Abstract

The invention discloses a guniting processing device for pavements on soft foundations. The device comprises a drill tank and an auxiliary wing, wherein the auxiliary wing is arranged below the drill tank; the device is characterized in that the drill tank is of a hollow structure, the top of the drill tank is provided with a joint, a movable chuck is arranged on the joint, the auxiliary wing is communicated with the hollow structure of the drill tank, a material spray head is arranged on the auxiliary wing, and the material spray head is provided with multiple material spray holes; a fencing cover is arranged above the drill tank, a grouting pipe is arranged on the fencing cover, a telescopic rod is arranged between the grouting pipe and the movable chuck, and the grouting pipe, the telescopic rod, the movable chuck and the joint are communicated in a penetrating mode; and a rotating column is connected with the top of the drill tank. The device is mechanically driven to enter soft soil to carry out material spray, so that a liquid curing agent and a soft soil foundation are mixed more uniformly, thereby increasing the bearing capacity of the foundation. The device disclosed by the invention is reasonable in design, high in construction speed, and suitable for being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a spray grouting treatment device for soft ground pavement. Background technique [0002] Soft soil generally refers to the fine-grained soil whose appearance is mainly gray, the natural void ratio is greater than or equal to 1.0, and the natural water content is greater than the liquid limit. Including silt, silty soil (silty cohesive soil silt), peat, peaty soil, etc. It is mainly composed of silt deposits with high natural water content, high compressibility, low bearing capacity and a small amount of humus. Soft soil refers to fine-grained soil with high natural water content, large void ratio, high compressibility, and low shear strength deposited in coastal areas, lakes, valleys, and river beaches. It has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolid...
