Description

Technical Field

[0001] This utility model relates to a slope protection technology, and more particularly to an equipment technology for the maintenance and construction of deep-water wharves, specifically a pin controller for connecting piles and engineering piles in underwater revetment construction of wharves. Background Technology

[0002] As is well known, during the construction of various cargo terminals, in order to prevent the loss of underwater sand and soil, a row of piles is driven around the terminal for sand and soil protection. Initially, the driven piles are sufficient to protect the underwater sand and soil. Figure 1 As shown. However, with long-term transportation operations, the sand at the bottom of the wharf is gradually carried away, reducing the amount of sand. This leads to a significant reduction in the depth of the engineering piles driven into the ground during construction, affecting the stability of the engineering piles. The stability of the engineering piles will affect the stability and safety of the wharf, which may cause the wharf to collapse and be scrapped, resulting in serious economic losses and damage to equipment and personnel.

[0003] Currently, with the increasing service life of wharves and the lack of corresponding maintenance measures, the safety of wharf foundations is becoming increasingly serious, necessitating appropriate measures. However, due to the greater depth of deep-water wharves, directly driving engineering piles into the foundation would increase construction difficulty and reduce efficiency. Therefore, using transition piles as intermediate piles to drive engineering piles into the underwater foundation is an effective method. To save costs, after pile driving, the transition piles must be separated from the engineering piles and reused. Therefore, it is required that the transition piles and engineering piles be both easy to connect and easy to separate. However, since the separation work is carried out underwater, conventional electric welding and cutting presents problems such as harsh working environment, inconvenience in operation, and safety issues, which must be addressed. Utility Model Content

[0004] The purpose of this invention is to address the problem of inconvenience in connecting and separating the measure piles and engineering piles during the reinforcement of existing old wharf revetment pile foundations, and to design a pin controller for connecting measure piles and engineering piles for underwater wharf revetment construction.

[0005] The technical solution of this utility model is:

[0006] A pin controller for connecting subgrade piles and engineering piles in underwater revetment construction of a wharf includes a pin 1. The pin 1 is inserted into a pin hole 9 on an inner steel sleeve 5. The pin 1 is connected to the piston rod of a hydraulic cylinder 2. The hydraulic cylinder 2 is mounted on a fixed plate 4, which is connected to a reinforcing steel plate 3. The reinforcing steel plate 3 is mounted on an inner circular plate 6. A hydraulic control system is mounted on the inner circular plate 6. One end of the inner steel sleeve 5 is fixedly installed in the subgrade pile 8, and the other end extends out of the subgrade pile 8. The pin hole 9 is located at the end of the inner steel sleeve 5 extending out of the subgrade pile 8.

[0007] The number of the pins 1 and the hydraulic cylinders 2 that control their extension and retraction is at least 3, and they are evenly arranged around the inner steel sleeve 5.

[0008] The number of the pins 1 and the hydraulic cylinders 2 that control their extension and retraction is 4, and they are evenly arranged around the inner steel sleeve 5.

[0009] The hydraulic cylinder 2 is fixedly mounted on the fixed plate 4 by bolts.

[0010] One end of the inner steel sleeve 5 is welded to the inside of the measure pile 8.

[0033] like Figure 9 As shown.

[0034] A pin controller for connecting subgrade piles and engineering piles in underwater revetment construction at a wharf includes a pin 1 inserted into a pin hole 9 on an inner steel sleeve 5. The pin 1 is connected to the piston rod of a hydraulic cylinder 2, which is mounted on a fixed plate 4 via bolts 7. The fixed plate is connected to a reinforcing steel plate 3, which is mounted on an inner circular plate 6. A hydraulic control system is mounted on the inner circular plate 6. One end of the inner steel sleeve 5 is welded and fixedly installed in the subgrade pile 8, and the other end extends out of the subgrade pile 8. The pin hole 9 is located at the end of the inner steel sleeve 5 extending out of the subgrade pile 8. Figure 9 As can be seen, there are four pins 1 and four hydraulic cylinders 2 that control their extension and retraction, which are evenly arranged around the inner steel sleeve 5. The hydraulic cylinders 2 are fixedly mounted on the fixed plate 4.

[0035] like Figure 8 , 10 As shown, before assembling the engineering piles and the temporary piles, the hydraulic cylinder 2 first retracts the pin 1 into the inner steel sleeve 5. When the lower end of the temporary pile is inserted into the engineering pile and in place, the piston of the hydraulic cylinder 2 extends, extending the pin 1 through the inner steel sleeve 5 and into the waist-shaped pin hole of the engineering pile. At this time, the construction pile composed of the engineering pile and the temporary pile can be lifted and driven into the underwater foundation. When the second construction pile is assembled, it is lifted in the same way so that the male and female buckles on the second construction pile are aligned with the male and female buckles on the first construction pile, and then driven into the underwater foundation. After a set of construction piles is driven into the underwater foundation, the hydraulic cylinder is started remotely or by wire control to retract the pin 1. Then, the temporary pile is lifted by the lifting equipment to separate the first engineering pile from the first temporary pile. The first temporary pile and the new engineering pile are then combined to form the first construction pile in the second set of construction piles and driven into the underwater foundation. This cycle is repeated until the construction structure is completed.

