Ultrasonic pile testing: detection is an effective measure to improve engineering quality

2019-03-08

Inspection is an effective measure to improve engineering quality
In the construction of highway bridges, the raw materials, semi-finished products and finished materials required by the project shall be in accordance with the relevant test and detection procedures Ultrasonic pile testing indicates that In addition to routine tests for various raw materials, in order to investigate whether the materials really meet the construction technical requirements, sometimes necessary unconventional tests are required. After inspection according to technical regulations, unqualified materials are strictly prohibited to be used. If it is qualified, it can be used.
    The control of project quality mainly includes the construction unit's self inspection, supervision and sampling inspection, etc. in the construction process of highway bridges, firstly, for the supervision party, problems should be found, solved in time, timely sampling inspection, timely acceptance and evaluation, so as to truly play the role of the government's supervision function; secondly, for the supervision party, it is necessary to truly implement the three-level supervision, including "prior" and "in-process" We should pay close attention to these three steps. In the process of supervision, we should take test detection as an effective means, make full use of the relevant test equipment in the supervision center laboratory, strictly control the quality, so as to control the construction quality, prevent in advance, find problems, and solve them in time; third, for the construction party, there should be a special person in charge, full-time quality inspection, and adhere to the "self inspection" system. Set up site laboratory, and provide relevant test and detection personnel, establish a set of relatively perfect test and detection system.
For highway engineering, in addition to the quality control of the construction site, but also strict quality inspection. The unqualified projects shall be accepted by experience, and the rework treatment shall be resolutely given, and the phased construction summary shall be conducted appropriately to summarize the experience and lessons in the construction process.
Since the reform and opening up, with the development of highway and bridge and its role, people's understanding has changed, "to get rich, to build roads first" has become a consensus, speeding up the construction of transportation infrastructure has become people's conscious action. With the rapid development of highway in our province, it has become a common consensus to build bridges with high standard and high quality. Quality control, supervision and management as well as completion acceptance evaluation are the most important steps in highway engineering construction, which play an important role in highway engineering construction. Only by doing this work well can we ensure the smooth completion of highway construction.
