Embodiment 1

[0030] Take the following components according to mass percentage: cement base material 33.8%, fine aggregate 45%, fly ash 3.75%, expansion agent 3.75%, water reducing agent 0.53%, and the balance is configured water; the mass percentage of the above components The sum is 100%; the fineness modulus of the fine aggregate is 2.5; the expansion agent is the UEA-SM type special high-efficiency concrete expansion agent; the water reducing agent is a polycarboxylic acid superplasticizer, and the solid content of the water reducing agent is 20%; configuration water is ordinary fresh water or brine.

[0031] After uniformly mixing the above components, an anti-erosion slurry is obtained. Using the device of the present invention, the anti-erosion slurry is injected between the concrete foundation and the surrounding stratum through the grouting pump 1 through the grouting pipe 2 and the anti-erosion slurry injection device. In addition, the anti-corrosion slurry is fully mixed with the b...

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 the construction of an anti-corrosion protective layer of a concrete foundation in a saline soil area. 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. However, my country's saline soil has a wide range of distribution, showing a concentrated distribution pattern, mainly in the coastal and northwestern inland areas. Reinforced concrete structure is the main material of various buildings and structures at present. The underground brine environment (especially Cl- or SO 4 2- ) Will cause very serious erosion damage to the reinforced concrete foundation, seriously affect the safety and practical life of the concrete foundati...
