Description

TECHNICAL FIELD

[0001] The present application relates to the field of earthwork filling, in particular to an earthwork filling control device and method. BACKGROUND

[0002] During the construction of a hydropower station, pipeline systems need to be laid out, trenches are excavated on the ground according to design drawings, and then the pipelines are laid in the trenches section by section, and then water pressure debugging is carried out. After that, when the trench earthwork is filled, the soil excavated from the trench has been trampled, squeezed and rammed by construction personnel and other construction equipment since the trench was excavated. At the same time, some debris generated during pipeline construction is also mixed in the excavated soil, which cannot be used as filling material to fill the trench. New filling material needs to be replaced. At the same time, considering the protection of the pipeline, special filling material such as lime soil filling material is generally required, which has high strength and can resist stronger external squeezing force to ensure the stability of the environment where the pipeline system is located.

[0003] The existing filling method generally uses excavators to fill the earthwork step by step, and then manually spreads the filling material, and finally a ramming machine is used to compact the filling material. The filling material not only contains pure clay, but also contains lime. The excavator is limited to filling the single filling material in turn, which leads to uneven mixing of the clay and lime. If the filling material is mixed in advance, uniform mixing of the filling material can be achieved. However, lime is prone to chemical reaction when it comes into contact with moisture in the air, turning into calcium carbonate, which makes the filling material hard and difficult to compact in the later filling process, and also hinders the manual spreading of the filling material.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0038] Reference Figure 1 - Figure 11The utility model provides a kind of earth filling control device, including board car 1, the front end of the board car 1 is fixedly connected with link plate 2, multiple fixed holes are set on the link plate 2, the upper surface of the board car 1 is equipped with feeding unit, the feeding unit can evenly feed filler into the groove of ground, the rear end of the board car 1 is symmetrically fixedly connected with traction rod 9, the end of the traction rod 9 is equipped with rolling unit, the rolling unit can roll the material that feeding unit feeds flat, the rolling unit is equipped with tamping assembly, tamping assembly can tamp the material that rolling flat;

[0039] First, the earth filling control device is erected above the groove, so that the wheel body of the board car 1 is placed on both sides of the groove and rolls, and is slowly moved along the groove direction by the construction vehicle in front, while the excavator is used to feed clay and hydrated lime into the feeding unit, the clay and hydrated lime in the feeding unit are mixed, and then fed into the groove, and then the rolling unit rolls the filler at the position of the groove, and the rolling unit drives the tamping assembly to tamp the rolled filler;The earth filling control device not only can uniformly mix clay and hydrated lime to ensure the performance of the filler, but also can separate the feeding of clay and hydrated lime, fully utilize the hydrated lime material and avoid the waste of hydrated lime.

[0040] Referring to Figure 1 - Figure 5 The feeding unit includes feeding assembly, which includes flared portion 3, intermediate pipe 4 and discharge pipe 5;The upper end of the intermediate pipe 4 is fixedly connected with the flared portion 3, and the outer two side walls of the intermediate pipe 4 are symmetrically fixedly connected with hydraulic cylinders 6, the cylinder body of the hydraulic cylinders 6 is fixedly connected with the board car 1, the lower end of the intermediate pipe 4 is fixedly connected with the discharge pipe 5 which is in the shape of a neck, and the discharge pipe 5 is provided between the intermediate pipe 4 and the discharge auger 7, one end of the discharge auger 7 is rotatably connected with the lower end of the discharge pipe 5, the upper end of the discharge auger 7 is inclined towards the position where the intermediate pipe 4 and the discharge pipe 5 are fixedly connected, and the upper end of the discharge auger 7 is fixedly connected with a drive motor 8, and the drive motor 8 is fixedly connected with the intermediate pipe 4;The clay and hydrated lime material is fed from the flared portion 3 into the intermediate pipe 4, the drive motor 8 drives the discharge auger 7 to rotate, which stirs the clay and hydrated lime material while pushing the mixed filler into the groove, and the rotating discharged filler falls into the groove, filling the groove, and the filler protrudes above the groove opening level, ensuring effective filling of the groove;

[0041] As for the height of the filler protruding above the groove opening level, it can be achieved by driving the feeding assembly to move up and down by the hydraulic cylinders 6, driving the feeding assembly to lift to a certain height by the hydraulic cylinders 6, increasing the height between the discharge pipe 5 and the groove opening level, so that the groove can be flattened after being filled and rolled and tamped.

