Problems solved by technology

[0004] Most of the existing indoor soft soil curing devices use grouting devices, which will inevitably increase the water content of the soil, because the grout originally contains water, so the reinforcement effect is not good; and the operation is inconvenient, the stirring speed is very slow, and the stirring is not uniform

Abstract

The invention discloses an indoor soft soil powder spraying solidifying device and belongs to the field of soft soil solidifying devices. The indoor soft soil powder spraying solidifying device comprises a test box and a bracket which is arranged above the test box, the bracket is provided with a stirring device, and the stirring device is connected with an input device. The input device comprises a feeding pump for spraying powder-shaped solidifying agent and an air compressor for filling high-pressure air, the feeding pump is connected with a feeding pipe, the feeding pipe is provided with a feeding valve, the air compressor is connected with an air supply pipe, and the air supply pipe is provided with an air supply valve. The stirring device comprises a stirring shaft and a motor, the stirring shaft comprises a rotating part and a stirring part, and the rotating part is connected with the motor. A solidifying agent flow passage is arranged in each of the rotating part and stirring part, the upper end of the rotating part is communicated with each of the feeding pipe and air supply pipe through a pipeline, and a stirring blade and an opening are arranged at the lower end of the stirring part. The indoor soft soil powder spraying solidifying device is simple in structure, easy to operate, more uniform in stirring and good in solidifying effect.

Description

technical field [0001] The invention relates to the field of soft soil curing devices, in particular to an indoor soft soil powder spray curing device. Background technique [0002] Solidified soil is a general term for the consolidated body formed by mixing the solidifying agent slurry with the soil by grouting, deep mixing, and high-pressure rotary spraying. It is mainly used for channel seepage prevention, bridges, culverts, and The supporting project of the gate can also be used for dam slope protection, road stability layer, cushion layer of large channels, etc., especially suitable for areas lacking sand and gravel. [0003] For the curing of soft soil, the results obtained from the indoor test are quite different from the real reinforcement effect on site. In most indoor tests, the undisturbed soil was crushed and dried, and then made into remolded soil with the same water content as the undisturbed soil. The curing agent consolidates the remolded soil. Because the ...
