Embodiment 1

[0034] see figure 1 and figure 2 , the deep stirring pile equipment shown in the illustration is a preferred embodiment of the present invention, and specifically includes three parts: a drill pipe assembly, a drug delivery assembly and a grouting assembly.

[0035] Wherein the drill pipe assembly includes a drill pipe 1, a drill pipe linkage motor 2, a drill pipe lifting column 3, and a drill pipe support 4. The drill pipe 1 adopts a hollow drill pipe, and the head end of the drill pipe is provided with an auger for drilling and mixing soil. The tail end of the rod is connected with the drill pipe linkage motor 2, and is installed together on the drill pipe lifting column 3. The drill pipe lifting column 3 is vertically arranged on the drill pipe support 4, and a winch mechanism for lifting the drill pipe is provided on it. The hoisting mechanism is relaxed, and the drill pipe is cut and mixed with the soil from top to bottom under the action of the drill pipe linkage motor...

Abstract

The invention discloses deep-layer stirring pile equipment for soil restoration and a construction method thereof. The deep-layer stirring pile equipment comprises a drill rod assembly, a farm chemical feeding assembly and a cement paste adding assembly; the drill rod assembly comprises a drill rod, a drill rod linkage motor, a drill rod lifting stand column and a drill rod bracket, the drill rod and the drill rod linkage motor are installed on the drill rod lifting stand column at the same time and driven by a hoisting mechanism on the drill rod lifting stand column to ascend and descend, and the drill rod lifting stand column is arranged on an equipment foundation support through the drill rod bracket; the drill rod is hollow, an inner cavity of the drill rod is connected with a farm chemical conveying pipe of the farm chemical feeding assembly and a cement paste conveying pipe of the cement paste adding assembly in parallel, and cement paste and restoration agentia are added into drilled soil in sequence. The deep-layer stirring pile equipment capable of conducting precise positioning is utilized to drill and cut contaminated soil on the spot; and meanwhile, the cement paste and restoration agentia are sequentially injected into the contaminated soil from the front end of the drill rod so that the cement paste and restoration agentia can be mixed and stirred with the contaminated soil repeatedly in the stirring process to form cement paste agentia to restore the soil, and finally the effect of in-situ restoration of the contaminated soil is achieved.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a deep mixing pile equipment and a construction method for soil restoration. Background technique [0002] As my country pays more and more attention to environmental protection, soil remediation is also included in the "13th Five-Year Plan". The commonly used technical measure for soil remediation is the method of solidification / stabilization treatment. The method refers to the use of physical or chemical methods to fix harmful pollutants in the soil, or to convert pollutants into chemically inactive forms, preventing It is a remediation technology that reduces the toxicity of pollutants through the process of migration and diffusion in the environment. [0003] General soil solidification / stabilization treatment needs to excavate the polluted soil first, and transport it to the solidification / stabilization workshop for treatment. Not only the cost is high,...
