This invention relates to the technical field of rotary drilling pile empty pile section construction, and discloses a construction method for solidifying the excavated soil in the empty pile section of rotary drilling piles to replace construction waste backfilling. The method includes the following steps: A pile hole is formed by rotary drilling at the construction site; the excavated soil is sequentially soaked and screened to form a screened slurry, which is then placed in a slurry pool; an empty pile section is formed at the top of the pile hole, containing empty pile slurry; the empty pile slurry in the upper part of the empty pile section is extracted and placed in the slurry pool, where it is mixed with the screened slurry to form a solidified slurry; the empty pile slurry in the lower part of the empty pile section forms a sedimented slurry; a solidifying agent is added to the slurry pool and stirred to form a solidified slurry; the solidified slurry is filled into the empty pile section, and the solidified slurry is stirred and mixed with the sedimented slurry to form solidified soil; after solidification, the solidified soil forms a solidified pile filling the empty pile section. In this way, the empty pile section is backfilled, achieving energy conservation, environmental protection, and cost and material savings through waste-to-resource conversion.

The utility model relates to short -distance self -discharging transportation technical field, proposes a kind of interlocking mechanism of control walking when hopper car unloading, including air compressor, the gas outlet of air compressor is fixedly penetrated with conveying pipe, the one end of conveying pipe away from the gas outlet of air compressor is fixedly connected with follow-up valve, the gas outlet of follow-up valve is fixedly penetrated with brake air pipe, the one end of brake air pipe away from the gas outlet of follow-up valve is fixedly connected with brake pump, the top of brake pump is provided with interlocking mechanism. In the utility model, the gas circuit and circuit connection between electromagnetic control check valve, travel switch, automatic reset normally closed switch are utilized, carriage and travel brake system are automatically interlocked, to realize the automatic control that self -discharging car carriage is in lifting state and cannot walk, through above technical scheme, solve the problem of the automatic control that self -discharging car carriage is in lifting state and cannot walk in prior art.

The present application relates to the technical field of cast-in-place pile construction, and discloses a stirring structure for curing slurry muck of a cast-in-place pile empty pile section, which comprises a excavator with a removed excavating bucket, the excavator comprising a movable body and a swing arm, a power head being hingedly connected to the swing arm, a stirring drill rod being connected to the power head, and a stirring drill bit being arranged at the bottom of the stirring drill rod; a hollow cylinder is movably arranged on the outer periphery of the lower section, and the hollow cylinder is movably connected to the lower section; the power head drives the stirring drill rod and the stirring drill bit to synchronously rotate, slurry is sprayed out of a slurry outlet, high-pressure gas is sprayed out of a gas outlet, the drill rod blades and the drill bit blades synchronously stir the slurry muck and the curing slurry, and the hollow cylinder is in a free state and is pressed and rotated by the slurry muck. The slurry muck is rapidly cured by stirring the curing slurry and the slurry muck and spraying the high-pressure gas, and the strength of the original soil can be reached in a short time, thereby ensuring the normal walking of the mechanical equipment in the construction site.

The application provides a self-propelled mower and a self-propelled control method of the self-propelled mower. The self-propelled mower comprises a machine body, a walking wheel assembly and a control assembly. The walking wheel assembly comprises a first walking wheel, a second walking wheel, a first wheel hub motor and a second wheel hub motor. The first wheel hub motor is used for controlling the rotating speed of the first walking wheel, and the second wheel hub motor is used for controlling the rotating speed of the second walking wheel. The control assembly comprises a first wheel hub controller and a second wheel hub controller. The first wheel hub controller is configured to send a control instruction to the first wheel hub motor and the second wheel hub controller, so that the first wheel hub motor controls the first walking wheel to walk at a speed setting value in the control instruction. The second wheel hub controller is configured to receive the control instruction sent by the first wheel hub controller and transmit the control instruction to the second wheel hub motor, so that the second wheel hub motor controls the second walking wheel to also walk at the speed setting value in the control instruction, thereby enabling the self-propelled mower to walk in a straight line.

The utility model discloses a raw material silo conical hopper cleaning robot, and relates to the field of cleaning robots. The raw material silo conical hopper cleaning robot comprises a cleaning robot body and a cable connected with the cleaning robot body, the cleaning robot body walks on the inner wall of the raw material silo conical hopper and conducts cleaning through the cable, the cable is connected with a positioning unit, and the positioning unit is installed at the top of the raw material silo conical hopper. And the positioning unit can walk along a top silo opening of the raw material silo conical hopper. According to the raw material silo cone hopper cleaning robot, through the synergistic effect of linear bearings and walking wheels of the positioning units, physical isolation of a cable and the edge of a silo opening is achieved, cable winding and abrasion are avoided, an L-shaped fixed strip and an L-shaped movable strip of the positioning units are installed across the silo opening, the two walking wheels are combined to be attached to the top of a silo, and the cleaning efficiency is improved. And ensuring that the robot walks along the preset path.
