Deep foundation pit quality supervision method

Abstract

The invention discloses a deep foundation pit quality supervision method, which comprises the following steps: the step S10, obliquely shooting a construction site by adopting an unmanned aerial vehicle, and collecting surface feature side texture and position information of the construction site; the step S20, establishing a three-dimensional live-action model of the deep foundation pit according to the obliquely shot image; the step S30, establishing a design BIM model according to the design file; the step S40, performing measurement, comparison and analysis on the three-dimensional live-action model of the deep foundation pit and the designed BIM model; the step S50, according to specifications and design requirements, determining allowable deviation values of different parts of the deep foundation pit; the step S60, highlighting the part exceeding the allowable deviation value; and the step S70, rechecking the parts exceeding the allowable deviation value. According to the method, the actual conditions of the engineering site in different periods and the designed BIM model can be compared and analyzed, the construction deviation condition is rapidly and accurately detected, and an efficient scientific and technological means is provided for site supervision, inspection and acceptance.

Description

technical field [0001] The invention relates to the technical field of water engineering quality supervision methods, in particular to a deep foundation pit quality supervision method based on oblique photography and BIM technology. Background technique [0002] The quality supervision of waterworks projects is based on relevant laws and regulations and mandatory standards for engineering construction. The implementation of government-supervised activities in the case of obligations. [0003] The quality supervision of the construction stage of the water deep foundation pit project is one of the most important stages of the project. This process takes a long time and involves many people. Once any quality problem occurs in any part, it will affect the final quality of the project to varying degrees. , What's more, it will lead to subsequent safety and quality accidents of the project, affecting the national economy and people's livelihood. [0004] Under the traditional mo...

[0003] The quality supervision of the construction stage of the water deep foundation pit project is one of the most important stages of the project. This process takes a long time and involves many people. Once any quality problem occurs in any part, it will affect the final quality of the project to varying degrees. , What's more, it will lead to subsequent safety and quality accidents of the project, affecting the national economy and people's livelihood

[0004] Under the traditional model, the quality inspection of deep foundation pit projects is mostly done through the methods of "listening", "seeing", "checking", "side" and "inspecting" to complete the daily inspection and foundation trench inspection work, which requires relatively high professional and experience requirements for supervisors , the supervision results are paper-based, not visually intuitive enough
