Construction method for highway subgrade treatment

Abstract

The invention discloses a construction method for highway subgrade treatment. The construction method comprises the following steps: 1, performing survey setting-out; 2, performing substrate treatment; 3, performing a drainage groove; 4, performing pipe pile construction; 5, performing layered filling and compacting; 6, performing surface layer construction treatment, wherein the base treatment inthe second step comprises the following steps: firstly, cleaning the roadbed ground obtained after survey setting-out, so that organic impurities and floating soil are cleaned; secondly, leveling andexcavating the cleaned roadbed ground. According to the construction method for highway subgrade treatment, quality detection is conducted while construction is conducted, and the quality of the constructed highway subgrade can be guaranteed; meanwhile, through repeated compaction, the compactness of the subgrade is guaranteed, local settlement is avoided, the strength stability of the whole structure is guaranteed, long-term stable use of a highway can be guaranteed, and the late maintenance workload is reduced.

Description

technical field [0001] The invention relates to the technical field of highway subgrade treatment construction, in particular to a construction method for highway subgrade treatment. Background technique [0002] With the continuous development of traffic, the use of roads is becoming wider and wider, and with the increase of road coverage, it is more convenient for people to travel, and in the process of road construction, the quality of the roadbed directly affects the service life of the road; [0003] Road subgrade construction includes different aspects, and requires non-compacted filling of different materials. At present, the commonly used road subgrade treatment construction methods cannot guarantee the strength of the subgrade during subgrade construction, which is not conducive to ensuring the long-term stability of the subgrade. , and the current subgrade construction and after it is put into use, it is easy to cause partial settlement to make the road surface un...

Problems solved by technology

[0004] The purpose of the present invention is to provide a construction method for roadbed treatment, to solve the current roadbed treatment construction method proposed by the above-mentioned background technology, when carrying out roadbed construction, the strength of the roadbed cannot be guaranteed, which is not conducive to ensuring the quality of the roadbed. Long-term use stability, and the current roadbed is prone to partial settlement during construction and after it is put into use, making the road surface uneven, which is not conducive to ensuring the long-term use of the roadbed
