Method for building shortcut on peat soil soft foundation

Abstract

The invention provides a method for building a shortcut on a peat soil soft foundation, and belongs to the technical field of engineering construction. The method comprises the steps that firstly, the original ground is cleared and leveled into a pavement; secondly, geotechnical cloth is paved on the pavement, and a length is reserved on the geotechnical cloth to be used for fixing the geotechnical cloth; thirdly, sand bags are paved on the geotechnical cloth, and every two adjacent sand bags are fixedly connected; fourthly, wood piles are driven on the two sides of the pavement and are used for fixing the sand bags; and fifthly, after standing is carried out for a preset time, hill-skill soil of a preset thickness is paved on the sand bags, and the hill-skill soil is compacted to complete building of the shortcut. The method is applied to building the shortcut on the peat soil soft foundation, overall stability of the shortcut is reinforced, the shortcut is resistant to water erosion, the cost of the adopted sand bags and other raw materials is low, materials are taken conveniently, and the method is high in safety and beneficial to ecological environmental protection.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a method for building an access road on peat soil soft foundation. Background technique [0002] In the construction process of highway bridge and culvert projects, the construction of access roads is the primary task in the construction stage, and the quality of access roads determines the overall cost and construction efficiency of the project. In the prior art, the sidewalk is filled with sand or stones, but in the soft peat soil foundation area, due to its low bearing capacity, high compressibility, high water content and high porosity, it is difficult to fill it in practice. During the construction and construction process, the sidewalk above the peat soil soft foundation often undergoes local or even overall landslides or overall piercing subsidence during the rainy season, which not only seriously affects the construction efficiency, but also increases mai...

Problems solved by technology

[0003] In view of this, the purpose of the present invention is to provide a method for building access roads on peat soil soft foundations, so as to solve the problems in the prior art that it is difficult to build access roads on peat soil and other soft foundation roads, the cost is large, and the access roads after construction are resistant to rainwater. Poor ability, difficulty in later demolition, etc.
