35) High pressure jet grouting with new twin-tube method was employed in the construction of a new drydock and the mucky soft soils in the site were successfully treated to prevent water seepage.

36) Research conclusions: The technique and result of two-shot grouting were not good as that of cement mixture pile(http://Sentencedict.com), but it had features of simple operation and low cost.

37) The effects of different amount of water and pisolite on the workability and mechanical properties of pisolite grouting material (PGM) were studied.

38) First, efforts are made to explore the support mechanism of the ductule high pressure grouting technology in the excavation of soft-fracture wall rock.

39) A method of embedded pipe and outlet box was adopted in the joint grouting system of Wanjiazhaidam.

40) The feasibility of slope reinforced by grouting is proved and multistage grouting ( PG ) is put forward.

41) The pipe is complete enwrapped by cement after grouting, not loose and rupture when pulling wire.

42) Using such repair, chemical grouting treatment strategies and measures to solve the tail pipe, joint and cracks of the runner room.

43) Through studies, the mixed solution consisting of the calcium acrylate and the magnesium acrylate is proved and recommended as a good material for grouting.

44) The influences of the water level and siphonage on the water volume to replace the cement fluids in grouting hole are analysed.

45) In the design of the impermeable curtain grouting engineering, high - pressure cement grouting with orifice - closed adopted.

46) Based on randomized block design for single factor, the effect of Jin Nuofeng on flag leaf photosynthesis characters, grain grouting characters and yield of the winter wheat Shaannong 981 was studied.

47) "Elastic epoxy", as a strengthening and solidifying grouting material, is composed of epoxy resin, furfural-acetone resin, plastisol, additives and curing agents.

48) Introduce the grouting reinforcement method of the soft rock of coal bin and fall area and analyze the fall reasons and the grouting result.

49) For aluminum cement, through adding fly ash, the cost of anchor engineering can greatly be reduced under eligible primary compressive strength of grouting material.

50) By conducting site curtain grouting test, curtain grouting method, technical parameters and resource allocation are studied for this kind of geological formation.

51) Initiated in China, Claybank split-off grouting is a new technology achieved success in dealing with hidden troubles in dykes.

52) The procedure includes preparing, boring, setting pipes , manufacturing serous fluid and grouting etc.

53) When grouting gallery of depth-curtain, lining and consolidation grouting to full-face of the gallery is necessary to meet the needs of the grouting pressure.

54) After grouting of drill hole at here, the mining production has been recovered.

55) The grouting reconstruction technique of lower confining bed can be water hazard from coal floor.

56) In the technology of flooding control, the measure of grouting for stopping up water before or after excavated is adopted based on the amount of Inflow.

57) After pressure grouting on pile tip, elastic working range of piles will be extended and be in favour of pile to bear repeated loads and dynamic loads.

58) The main purposes of the second stage artificial cooling in concrete arch dam are to make transverse joint grouting possible, and decrease the dam's temperature stress.

59) However , through the new technology of chemical grouting of backfilling, the water yield falls to 2.
