This paper introduces the general situation and the geological conditions of a certain construction project,through the schemes comparison,determines to adopt the deep-stirred soil-cement gravity retaining wall to make the supporting and water seal,and expounds emphatically its construction processes,construction points and quality control measures.
This article introduces some technologies used in the deep foundation pit of xiamen construction bank's building such as concrete bracing,anchor bar reinforcement,water stopping by propeller pile and concrete wall,construction monitoring etc.
The artificial dug pile building enclosure is adopted for the turning back depot in front of the Huanggang station of the Shenzhen metro. Outside the building enclosure, are provided the water stopping curtains of Ф800mm andФ600mm swivel injection piles.
Some synthetical technical measures are taken at last, for example, water guide, catchment, rainfall, wall bottom of pit, backfill back pressure sand wrap in basement part, etc. They make the foundation of basement be finished successfully. The writer suggests to take some practicable measures in order to strengthen vertical control of piles in construction of stirring piles sealing up curtain at the same time.
Objective: We prospectively evaluated the efficacy of water seal in the management of air leak after pulmonary resection.
Switch was made to water seal if the air leak was graded as "minor at expiration" or lower.
This procedure is referred to as "the water seal challenge".
The water seal challenge was attempted on POD 1.6±1.0.
While 45 patients (78%) continued to receive the water seal, the remaining 13 patients were switched to suctioning at -5 cm H2O followed by the successful second water seal challenge within 3 days from the first challenge.
Water percolation rates of the lysimeters were adjusted to one of three values, about 0, 5, or 20 mm day-1, during the cultivation periods of the first 3 years by periodically opening water stopping valves installed at the bottom of the lysimeters.
Although nicking of the DS DNA molecule is an essential step even in the normal intracellular replication of ?X DNA, the production and the sealing up of such nicks appear not to have any positive correlation with UVR of these phages.
After sealing up all the holes in the motor with either tape or hot glue, Vaseline is packed around the shaft.
Besides sealing up the holes in many of these earlier approaches, FOOD also puts them together to build a more secured system.
Sealing up operation lie in filling undug or leaking places with a sealing material or injecting liquid sealing materials inside the pipeline.
Thus, external and internal sealing up methods can be distinguished.
