Description

Technical Field

[0001] This invention relates to the field of dredging engineering technology, specifically an environmentally friendly underwater DCM breaking and excavation construction process and device. Background Technology

[0002] DCM piles are pile structures formed by forcibly mixing sand, cement, and other solidifying agents. This type of pile structure has good stability and can remain in water for a long time.

[0003] In order to ensure the quality of the concrete piles, the height of the piles is usually made higher than the predetermined height when making DCM piles. However, in the construction of the subsea tunnel foundation trench, it is necessary to remove the extra piles. Therefore, an environmentally friendly underwater DCM removal and excavation construction process and device are proposed to address the above problems. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and solve at least one of the above-mentioned problems, this invention proposes an environmentally friendly underwater DCM breaking and excavation construction process and device.

[0005] The technical solution adopted by this invention to solve its technical problem is: an environmentally friendly underwater DCM breaking and excavation construction process, which includes the following steps: S1: The construction vessel is driven to the water surface of the area to be excavated and demolished, the construction vessel is fixed with anchor cables, and the movement of the grab bucket is controlled through the control room on the construction vessel. S2: Lower the grab bucket to the DCM pile head, and control the construction vessel to move forward, backward, left and right in a directional and quantitative manner by controlling the release and retraction of the anchor cable, and excavate the excavation points in sequence. S3: After the DCM pile head demolition and excavation within the working range of the crane is completed, the construction vessel will be moved to the next area for demolition and excavation.

[0006] An environmentally friendly underwater DCM demolition and excavation construction device is disclosed. This device is suitable for the aforementioned underwater DCM demolition and excavation construction process. A power distribution cabinet is installed in the control room. The power distribution cabinet is mounted on top of a base. Heat dissipation holes are provided on both sides of the power distribution cabinet, and filter screens are fixedly connected to the openings of the heat dissipation holes. During operation, the heat dissipation holes on both sides of the power distribution cabinet are used to dissipate heat from the internal components. The filter screens prevent dust from entering the power distribution cabinet through the heat dissipation holes, thus avoiding damage to the internal components.

[0007] Preferably, a support plate is fixedly connected to one side of the top of the base; a motor is fixedly connected to the support plate on the side near the distribution cabinet; a first rod is fixedly connected to the output shaft of the motor, and circular plates are sleeved and fixedly connected to both ends of the first rod. A gear ring is fixedly connected to one side of the circular plate, and a first gear is sleeved and fixedly connected to the outer wall of the first rod; the first gear is located inside the gear ring; a support block is fixedly connected to the top of the distribution cabinet; a second rod is rotatably connected through the support block, a second gear is fixedly connected to one end of the second rod, and a strip plate is fixedly connected to the other end. Brush bristles are fixedly connected to the strip plate on the side near the distribution cabinet; only a portion of the teeth are provided on the outer periphery of the first gear. The inner wall of the gear ring only has partial gear teeth. During operation, to prevent dust from clogging the filter screen, the motor can be started, causing the motor to rotate the first rod, which in turn rotates the circular plate and the gear ring. When the gear ring meshes with the second gear, the second gear will cause the second rod to rotate forward, causing the second rod to rotate slightly with the strip plate and brush bristles, thus cleaning the dust on the surface of the filter screen. When the first gear meshes with the second gear, the ring gear will cause the second rod to rotate in the opposite direction, causing the second rod to rotate slightly with the strip plate and brush bristles, thus cleaning the dust on the surface of the filter screen, preventing dust from clogging the filter screen, and ensuring normal heat dissipation of the power distribution cabinet.

[0008] Preferably, the strip plate has a cavity 1 inside, and the strip plate has multiple through holes on the side near the distribution cabinet; a shell is fixed to the outer wall of the distribution cabinet; a No. 3 rod is slidably connected through the shell on the side near the strip plate, one end of the No. 3 rod is fixed to a No. 1 plate, and the other end is fixed to a No. 2 plate; the No. 2 plate is slidably connected inside the shell; a No. 1 airbag is provided inside the shell; the No. 1 airbag and the cavity 1 are connected by a hose; a No. 1 one-way valve is provided inside the hose; during operation, initially, the strip plate squeezes the No. 1 plate, causing the No. 2 plate to squeeze the No. 1 airbag, and the No. 1 airbag is in a compressed state. When the No. 2 gear drives the No. 2 rod to rotate, the strip plate will move away from the No. 1 plate, and the No. 1 airbag will gradually return to its original state, and air will be drawn in through the hose. The through holes are directly opposite the filter screen, which can draw the dust generated from cleaning the filter screen into the cavity 1 and the No. 1 airbag. Because a one-way valve is provided inside the hose, the gas will not flow back from the hose into the cavity 1.

