Description

Technical Field

[0001] This invention relates to the technical field of soft soil solidification, and specifically to a soft soil solidification treatment device. Background Technology

[0002] The soft soil solidification mixing head is a mechanical device specifically designed for soil improvement and foundation reinforcement, mainly used in the treatment of weak foundations and the construction of deep mixing piles. This technology mixes cement or other solidifying agents with in-situ soft soil to form improved soil with higher strength and lower compressibility, thereby enhancing the bearing capacity and stability of the foundation.

[0003] Currently, after mixing cement or other hardeners with in-situ soft soil using an excavator equipped with a soft soil hardening mixing head, the excavator is then used with a bucket to level and compact the land. After solidification, slag and excavated soil are backfilled sequentially to ensure the foundation has a long-lasting and stable bearing capacity. However, during the leveling and compaction process, air bubbles cannot be expelled from the soil, thus failing to reduce the porosity of the solidified soil. This affects the durability and structural strength of the solidified soil.

[0004] In addition, although traditional concrete vibrators can remove air bubbles in concrete and improve the density and final structural strength of freshly poured concrete, soft soil is different from freshly poured concrete. It is more cohesive, and it is inconvenient for workers to frequently insert and remove the concrete vibrator and vibrate it. Summary of the Invention

[0005] The purpose of this invention is to provide a soft soil solidification treatment device to solve the above-mentioned defects caused by the prior art.

[0006] A soft soil solidification treatment device includes a vibration mechanism, a mixing mechanism, and a switching mechanism, wherein...

And the outer circumferential surface of the third friction wheel is in frictional cooperation with the lower end surface of the second friction wheel. The feeding pipe is of an L-shaped structure and is fixed to the front side of the vibration tube through a number of fixing seats.

[0012] Preferably, the second motor is installed on the upper part of the vibration tube through a second motor seat. The second motor is arranged vertically upward and is connected with a lead screw at its output end through a coupling. The lead screw is connected with a sliding plate through a lead screw nut. And the sliding plate is slidably connected to the inside of the vibration tube. The upper side of the sliding plate is centrally connected with a "channel-shaped" fixing frame, and racks are vertically connected to the left and right sides of the fixing frame. A gear is key-connected to the rotating shaft. The gears and the racks on the same side are meshed with each other. A sliding frame is connected above the first motor seat, and a number of steel bar segments are evenly connected between the sliding frame and the first motor seat. The sliding frame is slidably connected to the inside of the vibration tube. The bottom surface of the mounting seat is evenly connected with a number of fixed pulleys. A steel wire rope is threaded through each fixed pulley, and the two ends of the steel wire rope are respectively connected to the sliding plate and the sliding frame.

[0013] Preferably, mounting holes are symmetrically distributed on the left and right sides of the mounting seat.

[0018] 1. The present invention consists of a vibration mechanism, a stirring mechanism and a switching mechanism, including a stirring working mode and a vibration working mode, and can automatically switch between the two working modes through the switching mechanism, avoiding manual disassembly and debugging of different functional modules.

[0019] 2. When the present invention is in the stirring working mode, when friction wheel two and friction wheel three are in frictional engagement, motor one drives the stirring head on the stirring shaft to rotate at the lower end of the vibrating tube after frictional transmission between friction wheel two and friction wheel three. At the same time, the curing agent is transported to the left and right stirring heads through the feeding pipe, and the soft soil and curing agent are mixed by the rotating stirring head.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 8 As shown, a soft soil solidification treatment device includes a vibration mechanism 10, a mixing mechanism 20, and a switching mechanism 30, wherein...

[0035] The vibration mechanism 10 includes a vibration tube 101, an eccentric block 105, and a motor 107. The motor 107 drives the eccentric block 105 to rotate inside the vibration tube 101. The vibration tube 101 vibrates the soft soil and discharges air bubbles in the soft soil through high-frequency vibration.

