Abstract

The invention discloses a waterproof structure of a basement exterior wall in a limited space, which comprises a raft foundation, a cushion layer and a self-waterproof reinforced concrete exterior wall, and a plain concrete layer, a flexible waterproof layer and an insulation layer are sequentially arranged on the exterior of the self-waterproof reinforced concrete exterior wall , there is a circular groove on the outer side of the insulation layer, the position and quantity of the circular groove correspond to the position and quantity of each anchor rod in the water-stop curtain of the deep mixing pile, the bottom and the wall of the circular groove are provided with foam glue, and the outside of the foam glue is made of waterproof mortar It is sealed with JS paint and connected with the insulation layer. A reinforced concrete force transmission plate belt is set at the level of each floor of the waterproof reinforced concrete exterior wall. The invention also discloses a construction method for the waterproof structure of the basement wall in a limited space, adopts multiple waterproof measures, has simple operation, low cost, superior performance and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a waterproof structure and a construction method for a basement wall in a limited space. Background technique [0002] At present, with the rapid development of my country's economy, the density of urban buildings is close to saturation, the underground pipelines are intricate, and the construction of ultra-deep basements in high-rise buildings is increasingly restricted by environmental factors such as the narrow surrounding sites. The foundation pit support structure of composite soil nail walls is adopted. The gap with the basement exterior wall is very narrow, which brings great difficulties or even impossibility to the waterproofing construction. The waterproof quality of the basement exterior wall is an important point and a difficulty in the safety and use of underground structures. The laying of waterproof membranes is a key process to ensure the waterproo...
