After the construction of the pipe ditch working surface of the first construction section is completed, the length of the guard rail member 13 in the fully extended state is calculated according to the length of the pipe ditch excavation working surface of the first construction section, and the new first support member 10 and the new second support member 11 are arranged and fixed on the base surface according to the length of the guard rail member 13 in the fully extended state. A rope 12 on a drum 104 of the first support member 10 is passed through a wire guide wheel 106, a first wire guide tube 107, a first support pulley 103 positioned above and fed to a second support pulley 113 positioned above of the second support member 11 to be bound to a rope locking ring 114, and then a handle 105 on the drum 104 is fixed to the first base 100. The other rope 12 on the other drum 104 in the first supporting member 10 is passed through the other wire guiding wheel 106, the first supporting pulley 103 positioned below and conveyed to the second supporting pulley 113 positioned below in the second supporting member 11 and then is bound on the other rope locking ring 114, and then the rotating handle 105 on the drum 104 is fixed with the first base 100.

Step four,

The guard rail member 13 is divided into segments of equal length according to the length of the guard rail member 13 in the fully extended state. The connection point of each section is a demarcation point.

The middle support member 16 of the first construction section furthest from the second construction section is removed and positioned and secured at the second construction section at the point of demarcation closest to the first construction section, and such that the two U-shaped support rails in the middle support member 16 support the two ropes 12, respectively. The guard rail members 13 on the two ropes 12 of the first construction site are then moved to the two ropes 12 of the second construction site by the wire passing rods 116 in the second support member 11 of the first construction site after being disconnected from the first support member 10 and the second support member 11 of the first construction site. The above steps are repeated until the first construction section has no intermediate support member 16 or the guard rail member 13 of the second construction section reaches a calculated length. If the first construction section does not have a central support member 16, but the guard rail member 13 of the second construction section does not reach the calculated length, then one central support member 16 is positioned and secured at each remaining demarcation point, and the two U-shaped support rails in each central support member 16 are made to support two ropes 12, respectively. The components are assembled into a length of rail guard member 13, and then the pulleys 131 in the length of rail guard member 13 are supported on the two ropes 12 of the second construction section. The section of rail guard element 13 is then connected to the last section of rail guard and the above steps are repeated until the rail guard element 13 of the second construction section reaches the calculated length. Next, the guard rail member 13 is connected to the first support member 10 and the second support member 11 to obtain the safety device 1 of the second construction section, and the trench working surface construction of the second construction section is performed.

If the guard rail member 13 of the second construction section reaches the calculated length, said first construction section also has a middle support member 16, the middle support member 16 of the first construction section is subsequently removed together with the first support member 10 and the second support member 11 for the third construction section.

In addition, the above-described manner of removing the intermediate support member 16 of the first construction section and the manner of installing the intermediate support member 16 of the second construction section are: the middle support members 16 of the first construction section are removed one by one in the order from the second construction section to the next to the second construction section, and the removed middle construction members are mounted one by one to the second construction section in the order from the next to the first construction section to the next to the first construction section. Wherein the middle support members 16 of the first construction site may also be removed by removing the middle support members 16 of every other first construction site in a direction from the second construction site to the next second construction site.
