A particle-inspired microbial soil-fixing and wall-retaining device

Abstract

The invention discloses a particle excitation type microorganism soil fixation protection wall device. The device comprises a grouting cylinder and a central shaft; four partition plates divide the interior of the grouting cylinder into two liquid storage chambers and two particle storage chambers, four columns of base pipes are arranged on the outer wall of the grouting cylinder, wherein the twocolumn of base pipes communicate with the liquid storage chambers respectively, the remaining two columns of base pipes communicate with the particle storage chambers, a plurality of baffles are arranged on the inner wall of each particle storage chamber, a side plate is arranged on the end part of each baffle, the horizontal lengths of a plurality of solidified particle grooves are sequentially increased from top to bottom, and a stretchable pipe is arranged inside each base pipe. According to the device, the naturally occurring bacillus pasteurii in the soil layer can be excited in situ, thebacillus pasteurii can be advantageously grown by utilizing a specific culture solution, so that the environmental pollution problem caused by the introduction of microorganisms from the outside is effectively avoided, meanwhile, the soil fixation range of the microorganisms can be effectively improved, and the problem that the cured product at the early stage of a grouting port impedes the migration and diffusion of subsequent solutions is solved fundamentally.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction in land reclamation areas, in particular to a particle-inspired microbial soil fixation and wall protection device. Background technique [0002] With the rapid development of the national economy, infrastructure construction has advanced by leaps and bounds, available land resources have become increasingly scarce, and coupled with the in-depth implementation of major strategic deployments of maritime powers, large-scale island and reef construction projects have sprung up like mushrooms after rain. Since dredger fill is a special medium with a large void ratio, high compressibility, and low bearing capacity, it will inevitably encounter a series of geotechnical engineering problems when reclamation and construction of engineering facilities, especially the necking of cast-in-place piles. Engineering accidents such as hole collapse and pile deflection are the most prominent, ...
