Problems solved by technology
Taking tidal flat areas such as the Bohai Sea and the Yellow Sea as examples, the geological surface layer is a typical soft foundation area of saturated cohesive soil. It is undoubtedly difficult to build permanent and temporary roads on this soft soil. If the corresponding road design level is greatly improved, because the soft foundation treatment For other reasons, the investment of the entire road will be greatly increased; at the same time, if the corresponding road design level is lowered, considering the high sea level on one side of the road, the high requirements for the road carrying capacity of the road traffic vehicles, and the short construction period and other unfavorable factors, often Part of the road that has been built is washed away by the high tide that often occurs, the soil on the side of the road is "hollowed out" by the tide, and the road surface structure is repeatedly rolled by road vehicles to form "spring soil". At this time, additional investment is required. Reinforce the road twice, so the economy and applicability are very poor

The invention provides a seaside soft foundation road structure which comprises a road body structure and a road protection structure. The road body structure comprises a clay roadbed, a quick lime bottom layer laid at the upper end of the clay roadbed, a cement soil stable isolation layer laid above the quick lime bottom layer, a limestone soil base layer laid above the cement soil stable isolation layer and a cement curing face layer laid above the limestone soil base layer. The road protection structure comprises a composite geo-membrane layer arranged on the surface of the slope of the clay roadbed, a paste locating flatly-built brick layer arranged on the surface of the composite geo-membrane layer and reinforced concrete suppressing pins arranged at the bottom of the slope of the clay roadbed. The upper end of the composite geo-membrane layer is pressed to the position below the quick lime bottom layer, and the lower end of the composite geo-membrane layer is pressed to the position below the reinforced concrete suppressing pins. The seaside soft foundation road structure is high in strength and good in durability and economical efficiency.
Description
technical field [0001] The invention relates to the technical field of road structures, in particular to a seaside soft ground road structure. Background technique [0002] With the development of the economy, due to the limited land resources, human beings are moving more and more towards the tidal flat area, and corresponding engineering projects will follow. At this time, corresponding permanent or temporary roads must be built. Taking tidal flat areas such as the Bohai Sea and the Yellow Sea as examples, the geological surface layer is a typical soft foundation area of saturated cohesive soil. It is undoubtedly difficult to build permanent and temporary roads on this soft soil. If the corresponding road design level is greatly improved, because the soft foundation treatment For other reasons, the investment of the entire road will be greatly increased; at the same time, if the corresponding road design level is lowered, considering the high sea level on one side of the...
