedge blocks 200 in contact with the inclined surfaces of the first wedge blocks 203 outward, and the second wedge blocks 200 are clamped into the annular slot 104 of the first group of reinforced concrete steel socket pipes 100, thus clamping the first group of reinforced concrete steel socket pipes 100 and the second group of reinforced concrete steel socket pipes 100 together, improving the connection strength between adjacent two groups of reinforced concrete steel socket pipes 100.
