石灰改良黄土路基薄层静压路拌施工技术

Construction Technology of Lime-improved Thin-layer Static Pressure Road Mix for Loess Roadbed

黄土具有湿陷性,用其修筑的路基常出现承载能力不足现象,一般工程常通过掺杂石灰改良土质。目前路拌施工中常采用的拌合设备为装载机和旋耕机配合,碾压方法常用振动碾压法。该设备搭配具有石灰拌合均匀性存在不良的风险大,且震动碾压会对周围建筑物的结构造成一定的伤害。本文将介绍石灰改良黄土路基薄层静压路拌的施工技术。

Due to the collapsibility of loess,roadbeds built with it often have insufficient bearing capacity.Common engineering often improves soil quality by doping with lime.At present,the mixing equipment often used in road mixing construction is the combination of a loader and a rotary tiller,and the rolling method is usually a vibration rolling method.This equipment has a high risk of poor lime mixing uniformity,and the vibration and rolling will cause certain structure damage to the surrounding buildings.This article will introduce the construction technology of lime-improved thin-layer static pressure road mix for loess subgrade.
