Abstract

The invention discloses construction complete equipment for an erosion-resistant protective layer of a concrete foundation in a salty soil zone. The construction complete equipment comprises a grouting pump and an erosion-resistant slurry injection device; the grouting pump and the erosion-resistant slurry injection device are connected through a grouting tube; the erosion-resistant slurry injection device is used for grouting erosion-resistant slurry into a position between the concrete foundation and a surrounding stratum; the erosion-resistant slurry injection device comprises a grouting main pipeline which is connected to the grouting tube; and a plurality of joints are further connected on the grouting main pipeline, and are connected to grouting branch pipelines. The construction complete equipment disclosed by the invention can grout an erosion-resistant material between the periphery of underground construct concrete and a surrounding bottom layer; and the erosion-resistant protective layer is formed at a concrete outer layer. The construction complete equipment solves the problems of high engineering construction cost, not strong adaptability and a complex construction process of an existing erosion-resistant protective technology.

Description

technical field [0001] The invention belongs to the technical field of concrete foundation construction, and relates to a complete set of equipment for constructing an anti-corrosion protective layer of concrete foundations in saline soil areas. Background technique [0002] With the rapid development of my country's economy, the development and utilization of my country's underground space has entered a stage of rapid development, requiring the construction of a large number of underground structures. In my country, saline soil is widely distributed in a concentrated distribution form, mainly in the coastal and northwest inland areas. Concrete steel structure is the main material of various buildings and structures at present, and the underground brine environment in saline soil areas (especially Cl- or SO 4 2- ) will cause very serious erosion damage to the reinforced concrete foundation, seriously affecting the safety and practical life of the concrete foundation, and c...
