Embodiment Construction

[0041] like Figure 1 to Figure 6 As shown, the present invention comprises the following steps:

[0042]Step 1. Apply the bottom plate waterproof structure: apply the bottom plate waterproof structure on the top of the cushion of the main structure 10 of the pipe gallery to be constructed; wherein, the width of the bottom plate waterproof structure is larger than the width of the main structure 10 of the pipe gallery, and the bottom plate The waterproof structure is applied from low to high along the longitudinal extension direction of the main structure 10 of the pipe gallery;

[0043] like figure 1 As shown in the figure, step 2, laying a silicone oil paper layer: laying a silicone oil paper layer 3 on the top of the base plate waterproof structure that has been laid; wherein, the silicone oil paper layer 3 is along the longitudinal extension direction of the base plate waterproof structure, from low to low Lay it up; the bottom of the silicone oil paper layer 3 is in clo...

Abstract

The invention discloses a waterproof construction method for the outer corner of the bottom plate of an urban underground comprehensive pipe gallery. The method comprises the following steps: first, applying a waterproof structure to the bottom plate; step two, laying a silicone oil paper layer; step three, applying a mortar isolation layer; And carry out the main construction; step 5, remove part of the mortar isolation layer and smooth the chamfer; step 6, apply the outer waterproof layer and waterproof reinforcement layer; step 7, pour the outer waterproof protective layer of the bottom plate and paste the side wall protective layer. In the present invention, a silicone oil paper layer and a mortar isolation layer are laid between the bottom plate waterproof structure and the bottom plate protective layer, and the combined structure of the silicone oil paper layer and the mortar isolation layer is used to complete the bottom waterproof construction of the base of the underground comprehensive pipe gallery. Then, in the construction process of the main structure, the base plate waterproof layer at the lap joint of the base plate's outer corner is protected from damage during the main body construction process, which ensures the waterproof quality of the base plate's outer corner.

Description

technical field [0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery construction, and in particular relates to a waterproof construction method for the outer corner of the bottom plate of an urban underground comprehensive pipe gallery. Background technique [0002] With the continuous acceleration of urbanization in my country, the construction of urban underground comprehensive pipe corridors has gradually become the main development trend in the process of overall urban construction. In the construction of urban underground comprehensive pipe corridors, the application of waterproof construction technology It is very important to do a good job in the basic waterproof construction work, which is an important foundation for the construction of the underground comprehensive pipe gallery. The waterproof lap joint of the outer corner of the pipe gallery bottom plate is the weak part of the pipe gallery waterproof, which has an imp...
