Because "Cement Mixing Pile" has gradually been widely used in soft soil foundation treatment, foundation pit support and water-stop curtains at home and abroad (applied in various constructions, highways, traffic interchanges and other projects in Southeast Asia). Therefore, in recent years, according to the needs of the engineering market, our company has introduced professional technical personnel and equipment, and actively carried out the research and practice of "Cement-soil Mixing Pile Construction Technology", and achieved good social benefits and technical reserves. In order to improve the construction quality of the "Cement-soil Mixing Pile" and to overcome the problems of one or that restriction and impact on the quality of construction under the existing equipment conditions, the company organizes technical personnel to absorb and digest the "Cement-soil Mixing Pile" construction through various channels New processes and new technologies, in-depth research and discussion of the use of composite construction methods, and actively improve construction equipment, improve construction technology, strengthen the skill training of operators, and strive to improve project quality.
