Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] A method for forming batches of square beams with bio-fixed soil, the method comprising the steps of:

[0042] 1) Prepare the materials needed for the mold (such as figure 1 , 2Shown): Drill holes on the plexiglass flat plate or buy ready-made plexiglass with holes, the holes on the plexiglass are arranged in dislocation (the drilling positioning is, the diameter of the hole is 6mm, the net distance between the holes is 3mm, and the holes in adjacent columns are dislocated In addition, the hole diameter and the net distance between the holes can also be modified and adjusted according to actual needs); then the plexiglass is cut into plates with a woodworking saw blade, and the plates include two longitudinal side panels 1 (241.3mm×38.1mm ), one bottom plate 2 (299.7mm×238.8mm), two end plates 3 (213.4mm×38.1mm), two longitud...

Abstract

The invention discloses a method for batched formation of square beams for biological soil reinforcement. The method for batched formation of the square beams for biological soil reinforcement comprises the following steps that (1) materials required by a mold are prepared; (2) cut organic glass plates provided with holes are assembled; (3) a light mold required for tailoring of geotechnical cloth is manufactured, and the geotechnical cloth is tailored according to the sizes of light materials; (4) the geotechnical cloth is placed in square beam mold cavity units, and sandy soil is added into cavities defined by the geotechnical cloth; (5) prepared bacteria are poured into test piece molds; (6) the two or four wetted test piece molds are placed in a container side by side, and a plurality of layers of mold sets are arranged according to the actual condition; (7) the multiple layers of mold sets are soaked in a chemical solution; and (8) the square beams for biological soil reinforcement are formed after a reaction. According to the method for batched formation of the square beams for biological soil reinforcement, by means of the flatness of the surface of organic glass and the good water permeability of the holes, cuboid test pieces formed after the chemical reaction are angular, high in surface flatness, uniform in texture and stable in mechanical property, and a scientific research test for testing the bending performance can be conducted in the later stage conveniently.

Description

technical field [0001] The invention relates to a square beam forming method, in particular to a square beam batch forming method for bio-fixed soil. Background technique [0002] my country is in a period of rapid economic development, and the demand for construction land is constantly expanding, requiring more infrastructure construction to meet people's production and living needs. However, today's construction land resources are very limited, which requires land or The sand is solidified and improved. Traditional soil improvement methods often need to add a series of polluting chemical components, which may cause water pollution problems and even affect human health. [0003] The scientific research team of the project team is studying new environment-friendly soil and sand reinforcement technology, using one of the biomineralization processes that exist widely in nature, the microbial-induced calcium carbonate precipitation method, that is, according to the urea hydroly...
