Construction project quality inspection
1. Introduction
“Demonstration project of preparation of the new chemical materials from the coal powder” of Yulin Chemical Company is currently the largest coal chemical project under construction in the world, covering an area of 13 square kilometers with a total investment of RMB 125 billion. We have undertaken the foundation treatment test and detection work of this project, with a total value of RMB 6.75 million in contracts of test and inspection.
2. Treatment solution
Different buildings and structures have different requirements for the engineering performance of a foundation, so how to reflect the bearing characteristics of each soil layer needs to be tested by sensors.
Setting of the stress sensors for the cast-in-place piles
3. Construction situation
The type of pile foundation selected for this project is rotary bored pile, and the quality inspection methods are dominated by low strain test, high strain test and static load test.
Site conditions of engineering quality inspection
4. Achieved accomplishment
Corresponding engineering parameters of strata are obtained through experiments, which provides a basis for optimizing the design scheme and makes the engineering construction more reasonable and economical.
5. FAQ
Q1: What should be paid attention to in foundation treatment test and inspection of large-scale projects?
A: Because of the large area of construction land and many buildings or structures, the tests in the civil engineering stage of large-scale projects are rich in content and heavy in workload, so it is necessary to comprehensively assess the test results in combination with survey data, construction overview and other information.
Q2: How did you stand out from many other bidders?
A: We have participated in some similar large-scale chemical projects in recent years, and summarized the technical requirements of geotechnical engineering of chemical projects. Moreover, our technical team is relatively stable, rich in experience, strong in service concept, and has a good reputation among peers.
Q3: Is there any difference between sand foundation treatment quality inspection and loess foundation treatment quality inspection?
A: Different geological conditions, different building grades, different ways of foundation treatment, different testing contents and different assessment methods.
Q4: What is the cost of geotechnical engineering test?
A: Geotechnical engineering test costs depend on many aspects. For this project, in addition to the direct test costs, transportation costs are also considerable.
