Description

Technical Field

[0001] This utility model relates to the field of socket-type jacking technology, specifically to steel-concrete composite socket-type jacking. Background Technology

[0002] Steel-concrete composite socket-type pipe jacking is a trenchless underground pipeline that combines the advantages of steel and reinforced concrete. It uses cement, steel bars, sand, and gravel as raw materials, mixed and molded in a centrifuge. It is widely used in municipal drainage, water supply, and power projects. However, existing steel-concrete composite socket-type pipe jacking systems have some shortcomings, such as:

[0003] Application No. CN202321845137.8 discloses a steel-socket type reinforced concrete jacking pipe. This equipment facilitates the installation of reinforced concrete jacking pipes by installers, improving the installation efficiency. Secondly, it can buffer the impact force when the reinforced concrete jacking pipe is inserted into the connecting steel ring, preventing the impact during the connection of the reinforced concrete jacking pipe from affecting the overall structural strength of the reinforced concrete jacking pipe. However, in actual use, gaps may appear at the connection between the pipe itself and the connecting pipe, which may lead to pipe leakage during actual use, thereby reducing the sealing performance of the equipment.

[0004] Therefore, we proposed a steel-concrete composite socket-type jacking pipe to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a steel-concrete composite socket-type jacking pipe to solve the problem mentioned in the background art that most composite socket-type jacking pipes on the market may have gaps at the connection between the pipe itself and the connecting pipes, which may lead to pipe leakage in actual use and reduce the sealing performance of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel-concrete composite socket-type jacking pipe, comprising a pipe body and a connection port installed at the right end of the pipe body;

[0007] The pipe body is equipped with a flange on the outside, and a concrete sheath is connected to the right end of the flange. The concrete sheath seals the connection gap between the pipe body and the connection port.

A sealing ring is installed on the inner side of the connection port. The right end of the connection port has a socket, and the socket is fixed to the sealing ring. When the external pipe is connected to the inside of the connection port, it will be connected by the sealing ring, thereby sealing the connection between the connection port and the external pipe.

[0008] By installing a concrete sheath on the outside of the pipe body, the pipe body can be sealed when connected to the connection port, thereby filling the gap between the pipe body and the connection port and increasing the sealing performance of the jacking pipe in actual use. Furthermore, by installing a sealing ring inside the connection port, the connection port can be more secure when connected to the external pipe, and the sealing ring can seal the connection gap between the connection port and the external pipe.

[0009] As a preferred technical solution of this utility model, the pipe body includes an outer pipe, and a buffer layer is provided inside the outer pipe. An inner pipe is connected inside the buffer layer, and the outer pipe is connected to the inner pipe through the buffer layer.

[0011] As a preferred technical solution of this utility model, a steel pipe socket is connected to the left end of the pipe body, and the outer pipe, buffer layer and inner pipe are fixed at the right end of the steel pipe socket.

[0012] The above technical solution enables the optical tube socket to fix the pipe fittings connected to the left end of the pipe body when fixing the components inside the pipe body, thereby increasing the robustness of the device during use.

[0013] As a preferred technical solution of this utility model, the right end of the pipe body is provided with a threaded groove, and the right end of the pipe body is connected to the connection port by the threaded groove to form a threaded fixed connection.

[0014] The above technical solution enables the pipe body to be more stable when connected to the socket, thereby increasing the stability of the equipment during installation.

[0015] As a preferred technical solution of this utility model, three sets of corrugated grooves are installed on the outside of the pipe body, and the outside of the corrugated grooves are in contact with the concrete cladding, thereby increasing the contact area between the pipe body and the concrete cladding for better fixation.

[0016] The above technical solution enables the pipe body to be more firmly bonded and fixed to the concrete cladding, thereby increasing the overall stability of the jacking pipe during use.

[0017] As a preferred technical solution of this utility model, the outer side of the pipe body is fixedly fitted to the flange, and the right end of the flange is provided with a groove, and the flange is connected to the concrete cladding through the groove.

[0018] The above technical solution enables the flange to be more firmly connected to the concrete cladding, thereby increasing the overall robustness of the equipment.

[0019] As a preferred technical solution of this utility model, a reserved steel bar is provided at the left end of the concrete cladding, and a limiting ring is provided on the outside of the pipe body, and the reserved steel bar passes through the flange and is fixedly connected to the limiting ring.

[0020] The above technical solution enables the limiting ring to be fixed by the reserved steel bars, and the limiting ring can support the outside of the pipe body, so that the pipe body can be protected by the limiting ring during installation.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by setting a concrete cladding layer on the outside of the pipe body, the pipe body can be sealed by the concrete cladding layer when connected to the connection port, thereby filling the gap between the pipe body and the connection port, increasing the sealing performance of the jacking pipe in actual use; and by setting a sealing ring inside the connection port, the connection port can be more firmly connected to the external pipe, and the sealing ring can seal the connection gap between the connection port and the external pipe.

