Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a highway roadbed gravel pile. Background Art

[0002] Gravel piles are composite foundation reinforcement piles made of gravel as the main material. Gravel piles and sand piles are collectively referred to as loose piles or coarse-grained soil piles abroad. The so-called loose piles refer to piles without bonding strength. The composite foundation composed of loose piles such as gravel columns or sand piles and soil between piles can also be called loose pile composite foundation. The gravel piles, sand piles, slag piles and other composite foundations widely used at home and abroad are all loose pile composite foundations. The existing gravel piles are basically used in conjunction with a hollow tube, and then a ground-breaking cone is added. After the gravel pile is placed inside the hollow tube, the whole is inserted into the ground through the ground-breaking cone to realize the ground insertion operation of the gravel pile.

[0003] The existing public patent number is: CN219100043U, which discloses a highway roadbed gravel pile, including a fixed plate and a fixed ring, which are connected by a protective net, a support plate is symmetrically fixedly connected to the surface of the protective net, a gravel column is arranged inside the protective net, an iron impact hammer is arranged above the gravel column, an electromagnet is fixedly installed on the top of the fixed plate, a pressure plate is arranged above the iron impact hammer, a mounting frame is arranged above the fixed plate, a first threaded rod is rotatably connected to the bottom of the mounting frame, the first threaded rod is threadedly connected to the fixed plate, the first threaded rod is rotatably connected to the top of the pressure plate, a mounting block is symmetrically fixedly installed on the outer surface of the fixed ring, a ground-inserting rod is fixedly connected to the bottom of the mounting block, and an internal support mechanism is arranged inside the ground-inserting rod.

[0004] The above scheme has a compact structure and strong practicality. The electromagnet cooperates with the iron impact hammer to impact the gravel column, making the whole body deeper into the ground, while compacting the gravel column to make it fit closely with the protective net to improve the overall stability. When the gravel column of the device hits the ground, a large amount of dust will be generated, resulting in a large amount of dust, affecting the surrounding environment. At the same time, when the staff are performing pile foundation operations, the large amount of dust reduces the working environment of the staff.

[0005] Utility model content.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a highway roadbed gravel pile, comprising: a bracket base, a U-shaped bracket is fixedly connected to the top of the outer surface of the bracket base, a water tank is fixedly connected to the outer surface of the bracket base, a nozzle is fixedly connected to the bottom of the outer surface of the water tank, the top of the outer surface of the U-shaped bracket is fixedly connected to the U-shaped bracket, the top of the outer surface of the U-shaped bracket is fixedly connected to a motor, the output end of the motor is fixedly connected to a hydraulic cylinder, and the bottom end of the hydraulic cylinder is fixedly connected to a drill bit.

[0007] The technical effect of adopting the above further scheme is: when the pressure plate moves downward, the pressure plate releases the pressure through the nozzle at the bottom of the water tank.

[0011] The technical effect of adopting the above further solution is: when the motor is started, it drives the circular shaft 1 to rotate at the same time, and the circular shaft 1 drives the circular shaft 2 to rotate through the belt.

[0012] As a preferred embodiment, the bottom end of the reciprocating screw is fixedly connected to a round rod, the round rod is rotatably connected to the top of the outer surface of the bracket base through a bearing, and the top of the outer surface of the water tank is fixedly connected to an extrusion cylinder.

[0014] As a preferred embodiment, a pressure plate is movably embedded inside the extrusion cylinder, a linkage device is fixedly connected to the top of the outer surface of the pressure plate, and the linkage device is movably sleeved on the outer surface of the reciprocating screw.

[0015] The technical effect of adopting the above further solution is: the pressure plate is driven to slide on the inner wall of the extrusion cylinder through the linkage device, and when the linkage device slides upward, the gas comes out from the small hole above.

[0016] As a preferred embodiment, a limiting device is fixedly connected to the top of the outer surface of the extrusion cylinder, a movable disk is slidably connected inside the limiting device, and a second magnet is fixedly connected to the bottom of the outer surface of the movable disk.

