AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The application relates to a construction process of a foundation pit waterproof protection layer based on a cement fiber plate, which comprises the following steps: A, foundation pit bottom pouring, using concrete to pour the protection layer on the foundation pit bottom surface waterproof coiled material, measuring the plane quantity and plane size of the foundation pit inclined surface waterproof coiled material after pouring; B, plate matching, selecting prefabricated cement fiber plates, cutting and matching the cement fiber plates according to the plane quantity and plane size of the foundation pit inclined surface waterproof coiled material; C, bonding and fixing, configuring a bonding agent, dotting the bonding agent between the cement fiber plates and the waterproof coiled material, covering the cement fiber plates on the waterproof coiled material, then coating the bonding agent at the gaps between the cement fiber plates and between the cement fiber plates and the bottom surface, and forming the foundation pit inclined surface waterproof protection layer after solidification.
