Operation Of Prestressed Anchorage In Positive And Negative Directions

Prestressed anchorages are divided into self-propelled prestressed anchorages and towed anchorages according to the walking form. According to the control system of the anchor bucket, it can be divided into two types: wire rope control and hydraulic control. The characteristics of pre-stressed anchors are easy and sensitive handling, rapid overturning progress, high consumption frequency and low actual operating costs. The flat site is being used in the construction of anchors, heavy foundation pits are excavated, reservoirs and roadbeds are filled, and the pre-stressed anchors need to be excavated after the capacity of the anchor machine is loosened. Because hydraulic transmission has great functionality, it stagnates quickly, and has basically replaced machine transmission.

 

Pre-stressed anchors, digging anchors, earth-moving, normal anchors, digging anchors, are normally only used to excavate anchors above the stop surface. The feature of digging anchors is that the machine moves and overturns, and the anchor bucket is forced to cut anchors from bottom to top. Pre-stressed anchors have large excavation force and high frequency, and are practically used for the same type of anchors whose water content is not greater than the standard. It can indirectly unload anchors on dump buses and stop the outbound task of pre-stressed anchors. The working forms of prestressed anchors mainly include side excavation and forward excavation. Lateral excavation is the digging of anchors along the traveling position of the digging anchor, and the anchor is installed on the front when the transporting machine stops. When this method is used for digging and unloading anchors, the swing position of the show arm is relatively small, the carrying and conveying machine is easy to overturn, the consumption rate is high, and the acceptance rate is wide. The excavation forms of anti-prestressed anchorage can be divided into two types: trench end excavation and trench side excavation. Ditch end excavation is the application of digging anchors at the end of the ditch, and the application of digging anchors is developing backward. The car is parked and anchored on both sides to realize trench excavation. This is the movement of the digging anchor along the side of the trench while walking. Just dig.
