Description

Particle excitation type microorganism soil stabilization wall protection device

Technical Field

The invention relates to the technical field of construction of pile foundations in land reclamation areas, in particular to a particle excitation type microorganism soil fixation and wall protection device.

Background

With the rapid development of national economy, infrastructure construction is rapidly advanced, available land resources are increasingly poor, and large-scale island and reef building engineering is vigorous as bamboo shoots in spring after rain in addition to deep implementation of major strategic deployment of ocean forcing countries. Since the dredger fill is a special medium with large pore ratio, high compressibility and low bearing capacity, a series of geotechnical engineering problems are inevitably encountered when sea filling and land making are carried out and engineering facility construction is carried out, particularly engineering accidents such as necking hole collapse of a cast-in-place pile and pile position deflection are the most prominent, and construction period is often delayed and construction cost is increased steeply. Obviously, the stability degree of the soil layer around the drill hole in the tunneling process directly determines whether the pile-forming quality is good or bad and the construction safety is safe, and how to effectively ensure the stability of the soil layer around the hole so as to avoid hole collapse is a common problem in the pile foundation construction of the land reclamation area at present. In the prior art, a mud wall protection technology is usually adopted to keep the stability of the hole wall in the tunneling stage, namely, bentonite, water, a chemical treatment agent and some inert substances are mixed and uniformly blended according to a certain proportion and then injected into a drill hole through a pipeline system for circulating circulation, so that a layer of mud skin is formed between the hole wall and mud, and the mud pressure which points to the periphery of the hole and is applied to the mud skin by the mud is used for balancing the soil pressure (hole collapse inducing force) which is applied to the mud skin by the soil body at the periphery of the hole and points to the hole and is applied to the mud skin, thereby realizing the stable self-support of the soil layer. However, mud dado has some inherent drawbacks: a mud pit is built on site, a circulating pipeline is arranged, and the specific gravity of mud is adjusted, so that the construction site occupies more space, the operation flow is complicated and complicated, and the time and labor are consumed; once the proportion of the mud is not properly adjusted, the hole wall is difficult to form solid mud skin, the wall protection effect is poor, and a large hole collapse risk exists in the drilling and digging process; the mud circulation process can cause the construction site to be muddy, and great environmental pollution is caused; the mud retaining wall has higher requirement on the consistency of the mud, the mud is too thin, the slag discharging capability is low, and the wall retaining effect is poor; if the slurry is too thick, the impact function of the drill bit can be weakened, and the tunneling speed is reduced; the cost of the slurry is high, and if the bentonite is adopted for making the slurry, the cost price is almost the same as that of the cement.

The microorganism induced calcium carbonate precipitation solidified soil layer (microorganism soil fixation for short) has the characteristics of small construction disturbance, low filling pressure and good ecological compatibility, and compared with the traditional physical and chemical soil fixation method, the microorganism soil fixation method has the advantages of convenient operation, low cost, almost no generation of toxic and harmful substances and small chemical pollution to the surrounding soil-water environment; in addition, the viscosity of the used bacteria liquid and cementing liquid is low, so that the soil is easier to move and diffuse in sandy soil medium, and the soil-reinforcing and wall-protecting method has the advantage of being unique in the field of cast-in-situ bored pile soil-reinforcing and wall-protecting in land reclamation areas. However, the soil fixing range of the existing microorganism grouting equipment is very limited, and the solidification effect can only be generated on the soil body in a small range around a drill hole generally, and the hidden danger of hole collapse in the later period cannot be eliminated [ Shao Guang. In addition, in the existing microorganism grouting technology, both a bacteria culture substance and a solidified substance are injected into a soil layer in the form of solution, and the early solidified product at a grouting port hinders the migration and diffusion of subsequent solution, so that the solidified product cannot be uniformly and densely distributed among soil particles, and the soil layer is solidified to hardly achieve the optimal effect. Therefore, how to purposefully transmit the curing reaction substance to effectively avoid the situation that the former product obstructs the subsequent slurry migration, and how to precisely regulate the reaction aging of the substance to exert the optimal soil-fixing and wall-protecting effects is a difficult problem to be overcome by those skilled in the art.
