Description

Technical Field

[0001] The present invention relates to the technical field of soft soil solidification, and in particular to a soft soil solidification treatment device. Background Art

[0002] The Soft Soil Solidification Mixer is a mechanical device specifically designed for soil improvement and foundation reinforcement. It is primarily used in soft foundation treatment and deep mixing pile construction. This technology mixes cement or other curing agents with in-situ soft soil to create a modified soil with higher strength and lower compressibility, thereby enhancing the bearing capacity and stability of the foundation.

[0003] Currently, after using an excavator equipped with a soft soil solidification mixer to mix cement or other curing agents with the in-situ soft soil, the excavator is then equipped with a bucket to flatten and compact the soil. After solidification, the slag and soil are backfilled sequentially to ensure the foundation has a long-term and stable bearing capacity. However, during the flattening and compacting of the soil, since air bubbles cannot be removed from the soil, the porosity of the solidified soil cannot be reduced, which affects the durability and structural strength of the solidified soil.

[0004] In addition, although traditional concrete vibrators can expel air bubbles from concrete through vibration and improve the density and ultimate structural strength of newly poured concrete, soft soil is different from newly poured concrete and has stronger viscosity. It is inconvenient for workers to frequently insert, remove and vibrate the soft soil with handheld concrete vibrators. Summary of the Invention

The motor 107 drives the eccentric weight 105 to rotate inside the vibration tube 101. The vibration tube 101 vibrates at a high frequency to vibrate the soft soil and expel air bubbles in the soft soil. The stirring mechanism 20 is provided with a pair of symmetrically arranged on the left and right sides of the vibration tube 101. The stirring mechanism 20 includes a side strip 201, a stirring head 203 and a feeding pipe 206. The stirring head 203 is arranged at the lower end of the side strip 201. The motor 107 drives the stirring head 203 to rotate at the lower end of the vibration tube 101. The feeding pipe 206 transports the curing agent to between the left and right stirring heads 203. The rotating stirring heads 203 mix the soft soil and the curing agent. The switching mechanism 30 is arranged inside the vibration tube 101 and includes a second motor 301. When the second motor 301 rotates forward, it drives the side mounting strips 201 to be tightly attached to the left and right sides of the vibration tube 101. At this time, the device is in a stirring working mode. When the second motor 301 rotates reversely, it drives the side mounting strips 201 to be flattened on the left and right sides of the vibration tube 101. At this time, the device is in a vibration working mode.

[0028] In this embodiment, a mounting seat 102 is fixed to the top of the vibration tube 101, and a mounting shaft 103 is coaxially provided inside the vibration tube 101. The mounting shaft 103 is rotatably connected to the vibration tube 101 through a pair of bearing seats 104, and a number of eccentric blocks 105 are installed at intervals on the mounting shaft 103. The bottom end of the mounting shaft 103 is keyed to a friction wheel 106, and the motor 107 is arranged at the lower part of the vibration tube 101 through a motor seat 108. The motor 107 is arranged vertically upward and is keyed to a friction wheel 2 109 at its output end, and the upper end surface of the friction wheel 2 109 is frictionally engaged with the lower end surface of the friction wheel 106. When friction wheel 106 and friction wheel 2 109 are frictionally engaged, motor 107 drives the eccentric block 105 on the mounting shaft 103 to rotate in the vibration tube 101 through friction transmission between the friction wheels 106 and 109, and causes the vibration tube 101 to generate high-frequency vibration. The high-frequency vibration of the vibration tube 101 vibrates the soft soil and expel air bubbles in the soft soil.

[0029] In this embodiment, a rectangular avoidance opening 101a is symmetrically distributed on the upper part of the vibration tube 101, and a circular avoidance opening 2 101b is symmetrically distributed on the lower part of the vibration tube 101. The top of the side mounting strip 201 is located at the avoidance opening 101a and is rotatably connected to the vibration tube 101 through a rotating shaft 202. The stirring head 203 is rotatably connected to the bottom end of the side mounting strip 201 through a stirring shaft 204. The inner end key of the stirring shaft 204 is connected to a friction wheel 3 205, and the outer circumferential surface of the friction wheel 3 205 is frictionally fitted with the lower end surface of the friction wheel 2 109. The feeding tube 206 is an L-shaped structure and is fixed to the front side of the vibration tube 101 through a number of fixing seats 207. When the friction wheel 2 109 and the friction wheel 3 205 are frictionally engaged, the motor 107 drives the stirring head 203 on the stirring shaft 204 to rotate at the lower end of the vibration tube 101 after the friction transmission between the friction wheel 2 109 and the friction wheel 3 205. At the same time, the curing agent is transported to the space between the left and right stirring heads 203 through the feeding pipe 206, and the soft soil and the curing agent are mixed by the rotating stirring heads 203.

