Improved device for collapsible loess roadbed
The invention discloses an improvement device for a collapsible loess roadbed, comprising: an outer drill rod inserted into a roadbed to be improved, the outer wall of the outer drill rod being provided with a plurality of expansion stirring assemblies; the inner drill rod is rotationally connected to an inner cavity of the outer drill rod, and the bottom end of the inner drill rod extends out of the outer drill rod and is fixedly connected with a drill bit; a mixing assembly is arranged in the inner drill rod, and a liquid outlet assembly is arranged on the side wall of an inner cavity of the inner drill rod and extends out of the outer drill rod. A first driving assembly and a second driving assembly are fixedly installed in the driving frame, the first driving assembly is in transmission connection with the outer drill rod, and the second driving assembly is in transmission connection with the inner drill rod; and a liquid supply assembly communicated with the inner cavity of the inner drill rod is mounted on the driving frame. According to the method, the collapsibility of the loess roadbed is improved, the bearing capacity of the loess roadbed is improved, the problems of slippage, collapse and the like of a road surface are prevented, the driving safety is improved, and the service life of the road is prolonged in a manner of spraying and permeating the improver at high pressure and mixing the improver with loess.
本发明公开一种湿陷性黄土路基的改良装置，包括：外钻杆，外钻杆插入待改良路基内，外钻杆的外壁设置有若干扩张搅拌组件；内钻杆，内钻杆转动连接在外钻杆内腔，内钻杆的底端伸出外钻杆并固接有钻头；内钻杆内设置有混合组件，内钻杆的内腔侧壁设置有出液组件，出液组件伸出外钻杆；驱动架，驱动架内固定安装有第一驱动组件和第二驱动组件，第一驱动组件与外钻杆传动连接，第二驱动组件与内钻杆传动连接；驱动架上安装有与内钻杆内腔连通的供液组件。本发明通过高压喷射渗透改良剂并与黄土混合的方式，改良黄土路基的湿陷性，提高黄土路基的承载力，防止路面出现滑移、塌陷等问题，提高行车的安全性，延长道路的寿命。
