TECHNICAL FIELD
[0001] The present application relates to the technical field of concrete construction, in particular to a marine concrete sediment removal device and efficient pouring process. BACKGROUND
[0002] When laying underwater bridge pile foundation, concrete needs to be injected into the conduit of the underwater bridge pile foundation. In order to ensure the effect of the grouting concrete during subsequent molding, the concrete injected into the underwater bridge pile foundation needs to be removed to ensure the cleanliness of the pile bottom, avoid the residue of mud or gravel weakening the pile end bearing capacity, and ensure the safety and long-term stability of the pile foundation structure, while optimizing the quality of concrete pouring and improving the service life and strength of the underwater bridge pile foundation after casting.
[0003] However, the sediment removal device has the following defects in actual use: 1. When the existing sediment removal device removes the concrete sediment at the bottom of the underwater bridge pile foundation, it generally uses a negative pressure extraction method to extend the pump nozzle to the inner bottom of the underwater bridge pile foundation to generate a negative pressure extraction force to extract the concrete sediment. However, when extracting the concrete sediment, the concrete at the bottom has been left for a period of time during actual operation, and the concrete at the top continuously presses the concrete at the bottom during grouting. The gap between the concrete sediments at the bottom is small, and the pump nozzle for extracting the concrete sediment is difficult to extend into the concrete sediment in blocks or even groups. Meanwhile, the large concrete sediments are easy to block the pump nozzle, the extraction pipeline connected to the pump nozzle, and the interior of the extraction pump, affecting the normal cleaning of the concrete sediment. 2. When the existing sediment removal device removes the concrete sediment, the concrete sediment is arranged at the bottom of the underwater bridge pile foundation, so the sediment removal device needs to be extended to the bottom of the bridge pile foundation by using a hanging rope suspension method. Therefore, the length of the hanging rope used in the conventional scheme is relatively long, and the amplitude of the sediment removal device at the bottom is difficult to control during operation, which is easy to collide with or even damage the inner wall of the conduit of the bridge pile foundation, and the safety is low.

[0028] With reference to the drawings Figure 5 The gear driving assembly 302 comprises a second driving source 3021 installed on the inner top of the fourth metal cylinder 208, a first gear 3022 connected to the output end of the second driving source 3021 and rotatably connected to the eccentric position of the inner top of the fourth metal cylinder 208, a second gear 3023 movably connected to the first gear 3022 and rotatably connected to the center of the inner top of the fourth metal cylinder 208, and a transfer rod 3024 movably connected to the inside of the metal outer shell 3011 and connected to the second gear 3023, wherein the top of the transfer rod 3024 is provided with a conical main gear 3025, and the side surface of the conical main gear 3025 is movably connected with a conical slave gear 3026.
[0029] In the present application, the side surface of the conical slave gear 3026 is provided with a horizontal rotating rod 30261 movably connected to the inside of the metal outer shell 3011, and the inside of the horizontal rotating rod 30261 is provided with a rotating block 30262 rotatably connected with a metal arm 303 extending to the outside.
[0030] In the present application, when the concrete sediment is treated, the second driving source 3021 is started to work, driving the first gear 3022 connected to the output end of the second driving source 3021 to rotate, and driving the second gear 3023 movably connected with the first gear 3022 to rotate. When the second gear 3023 rotates, the transfer rod 3024 movably connected to the side surface of the second gear 3023 rotates, on the one hand driving the conical main gear 3025 to rotate, and on the other hand driving the metal outer shell 3011 to rotate.
[0031] When the metal outer shell 3011 rotates, the stirring blades 3013 movably connected to the outside of the metal outer shell 3011 rotate, stirring the concrete sediment to move.
[0032] When the conical main gear 3025 rotates, the side surface of the connected conical from gear 3026 will rotate and drive the horizontal rotating rod 30261 connected with the conical from gear 3026 to rotate. When the horizontal rotating rod 30261 rotates, the side surface of the connected rotating block 30262 will rotate, so that the metal arm 303 connected to the eccentric position of the rotating block 30262 moves.

At this time, the elastic force of the second spring 3062 will buffer and protect the collision force and impact force, ensuring the vibrating effect on the concrete sediment and improving the effect of removing the concrete sediment.
[0037] Embodiment two Please refer to Figures 1-11 , a high-efficiency pouring process for marine concrete, comprising the following steps: S1, mixing of concrete: before the opening of the test personnel must determine the sand, stone moisture content, the theoretical mix of concrete into the construction mix, check the quality of sand and gravel, verify the use of raw materials and mix ratio notification single whether consistent, sufficient quantity to pour a pile and at least 10% of the amount of surplus, while checking the mixing machine and pouring each process equipment operation; S2, the first batch of concrete pouring quantity calculation: the first batch of concrete should meet the needs of the initial depth of the pipe and the gap between the bottom of the pipe, the first batch of concrete volume is: , wherein V is the first batch of concrete required volume, D is the diameter of the pile hole, H1 is the distance between the bottom of the pile hole and the bottom of the pipe, 0.3m, H2 is the initial depth of the pipe, 1.0m, d is the inner diameter of the pipe, 38.2cm, h1 is the height of the concrete column in the pile hole when the concrete reaches the depth of the pipe ; S3, underwater concrete pouring: according to the calculation results of the first batch of pouring, equipped with a large hopper, normal feeding small hopper, when the bottom is sealed, the large hopper and the tank are used simultaneously, the crawler crane is used to lift the large hopper, the water ball is placed in the pipe before pouring the concrete, the water ball is cut off when pouring the concrete to pour the underwater concrete, the concrete is poured continuously to ensure that the whole pile is poured before the concrete initial setting, and the normal pouring of concrete can be carried out after the first sealing is successful; S4, concrete sediment removal: after the completion of the concrete pouring, the concrete sediment after the completion of the pouring is removed to reduce the content of the concrete internal sediment, ensure the fluidity of the concrete and improve the effect of the concrete pouring.