[0030] In this embodiment, the motor 2 301 is installed on the upper part of the vibration tube 101 through the motor base 2 302. The motor 2 301 is vertically upward and is connected to a screw 304 at its output end through a coupling 303. The screw 304 is connected to a sliding plate 306 through a screw nut 305, and the sliding plate 306 is slidably connected to the vibration tube 101. A "J"-shaped fixed frame 307 is connected in the center of the upper side of the sliding plate 306, and racks 308 are vertically connected to the left and right sides of the fixed frame 307. The key on the rotating shaft 202 A gear 309 is connected, and the gear 309 and rack 308 on the same side mesh with each other. A sliding frame 310 is provided directly above the motor base 108, and a plurality of steel segments 311 are evenly connected between the sliding frame 310 and the motor base 108. The sliding frame 310 is slidably connected to the vibration tube 101. A plurality of fixed pulleys 312 are evenly connected to the bottom surface of the mounting base 102. Each fixed pulley 312 is threaded with a steel wire rope 313, and the ends of the steel wire rope 313 are respectively connected to the sliding plate 306 and the sliding frame 310. The forward rotation of the motor 2 301 drives the rack 308 upward. After transmission between the gear 309 and the rack 308, the side mounting strips 201 are pressed against the left and right sides of the vibration tube 101, and the friction wheels 3 205 and friction wheels 2 109 on both sides are frictionally engaged. At this time, the device is in a mixing mode and is used to mix soft soil and curing agent. The motor 2 301 reverses and drives the rack 308 to move downward. After transmission between the gear 309 and the rack 308, the side strips 201 are flattened on the left and right sides of the vibration tube 101. Under the traction of the wire rope 313, the friction wheel 2 109 and the friction wheel 1 106 are driven to frictionally cooperate. At this time, the device is in the vibration working mode and is used to expel air bubbles in the soft soil.

[0031] In this embodiment, mounting holes 102a are symmetrically distributed on the left and right sides of the mounting base 102. The mounting holes 102a on the mounting base 102 facilitate the installation of the device on the end of the mechanical arm of the excavator.

[0032] In this embodiment, angle iron blocks 110 are symmetrically fixed to the lower portion of the vibration tube 101, and compression springs 111 are connected between the angle iron blocks 110 and the motor base 108. The compression springs 111 can effectively support the motor 107 on the motor base 108 and automatically reset it.

[0033] In this embodiment, the mixing head 203 includes a mounting barrel 2031. A spiral mounting strip 2032 is fixed to the outer circumference of the mounting barrel 2031. Several mounting plates 2033 are spaced apart and connected to the mounting strip 2032. A stirring blade 2034 is vertically fixed to the side of each mounting plate 2033. A mounting disc 2035 is coaxially fixed to the outer end surface of the mounting barrel 2031. A circular array of stirring bars 2036 is distributed on the outer end surface of the mounting disc 2035. The stirring blades 2034 and stirring bars 2036 thoroughly mix the soft soil and the curing agent.

[0034] In this embodiment, the vibration tube 101 has a pair of parallel guide bars 314 located on either side of the second avoidance opening 101b. A side baffle 315 is slidably connected between the guide bars 314. Two steel bars 316 are vertically connected between the side baffles 315 and the sliding plate 306. When the device is in vibration mode, the side baffles 315 are inserted into the exposed interior of the second avoidance opening 101b to prevent soft soil and moisture from entering the vibration tube 101 through the second avoidance opening 101b, thereby preventing contamination and damage to mechanical components.

[0035] The working principle of this soft soil solidification treatment device: (1) Mixing working mode: Motor 2 301 rotates forward and drives rack 308 upward. After transmission between gear 309 and rack 308, side mounting strips 201 are pressed against the left and right sides of vibrating tube 101. Friction wheels 3 205 and 209 on both sides engage with each other. The device is now in a stirring mode, mixing soft soil with a curing agent. When friction wheels 2 109 and 3 205 engage with each other, motor 107, through friction transmission between friction wheels 2 109 and 3 205, drives stirring head 203 on stirring shaft 204 to rotate at the lower end of vibrating tube 101. Simultaneously, curing agent is delivered between left and right stirring heads 203 via feed pipe 206, whereupon the rotating stirring heads 203 mix the soft soil and curing agent.

[0036] (2) Vibration working mode: Motor 2 301 reverses and drives rack 308 downward. After transmission between gear 309 and rack 308, side mounting strips 201 are flattened on the left and right sides of vibration tube 101. The friction wheel 2 109 and friction wheel 1 106, pulled by wire rope 313, engage frictionally. The device is now in vibration mode and is used to expel air bubbles from the soft soil. When friction wheels 1 106 and 109 engage frictionally, motor 1 107, through friction transmission between friction wheels 1 106 and 109, drives eccentric block 105 on mounting shaft 103 to rotate within vibration tube 101, generating high-frequency vibrations in vibration tube 101. This high-frequency vibration of vibration tube 101 vibrates the soft soil and expels air bubbles from it, thereby reducing the porosity of the solidified soil and improving its durability and structural strength.

[0037] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
