Description

Technical Field

[0001] The invention relates to the technical field of concrete pile reinforcement, in particular to a local underwater reinforcement device for concrete piles. Background Art

[0002] In various underwater construction projects, concrete piles are important structural support components. The stability and reliability of their performance are directly related to the safety and service life of the entire project. However, due to the special characteristics of the underwater environment, concrete piles are often affected by various factors such as water erosion, chemical corrosion, and biological adhesion during long-term use, resulting in damage, cracks, and strength reduction in the pile body. These damages not only affect the bearing capacity of the concrete piles, but may also cause instability and destruction of the entire structure. Therefore, local reinforcement of underwater concrete piles is particularly important.

[0003] There are many methods for local reinforcement of underwater concrete piles in the existing technology. Among them, using fiberglass sleeves for underwater local repair of concrete piles is a relatively effective technical means. The basic construction process of this technology is as follows: first, the surface of the test pile is roughened to increase the bonding strength between the fiberglass sleeve and the concrete pile; then, the fiberglass sleeve is prefabricated and a certain proportion of grouting material is poured into the sleeve; then, the fiberglass sleeve is wrapped around the concrete pile to be repaired and temporarily fixed with a fastening tape; then, epoxy glue is injected into the locking groove of the sleeve to ensure the sealing between the sleeve and the concrete pile; finally, the sleeve joints are fixed with stainless steel screws at regular intervals to complete the installation of the fiberglass sleeve;

[0004] After pouring cement soil into the fiberglass casing, it is necessary to use a rubber hammer to hammer the fiberglass casing. The main purpose of this step is to promote the flow of concrete in the fiberglass casing and make it more substantial, thereby improving the positive tensile bond strength between the grouting material and the concrete and ensuring the repair effect. By hammering, bubbles and voids in the grouting material can be eliminated, making it more evenly distributed between the fiberglass casing and the concrete pile, forming a tight bonding layer;

[0005] However, there are still some problems in the implementation of the existing technology. Since the fiberglass casing is located underwater, it is not only difficult to hammer it manually with a rubber hammer, but the resistance of the water will further increase the difficulty of hammering. At the same time, since it is impossible to accurately control the hammering force on the fiberglass casing, the hammering force may be too large or too small. Excessive hammering force may cause damage to the fiberglass casing and affect the repair effect; if the hammering force is too small, the purpose of promoting the flow and filling of concrete cannot be achieved.

[0016] The present invention proposes a device for local underwater reinforcement of concrete piles, which has the following beneficial effects:

[0017] 1. The present invention dives into the water by holding the device, aligns the right end of the rubber knocking column with the position of the fiberglass casing that needs to be knocked, and keeps an appropriate distance from the fiberglass casing, starts the first driving component, and uses the first driving component to drive the gear disc to rotate. The rotation of the gear disc can drive the slide plate to rotate with the gear disc as the center through the slide rail, so that the slide plate can drive the connecting rod to move circumferentially, and the cooperation between the connecting rod and the connecting rod that move circumferentially can pull the push block to move back and forth, so that the cooperation between the push block and the first guide rod can drive the rubber knocking column to move back and forth, so that the rubber knocking column that reciprocates left and right can be used to knock and vibrate the fiberglass casing, thereby promoting the flow of concrete in the fiberglass casing and making it more substantial.

[0018] 2. According to the present invention, when the rubber knocking column moves to the right, it will be affected by the resistance of water, thereby reducing the knocking force of the rubber knocking column. When the rubber knocking column moves to the right, the water resistance will push the rubber knocking column to move to the left, so that the extrusion block can be used to squeeze the pressure sensor, so that the resistance applied by water to the rubber knocking column can be detected by the pressure sensor, and the signal is transmitted to the intelligent adaptive motor controller through the pressure sensor. The intelligent adaptive motor controller is used to increase the power of the first drive component according to the resistance applied by water to the rubber knocking column, thereby ensuring that the knocking force applied by the rubber knocking column to the fiberglass casing is constant.

[0019] 3. When the rubber knocking column moves to the right to knock the glass fiber sleeve, the probe will first come into contact with the outer wall of the glass fiber sleeve. As the rubber knocking column moves to the right, the glass fiber sleeve will be used to block the probe, thereby forcing the probe to slide toward the inner cavity of the rubber knocking column and squeeze the second spring to elastically deform until the probe contacts the resistive touch sensor. The resistive touch sensor senses the squeezing of the probe. Since the length of the probe is fixed and the distance between the probe and the resistive touch sensor is fixed, the probe extends out of the right end of the rubber knocking column and the The rubber knocking column moves the remaining stroke to the right to adjust the position of the connecting rod, and the second driving assembly is started. The second driving assembly is used to drive the driving block to move back and forth, and the driving block is used to drive the driving rod to move back and forth through the rotating plate. The cooperation between the driving groove and the driving column can prompt the sleeve to drive the first gear to rotate. The rotation of the first gear can cooperate with the rack to prompt the slide to drive the connecting rod to move left and right, and then the stroke of the rubber knocking column can be adjusted, so that the right end of the rubber knocking column can just contact the outer wall of the fiberglass sleeve, thereby knocking the fiberglass sleeve.

