Abstract
Description
Technical Field
[0001] This utility model relates to a slope protection technology, and more particularly to an auxiliary device for the maintenance and construction of a deep-water wharf, specifically a measure pile for the reinforcement of underwater revetment pile foundations for wharfs. 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, and corresponding measures must be taken. However, due to the greater depth of deep-water wharves, directly driving engineering piles into the foundation would increase construction difficulty and reduce efficiency. New reinforcement methods must be adopted to solve construction problems, and using reinforcement piles to drive engineering piles into the foundation is an effective method. To the applicant's knowledge, there are currently no ideal reinforcement piles available for use. Utility Model Content

A pin telescopic controller 11 is installed in the inner steel sleeve 5, and the pin 1 controlled by the pin telescopic controller 11 can pass through the pin hole of the inner steel sleeve 5 and be inserted into the pin hole on the engineering pile 10.
[0007] The aforementioned pin telescopic controller 11 includes a pin 1, which is inserted into a 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 by bolts 7. 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.
[0008] There are four pins 1 and four hydraulic cylinders 2, which are evenly distributed on the inner steel sleeve 5.
[0009] The inner steel sleeve 5 is installed in the measure pile 8 by welding or threaded connection.

[0034] The method of using this utility model is as follows:
[0035] like Figure 2 , Figure 10-17 As shown.
[0036] A construction method for reinforcing underwater revetment pile foundations at a wharf, with the construction status as follows: Figure 2 As shown, it includes the following steps:
[0037] Step 1. Material Preparation; First, determine the length of the engineering piles to be driven into the foundation based on geological exploration. Fabricate circular pipe engineering piles 10 using sheet pile manufacturing methods. Simultaneously, install male and female fasteners 13 and 14 on opposite sides of the circular pipe engineering piles so that adjacent engineering piles can be connected as a whole through the insertion of the fasteners. Set circumferential pin holes (commonly oblong holes) at the upper end of the circular pipe engineering piles for connection with the temporary piles. Also, weld lifting lugs to the surface of the circular pipe engineering piles. Second, determine the length of the temporary piles based on the water depth. Fabricate circular pipe temporary piles using sheet pile manufacturing methods. Simultaneously, weld male and female fasteners to both sides of the circular pipe temporary piles so that adjacent foundation piles can be connected as a whole through the insertion of the fasteners. Simultaneously, on the circular... A steel sleeve with an outer diameter matching the inner diameter of the circular pipe column is welded to the lower end of the pipe column. A pin hole matching the pin hole on the circular pipe column is opened in the circumference of the steel sleeve. At the same time, a pin telescopic controller is installed inside the steel sleeve. The pin telescopic controller in this embodiment is a hydraulically controlled device that can be manually controlled on the construction vessel by remote control or wire control. The pin telescopic controller includes a pin 1, which is inserted into the pin hole on the 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 circular plate 6. The hydraulic control system is mounted on the inner circular plate 6.
[0038] Step 2. Assembly; such as Figure 10As 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 13 This 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.
