High fill quality control construction method for side slope embankment

Abstract

The invention discloses a high fill quality control construction method for side slope embankment. The high fill quality control construction method comprises the steps that dredging and foundation treatment is performed on a newly added filling surface, and at the same time, dredging treatment is performed within a certain range outside a slope foot; the slope surface of an original filled body is subjected to bench excavation according to the principle of 1 to 2, and the newly added filling body is subjected to bench excavation when an original mountain body is steeper than 1 to 5; the newlyadded filling surface is subjected to tamping filling layered construction by adopting a tamping machine or a stamping mill, packing is siltstone stone or conglomerate stone, and if the newly added filling surface is narrow and small, filling construction is carried out by vibration rolling first until the newly added filling surface meets the construction conditions of the tamping machine or thestamping mill; and when a newly added filling body is originally provided with a drainage blind ditch, the drainage blind ditch is appropriately extended to a new slope surface according to the original direction and with the level not less than the original specification to ensure smooth drainage of the blind ditch. The high fill quality control construction method overcomes the defects of uneven settlement of foundations and deformation of side slopes.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and in particular relates to a construction method for controlling the quality of middle and high filling of slopes. Background technique [0002] With the balanced development of economy, more and more new airports are built in mountainous cities. In the construction of airports in mountainous areas, it is an important part of the project to complete the earthwork construction in the widened area at the foot of the slope and to control the quality of high fill. At present, there are technical problems in the quality control of high fill in the slope and the uneven settlement of the foundation and the deformation of the slope. . Contents of the invention [0003] The purpose of this invention is to provide a kind of side slope sticking to the middle and high fill quality control construction method of the slope, which method has overcome the uneven subsidence of the foundation ...
