[0002] A high-pile wharf is composed of a superstructure (pile platform or pedestal), pile foundation, shore connection structure, shore lock and wharf equipment. The superstructure constitutes the wharf surface and is connected to the pile foundation as a whole. It directly bears the vertical and horizontal loads acting on the wharf surface and transfers them to the pile foundation. The pile foundation is used to support the superstructure and transfer the load of the superstructure and the wharf surface to the deep foundation, which is also conducive to stabilizing the shore slope. The main function of the shore connection structure is to connect the pile platform with the land area of ​​the port area. High-pile wharves are often used in soft soil conditions with low foundation strength. High-pile wharves are air-permeable structures with small wave radiation and little impact on water flow. High-pile wharves are suitable for various foundations suitable for pile sinking, especially soft soil foundations. Rock-embedded piles can be used on rock foundations. Therefore, a modular assembled high-pile wharf structure and its construction method are particularly needed.

[0003] However, the existing high-pile wharf construction usually adopts on-site cast-in-place pile foundation, and then casts beams, longitudinal beams and panels on the top of the piles. This construction method has problems such as long construction period, frequent wet operations on site, and great influence of environmental factors. In addition, it is difficult to ensure high consistency of construction quality.

[0004] The purpose of the present invention is to provide a modular assembled high-pile wharf structure and a construction method thereof in order to solve the above-mentioned problems and overcome the defects of the prior art, as described in detail below.

[0005] To achieve the above object, the present invention provides the following technical solutions: A modular assembled high-pile wharf structure provided by the present invention comprises a prefabricated pile, the upper surface of the prefabricated pile is fixedly connected with a connecting block, the upper surface of the connecting block is bolted with a crossbeam, the lower surface of the crossbeam is provided with a connecting groove, the upper surface of the crossbeam is bolted with a longitudinal beam, the lower surface of the longitudinal beam is fixedly connected with a positioning block, one side surface of the longitudinal beam is fixedly connected with a clamping block, the upper surface of the longitudinal beam is bolted with a panel, and the lower surface of the panel is fixedly connected with a fixing block.

[0010] Preferably, two sides of the fixing block are attached to two groups of longitudinal beams, and the fixing block is placed on the surface of the transverse beam.

[0011] A modular assembled high-pile wharf structure further includes the following steps: Step 1: Prefabricated piles, beams, longitudinal beams and panels are manufactured in the prefabrication plant according to the design requirements, ensuring that the dimensions of each component are accurate and the strength meets the standards, and strict quality inspection and protection are carried out on the connection parts of each component; Step 2: Use piling equipment to drive the precast piles into the ground one by one to the designed depth, control the verticality and burial depth of the pile body, measure and adjust the top elevation of the precast piles, and clean the connection parts at the top of the piles; Step 3: Use a lifting device to lift the beam to the top of the precast pile, accurately position it and secure it to the precast pile (1), and check the connection. Step 4: Lift the longitudinal beams and cross beams, place and connect them tightly, and check the connection quality; Step 5: Lift the panel above the longitudinal beam, place and secure it, and check and adjust the flatness of the panel.

[0012] Preferably, in step 1, the raw materials of each component are strictly inspected, and high-precision molds and prefabrication processes are used to process and protect the connection parts of each component to prevent damage during transportation and storage.

In step 4, the longitudinal beam is lifted so that its blocks are aligned with each other, and after high-strength bolts are inserted, their positions and tightness are checked to ensure the stability of the longitudinal beam.

[0014] Preferably, it is characterized in that: in step 5, the panel is lifted by a tower crane, the high-strength bolts are tightened with a wrench, and the flatness of the panel is checked and adjusted using a 2m ruler and a feeler gauge. The beneficial effects are: 1.

