The present invention relates to the technical field of friction cast-in-place piles in karst areas, and in particular to a boundary body segmental preloading construction method for friction-type cast-in-place piles in karst areas. A boundary body for covering karst caves is arranged in pile foundation holes in karst areas. A segmented preloading device is set in the boundary body, and the boundary body is pressurized in sections from bottom to top through the segmented preloading device. Specifically, the boundary body is first separated into mutually independent Connected upper and lower areas, then pressurize the lower area and then grout into the lower area, switch the lower area and upper area into a connected state, and repeat the above steps in sequence until the pouring of the entire pile is completed. The advantages of the present invention are: simple operation, first divide the boundary body into upper and lower regions that are not connected to each other, then pressurize the lower region and then grout the lower region, so that the boundary body can be effectively controlled Extensibility in different caves.

A substation system high-tension line maintenance gear transmission lifting type operating device comprises a walking support, a gear transmission mechanism and a lifting mechanism. The lifting mechanism is located in front of the support. The gear transmission mechanism is located at the lower middle position of the support. The gear transmission mechanism drives the lifting mechanism. The lifting mechanism conducts high-tension line grounding work during the lifting movement along a preset rail. The gear transmission mechanism can achieve a self-locking function so that a grounding wire rope can stay at a certain height and the high-tension line grounding work can be convenient. A mechanical lifting telescopic rod mode replaces a current mode that grounding is operated manually by workers during substation system high-temsion line maintenance work, electric shock accidents can be effectively avoided, and guarantees are provided for life safety of maintainers.

The invention relates to a stainless steel honeycomb inclined-tube wave plate forming method for a water treatment sedimentation tank and a forming device.
