Problems solved by technology

Most cities in my country still adopt the traditional green space development and management model, and the phenomenon of wasting water is serious
Firstly, the green land irrigation facilities and management level are poor, the utilization rate of irrigation water is low, water-saving irrigation methods such as sprinkler irrigation and micro-irrigation are not widely used, and artificial water pipes or water trucks are still used for irrigation; secondly, the plant configuration is unreasonable, and the lawn The use of drought-tolerant grass species and native grass species in the green space is less, which increases the water demand for irrigation; finally, the application of natural precipitation and recycled water is seriously insufficient

example 1

[0055] Example 1. When the mass percentage of aggregates of various particle sizes in the graded construction waste mixture is as follows:

[0056]

[0057] The proportion of each component in the pouring mixture is as follows, cement: fine sand: graded construction waste mixture: water retaining agent: bentonite: water = 1:2:7:0.063:0.031:0.4, the water storage bricks produced are more Pores, pore spacing is appropriate, forming a lot of water storage pockets that can store water, good water absorption, good water permeability, good compressive strength, and good water storage function.

example 2

[0058] Example 2. When the mass percentage of aggregates of various particle sizes in the graded construction waste mixture is as follows:

[0059]

[0060] The proportions of each component in the pouring mixture are as follows, cement: fine sand: graded construction waste mixture: water retaining agent: bentonite: water = 1:3:8:0.063:0.011:0.3, compared with Example 1, the production The produced water storage bricks have high water absorption, poor water permeability, low compressive strength, and poor water storage performance.

example 3

[0061] Example 3. When the mass percentage of aggregates of various particle sizes in the graded construction waste mixture is as follows:

[0062]

[0063] The proportions of each component in the pouring mixture are as follows, cement: fine sand: graded construction waste mixture: water retaining agent: bentonite: water = 1:3:8:0.063:0.011:0.3, compared with Example 1, the production The produced water storage bricks have low water absorption, high water permeability, low compressive strength, and poor water storage performance. The water storage bricks made by the method of the present invention can be applied in the field of lawn laying. When in application, one or more layers of water storage bricks are laid first, and then lawns are planted on the water storage bricks. The following two methods can be used for planting: methods:

[0064] 1) Spread 3cm to 5cm of planting soil on the water storage bricks, and spread turf rolls on the planting soil;

[0065] 2) Spread ...

Abstract

The invention discloses a method of manufacturing a water storage brick by utilizing building garbage. The method comprises the following steps: carrying out treatments of crushing and sorting on the building garbage to acquire aggregates in different particle sizes; mixing the aggregates in different particle sizes according to a preset gradation to form a graded building garbage mixture; adding cement, fine sands, a water retaining agent, bentonite and water in the graded building garbage mixture, and uniformly mixing to form a grouted mixture; grouting the grouted mixture into a prefabricated die for manufacturing the water storage brick, and carrying out profiling treatment to form a green water storage brick; and curing the green water storage brick to form the water storage brick. By adopting the method provided by the invention, the building garbage is manufactured into the water storage brick with the water permeability, the water retention performance and the water absorption performance and is used for turf greening, so that waste is turned into wealth, the environment is protected, automatic water storage and water retention can also realized, the manual watering cost is lowered, and the method makes a contribution to transformation into a water-saving landscape.

Description

technical field [0001] The invention relates to the ecological restoration field of absorbing, accumulating and utilizing natural underground water resources in arid areas for vegetation restoration, in particular to a water storage brick made based on construction waste and its application in lawn laying. Background technique [0002] At present, tap water is mostly used as the source of irrigation water for urban green spaces in my country. The expansion of green areas has led to an increase in irrigation water consumption, which has brought new pressure on urban water supply. Most cities in my country still adopt the traditional green space development and management model, and the phenomenon of wasting water is serious. Firstly, the green land irrigation facilities and management level are poor, the utilization rate of irrigation water is low, water-saving irrigation methods such as sprinkler irrigation and micro-irrigation are not widely used, and artificial water pipes...
