Description

Technical Field

[0001] This invention relates to the field of underwater foundation construction technology, and more specifically to an underwater foundation reinforcement device. Background Technology

[0002] Vibro-compaction is a commonly used foundation treatment method. Its basic principle is as follows: when reinforcing loose sand foundations, repeated vibration of a vibro-compactor and the action of water flushing cause instantaneous structural damage to the surrounding soil within a certain radial range, reducing its shear strength. This allows soil particles to rearrange, increasing their relative density and forming piles with greater strength than the surrounding soil. These piles then combine with the original foundation soil to form a composite foundation, thereby improving the overall strength of the foundation. Compared with traditional foundation treatment processes, vibro-compaction has many advantages, including simpler construction and better foundation reinforcement results.

[0003] Currently, the construction method for underwater vibratory compactors mostly involves using a crane ship to lift one or two vibratory compactors for underwater vibratory compaction of foundations. Compared to the construction of large underwater foundation beds, this construction method can only vibrate one or two points at a time, resulting in very low construction efficiency, large labor input, and high economic costs. Furthermore, the preparation period for each vibratory compaction point change is long, which further reduces the overall construction efficiency, and the multiple point changes also have a significant impact on the construction quality. Summary of the Invention

[0004] To address the problems of the prior art, the present invention provides an underwater foundation reinforcement device that can be equipped with multiple vibratory compactors for simultaneous construction operations, and can achieve simultaneous positioning of multiple vibratory compactors in a single positioning operation.

[0005] The objective of this invention can be achieved through the following technical solution: an underwater foundation reinforcement device, comprising a steel frame and columns, wherein the columns are installed on the lower end of the steel frame for support, and several sets of walking mechanisms are installed on the steel frame, wherein the tracks of all the walking mechanisms are arranged in parallel, and several fixing mechanisms are installed on each of the walking mechanisms, wherein the steel rod at the upper end of the vibratory compactor is installed on the fixing mechanism.

[0006] Preferably, the fixing mechanism includes a load-bearing frame, a support plate, a fixing frame, a steel ball, and a buffer mechanism. The load-bearing frame is square and installed on the traveling mechanism. The support plate is placed on the load-bearing frame. The buffer mechanism is installed between the load-bearing frame and the support plate to buffer the horizontal movement of the support plate. The fixing frame is embedded in the support plate. The steel ball is embedded in the fixing frame and rotated. The steel rod is slidably inserted into the steel ball.

[0007] Preferably, the surface of the steel ball is covered with a sliding layer. The sliding layer is made of GM high-density fiberboard.

[0008] Preferably, a sliding plate is laid on the end face of the load-bearing frame, and the support plate is placed on the sliding plate. The sliding plate is made of GM high-density fiberboard.

[0009] Preferably, a surrounding plate is installed on the outside of the load-bearing frame, and the buffer mechanism includes multiple connecting plates and multiple springs. The connecting plates are installed around the support plate, one end of the spring is fixed on the connecting plate, and the other end of the spring is fixed on the surrounding plate.

[0010] Preferably, the traveling mechanism includes two parallel crossbeams and a rack and pinion track. The two ends of the crossbeams are mounted on the steel frame, the rack and pinion track is mounted on the crossbeams, and the load-bearing frame travels on the rack and pinion track.

[0011] In use, the vibratory compactor is installed at the lower end of the steel pole. The traveling mechanism is started according to the preset vibratory compaction points, and the position of each vibratory compactor is adjusted. The crane lifts the steel frame and vibratory compactor underwater and fixes them in place. The vibratory compactor is started and sinks into the sand layer. The construction operation and construction quality are controlled according to the vibratory compaction process requirements. After the construction is completed, the vibratory compactor is turned off, the steel frame and vibratory compactor are hoisted and moved to the next set of vibratory compaction positions, and then the construction operation is repeated.

