Description

Technical Field

[0001] The invention belongs to the technical field of gravel pile construction, in particular to a sunken tube structure for gravel pile construction. Background Art

[0002] Gravel piles are a type of composite foundation reinforcement pile made of crushed stone or pebbles as the main material. The soil in the river channel is soaked in water for a long time, and has a high porosity, high compressibility, and thixotropy and rheological characteristics. Gravel piles are often used to process the foundation in this soil, and the construction of gravel piles usually adopts the sunken tube method.

[0003] The main construction steps of the pipe sinking method are to first measure and place the pile position. After the measurement is completed, the gravel pile machine is arranged at the predetermined position. Then the pile pipe with the closed petal pile tip is vertically inserted into the soil. After the pile pipe reaches the designed depth, sand and gravel are poured into the hollow pile pipe. After the pouring is completed, the petal pile tip is opened and the pipe is pulled out at a uniform speed so that the sand and gravel inside the pile pipe falls into the pile pit. After the entire pipe is pulled out, the construction of the gravel pile is completed.

[0004] In the process of using the pipe sinking method to construct gravel piles, it is necessary to first determine the position of the pile pipe of the gravel pile machine. Once the position is determined, the position of the pile pipe cannot be adjusted. When the position of the pile pipe deviates from the predetermined position and the pile pipe needs to be fine-tuned, the entire machine needs to be adjusted, which can easily cause unnecessary waste of manpower and affect the progress of construction.

When it is necessary to fine-tune the position of the pipe pile 14, the electric push rod installed on the side wall of the sliding block 11 can be controlled, so that the two electric push rods push the first push rod 12, and then push the adjustment block 13, so that the position of the pipe pile 14 can be fine-tuned. After the adjustment is completed, the winch inside the winch cover 6 can be controlled to release the adjustment cable 7, so that the pipe pile 14 is lowered, and a pile pit is dug inside the soil under the action of the vibrator 141. After excavation reaches the rated depth, the excavation is stopped, and pebbles or gravel are injected into the interior of the pipe pile 14 through the injection assembly. Then the petal pile tip 15 is opened and intermittently adjusted by the winch. The pipe pile 14 is lifted, so that the gravel inside the pipe pile 14 falls into the pile pit, thereby completing the construction of the gravel pile. The first push rod 12 is pushed or pulled by the electric push rod, thereby adjusting the position of the adjustment block 13, so that the position of the pipe pile 14 can be fine-tuned. This structural design realizes the function of adjusting the position of the pipe pile 14 without adjusting the position of the gravel pile machine body 1. It effectively solves the problem that the position of the pipe pile 14 cannot be adjusted after the position of the gravel pile machine body 1 is determined. When using the electric push cylinder, an electric push cylinder with sufficient thrust to push the adjustment block 13 can be selected. At the same time, an electric push cylinder with a brake function is required to prevent the adjustment block 13 from being offset again after the adjustment is completed.

[0032] like Figures 2 to 4 As shown, the injection assembly includes a storage hopper 16; the storage hopper 16 is arranged above the sliding frame 10, and a support rod 161 is fixed between the top of the sliding frame 10; a feed port is opened at the position of the internal sinking pile 14 of the adjusting block 13; the internal rotation of the adjusting block 13 is connected to a blocking plate 131; the blocking plate 131 is arranged at a position corresponding to the feed port of the adjusting block 13; the rotation of the blocking plate 131 is driven by a driving motor; an electric push cylinder is installed at the bottom of the support block 9, and the output end of the electric push cylinder is fixedly connected to a second push rod 18; the end of the second push rod 18 is fixedly connected to a sealing block 19; the sealing block 19 is arranged at the position corresponding to the discharge port of the storage hopper 16; the storage hopper 16 and the feed port on the top of the adjusting block 13 are fixedly connected with an injection pipe 17; during operation, when it is necessary to inject stones such as gravel or pebbles into the interior of the immersed tube pile 14, the stones can be first put into the storage hopper 16, and when it is necessary to put the stones into the interior of the immersed tube pile 14, the second push rod 18 and the sealing block 19 can be pulled by the electric push cylinder to open the feed port at the bottom of the storage hopper 16, and at the same time, the driving motor can be controlled to drive the blocking plate 131 to rotate, so that the feed port of the adjusting block 13 is opened, so that the stones can be put into the interior of the immersed tube pile 14, which makes the injection of stones more convenient.

[0033] like Figures 4 to 6 As shown, a pressurized fan 20 is installed on the top of the support block 9; the output end of the pressurized fan 20 is fixedly connected to an air guide pipe 21; the air guide pipe 21 passes through the outer wall of the storage hopper 16 and enters the discharge port position of the storage hopper 16; the end of the air guide pipe 21 is arranged at a position corresponding to the bottom of the sealing block 19; during operation, after the stone is injected into the interior of the pipe pile 14, the electric push cylinder can be controlled to push the second push rod 18 and the sealing block 19 to close the discharge port of the storage hopper 16, so that the top of the pipe pile 14 is sealed. When the stone inside the pipe pile 14 is blocked, the pressurized fan 20 can be driven to pressurize the top of the pipe pile 14 through the air guide pipe 21, so that the pressure inside the pipe pile 14 is greater, so that the stone inside the pipe pile 14 can be better released from the pipe pile 14, effectively avoiding the blockage of the stone inside the pipe pile 14.

