Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0045] The technical solution of the utility model is used to solve the problems in the prior art that the upper wall surface of the pipe opening of the jacking pipe construction protection device is prone to falling or collapse during the manual excavation process, and the device is not stable enough.

[0046] Reference Figure 1 A pipe jacking construction protection device comprises: a fixed frame 100 and a protection device 200 arranged on the fixed frame 100; the fixed frame 100 has two support units 110, and a mounting platform 120 is arranged above the support unit 110; the protection device 200 comprises a driving member 210, a support assembly 220, and a protective cover 240; the protection device 200 is fixedly connected to the mounting platform 120 through the driving member 210, the output end of the driving member 210 is transmission-connected to the support assembly 220, and the protective cover 240 abuts against the support assembly 220; the driving member 210 can drive the support assembly 220 to move toward the upper wall surface of the pipe nozzle, and support the protective cover 240 to abut against the upper wall surface of the pipe nozzle to prevent the gravel on the upper wall surface of the pipe nozzle from falling. It is understandable that the driving member 210 can provide driving force so that the support assembly 220 can push the protective cover 240 toward the upper wall of the pipe mouth, and the support assembly 220 acts on the upper wall of the pipe mouth through the protective cover 240 to support it, and at the same time, the protective cover 240 can block the gravel falling from the outer periphery of the inner wall of the pipe mouth, providing a safe working environment for the staff. In addition, since the protective cover 240 is in contact with the support assembly 220, that is, the protective cover 240 and the support assembly 220 have dynamic adjustment capabilities, which can significantly improve the construction safety, device stability and construction efficiency.

[0047] A pipe jacking construction protection device of the utility model is located at the front end of the pipe jacking construction, and is used to support the top wall in front of the pipe jacking. When in use, the driving member 210 drives the support assembly 220 to move toward the top wall and pushes the protective cover 240 against the top wall. At this time, the operator can work in the area below the protective cover 240. When the work in this area is completed, it is necessary to move the pipe jacking construction protection device to the next construction position for operation. At this time, the driving member 210 can contact the support through the support assembly 220, so that the pipe jacking construction protection device can be pushed into the next construction area more easily. At this time, the protective cover 240 and the support assembly 220 are in abutment, that is, a split connection method. When the top wall has extremely complex working conditions, the split connection can facilitate the movement of the pipe jacking construction protection device, which can improve the flexibility of the device.

[0048] Furthermore, in order to further improve the flexibility of the protective device, refer to Figure 1 , a sliding member 1111 is provided at one end of the base 111 away from the support column 112.

By providing the sliding member 1111, not only time and labor are saved, but also construction efficiency and flexibility are improved. In addition, the sliding member 1111 can also be adjusted according to different construction requirements to adapt to different construction environments and ground conditions to ensure the stability and safety of the protective device. More specifically, the sliding member 1111 can be a roller, a universal wheel, a pulley, etc.

[0049] Furthermore, two L-shaped plates are provided between the two bases 111, and the two L-shaped plates are respectively connected to the two bases 111 by bolts. The L-shaped plates are used to shield the debris entering the construction area.

[0051] In some embodiments, reference Figure 1 , 4The support unit 110 includes a base 111 and a support column 112 disposed on the base 111; the support unit 110 is fixedly connected to the mounting platform 120 through the support column 112; a stopper 113 is disposed on the support rod at one end facing the pipe mouth, one end of the stopper 113 is fixedly connected to the support rod and the other end is in contact with the ground. When in use, since the protective device needs to be kept fixed, the stopper 113 is provided to prevent the protective device from moving backwards. With the support of the stopper device, the construction safety and the stability of the device are improved.

[0052] Further, refer to Figure 4 The stopper 113 includes a stopper rod 1131, a clamp ring 1132 connected to the support column 112 at one end of the stopper rod 1131, and a stopper seat 1133 abutting against the ground at the other end; the stopper 113 is detachably connected to the support column 112 through the clamp ring 1132. The detachable connection between the stopper 113 and the support column 112 through the clamp ring 1132 improves the convenience of installation and removal of the stopper 113, enhances the adaptability of the device to different construction environments, and ensures stability and flexibility in variable terrains. Among them, one end of the stopper 113 is fixed to the support column 112 through the clamp ring 1132 by fastening bolts, and the other end is pressed against the ground through the stopper seat 1133, so that the protection device 200 is supported while the stability of the entire device is improved.

[0053] Further, continue to refer to Figure 4 The bottom of the stopper 1133 is provided with a plurality of cone thorns 1133a on the side facing the ground, and the plurality of cone thorns 1133a are distributed in a rectangular array.
