[0003] During the construction of the central median, the filling work on the central median is often carried out after the asphalt pavement construction on both sides is completed. In the traditional earth shoulder filling and central median filling construction, a dump truck full of soil is used to transport the filling soil to the construction site, and then the dump truck is reversed horizontally on the asphalt pavement. After it is in place, the soil is poured out from the rear of the car. This traditional dump truck has a low degree of intelligence and is easy to deviate from the central median during operation, which affects the safety of the operation, reduces the efficiency of the construction, and increases the workload of the staff. For this reason, Chinese patent CN220598551U discloses a central median filling method.

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] See also Figure 1-3 , a mid-dividing belt filling construction equipment, comprising a transport vehicle 1, the transport vehicle 1 comprising a hopper 2, the hopper 2 is used to transport soil in batches to one side of the transport vehicle 1;

[0026] Specifically, in this embodiment, the hopper 2 is a quadrangular prism-shaped hollow structure placed on the transport vehicle 1 and transported by the transport vehicle 1. Soil is stored in the hopper 2. A discharge port 21 is provided on one of the side walls of the quadrangular prism-shaped hopper 2. The position of the discharge port 21 ensures that the soil in the hopper 2 can fall into the side or rear of the transport vehicle 1 after leaving the hopper 2 from the discharge port 21. At the same time, a push shovel 22 is provided in the hopper 2. The push shovel 22 is arranged toward the discharge port 21. The push shovel 22 is a structure that can be extended toward the discharge port 21, and is used to push the soil from the hopper 2 to the discharge port 21 during the extension and retraction process, thereby completing the transportation of the soil to the belts in the fill soil.

[0027] After the soil of the middle belt is transported, the workers carry out the filling construction. In this embodiment, the construction is divided into multiple layers of filling. At the beginning of the construction, the conveyor pulls the hopper 2 to move along the middle belt to transport soil to various places of the middle belt. After the first layer of soil of the middle belt filling is transported, the workers use a tamping machine to compact the first layer of filling. Subsequently, the conveyor pulls the hopper 2 to move along the middle belt to transport soil to various places of the middle belt. After the second layer of soil of the middle belt filling is transported, the workers use a tamping machine to compact the second layer of filling, and so on, until the filling construction of the middle belt is completed;

[0028] In the above process, in some construction scenarios, the operators can only use small-sized tamping machines with relatively low power to tamp the soil. At this time, when too much soil is transported at one time, the small-sized tamping machine cannot tamp the thicker soil layer with sufficient effect, resulting in insufficient filling effect. For this reason, the conveying vehicle also includes a control module 3, and the conveying vehicle also includes a detection module. The detection module is used to detect the compaction degree of the previous layer of backfill soil. The control module 3 is electrically connected to the hopper 2 and the detection module respectively. The control module 3 increases the volume of the soil transported in a single batch when the compaction degree exceeds the threshold value, and reduces the volume of the soil transported in a single batch when the compaction degree is lower than the threshold value.

[0029] When in use, the hopper 2 pushes the push shovel 22 to transport soil in batches to one side of the transport vehicle 1. The detection module is used to detect the compactness of the previous layer of backfill soil. The control module 3 increases the volume of the soil transported in a single batch when the compactness exceeds the threshold, and reduces the volume of the soil transported in a single batch when the compactness is lower than the threshold.

[0030] At the same time, the detection module includes a probe 31 that can be close to or away from the soil layer and a plurality of pressure sensors arranged on the surface of the probe 31. The plurality of pressure sensors are electrically connected to the control module 3. The control module 3 drives the probe 31 to approach the soil layer. When the plurality of pressure sensors are in contact with the soil layer, the pressure from the soil layer on the probe 31 is uploaded to the control module 3. The control module 3 determines the compaction degree according to the pressure data. In this embodiment, a cantilever 32 is arranged at the rear of the transport vehicle 1. The probe 31 is arranged at one end of the cantilever 32. The cantilever 32 drives the probe 31 to approach the soil layer when detecting.

[0031] Meanwhile, a compaction threshold value M0 is pre-input into the control module 3. The detection module is used to detect the compaction degree M of the backfill soil of the upper layer and upload it to the control module 3. The control module 3 instructs the hopper 2 to batch-transport soil with a volume of V×A1 to one side of the transport vehicle 1, where A1 = M / M0×c, and c and V are pre-input constants;

[0032] When the compaction degree M detected by the control module 3 is relatively high, it means that the current process and equipment can better ensure the compaction degree of the upper layer of fill soil. At this time, the soil thickness of each layer of fill construction can be increased to improve the construction efficiency, and then the median strip can be filled as soon as possible to improve the construction efficiency. At this time, the value of A1 = M / M0×c is relatively large. When the control module 3 instructs the hopper 2 to batch-transport soil with a volume of V×A1 to one side of the transport vehicle 1, the construction efficiency is improved when the compaction degree is relatively high; similarly, when the value of M is relatively low, it means that the current process and equipment cannot better ensure the compaction degree of the upper layer of fill soil. At this time, the thickness of each layer of fill needs to be reduced so that the rammer can better compact each layer of fill. At this time, the value of A1 = M / M0×c is relatively small. When the control module 3 instructs the hopper 2 to batch-transport soil with a volume of V×A1 to one side of the transport vehicle 1, the filling effect is ensured when the compaction degree is relatively low;

[0033] By setting up a detection module to detect the compaction degree of each layer of fill soil, and adjusting the soil delivery volume of the next layer of fill according to the detection result, thereby adjusting the thickness of each layer of fill soil, the soil delivery volume is increased when the compaction degree is relatively high, thereby improving the construction efficiency, and the soil delivery volume is reduced when the compaction degree is relatively low, thereby reducing the thickness of each layer of fill soil to ensure the filling effect.

