In this article, the author introduces some effective technical methods in many aspects in the construction of manual - excavation & grouting pile of Guang Dong Development Mansion such as passing through the soft soil layers, draining off water over construction, confirming of bearing stratum and embedding rock, quality control of concrete of pile core. The technical methods are adopted to ensure the construction quality of the pile foundation.
The technology of vibro-compacted g ravel pile is of reliability,practicability,simpleness and rap id speed of construction and less investment, it is an effective technical measure for treatment of soft foundation.
It analyzes formed causes of mass concrete cracks from heat of hydration、internal-external bonding condition、external temperature and plastic shrinkage of concrete, and introduces effective technical measures in construction to reduce or avoid generation of cracks.
Polygonum viviparum + Carex rigescens + Kobresia bellardii) in the Luya mountains showed that it could release the characteristics of spatial pattern clearly and was a very effective technique.
Together with the cost-effective technique-Hbr display were developed in 2000.
The phase trajectories of the dynamic system are investigated using qualitative and numerical analyses, and an effective technique for searching for a physically comprehensive autowave solution of the problem is proposed.
An effective technique proposed earlier (Acoustical Physics 45 (3) (1999)) for estimating the kinetic and potential energy, the loss coefficient, and other energy characteristics of a vibrating elastic structure is improved and tested experimentally.
An effective technique is suggested for calculating the binding energies and envelope functions of the shallow donor states in type-I heterostructures with narrow wells and barriers.
26A4 should also be an effective technology for greenhouse gas CO2 fixation and/or conversion into industrial raw materials.
Therefore, treating grazed pasture soils with an FPS of DCD is an effective technology to mitigate N2O emissions from cow urine patch areas in grazed pasture soils.
This study shows that installation of filtration units is a low-cost (less than 6% of total cost) and an effective technology for controlling pollution at the source.
An effective technology for their processing, which makes it possible to obtain high beneficiation indicators due to regulation of the energy state the disperse system and subsequent weak electrochemical effects on the flotation pulp, is developed.
An effective technology for large-scale production of parts from this alloy (bolts, screws, rivets, etc.) is suggested.
