Multi-liquid composite micro-disturbance cement-soil mixing pile equipment

Abstract

The invention discloses multi-liquid composite micro-disturbance cement-soil mixing pile equipment which comprises an equipment body. The equipment body comprises a power head, a water glass spraying pipe and a multi-liquid gas spraying pipe; a driving motor is connected onto the power head; the output end of the driving motor is connected with a driving rod; and the outer side of the bottom of the driving rod is connected with blades distributed at equal intervals. According to the multi-liquid composite micro-disturbance cement-soil mixing pile equipment provided by the invention, liquid can be sprayed while being stirred after construction, the spraying position and the stirring position are kept consistent at any time, cement soil can quickly reach the strength of undisturbed soil, damage caused by too long deformation time and too large deformation of adjacent subway tunnels or other important buildings is avoided, and construction parts where the strength of cement stirring soil needs to reach or exceed the strength of the undisturbed soil rapidly can be reinforced or subjected to water stopping; meanwhile, the multi-liquid composite micro-disturbance cement-soil mixing pile equipment can be universally used with traditional cement soil mixing pile equipment accessories and is convenient to mount, dismount and maintain; the multi-liquid composite micro-disturbance cement-soil mixing pile equipment is suitable for soft soil and common non-hard soil layer foundation reinforcement and SMW construction method enclosure water stop.

Description

technical field [0001] The invention relates to the technical field of mixing pile equipment, in particular to a multi-liquid composite micro-disturbance cement-soil mixing pile equipment. Background technique [0002] With the rapid development of the national economy, the construction of urban subways is advancing by leaps and bounds, and the subway lines in large and medium-sized cities are criss-crossing. While alleviating the pressure on urban traffic, it also brings a series of construction safety problems. The first is the foundation soil reinforcement construction near the subway tunnel. Liquefaction disturbed soil on the safety of subway operation. [0003] At present, during the construction of cement-soil mixing piles, the early-strength liquid cannot be sprayed into the cement-soil in time, and the mixing is not uniform enough, so that the cement-soil after construction cannot quickly reach the strength of the original soil, resulting in the adjacent subway Tunn...
