Abstract

The invention provides a construction method and device for a soft foundation reinforced by a filmed geotextile. The method includes the steps that firstly, a bedding layer is arranged; based on the bedding layer, the filmed geotextile is laid; based on the laid filmed geotextile, a protecting layer is laid; and permeable soil is laid on the protecting layer. The method is applicable to reinforcing treatment of soft foundations of newly built railways and highways and can also be used for reinforcement and remediation of defected foundations of existing lines. In addition, in the implementation process of the method, the method has the beneficial effect of simple machines and tools, that is, on the premises of machines and tools and original sufficient conditions, section construction can be carried out without the limit of sites, the technological process is clear, and the beneficial effects of programmed and standardized operation, easy control over quality, simple and rapid quality detection and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method and a device for reinforcing a soft foundation with a membrane geotextile. Background technique [0002] In the traditional technology, the construction of railway embankment often encounters soft subgrade beds. If it is not handled properly, it will cause diseases to the railway operation and endanger the safety of traffic. Contents of the invention [0003] In view of this, it is necessary to provide a construction method and device for reinforcing soft foundations with membrane geotextiles, which are suitable for the reinforcement treatment of new railways and road soft foundations, and can also be used for reinforcement and improvement of existing line disease roadbeds. [0004] In order to achieve the purpose of the invention, a construction method for reinforcing a soft foundation with a filmed geotextile is provided, a bedding layer is...
