Soft soil stratum in-situ curing agent preparing and feeding equipment and curing process thereof

Abstract

The invention discloses a soft soil stratum in-situ curing agent preparing and feeding equipment and curing process thereof, the soft soil stratum in-situ curing agent preparing and feeding equipment comprises an excavator and curing agent preparing equipment, a material conveying pipe is arranged between the excavator and the curing agent preparing equipment, the curing agent preparing equipment is provided with an automatic quantitative feeding system, the excavator is provided with a bucket arm, the tail end of the bucket arm is connected with a powerful stirring head, and the curing agent preparation equipment comprises a storage tank, a pressure chamber and an air compressor. The soft soil stratum in-situ curing agent preparing and feeding equipment and the curing process thereof replace a traditional replacement filling method for treating the soft soil stratum, zero discharge of engineering waste soil can be achieved, the influence degree of transportation and the waste soil on the environment is reduced, a large number of replacement materials do not need to be used, the use amount of gravel is reduced, and mountain cutting quarrying and river channel sand digging are reduced; the influence on surrounding buildings is reduced, the construction speed is increased, a hard shell layer can be quickly formed, cyclic utilization of resources is achieved, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of solidification of soft soil strata, in particular to equipment for preparing and supplying an in-situ curing agent for soft soil strata and a curing process thereof. Background technique [0002] With the development of my country's engineering construction, more and more ultra-soft soils and special soil complex foundations have been encountered, such as: sea reclamation land reclamation foundations, river ponds, fish ponds, swamp foundations, mud dumps, polluted soil, etc. , if the traditional method is used to replace and fill, a large amount of engineering waste soil will be generated, and a large amount of sand and gravel and other high-quality fillers will be required. Spoil transportation, stacking and disposal can also affect urban sanitation and traffic. In addition, in the treatment of road soft foundation, it is often encountered in some road sections without hard crust, the strength and bearin...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the solidification of soft soil strata in the prior art is mostly treated by the replacement and filling method. The displacement of engineering waste soil is large, and the transportation and abandonment have an impact on the environment. It is necessary to use a large amount of replacement materials and the amount of sand and stone increase, the need for mountain quarrying and river channel sand dredging works will have an impact on surrounding buildings, and the construction speed is slow, resulting in waste of resources, insufficient energy conservation and environmental protection, and the proposed on-site curing agent preparation and feeding equipment for soft soil stratum Its curing process
