A Construction Dredging Mud Foundation Pit Filling Material Spraying and Mixing Construction Device

Abstract

A material spraying and stirring construction device for filling a foundation pit through building dredging mud is characterized by comprising a plurality of guide rails evenly and symmetrically distributed on the wall face of the foundation pit, sliding blocks are clamped to the guide rails, a main slurry pipe is connected between every two symmetric sliding blocks, and branch spraying nozzles and stirring blades are evenly distributed on the upper faces of the main slurry pipes; transition channels are further arranged inside the sliding blocks, slurry injection pipes are connected to the inlet ends of the transition channels, and slurry discharging pipes are connected at the outlet ends of the transition channels and in the main slurry pipes; motors are installed on the side edge of the top of the foundation pit, gears are arranged at one ends of the main slurry pipes, and transmission chains are connected between the motors and the gears. Compared with the prior art, the material spraying and stirring construction device has the advantages that the dredging mud can be directly sprayed and stirred in the foundation pit to meet the requirement of filling soil for building engineering, the device is simple in structure, the treatment process of the dredging mud is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a building dredging mud foundation pit filling material spraying and mixing construction device. Background technique [0002] During the dredging of ports and waterways, a large amount of dredging silt is usually produced. Due to the large amount, the problem of dredging mud disposal is particularly prominent in the construction and maintenance of ports and waterways. The dredged mud produced in the dredging project is usually stacked or discarded, which takes up a lot of land, and the marine environment pollution caused by marine mud dumping has been increasingly restricted by various aspects. In addition, in the construction process of coastal projects such as ocean ports, a large amount of earth and stone is usually required for land reclamation. my country's coastal port cities are mostly located in alluvial plains and delta areas. It is difficult...
