Waterproof construction method for external corner of bottom plate of urban underground comprehensive pipe gallery

Abstract

The invention discloses a waterproof construction method for an external corner of a bottom plate of an urban underground comprehensive pipe gallery. The waterproof construction method comprises the steps that S1, a bottom plate waterproof structure is smeared; S2, a silicone oil paper layer is laid; S3, a mortar isolation layer is smeared; S4, a bottom plate protection layer is poured, and main body construction is conducted; S5, a part of the mortar isolation layer is removed, and the chamfers are flattened; S6, an outer waterproof layer and a waterproof reinforcing layer are smeared; and S7, a waterproof protection layer on the outer side of the bottom plate is poured, and a side wall protection layer is pasted. According to the waterproof construction method, the silicone oil paper layer and the mortar isolation layer are laid between the bottom plate waterproof structure and the bottom plate protection layer, by means of the combined structure of the silicone oil paper layer and the mortar isolation layer, after bottom waterproof construction of the underground comprehensive pipe gallery base layer is completed, in the construction process of a main body structure, the bottom plate waterproof layer at the lap joint part of the bottom plate external corner is protected and is not damaged in the main body construction process, and the waterproof quality of the bottom plate external corner is ensured.

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 bottom plate of an urban underground comprehensive pipe gallery. Background technique [0002] With the continuous acceleration of urbanization in our country, the construction of urban underground comprehensive pipe gallery has gradually become the main development trend in the process of overall urban construction. In the process of construction of urban underground comprehensive pipe gallery, 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 laying a good foundation for the construction of the underground comprehensive pipe gallery. The waterproof joint of the sun corner of the bottom plate of the pipe gallery is also the weak part of the waterproof of the...

AI Technical Summary

Problems solved by technology

The construction cost and construction period of the traditional construction structure at the external corner of the bottom plate will increase accordingly due to the need to build a protective wall; the waterproof structure without a protective wall will often cause damage to the main body of the urban underground comprehensive pipe gallery during the construction process
