Improvement device and improvement method for collapsible loess roadbed
The invention discloses an improvement device and an improvement method for a collapsible loess roadbed, and relates to the technical field of building construction equipment. The device comprises a machine table, handles are arranged on the two side faces of the machine table, and a first liquid storage tank and a second liquid storage tank are fixedly connected to the bottom face of the machinetable; one surface of each of the first liquid storage tank and the second liquid storage tank is fixedly connected with a micro high-pressure pump; one ends of water inlets of the two miniature high-pressure pumps are respectively communicated with the first liquid storage tank and the second liquid storage tank; and the top face of the machine table is fixedly connected with a mounting frame. The collapsible loess subgrade is reinforced by adopting a chemical reinforcement principle, a chemical reagent is injected into foundation soil by the two liquid outlets in a high-pressure and high-speed rotating state during working, a gelling substance is generated or the surfaces of soil particles are activated through a chemical reaction, and the soil particles are combined, so that the soil body strength of the collapsible loess subgrade is effectively improved.
本发明公开了一种湿陷性黄土路基的改良装置及改良方法，涉及建筑施工设备技术领域。本发明包括机台，机台两侧面均设置有把手，机台底面分别固定连接有第一储液箱和第二储液箱；第一储液箱和第二储液箱一表面均固定连接有微型高压泵；两微型高压泵进水口的一端分别与第一储液箱和第二储液箱连通；机台顶面固定连接有安装架。本发明采用化学加固原理以对湿陷性黄土路基进行加固，工作时两个出液孔以高压高速旋转状态将化学试剂注入地基土中，通过化学反应生成胶凝物质或使土颗粒表面活化，并使土颗粒相结合，继而有效提高湿陷性黄土路基的土体强度。
