[0002] The dam foundation refers to the basic component of the soil and rock layer that supports the dam structure. The dam foundation needs to have the ability to bear the gravity of the dam structure and store water pressure. Since the dam is a large-scale building facility, it is vital to the safety and stability of the dam. The bearing performance of the dam foundation is equally important. In the construction of the dam project, foundation tamping construction is a basic process link. A high degree of dam foundation tamping can ensure the bearing capacity and stability of the dam foundation.

During the tamping construction of the dam foundation, the soil foundation needs to be compacted and pressed to increase the bearing capacity of the dam foundation soil. However, during the tamping process of the soil foundation, loose soil will cause serious dust problems. The soil splashing will not only affect the normal work of the construction workers, but the dust will also seriously reduce the clarity of the construction workers' field of vision.

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model proposes a dam foundation compaction dust prevention device, including a base 1, a safety protection component and an anti-dust component: a construction box 2 is fixedly connected to the base 1, a support leg 3 is fixedly connected to the bottom of the base 1, a movable bottom wheel 26 is installed at the bottom of the support leg 3, a lifting screw 4 is rotatably connected to the inner bottom surface of the construction box 2, a rotating motor 23 is fixedly connected to the top of the construction box 2, the upper end of the lifting screw 4 passes through the top of the construction box 2 and is fixedly connected to the output end of the rotating motor 23 through a coupling, a plurality of sliders 5 are threadedly connected to the lifting screw 4, each slider 5 is fixedly connected to an adapter plate 6, a limit rod is fixedly connected to the inner bottom surface of the construction box 2, a through hole is opened on the adapter plate 6, and the through hole matches the limit rod, a plurality of guide rods 7 are slidably connected to the base 1, a plurality of guide rods 7 are fixedly connected to the lower ends of the guide rods 7, and the adapter plate 6 is fixedly connected to the guide rods 7;

[0024] Start the rotating motor 23, and drive the lifting screw 4 to rotate forward and reverse periodically through the rotating motor 23, so that the slider 5 on the lifting screw 4 moves up and down. During the downward movement of the slider 5, the slider 5 can drive the guide rod 7 to move downward through the adapter plate 6, and then the weight block 8 at the lower end of the guide rod 7 is used to compact the soil of the dam foundation to ensure the bearing capacity and stability of the dam foundation.

[0025] like Figure 1-Figure 3As shown, the safety protection assembly includes a support rod 9 fixedly connected to the upper end of the guide rod 7, a sliding pad 24 is arranged at the end of the support rod 9, and the sliding pad 24 fits the inner wall of the construction box 2, a straight plate 10 is fixedly connected to the support rod 9 through a bracket, a sliding groove 11 is opened at the bottom of the base 1, a sleeve plate 12 is slidably connected in the sliding groove 11, a reinforcement bottom plate 25 is fixedly connected to the bottom of the sleeve plate 12, a soft gasket is arranged at the bottom of the reinforcement bottom plate 25, and a first compression spring 13 is fixedly connected between the bottom of the straight plate 10 and the inner bottom surface of the sleeve plate 12;

[0026] When the guide rod 7 moves downward, the straight plate 10 can be driven downward through the adapter plate 6, so that the sleeve plate 12, the first compression spring 13 and the reinforced bottom plate 25 at the bottom of the sleeve plate 12 move downward synchronously, so that the reinforced bottom plate 25 begins to contact the foundation, and the straight plate 10 continues to move downward and squeezes the first compression spring 13, so that the straight plate 10 can be elastically retracted into the sleeve plate 12, thereby adapting to the descending compaction operation of the weight block 8. At the same time, the reinforced bottom plate 25 can further support and fix the compaction device, reduce the vibration of the device caused by the weight block 8 compacting the foundation, and at the same time, the combined structure of the straight plate 10 and the sleeve plate 12 can withstand part of the splashing soil to ensure the safety of the construction workers.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the dust prevention assembly includes an eccentric wheel 14 fixedly connected to the upper end of the lifting screw 4, a piston cylinder 15 is fixedly connected to the top of the construction box 2, a piston plate 16 is sealingly and slidably connected in the piston cylinder 15, a piston rod 17 is fixedly connected to the piston plate 16, the end of the piston rod 17 passes through the axial side wall of the piston cylinder 15 and is fixedly connected to a retaining plate 18, a second compression spring 19 is fixedly connected between the retaining plate 18 and the piston cylinder 15, an annular through pipe 20 is fixedly connected to the upper end of the outer wall of the construction box 2, an atomizing nozzle 21 is arranged on the annular through pipe 20, a water storage tank 22 is fixedly connected to the top of the construction box 2, and the water storage tank 22 and the annular through pipe 20 are connected to the piston cylinder 15 through a connecting pipe;

