The invention discloses a solidification structure for a calcareous sand foundation. The solidification structure comprises a pile body struck into a soil body, and is characterized in that the pile body comprises a pile body upper section and a pile body lower section, the pile body upper section corresponds to a calcareous sand layer, the pile body lower section goes deep into a soil layer underthe calcareous sand layer, the pile body upper section is provided with a bacterium solution conveying channel with an upward opening, the bacterium solution conveying channel communicates with a liquid outlet in the side wall of the pipe body upper section, a lateral water permeating hole is formed in the liquid outlet, and the upper end of the bacterium solution conveying channel is connected with a bacterium solution preparation and conveying device through a guide pipe. According to the solidification structure for the calcareous sand foundation, a deep soil body can be reinforced throughthe pile body, the calcareous sand layer can be subjected to all-around bacterium solution conveying through the pile body upper section to form biological solidification, cleanliness and environmental friendliness of the soil body can be kept while a shallow soil body is solidified, and the solidification structure can be suitable for later planting of plants.
Description
technical field [0001] The invention relates to a solidified structure of calcareous sandy soil foundation, in particular to a structure using bacterial liquid to solidify the calcareous sandy soil foundation. Background technique [0002] The reinforcement of traditional calcareous sandy soil foundation mainly adopts traditional pile foundation, and the pile body is supported in the bearing layer of the soil, but this reinforcement method cannot solve the problem that the calcareous sandy soil layer is easy to collapse and has poor supporting performance. [0003] The method of microbial reinforcement of calcareous sandy soil can be environmentally friendly and efficient reinforcement of calcareous sandy soil. The reinforcement of traditional calcareous sandy soil includes biological reinforcement methods, including the following steps: [0004] A. First, add 0.1mol organophosphate monoester solution into 1 liter of phosphate mineralizing bacteria liquid, and let stand at r...