[0042] Referring to Figure 1 - Figure 5The compaction unit includes crossbars 10 symmetrically arranged on both sides of the traction rod 9. The ends of the crossbars 10 are rotatably connected to the ends of the traction rod 9. Multiple rollers 11 are rotatably connected between the crossbars 10. A compaction component is set at the rear of the rollers 11. The trolley 1 drives the compaction unit to move through the traction rod 9. The rollers 11 rotate and compact the filler, flattening the protruding filler. Due to the constricted design of the lower end of the feed pipe 5, the filler will be concentrated in the middle of the groove. When the rollers 11 are compacting the protruding filler, they will concentrate on filling the middle of the groove. This is also a more ideal situation, so as to prevent the filler from being distributed near the outer side of the groove and discharged outside the groove after being compacted by the rollers 11, resulting in ineffective filling.

[0043] Reference Figure 1 - Figure 6 The compaction assembly includes a middle plate 12 with U-shaped ends. The outer walls of the middle plate 12 are fixed to a crossbar 10. An I-shaped compaction plate 13 is slidably connected inside the middle plate 12. A top block 14 is provided on the surface of the compaction plate 13 opposite to the roller 11. The end of the top block 14 extends into an annular groove 15 opened on the outer surface of both ends of the roller 11. Multiple impact blocks 16 are uniformly fixed in the annular groove 15. The impact blocks 16 can rotate and push the top block 14 upward. The lower surface of the upper end of the compaction plate 13 is connected to the upper surface of the middle plate 12 by multiple springs. The roller 11 rotates while driving the impact block 16 to make a circular motion. The impact block 16 rotates counterclockwise and intermittently pushes the top block 14 upward. The top block 14 drives the tamping plate 13 to move upward. When the impact block 16 is separated from the top block 14, the tamping plate 13 loses the upward pressing force of the impact block 16. The tamping plate 13 relies on its own weight to impact the filling material, thereby further compacting the filling material. As for the compaction strength and the compaction density of the filling material, multiple rolling units are set up with the same number of tamping components. At the same time, the mass of the tamping plate 13 is increased. A metal with a higher density can be selected to ensure the quality of trench filling.

[0044] Reference Figure 1 - Figure 5 A dust suppression component is provided between the trolley 1 and the flared section 3. The dust suppression component includes a water tank 17 and a pump body. The water inlet of the pump body is connected to the water tank 17, and the water outlet of the pump body is connected to a flexible hose 18. The flexible hose 18 is coiled around the outside of the flared section 3. Multiple atomizing nozzles 19 are provided on the inner surface of the upper port of the flared section 3. The atomizing nozzles 19 are connected to the flexible hose 18. The quicklime used is in powder form, which is easy to obtain and also facilitates uniform mixing with clay. However, the powdered quicklime will generate dust during the feeding process. Therefore, the dust suppression component is set up. The atomizing nozzles 19 discharge water mist to suppress the dust and provide a good working environment for the construction personnel.

[0045] Reference Figure 4 ,Figure 5 、 Figure 8 、 Figure 9 and Figure 10 , the flared portion 3 and the intermediate tube 4 are provided with a screening assembly; the screening assembly comprises two screen plates 20 arranged in upper and lower positions, and the screen plate 20 is provided with a strip-shaped mesh 21; a sliding port is formed at the position where the flared portion 3 and the intermediate tube 4 are fixedly connected, the sliding port is provided through in the direction of the hydraulic cylinder 6, the screen plate 20 can be slidably connected in the sliding port, and the hydraulic cylinder 6 is higher than the intermediate tube 4 and is fixedly provided with a driving assembly; the driving assembly comprises a motor 22, a rotating disc 23 and a push-pull rod 24; the motor 22 is fixedly connected to the intermediate tube 4, the output end of the motor 22 is fixedly connected with the rotating disc 23, one end of the rotating disc 23 is rotatably connected to the push-pull rod 24, and the other end of the push-pull rod 24 is rotatably connected to the intermediate position of the end of the screen plate 20; the slaked lime is prepared by adding water to the quicklime, and the powdery slaked lime will leave some blocky agglomerates, and there will also be some agglomerates in the clay, which will not be uniformly mixed in the later stage. Therefore, the screening assembly is arranged, the two screen plates 20 are arranged in upper and lower positions, and the filler can be sheared and broken by the screen plate 20 when passing through the screen plate 20, so that the fineness of the filler is improved, which is helpful for the mixing of the filler and also helps the filler to be scattered in the groove;

