Method for constructing abrupt slope high embankment structure

Abstract

The invention discloses a method for constructing an abrupt slope high embankment structure. The method comprises the following steps of: A, cutting a slope in a line direction on an abrupt slope foundation to form a foundation platform, and excavating pile pits on the foundation platform at intervals; B, burying the pile foundation in the pile pits, and then installing longitudinal beams on the foundation platform in the line direction; C, placing T-shaped components on the longitudinal beams at intervals in the line direction, wherein each T-shaped component comprises a stand column and a triangular rib plate; and D, enabling the inner sides of the adjacent stand columns to be in lap joint with breast boards on the longitudinal beams in the line direction, and then filling the two sidesof the triangular rib plates and the inner sides of the breast boards with compacted embankment filling soil till the embankment face is reached. The embankment retaining structure is arranged on thebasis of being composed of the pile foundations and the longitudinal beams, soil pressure acting on the soil retaining plates is balanced through friction force between the triangular rib plates on the T-shaped components and embankment filling soil, and therefore the stability of the formed steep slope embankment is guaranteed. Disturbance to steep slope foundation soil is small, the constructionsafety is high, the masonry amount is small, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of roadbed engineering, in particular to a method for constructing steep-slope high embankment structures. Background technique [0002] In recent years, my country's infrastructure construction such as railways and highways has developed rapidly, and construction projects in areas with complex terrain and steep terrain play a vital role in promoting my country's modernization process. In mountainous areas with many mountains and rugged ravines, it is often necessary to set up embankments on steep slope foundations. In the existing engineering construction, the common treatment measures for steep slope embankments and their related mechanisms mainly include: 1) For steep slope embankments with reinforced soil retaining walls, the tension balance provided mainly by the tension bars anchored in the stable soil behind the wall The earth pressure exerted by the filling soil on the retaining plate. When it is n...

Problems solved by technology

2) Damage to the embankment support structure, specifically: overturning and sliding caused by poor wall stability, wall cracking caused by excessive external load and insufficient structural material strength, etc.

Therefore, it has certain practical significance to improve and innovate the existing steep slope embankment structure to solve problems such as poor soil stability, complicated construction technology, large amount of masonry, and high cost of materials.
