An intelligent cement-soil mixing pile adding and feeding operation method for pile formation

Abstract

Disclosed is an intelligent charging and feeding pile formation operation method of a cement soil mixing pile. An intelligent conveying system, a main ash conveying pipe connected with a pile machine and a high-pressure gas supply system are included; a collecting tank and a conveying tank of the intelligent conveying system are connected through a flexible connecting sleeve, and the conveying tank is provided with a weighing sensor for measuring the weight of the conveying tank; during drilling, high-pressure air conveys quantitative concrete grey to a hole bottom; and when a drill rod is lifted, the high-pressure gas in the conveying tank is input into a drill bit through the main ash conveying pipe. Waste gas exhausted to the air is utilized for achieving the environment-friendly effect, and meanwhile, due to the effect of high-pressure air, cement materials and a soil body are mixed more evenly; and resistance during lifting of the drill rod is reduced, and the energy-saving effect is achieved. Ash adding and aeration are intelligently controlled, the structural manner is simple, and mounting is convenient; dustless construction can be achieved, and no effects on the surrounding environment exist; civilized construction is carried out, and the cement materials can be saved; and jerry building is completely eradicated, and the construction quality is thoroughly ensured.

Description

technical field [0001] The invention relates to a soft soil foundation treatment technology, in particular to an intelligent cement-soil mixing pile plus feeding operation method for pile formation. 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 serious...

AI Technical Summary

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
