Abstract

The invention discloses a construction method of an assembled double-pipe seepage and drainage blind ditch and a subgrade seepage and drainage structure. The prefabricated double-pipe seepage drainage blind ditch includes a drainage unit connected end to end, and the drainage unit includes: a first drainage pipe, a first water seepage hole is provided on the pipe wall of the first drainage pipe; a first filter layer, the The first filter layer is wrapped on the outside of the first drainage pipe; the second drainage pipe is arranged inside the first drainage pipe, and the pipe wall of the second drainage pipe is provided with the second seepage hole; the second filter layer, the second filter layer wraps the outside of the second drain pipe and forms a cavity between the inner wall of the first drain pipe and the second filter layer. The invention has a simple structure, can be assembled in advance in the factory and then transported to the site, realizing the concept of assembly of all components, faster assembly speed and higher efficiency, less labor required for assembly, shorter assembly construction period, and lower construction cost and quality is easier to control.

Description

Technical field[0001]The present invention relates to the technical field of road seepage water, and in particular, it relates to a construction method of assembling dual-tubular oozing water blind groove and a path base seepage water structure.Background technique[0002]The road is in a belt form, often requires across a variety of complex hydrogeological environments, or even a variety of climate environments, and the performance of road street roads will be affected by factors such as soil physical mechanical properties, terrain landforms, formation conditions, water and temperature. . In order to ensure the long-term stability of the road, in the roadbed road design, it is generally designed to design corresponding response engineering measures, in which the roadbed stream filled strength reduction and the filling layer softening deformation in order to solve the development of groundwater development and the filling layer softening caused. Some problems such as cracking of road ...
