Problems solved by technology

[0005] 1. Although the biodegradable flowerpot has air permeability and water permeability, the ultra-soft foundation and tailings pond have large water content and a lot of fine-grained mud. If the conventional soil material is used, the flowerpot is easy to expand and deform under the pressure of the side wall, and the micropores of the basin wall are rapid Clogged with tiny particles and uncontrollable rate of material degradation
[0006] 2. Air leakage, which cannot meet the needs of degradable flower pots for ultra-soft foundation or tailings pond pumping, water seepage, salt washing, and gas pumping.
[0007] 3. The problem of auxiliary nutrients required for greening and the root system is easy to penetrate the flower pot and enter the foundation are not taken into account
[0008] 4. After the flowerpot is degraded, when the conventional planting soil and soilless planting soil meet the ultra-soft foundation or the tailings pond is soaked in water, they will be compacted by side pressure and mud will enter, causing the root system of the early-fed plants to be damaged and easy to die

Embodiment 1

[0043] Take 15 parts of modified urea-formaldehyde resin, 40 parts of bagasse, 15 parts of palm silk, and 30 parts of straw coarse paper pulp (unbleached), fully mix the raw materials on a mixer, and mold and solidify at 105-140 ° C. The thickness of the cylinder wall is 1 cm, the diameter of the cylinder is 20 cm, and the total length is 60 cm, of which the lower 30 cm long part is tapered. The mouth of the tube is brushed with linseed oil; the outer layer of the tube is coated with chitin as glue and steel slag powder about 0.3 mm thick; the inside of the tube is sprayed with compound bacteria, and the finished product is dried in the sun.

[0044] Put the blast furnace slag into the soilless cultivation material and insert it into the riverside silt, which can effectively infiltrate the percolation water in the silt for a long period of time. The upper casing can pump air to the sludge. The plant planting experiment shows that the survival rate and root system weight of th...

Embodiment 2

[0047] Take 10 parts of modified urea-formaldehyde resin, 50 parts of bagasse, 20 parts of palm silk, and 20 parts of straw coarse paper pulp (unbleached). The raw materials are fully mixed on a mixer, and molded and solidified at 105-140 ° C. The thickness of the cylinder wall is 1.2 cm, the diameter of the cylinder is 15 cm, and the total length is 100 cm, of which the lower 30 cm long part is tapered. The mouth of the cylinder is brushed with hot-melt ceresin oil; the outer layer of the cylinder is made of chitin as glue and brushed with magnesium oxide powder about 0.5 mm thick; the inside of the cylinder is sprayed with compound bacteria, and dried in the sun to obtain the finished product.

[0048] The small-scale dredged sludge dump was used as the test, and the dredged sludge dump was directly used as a conversion ditch. The steel slag bag wall on the outside of the dump was used as a water seepage cofferdam, and the outer layer was made of ecological concrete protectio...

Abstract

The invention discloses a degradable planting filler cylinder for a super soft foundation or a tailing pond and a manufacturing method. The cylinder is prepared by uniformly mixing plant elastic longfibers, degradable permeable fibers and degradable plastics, a mold is used for heat solid to form an initial blank, the initial blank is impregnated with a plant hormone, the outer layer of the initial blank is coated with minerals, the initial blank is internally filled with a skeleton supporting material and a planting material, and a degradable sealing material is sprayed on a barrel of a mouth of the initial blank. A filler cylinder column forms an elastic skeleton fiber-non-elastic filter fiber staggered microstructure, which can ensure the intercepting ability, permeability and elasticshape-retaining ability of the main structure to fine mud particles, and meet the requirements of the degradable filtration planting filler cylinder for greening of the super soft foundation or the tailing pond.

Description

technical field [0001] The invention relates to the technical field of degradable composite materials, in particular to a degradable planting packing tube used for ultra-soft foundations or tailing ponds and a manufacturing method. Background technique [0002] Ultra-soft ground and tailings ponds lack good air permeability, and often contain more harmful gas, liquid, and solid components. It is generally impossible to directly green seedlings without pretreatment. A reasonable idea is to prefabricate a superior The niche is used for the transitional growth of green plants, and the micro-habitat can be used to control the ultra-soft foundation and the tailing pond. [0003] Traditional biodegradable flower pots have formed a series of achievements and are commonly used in the market. Among them, the most advantageous in sales are the flower pots that use urea-formaldehyde resin, soybean protein modified urea-formaldehyde resin, etc., and pulp, straw powder, and various mixtu...