[0038] Example three For S3 underwater concrete pouring: 1, after the second hole cleaning, immediately start pouring underwater concrete, and use crawler crane to remove the pipe during concrete pouring; 2, the pouring time of underwater concrete should not exceed the initial setting time of the first batch of concrete; 3, the initial storage quantity must be sufficient, and it is strictly forbidden to pour into the hole when the initial storage quantity is insufficient. After confirming that the initial storage quantity is sufficient, the hopper baffle can be lifted, and the first batch of concrete can be poured. At the same time, observe the hole return slurry, measure the pipe depth, and check whether there is water in the pipe; 4. After the initial pouring of concrete is completed, install the pouring hopper and compactly and continuously pour the concrete. Do not stop pouring midway. During the pouring process, frequently use the sounding weight to detect the rising height of the concrete surface and timely raise and remove the guide pipe to maintain the proper depth of the guide pipe. The elevation of the concrete surface should be measured by the sounding weight at multiple points and should be checked by the calculated value of the amount of concrete poured. The depth of the guide pipe should not be less than 2 m, but the maximum depth should not exceed 9 m, and is generally controlled to be 4-6 m. Before each time the guide pipe is raised, the height of the concrete surface should be detected. In special cases, the number of detection times should be increased in the gravel soil layer and the pouring speed should be slowed down, and the return slurry should be observed to correctly analyze and determine the conditions in the hole; 5. When the guide pipe is raised, the axis should be kept vertical and the position should be kept centered, and the guide pipe should be raised step by step. If the guide pipe joint is hung on the reinforcement cage, the guide pipe can be rotated to be separated from the reinforcement and then moved to the center of the hole; 6. During the pouring process, the concrete mixture should be prevented from overflowing from the top of the hopper or falling into the hole from the outside of the hopper, so that the mud contains cement and becomes thick and coagulated, causing inaccurate detection; 7. As the concrete in the hole rises, the guide pipe should be removed step by step. When the guide pipe is raised, the axis should be kept vertical and the position should be kept centered, and the guide pipe should be raised step by step; 8. The action of removing the guide pipe should be fast, and the time should not exceed 15 minutes. The bolts, rubber pads and tools should be prevented from falling into the hole. The removed pipe sections should be immediately cleaned and neatly stacked; 9. During the pouring of concrete, the concrete test blocks should be made according to the requirements of the specification, and the workability and slump of the concrete should be detected at any time; 10. Measures should be taken to prevent the reinforcement cage from floating during pouring: when the top surface of the poured concrete is about 1 m from the bottom of the reinforcement cage, the pouring speed should be reduced; when the top surface of the concrete rises to more than 4 m above the bottom of the cage, the guide pipe should be raised so that the bottom opening is higher than the bottom of the cage by more than 2 m, and then the pouring speed should be restored; 11. After the concrete has initially set, use a special sounding weight to check whether the acoustic pipe is blocked. If it is blocked, use a high-pressure water pump to flush the acoustic pipe to ensure that the acoustic pipe is smooth and not blocked; 12. When the concrete is poured to within 5 m of the upper part of the pile, the guide pipe is not raised, and the guide pipe is removed once the pouring is completed to the specified elevation. When the last section of the guide pipe is pulled out, it is slowly pulled out and shaken up and down to prevent the pile from being jammed with mud or forming a void.
[0039] Example Four Notes for Underwater Concrete Pouring 1. Before pouring the concrete, complete the inspection and certification of the concealed engineering construction, and carefully fill in the construction record table and the concrete pouring record during the construction process.
[0040] 2. The concrete pouring work is continuous and uninterrupted. If the concrete pouring is interrupted, the pipe is lifted slightly according to the buried depth of the pipe, and the fault is removed immediately.
[0041] 3. The water-proof ball must be inspected.
[0042] 4. The pile foundation sounding pipe is prevented from being damaged during construction.
[0043] 5. The concrete pouring is a complete, continuous and uninterrupted work. Before the pouring work starts, the mechanical management personnel and the responsible driver repair and maintain all the machines used for the concrete pouring to ensure the normal operation of the machines during the construction.
[0044] 6. The foreign matters are prevented from falling into the pipe during the pouring. If necessary, a square partition grid with a spacing of 150 mm is arranged in the middle of the storage hopper.
[0045] 7. The concrete pouring work is a key process of the pile foundation construction, and a person is arranged to be responsible for the command and coordination.
[0046] 8. After the underwater concrete pouring is completed, the equipment used for the mixing, transportation and pouring of the concrete is counted and cleaned, and is properly stored for standby.
