specific Embodiment

[0063] For specific examples, see figure 1 , a method for detecting and appraising the construction quality of an underground waterproof project, characterized in that the steps are:

[0064] The first step, on-site investigation

[0065] The content of the on-site investigation includes the following aspects:

[0066] 1. The current situation of water seepage, change law, water source and damage degree of waterproof layer

[0067] 1) Current status of water leakage: location, form and amount of water leakage;

[0068] 2) Variation law of seepage water: whether there is periodicity, seasonality, periodicity, chance and long-term stability;

[0069]3) Water source: analyze whether the source of water is groundwater, stagnant water in the upper layer, or leakage water from the municipal pipe network, rainwater, snow water, green space water or domestic water;

[0070] 4) Degree of damage to the waterproof layer: whether the waterproof layer is partially damaged, or whether i...

Abstract

The invention relates to an underground waterproof engineering construction quality detection and identification method, in particular to a detection and identification method for inspection and acceptance of underground waterproof engineering construction under construction and leakage of existing building underground engineering water resistance. According to the underground waterproof engineering construction quality detection and identification method, by an infrared thermal imaging method, a microwave humidity method, a radar method, a water quality analysis and spraying test method, underground engineering leakage reasons are detected and identified by the aid of on-site verification. The method is reliable in analysis, scientific in judgment and accurate and reliable in conclusion.Besides, the underground waterproof engineering construction quality detection and identification method is scientific and compact in step, simple and reliable in detection step and suitable for popularization and use.

Description

technical field [0001] The invention relates to a detection and appraisal method considering the construction quality of an underground waterproof project, in particular to a leakage detection and appraisal method for the acceptance of the waterproof construction of the underground project under construction and the waterproof of the underground project of an existing building. Background technique [0002] In recent years, with the rapid development of underground buildings and underground projects, underground space has been fully utilized, such as subways, underground pipe corridors and common trenches, underground parking lots, underground commercial buildings, underground entertainment venues, underground Great Hall, underground hotel, etc., but reports of leakage problems in underground projects have never disappeared, and have become a very prominent project quality problem in construction projects. [0003] In 2014, the survey report of the China Building Waterproof ...
