Description

Technical Field

[0001] This utility model relates to the field of rapid flood control, specifically to a plastic steel sheet pile fixing base for urban emergency flood control and water retention. Background Technology

[0002] Floods are among the most frequent and destructive natural disasters in human history. Typically triggered by torrential rains, floods are characterized by their suddenness and instantaneous destructiveness. They often cause severe damage to urban power lines and public facilities, soak large quantities of urban goods, disrupt power supply, transportation, and communication systems, and in severe cases, destroy roads and houses, posing a serious threat to the lives of urban residents.

[0003] Currently, various regions across the country are vigorously promoting the construction of drainage and flood control facilities, and significant progress has been made in rapid flood control. In particular, plastic steel sheet piles, which have emerged in recent years, have been favored by relevant flood control departments and enterprises. Plastic steel sheet piles are characterized by high strength and light weight, have high seepage prevention capabilities, and can effectively resist flood intrusion. Plastic steel sheet piles are easy to construct and do not require large equipment to be brought to the site, which is conducive to rapid construction in flood-prone areas with complex terrain and small areas.

[0004] Current methods for urban flood control using sheet piles require first fixing steel columns on both sides, and then vertically inserting and splicing sheet piles one by one from top to bottom between the two steel columns. This method creates seepage channels at the contact points between the sheet piles and the ground, as well as at the splicing points. To address this, a plastic-steel sheet pile fixing base for urban emergency flood control is proposed. This fixing base can be pre-embedded in flood-prone areas of the city. In the event of a sudden flood, the plastic-steel sheet piles can be directly and vertically assembled with the fixing base, resulting in rapid and efficient flood control. Furthermore, both the fixing base and each plastic-steel sheet pile have an integrated rubber waterstop, effectively preventing flood leakage. The flood control speed and effect are superior to current urban flood control metal sheet piles.

[0005] In recent years, the rapid pace of urbanization has made underground parking lots play a crucial role in urban construction. However, due to the unpredictable nature of rainstorms and the limitations of urban drainage systems, underground parking lots often face the risk of flooding due to rainwater accumulation. This not only damages vehicles but may also threaten personal safety, while increasing the difficulty and cost of drainage and maintenance. Currently, plastic-coated steel sheet piles are widely used in the construction of enclosure and drainage facilities for underground parking lots due to their excellent waterproof performance and structural strength. However, the traditional straight expansion joint design has revealed some shortcomings in practical applications. First, straight expansion joints are prone to causing bumps when vehicles pass over them, affecting the comfort and safety of vehicle passage. Second, due to the influence of water pressure and foundation settlement during rainstorms, straight expansion joints have poor sealing and durability, easily leading to leakage and further exacerbating the water accumulation problem in parking lots.

[0006] To address the aforementioned issues, a W-shaped expansion joint design is proposed. This design not only matches the W-shaped cross-section of the plastic steel sheet pile, serving as its bottom support and improving the overall structural stability and sealing, but also effectively reduces vehicle bumps during driving, enhancing smoothness and user experience. Furthermore, the W-shaped design offers greater elasticity and cushioning, better adapting to foundation settlement and structural micro-deformations, thereby improving waterproofing performance and extending service life.

[0007] This utility model aims to address the practical pain points in traditional design by improving the shape and function of expansion joints, significantly enhancing the drainage capacity, structural safety, and user comfort of underground parking lots under extreme weather conditions, and providing more reliable technical support for urban infrastructure.
