1 the significance of highway test and detection
For the quality management of highway engineering, the test and detection work is of great significance, because in highway construction, the engineering quality can be effectively detected. Highway test detection is very important, and highway engineering managers can compare the test results with relevant technical standards, so as to evaluate the engineering quality level.
1. 1 Highway test can improve the quality control level of building materials. In highway engineering construction, materials are the source, and the quality level of related materials directly determines the quality level after the highway is put into use. It is of great significance to ensure the quality of materials. Highway test can quantitatively analyze and evaluate the specific quality level of materials, improve the standardization of material management and realize the reasonable guidance of material application.
1.2 highway test can effectively control the project cost. Highway test can judge the materials used in engineering construction and analyze whether they meet the technical standards of engineering quality. Especially in the process of concrete proportioning, through road test, the concrete proportioning can be optimized, the project cost can be reduced and the economic benefit of the project can be improved on the premise of ensuring the project quality.
1.3 highway inspection provides a basis for judging highway quality defects and accidents. For the identification of highway quality defects and accidents, we can provide the necessary test data for analysis through effective test detection means, and get the reasons of defects and accidents. In addition, through the highway test, the highway quality can be evaluated at the completion stage, which is an important means of highway engineering quality acceptance.
1.4 The construction quality can be reasonably controlled and evaluated by means of test and detection. The evaluation of project quality includes two aspects: quality control during construction and evaluation and acceptance after completion. Experimental detection is a scientific and effective method, which is suitable for all stages of the project. Therefore, it is imperative to strengthen the test and detection work.
The application of 1.5 test means is also beneficial to the popularization and application of new processes, technologies and materials. Test new materials, new technologies and new processes to determine their applicability, feasibility, effectiveness and other related data, and accumulate effective experience for engineering construction.
2. Common problems in highway test and detection
At present, the problems existing in highway test and detection in China mainly focus on the detection of compactness and concrete strength. Therefore, in order to improve the level of highway test and detection, it is necessary to conduct in-depth analysis of these two issues.
2. 1 Problems in compaction degree detection. At present, there are many problems in compaction degree testing, which need the attention of testers. At present, the compaction test of compacted subgrade is mainly carried out by sand filling pipe with a diameter of 20 cm, which has a large amount of labor and has a certain impact on engineering construction. At the same time, the standard sand lacks inspection standards, so it is difficult to control the error of test data in the management of test data. However, the core sample method is mainly used for pavement compactness detection, which is destructive to the pavement and should not be taken more, resulting in unrepresentative data.
2.2 Problems existing in concrete strength testing. First of all, in the concrete strength detection, the engineering quality detection ignores the concrete strength detection. The concrete test of highway engineering in China mainly adopts the form of ledger, and engineers lack a clear understanding of the importance of concrete test. In the actual detection process, due to the long-term operation, the operator is relaxed during the detection process, and it is difficult to ensure the effectiveness of the specific detection test. Secondly, there are some problems in concrete pressure test. In China's highway test, concrete pressure test has always been a prominent problem, which needs to be further improved. In the concrete pressure test operation, most constructors lack standardized operation, and mostly rely on their own experience, ignoring the actual situation on site. Due to the lack of pressure test, the impact on the pavement in concrete construction is too large, which reduces the bearing capacity of the pavement. Finally, the road test operation lacks standardization. For the operation of concrete inspection, it is necessary to ensure the standardization of its operation. In the process of sample assembly, the vibrator should be operated accurately to ensure the correctness of the vibrator position. There is a lack of standardized management methods for the management of specimen and formwork, and it is difficult to ensure the standardized application of specimen and formwork in concrete inspection and testing.
3. Key points of strengthening test and detection work
In order to ensure the smooth development of highway engineering construction and the quality and safety of highway engineering, it is necessary to improve the level of highway engineering test and detection, and truly realize the standardization, scientificity and efficiency of highway engineering test and detection work. We need to pay attention to the problems existing in highway engineering test and put forward targeted solutions.
3. 1 It is very necessary to improve the overall level of testing personnel for the quality training of testing personnel, because only professionals can do their best, and only by knowing the technical knowledge of construction procedures can they be handy and meet the technical and quality requirements.
First, establish a perfect highway engineering testing standard. Effective detection standard is an important basis for highway engineering test detection, and it is also an important basis for standardizing detection. In order to solve the existing problems, it is necessary to improve the comprehensiveness of compaction test standards for highway engineering tests in China. In the highway engineering test in China, the test environment is changeable, and the standard sand density is constantly changing. Therefore, it is necessary to constantly improve the test standards to make them suitable for different regions and environments, and ensure the smooth progress of highway engineering tests through effective records.
3.2 Establish standardized management system for highway engineering test and detection. In China's highway engineering testing, the best way to solve the problems existing in concrete strength testing is to improve the existing system and improve the standardization of the testing system. When carrying out the concrete strength test, we should ensure the real-time and effectiveness of the concrete test, establish a perfect accounting system, improve the shortcomings of the existing concrete accounting system, improve the simplicity of the accounting system, and promote the improvement of the test management system by optimizing the accounting system.
3.3 Strengthen the implementation of highway engineering test. In the process of highway engineering test, it is necessary to implement the relevant management system and improve the understanding of relevant personnel on highway engineering test. For testers, the post responsibility system should be implemented and the post responsibilities should be strictly divided. The highway engineering test and detection work has high requirements for post personnel. If the professional level of post personnel cannot be guaranteed, the test results of highway engineering will be inaccurate. At present, many problems existing in highway engineering test and detection are closely related to the lack of quality of on-the-job personnel. In carrying out the highway engineering test and detection work, it is necessary to assess the on-the-job personnel and improve their attention to the detection work through the division of responsibilities, so as to ensure the high-quality development of the highway engineering test and detection work.
3.4 Responsibility lies with people, and establish the quality concept of employees. The enhancement of a systematic concept consciousness will inevitably drive the concepts of all links, so strengthening the quality concept is very important for the improvement of the highway engineering quality system. Managers at all levels should strictly control the quality, do their jobs well and take reasonable and effective measures to improve the quality management level. Then in practical engineering, we should ensure correct quality supervision and management, reasonable quality self-inspection, and gradually establish and improve the three-level quality assurance system. It is also necessary to strengthen the quality awareness of all departments, divide responsibilities fairly, clarify the division of labor, and truly implement the quality post responsibility system. In this way, the quality can be controlled separately, and all employees can be effectively encouraged to perform their duties.
4. Concluding remarks
To sum up, highway test and detection is an important measure to ensure the quality and safety of highway engineering, and also an important link to realize the safe construction of highway engineering. Engineering managers need to strengthen the study of relevant national quality standards and norms, establish effective highway test and detection norms, and carry out highway test and detection work with professional attitude and professional ethics. For the data results of highway test, inspectors should ensure their authenticity and objectivity, and make in-depth analysis of the test data, so as to better promote the quality and safety management of highway engineering and realize the long-term stability of highway engineering in China.
