Problems solved by technology

Low-strength plain concrete piles and cement-soil piles are used in the treatment of foundations. Due to the joint action of piles and soil, the force on the pile body is small, so the compressive strength of the concrete required for the pile body is low.

Abstract

The invention discloses a construction waste regenerated aggregate concrete pile and a soil foundation treatment method thereof. The construction waste regenerated aggregate concrete pile is mainly prepared by cement, construction waste rough aggregate and construction waste fine aggregate. The preparation method includes technological steps of smashing, screening, mixing, drilling and pile forming and the like. The construction waste regenerated aggregate concrete pile has the advantages that the problem that most construction waste cannot be used sufficiently is solved, the concrete pile can be widely applied to construction projects of railways, roads and houses and the like, the soil foundation of buildings treated by the method is high in bearing capacity and small in deformation, and further, treatment and manufacturing cost is low, cost is saved, effective utilization rate of waste is increased and economical benefits are realized.

Description

technical field [0001] The invention relates to a building foundation, in particular to a construction waste recycled aggregate plain concrete pile and a foundation treatment method thereof, belonging to the field of building foundations. Background technique [0002] With the improvement of the national economy and the development of industrialization, many buildings need to be demolished and rebuilt every year due to the problems of the original buildings in terms of function, age and rational use of land materials, and more and more construction waste will be generated. At present, the amount of construction waste in my country has accounted for about 40% of urban waste, and the pollution caused by construction waste is equivalent to twice that of automobile exhaust. The hazards caused by construction waste have been fully paid attention to by all walks of life. However, the construction waste produced by buildings is different in composition and content, so it needs to ...