[0046] The upper and lower screen plates 20 move back and forth intermittently, the motor 22 drives the rotating disc 23 to rotate, and the rotating disc 23 intermittently pushes and pulls the push-pull rod 24, so that the screen plate 20 reciprocates; in order to improve the relative movement smoothness between the upper and lower screen plates 20 in the embodiment, rolling grooves 33 are formed on the upper and lower surfaces of the two sides of the screen plate 20, and rolling balls 32 are rotatably arranged in the rolling grooves 33, so that the sliding friction between the upper and lower screen plates 20 is converted into the rolling friction between the rolling balls 32 and the screen plate 20, and the friction is reduced.

[0047] Referring to Figure 8 、 Figure 9 and Figure 10 , a plurality of baffles 25 are fixedly connected to the upper screen plate 20 perpendicularly, and adjacent two rows of baffles 25 are arranged in a staggered manner; the sliding port is arranged obliquely to the rolling unit, a discharge port 26 is formed in the bottom of the flared portion 3 close to the rolling unit, a guide plate 27 is arranged below the outer side of the discharge port 26, and the guide plate 27 is arranged obliquely to the ground; the oblique arrangement of the sliding port to the rolling unit also makes the upper and lower screen plates 20 oblique to the rolling unit, and the baffles 25 are arranged to block the filler passing through the mesh 21, so as to prevent the filler from sliding out of the discharge port 26 and causing waste of the filler. Some particulate matters may be contained in the clay in the filler, and some particulate matters that have not reacted with water may be contained in the quicklime. These particulate matters cannot pass through the mesh 21 and will gradually slide to the position of the discharge port 26 under the oblique trend of the screen plate 20, and then slide onto the guide plate 27 and be discharged from the construction site. The first reason is to prevent the particulate matters from blocking the screen plate 20, and the second reason is to prevent the particulate matters from being mixed into the filler, which may cause extrusion damage to the pipeline.

[0048] With reference to Figure 5 , and Figure 7 , the shaft body of the discharging auger 7 is hollow, a plurality of water injection holes 28 are arranged on the surface of the shaft body, a hollow ring body 29 is rotatably connected to the outer ring of the upper end of the shaft body, the inner ring of the hollow ring body 29 is communicated with the inside of the shaft body, and the outer ring of the hollow ring body 29 is communicated with a water pipe 30 which penetrates to the outside of the intermediate pipe 4 and is connected to the water tank 17 through a water pump; after the filling of the trench is completed, the discharging auger 7 and the material feeding assembly need to be cleaned, and the filler adheres to the surface, which affects the next use. Therefore, water is discharged from the water injection holes 28 on the surface of the hollow shaft body of the discharging auger 7, so as to realize self-cleaning of the discharging auger 7, and the rotating discharging auger 7 can clean the material feeding assembly. Moreover, if the humidity of the filler does not meet the requirements, it will also affect the filling construction quality. If the humidity of the filler is too small, the discharging auger 7 can be used for water supplement, and the water directly overflows from the inside of the filler, which is helpful for the sufficient mixing of water and filler.

[0049] With reference to Figure 11 , the outer ring of the roller body 11 is provided with a protrusion 31 which is annular and wrapped and fixed on the surface of the roller body 11. The protrusion 31 is arranged in the shape of a ring, and the distance between the two ends of the protrusion 31 is less than the width of the trench, so that the filler can be fully extruded at the middle position of the trench, and the amount of filler extruded out of the trench is reduced.

[0050] With reference to Figure 12 , a kind of earth filling control method, the method is suitable for any one of the above earth filling control device, the earth filling control method includes the following steps:

[0051] S1: pipeline trench cleaning, clean up the foreign matter in the trench, so that foreign matter is not extruded pipeline when being rammed;

[0052] S2: filling and rolling experiment, measure the extrusion force of pipeline in the process of pressure filling and ramming, so as to prevent the extrusion damage of pipeline connection position;