Example 1

[0019] See also Figure 1-6A modular assembled high-pile wharf structure comprises a prefabricated pile 1, the upper surface of the prefabricated pile 1 is fixedly connected with a connecting block 2, the upper surface of the connecting block 2 is bolted with a crossbeam 3, the lower surface of the crossbeam 3 is provided with a connecting groove 4, the upper surface of the crossbeam 3 is bolted with a longitudinal beam 5, the lower surface of the longitudinal beam 5 is fixedly connected with a positioning block 6, a side surface of the longitudinal beam 5 is fixedly connected with a clamping block 7, the upper surface of the longitudinal beam 5 is bolted with a panel 8, and the lower surface of the panel 8 is fixedly connected with a fixing block 9. Through the arrangement of the above structure, when in use, multiple groups of prefabricated piles 1 are driven into the ground to play a basic role in supporting the entire wharf structure, transferring the load from the upper structure to the deep foundation, and the prefabricated piles 1 The top connection block 2 is tightly connected to the cross beam 3 by bolts. The connection block 2 not only enhances the integrity of the connection between the precast pile 1 and the cross beam 3, but also can effectively transmit vertical and horizontal forces. The cooperation between the connection groove 4 and the connection block 2 enables the cross beam 3 to be quickly positioned during installation, and can better distribute the force transmitted by the longitudinal beam 5 to the precast pile 1 evenly when subjected to force, thereby ensuring the stability of the structure. The positioning block 6 below the longitudinal beam 5 is stuck between the two groups of cross beams 3 to ensure the accurate position of the longitudinal beam 5 on the cross beam 3 and prevent it from being displaced in the horizontal direction. At the same time, the positioning block 6 can also transmit part of the vertical load to enhance the vertical bearing capacity of the structure. The multiple blocks 7 on one side of the longitudinal beam 5 are used to interact with the adjacent longitudinal beams 5. Splicing, by inserting high-strength bolts, a continuous longitudinal force transmission system is formed between the longitudinal beams 5, which can transfer the load on the panel 8 to the cross beam 3, and further transfer it to the precast pile 1 foundation. This splicing method improves the overall bending and shearing resistance of the longitudinal beam 5, ensures the longitudinal structural strength and stability of the dock, and adapts to various stress conditions of the dock during use. The panel 8 serves as a working platform of the dock and bears direct use loads. The fixing blocks 9 below it fit the longitudinal beams 5 on both sides and are placed on the surface of the cross beam 3. This structure not only ensures the stable placement of the panel 8 on the frame composed of the longitudinal beams 5 and the cross beams 3, but also can transfer the load on the panel 8 to the longitudinal beam 5 through the fixing blocks 9. and crossbeam 3, and finally transferred to the precast pile 1 foundation. The panel 8 is connected to the longitudinal beam 5 by bolts, which further enhances the integrity of the panel 8 and the lower structure and prevents the panel 8 from loosening, warping and other problems during use, thereby ensuring the flatness and safety of the dock surface and meeting the operational requirements of cargo loading and unloading, vehicle driving and personnel walking. This modular assembled high-pile dock structure effectively transfers various loads acting on the dock to the foundation through the reasonable connection and coordinated work between the components, thereby ensuring the stability and reliability of the dock structure under different working conditions. At the same time, its modular design and assembled construction method improve the construction efficiency and quality, and facilitate the construction and maintenance of the dock.

[0020] Furthermore, multiple groups of precast piles 1 are arranged, and the inner dimensions of the connecting blocks 2 match the outer dimensions of the cross beams 3. Through the arrangement of the precast piles 1, when in use, multiple groups of precast piles 1 form a pile group foundation, which can better adjust the force of each pile and avoid damage caused by excessive load on local piles.

[0021] Furthermore, multiple groups of cross beams 3 and multiple groups of longitudinal beams 5 are provided. Through the arrangement of the cross beams 3 and longitudinal beams 5, when in use, the arrangement of multiple groups of cross beams 3 and longitudinal beams 5 can effectively disperse the load transmitted from the upper structure of the dock, fully utilize the bearing capacity of the pile group foundation, and ensure the safety of the entire dock structure.

[0022] Furthermore, both sides of the positioning block 6 are fitted to the two groups of cross beams 3, and multiple groups of clamping blocks 7 are arranged on the surface of one side of the longitudinal beam 5. Through the arrangement of the positioning block 6, when in use, it plays a precise positioning role in the installation process of the longitudinal beam 5. This fitting design enables the longitudinal beam 5 to be quickly and accurately placed at the predetermined position of the cross beam 3. Construction personnel can determine the correct installation position of the longitudinal beam 5 based on the position of the cross beam 3, thereby ensuring the assembly accuracy of the entire wharf structure, helping to improve construction efficiency and reduce installation errors.

[0023] Furthermore, the longitudinal beams 5 are spliced ​​with each other through the clamping blocks 7, and the panels 8 are provided in multiple groups. Through the setting of the clamping blocks 7, when in use, the clamping blocks 7 provide a reliable connection method, which can ensure the tightness of the connection between the longitudinal beams 5 and prevent the longitudinal beams 5 from loosening or detaching, thereby ensuring the stability of the longitudinal force transmission path.

