Description

Technical Field

[0001] The present invention relates to the technical field of concrete pile reinforcement, and specifically provides a device for underwater partial reinforcement of concrete piles. Background Art

[0002] In various underwater construction projects, concrete piles, as 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 underwater environment, during the long-term use of concrete piles, they are often affected by various factors such as water flow scouring, chemical erosion, and biological attachment, resulting in diseases such as damage, cracks, and reduced strength of the pile body. These diseases not only affect the bearing capacity of the concrete piles but may also cause the instability and failure of the entire structure. Therefore, it is particularly important to perform partial reinforcement on underwater concrete piles. For the partial reinforcement of underwater concrete piles, there are already various methods in the prior art. Among them, using a fiberglass sleeve for underwater partial repair of concrete piles is a relatively effective technical means. The basic construction process of this technology is as follows: First, roughen the surface of the test pile to increase the adhesion between the fiberglass sleeve and the concrete pile; then, prefabricate the fiberglass sleeve and pour a certain proportion of grouting material into the sleeve; then, wrap the fiberglass sleeve around the concrete pile to be repaired and temporarily fix it with a fastening band; subsequently, inject epoxy glue into the locking groove of the sleeve to ensure the sealing between the sleeve and the concrete pile; finally, fix the sleeve joints with stainless steel screws at certain intervals to complete the installation of the fiberglass sleeve. After pouring cement soil into the fiberglass sleeve, a rubber hammer needs to be used to hammer the fiberglass sleeve. The main purpose of this step is to promote the flow of the concrete in the fiberglass sleeve, make it more compact, thereby improving the direct tensile bond strength between the grouting material and the concrete, and ensuring the repair effect. By hammering, the air bubbles and voids in the grouting material can be eliminated, and it can be more evenly distributed between the fiberglass sleeve and the concrete pile, forming a tight bonding layer. However, there are still some problems in the implementation of the prior art. Since the fiberglass sleeve is located underwater, when manually using a rubber hammer to hammer it, not only is the hammering difficult, but also under the resistance of water, the hammering difficulty will be further increased. At the same time, due to the inability to accurately control the hammering force on the fiberglass sleeve, it may result in too large or too small hammering force. Too large a hammering force may cause damage to the fiberglass sleeve, affecting the repair effect; too small a hammering force will not achieve the purpose of promoting the flow and compaction of the concrete.

[0013] A local underwater reinforcement device for concrete piles proposed by the present invention has the beneficial effects as follows: 1. By holding this device and diving into the water, align the right end of the rubber knocking column with the position of the glass fiber sleeve that needs to be knocked, and keep an appropriate distance from the glass fiber sleeve. Start the first driving component, and use the first driving component to drive the gear disc to rotate. The rotation of the gear disc can drive the slide plate to rotate around the gear disc through the slide rail, so that the connecting rod can be driven by the slide plate to perform a circumferential motion. The cooperation between the circumferential motion connecting rod and the connecting rod can pull the push block to perform a reciprocating left and right motion. Thus, the cooperation between the push block and the first guide rod can drive the rubber knocking column to perform a reciprocating left and right motion, so that the glass fiber sleeve can be knocked and vibrated by the reciprocating left and right motion of the rubber knocking column, promoting the flow of the concrete in the glass fiber sleeve and making it more compact.

[0014] 2. When the rubber knocking column moves to the right, it will be affected by the water resistance, thus reducing the knocking force of the rubber knocking column. When the rubber knocking column moves to the right, under the action of the water resistance, it will push the rubber knocking column to move to the left, so that the extrusion block can extrude the pressure sensor. Thus, the water resistance applied 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 increases the power of the first driving component according to the water resistance applied to the rubber knocking column, so as to ensure that the knocking force applied by the rubber knocking column to the glass fiber sleeve is constant.