[0022] Furthermore, by setting corrugated grooves on the outside of the pipe body, the pipe body can be more firmly bonded and fixed to the concrete cladding, thereby increasing the overall stability of the jacking pipe during use.

[0023] Furthermore, by setting a groove on the right end of the flange, the flange can be more firmly connected to the concrete cladding, thereby increasing the overall robustness of the equipment. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1: To address the problem in the prior art that it is difficult to seal the connection gap between the pipe body 1 and the connection port 5, which may lead to leakage in the pipe jacking equipment, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a steel-concrete composite socket-type jacking pipe, including a pipe body 1 and a connection port 5 installed at the right end of the pipe body 1;

[0034] A flange 2 is provided on the outside of the pipe body 1, and a concrete sheath 4 is connected to the right end of the flange 2. The concrete sheath 4 seals the connection gap between the pipe body 1 and the connection port 5. A concrete extension layer 401 is provided on the right end of the concrete sheath 4, and the inner side of the concrete extension layer 401 is attached to the outside of the connection port 5. A sealing ring 6 is installed on the inner side of the connection port 5. A socket 501 is provided on the right end of the connection port 5, and the socket 501 is attached and fixed to the sealing ring 6. When the external pipe is connected to the inside of the connection port 5, it will be connected by the sealing ring 6, thereby sealing the connection between the connection port 5 and the external pipe.

[0035] Connect the pipe body 1 to the connection port 5, and then fix the concrete sheath 4 to the outside of the pipe body 1 and the connection port 5, so that the gap between the pipe body 1 and the connection port 5 is sealed by the concrete sheath 4. By setting the flange 2 on the outside of the pipe body 1, the flange 2 can fix the left end of the concrete sheath 4, and the concrete extension layer 401 on the right end of the concrete sheath 4 will also be attached and fixed to the outside of the connection port 5.

[0036] The pipe body 1 includes an outer pipe 101, and a buffer layer 102 is provided inside the outer pipe 101. An inner pipe 103 is connected inside the buffer layer 102. The outer pipe 101 is connected to the inner pipe 103 through the buffer layer 102. A steel pipe socket 3 is connected to the left end of the pipe body 1, and the right end of the steel pipe socket 3 fixes the outer pipe 101, the buffer layer 102 and the inner pipe 103.

[0037] The right end of the pipe body 1 is provided with a threaded groove 104, and the right end of the pipe body 1 is connected to the connection port 5 by the threaded groove 104. Three sets of corrugated grooves 105 are installed on the outside of the pipe body 1, and the outside of the corrugated grooves 105 are in contact with the concrete cover 4, thereby increasing the contact area between the pipe body 1 and the concrete cover 4 for better fixation. The outside of the pipe body 1 is fixedly attached to the flange 2, and the right end of the flange 2 is provided with a protrusion 201, and the flange 2 is in contact with the concrete cover 4 through the protrusion 201.

[0038] Example 2: This example discloses another protection method, which differs from Example 1, as follows: Figure 6 Figure 7 As shown, the difference between this embodiment and embodiment 1 is that: the left end of the concrete cladding 4 is provided with a reserved steel bar 7, and the outer side of the pipe body 1 is provided with a limiting ring 8, and the reserved steel bar 7 passes through the flange 2 and is fixedly connected to the limiting ring 8;

[0039] By using the limiting ring 8 to protect the outside of the pipe body 1, the pipe body 1 can be protected from collisions during installation. Furthermore, by setting the reserved steel bar 7 inside the concrete cladding layer 4 and fixing the limiting ring 8 with the reserved steel bar 7, the limiting ring 8 can be fixed more stably, thereby increasing the stability of the equipment during installation.

[0040] Working principle: When using this steel-concrete composite socket-type jacking pipe, first connect the pipe body 1 to the connection port 5. Then fix the concrete sheath 4 to the outside of the pipe body 1 and the connection port 5, so that the gap between the pipe body 1 and the connection port 5 is sealed by the concrete sheath 4. By setting the flange 2 on the outside of the pipe body 1, the flange 2 can fix the left end of the concrete sheath 4. At the same time, the concrete extension layer 401 on the right end of the concrete sheath 4 will also fit and fix to the outside of the connection port 5, so that the connection port 5 is protected by the concrete extension layer 401. When the connection port 5 is connected to the external pipe, the connection between the external pipe can be sealed and fixed by the sealing ring 6 set inside.

[0041] When the left end of the pipe body 1 is connected to the external pipe, the inner pipe 103 will be connected to the external pipe. At the same time, when the outside of the pipe body 1 is subjected to pressure, the outer pipe 101 will transmit the pressure to the buffer layer 102, so that the buffer layer 102 can offset part of the pressure. Furthermore, by setting a groove 201 at the right end of the flange 2, the flange 2 can be fixed to the concrete cladding 4 through the groove 201, thereby increasing the stability of the equipment during installation.

[0042] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
