振动沉桩现场浇灌混凝土一般采用一吨卷扬机起吊料斗,再用人工将料斗内混凝土往桩管加料口卸料。这样操作比较麻烦,耗用人工多,且难以控制就位。我公司在试制十二吨轻型振动沉桩机的过程中,对上料系统进行了改进,仅由卷扬司机一人操作,即可自动上料、提升和卸料。 Vibrated pile driving concrete is usually lifted with a ton of hoisting machine to lift the hopper, and then the concrete in the hopper is discharged manually to the feeding port of the pile pipe. This operation is cumbersome, consumes much labor, and is difficult to control in place. In the process of trial production of a 12-ton light vibration pile driver, the company improved the loading system. It can be automatically loaded, lifted, and unloaded only by a single driver.
