What are the advantages of double-sided submerged arc welding spiral steel pipe Larsen steel sheet pile construction
It is also important to choose the method of driving steel sheet piles. As discussed, the method of driving steel sheet piles by roots will reduce the driving performance of sheet piles. When using Japanese static pile driver, it is impossible to select the most suitable pile type according to the surface modulus if the rigidity of sheet piles is to be improved to the maximum extent because of the method of driving steel sheet piles by roots. Many factors need to be taken into account in choosing the pile type which is economical, reasonable and easy to drive. The recommended selection process
In order to evaluate the characteristics and drivability of main strata, two kinds of piling methods and three types of piling machines are considered to help determine the appropriate range of sheet pile section. Whether the selected steel sheet pile type and driving method are suitable also depends on whether the steel sheet pile is driven by a single pile or by a pile. It should be noted that the length of the pile and the thickness of the king's layer are not taken into account, and these factors will be taken into account in the subsequent tables.
It is a complicated process to choose the suitable pile type in the clay soil of double-sided submerged arc welding spiral steel pipe. It is usually based on experience. The pile driving force can also be estimated by the surface area of the pile and the characteristics of the clay soil, which can be used for preliminary estimation.
The dynamic characteristics of impact piling should keep a certain penetration no matter which method is adopted. Assuming that the stratum is drivable, the size and type of pile hammer must correspond to the length and type of pile. Hammer number is the most important index for penetration velocity of impact piling method. Average driving force is a function of pile resistance and section area. For total resistance, AC refers to the actual section area of the pile. Average driving stress is the index of difficulty in piling, and the approximate guiding value is given.
