Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a recyclable steel sheet pile protection device for reducing disturbance during pipe pile construction. Background Technology
[0002] In highway reconstruction and expansion projects, PHC pipe pile construction is a common method for foundation reinforcement. PHC pipe piles are widely used in foundation reinforcement projects due to their convenient construction and high bearing capacity. However, when PHC pipe piles are constructed at the junction of new and old roadbeds, especially on the new roadbed side, they often disturb the adjacent old roadbed, particularly when the old roadbed is a sloping terrain. Strong vibrations are generated during pile driving, which propagate outwards from the pile, potentially leading to slope instability, increasing the risk of landslides in the old roadbed, and affecting the road's service life and traffic safety. Current technologies primarily focus on optimizing pile driving equipment and construction processes to reduce construction disturbance, with relatively little research on installing protective devices at the toe of the old roadbed slope to minimize disturbance. Furthermore, existing protective devices are mostly single-use, without considering reuse after construction, often resulting in increased costs and resource waste. Therefore, there is an urgent need for a protective device that can effectively reduce the disturbance to the old roadbed caused by PHC pipe pile construction and also has recyclability.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example 1:
[0026] Please combine Figures 1-5 The recyclable sheet pile protection device for reducing construction disturbance of pipe piles in this embodiment includes a sheet pile assembly 2 connected in sequence. The sheet pile assembly 2 includes a sheet pile structure 3, a rubber pad 4 disposed on the inner side wall of the sheet pile structure 3 for shock absorption, a protective structure 5 disposed at the bottom of the sheet pile structure 3 for protecting the rubber pad 4, and a connecting mechanism 6 for fixing the sheet pile structure 3 to the rubber pad 4 and the protective structure 5.
[0027] The sheet pile structure 3 includes a sheet pile 31, L-shaped side plates 32 fixed to both sides of the sheet pile 31, overlapping plates 33 fixed to the side plates 32, and connecting holes 34 opened on the sheet pile 31 to connect with the connecting mechanism 6.
[0028] The protective structure 5 includes a U-shaped storage plate 51 disposed between the sheet pile 31 and the rubber pad 4, and a positioning plate 52 disposed on the inner side wall of the storage plate 51 for positioning the rubber pad 4.
[0029] The connecting mechanism 6 includes a bolt fitted onto the connecting hole 34, and the bolt thread is fitted with a nut.
[0030] Both the rubber pad 4 and the storage plate 51 have two through-holes that mate with the connecting mechanism 6.
[0031] The sheet pile structure 3 is an integral part of the structure and is made of corrosion-resistant material.
[0032] Rubber pad 4 is made of wear-resistant engineering rubber material.
[0033] The outer ring of the bolt is fitted with a spring washer and a flat washer to prevent loosening.
[0034] Example 2:
[0035] like Figure 1 and Figure 6 As shown, construction preparation:
[0036] A thorough cleanup was conducted at the toe of the slope of the old roadbed 8, removing weeds, stones, and other debris to ensure a level and clean construction site. According to design requirements, measuring tools were used to measure and calibrate the embedment position and depth of the steel sheet pile structure 3. Based on the measurement results and construction design plan, the required steel sheet piles 31, rubber pads 4, displacement sensors, and other related equipment were transported to the construction site. The steel sheet piles 31 should be made of high-strength, corrosion-resistant materials, the rubber pads 2 should be made of high-strength engineering rubber, and the displacement sensors should have real-time data transmission capabilities to ensure timely monitoring of the slope's stability.
[0037] Install protective structures and monitoring equipment:
[0038] Based on the actual dimensions of the sheet pile 31, the rubber pad 4 is cut using a cutting tool to ensure it fits snugly against the sheet pile 31, with a thickness of at least 5cm. The cut rubber pad 4 is then moved to the installation position of the sheet pile 31. The receiving plate 51 is fitted onto the bottom of the sheet pile 31, and the rubber pad 4 is inserted into the inside of the receiving plate 51 to abut against the positioning plate 52. At this point, the mating holes 2 on the rubber pad 4 and the receiving plate 51 are aligned with the pre-drilled mating hole 34 on the sheet pile 31. Bolts are then inserted and tightened with nuts. Spring washers and flat washers are applied to the bolts to prevent loosening, ensuring a secure connection between the rubber pad 4 and the sheet pile 31 without any loosening. Simultaneously, displacement sensors are installed on the old roadbed slope for subsequent monitoring.
[0039] Piling construction and monitoring:
[0040] Move the hydraulic static pile driver to the installation position, lift the sheet pile structure 3, align its bottom with the pre-marked position, and then start the pile driving equipment to slowly drive the sheet pile structure 3 into the soil layer at the toe of the old roadbed slope and below. After the sheet pile structure 3 is driven into the ground, leave a height of about 0.5m above the road surface. Then, insert the next sheet pile structure 3 along the reserved height of the previous sheet pile structure 3, and after firmly connecting them, slowly drive it into the soil layer of the new roadbed 7 using the pile driver. Continue this operation until the designated position is reached. Throughout the pile driving process, the operating parameters of the pile driving equipment and the status of the sheet piles 31 must be closely monitored. Use sensors to monitor data in real time and adjust the operating parameters of the pile driving equipment (such as pile driving pressure, pile driving speed, etc.) as needed. At the same time, pay attention to the penetration depth and verticality of the sheet piles 31. If any deviation in penetration depth or verticality is found, effective corrective measures should be taken immediately. When the vibration-damping sheet pile structure has been driven to the design depth, stop the pile driving equipment.
[0041] Equipment recycling:
[0042] After the above work is completed, PHC pipe pile 9 construction can begin on one side of the new roadbed 7. After the PHC pipe pile 9 construction is completed, the sheet pile structure 3 can be retrieved. The hydraulic static pile driver is moved to the position of the sheet pile structure 3, and the top of the sheet pile structure 3 is firmly clamped using the clamping device. Then, a pulling force is slowly applied to pull the sheet pile structure 3 out of the soil. During the extraction process, the extraction speed must be carefully controlled to avoid damage to the sheet pile structure 3 due to excessive speed. After the sheet pile structure 3 is pulled out, the rubber pad 4 and sheet pile 31 are immediately removed using tools. During disassembly, care must be taken to avoid damaging the rubber pad 4 and sheet pile 31. The removed rubber pad 4 and sheet pile 31 are inspected for deformation or damage. Those rubber pads 4 and sheet piles 31 that can still be used are cleaned, organized, and properly stored for future use.
[0043] This invention effectively reduces construction disturbance. The rubber pads can effectively absorb and mitigate vibrations and impacts generated during construction, reducing the impact of construction disturbances on the old roadbed slope and improving the overall stability of the slope. The steel sheet pile structure has a recyclable function. By reusing the steel sheet piles and shock-absorbing rubber pads, construction costs are reduced, resulting in good economic benefits and reducing resource consumption and environmental burden. It is suitable for various slope terrains and soil conditions, possessing strong adaptability and versatility. The detachable shock-absorbing rubber pads and steel sheet piles facilitate installation and replacement during the construction preparation and completion stages.
[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
