Environmentally friendly feeding device for intelligent cement-soil mixing pile

Abstract

The invention discloses an environment-friendly type charging and feeding device for an intelligent cemented soil mixing pile. The environment-friendly type charging and feeding device comprises a material collecting tank, a material conveying tank, an ash conveying header tube, an intelligent control system and a high-pressure gas supply system, wherein the material collecting tank and the material conveying tank are connected through a flexible connecting sleeve; the material conveying tank is provided with a weight measuring sensor for measuring weight of the material conveying tank; during drilling, quantitative cement ash is conveyed to a hole bottom by virtue of high-pressure air; during drill rod lifting, the high-pressure gas in the material conveying tank is input to a drill bit through the ash conveying header tube; high-pressure air can be injected to compensate when gas pressure in the material conveying tank is insufficient; waste gas which is exhausted into air is utilized to achieve environment-friendly effect; and meanwhile, by virtue of the action of the high-pressure air, a cement material and a soil body are mixed more uniformly, and resistance during lifting of a drill rod is reduced, so that energy-saving effect is achieved. By intelligently controlling ash charging and gas charging, the environment-friendly type charging and feeding device is simple in structural formula and convenient in mounting; dust-free construction can be realized, influence on a surrounding environment is avoided, civilized construction is realized and the cement material is saved; and cheating on workmanship and materials is avoided, so that the construction quality is completely guaranteed.

Description

technical field [0001] The invention relates to a soft soil foundation treatment technology, in particular to an environment-friendly feeding and feeding device for an intelligent cement-soil mixing pile. Background technique [0002] Soft soil foundations are often distributed along my country's coasts and river basins. Under the dynamic effects of loads, cycles, and vehicles, foundation settlement is the main form of foundation failure, which often leads to quality problems in highways, railways, airports, and docks. Among the various methods of dealing with soft soil foundation, the most widely used method is to choose composite foundation. The one-way and two-way cement-soil mixing pile forms selected in the soft soil treatment will greatly improve the strength of the composite foundation. However, the structure of the existing mixing pile machine feeding and feeding device is complex, requiring two operators, and the labor cost is high; the environmental pollution is s...

Problems solved by technology

However, the structure of the existing mixing pile machine feeding and feeding device is complex, requiring two operators, and the labor cost is high; the environmental pollution is serious during construction, because the cement dust is scattered everywhere, which seriously affects the growth of surrounding crops, often causing work obstruction. Phenomenon, even collective petitions, affecting social stability; construction quality due to human factors lead to serious phenomenon of cutting corners, construction quality cannot be guaranteed