[0009] Preferably, an exhaust pipe is fixedly connected to the bottom of the first airbag, and a second one-way valve is installed inside the exhaust pipe; the bottom of the housing is sealed by a cover plate; during operation, when the strip plate squeezes the first plate, the second plate will squeeze the first airbag, causing the gas inside the first airbag to be discharged from the exhaust pipe; when it is necessary to clean the dust inside the housing, simply open the cover plate to allow the dust inside the housing to be discharged from the bottom of the housing.

[0010] Preferably, the bottom of the strip plate is open; a T-shaped plate is slidably connected to the bottom of the strip plate, and rubber blocks are fixed to the sidewalls of the T-shaped plate that contact the inner wall of the cavity; the inner wall of the cavity is provided with dust-adhesive paper; during operation, the dust-adhesive paper is a transparent adhesive tape that adsorbs dust through its adhesiveness; the bottom of the strip plate is sealed by the T-shaped plate, and the rubber blocks improve the sealing performance between the T-shaped plate and the inner wall of the cavity.

[0011] Preferably, the gas flow direction of the first one-way valve is from the cavity to the first airbag; the gas flow direction of the second one-way valve is from the first airbag to the outside; during operation, when the second plate squeezes the first airbag, the gas inside the first airbag is discharged from the exhaust pipe, and when the second plate does not squeeze the first airbag, the first airbag absorbs gas from the outside through the hose.

[0012] Preferably, the base has a second cavity inside; a fourth rod is slidably connected through the bottom of the base, a third plate is fixedly connected to the bottom end of the fourth rod, and a fourth plate is fixedly connected to the top end of the fourth rod; springs are fixedly connected between the fourth plate and the top and bottom of the second cavity; a slider is slidably connected to the top of the second cavity; a connecting rod is hinged to the top of the fourth plate, and the other end of the connecting rod is hinged to the bottom of the slider; during operation, when the construction vessel experiences significant vibration, the bottom of the base will slide along the fourth rod, causing the spring to be compressed and stretched. When the fourth plate moves downward, it will compress the connecting rod, causing the connecting rod to push the slider to slide at the top of the second cavity. When the fourth plate moves downward, it will cause the connecting rod to push the slider to move in the opposite direction, which has a good shock absorption effect and avoids the phenomenon of loose wiring caused by long-term significant vibration of the distribution cabinet.

[0013] The advantages of this invention are: 1. In this invention, the first rod is rotated by a motor, which causes the second gear to drive the second rod to swing back and forth. This causes the second rod to drive the strip plate and brush bristles to swing slightly, thereby cleaning the dust on the surface of the filter screen. This prevents dust from clogging the filter screen and ensures normal heat dissipation of the power distribution cabinet.

[0014] 2. In this invention, when the construction vessel experiences significant vibration, the bottom of the base slides along rod number four, causing the spring to be compressed and stretched. When plate number four moves up and down, the connecting rod pushes the slider to slide at the top of cavity number two, which has a good shock absorption effect. This prevents the wiring of the power distribution cabinet from becoming loose due to long-term significant vibration, and ensures the normal power supply to the electrical equipment on the construction vessel.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Example 1 Please see Figure 1 As shown, an environmentally friendly underwater DCM (Discharge Management Center) excavation and demolition construction process includes the following steps: S1: The construction vessel is driven to the water surface of the area to be excavated and demolished, the construction vessel is fixed with anchor cables, and the movement of the grab bucket is controlled through the control room on the construction vessel. S2: Lower the grab bucket to the DCM pile head, and control the construction vessel to move forward, backward, left and right in a directional and quantitative manner by controlling the release and retraction of the anchor cable, and excavate the excavation points in sequence. S3: After the DCM pile head demolition and excavation within the working range of the crane is completed, the construction vessel will be moved to the next area for demolition and excavation.

[0020] The control room on the construction vessel plays a regulatory role in the entire construction process. The power distribution cabinet in the control room is used to supply power to various components on the construction vessel, ensuring the normal operation of the entire power system. By cleaning the dust from the heat dissipation holes of the power distribution cabinet, it is possible to prevent dust from entering the inside of the power distribution cabinet through the heat dissipation holes and causing damage to the internal components.

