Municipal roadbed construction method
The invention provides a municipal roadbed construction method which comprises the steps that a construction site is cleaned, the surface layer of a foundation is loose soil, and if the thickness of the loose soil is lower than than or equal to 30 cm, the loose soil is ground to the compactness of 90% after sundries are removed; if the thickness of the loose soil is larger than 30 cm, the loose soil is compacted in a layered mode till the compaction degree is 90%; the cleaned construction site is subjected to soil material backfilling, and the accumulated thickness of the laid soil material ranges from 50 cm to 60 cm; the moisture content in the soil material is controlled to be 30-50%, a curing agent is added into the soil material, uniformly stirring and mixing are implemented, the uniformly mixed soil material is paved through a bulldozer, and the soil material is flattened; and the flattened soil material is rolled through a light path road roller so as to quickly cure the soil material added with the curing agent, and the laid multiple layers of soil materials are repeatedly rolled . The roadbed is thus paved. Due to use of the curing agent, the compaction degree and the bearing capacity of the roadbed can be improved to a certain extent.
本公开提供了一种市政路基施工方法，包括对施工场地进行清理，地基表层为松散土，若该松散土的厚度小于等于30cm，并将松散土在清除杂物后碾压至90％压实度；若松散土的厚度大于30cm，则将该松散土分层压实至90％压实度；对清理完成后的施工场地进行土料回填，且铺设的土料厚度累计厚度介于50～60cm之间；控制土料中的水分含量介于30～50％之间，并在该土料中添加固化剂进行搅拌混匀，通过推土机将混匀的土料进行摊铺，并对该土料进行平整操作；通过光路压路机对平整处理后的土料进行碾压操作，以使得添加有固化剂的土料快速固化，并重复对铺设的多层土料进行碾压。以完成路基的铺设。本公开由于固化剂的设置，能够在一定程度上提高路基的压实度及承载能力。
