Embodiment 2

[0020] In Embodiment 2 of the present invention, a waterproof method for pipelines passing through settlement joints of hydraulic structures, which specifically includes the following steps:

[0021] 1) Install a rigid waterproof casing 4 in the wall 2 on one side of the settlement joint 1 along the axis of the rigid wall-penetrating pipe 3;

[0022] 2) Install the rigid wall-penetrating pipe 3, and fill in linoleum 5 and asbestos cement 6; Asbestos cement 6 is filled and compacted. The mix ratio of asbestos cement 6 must meet the specification requirements, and it must be stirred evenly. It should be used up before the initial setting. The waterproof casing used for drinking water pools should also be filled with sealing paste;

[0023] 3) Install the rigid waterproof casing 8 in the wall 7 on the other side of the settlement joint 1 along the axial direction of the rigid wall-penetrating pipe 3. In this step, it is necessary to make a budget for the final differential settle...

Abstract

The invention discloses a waterproof method for a pipeline passing through a settlement joint of a hydraulic structure, which specifically includes installing a rigid waterproof casing, a rigid wall-penetrating pipeline, and filling with linseed and asbestos cement. The invention adopts a rigid-flexible combination connection The method takes into account the waterproof problem between the wall-penetrating pipe and the wall to be penetrated and eliminates the damage to the structure due to uneven settlement. It has the characteristics of good waterproof effect, convenient construction and maintenance, and strong applicability.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a waterproof method for pipelines passing through settlement joints of hydraulic structures. Background technique [0002] At present, land resources are extremely precious due to large-scale urban construction, and saving engineering land has become a trend. In order to save engineering land, a large number of structures with greatly different structures, functions, and loads are closely connected together. When the heights, loads, and structural forms of adjacent structures are greatly different and the foundation is weak, the structures may be uneven. Subsidence, causing some parts to crack. For this reason, settlement joints should be set at appropriate positions such as complex plane or shape turning points, height changes, loads, foundation compressibility and foundation treatment methods are obviously different. [0003] When rigid pipelines pass through these settle...