[0034] In the above process, specifically, the humidity of the backfill soil will also affect the filling effect. When the soil humidity is relatively high, the thickness of each layer of fill needs to be reduced to ensure that the soil with a relatively high humidity and relatively soft texture is fully compacted. For this reason, the detection module also includes a soil humidity sensor. The soil humidity sensor is used to detect the humidity of the backfill soil of the upper layer and upload it to the control module 3. The control module 3 reduces the volume of soil transported in a single batch when the humidity exceeds the threshold value, and the control module 3 increases the volume of soil transported in a single batch when the humidity is lower than the threshold value;

[0035] Specifically, the soil humidity sensor is used to detect the humidity S of the backfill soil of the upper layer and upload it to the control module 3. The control module 3 instructs the hopper 2 to batch-transport soil with a volume of V×A1×A2 to one side of the transport vehicle 1, where A2 = S0 / S×d, d is a pre-input constant, S≥S0, and when the detection result shows S < S0, S = S0 is taken;

[0036] When the soil moisture is high, the filling thickness of each layer needs to be reduced to ensure that the relatively soft soil with high moisture is fully compacted. At this time, the value of A2=S0 / S×d is low. When the control module 3 instructs the hopper 2 to transport the soil with a volume of V×A1×A2 in batches to one side of the transport vehicle 1, the filling thickness of each layer is corrected downward when the humidity is high to ensure that the relatively soft soil with high moisture is fully compacted.

[0037] When the soil moisture is low, there is no need to reduce the thickness of each layer of fill to ensure construction efficiency. At this time, the value of A2=S0 / S×d is high. When the control module 3 instructs the hopper 2 to transport the soil with a volume of V×A1×A2 in batches to one side of the transport vehicle 1, the thickness of each layer of fill is corrected upward when the humidity is high, ensuring that the humidity is low and the construction efficiency is improved without the need for full tamping;

[0038] By setting up humidity sensors to detect the soil and reducing the filling thickness when the soil humidity is high after filling, it is ensured that the relatively soft soil with high humidity is fully compacted, thereby improving the filling effect and improving the construction efficiency when the humidity is low and there is no need for full compaction.

[0039] During the transportation of soil, when it is not filled into the center dividing belt, there is a probability that the soil will clump in the hopper 2. After the clumped soil is filled into the center dividing belt, under the protection of other soils, the force of the tamping machine on the clumps cannot break the clumps, and the clumped soil is likely to be unable to be compacted by the tamping machine, affecting the filling effect. For this reason, the hopper 2 includes a vibrator, which is used to vibrate the soil in the hopper 2;

[0040] By providing a vibrator to vibrate the soil in the hopper 2, the influence of soil agglomeration on the filling effect is reduced.

[0041] In the above process, when the soil density is low, the agglomerated soil will further reduce the overall filling effect on the basis of the low density, that is, in this case, the filling effect is that the redundancy of the potential agglomerated soil is low, and at this time, it is necessary to further increase the vibration power to reduce the probability of soil agglomeration. When the soil density is high, the filling effect is that the redundancy of the potential agglomerated soil is high, and there is no need for excessively high vibration power to save energy. For this reason, the vibrator is electrically connected to the control module 3, and the control module 3 reduces the power of the vibrator when the density exceeds the threshold, and the control module 3 increases the power of the vibrator when the density is lower than the threshold;

[0042] Specifically, the control module 3 is pre-input with a reference power P0, and the control module 3 adjusts the power of the vibrator to P, where P=M0 / M×e×P0, and e is a pre-input constant;

[0043] When the compaction degree M is high, it means that the filling effect is a high redundancy of potential agglomerated soil, and there is no need for excessively high vibrating power. At this time, the value of P=M0 / M×e×P0 is low. When the control module 3 adjusts the power of the vibrator to P, the vibrating power is reduced when the compaction degree is high and the filling effect is good;

[0044] When the compaction degree M is low, it means that the filling effect in this case is low redundancy of potential agglomerated soil, and the vibration power needs to be further increased. At this time, the value of P=M0 / M×e×P0 is high. When the control module 3 adjusts the power of the vibrator to P, the vibration power is increased when the compaction degree is low and the filling effect is poor;

[0045] By making the control module 3 adjust the vibration power according to the density of the previous layer of fill, the vibration power is reduced when the density is high and the fill effect is that the redundancy of the potential agglomerated soil is high, and an excessively high vibration power is not needed; the vibration power is increased when the fill effect is that the redundancy of the potential agglomerated soil is low and the vibration power needs to be further increased.

[0046] In order to facilitate the input of constants such as M0, c, d, S0, M0 and e, a control panel is also included. The control panel is electrically connected to the control module 3 and is used to input the values ​​of M0, c, d, S0, M0 and e.

[0047] The working principle and use process of the present invention:

[0048] The hopper 2 pushes the shovel 22 to transport soil in batches to one side of the transport vehicle 1. The detection module is used to detect the density of the previous layer of backfill soil. The control module 3 increases the volume of the soil transported in a single batch when the density exceeds the threshold, and reduces the volume of the soil transported in a single batch when the density is lower than the threshold.