[0024] Furthermore, the two sides of the fixing block 9 are attached to the two groups of longitudinal beams 5, and the fixing block 9 is placed on the surface of the cross beam 3. Through the setting of the fixing block 9, when in use, the two sides attached to the two groups of longitudinal beams 5 can ensure that the panel 8 is accurately placed on the predetermined position of the longitudinal beams 5 in the longitudinal direction, and placed on the surface of the cross beam 3 so that the panel 8 can also be accurately positioned in the transverse direction. Example 2

[0025] A construction method for a modular assembled high-pile wharf further includes the following steps: Step 1: Prefabricated piles 1, beams 3, longitudinal beams 5 and panels 8 are manufactured in the prefabrication plant according to the design requirements, ensuring that the dimensions of each component are accurate and the strength meets the standards, and strict quality inspection and protection are carried out on the connection parts of each component; Strictly inspect the raw materials of each component, use high-precision molds and prefabrication processes, and process and protect the connection parts of each component to prevent damage during transportation and storage. Step 2: Use piling equipment to drive the prefabricated piles 1 into the ground one by one to the designed depth, control the verticality and burial depth of the pile body, measure and adjust the pile top elevation of the prefabricated piles 1, and clean the connection parts of the pile top; Use a total station to control the verticality of the pile body, control the depth of the pile according to the geological conditions and design requirements, use a level to measure the elevation of the pile top and make adjustments, and clean up the debris and soil at the connection part of the pile top; Step 3: Use the lifting equipment to lift the beam 3 to the top of the precast pile 1, fix it firmly to the precast pile 1 after accurate positioning, and check the connection parts; A large-scale lifting crane is used to lift the beam 3. After the connection parts are accurately butted, a wrench is used to tighten the bolts and the reliability of the connection is checked.

[0026] Step 4: Lift the longitudinal beam 5 to between the cross beams 3, place and connect them tightly, and check the connection quality; Lift the longitudinal beam 5 so that its blocks 7 are aligned with each other, insert the high-strength bolts and check their position and tightening degree to ensure the stability of the longitudinal beam 5; Step 5: Lift the panel 8 above the longitudinal beam 5, place and fix it, and check and adjust the flatness of the panel; Use a tower crane to lift panel 8, use a wrench to tighten the high-strength bolts, and use a 2m ruler and feeler gauge to check the flatness of panel 8 and make adjustments.

[0027] Working principle: Multiple groups of precast piles 1 are driven into the ground to support the entire wharf structure and transfer the load from the upper structure to the deep ground. The connection block 2 on the top of the precast pile 1 is tightly connected to the crossbeam 3 by bolts. The connection block 2 not only enhances the integrity of the connection between the precast pile 1 and the crossbeam 3, but also effectively transfers the vertical and horizontal forces. The cooperation between the connection groove 4 and the connection block 2 enables the crossbeam 3 to be quickly positioned during installation, and when subjected to force, it can better evenly distribute the force transferred from the longitudinal beam 5 to the precast pile 1, thereby ensuring the stability of the structure. The positioning block 6 below the longitudinal beam 5 is stuck between the two groups of cross beams 3 to ensure the accurate position of the longitudinal beam 5 on the cross beam 3 and prevent it from being displaced in the horizontal direction. At the same time, the positioning block 6 can also transfer part of the vertical load to enhance the vertical bearing capacity of the structure. The multiple blocks 7 on one side of the longitudinal beam 5 are used to splice with adjacent longitudinal beams 5. By inserting high-strength bolts, a continuous longitudinal force transmission system is formed between the longitudinal beams 5, which can transfer the load on the panel 8 to the cross beam 3 and further to the precast pile 1 foundation. This splicing method improves the overall bending and shear resistance of the longitudinal beam 5. The panel 8 is a working platform of the wharf, which bears direct loads. The fixing blocks 9 below the panel 8 are attached to the longitudinal beams 5 on both sides and placed on the surface of the cross beams 3. Such a structure not only ensures the stable placement of the panel 8 on the frame composed of the longitudinal beams 5 and the cross beams 3, but also transfers the load on the panel 8 to the longitudinal beams 5 and the cross beams 3 through the fixing blocks 9, and finally transfers it to the prefabricated pile 1 foundation. The panel 8 is connected to the longitudinal beams 5 by bolts, which further enhances the integrity of the panel 8 and the lower structure, prevents the panel 8 from loosening and warping during use, ensures the flatness and safety of the wharf surface, and meets the requirements of cargo loading and unloading, vehicle driving and personnel walking. This modular assembled high-pile wharf structure effectively transfers various loads acting on the wharf to the foundation through the reasonable connection and coordinated work between the components, ensuring the stability and reliability of the wharf structure under different working conditions. At the same time, its modular design and assembled construction method improve the construction efficiency and quality, and facilitate the construction and maintenance of the wharf.