[0021] Example 2 Please see Figure 2-7 As shown, an environmentally friendly underwater DCM demolition and excavation construction device is provided. This device is suitable for the above-mentioned underwater DCM demolition and excavation construction process. The control room is equipped with a power distribution cabinet 1. The power distribution cabinet 1 is installed on the top of the base 2. The power distribution cabinet 1 has heat dissipation holes on both sides, and a filter screen 3 is fixed to the opening of the heat dissipation hole. During operation, the heat dissipation holes on the left and right sides of the power distribution cabinet 1 are used to dissipate heat from the internal components of the power distribution cabinet 1. The filter screen 3 can prevent dust from entering the inside of the power distribution cabinet 1 through the heat dissipation holes, which would cause damage to the internal components of the power distribution cabinet 1.

[0022] In one embodiment of the present invention, a support plate 4 is fixedly connected to one side of the top of the base 2; a motor 5 is fixedly connected to the support plate 4 on the side near the distribution cabinet 1; a first rod 6 is fixedly connected to the output shaft of the motor 5; circular plates 7 are sleeved and fixedly connected to both ends of the first rod 6; a gear ring 8 is fixedly connected to one side of the circular plate 7; a first gear 9 is also sleeved and fixedly connected to the outer wall of the first rod 6; the first gear 9 is located inside the gear ring 8; a support block 10 is fixedly connected to the top of the distribution cabinet 1; a second rod 11 is rotatably connected through the support block 10; a second gear 12 is fixedly connected to one end of the second rod 11, and a strip plate 13 is fixedly connected to the other end; bristles 14 are fixedly connected to the strip plate 13 on the side near the distribution cabinet 1; only a few bristles are provided on the outer periphery of the first gear 9. The inner wall of the gear ring 8 also has only a portion of the gear teeth. During operation, to prevent dust from clogging the filter screen 3, the motor 5 can be started, causing the motor 5 to drive the first rod 6 to rotate, which in turn drives the circular plate 7 and the gear ring 8 to rotate. When the gear ring 8 meshes with the second gear 12, the second gear 12 will drive the second rod 11 to rotate in the forward direction, causing the second rod 11 to drive the strip plate 13 and the brush bristles 14 to rotate slightly, thus cleaning the dust on the surface of the filter screen 3. When the first gear 9 meshes with the second gear 12, the first gear will drive the second rod 11 to rotate in the reverse direction, causing the second rod 11 to drive the strip plate 13 and the brush bristles 14 to rotate slightly, thus cleaning the dust on the surface of the filter screen 3, preventing dust from clogging the filter screen 3, and ensuring normal heat dissipation of the power distribution cabinet 1.

[0023] In one embodiment of the present invention, the strip plate 13 has a cavity inside, and the strip plate 13 has multiple through holes 15 on the side near the distribution cabinet 1; a housing 16 is fixedly connected to the outer wall of the distribution cabinet 1; a third rod 17 is slidably connected through the housing 16 on the side near the strip plate 13, one end of the third rod 17 is fixedly connected to a first plate 18, and the other end is fixedly connected to a second plate 19; the second plate 19 is slidably connected inside the housing 16; a first airbag 20 is provided inside the housing 16; the first airbag 20 is connected to the cavity through a hose 21; The hose 21 is equipped with a first check valve. During operation, initially, the strip plate 13 squeezes the first plate 18, causing the second plate 19 to squeeze the first airbag 20, which is in a compressed state. When the second gear 12 drives the second rod 11 to rotate, the strip plate 13 will move away from the first plate 18, and the first airbag 20 will gradually return to its original state, allowing air to be drawn in through the hose 21. The through hole 15 is directly opposite the filter screen 3, which can draw in the dust generated during cleaning of the filter screen 3 into the cavity and the first airbag 20. Because the hose 21 is equipped with a check valve, the gas will not flow back from the hose 21 into the cavity.

[0024] In one embodiment of the present invention, an exhaust pipe 22 is fixedly connected to the bottom of the first airbag 20, and a second one-way valve is provided inside the exhaust pipe 22; the bottom of the housing 16 is sealed by a cover plate 23; during operation, when the strip plate 13 presses the first plate 18, the second plate 19 will press the first airbag 20, causing the gas inside the first airbag 20 to be discharged from the exhaust pipe 22; when it is necessary to clean the dust inside the housing 16, it is only necessary to open the cover plate 23 to allow the dust inside the housing 16 to be discharged from the bottom of the housing 16.

