Drainage belt, an industrial product, is a commonly used soft foundation treatment material Drainage strip is the abbreviation for plastic drainage strip, which is commonly referred to as plastic drainage board and is a commonly used material for soft foundation treatment

Appearance of drainage belt product:

1. Packaging appearance: It adopts a central winding to form a circular cake shape, with a diameter of about 0.8M~1.3M and a height of 0.1M.

2. Section: The core plate is a parallel cross shaped structure, forming a harmonica shape

Material used for drainage belt:

1. The core board is mixed with polypropylene (PP) and polyethylene (PE), which has both polypropylene and rigidity, as well as the flexibility and weather resistance of polyethylene.

2. The filter membrane adopts long fiber hot rolled non-woven fabric, which has water immersion resistance and excellent water permeability 3. When the filter membrane is wrapped in a composite core plate, the ultrasonic vibration method is used to firmly integrate the filter membrane

Working principle of drainage belt:

The plastic drainage belt is inserted into the soft soil foundation using a board inserting machine. Under the action of the upper preloading load, the gap water in the soft soil foundation is discharged from the plastic drainage belt to the sand layer or horizontal plastic drainage pipe laid on the upper part, and discharged from other places to accelerate the consolidation of the soft foundation.

. In the treatment of soft soil foundation, the function design and construction equipment of the drainage belt are basically the same as those of the sand bag well