[0015] 3. When the rubber knocking column moves to the right to knock on the glass fiber sleeve, it will cause the probe to first contact the outer wall of the glass fiber sleeve. As the rubber knocking column moves to the right, the glass fiber sleeve will block the probe, causing the probe to slide into the inner cavity of the rubber knocking column and compress the second spring to deform elastically until the probe contacts the resistive touch sensor. The resistive touch sensor senses the extrusion 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 position of the connecting rod is adjusted according to the length of the probe extending from the right end of the rubber knocking column and the remaining stroke of the rubber knocking column moving to the right. The second driving component is activated, and the driving block is driven to move back and forth by the second driving component. Then, the driving rod is driven to move back and forth by the driving block through the rotating plate. The cooperation between the driving groove and the driving column can cause the sleeve to drive the first gear to rotate. The rotation of the first gear can cooperate with the rack to cause the sliding plate to drive the connecting rod to move left and right, thereby adjusting the stroke of the rubber knocking column so that the right end of the rubber knocking column can just contact the outer wall of the glass fiber sleeve to knock on the glass fiber sleeve.

[0016] 4. This device can accurately control the knocking force, avoiding damage to the glass fiber sleeve due to excessive force or failure to achieve the purpose of promoting the flow and filling of concrete due to insufficient force. It can effectively eliminate air bubbles and voids in the grouting material, make the grouting material more evenly distributed between the glass fiber sleeve and the concrete pile, improve the direct 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 a more reliable guarantee for the local reinforcement of underwater concrete piles.

[0028] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0029] When it is necessary to strike the fiberglass sleeve, the staff holds this device and dives underwater, and dives to an appropriate position. Align the right end of the rubber striking column 10 with the position of the fiberglass sleeve that needs to be struck. Start the second motor 520. The output end of the second motor 520 drives 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 around the toothed disc 52 through the slide rail 53. The rotation of the sleeve 56 around the toothed disc 52 can drive the rotating plate 513 to rotate through the driving rod 511, so as to promote the rotating plate 513 to rotate along the outer wall of the driving block 515. The rotation of the slide plate 54 around the toothed disc 52 can drive the connecting rod 59 to move circumferentially. Thus, the cooperation between the circumferentially moving connecting rod 59 and the connecting rod 510 can pull the push block 6 to move left and right reciprocally. Furthermore, the first guide rod 12 can be used to drive the rubber striking column 10 to move left and right reciprocally. When the rubber striking column 10 moves to the right, due to the resistance exerted by the water on it, the rubber striking column 10 will be prompted to move to the left. Thus, the extrusion block 11 can be used to squeeze the pressure sensor 8. The pressure sensor 8 can be used to detect the resistance exerted by the water on the rubber striking column 10. And the pressure sensor 8 transmits the signal to the intelligent adaptive motor controller 4. The intelligent adaptive motor controller 4 adjusts the power of the second motor 520 according to the water resistance, so as to ensure that the striking force exerted by the rubber striking column 10 on the fiberglass sleeve is constant. Since the staff is in a floating state in the water, it is very difficult to hold this device steadily. Furthermore, as the rubber striking column 10 moves to the right, the probe 94 will first contact the outer wall of the fiberglass sleeve. The outer wall of the fiberglass sleeve blocks the probe 94. As the rubber striking column 10 moves to the right, the probe 94 will be squeezed to move into 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 transmits the 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 position of the connecting rod 59 is adjusted according to the length of the probe 94 extending from the right end of the rubber striking column 10 and the remaining stroke of the rubber striking column 10 moving to the right at this time. Start the first motor 517. The output end of the first motor 517 can 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. Thus, the driving block 515 drives the driving rod 511 to move forward or backward through the rotating plate 513. Thus, 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. Furthermore, the stroke of the rubber striking column 10 can be adjusted.The right end of the rubber knocking post 10 can just contact the outer wall of the glass fiber sleeve, so as to knock the glass fiber sleeve. Repeating the above actions can achieve the knocking vibration of the glass fiber sleeve, promote the flow of the concrete in the glass fiber sleeve, and make it more compact.

[0030] In summary, this device can accurately control the knocking force, avoid damaging the glass fiber sleeve due to excessive force or failing to achieve the purpose of promoting the flow and compaction of the concrete due to insufficient force. It can effectively eliminate the bubbles and voids in the grouting material, make the grouting material more evenly distributed between the glass fiber sleeve and the concrete pile, improve the direct 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 a more reliable guarantee for the local reinforcement of underwater concrete piles.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