[0017] The technical effect of adopting the above-mentioned further scheme is: when the pressure plate moves upward, the movable plate slides upward inside the limit device, and after sliding, the gas inside the extrusion cylinder comes out from the small hole. The linkage device moves upward faster and the air resistance force is smaller. At the same time, when the pressure plate moves downward, the pressure plate releases the pressure through the nozzle at the bottom of the water tank.

[0018] As a preferred embodiment, a small hole is opened at the top of the outer surface of the extrusion cylinder, and a magnet one is fixedly connected to the inner wall of the small hole, and the magnet one is movably connected to the outer surface of the magnet two.

When the pressure plate 113 moves downward, the pressure plate 113 dissipates the pressure through the nozzle 119 at the bottom of the water tank 118, and at the same time, the moisture inside the water tank 118 is pressed out by the nozzle 119 due to the pressure and sprayed to the drilling hole of the drill bit 121 to reduce dust.

[0031] like Figure 1-4 As shown, threaded rods 102 are movably embedded around the outer surface of the bracket base 101, and the bottom of the threaded rods 102 is fixedly connected to the chassis 103. When the threaded rods 102 are rotated around the bracket base 101 so that the chassis 103 supports the bracket base 101, the bracket base 101 is always in a horizontal state.

[0032] like Figure 1-4 As shown, the output end of the motor 105 is fixedly connected to a circular shaft 106, the outer surface of the circular shaft 106 is movably sleeved with a belt 107, one end of the belt 107 is movably sleeved with a circular shaft 2 108, and the bottom of the outer surface of the circular shaft 2 108 is fixedly connected to a reciprocating screw 109. When the motor 105 is started, it also drives the circular shaft 106 to rotate, and the circular shaft 106 drives the circular shaft 2 108 to rotate through the belt 107.

[0033] like Figure 1-4 As shown, the bottom end of the reciprocating screw 109 is fixedly connected to a round rod 110, and the round rod 110 is rotatably connected to the top of the outer surface of the bracket base 101 through a bearing. The top of the outer surface of the water tank 118 is fixedly connected to an extrusion cylinder 112. When the round shaft 108 rotates, it drives the reciprocating screw 109 and the round rod 110 to rotate. At this time, the linkage device 111 slides back and forth up and down on the outer surface of the reciprocating screw 109.

[0034] like Figure 1-4 As shown, a pressure plate 113 is movably embedded inside the extrusion cylinder 112, and a linkage device 111 is fixedly connected to the top of the outer surface of the pressure plate 113. The linkage device 111 is movably sleeved on the outer surface of the reciprocating screw 109.

At the same time, when the motor 105 is started, it also drives the circular shaft 106 to rotate. The circular shaft 106 drives the circular shaft 2 108 to rotate through the belt 107. When the circular shaft 2 108 rotates, it drives the reciprocating screw rod 109 and the circular rod 110 to rotate. At this time, the linkage device 111 slides back and forth up and down on the outer surface of the reciprocating screw rod 109. After sliding, The pressure plate 113 is driven to slide on the inner wall of the extrusion cylinder 112 through the linkage device 111. When the linkage device 111 slides upward, the gas comes out from the small hole above. It should be noted that the pressure of the gas is greater than the magnetic force between the magnet 117 and the magnet 117. When the pressure plate 113 moves upward, the movable plate 115 slides upward inside the limit device 114. After sliding, the gas inside the extrusion cylinder 112 comes out from the small hole. The linkage device 111 moves upward faster and the air resistance is smaller. At the same time, when the pressure plate 113 moves downward, the pressure plate 113 releases the pressure through the nozzle 119 at the bottom of the water tank 118. At the same time, the water inside the water tank 118 is pressed out by the nozzle 119 due to the pressure and sprayed onto the drilling hole of the drill bit 121 to reduce dust.