[0036] The mixing mechanism 20 is provided in pairs and symmetrically arranged on the left and right sides of the vibrating tube 101. The mixing mechanism 20 includes a side mounting strip 201, a mixing head 203 and a feeding pipe 206. The mixing head 203 is located at the lower end of the side mounting strip 201. The motor 107 drives the mixing head 203 to rotate at the lower end of the vibrating tube 101. The feeding pipe 206 delivers the curing agent between the left and right mixing heads 203. The soft soil and the curing agent are mixed by the rotating mixing head 203.

[0037] The switching mechanism 30 is located inside the vibrating tube 101 and includes a second motor 301. When the second motor 301 rotates forward, it drives the side mounting strip 201 to be tightly attached to the left and right sides of the vibrating tube 101. At this time, the device is in the stirring working mode. When the second motor 301 rotates in reverse, it drives the side mounting strip 201 to be flattened to the left and right sides of the vibrating tube 101. At this time, the device is in the vibration working mode.

[0038] In this embodiment, a mounting base 102 is fixed at the top end of the vibrating tube 101, and a mounting shaft 103 is coaxially arranged inside the vibrating tube 101. The mounting shaft 103 is rotatably connected to the vibrating tube 101 through a pair of bearing seats 104, and several eccentric blocks 105 are installed on the mounting shaft 103 at intervals. A friction wheel 106 is keyed to the bottom end of the mounting shaft 103. A motor 107 is set at the lower part of the vibrating tube 101 through a motor seat 108. The motor 107 is set vertically upward and a friction wheel 109 is keyed to its output end. The upper end face of the friction wheel 109 and the lower end face of the friction wheel 106 are in frictional engagement. When friction wheel 106 and friction wheel 2 109 are in frictional engagement, motor 107 drives the eccentric block 105 on mounting shaft 103 to rotate inside vibrating tube 101 after frictional transmission between friction wheel 106 and friction wheel 2 109, and causes vibrating tube 101 to generate high-frequency vibration. The high-frequency vibration of vibrating tube 101 vibrates the soft soil and discharges air bubbles in the soft soil.

[0039] In this embodiment, rectangular clearance openings 101a are symmetrically distributed on the upper part of the vibrating tube 101, and circular clearance openings 101b are symmetrically distributed on the lower part of the vibrating tube 101. The top end of the side mounting strip 201 is located at the clearance opening 101a and is rotatably connected to the vibrating tube 101 via a rotating shaft 202. The stirring head 203 is rotatably connected to the bottom end of the side mounting strip 201 via a stirring shaft 204. A friction wheel 205 is keyed to the inner end of the stirring shaft 204, and the outer circumferential surface of the friction wheel 205 is in frictional engagement with the lower end surface of the friction wheel 109. The feeding tube 206 has an L-shaped structure and is fixed to the front side of the vibrating tube 101 via several fixing seats 207. When friction wheel 2 109 and friction wheel 3 205 are in frictional engagement, motor 1 107 drives the stirring head 203 on the stirring shaft 204 to rotate at the lower end of the vibrating tube 101 after frictional transmission between friction wheel 2 109 and friction wheel 3 205. At the same time, the curing agent is delivered to the left and right stirring heads 203 through the feeding pipe 206, and the soft soil and curing agent are mixed by the rotating stirring head 203.

[0040] In this embodiment, the second motor 301 is mounted on the upper part of the vibrating tube 101 via the second motor base 302. The second motor 301 is vertically upward and its output end is connected to a lead screw 304 via a coupling 303. The lead screw 304 is connected to a sliding plate 306 via a lead screw nut 305, and the sliding plate 306 is slidably connected inside the vibrating tube 101. A U-shaped fixing frame 307 is centrally connected to the upper side of the sliding plate 306, and racks 308 are vertically connected to the left and right sides of the fixing frame 307. The rotating shaft 202 is keyed... A gear 309 is connected, and gears 309 and racks 308 on the same side mesh with each other. A sliding frame 310 is connected directly above the motor base 108, and several steel bar segments 311 are evenly connected between the sliding frame 310 and the motor base 108. The sliding frame 310 is slidably connected inside the vibrating tube 101. Several fixed pulleys 312 are evenly connected to the bottom surface of the mounting base 102. A steel wire rope 313 is threaded on each fixed pulley 312, and the two ends of the steel wire rope 313 are respectively connected to the sliding plate 306 and the sliding frame 310. The motor 301 rotates forward and drives the rack 308 to move upward. After transmission between the gear 309 and the rack 308, the side mounting strips 201 are driven to fit tightly against the left and right sides of the vibrating tube 101, and the friction wheels 205 on the left and right sides are driven to engage with the friction wheels 109. At this time, the device is in the mixing mode and is used to mix soft soil and solidifying agent. The motor 301 reverses and drives the rack 308 to move downward. After transmission between the gear 309 and the rack 308, the side strip 201 is flattened on the left and right sides of the vibrating tube 101. Under the traction of the wire rope 313, the friction wheel 109 and the friction wheel 106 are in frictional engagement. At this time, the device is in vibration mode and is used to expel air bubbles in the soft soil.

