Problems solved by technology

[0002] The ballastless track structure of high-speed railways, general-speed railways or subways has high requirements on the smoothness of the track. However, in the actual process, the track is prone to settlement and offset problems. The common method is to restore the track line by adjusting the fasteners. However, once the settlement exceeds the adjustment capacity of the fastener, other methods must be used to restore the elevation and plane position of the track. After the elevation and plane position of the track are improved by the settlement lifting device, it needs to be filled The holes are filled with mortar to meet the support requirements after the rail subsides and rises. However, the existing technology is to directly use the mortar pipe to pour the mortar into the pouring hole. Using this method for pouring tends to cause the mortar to accumulate and make the corners The accumulation of mortar is limited and the density is not enough, which will affect the overall quality of the rails and cause safety accidents

Abstract

The present invention relates to the technical field of local subsidence and uplift of rail surface of high-speed railway, more specifically, a construction method of local subsidence and uplift system of rail surface of high-speed railway. Pull out two positioning pins, turn and adjust the transmission mechanism and make the holes correspond to the positioning holes, and insert the positioning pins into the two. At this time, the lower tube slides out of the base and enters the filling hole. The upward movement of the connected slide bar makes the upper regulating pipe slide down along the upper pipe, and the discharge port and the corresponding discharge semicircle hole form a complete outlet. After connecting the mortar output pipe, the mortar can be poured. From the above complete outlet The output mortar is sprayed around and injected evenly to avoid accumulation during mortar pouring, and there will be no shortage of mortar at the corners.