[0034] like Figures 6 and 7 As shown, a dust cover 22 is fixed to the top of the support block 9; the dust cover 22 is arranged at the top position of the pressurizing fan 20; a dust screen 23 is provided at the position of the dust cover 22 corresponding to the air inlet end of the pressurizing fan 20; when working, by providing a dust screen 23 on the outer cover of the pressurizing fan 20, the pressurizing fan 20 can be effectively prevented from being damaged by being hit, and at the same time, a dust screen 23 is provided on the side wall of the dust cover 22, which can effectively prevent the dust cover 22 from blocking the air inlet end of the pressurizing fan 20.

[0035] like Figure 7 As shown, a plurality of connecting ropes 24 are fixedly connected to the outer wall of the dust cover 22; the ends of the connecting ropes 24 are fixedly connected to knocking balls 25; the knocking balls 25 are arranged at positions corresponding to the dust screen 23; during operation, when the outside air is drawn into the interior of the dust cover 22, the dust screen 23 will block the dust, gravel and other impurities from the outside, and when the air flows into the interior of the dust cover 22, the air will drive the knocking balls 25 to shake and knock on the surface of the dust screen 23, so that the impurities blocking the outside of the dust screen 23 can be knocked off, making the surface of the dust screen 23 cleaner.

[0036] like Figure 5 As shown, a rubber sealing ring 26 is fixed to the bottom of the sealing block 19; the rubber sealing ring 26 is arranged at a position corresponding to the discharge port of the storage hopper 16; during operation, when the second push rod 18 slides downward and closes the discharge port of the storage hopper 16 through the sealing block 19, the rubber sealing ring 26 can scrape off the stones remaining on the side wall of the discharge port of the storage hopper 16, and at the same time make the sealing between the sealing block 19 and the discharge port of the storage hopper 16 better, and when the booster fan 20 increases the pressure to the inside of the pipe pile 14, leakage between the sealing block 19 and the storage hopper 16 is effectively avoided.

[0037] like Figure 3 As shown, a positioning rod 27 is provided inside the sliding frame 10; the two ends of the positioning rod 27 are respectively fixed to the side walls of the two opposite sliding blocks 11; a positioning hole is opened inside the adjusting block 13; the positioning hole and the positioning rod 27 are arranged correspondingly; the positioning rod 27 is arranged parallel to the first push rod 12; during operation, when the electric push rod pushes the adjusting block 13, the positioning rod 27 restricts the adjusting block 13, so that the positioning rod 27 is less likely to tilt during the sliding process, thereby making the sliding of the adjusting block 13 more stable. At the same time, the positioning rod 27 can assist the first push rod 12 in supporting the adjusting block 13, making the adjusting block 13 more stable.

[0038] like Figure 6 As shown, a plurality of counterweight blocks 28 are provided on the top of the support block 9; the counterweight blocks 28 are arranged at positions corresponding to the pressurized fan 20 and the dust cover 22; during operation, by arranging the counterweight blocks 28 on the top of the support block 9, the support block 9 can be balanced, so that the support block 9 can be better maintained stable.

[0039] like Figure 8 As shown, the interior of the fixing bolt 903 is slidably connected to a sliding plate 29; a spring is fixed between the top of the sliding plate 29 and the inner side wall of the fixing bolt 903; the bottom of the sliding plate 29 is fixedly connected to a connecting rod 30; the other end of the connecting rod 30 is fixedly connected to a contact block 31; during operation, when the fixing sleeve 902 is fixed by the fixing bolt 903, when the fixing bolt 903 is screwed into the inside of the threaded hole, the contact block 31 will first contact the bottom of the threaded hole, and then continue to screw in the fixing bolt 903, so that the sliding plate 29 can squeeze the spring, and then the sliding plate 29 is pushed by the elastic force of the spring, which can make the friction between the thread on the surface of the fixing bolt 903 and the thread inside the threaded hole greater, so that the fixing effect of the fixing bolt 903 on the fixing sleeve 902 can be better.

[0040] like Figure 8 As shown, a plurality of balls 32 are snap-fitted and connected to the bottom side wall of the contact block 31; the balls 32 are regularly arranged in a circular array on the bottom surface of the contact block 31; during operation, when the fixing bolt 903 is screwed into the threaded hole, the balls 32 can convert the sliding friction between the contact block 31 and the bottom of the threaded hole into rolling friction, thereby reducing the wear between the contact block 31 and the bottom of the threaded hole.

