“Hunan construction industry will completely tell others that manual hydraulic jacks are used to measure the static load detection era of pile foundations.” Recently, at the on-site demonstration meeting of JCQ-503 series static load tester introduced by Hunan Xinxiang Geophysical Exploration Engineering Co., Ltd. The leaders and experts of the Hunan Provincial Construction Department and the Changsha Municipal Construction Committee system praised the automatic remote monitoring static load instrument introduced by the company.
In the traditional static load detection, the manual manual hydraulic jack is often used for loading and replenishing. The measurement of the load value is measured by the oil pressure gauge connected to the jack, and then converted into a load according to the curve of the jack; Settling is observed with a dial indicator; data processing is performed manually. This kind of manual addition and replenishment method is difficult to ensure the stability of the load accurately and timely. The accuracy of load and settlement test is also relatively low. Human factors have great influence on the test results and are prone to errors. In addition, the inspectors need to observe and operate continuously before and after the test piles, and their labor intensity is high, and personal safety is difficult to guarantee. "Now it can automatically control the start and stop and flow of the oil pump. It can automatically load, replenish and stabilize the test pile, which fundamentally changes the test work environment, reduces the labor intensity, and ensures the safety of the testers. The accuracy and reliability of the test data." Yin Jianping, dean of the Hunan Institute of Non-ferrous Geological Exploration, said, "This means that in the past, the method of manual testing by sandbags and red bricks will be based on lack of competitiveness. The pile test is eliminated in the market."
In the current pile test experiments in Hunan Province, artificial sand piles are commonly used for static load experiments. It is neither safe nor accurate, and the tonnage of the experiment is not high. Hunan Non-ferrous Geological Exploration Institute has a keen insight into the pioneering market of the pile testing market. On the basis of Hunan Xinxiang Geophysical Exploration Engineering Co., Ltd., Changsha Xinxiang Geophysical Testing Service Co., Ltd. was established to make the prefabricated beam for pressure test weight. With the latest domestic experimental instruments, the pressure test tonnage can reach 2,500 tons, completely solving the safety and quality problems in the static load test, and the pressure test means and tonnage of our province have been raised to a new level.
As the earliest and largest pile foundation inspection service company in Changsha City, Changsha Xinxiang Geophysical Testing Service Co., Ltd., which was established less than one year ago, has sharply captured the market opportunities and introduced advanced Scientific and technological equipment, actively exploring the market, quickly occupied the Changsha large tonnage static load detection market with the advantages of high speed and large test tonnage. Currently, there are 6 inspection units in cooperation with the company.