[0028] When the lifting screw 4 rotates, the eccentric wheel 14 can be driven to rotate synchronously. When the protruding part of the eccentric wheel 14 gradually loses contact with the retaining plate 18, the second compression spring 19 pushes the retaining plate 18 through its own elastic mechanical energy, so that the piston rod 17 pulls the piston plate 16 to slide in a sealed manner in the piston cylinder 15, thereby reducing the pressure in the piston cylinder 15, so that water can be absorbed from the water tank 22 through the connecting pipe. When the protruding part of the eccentric wheel 14 contacts the retaining plate 18, the eccentric wheel 14 will push the piston rod 17 by squeezing the retaining plate 18, so that the piston rod 17 pushes the piston plate 16 to slide in a sealed manner in the piston cylinder 15, thereby increasing the pressure in the piston cylinder 15, so that the piston cylinder 15 injects water into the annular pipe 20 through the connecting pipe, and sprays water mist around the compacting device through the atomizing nozzle 21 on the annular pipe 20, thereby effectively controlling the dust raised around the device and ensuring the clarity of vision of the construction personnel.

[0029] The detailed working process of the utility model is as follows:

[0030] 1. When in use, first start the rotating motor 23, and drive the lifting screw 4 to rotate forward and reverse periodically through the rotating motor 23, so that the slider 5 on the lifting screw 4 is lifted and moved. During the downward movement of the slider 5, the slider 5 can drive the guide rod 7 to move downward through the adapter plate 6, and then the weight block 8 at the lower end of the guide rod 7 is used to compact the dam foundation soil. In this process, the adapter plate 6 at the upper end of the guide rod 7 drives the straight plate 10 to move downward, so that the sleeve plate 12, the first compression spring 13 and the reinforcement bottom plate 25 at the bottom of the sleeve plate 12 move downward synchronously, so that the reinforcement bottom plate 25 begins to contact the foundation, and the straight plate 10 continues to move downward and squeezes the first compression spring 13, so that the straight plate 10 can be elastically retracted into the sleeve plate 12, so as to adapt to the descending compaction operation of the weight block 8. At the same time, the reinforcement bottom plate 25 can further support and fix the compaction device to reduce the vibration of the device caused by the weight block 8 compacting the foundation. At the same time, the combined structure of the straight plate 10 and the sleeve plate 12 can resist part of the splashing soil to ensure the safety of the construction personnel.

[0031] 2. When the lifting screw 4 rotates, the eccentric wheel 14 will rotate synchronously. When the protruding part of the eccentric wheel 14 gradually loses contact with the butt plate 18, the second compression spring 19 pushes the butt plate 18 through its own elastic mechanical energy, so that the piston rod 17 pulls the piston plate 16 to slide in a sealed manner in the piston cylinder 15, thereby reducing the pressure in the piston cylinder 15, so that water can be sucked from the water tank 22 through the connecting pipe. When the protruding part of the eccentric wheel 14 contacts the butt plate 18, the eccentric wheel 14 will push the piston rod 17 by squeezing the butt plate 18, so that the piston rod 17 pushes the piston plate 16 to slide in a sealed manner in the piston cylinder 15, thereby increasing the pressure in the piston cylinder 15, so that the piston cylinder 15 injects water into the annular pipe 20 through the connecting pipe, and sprays water mist around the compacting device through the atomizing nozzle 21 on the annular pipe 20, thereby effectively controlling the dust raised around the device and ensuring the clarity of vision of the construction personnel.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
