Review opinions of various professions
Review opinions on construction drawings of geotechnical specialty
1. This project is the reconstruction of the original building, and there is no design scheme for the reconstruction part. According to the description in the survey report, the original building (1 floor) is added, and the drilling holes with the depth of 10.2 ~ 17.8 m are arranged around the original building for survey. Through drilling, it is basically found that the surface layer of foundation is 0.4 ~ 1.0m thick fill, followed by Quaternary residual red clay and Devonian limestone. Drilling revealed that the buried depth of bedrock in the site was between1.6 ~12.7m, that is, the thickness of the upper soil layer changed greatly. According to the borehole elevation of 95.8 ~ 103.2 m, the site elevation difference is large.
2. Only six standard penetration tests were conducted in the red clay layer in this survey, and no samples were taken in the indoor test. Most relevant geotechnical parameters are duplicated. Geotechnical investigation report on single apartment of Kunming Cheng Chun Lakeside Tourism Real Estate Co., Ltd.? The information in this newspaper, especially the one attached at the end of this newspaper? The index table of main physical and mechanical properties of each soil layer is copied from the test results of some boreholes in a single survey and compiled as the test results of some boreholes in this survey. This is inappropriate, which violates the requirements of geotechnical engineering specifications for detailed survey, does not conform to the relevant provisions of survey document compilation, and the index data can not reflect the actual situation of the site.
3. Add stories to existing buildings, find out the form, size, buried depth, bearing layer and bearing capacity of existing foundations, check the deformation, take measures to control the additional settlement caused by additional load after adding stories, and coordinate the settlement and deformation of new and old foundations if there are new foundations. It is suggested in the report that the 1 layer should be covered by manual digging piles, with limestone as the bearing layer. It is necessary to further consider, or according to the upper load, properly remove the shallow buried part of bedrock, and then adopt mattress treatment, with red clay as the bearing layer. In the process of adding stories, it is necessary to observe the settlement of buildings. The elevations used in this report are hypothetical elevations, and the connection with the urban construction height system should be established. IV. The report copied the drilling sampling data of other projects and compiled the physical and mechanical properties index table of this project. The sampling test work of red clay layer should be supplemented, and the physical and mechanical properties index statistics table should be made separately before it is provided for design use.