[0012] The advantages of this invention include: Underwater foundation vibratory compaction allows for the simultaneous operation of multiple vibratory compactors, precise control of the relative positions of compaction points, and simultaneous positioning of multiple compactors in a single setup. This significantly reduces preparation time, minimizes construction quality issues caused by positioning, and reduces rework and resource waste. Furthermore, the device is reusable, simple in structure, and easy to operate, reducing labor input, improving construction efficiency and quality, and thus increasing economic value. In addition, the invention's walking mechanism allows for convenient adjustment of the relative positions of each vibratory compactor to adapt to different compaction points; a single positioning allows for the common positioning of multiple vibratory compactors; and the buffer mechanism effectively avoids the adverse effects of vibration between multiple compactors, enabling simultaneous operation of multiple vibratory compactors, ensuring construction quality, and greatly improving work efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] An underwater foundation reinforcement device includes a steel frame 1 and a column 2. The column 2 is installed on the lower end of the steel frame 1 for support. Several sets of walking mechanisms 3 are installed on the steel frame 1. The tracks of all the walking mechanisms 3 are arranged in parallel. Several fixing mechanisms are installed on each of the walking mechanisms 3. The steel rod 9 at the upper end of the vibratory impactor is installed on the fixing mechanism.

[0023] Furthermore, in this embodiment, the fixing mechanism includes a load-bearing frame 4, a support plate 5, a fixing frame 6, a steel ball 7, and a buffer mechanism 8. The load-bearing frame 4 is square and mounted on the traveling mechanism 3. The support plate 5 is placed on the load-bearing frame 4. The buffer mechanism 8 is installed between the load-bearing frame 4 and the support plate 5 to buffer the horizontal movement of the support plate 5. The fixing frame 6 is embedded in the support plate 5. The steel ball 7 is embedded in the fixing frame 6 and rotated. The steel rod 9 is slidably inserted into the steel ball 7. A sliding plate layer 10 is wrapped around the surface of the steel ball 7. The sliding plate layer 10 is made of GM high-density fiberboard. A sliding plate 11 is laid on the end face of the load-bearing frame 4, and the support plate 5 is placed on the sliding plate 11. The sliding plate 11 is also made of GM high-density fiberboard.

[0024] Furthermore, in this embodiment, a surrounding plate 12 is installed on the outside of the load-bearing frame 4. The buffer mechanism 8 includes multiple connecting plates 81 and multiple springs 82. The connecting plates 81 are installed around the support plate 5. One end of the spring 82 is fixed to the connecting plate 81, and the other end of the spring 82 is fixed to the surrounding plate 12.

[0025] The steel rod 9 is inserted into the steel ball 7, and the steel ball 7 is mounted in the fixed frame 6 with a ball hinge. This satisfies the vibration effect of the vibratory impactor during vibration. At the same time, a spring 82 is installed between the support plate 5 and the surrounding plate 12 to buffer the vibration of the vibratory impactor during operation, preventing the vibration of a single vibratory impactor from affecting the entire steel frame 1, so that each vibratory impactor becomes an independent working unit and does not interfere with each other.

[0026] Furthermore, in this embodiment, the walking mechanism 3 includes two parallel crossbeams 31 and a rack and pinion track. The two ends of the crossbeams 31 are mounted on the steel frame 1, and the rack and pinion track is mounted on the crossbeams 31. The load-bearing frame 4 travels on the rack and pinion track.

The rack and pinion track typically includes a track 32 with racks mounted on it, a walking wheel 33 with external teeth, and a motor 34. The motor 34 drives the walking wheel 33 to travel along the track.

[0027] In this embodiment of the invention, the vibratory compactor is installed at the lower end of the steel rod 9. The traveling mechanism 3 is started according to the preset vibratory compaction points to adjust the position of each vibratory compactor. The crane lifts the steel frame 1 and the vibratory compactor into the water and fixes them in place. The vibratory compactor is started to sink into the sand layer. The construction operation and construction quality are controlled according to the vibratory compaction process requirements. After the construction is completed, the vibratory compactor is turned off, the steel frame 1 and the vibratory compactor are lifted and moved to the next set of vibratory compaction positions, and then the construction operation is repeated.

[0028] The advantages of this invention include: Underwater foundation vibratory compaction allows for the simultaneous operation of multiple vibratory compactors, precise control of the relative positions of compaction points, and simultaneous positioning of multiple compactors in a single setup. This significantly reduces preparation time, minimizes construction quality issues caused by positioning, and reduces rework and resource waste. Furthermore, the device is reusable, simple in structure, and easy to operate, reducing labor input, improving construction efficiency and quality, and thus increasing economic value. In addition, the traveling mechanism 3 allows for convenient adjustment of the relative positions of each vibratory compactor to adapt to different compaction points; a single positioning operation enables the common positioning of multiple vibratory compactors; and the buffer mechanism 8 effectively avoids the adverse effects of vibration between multiple vibratory compactors, allowing for simultaneous operation of multiple compactors, ensuring construction quality, and greatly improving work efficiency.
