Embodiment 1

[0021] A method of controlling compaction for soft ground treatment and replacement of natural sand and gravel provided by the present invention, measuring and setting out and drawing cross-sectional diagrams according to the depth and range of excavation for construction and setting out, spreading out excavation lime lines, and drawing excavation cross-sectional diagrams ; Before excavation, it is necessary to fully prepare for various preparations, repair access roads, ensure continuous operation of excavators, and equip sufficient dump trucks. Once excavated, continuous construction should be carried out to prevent the base from being soaked by rainwater; After designing the required section, if there are still non-applicable materials, the excavation shall be continued according to the required width and depth, and replacement shall be carried out. During foundation replacement construction, if the excavation line on the outer side of the slope toe exceeds the range of road...

Abstract

The invention discloses a controlled compacting method for soft foundation treatment by replacing and filling natural grit. The method comprises the steps such as construction preparation, road trough excavation, determination of a loose paving coefficient of a layering thickness gauge, substrate rolling, paving and leveling, rolling and the like. The controlled compacting method disclosed by the invention is an effective controlled compacting method for soft foundation treatment by replacing and filling natural grit, wherein clearing is needed after substrate excavation, and water content of substrate soil is controlled. In a paving process, the loose paving coefficient of paving needs to be ensured. In a rolling process, the rolling is carried out from the two sides to the center, a transverse joint is superposed by 0.4-0.5m, and two adjacent zones are longitudinally superposed by 2.0m, so that the surface is free of obvious wheel marks, and negated rolling and a dead angle are avoided; and in order to guarantee compactness degree, rolling speed of rolling machinery does not exceed 3-4km / h.

Description

technical field [0001] The invention relates to a controlled compaction method for soft foundation treatment and replacement of natural gravel. Background technique [0002] The traditional soft ground treatment method cannot fully compact it. The invention can avoid obvious wheel tracks, pressure leakage and dead angles on the surface of the soft foundation, and ensure that the compaction degree does not exceed 3-4km / h for the rolling speed of the rolling machine. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0004] The present invention relates to a method for controlling compaction of natural sand and gravel for soft foundation treatment, measuring and setting out and drawing cross-sectional diagrams, carrying out construction and setting out according to the excavated depth and range, spreading out excavation lime lines, and drawing excavation c...
