Description

Technical Field

[0001] The present application relates to the field of wall-penetrating pipes, and in particular to a pre-buried sleeve device capable of fine-tuning the position of a pipeline. Background Art

[0002] Wall bushing is also called wall tube, waterproof bushing, wall embedded tube. Waterproof bushing is divided into rigid waterproof bushing and flexible waterproof bushing. The one used for conduction in electricity is called AC wall bushing. It can be divided into dry capacitor type AC wall bushing and porcelain insulation AC wall bushing according to the material, which are referred to as silicone rubber bushing and porcelain bushing respectively.

[0003] Conventional pre-buried casing is easy to deviate from the position. The pre-buried casing is rigidly connected to the concrete and cannot be moved. The casing must be chiseled out and the concrete must be poured again to install the casing. The chiseled out position is very prone to water leakage later. Even if the casing deviates from a small position and the working pipe barely passes through the casing, since the casing cannot be adjusted, the gap between the working pipe and the casing is eccentric and not sealed tightly later, leakage is inevitable.
