Construction technology for filling subgrade with silty soil

Abstract

The invention discloses a construction technology for filling a subgrade with silty soil, belongs to the field of subgrade construction, and solves the problem of high construction cost of supplementing water content of the silty soil filler by using a prior construction method relying on a sprinkler. The technology comprises paving fillers on the subgrade layer by layer, each filler is filled separately, the filling comprises the following steps of: 1: preparing the filler, determining the single-layer filler demand according to the construction area and compaction thickness of the filler, and making a ratio; 2: detecting the moisture content of the filler; wherein the moisture content in the filler is detected; 3: discharging the filler and flatting by pushing, wherein the filler is paveon the subgrade in a flat mode; 4: adjusting the moisture content in the filler; wherein when the moisture content of the filler is higher than a calibration value, the filler is turned into the sun;when the moisture content in the filler is lower than the calibration value, the water content of the filler is replenished by laying several sprinkler irrigation belts; 5: rolling the filler, rolling the filler by using a rolling machine; the construction method of sprinkling irrigation belt is adopted for supplementing the water in the filler to reduce the construction cost.

Description

technical field [0001] The invention belongs to the field of roadbed construction, and specifically relates to a construction technology for filling a roadbed with silt soil. Background technique [0002] At present, due to the consideration of economical reasons, most of the roadbed filling materials are locally sourced. According to the different areas where the project is located, the roadbed fillings generally include block stones, soil-rock mixed fillers, silty soil, cohesive soil and sandy soil, etc., silt soil Between silty soil and sandy soil, there are problems such as small particles, poor water retention, and difficult compaction. The above problems can be overcome by adding water content to the filler, but the traditional construction method relying on sprinklers has high construction costs. . Contents of the invention [0003] The purpose of the present invention is to provide a kind of silt soil filling roadbed construction technology that overcomes the shor...

[0002] At present, due to the consideration of economical reasons, most of the roadbed filling materials are locally sourced. According to the different areas of the project, the roadbed fillings generally include block stones, earth-rock mixed fillers, silty soil, cohesive soil and sandy soil, etc., silt soil Between silty soil and sandy soil, there are problems such as small particles, poor water retention, and difficult compaction. The above problems can be overcome by adding water content to the filler, but the traditional construction method relying on sprinklers has high construction costs.
