Steel sheet pile is a kind of foundation pit supporting structure. It has the characteristics sheet pile suppliers of high strength, strong adaptability, compact combination, good water leakage, simple construction, fast speed, repeated use of the temporary project and so on. And the premise of these good performance is that it must meet the design requirements of its internal force.
In the practical construction process, the concrete selection of steel sheet pile according to the characteristics of the foundation pit engineering, through the economic, technical and construction period and other comprehensive comparison, the final optimization, from the overall consideration of the project cost to get the best choice. In the large-scale water conservancy construction site, the use of steel sheet pile must be considered in many aspects, the development of the foundation pit toward the deep, large, complex surrounding environment, making the excavation and support of deep foundation pit is more and more difficult. The application of steel plate supporting pile in water conservancy project construction has its own position and intrinsic value, and it will be gradually popularized.
Steel sheet pile support monitoring refers to the observation and analysis of the characteristics of foundation pit soil layer, the change of supporting structure and the same side environmental conditions in the process of foundation pit opening control and underground engineering construction, and timely feedback the observation results, so as to guide the design and construction. The computer monitoring has been used to provide the supporting system and environmental stress state and deformation data during the sheet pile suppliers construction process. Because of the improvement of information technology and reinforcement technology, deformation control of millimeter scale has been realized. If the groundwater level is high and the hydraulic power is large, the corresponding precipitation scheme should be chosen in terms of economy and safety. During the whole construction of foundation pit, the displacement and settlement should be observed throughout the whole process. And timely feedback data in order to find the problem in time, What are the benefits of Larsen steel sheet pile leasing adjust the program if necessary, so as to minimize the potential safety hazard.
