Improvement of intelligent rock avoiding device and its application method by over-humidity and bad filler in embankment

Abstract

The invention discloses an improved intelligent stone avoidance device for road embankment over-wet and poor filling and a method for using the same. The shaft is connected by transmission, the inner cavity of the auger bit is connected with the outlet of the heating tube bundle, the drill body of the auger bit is evenly provided with a plurality of small holes, the material conveying pipe for transporting the improved water absorbing agent is connected with the heating tube bundle; the driving unit slides with the inner wall of the box Connection, the telescopic head of the hoist is connected to the top of the box, the end face of the drive unit away from the auger head is installed with a spring, the force-bearing surface of the spring is installed with a pressure sensor, and the pressure sensor is electrically connected to the hoist through the controller. The invention integrates the functions of soil turning, drying, filling improvement and automatic stone avoidance, and has the advantages of reasonable structure, convenient operation and low cost, which can quickly reduce the moisture content of the over-wet soil, and simultaneously improves the embankment filling and intelligently avoids the stone.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering and the technical field of embankment engineering, and relates to an improved intelligent stone-avoiding device for embankment with over-humidity and bad filling and a method for using the same. Background technique [0002] The compaction and filling of embankments with wet and bad fillers is one of the hot issues in geotechnical engineering research. In recent years, in coastal rainy areas, the frequency of rainfall is high and the amount of precipitation is high. Embankment fillings are often in an over-humid state, resulting in low embankment bearing capacity, poor stability, and easy deformation. The "spring" phenomenon is prone to appear during construction and it is difficult to compact: " Highway Embankment Construction Technical Specifications (JTJ033-95) requires embankment construction in special areas, and soil with a liquid limit greater than 50 and a plasticity index greater t...

Problems solved by technology

[0005] 2. For the embankment plowing process, it is an indispensable process of embankment construction. At present, there are a series of machines for embankment plowing, but they all face a problem. During the plowing process, it is easy to encounter some hard large stones, often These "hard bones" will cause damage to the scarification machine, especially the drill bit or tooth cutter used for scarification, so the scarification efficiency is not high and it will cost a lot of maintenance costs. Therefore, in order to make the fill scarification process more efficient and How to design a device that can effectively avoid rocks is the second problem worth studying
