[0002] With the rapid development of the national economy, economically developed coastal cities are growing in size and increasing in number of buildings. Earthwork backfilling is a common construction process to ensure that structural loads can be transferred to the ground. However, due to the limitations of existing backfill technology, the backfill density often falls short of expectations. Furthermore, due to factors such as earthwork settlement, gaps or large unfilled spaces may exist between the structural slab and the backfill soil, necessitating a secondary backfill at a later stage.

A vertical gear 94 for controlling the movement of the vertical rod 91 is provided on the mobile pumping machine 5. A horizontal gear 95 for controlling the movement of the horizontal rod 92 is provided at the lower end of the vertical rod 91. The horizontal rod 92 and the rotating rod 93 are hinged by setting a hinge 96. The vertical gear 94 is controlled by the mobile pumping machine 5 to operate, which is convenient for controlling the vertical up and down movement of the vertical rod 91, and the horizontal gear 95 is controlled by the mobile pumping machine 5 to operate, which is convenient for controlling the horizontal rod 92 to move horizontally, and the angle of the rotating rod 93 can be adjusted through the hinge 96.

[0031] A winder 97 is provided on the horizontal rod 92, and a connecting wire 98 is wound on the winder 97. A fixed end 99 is fixedly provided on the rotating rod 93. The end of the connecting wire 98 away from the winder 97 is fixedly connected to the fixed end 99. By controlling the operation of the winder 97, the connecting wire 98 can be wound. At this time, the connecting wire 98 pulls the fixed end 99 and the rotating rod 93 to deflect, thereby facilitating the adjustment of the angle of the rotating rod 93.

[0032] A paint nozzle 10, a pinhole camera 11, a mortar nozzle 12 and a laser ranging head 13 are arranged in the adjustable pouring part 9. The control ends of the paint nozzle 10, the pinhole camera 11, the mortar nozzle 12 and the laser ranging head 13 are connected to the mobile pumping machine 5. The rotating rod 93, the horizontal rod 92 and the vertical rod 91 are all hollow rods. An opening 910 is provided at the end of the rotating rod 93 away from the horizontal rod 92. One end of the paint nozzle 10, the pinhole camera 11, the mortar nozzle 12 and the laser ranging head 13 is arranged in the opening 910 of the rotating rod 93, and the other ends of the paint nozzle 10, the pinhole camera 11, the mortar nozzle 12 and the laser ranging head 13 pass through the rotating rod 93, the horizontal rod 92 and the vertical rod 91 in turn and are connected to the mobile pumping machine 5.

[0033] By setting it as a hollow rod, the paint nozzle 10, the pinhole camera 11, the mortar nozzle 12 and the laser ranging head 13 can be connected to the mobile pumping machine 5 through the rotating rod 93, the horizontal rod 92 and the vertical rod 91, and then the paint nozzle 10, the pinhole camera 11, the mortar nozzle 12 and the laser ranging head 13 can be controlled by cooperating with the control display 8 and the mobile pumping machine 5, and the opening 910 of the rotating rod 93 can reach the innermost end of the gap 3 by adjusting the angle of the rotating rod 93.

[0034] Retaining piles 14 are provided around the gap 3 of the soil body 1, and the filling position is conveniently enclosed and protected by the retaining piles 14.

[0035] Working principle: When using the gap filling device under the soft soil structural plate, first determine the range of the gap 3, place the guide rail base 4 on it, and then fix it to the structural plate body 2 with the connecting piece 41;

[0036] Then connect the roller 51 of the mobile pumping machine 5 to the guide rail base 4, and then connect the mobile pumping machine 5, paint bucket 6, mortar bucket 7 and control display 8 and other device components in sequence and debug;

[0037] The vertical rod 91 is controlled to move up and down by the control display 8, so that the horizontal rod 92 is at the same level as the gap 3, and the horizontal rod 92 is controlled to move into the gap 3. During the movement, the height of the horizontal rod 92 and the angle of the rotating rod 93 are adjusted in time by the pinhole camera 11 until the opening 910 reaches the innermost end of the gap 3;

[0038] Since the soil 1 in the gap fluctuates, in order to ensure the spraying effect, the angle of the rotating rod 93 is controlled by the reel to control the angle of the opening 910, so as to achieve spraying at different angles;

[0039] The mortar nozzle 12 is controlled by the control display 8 to spray the prepared mortar in the mortar bucket 7 at a uniform speed. Due to the fluidity of the mortar, the gap is gradually filled from bottom to top. During the filling process, the filling status is checked at any time through the pinhole camera 11. The distance is measured by the laser rangefinder 13 to control the distance between the opening 910 and the target. When the filling is close to the bottom of the structural plate body 2, the spraying is stopped.

[0040] The paint nozzle 10 is controlled by the control display 8 to spray the prepared paint in the paint bucket 6 at a uniform speed, and the horizontal rod 92 is moved back from the gap while spraying. The roller 51 is controlled by the control display 8 to move on the guide rail base 4. When it moves to the next gap 3 area, the above steps are repeated to spray and fill the gap; finally, the device is disassembled and cleaned.
