Collaborative Utilization Method of Construction Waste in Mountain Landscaping Project

Abstract

The invention discloses a method for synergistic utilization of construction waste in mountain landscaping projects, including: regenerated coarse aggregate is used for gravel piles, engineering dregs is used for mountain piles, regenerated fine aggregate is used for horizontal drainage layers, and large particle size Waste rocks are used for backpressure layer at the slope toe, pre-screened muck and recycled fine aggregate are used as capping and covering layer. The present invention gives full play to the engineering characteristics of different types of construction waste, and uses them in different parts of the mountain landscaping project to solve the problems of stability, safety and water and soil conservation in the mountain landscaping project in southern my country, including: 1) the large load of the mountain body is easy to cause Problems of soft soil foundation instability and differential settlement, 2) slow drainage and consolidation of high-moisture engineering dregs can easily cause problems such as landslides in piles; 3) problems such as rainwater infiltration causing softening of piles of fill and erosion of vegetation layers by rainwater. Through the technical scheme of the invention, the piles of engineering dregs in southern my country can be piled high and stable, and at the same time, outlets can be provided for five types of construction wastes.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for synergistic utilization of construction waste in mountain landscaping projects. Background technique [0002] At present, my country is in the stage of rapid urbanization, and the large-scale development and construction of underground spaces in various cities has produced a large amount of construction waste. Construction waste refers to all kinds of solid waste generated during the construction, renovation, decoration, demolition and laying of various buildings and structures and their auxiliary facilities, mainly including engineering dregs, engineering mud, engineering waste, demolition Garbage and decoration waste five categories. Engineering slag refers to the spoil produced by excavating earth and stone during the construction process of various buildings (structures), pipe networks, roads and bridges. Engineering waste refers to the waste m...

AI Technical Summary

Problems solved by technology

[0003] A large amount of construction waste in our country is randomly discarded or simply landfilled. This extensive disposal method not only occupies a large amount of land, but also easily causes safety hazards and environmental pollution.

The following characteristics exist in the coastal areas along the river in southern my country when using engineering dregs for mountain landscaping: 1) The natural foundation is mostly soft soil foundation, which is difficult to bear the huge and unevenly distributed load of the piled mountain, and is prone to shear failure of the foundation soil, uneven Excessive uniform settlement and other issues; 2) Engineering muck has the characteristics of high moisture content, low shear strength, slow drainage and consolidation, which are easy to induce local collapse and overall slippage of the pile mountain; 3) Most of them are in humid climate areas, There is plenty of rain all year round, so it is easy to have problems such as rainwater erosion causing mountain soil erosion, rainwater infiltration and filling soil softening, etc.
