Therefore, reinforced concrete pipe jacking is widely used in urban underground pipeline systems.

[0003] However, the existing reinforced concrete jacking pipe has the following problems when used:

[0004] For example, a reinforced concrete jacking pipe with a publication number of CN219933159U and an authorization announcement date of 20231031, in which adjacent pipes are sealed only by a single sealing ring when connected, resulting in insufficient sealing between the pipes, which can easily lead to pipe leakage and affect the normal use of the reinforced concrete jacking pipe.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original reinforced concrete jacking pipe. Utility Model Content

[0006] The utility model aims to provide a reinforced concrete jacking pipe to solve the problem that the existing reinforced concrete jacking pipe is not sufficiently sealed, which may easily lead to pipeline leakage and affect the normal use of the reinforced concrete jacking pipe.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforced concrete jacking pipe, comprising a pipe body, an outer protective ring is fixedly connected to the outer wall of the end of the pipe body, and an inner clamping ring is fixedly arranged on the inner wall of the end of the pipe body on the side of the outer protective ring, an inner sleeve is fixedly installed on the inner wall of the end of the pipe body away from the outer protective ring, and a first sealing ring is bonded to the surface of the inner sleeve, and a second sealing ring is fixedly connected to the end face of the pipe body on the side of the inner sleeve, the outer wall of the pipe body is sleeved with a connecting sleeve, and a positioning bolt is movably connected to the inner wall of the connecting sleeve.

[0008] Preferably, the outer protective ring and the connecting sleeve are respectively fitted with the second sealing ring, and the outer protective ring and the connecting sleeve are threadedly connected.

[0009] Preferably, the inner retaining ring and the inner retaining sleeve are slidably arranged.

[0010] Preferably, the inner retaining ring and the first sealing ring are arranged in close contact with each other.

[0011] Preferably, the connecting sleeve and the tube body form a sliding structure.

[0012] Preferably, the positioning bolts are respectively threadedly arranged with the connecting sleeve and the tube body, and the positioning bolts are symmetrically distributed about the transverse center axis of the tube body.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the reinforced concrete jacking pipe has enhanced sealing performance, thereby preventing pipeline leakage from affecting the normal use of the reinforced concrete jacking pipe;

[0014] Through the movement of the pipeline, the inner clamping ring on the pipeline is sleeved onto the outside of the inner clamping ring on the adjacent pipeline, and as the pipeline moves, the inner clamping ring slides along the inner clamping ring and finally fits with the first sealing ring. At this time, the second sealing ring is squeezed between the adjacent pipelines, so that the pipeline is sealed by the first sealing ring and the second sealing ring. Therefore, the sealing performance of the pipeline is enhanced, thereby preventing pipeline leakage from affecting the normal use of the reinforced concrete jacking pipe.

[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 1-4The utility model provides a technical solution: a reinforced concrete jacking pipe, comprising a pipe body 1, an outer protective ring 2, an inner clamping ring 3, an inner sleeve 4, a first sealing ring 5, a second sealing ring 6, a connecting sleeve 7 and a positioning bolt 8, the outer wall of the end of the pipe body 1 is fixedly connected with the outer protective ring 2, and the inner clamping ring 3 is fixedly arranged on the inner wall of the end of the pipe body 1 on the side of the outer protective ring 2, the inner sleeve 4 is fixedly installed on the inner wall of the end of the pipe body 1 away from the outer protective ring 2, and the first sealing ring 5 is bonded to the surface of the inner sleeve 4, and the second sealing ring 6 is fixedly connected to the end face of the pipe body 1 on the side of the inner sleeve 4, the outer wall of the pipe body 1 is sleeved with a connecting sleeve 7, and the inner wall of the connecting sleeve 7 is movably connected with a positioning bolt 8.

[0022] The outer protective ring 2 and the connecting sleeve 7 are respectively fitted with the second sealing ring 6, and the outer protective ring 2 and the connecting sleeve 7 are threadedly connected, so that when adjacent pipelines are installed, the outer protective ring 2 on one side of the pipeline fits the second sealing ring 6 on the other side of the pipeline, thereby sealing the pipeline, and the user is convenient to rotate the connecting sleeve 7 so that the connecting sleeve 7 is inserted into the outer protective ring 2, thereby partially connecting the pipelines and allowing the connecting sleeve 7 to press the second sealing ring 6 to fit tightly against the outer protective ring 2.

[0023] The inner clamping ring 3 and the inner clamping sleeve 4 are slidably arranged, so that when the adjacent pipelines are installed, the inner clamping ring 3 is sleeved onto the outside of the inner clamping sleeve 4, thereby improving the stability of the pipeline connection.

[0024] The inner snap ring 3 and the first sealing ring 5 are arranged in close contact, so that the inner snap ring 3 can be in close contact with the first sealing ring 5, thereby performing a preliminary seal between adjacent pipes.

[0025] The connecting sleeve 7 and the pipe body 1 form a sliding structure, which facilitates the connecting sleeve 7 to move relative to the pipe body 1.

[0026] The positioning bolts 8 are respectively threadedly arranged with the connecting sleeve 7 and the pipe body 1, and the positioning bolts 8 are symmetrically distributed about the transverse center axis of the pipe body 1, so that the user can rotate the connecting sleeve 7 to insert the outer protective ring 2, and then rotate the positioning bolts 8 to insert the positioning bolts 8 into the pipe body 1, thereby achieving a stable connection between adjacent pipes.

[0027] Working principle: When using the reinforced concrete jacking pipe, first Figure 1-4As shown, the user connects the adjacent pipes through a tool. At this time, the pipe on one side drives the inner clamping ring 3 to be sleeved on the outside of the inner clamping sleeve 4 on the pipe on the other side. As the pipe continues to move, the inner clamping ring 3 moves along the inner clamping sleeve 4 and fits with the first sealing ring 5. At this time, the adjacent pipes squeeze the second sealing ring 6, and then the user rotates the connecting sleeve 7 so that the connecting sleeve 7 is inserted into the outer protective ring 2, and as the connecting sleeve 7 continues to rotate, the connecting sleeve 7 finally squeezes the second sealing ring 6 close to the outer protective ring 2, thereby completing the partial connection of the adjacent pipes. Next, when the connecting sleeve 7 is installed, the positioning bolt 8 on the connecting sleeve 7 is aligned with the screw hole set on the pipe body 1. At this time, the user rotates the positioning bolt 8 so that the positioning bolt 8 moves relative to the connecting sleeve 7 and is inserted into the pipe body 1, thereby limiting the connecting sleeve 7 and completing the installation of the adjacent pipes. At this time, the first sealing ring 5 and the second sealing ring 6 seal the adjacent pipes, thereby enhancing the sealing of the device and preventing pipeline leakage from affecting the normal use of the reinforced concrete jacking pipe.
