AI Technical Summary
The existing construction technology for waterproofing layers in foundation pits has problems such as long construction period and high cost, especially for elevator foundation pits with large slopes and deep sump pit slopes.
The waterproof protective layer is laid directly on cement fiberboard and installed in one go using an installation frame. The cement fiberboard and waterproof membrane are fixed together with adhesive, which simplifies the construction process and reduces the need for manual labor.
It enables short-cycle, low-cost, and high-efficiency construction of foundation pit waterproofing protective layers, avoiding the tedious process of layer-by-layer pouring, improving construction efficiency, and reducing labor requirements.
