technical field

The utility model relates to a bearing device, in particular to a portable arched pier bearing device.

Background technique

For deep foundation pit projects with rich groundwater content, it is often necessary to take foundation pit dewatering measures to ensure the dryness of the excavation surface and the safe and smooth progress of the later construction. The more common foundation pit dewatering methods in practical engineering are the open-draining method and the well-pipe method. The open-drainage method refers to the direct discharge of surface water through the interception and drainage ditch, while the well-pipe method refers to setting up several pumping wells in the foundation pit and using the pumping wells. The wells pump water continuously to reduce the groundwater level in the foundation pit to the design water level that does not affect the normal construction. However, because precipitation is a continuous process, the amount of water pumped is often large over time, and the smooth drainage directly affects the construction period. out of the foundation pit.

When dewatering the foundation pit, the overlapping drainage pipes will be laid on the transportation road around the foundation pit, and long-term water pumping is often required to ensure the stable dewatering effect of the foundation pit. Cranes, excavators, etc. pass normally. The long-distance drainage pipe belt occupies a lot of ground space. If it is directly rolled and heavy, it can only be slow to pass after the pumping is completed. The existing drainage pipes are divided into rigid and flexible, that is, steel wire branch pipes and fire hoses with rubber lining and flax braided outside, both of which need to be sealed and overlapped with each other in series to prevent water leakage at the interface; And neither of them can bear a large load, and direct rolling will cause the drainage pipe belt to rupture.
