This article is to discuss construction process and craftwork of CFA drilling and cast-in-situ concrete pile. It is described the advantages, material requirements, work condition and reason & control measures for common quality defaults of this type of pile, which also analysis the construction and quality control process of this kind of pile.
Introduced concrete parameter that fit for shovel of tuber digger in different area and different working condition, discussed the influence that different parameter produced on potato digger, established main technical parameter of digging shovel.
It introduces performance and characteristic of gypsum block,and illustrates construction of it from construction preparation、working condition、process flow、quality requirement and transport,which to make gypsum block can be used in different buildings and improve benefit of enterprise.
From the angle of traditional manually execavating hole and grouting stake,combining with complex construction geological situation and badly spot circustances,the paper depth analyzes the working condition,construction technology feasibility and circumstafial factors,proposes the practical econmical construction plan,and effectvely solves the difficult problems under construction.
In view of the underground mining of Xinqiao pyrite mine, when adopting the back filling method, there were such problems as high loss rate of ores, poor operation condition, spontaneous combustion of the mined ores, and difficult control of ventilation and ground pressure, thus the sublevel open stope filling method was proposed.
The system played an important role in the precipitation enhancement,drought monitoring,operation condition identification,operation timing,cloud tracing and comprehensive effectiveness evaluating. The system improved not only the efficiency,scientificity,objectivity and systematism of seeding operations,but also the effectiveness.
Through analyzing the data of casing failure wells, the causes of casing failure in the fracturing wells are compared analytically, by which theoretical bases are provided for preventing casing failure under special operation condition.
The working conditions for CE-FA separation are as follows: operating voltage, 10 kV; running buffer, 67 mmol·L-1 phosphate, pH 7.4.
Equations are derived for filtration under unsteady-state and steady-state working conditions of wells and galleries.
Each of the cells represents a three-dimensional vortical circulation of the gas, and this causes a change in the working conditions of the nozzle.
The article discusses weakly twisted flows of an ideal gas with arbitrary thermodynamoc properties in a supersonic nozzle with a central body, under super- and subcritical working conditions.
Under the cyclic working conditions, the so-called "critical power" load, which is high enough but does not lead to a refusal so far, enabling one to perform the maximum amount of useful work, appears to be the most effective.
The flow field of a working point was solved by multiple calculations and the actual working condition was gradually determined.
Conclusion: Experimental results comprise evidence that MCI patients have higher degree of functional connectivity between hemispheres and in hemispheres during working condition.
