[0032] like Figure 1 and Figure 2 As shown, the utility model provides a foldable passage device, including an assembled channel 1 and a guardrail 2. The assembled channel 1 includes at least two pedals 11 hinged along the length direction of the construction groove 100. Each pedal 11 is set on the guide walls on both sides of the construction groove 100. The pedal 11 has a tread 111, which is used for people to step on. The side of the pedal 11 opposite to the tread 111 is the bottom surface; two adjacent treads 111 or two adjacent bottom surfaces can approach each other under the action of external force so that the two adjacent pedals 11 are folded; the guardrail 2 is detachably arranged on the two pedals 11 at both ends of the assembled channel 1. In this embodiment, the assembly passage 1 includes at least two pedals 11. Since each pedal 11 is set on the guide walls on both sides of the construction groove 100, and the pedal 11 has a tread 111 for people to step on, the construction workers can pass through the construction groove 100 between the guide walls on both sides through the assembly passage 1, thereby greatly reducing safety hazards; since the two adjacent pedals 11 are hingedly connected, and the treads 111 or bottom surfaces of the two adjacent pedals 11 can be pressed against each other under the action of external force, so that the two adjacent pedals 11 are folded up, when the underground continuous wall construction is completed, the assembly passage 1 can be folded up. The assembled passage 1 is foldable, which greatly facilitates transportation and storage. At the same time, the corresponding number of pedals 11 can be unfolded according to the length of the construction trough 100 and the conditions of the passing machinery. Therefore, the foldable passage device is suitable for the passage of personnel and various types of machinery, and is also suitable for construction troughs 100 of different lengths. It has strong practicality and environmental adaptability. Since the two pedals 11 at both ends of the assembled passage 1 are equipped with guardrails 2, the guardrails 2 can protect personnel and prevent them from accidentally falling into the construction trough 100, thereby further improving the safety of the foldable passage device. Specifically, when using the foldable passage device, the construction worker stretches out the assembled passage 1 in the folded state so that the treads 111 of all pedals 11 are horizontally connected, and then installs the guardrails 2 on the two pedals 11 at both ends along the stretching direction. When the foldable passage device is finished using, the construction worker first removes the guardrails 2, and then uses tools to flip the pedals 11 to fold them, and finally folds them into an accordion fold structure, which is convenient for transportation and storage.

[0033] Furthermore, if Figure 1 and Figure 2As shown, the foldable passage device also includes a lifting plate 3, which is detachably mounted on the pedals 11 at the end of the assembly passage 1. The lifting plate 3 is provided with lifting holes for connection to a lifting device. In this embodiment, through holes are provided on the two pedals 11 at the end of the assembly passage 1. The lifting plate 3 is detachably connected to the two pedals 11 at the end via bolts. After the foldable passage device is used, the construction worker can use the lifting equipment to lift the entire assembly passage 1 via the lifting plate 3. Subsequently, the individual pedals 11 can be folded in the process of lowering the height of the assembly passage 1, thereby greatly saving manpower and improving work efficiency.

[0034] Furthermore, if Figure 1 and Figure 2 As shown, the pedal 11 is rotatably provided with rollers 4. In this embodiment, the pedal 11 is provided with rollers 4 at both ends perpendicular to the length of the construction trough 100, which facilitates construction workers to move the foldable passage device on the guide wall, thereby facilitating adjustment of the position of the foldable passage device, greatly improving construction convenience.

[0035] Specifically, the foldable passage device further includes a stopper that abuts against the roller 4 and is configured to limit the rotation of the roller 4. In this embodiment, a stopper is placed on both sides of the roller 4 in the rolling direction. The stopper is a wedge-shaped steel block, and the wedge-shaped inclined surface of the stopper abuts against the outer circumference of the roller 4, thereby effectively preventing the roller 4 from rolling. In another embodiment, the stopper is a U-shaped rod detachably mounted on the pedal 11. One side of the U-shaped rod is inserted or bolted to the pedal 11, and the other side of the U-shaped rod is axially inserted between the spokes of the roller 4.

[0036] Furthermore, the pedal 11 is made of a steel plate, and a reinforcing rib is provided on the bottom surface of the pedal 11. In this embodiment, the pedal 11 is made of a rectangular steel plate with a thickness of 5 mm, and the reinforcing rib is welded on the bottom surface of the pedal 11, which improves the structural strength and rigidity of the pedal 11, thereby ensuring the load-bearing capacity of the assembled channel 1.

[0037] Furthermore, the guardrail 2 is bolted to the pedal 11. In this embodiment, the guardrail 2 is bolted to the pedal 11 for easy assembly and disassembly.

[0038] Furthermore, if Figure 1 and Figure 2As shown, the assembly channel 1 also includes a hinge structure 12, which includes a first page body and a second page body. The first page body and the second page body are respectively fixed on two adjacent treads 111 or two adjacent bottom surfaces. The first page body and the second page body both have pin holes, and pin shafts are inserted into the pin holes; a first stop portion is provided on the first page body, and a second stop portion is provided on the second page body. The first stop portion and the second stop portion are configured to limit the rotation range of the first page body and the second page body so that the treads 111 of the two adjacent pedals 11 are unfolded to a horizontal position. In this embodiment, a common hinge structure 12 is provided between two adjacent pedals 11, and the first leaf body and the second leaf body are respectively installed on the two pedals 11, and the first leaf body and the second leaf body are rotated together by a pin shaft; since a first stop portion is provided on the first leaf body and a second stop portion is provided on the second leaf body, when the two adjacent pedals 11 are rotated to the tread 111 to be horizontally connected, the first stop portion and the second stop portion abut against each other. At this time, the two adjacent pedals 11 are in a fully expanded state, and the first leaf body and the second leaf body are limited by the first stop portion and the second stop portion and cannot continue to rotate, thereby ensuring the stability of the pedals 11 and preventing the adjacent pedals 11 from continuing to rotate and being unable to maintain a horizontal connection.

[0039] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