[0041] 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 at the end of the excavator's robotic arm.

[0042] In this embodiment, angle iron blocks 110 are symmetrically fixed to the lower part of the vibrating tube 101, and a compression spring 111 is connected between the angle iron blocks 110 and the motor base 108. The compression spring 111 can effectively support and automatically reset the motor 107 on the motor base 108.

[0043] In this embodiment, the mixing head 203 includes a mounting cylinder 2031. A spiral mounting strip 2032 is fixed to the outer circumferential surface of the mounting cylinder 2031, and several mounting plates 2033 are spaced apart on the mounting strip 2032. A mixing blade 2034 is vertically fixed to the side of each mounting plate 2033. A mounting disk 2035 is coaxially fixed to the outer end face of the mounting cylinder 2031, and a circular array of mixing strips 2036 is distributed on the outer end face of the mounting disk 2035. The mixing blades 2034 and the mixing strips 2036 thoroughly mix the soft soil and the solidifying agent.

[0044] In this embodiment, the vibrating tube 101 has a pair of guide strips 314 parallelly distributed on both the front and rear sides of the avoidance opening 101b, and a side baffle 315 is slidably connected between the pair of guide strips 314. Two steel bars 316 are vertically connected between the side baffle 315 and the sliding plate 306. When the device is in vibration working mode, the side baffle 315 is inserted into the inside of the exposed avoidance opening 101b to prevent soft soil and water from entering the vibrating tube 101 through the avoidance opening 101b, thereby preventing the contamination and damage of the mechanical parts by soft soil and water.

[0045] The working principle of this soft soil stabilization treatment device:

[0046] (1) Stirring working mode:

[0047] Motor 2 (301) rotates forward, driving rack 308 upward. Through transmission between gear 309 and rack 308, side strips 201 are pressed tightly against the left and right sides of vibrating tube 101. This causes friction wheels 3 (205) on both sides to engage with friction wheel 2 (109). At this time, the device is in mixing mode, used to mix soft soil and curing agent. When friction wheels 2 (109) and 3 (205) are engaged, motor 1 (107), through friction transmission between friction wheels 2 (109) and 3 (205), drives the mixing head 203 on mixing shaft 204 to rotate at the lower end of vibrating tube 101. Simultaneously, curing agent is delivered through feeding pipe 206 between the two mixing heads 203, and the rotating mixing heads 203 mix the soft soil and curing agent.

[0048] (2) Vibration working mode:

[0049] Motor 2 (301) reverses direction and drives rack 308 downward. After transmission between gear 309 and rack 308, side-mounted strip 201 flattens out on both sides of vibrating tube 101. Under the traction of wire rope 313, friction wheel 2 (109) and friction wheel 1 (106) engage in frictional contact. At this time, the device is in vibration mode and is used to expel air bubbles in soft soil. When friction wheel 1 (106) and friction wheel 2 (109) engage in frictional contact, motor 1 (107) drives eccentric block 105 on mounting shaft 103 to rotate inside vibrating tube 101 after frictional transmission between friction wheel 1 (106) and friction wheel 2 (109). This causes vibrating tube 101 to generate high-frequency vibration, which vibrates the soft soil and expels air bubbles, thereby reducing the porosity of the solidified soil and improving its durability and structural strength.

[0050] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