[0036] The construction method compatible with this utility model is as follows:

[0037] Step 1. Material Preparation; First, determine the length of the engineering piles to be driven into the foundation based on geological exploration, and then fabricate circular pipe engineering piles using sheet pile manufacturing methods, such as... Figure 6 , 7 Simultaneously, male and female fasteners should be installed on opposite sides of the circular pipe piles so that adjacent piles can be connected as a whole through the insertion of the fasteners. A circumferential pin hole (commonly a waist-shaped hole) should be provided at the upper end of the circular pipe pile for connection with the temporary retaining pile. Lifting lugs should also be welded to the surface of the circular pipe pile. Secondly, the length of the temporary retaining pile should be determined according to the water depth, and the circular pipe temporary retaining piles should be manufactured using the sheet pile manufacturing method. Figure 3 , 45. Simultaneously, male and female fasteners are welded to both sides of the circular pipe pile so that adjacent foundation piles can be connected as a whole through the insertion of the male and female fasteners. At the same time, an inner steel sleeve with an outer diameter matching the inner diameter of the circular pipe column is welded to the lower end of the circular pipe column. Pin holes matching the pin holes on the circular pipe pile are opened circumferentially on the steel sleeve. A pin extension controller is installed inside the steel sleeve. Figure 8 , 9 As shown; the pin telescopic controller of this embodiment is a hydraulically controlled device that can be manually controlled on the construction vessel via remote control or wire control. The pin telescopic controller includes a pin 1, which is inserted into the pin hole on the inner lining steel sleeve 5. The pin 1 is connected to the piston rod of the hydraulic cylinder 2. The hydraulic cylinder 2 is mounted on the fixed plate 4. The fixed plate is connected to the reinforcing steel plate 3. The reinforcing steel plate 3 is mounted on the inner lining circular plate 6. The hydraulic control system is mounted on the inner lining circular plate 6.

[0038] Step 2. Assembly; such as Figure 10 As shown, the circular pipe foundation pile is lifted and placed on the roller frame of the assembly ship, and then the circular pipe engineering pile is lifted and placed on the movable roller frame of the assembly ship. The circular pipe engineering pile is moved horizontally and inserted into the steel sleeve on the circular pipe measure pile, so that the pin hole on the circular pipe engineering pile is aligned with the pin hole on the sleeve. The pin extension controller installed on the steel sleeve is activated, so that the pin extends and is inserted into the pin hole on the sleeve and the pin hole to complete the connection between the circular pipe measure pile and the circular pipe engineering pile, thus obtaining the construction pile. The assembly process is repeated to complete a set of 5 construction piles for later use.

[0039] Step 3. Piling; Transport the construction piles completed in Step 2 to the piling vessel. First, lift the first construction pile and drive it into the underwater foundation to the set elevation. Then, lift the second construction pile, align the male thread on the engineering pile and the auxiliary pile with the female thread on the first construction pile, and drive the second construction pile into the underwater foundation to the set elevation. Repeat this process until all the first set of construction piles are driven into the underwater foundation. Figure 11 As shown.

[0040] Step four, erect the temporary piles; activate the pin telescopic controller in the first construction pile to retract the pin back into the inner steel sleeve, as shown. Figure 12 As shown, the first temporary pile is lifted and sent to the assembly ship for assembly to form the first construction pile of the second group of construction piles. This construction pile is then connected to the last construction pile in the first group via a male and female interlocking mechanism and driven into the underwater foundation to the set elevation. Then, the pin extension controller in the second construction pile of the first group is activated, as shown... Figure 13This causes the pin to retract into the inner steel sleeve. The second temporary pile in the first group of construction piles is then lifted and transported to the assembly vessel, where it is assembled with the second engineering pile of the second group to form the second construction pile of the second group. This construction pile is then inserted into the first construction pile of the second group using the male and female interlocking mechanism and driven into the underwater foundation to the set elevation. Figure 14 , 15 16, and so on, until all the temporary piles in the first group of construction piles have been removed and all the piles in the second group of construction piles have been driven into the underwater foundation, such as Figure 17 Repeat the above operations to complete the construction of the third and fourth groups of construction piles, until all engineering piles are driven into the underwater foundation and the temporary piles are removed.

[0041] The above embodiments are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and equivalent substitutions can be made without departing from the principle of this utility model. All such technical solutions after improvements and equivalent substitutions to the claims of this utility model fall within the protection scope of this utility model.

[0042] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
