[0039] 1. The traditional manual hand-held hammer is directly used to nail the rail jointing wire into the rail hole, and the construction time is basically equivalent to the construction time of the utility model, but the construction quality of the traditional method depends on the experience of the operator, and experienced technical personnel must be arranged for re-inspection, and 100km of line needs to be inspected for 100 / 2.5=40 hours at the inspection speed of 2.5km / h.

[0042] 1. The traditional artificial hand-held hand hammer directly into the rail hole rail joint line nail way: if the operating personnel improper operation, damage a rail, its material cost of about 40000 yuan, labor cost according to the general worker 200 yuan / day, 10 operating personnel, 200*10=2000 yuan, material transportation cost according to 1000 yuan, material hoisting cost according to 1000 yuan, replace a rail at least produces direct cost 40000+2000+1000+1000=44000 yuan.

[0043] 2. The construction of the present application will not produce rail damage, equivalent to save 44000 yuan.

[0044] The construction of the present application can also ensure the accuracy of the joint line plug nail, thereby ensuring the good electrical connection of the joint line and the rail, reducing the equipment failure hidden danger, and improving the stability of the railway signal transmission.
