Problems solved by technology

[0003] However, the existing plastic drainage boards are not degradable after being inserted into the ground, which will pollute the environment. If they are taken out and recycled after use, it will take time and labor and greatly increase the construction cost. However, the plastic drainage boards are always underground, which is easy to cause Post-construction settlement

Abstract

The invention provides a degradable drainage board, a material compound and a preparation technology, and belongs to the technical field of drainage boards. A degradable board body is prepared from, by weight, 65-75% of plant fibers and 25-35% of a solid bonding agent, the degradable board body is coated with a layer of a degradable filter net, and therefore the degradable drainage board can be obtained. The degradable drainage board has the advantages that the obtaining of raw materials is easy, the cost is low, the preparation method is simple, the implementation is easy, the prepared drainage board is degradable, the degraded drainage board loses a drainage function, so that a post construction foundation does not sink, and the environmental-protection and energy-saving performance is good.

Description

technical field [0001] The invention belongs to the technical field of drainage boards, and in particular relates to a degradable drainage board, a material composition and a preparation process thereof. Background technique [0002] Existing drainage boards are all plastic drainage boards (such as figure 1 ), the main structure includes a plate body and a filter screen 3 covering the outside of the plate body. In order to improve the structural strength of the plate body and improve the smoothness of drainage, the plate body usually includes a middle plate 1 and support plates 2 located on both sides of the middle plate 1 . Insert the drainage board into the soft soil foundation with a plugging machine. Under the action of the upper preload, the interstitial water in the soft soil foundation will be discharged from the plastic drainage board to the upper sand layer or horizontal plastic drainage pipe, and then discharged from other places. It can accelerate the consolidat...
