The annual service revenue is nearly one million.
Structural and component defects, impurities, research directions for health diagnosis, research results of structural foundation safety static characteristics, can automatically detect and automatically record the stress state of the foundation structure, and automatically analyze and automatically process to determine the ultimate compressive ultimate bearing capacity Determine whether the vertical compressive bearing capacity can meet the design requirements; determine the pile body and pile end resistance through the internal force and deformation test of the pile body, and provide reliable parameter information for the designer to optimize the design and save the basic cost. The method is convenient to operate and has good reliability. The annual social service income is about 4 million yuan.
The research introduced the international advanced dynamic piling analysis system (PDA) combined with the actual engineering geological conditions in Zhenjiang area, and developed the dynamic detection method of pile foundation bearing capacity. This method overcomes the traditional static load detection method of pile foundation bearing capacity. Although the result is correct and intuitive, it is time-consuming, laborious, and costly. Some shortcomings that cannot be implemented due to site conditions can be used to detect piles quickly, accurately and at low cost. Vertical compressive bearing capacity and pile body quality; the pile body stress and hammer energy transfer ratio of precast piles can also be monitored to provide a basis for the selection of piled pile parameters and pile length. The annual social service income is about 2 million yuan.
