Problems solved by technology

[0002] Hydropower energy and various industrial plants often encounter pipelines that need to pass through the inner or outer walls of buildings. It is a common practice to use wall-piercing casing technology to solve the problem of pipeline penetration and waterproofing. However, in actual engineering, these wall-piercing casings Due to the complicated construction, the waterproof performance cannot be guaranteed, resulting in waterproof failure

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below through specific examples.

[0022] Such as figure 1 As shown, a wall-piercing sleeve with high waterproof performance that is easy to construct includes a sleeve 1 and a hollow wing ring 5. The sleeve 1 is provided with a hollow cavity for the penetrating tube 2 to pass through. On the outer wall, the gap between the contact surfaces at the two ends of the casing 1 and the through-pipe 2 is sealed with an inflatable sealing ring;

[0023] The inner cavity of the hollow wing ring 5 communicates with the hollow cavity, and the hollow wing ring 5 is connected with a grouting device 6 and an exhaust device 4. The grouting device 6 and the exhaust device 4 are distributed near the pipe 2 and penetrate a On the hollow wing ring 5 on the side, the number of grouting devices 6 and exhaust devices 4 is 1-4, and the grouting devices 6 and exhaust devices 4 are evenly distributed on the hollow wing ...

Abstract

The invention provides a high-waterproofness wall bushing easy to construct. The wall bushing comprises a bushing body and a hollow wing ring. The bushing body is provided with a hollow cavity allowing a penetrating pipe to penetrate out, and the outer wall of the bushing body is sleeved with the hollow wing ring. An inner cavity of the hollow wing ring communicates with the hollow cavity, and thehollow wing ring is provided with a grouting device and an exhaust device in a communicating manner. The high-waterproofness wall bushing easy to construct has the beneficial effects that the outer side seepage path of the bushing body is additionally arranged, the waterproofness of the inner side of the bushing body is enhanced through grouting, a grouting manner is used for replacing asbestos cement, sealant, batched jute filling and beating and other tedious waterproof work, and high waterproof performance is guaranteed while operation is simplified.

Description

technical field [0001] The invention relates to the technical field of construction of a waterproof wall-piercing sleeve, in particular to an easy-to-construct wall-piercing sleeve with high waterproof performance. Background technique [0002] Hydropower energy and various industrial plants often encounter pipelines that need to pass through the inner or outer walls of buildings. It is currently a common practice to use wall-piercing sleeve technology to solve the problem of pipeline penetration and waterproofing. However, in actual engineering, these wall-piercing sleeves Due to the complicated construction, the waterproof performance of the concrete can not be guaranteed, resulting in waterproof failure. The high waterproof performance wall casing technology that is easy to construct is in urgent demand for such projects. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides an easy-to-construct wall-piercing casing w...
