Description

Technical Field

[0001] This utility model belongs to the field of vibratory compaction test technology for sandy soil foundations without filler, and particularly relates to a vibratory compaction test device for foundation treatment in coastal sandy soil areas without filler. Background Technology

[0002] In foundation treatment in coastal sandy areas, the vibratory compaction test without filler is an important means to verify the applicability of the technology, optimize construction parameters, and evaluate the reinforcement effect. Coastal sandy areas are mostly composed of medium-coarse sand, fine sand, or dredged sand. The vibratory compaction method without filler rearranges sand particles through vibration and high-pressure water jetting to achieve a compaction effect.

[0003] Existing vibratory compaction test devices for foundation treatment in coastal sandy areas have long processing times and high energy consumption at a single point, making them unsuitable for special geological conditions such as coral sand and marine sedimentary sand. Utility Model Content

[0004] This invention provides a vibratory compaction test device for foundation treatment in coastal sandy areas, aiming to solve the problems mentioned in the background art regarding the long single-point processing time and high energy consumption of existing vibratory compaction test devices for foundation treatment in coastal sandy areas, which are not suitable for special geological conditions such as coral sand and marine sedimentary sand.

[0005] To solve the above problems, this utility model is implemented as follows: a vibratory compaction test device for foundation treatment in coastal sandy soil areas without filler, comprising: a tracked vehicle for moving the vibratory compaction test device; a steel frame installed on the tracked vehicle; a hoist installed on the tracked vehicle; a guide wheel installed on the steel frame; a steel wire rope disposed on the hoist and connected to the guide wheel; and a vibratory compaction mechanism installed at one end of the steel wire rope for performing the vibratory compaction test.

[0006] Preferably, the vibratory impact mechanism includes: a vibratory rod installed at one end of the wire rope; a vibratory head fixedly installed at the bottom end of the vibratory rod; a spiral vent hole opened on the vibratory head; a double eccentric block differential frequency exciter installed on the inner wall of the vibratory head; and a salinity sensor and a pH probe disposed on the vibratory head.

[0007] Preferably, a seawater-grade air compressor is installed at the top of the vibrating rod, and the pressure of the seawater-grade air compressor is 0.6-1.0 MPa.

[0008] Preferably, a connecting seat is fixedly installed on the vibrating rod, the connecting seat has a slot, and the inner wall of the slot has an installation groove.

[0009] Preferably, one end of the wire rope is fixedly installed with a plug, and the plug is adapted to the slot.

[0010] Preferably, the mounting groove is provided with a locking mechanism, the locking mechanism comprising: a pin slidably mounted on the inner wall of the mounting groove; a sleeve plate fixedly sleeved on the pin; a spring slidably sleeved on the pin; and a pull ring fixedly mounted on one end of the pin.

[0011] Preferably, the insert block has a pin hole that is adapted to the pin rod.

[0012] Preferably, a positioning hole is provided on one inner wall of the slot, and the positioning hole is adapted to the pin.

[0013] Compared with related technologies, the non-filler vibratory compaction test device for foundation treatment in coastal sandy soil areas provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, the vibratory compaction testing device for foundation treatment in coastal sandy soil areas provided in this solution consists of a tracked vehicle, a steel frame, a hoist, guide wheels, wire ropes, and a vibratory compaction mechanism. The tracked vehicle is used to move the entire vibratory compaction testing device, facilitating transfer to different test locations. The steel frame is mounted on the tracked vehicle, providing support for the guide wheels. The hoist is also mounted on the tracked vehicle and connected to the guide wheels mounted on the steel frame via wire ropes. The guide wheels change the direction of the wire rope, allowing the hoist to manipulate the wire rope more flexibly. The vibratory compaction mechanism is mounted at one end of the wire rope. Through the cooperation of the hoist and the wire rope, the vibratory compaction mechanism can be precisely placed in the designated position for vibratory compaction testing. The device has a reasonable overall structure, and all components work together, improving the flexibility and convenience of vibratory compaction testing, and helping to conduct more efficient and accurate tests in coastal sandy soil areas. This vibratory compaction test for foundation treatment uses a 316L stainless steel shell for the vibrating head, with a built-in double eccentric block differential frequency exciter (vertical 30Hz / horizontal 8Hz). The vibrating rod has a hollow design and is equipped with a seawater-grade air compressor (0.6-1.0MPa). Real-time air exhaust is achieved through the central channel of the vibrating rod to liquefy the sand. The bottom of the device integrates a salinity sensor and a pH probe, and the data is transmitted to the ground control console via a waterproof cable. The innovation lies in the fact that, through vibration-pneumatic coupling, the relative density of the dredged sand can be increased from 55% to over 72% without the need for adding crushed stone filler. The corrosion-resistant structural design extends the device's lifespan by 3 times in coastal environments with chloride ion content >5%. Compared with traditional vibratory compaction equipment, this device reduces the single-point processing time to 15 minutes and energy consumption by 40%, making it particularly suitable for special geological conditions such as coral sand and marine sedimentary sand.

[0022] In this embodiment, the vibratory compaction test device for foundation treatment in coastal sandy soil areas consists of a tracked vehicle 1, a steel frame 2, a hoist 3, guide wheels 4, a steel wire rope 5, and a vibratory compaction mechanism. The tracked vehicle 1 is used to move the entire vibratory compaction test device, facilitating transfer to different test locations. The steel frame 2 is mounted on the tracked vehicle 1, providing support for the guide wheels 4. The hoist 3 is also mounted on the tracked vehicle 1 and connected to the guide wheels 4 mounted on the steel frame 2 via the steel wire rope 5. The guide wheels 4 change the direction of the steel wire rope 5, allowing the hoist 3 to manipulate the steel wire rope 5 more flexibly. The vibratory compaction mechanism is mounted at one end of the steel wire rope 5. Through the cooperation of the hoist 3 and the steel wire rope 5, the vibratory compaction mechanism can be accurately placed in the designated position for vibratory compaction testing. The device has a reasonable overall structure, and the components work together to improve the flexibility and convenience of vibratory compaction testing, which helps to more efficiently and accurately conduct tests in coastal sandy soil areas. A vibratory compaction test without filler was conducted for foundation treatment. The vibratory head 7 has a 316L stainless steel shell and a built-in double eccentric block differential frequency exciter 9 (vertical 30Hz / horizontal 8Hz). The vibratory rod has a hollow design and is equipped with a seawater-grade air compressor 12 (0.6-1.0MPa). Real-time air exhaust is achieved through the central channel of the vibratory rod 6 to liquefy the sand. The bottom of the device integrates a salinity sensor 10 and a pH probe 11. Data is transmitted to the ground control console via a waterproof cable. The innovation lies in the fact that, through vibration-pneumatic coupling, the relative density of the dredged sand is increased from 55% to over 72% without the need for adding crushed stone filler. The corrosion-resistant structural design extends the device's lifespan by 3 times in coastal environments with chloride ion content >5%.
