Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a construction ground drilling and backfilling device. Background Art

[0002] During construction, holes are drilled into the ground as needed. After completion, the holes need to be backfilled. Currently, the conventional backfilling method involves workers pushing a cart loaded with concrete mortar to the backfill location. Once the mortar is shoveled into the drilled hole, it is filled completely. This conventional backfilling method is labor-intensive.

[0003] Patent application number 2018221954494 discloses a drilling and backfilling device for construction sites. The device comprises a housing and an arc-shaped partition disposed within the housing to divide the housing into upper and lower sections. The housing is provided with movable wheels at the bottom. A connecting pipe is provided on the lower surface of the arc-shaped partition, connecting to the upper section of the housing. A vertical filling conduit is slidably connected to the lower section of the housing. An inclined material guide pipe is connected to the side of the filling conduit, and the end of the inclined material guide pipe, facing away from the filling conduit, is sleeved onto the outer surface of the connecting pipe. A spiral blade is rotatably connected to the filling conduit. An extrusion motor is provided on the filling conduit to drive the spiral blade. An adjustment unit is provided within the housing to allow the filling conduit to move up and down, and is fixed. The extrusion motor drives the spiral blade to rotate within the filling conduit, causing the filling material in the filling conduit to move downward along the spiral blade into the borehole. The adjustment unit drives the filling conduit up and down within the borehole, compacting and refilling the borehole.

[0004] The aforementioned application compacts the filler material only through a filler pipe that can move up and down. The filler pipe can only contact the filler material through its pipe wall, resulting in an unsatisfactory compaction effect. Based on the above technical problems, the inventors have proposed a new construction ground drilling backfilling device that can significantly improve the compaction effect of the filler material.

The cylinder seat of the first cylinder 9 is fixed to the mounting plate 18, and the piston rod of the first cylinder 9 is connected to the sealing plate 7. When injecting material into the drilled hole, the sealing plate 7 descends to cover the hole first, and then concrete mortar is injected into the drilled hole through the mortar pump 14.