[0020] 4. This device can accurately control the force of the knock to avoid excessive force that damages the fiberglass casing or too little force that fails to achieve the purpose of promoting the flow and filling of concrete. It can effectively eliminate bubbles and gaps in the grouting material, make the grouting material more evenly distributed between the fiberglass casing and the concrete pile, improve the positive tensile bond strength between the grouting material and the concrete, ensure the repair effect, reduce the construction difficulty and risk, improve the construction efficiency and quality, and provide more reliable protection for the local reinforcement of underwater concrete piles.

[0043] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0044] When it is necessary to knock on the fiberglass casing, the staff dives underwater with the device in hand and dives into a suitable position, aligns the right end of the rubber knocking column 10 with the position where the fiberglass casing needs to be knocked, starts the second motor 520, and uses the output end of the second motor 520 to drive the second gear 522 to rotate through the rotating rod 521. The rotation of the second gear 522 can drive the toothed disc 52 to rotate. The rotation of the toothed disc 52 can drive the slide plate 54 and the sleeve 56 to rotate with the toothed disc 52 as the center through the slide rail 53. The rotation of the sleeve 56 with the toothed disc 52 as the center can drive the rotating plate 513 to rotate through the driving rod 511, thereby prompting the rotating plate 513 to rotate along the outer wall of the driving block 515, and the slide plate 54 rotates with the toothed disc 52 as the center. The connecting rod 59 is driven to move circumferentially, so that the cooperation between the circumferentially moving connecting rod 59 and the connecting rod 510 can pull the push block 6 to move back and forth, and then the first guide rod 12 can be used to drive the rubber knocking column 10 to move back and forth. When the rubber knocking column 10 moves to the right, the resistance exerted by the water on it will cause the rubber knocking column 10 to move to the left, so that the squeezing block 11 can be used to squeeze the pressure sensor 8, and the pressure sensor 8 can be used to detect the resistance exerted by the water on the rubber knocking column 10, and the pressure sensor 8 transmits the signal to the intelligent adaptive motor controller 4, and the intelligent adaptive motor controller 4 is used to adjust the power of the second motor 520 according to the resistance of the water, thereby ensuring that the rubber knocking column 1 The striking force applied to the glass fiber sleeve is constant. Since the staff is in a floating state in the water, it is difficult to hold the device steadily. As the rubber striking column 10 moves to the right, the probe 94 is first prompted to contact the outer wall of the glass fiber sleeve, and the outer wall of the glass fiber sleeve is used to block the probe 94. As the rubber striking column 10 moves to the right, the probe 94 is squeezed to move toward the inner cavity of the rubber striking column 10 until the probe 94 contacts the resistive touch sensor 93. The resistive touch sensor 93 senses the probe 94, and the resistive touch sensor 93 transmits a signal to the first motor 517. Since the length of the probe 94 is fixed and the distance between the probe 94 and the resistive touch sensor 93 is fixed, the probe 94 extends according to the current state. The length of the right end of the rubber knocking column 10 and the remaining stroke of the rubber knocking column 10 moving to the right are used to adjust the position of the connecting rod 59, and the first motor 517 is started. The output end of the first motor 517 can be used to drive the screw 516 to rotate. The rotational force generated by the rotation of the screw 516 can prompt the driving block 515 to move forward or backward, so that the driving block 515 can drive the driving rod 511 to move forward or backward through the rotating plate 513, so that the cooperation between the driving groove 512 and the driving column 57 can prompt the sleeve 56 to drive the first gear 58 to rotate. The rotation of the first gear 58 can cooperate with the rack 55 to prompt the slide plate 54 to drive the connecting rod 59 to move left or right, thereby adjusting the stroke of the rubber knocking column 10.The right end of the rubber knocking column 10 can just come into contact with the outer wall of the fiberglass sleeve, thereby knocking the fiberglass sleeve. Repeating the above action can achieve knocking vibration on the fiberglass sleeve, prompting the concrete in the fiberglass sleeve to flow and make it more substantial.

[0045] In summary, this device can accurately control the knocking force to avoid excessive force that damages the fiberglass casing or too little force that fails to achieve the purpose of promoting the flow and filling of concrete. It can effectively eliminate bubbles and gaps in the grouting material, make the grouting material more evenly distributed between the fiberglass casing and the concrete pile, improve the positive tensile bonding strength between the grouting material and the concrete, ensure the repair effect, reduce the construction difficulty and risk, improve the construction efficiency and quality, and provide more reliable protection for the local reinforcement of underwater concrete piles.
