Abstract

As a new type of construction material, high performance self-compacting concrete can effectively improve the compactness and impermeability of the building after pouring. In order to optimize the effect of waterproofing and anti-cracking construction of underground engineering, the waterproofing and anti-cracking construction technology of underground engineering based on high performance self-compacting concrete is proposed. A construction project in the north, focusing on the basement wall, adopts a combination of external defense and internal paste methods for waterproofing and anti-cracking construction. Mechanical excavation is carried out to a predetermined distance above the design base elevation, followed by base repair, laying of the bedding template, pouring of the concrete bedding, and subsequent maintenance. The location and thickness of the masonry are determined, the reinforcing steel grid is arranged and fixed, and then mortar is filled to form a waterproof and anti-crack layer. The wall surface is thoroughly cleaned at the grassroots level, and an additional waterproofing membrane layer is applied for paving construction. Finally, through the design of monitoring points, the humidity and conductivity of different areas are monitored. The results show that the humidity value of the monitoring points is maintained between 36% and 44%, and the conductivity is between 32.9μS/cm and 52.3μS/cm, which proves that the waterproofing layer after construction can effectively prevent the penetration of water.
