Three Essential Criteria: Slip Resistance, Load-Bearing Capacity, and Joint Spacing"},"content":{"rendered":"<article style=\"max-width: 800px; margin: 0 auto; padding: 20px; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif; line-height: 1.8; color: #333; text-align: left;\">\n\n  <p style=\"text-align: left; margin-bottom: 20px;\">Selecting the right cover plates for dry fountains is one of the most easily overlooked technical details in dry fountain design, yet it is a core decision that directly impacts safety and operational maintenance costs. Direct Conclusion: Dry fountain cover plates must simultaneously meet three mandatory standards\u2014anti-slip properties, load-bearing capacity, and gap size\u2014and none can be overlooked. If anti-slip performance is insufficient, children may slip and fall on wet cover plates, resulting in injury; insufficient load-bearing capacity causes the covers to deform or break under the weight of vehicles or crowds; and gaps that are too wide allow children\u2019s fingers or heels to get caught between the covers, which is the most common source of complaints and accidents. This article systematically breaks down the specific parameters of these three mandatory standards and compares the pros and cons of common cover materials.<\/p>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">Criteria for Selecting Ground Covers for Dry Fountains: First, Understand the Functional Purpose of the Ground Cover<\/h2>\n\n  <p style=\"text-align: left; margin-bottom: 20px;\">The core design principle of a dry fountain is that the nozzles are flush with the ground, and the water\u55b7s out from the ground and flows into a collection basin hidden underground. In this structure, the ground cover plate serves three functions:<\/p>\n\n  <ul style=\"padding-left: 20px; margin-bottom: 20px; text-align: left; list-style-type: disc;\">\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Safe Travel Area:<\/strong>When the fountain is not in operation, the cover must meet the safety and load-bearing requirements for standard ground paving.<\/li>\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Drainage Channels:<\/strong>When the fountain is in operation, the water that falls back to the ground flows through the gaps in the cover into the catch basin; it is essential to ensure efficient drainage.<\/li>\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Equipment Protective Cover:<\/strong>It must be able to withstand foot traffic and occasional vehicle loads, while also allowing for easy disassembly for periodic maintenance.<\/li>\n  <\/ul>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">Mandatory Standard 1: Slip Resistance<\/h2>\n  <p style=\"text-align: left; margin-bottom: 20px;\">Slip resistance is the most important safety criterion for cover plates. During the operation of dry fountains, the ground remains continuously slippery; if the cover plates do not have a sufficient coefficient of friction (COF), falls are inevitable. It is recommended that the coefficient of friction (COF) for cover plates in public children\u2019s play areas be no less than 0.6.<\/p>\n\n  <figure style=\"margin: 20px 0; overflow-x: auto;\">\n    <table style=\"width: 100%;
