Drainage component with isolation reinforcer

Abstract

The invention discloses a drainage component with an isolation reinforcer and belongs to the field of drainage components for soft soil foundation construction. The filtering membrane layer of the existing structure easily falls into a drainage channel and is lacerated by the side wall (rack) of the drainage channel under lateral pressure. The drainage component comprises a plastic or synthetic resin core plate made with a plurality of longitudinal parallel drainage channels; and the core plate is externally coated with at least one filtering membrane layer. The drainage component is characterized in that the isolation reinforcer is arranged between the drainage channels and the filtering membrane layer, and has the advantage that the filtering membrane layer and the core plate are firmly connected and the advantage that the filtering membrane layer does not easily collapse, fall or crack.

Description

【Technical field】 [0001] The invention relates to an improved drainage component with isolation reinforcements, and belongs to the technical field of drainage components for soft soil foundation construction. 【Background technique】 [0002] Soft soil foundation with high water content cannot meet the requirements of civil construction. In the prior art, a plate-shaped drainage member is often inserted into the foundation to drain the water contained in the foundation. The usual plate-shaped drainage member is a core plate made of plastic or synthetic resin with longitudinal drainage channels composed of multiple grooves on one or both sides. The cloth filter membrane layer is widely used in the drainage construction of the soft foundation silt soil drainage consolidation process in engineering construction. [0003] Under the condition that the plate-shaped drainage components are used in the vertical direction in the deep soft foundation within 50 meters, due to the downw...

Problems solved by technology

In addition, in order to maximize the space of the drainage channel, the side wall is rack-shaped, and the top surface area of ​​the side wall is small or sharp. The strength of the adhesive connection between the filter membrane layer and the top surface of the side wall is low. It is easy to separate under the action, and the filter membrane layer will be cut by the side wall due to the lateral pressure, so that the sludge will enter the drainage channel and cause blockage, so that the filter membrane layer of the drainage component loses the function and function of separating soil

Furthermore, when the rack-shaped side wall is bent laterally, it is relatively soft and not stiff enough. When it is bent longitudinally, the drainage channel at the crease is prone to breakage. If there is lateral distortion during construction and use, it will also make the drainage channel The space is getting smaller, which affects the water flow performance and the normal use of the product

To achieve sufficient stiffness, it is necessary to produce a thicker material structure and use more materials, resulting in a significant increase in production costs