[0041] During operation, when it is necessary to construct a gravel pile, the gravel pile machine body 1 can be moved to the pile point position to be constructed. When it is necessary to fine-tune the position of the pipe pile 14, the electric push rod installed on the side wall of the sliding block 11 can be controlled, so that the two electric push rods push the first push rod 12, and then push the adjustment block 13, so that the position of the pipe pile 14 can be fine-tuned. After the adjustment is completed, the winch inside the winch cover 6 can be controlled to release the adjustment cable 7, so that the pipe pile 14 is lowered, and a pile pit is dug inside the soil under the action of the vibrator 141. After excavation reaches the rated depth, the excavation is stopped, and pebbles or gravel are injected into the interior of the pipe pile 14 through the injection assembly. Then the petal pile tip 15 is opened and intermittently adjusted by the winch. The pipe pile 14 is lifted so that the gravel inside the pipe pile 14 falls into the pile pit, thereby completing the construction of the gravel pile. The first push rod 12 is pushed or pulled by the electric push rod, and then the position of the adjustment block 13 is adjusted, so that the position of the pipe pile 14 can be fine-tuned. The structural design realizes the function of adjusting the position of the pipe pile 14 without adjusting the position of the gravel pile body 1, and effectively solves the problem that the position of the pipe pile 14 cannot be adjusted after the position of the gravel pile body 1 is determined. When using the electric push cylinder, an electric push cylinder with sufficient thrust to push the adjustment block 13 can be selected. At the same time, an electric push cylinder with a braking function is required to avoid the adjustment block 13 from being displaced again after the adjustment is completed.

[0042] When it is necessary to inject gravel, pebbles or other stones into the interior of the immersed tube pile 14, the stones can be first put into the storage hopper 16. When it is necessary to put the stones into the interior of the immersed tube pile 14, the second push rod 18 and the sealing block 19 can be pulled by the electric push cylinder to open the feed port at the bottom of the storage hopper 16. At the same time, the drive motor can be controlled to drive the blocking plate 131 to rotate, so that the feed port of the adjustment block 13 is opened, so that the stones can be put into the interior of the immersed tube pile 14, which makes it more convenient to inject the stones.

[0043] After the stone is injected into the interior of the pipe pile 14, the electric push cylinder can be controlled to push the second push rod 18 and the sealing block 19 to close the discharge port of the storage hopper 16, so that the top of the pipe pile 14 is sealed. When the stone inside the pipe pile 14 is blocked, the pressurized fan 20 can be driven to pressurize the top of the pipe pile 14 through the air guide pipe 21, so that the pressure inside the pipe pile 14 is greater, so that the stone inside the pipe pile 14 can be better released from the pipe pile 14, effectively avoiding the blockage of the stone inside the pipe pile 14.

[0044] By installing a dust screen 23 on the outer cover of the pressurizing fan 20, the pressurizing fan 20 can be effectively prevented from being damaged by impact. At the same time, a dust screen 23 is opened on the side wall of the dust cover 22, which can effectively prevent the dust cover 22 from blocking the air inlet end of the pressurizing fan 20.

[0045] When outside air is drawn into the interior of the dust cover 22, the dust screen 23 will block impurities such as dust and gravel from the outside. When the air flows into the interior of the dust cover 22, the air will drive the knocking ball 25 to shake and knock on the surface of the dust screen 23, thereby knocking off the impurities blocking the outside of the dust screen 23, making the surface of the dust screen 23 cleaner.

[0046] When the second push rod 18 slides downward and closes the discharge port of the storage hopper 16 through the sealing block 19, the rubber sealing ring 26 can scrape off the stones remaining on the side wall of the discharge port of the storage hopper 16, and at the same time make the sealing between the sealing block 19 and the discharge port of the storage hopper 16 better. When the booster fan 20 increases the pressure inside the pipe pile 14, leakage between the sealing block 19 and the storage hopper 16 is effectively avoided.

[0047] When the electric push rod pushes the adjustment block 13, the positioning rod 27 restricts the adjustment block 13, so that the positioning rod 27 is less likely to tilt during the sliding process, thereby making the sliding of the adjustment block 13 more stable. At the same time, the positioning rod 27 can assist the first push rod 12 to support the adjustment block 13, making the adjustment block 13 more stable.

[0048] By arranging a counterweight block 28 on the top of the support block 9, the support block 9 can be balanced so that the support block 9 can be kept more stable.

[0049] When the fixing sleeve 902 is fixed by the fixing bolt 903, when the fixing bolt 903 is screwed into the inside of the threaded hole, the contact block 31 will first contact the bottom of the threaded hole, and then continue to screw in the fixing bolt 903, so that the sliding plate 29 can squeeze the spring, and then the sliding plate 29 is pushed by the elastic force of the spring, which can make the friction between the thread on the surface of the fixing bolt 903 and the thread inside the threaded hole greater, so that the fixing bolt 903 can better fix the fixing sleeve 902.

[0050] When the fixing bolt 903 is screwed into the threaded hole, the ball 32 can convert the sliding friction between the contact block 31 and the bottom of the threaded hole into rolling friction, thereby reducing the wear between the contact block 31 and the bottom of the threaded hole.
