A pile-supported reinforced embankment based on waste tires and its working method

Abstract

The invention discloses a pile-supported reinforced embankment based on waste tires, which includes several rigid piles, the lower end of each rigid pile is inserted into the soft soil foundation, the upper end of the rigid piles is nested with waste tires, and the lower end of the rigid piles is inserted into the soft ground. The lower end of the waste tire wraps the side wall of the rigid pile, and the upper waste tire is stacked on the upper end of the lower waste tire, and concrete is poured inside the upper waste tire and the lower waste tire, so that the upper waste tire, the lower waste tire and the rigid pile are firmly connected In one piece, drainage filler is arranged between the upper waste tire and the lower waste tire on adjacent rigid piles, and mixed filler is laid above the upper waste tire. The invention helps to quickly form a pile-soil settlement difference in the area near the pile top under the action of the overlying load, and then quickly exerts the soil arch effect and the reinforcement effect, and quickly exerts the high load-bearing characteristics of the rigid pile, and the subgrade has good water permeability, which is convenient The dissipation of excess static pore water pressure during construction is beneficial to foundation stability during construction.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering foundation treatment, and in particular relates to a pile-supported reinforced embankment based on waste tires and a working method thereof. Background technique [0002] Proper disposal of waste is related to the sustainable development of society and is a key link in the field of environmental protection. Scrap tires are called "black pollution". The output of waste tires in my country is huge, and it is increasing year by year. The ensuing environmental pollution problems are also becoming more and more serious. At present, the commonly used waste tire treatment methods include incineration, retreading, secondary treatment and reuse, etc., but compared with the output of waste tires, the overall utilization rate is still low, and the pressure on environmental protection remains high. [0003] Pile-supported reinforced embankments are widely used in soft soil foundation treatme...

AI Technical Summary

Problems solved by technology

The differential settlement of pile-soil in the area near the pile top is an important prerequisite for the pile-supported reinforced embankment to exert the "soil arch effect" and "reinforcement effect". A sufficient amount of pile-soil differential settlement is produced, and the pile-supported reinforced embankment has the following disadvantages: (1) The utilization rate of the rigid pile bearing capacity in the initial stage of embankment filling is low, and the embankment filling period is long; (2) The total pile-soil differential settlement The amount is too small, the soil arch effect and reinforcement effect are not fully exerted, and the high load-bearing characteristics of rigid piles are not fully exerted
