- the three-cylinder hydraulic device is used to complete the steering's own positioning, because the three hydraulic cylinders are placed on the same horizontal plane, and the angle of each two cylinders is equal to 120. .
- the hydraulic cylinder was extruded, the horseshoe block was squeezed into the soil. Because the three cylinders worked at the same time, the positioning of the horseshoe was completed, and it also played a role of centering the body.
- I YA I I YC I is equal in size and opposite in direction. Because the B axis only has displacement in the X direction, that is, the expansion and expansion direction, such equipment uses B as the positioning to complete the expansion and expansion, so that the equipment neither floats nor sinks, thereby greatly reducing the sediment at the bottom of the hole. Since the piston sleeve and the piston rod are extruded simultaneously under the same oil pressure, and the areas of the piston rod and the piston sleeve are the same, the extrusion forces are equal. When retracted, the upper and lower cylinders are connected, the pressure is equal, but the areas are not the same. There was a slight difference in speed when coming back.
- the pull-type cylinder extruder is specially designed so that the movement trajectories of the three axes connected to the bow pressure arm are
- the overall expansion of the extruder Due to the displacement of point B in the Y direction, the overall expansion of the extruder has a displacement of Yi. If a 400-cylinder cylinder is used for expansion, a 200-300 ton expansion force is obtained. The compaction and expansion are carried out below, and the body moves downwards in the soil by 30-40 cm, so that the sediment at the bottom of the hole is compacted and compacted. Practice has proved that the compacted soil is about 30% larger than the original land bearing capacity. Therefore, the problem of sedimentation was solved during the process of supporting and expanding the plate.
- a pressure sensor is installed at a position of 0.618 on each bow pressing arm of the extruder. In this way, the pressure value at each moment can be obtained during the expansion and expansion process.
- the pressure change value with time is amplified by the single-chip AD converter into a digital signal, and the three curves are printed out by the integrator and the value of ⁇ F is displayed.
- the pressure situation of each arm can be well grasped, which can reflect not only the component force but also the combined force, in order to fully understand the soil layer and perform quality monitoring during construction.
- the main body model can be established in the microcomputer during the construction process, and the pressure value, the pressing angle value, the rotation angle value and the equipment on each arm can be known at any time.
- the depth value in the hole so that the bearing capacity of the pile can be known before pouring, which is an inspection of the survey, and it also solves the problem of difficult inspection of branch and pile piles, such as completion of expansion and expansion, but I do n’t know
- the quality of the completion can be expanded again at the same position. If there is no change in the pressure gauge, it means that the extrusion is completed well. If there is a change in the angle, then the hole collapse phenomenon will occur. Because of the neural brain, since the laptop computer is used for data processing when the power supply is insufficient, this can well control the construction quality and establish a data file for each pile, and obtain a better basis for future design.
