Foundation drainage system of wooden structure house

Abstract

The present invention relates to building drainage system, and is especially foundation drainage system for timber structure building. The foundation drainage system includes basement wall bed, porous plastic apron pipes in basement wall bed, roof drainage pipe and sewer pipeline connected together. The present invention has double layer water draining mode including water draining pipe and porous plastic apron pipes, the separate draining of the roof water flow and the underground water flow and greatly raised water draining capacity to ensure the moisture proofing and ventilation of timber structure building.

Description

technical field [0001] The invention relates to a drainage system of a house, in particular to a drainage system for a foundation of a wooden structure house. Background technique [0002] Wooden structure houses are houses with wood as the main building material, and wood is easy to rot in a humid and closed environment, thus affecting the stability of the wooden structure house structure. Usually, a wooden structure house is generally built with a basement designed with ventilation, and then the main structure is built layer by layer on the basis of the basement. In most areas where wooden houses are built, foundation drainage must be done. Under normal circumstances, the water source of foundation drainage mainly includes two parts: one is rainwater and snow water from the eaves; the other is surface water and groundwater. [0003] The foundation drainage system of traditional wooden houses uses porous plastic drainage pipes for drainage. Coarse aggregate 3 is laid on ...

AI Technical Summary

Problems solved by technology

The existing foundation drainage system of this wooden structure house has the following disadvantages: ① rain and snow water from the eaves, surface water, and groundwater share a porous plastic drainage pipe. When the rain and snow water increases, the water flow will flow from the porous The plastic drainage pipe seeps back into the ground, and the drainage effect is poor

② The structural form of porous plastic drainage pipes is of great significance to the drainage of groundwater, but currently there is no porous plastic drainage pipe specially designed for wooden structures, and the existing porous plastic drainage pipes have poor drainage effect

③ Porous plastic drainage pipes are only laid with coarse aggregate, which is not conducive to the gradual infiltration of rain and snow water, surface water, and groundwater, which affects the drainage effect
