Embodiment Construction

[0026] The method for increasing the infiltration rate of rainfall runoff and increasing the storage capacity of soil is characterized in that it includes the following steps:

[0027] Such as figure 1 As shown, the first step is to make hollow straw rods, and the size of the hollow rods can be made on demand. For example, the length is 100mm-1000mm, the outer diameter is 30mm-300mm, and the wall thickness is 10mm-50mm. During the production process of straw hollow rods, turfgrass seeds are added to straw raw materials according to the ratio of 1:100 to 1000 between grass seeds and straw, and stirred and mixed to shape without drying;

[0028] Such as image 3 As shown, in the second step, in the seepage area such as lawn ground, use a special drilling machine to drill vertical holes according to a certain ratio. The hole diameter and hole distance can be set according to the needs of aesthetic design and soil quality. The hole diameter is 30mm~100mm; the hole depth is 300mm...

Abstract

The invention provides a method for increasing the rainfall runoff infiltration rate and the soil mass storage amount and belongs to the technical field of sponge cities. The aims of natural storage,permeation and purification of rainwater in a city area are mainly achieved. The method comprises the three steps that firstly, straw hollow bars different in size are manufactured according to demands, grass weeds of lawn are added to straw raw materials with the proportion of the grass weeds to straw as 1:(100-1,000), and the mixture is stirred, mixed and formed and does need to be dried; secondly, perforation is conducted at a water penetration area, and perforation is conducted at a lawn ground water penetration area and a field laid with water penetration bricks separately; thirdly, the straw hollow bars manufactured in the first step are inserted, then the peripheries of the straw hollow bars are filled with soil, and the cneters of the straw hollow bars are filled with water throughwatering. The infiltration runoff can have a high filter and purification effect, and the straw hollow bars have the advantages of being environmentally friendly and degradable.

Description

technical field [0001] The invention belongs to the technical field of urban sponging, and in particular relates to a method for increasing the infiltration rate of rainfall runoff and increasing the storage volume of soil by using straw hollow rods. Background technique [0002] In view of the fact that the ground in the current urban construction in our country has been solidified, the amount of rainfall runoff has increased significantly, the drainage is not smooth, and there are often practical problems caused by accumulated water. [0003] The General Office of the State Council issued the "Guiding Opinions on Promoting the Construction of Sponge City" in October 2015, pointing out that the construction of a sponge city should coordinate the use of natural ecological functions and artificial intervention functions, effectively control rainwater runoff, and achieve natural accumulation, natural infiltration, and natural purification. The development mode is conducive to ...
