Cast-in-situ drainage channel structure of moldless construction roof

Abstract

The invention relates to the field of drainage construction, in particular to a cast-in-situ drainage channel structure of a moldless construction roof. The structure is characterized by comprising acushion layer and a bottom plate arranged above the cushion layer, wherein side plates are arranged at the two sides of the bottom plate, the bottom plate and the side plates are integrally poured tobe molded, the tops of the sides, close to the inner portions, of the side plates are provided with notches, the notches in the two side plates form a placing groove, a plurality of notch sealing plates are laid on the placing groove in the extending direction of the side plates, the height of the placing groove is larger than the thickness of the notch sealing plates, a roof body is poured abovethe notch sealing plates, a plurality of pre-embedded ribs are buried in the side plates in the extending direction of the side plates at intervals, and the top ends of the pre-embedded ribs are located in the roof body and bent; during the construction, the cushion layer is firstly poured, then the bottom plate and the side plates are poured on the cushion layer, the tops of the pre-embedded ribsare wrapped by the roof body to strengthen the connection strength between the roof body and the side plates, thereby not only ensuring the sealing performance of a drainage channel, but also solvingthe problem that a used bottom mold and support when the roof body is poured is difficult to dismantle, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the field of drainage construction, more specifically, it relates to a cast-in-place drainage channel structure with a formless construction roof. Background technique [0002] Modern urban diversion drainage systems are divided into sewage drainage systems and rainwater drainage systems, both of which are pressure-free systems. Sewage drainage systems are usually composed of pipes, and rainwater drainage systems are usually composed of pipes or drains. [0003] The second paragraph of Article 9.1.1 of the national standard "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering" 50268-2008 stipulates that the tightness test of the pipeline should be carried out for the non-pressure pipeline. However, there is no clear test requirement for the tightness of drains. With the frequent occurrence of extreme weather, many cities in China are frequently flooded. When flooding occurs, the rainwater syst...
