Description

Technical Field

[0001] The invention relates to the technical field of roadbed filling, in particular to a roadbed filling construction device and a construction method thereof. Background Art

[0002] Roadbed filling is the process of filling the soil required for the roadbed with earth and stone and other materials during road construction to ensure the stability and bearing capacity of the road. When carrying out earth filling projects in areas with high groundwater levels, special attention should be paid to the impact of hydrological conditions on the quality and long-term stability of the fill. A high groundwater level will have a significant impact on the compactness, bearing capacity and settlement of the soil. Therefore, some special construction methods and technical means are needed in earth filling construction in such areas.

[0003] Areas with high groundwater levels usually undergo drainage to lower the groundwater level at the construction site and reduce the impact of moisture on the quality of the fill. After the moisture is drained, the soil settles and gradually forms a roadbed trench. Filling materials are laid in the roadbed trench for compaction. However, there are many troubles and inconveniences in the process of laying filling materials: areas with high groundwater levels often have complex terrain, relatively soft soil, and there are height differences in the roadbed trench. When unloading materials through the bucket of a fill transport truck, the fill transport truck needs to be moved multiple times to pour the filling materials to different locations in the roadbed trench, which is rather troublesome. In the process of unloading materials through the bucket, some of the filling materials are prone to dumping outside the roadbed trench, resulting in waste of filling materials.

A drainage mechanism 2 and a grouting mechanism 3 are arranged in the roadbed groove 1. The drainage mechanism 2 is used to drain the roadbed, and the grouting mechanism 3 is used to grout and reinforce the roadbed. Filling material 4 is arranged in the roadbed groove 1, and the roller 5 is used to compact the filling material 4. The filling material 4 is composed of a crushed stone layer 41, a gravel mixed soil layer 42 and an asphalt concrete layer 43 from bottom to top. The crushed stone layer 41 is used to support the filling material 4 above and buffer the dynamic load brought by the driving of vehicles on the road. The gravel mixed soil layer 42 has good compaction, stability and water permeability. The asphalt concrete layer 43 can prevent a large amount of rainwater from dripping in and keep the filling material 4 dry. A roller 5 is arranged in the roadbed groove 1. A box 6 is fixedly connected to the side wall of the roller 5. The box 6 is used for temporary storage and unloading of the filling material 4.

[0031] Specifically, the partition 7 can prevent the filling material 4 from being thrown forward, and the rotation of the lead screw 11 drives the active wheel 2 151 and the driven wheel 2 153 to rotate, thereby driving the driven shaft 2 152 and the bevel gear 1 155 to rotate, and the rotation of the bevel gear 155 drives the bevel gear 2 157 to rotate, thereby driving the driven shaft 3 156 and the dispersion blade 158 to rotate, and the filling material 4 descends and contacts with the protective component 18 on the top of the rotating dispersion blade 158, and the filling material 4 falls onto the rubber plate 184, which can make the filling material 4 rebound or throw the filling material 4 to the surroundings, increase the feeding range of the filling material 4, play a role in dispersing the feeding, and make the filling material 4 fill the inside of the roadbed groove 1, and the spring between the mounting rod 182 and the fixing tube 181 can buffer the impact of the falling of the filling material 4, and the rubber plate 184 has the advantages of good wear resistance and elasticity, which is conducive to rebounding the filling material 4 and dispersing the feeding.

[0033] Specifically, the pushing plate 84 can push and level the filling material 4 in the roadbed trench 1 as the road roller 5 moves, so that the filling material 4 can be laid evenly and the compaction degree of the filling material 4 can be improved.

[0034] A construction method according to the above roadbed filling construction device comprises the following steps: S1: dig several precipitation wells in the construction area, set up several water pumps in the construction area, install a pumping pipe at the input end of the water pump, install the pumping pipe into the precipitation well, install a drainage pipe at the output end of the water pump, dig a drainage ditch away from the construction area, lay the drainage pipe into the drainage ditch, the water level at the bottom of the construction area drops, the soil layer sinks and forms a roadbed groove 1; S2: Drill several vertical shafts on both sides of the roadbed trench 1 by means of a drilling rig, place a steel cage into the vertical shaft, and then pour concrete into the steel cage to form a pile body; S3: The roller 5 is hoisted into the roadbed trench 1 by a crane. The roller 5 first compacts the roadbed trench 1, and then delivers a plurality of filling materials 4 to the box 6 in sequence. The loading sequence is crushed stone layer 41 - gravel mixed soil layer 42 - asphalt concrete layer 43. The roller 5 unloads and compacts the plurality of filling materials 4, and adopts layered compaction. The thickness of the filling material 4 is controlled between 30 and 40 cm each time.

[0035] How it works The packaging bags containing the crushed stone layer 41 are transported to both sides of the roadbed trench 1 by manpower or a small cart, and the filling material 4 inside is poured into the temporary storage bin 10. At this time, the movable plate 12 blocks the temporary storage bin 10, and the roller 5 is located at one end of the roadbed trench 1; When it is necessary to unload materials, the roller 5 is moved to the other end, and the driving motor 9 drives the screw 11 to rotate. Since the screw 11 is a reciprocating screw, the movable plate 12 on the screw 11 will reciprocate. The movement of the movable plate 12 can make the filling material 4 in the temporary storage bin 10 leak out. At this time, the rotation of the screw 11 drives the driving wheel 131 to rotate, and the driven wheel 132 is rotated through the belt transmission, thereby driving the driven shaft 133 to rotate, and finally driving the stirring rod 134 to rotate. The rotation of the stirring rod 134 can stir the filling material 4 in the temporary storage bin 10 to avoid its blockage, thereby facilitating the unloading of the filling material 4, and the filling The filling material 4 then leaks into the lower feeding bin 14. At this time, the rotation of the lead screw 11 also drives the second driving wheel 151 and the second driven wheel 153 to rotate, thereby driving the second driven shaft 152 and the first bevel gear 155 to rotate. The rotation of the first bevel gear 155 drives the second bevel gear 157 to rotate, thereby driving the third driven shaft 156 and the dispersion blade 158 to rotate. The filling material 4 falls and contacts the rubber plate 184 on the top of the rotating dispersion blade 158, which can make the filling material 4 rebound or throw the filling material 4 to the surroundings, thereby increasing the feeding range of the filling material 4 and playing the role of dispersing the feeding, so that the filling material 4 fills the inside of the roadbed groove 1. After the roller 5 moves to the other end, the pushing plate 84 can push the filling material 4 in the roadbed trench 1 flat as the roller 5 moves, so that the filling material 4 can be laid evenly and the compaction degree of the filling material 4 can be improved. The gravel layer 41 has also been laid, and local adjustments can be made manually to make the gravel layer 41 laid perfectly. Then the roller 5 is moved in the opposite direction for compaction. The laying and compaction principles of the gravel mixed soil layer 42 and the asphalt concrete layer 43 are the same, and multiple layered compaction is adopted. The thickness of the filling material 4 is controlled between 30 and 40 cm each time. After each layer of the filling material 4 is filled, it is fully compacted to ensure the stability of the soil layer and avoid settlement or displacement due to the buoyancy of groundwater.

[0036] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
