driving method. The characteristics of the pile are mainly to bear the increased load, strong durability, high construction speed and great influence on the surrounding environment. There are three main types of pressure conditions. On the methods and characteristics of precast piles, please see below decomposition. Method of pile precast pile, precast pile pile by hammering, vibration, pressure into three kinds of methods are as follows: 1, hammer: hammer method is to use hammer impact energy to
overcome the resistance of soil to pile the pile to a predetermined depth. 2, vibration method: vibration method is the use of a highpower electric vibrator (vibration hammer), pile, the vibration hammer installed at the top of the pile, the vibration force to reduce the resistance of soil to pile, pile into the soil can make fast. 3, pressure pile method: pressure pile pile with pile frame weight and pressure on the pile frame, through the pile buried in reversing pulley. The contents of the above are based on the actual work of
the students to meet the problem of finishing, for reference, if there is a problem, please timely communication. Two, the precast pile can bear larger load, durable, fast construction speed, the weight of large precast pile three, the impact of the surrounding environment, according to the 1 test results to determine the pile end pressure standard. The 2 and final pressing times should be determined according to the length of the pile and address conditions for continuous complex, the depth is greater than or equal to
