What Is a Silent Uninstall?

Uninstall (xiè zài, uninstall) refers to the operation of deleting program files and folders from the hard disk and deleting related data from the registry, freeing up the original disk space and making its software no longer exist in the system or deleting the corresponding Device driver and delete the registry information related to the device driver, and then remove the device from the physical device of the computer (generally the user updates the physical device of the computer to upgrade, if you do not remove the physical device, it usually means updating the device driver) .

The software does not just copy files to the system during the installation process, but also performs other operations.

such as:

Unloading point layout. According to the needs of the project, the supporting tire frame is arranged, the unloading point is determined by professionals, and the construction is strictly in accordance with the requirements.

Establish an unloading command. During the construction process, emergency accidents are unavoidable. In order to ensure the smooth unloading process, a serious and reliable headquarters should be established to clarify personal responsibility. Carefully check the condition of each support point. Observe whether the connection of each part is intact. ^[1]

During the hoisting process, the steel structure is supported by the supporting tire frame, and the vertical load generated by the structure's own weight is borne by the supporting tire frame. After lifting is completed, the load should be carried by the structural system, so an unloading step is performed.

The steel structure unloading is the process of changing from the construction state to the design stress state. During the unloading process, the supporting tire frame is dismantled, causing the structure to be displaced, and large stresses are instantaneously generated in the structural members. Therefore, the unloading scheme should be determined, and the hierarchical synchronous unloading should be selected to control the deformation of the structure, so that the stress changes and structural deformation can be allowed. Within this range, the safety of the structure is thus guaranteed. Both proportional synchronization and equidistant synchronization belong to hierarchical synchronization, and both can determine the unloading point drop stroke. According to the above unloading principles, the following methods are mainly used for unloading construction: sand box unloading method, screw jack unloading method and computer electronically controlled hydraulic jack unloading method.

The sand box unloading process is based on the principle of an hourglass, and the sand box is selected to be made into an unloading device. Due to the small compressibility of sand in a closed state, the pressure capacity of the sand box is guaranteed. The gate valve is used to control the sand flow rate, so that the load transfer is performed slowly, ensuring the stability of unloading and ensuring the safety of construction. The sand box is divided into two parts, the outer sleeve and the inner sleeve, the inner tube is sleeved inside the outer tube and directly contacts the structural rods; the outer tube is filled with sand, and the sand discharge valve switch is set on the side or bottom of the cylinder wall. Control the flow of grit. At the beginning of unloading, the gate is opened, and the sand body flows out to realize unloading. The diameter of the inner tube and the outer tube should be strictly controlled. If the distance is too small, it is easy to jam, and if the distance is too large, it is easy to spill sand. The diameter, wall thickness and material of the outer and inner cylinders of the flask should be calculated according to different stress conditions. ^[1]
