Riprap silt squeezing and dynamic compaction combined construction method for soft soil stratum roadbed
The invention relates to the technical field of road roadbeds, in particular to a riprap silt squeezing and dynamic compaction combined construction method for a soft soil stratum roadbed. The method comprises the steps that S1, drainage and desilting are conducted on an original site where a needed effective tamping face is located, and then a pressure reduction ditch is dug in the edge of the needed effective tamping face; s2, rubbles are thrown and filled into the desilted original site, and layered rolling is carried out to preliminarily level a required effective tamping surface; s3, plain soil is backfilled after rolling, and double-layer dynamic compaction is conducted after leveling is conducted again; and S4, after double-layer dynamic compaction is completed, plain soil is backfilled, and the plain soil is rolled and leveled through a rolling machine till the surface reaches the designed elevation. According to the method, silt is extruded through riprapping, double-layer dynamic compaction is carried out, settlement of rubbles and formation of a roadbed can be accelerated, the problem of bearing of a soft soil stratum foundation is effectively solved, and the method is particularly suitable for engineering of deep and thick silt geology and suitable for popularization.
本发明涉及道路路基技术领域，尤其涉及一种用于软土地层路基的抛石挤淤强夯组合施工方法。该方法包括S1.对所需的有效夯实面所在原场地进行排水、清淤，然后在所需的有效夯实面的边缘开挖减压沟；S2.向清淤后的原场地内抛填片石，并进行分层碾压以初步平整所需的有效夯实面；S3.碾压后回填素土，再次整平后进行双层强夯；S4.双层强夯完成后，回填素土，并用碾压机碾压整平，直至表面达到设计标高。本方法通过抛石挤出淤泥，并进行双层强夯，可以加快片石的沉降与路基形成，有效解决了软土地层地基承载问题，特别适宜深厚淤泥质地质的工程，适宜推广。
