Widened embankment slope foundation reinforcing system and method

Abstract

The invention discloses a widened embankment slope foundation reinforcing system which is mounted on an original inclined embankment and comprises an embankment base, a widened embankment, rigid piles, in-embankment piles and a new pavement structure. The rigid piles are mounted on one side, away from the original embankment, of the embankment base in an inserted manner, the widened embankment isarranged between the new pavement structure and the rigid piles, one side of the widened embankment is fitted with the original embankment, and the in-embankment piles are mounted between the new pavement structure and the original embankment, sequentially penetrate the widened embankment and the original embankment and are connected with the embankment base. The rigid piles are mounted on one side, away from the original embankment, of the embankment base in an inserted manner and utilized to improve strength of a newly-built embankment base, so that convenience is brought to subsequent reinforcing work; the widened embankment and the original embankment are reinforced through the in-embankment piles which can be built on original rigid piles, so that strength is improved; excavation of aslope during construction of rigid piles and pile caps on an original embankment slope is avoided, so that construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a system and method for strengthening the foundation of a widened embankment slope. Background technique [0002] With the rapid development of the economy, the growth rate of traffic volume in developed areas is almost double digits. Many expressways have insufficient traffic capacity and service levels shortly after their completion, and urgently need to be rebuilt and expanded. Moreover, the newly built highway network in the early stage has a prominent position and basically belongs to the traffic arteries in economically developed areas, so the problem of expansion and capacity expansion is particularly prominent. [0003] At present, my country has begun to widen and reconstruct trunk roads. In order to reduce the differential settlement between the existing embankment and the widened embankment and avoid longitudinal cracks, the widened embankment is usually trea...

AI Technical Summary

Problems solved by technology

Therefore, the rigid piles, pile caps, and embankment soil need to be constructed in multiple times, and the corresponding construction machinery and personnel need to enter and exit the site many times, which prolongs the construction period and increases the cost.

In addition, the construction of rigid piles and pile caps on the slope needs to excavate the existing edge break, which will also have a negative impact on the stability of the existing slope