[0025] In one embodiment of the present invention, the bottom of the strip plate 13 is open; a T-shaped plate 24 is slidably connected to the bottom of the strip plate 13, and rubber blocks 25 are fixedly attached to the sidewalls of the T-shaped plate 24 that contact the inner wall of the cavity; a dust-adhesive paper 26 is provided on the inner wall of the cavity; during operation, the dust-adhesive paper 26 is a transparent adhesive tape, which adsorbs dust through its adhesiveness; the bottom of the strip plate 13 is sealed by the T-shaped plate 24, and the rubber blocks 25 improve the sealing performance between the T-shaped plate 24 and the inner wall of the cavity.

[0026] In one embodiment of the present invention, the gas flow direction of the first one-way valve is from the cavity to the first airbag 20; the gas flow direction of the second one-way valve is from the first airbag 20 to the outside; during operation, when the second plate 19 squeezes the first airbag 20, the gas inside the first airbag 20 is discharged from the exhaust pipe 22; when the second plate 19 does not squeeze the first airbag 20, the first airbag 20 absorbs gas from the outside through the hose 21.

[0027] In one embodiment of the present invention, a second cavity is provided inside the base 2; a fourth rod 27 is slidably connected through the bottom of the base 2, a third plate 28 is fixedly connected to the bottom end of the fourth rod 27, and a fourth plate 29 is fixedly connected to the top end of the fourth rod 27; springs 30 are fixedly connected between the fourth plate 29 and the top and bottom of the second cavity; a slider 31 is slidably connected to the top of the second cavity; a connecting rod 32 is hinged to the top of the fourth plate 29, and the other end of the connecting rod 32 is hinged to the slider. At the bottom of 31; during operation, when the construction vessel experiences significant vibration, the bottom of base 2 will slide along rod 27, causing spring 30 to be compressed and stretched. When plate 29 moves downward, it will press connecting rod 32, causing connecting rod 32 to push slider 31 to slide at the top of cavity 2. When plate 29 moves downward, connecting rod 32 will push slider 31 to move in the opposite direction, which has a good shock absorption effect and avoids the phenomenon of loose wiring caused by long-term significant vibration in distribution cabinet 1.

[0028] Working principle: To prevent dust from clogging the filter screen 3, the motor 5 can be started, causing the first rod 6 to rotate. The first rod 6 then rotates the circular plate 7 and the gear ring 8. When the gear ring 8 meshes with the second gear 12, the second gear 12 will cause the second rod 11 to rotate in the forward direction, causing the second rod 11 to rotate the strip plate 13 and the brush bristles 14 slightly, thus cleaning the dust on the surface of the filter screen 3. When the first gear 9 meshes with the second gear 12, the first gear will cause the second rod 11 to rotate in the reverse direction, causing the second rod 11 to rotate the strip plate 13 and the brush bristles 14 slightly, thus cleaning the dust on the surface of the filter screen 3, preventing dust from clogging the filter screen 3, and ensuring the normal heat dissipation of the power distribution cabinet 1. Initially, the strip plate 13 presses against the first plate 18, causing the second plate 19 to press against the first airbag 20, which is in a compressed state. When the second gear 12 drives the second rod 11 to rotate, the strip plate 13 will move away from the first plate 18, causing the first airbag 20 to gradually return to its original state. Air will be drawn in through the hose 21, and the through hole 15 is directly opposite the filter screen 3, which can draw the dust generated from cleaning the filter screen 3 into the cavity and the first airbag 20. When the strip plate 13 presses against the first plate 18, the second plate 19 will press against the first airbag 20, causing the gas inside the first airbag 20 to be discharged from the exhaust pipe 22. When it is necessary to clean the dust inside the housing 16, simply open the cover plate 23 to allow the dust inside the housing 16 to be discharged from the bottom of the housing 16. When the construction vessel experiences significant vibration, the bottom of base 2 will slide along rod 27, causing spring 30 to be compressed and stretched. When plate 29 moves downward, it will press connecting rod 32, causing connecting rod 32 to push slider 31 to slide at the top of cavity 2. When plate 29 moves downward, connecting rod 32 will push slider 31 to move in the opposite direction, which has a good shock absorption effect and prevents the wiring of distribution cabinet 1 from becoming loose due to long-term significant vibration.
