Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology, specifically to a cable protection structure suitable for pipe jacking construction. Background Technology

[0002] In the field of urban underground pipeline construction, pipe jacking is widely used due to its minimal impact on surface traffic. However, during pipe jacking, various longitudinally arranged cables, such as communication cables and power cables, often exist around the construction area. These cables are usually laid parallel to the construction path, and the continuous advancement of the pipe jacking machinery can easily cause displacement and disturbance of the surrounding soil. The outer wall of the pipe and the surface of the cable may rub against each other due to relative movement, which may cause damage to the outer insulation layer of the cable or even breakage of the internal conductor, posing a serious threat to the safe operation of municipal infrastructure. Although existing construction methods include pre-embedded warning boards and the installation of temporary isolation supports, there is a lack of effective means to prevent the contact risk between the pipe jacking and the cable during dynamic advancement.

[0003] Currently, most technical solutions for cable protection during pipe jacking construction focus on post-construction monitoring and remediation, such as using sensors to detect cable deformation or abnormal current. However, they struggle to proactively mitigate the risk of scraping during construction. For longitudinally arranged cables, their long-distance distribution along the pipe jacking axis makes it impossible for traditional point-based protection devices to form a continuous and effective protective barrier. When the pipe jacking shifts due to changes in geological conditions, existing protection structures are more prone to blind spots, leading to cable damage from direct friction against the outer wall of the pipe jacking. Utility Model Content

[0004] The purpose of this utility model is to provide a cable protection structure suitable for pipe jacking construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable protection structure suitable for pipe jacking construction, which is used to protect cables, comprising:

[0006] First protective shell;

[0007] The second protective shell is fastened to the first protective shell;

[0008] Shock-absorbing plates are disposed in the first protective shell and the second protective shell;

[0009] The inner shell, which is located on the shock-absorbing plate, wraps around the cable.

[0010] Preferably, the first protective shell is provided with a connecting groove, a rotating wheel is connected to the connecting groove, and a strap for binding the first protective shell and the second protective shell is wound around the rotating wheel.

[0011] Preferably, the second protective shell is provided with a connecting block, which is used to connect one end of the strap.

[0012] Preferably, both the first protective shell and the second protective shell have limiting grooves.

[0013] Preferably, there are at least two inner shells, each of which is provided with a plug-in slot and a magnetic attraction element.

[0014] Preferably, the dimensions of the insertion slot and the magnetic attractor are matched, and the magnetic attractor is also built into the bottom of the insertion slot.

[0015] Preferably, the shock-absorbing plates are distributed in a fan shape in the first protective shell and the second protective shell.

[0016] Preferably, the first protective shell and the second protective shell are respectively provided with a plug and a slot, and the outer dimensions of the slot and the inner dimensions of the plug are matched.

[0017] Preferably, the limiting groove is further provided with a support plate, which is used to change the position of the strap.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: This cable protection structure, applicable to pipe jacking construction, can form a three-dimensional protective barrier for longitudinally arranged cables, effectively avoiding the risk of scraping caused by direct contact between the outer wall and the cables during pipe jacking. The snap-fit ​​first and second protective shells, together with the shock-absorbing plate structure, can absorb the soil vibration and displacement stress generated during pipe jacking construction, significantly reducing the continuous impact of mechanical vibration on the cables, and fundamentally reducing the risk of insulation layer damage and conductor breakage.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a cable protection structure suitable for pipe jacking construction, which is used to protect cables, comprising:

[0026] The first protective shell 1 and the second protective shell 2 are fastened together to complete the assembly of the device. The dimensions of the first protective shell 1 and the second protective shell 2 are matched. The first protective shell 1 is provided with a connecting groove 11, which is used to support the rotating wheel 12. The rotating wheel 12 is connected to the connecting groove 11 and is used to lock the strap 9 to ensure the stability of the connection between the first protective shell 1 and the second protective shell 2. The strap 9 is wrapped around the rotating wheel 12 for binding the first protective shell 1 and the second protective shell 2. The strap 9 is used to fit into the limiting groove 10 to make a stable connection between the first protective shell 1 and the second protective shell 2.

[0027] The second protective shell 2 is fastened to the first protective shell 1. The second protective shell 2 is provided with a connecting block 21, which is used to connect one end of the strap 9 to prevent the strap 9 from being lost. Both the first protective shell 1 and the second protective shell 2 are provided with limiting grooves 10, which are used to limit the strap 9 to prevent it from falling off when it becomes loose, thus losing its binding and fixing effect on the first protective shell 1 and the second protective shell 2. The limiting groove 10 is also provided with a support plate 13, which is used to change the position of the strap 9 so that it can be wrapped around the rotating wheel 12. The support plate 13 is used to change the position of the strap 9. The first protective shell 1 and the second protective shell 2 are also provided with a plug 5 and a slot 6, respectively. When the plug 5 is inserted into the slot 6, the connection between the first protective shell 1 and the second protective shell 2 is further limited to prevent misalignment when the first protective shell 1 and the second protective shell 2 are connected. The outer dimensions of the slot 6 and the inner dimensions of the plug 5 are matched.

[0028] The shock-absorbing plates 3 are all installed in the first protective shell 1 and the second protective shell 2. The shock-absorbing plates 3 are distributed in a fan shape in the first protective shell 1 and the second protective shell 2, thereby absorbing the vibration of the inner shell 4. In case of accidents during construction, they can have a buffering effect. The internal cables will not move with the movement of the first protective shell 1 and the second protective shell 2, which would cause the cables to move with the rigid connection of the first protective shell 1 and the second protective shell 2, resulting in cable damage.

[0029] The inner shell 4 is located on the shock-absorbing plate 3 and wraps the cable. There are at least two inner shells 4. When in use, the inner shells 4 need to be spliced ​​together, just like the first protective shell 1 and the second protective shell 2. Each inner shell 4 is provided with a plug-in slot 7 and a magnetic 8. The plug-in slot 7 and the magnetic 8 are matched in size, and the bottom of the plug-in slot 7 also has a built-in magnetic 8. When the magnetic 8 on one inner shell 4 is inserted into the plug-in slot 7 of another inner shell 4, the connection between the two inner shells 4 is completed.

[0030] When using cable protection structures in pipe jacking construction, it is necessary to survey the approximate location of the cable, determine the construction location of the pipe jacking, identify the cables that may be affected, and then excavate the cable. Next, arrange the first protective shell 1 and the second protective shell 2 around the cable. Precisely align the magnetic 8 on the inner shell 4 with the insertion slot 7 to ensure a tight fit, completing the splicing of the inner shells 4 to completely enclose the cable. Fasten the first protective shell 1 and the second protective shell 2, inserting and fixing the plug 5 and slot 6 to initially assemble the protection structure. Finally, wrap the binding strap 9 around the first protective shell 1 and the second protective shell 2 and tighten it using the rotating wheel 12 to ensure a tight fit and achieve stable protection for the cable.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
