Analysis of utilization of grout and grout curtains--Flaming Gorge Dam  Fetzer, Claude A. Denver, Colo.: Concrete and Structural Branch, Division of Research and Laboratory Services, Engineering and Research Center: U.S. Dept. of the Interior, Bureau of Reclamation, . RE: Grout curtain Focht3 (Geotechnical) 19 Feb 03 You can also stabilize the groundwater level outside the excavation by re-injecting the water from the dewatering wells into the areas where dewatering could cause problems.
jet or replacement—displacement grouting • the grout materials used are cement and water with some additive as indicated in table • jet grouting is the youngest of grouting techniques and consulting geotechnical engineers have begun to use it after the mids. • it is more expensive than permeation grouting, due to larger. Other articles where Grout curtain is discussed: dam: Construction techniques: metres ( feet) as a grout curtain. A corrugated blanket of clay extends upstream within the dam from the base of the core. Within the upstream and downstream cofferdams, partly of rockfill, much of the filling is of compacted sand. Filter layers separate the cofferdam filler from the outer layers.
between rock-mass characteristic, permeability, grout take and the closure criteria adopted for the curtain grouting. Fig. 1 – View of the dam: spillway under construction, right Middle Level Outlet discharging about m 3 /s (October ). Analysis on cores recovered from first and second phase of excavations in Doosti Dam shows that the specific rock mass quality in lithological units of dam foundation area decreases near surface and apart from the fault paths, increases in the depths. Table 2 shows RQD values for different parts of the Doosti Dam site. Grout curtain of doosti dam.

The Grout GROUT can be defined as a solution, an emulsion or suspension in water, which will harden after a certain time interval.
It can be divided into two main groups: a. Suspension Grout b. Liquid Grout or Solution Grout. Suspension grout is a mixture of one or several inert materials like cement, clays etc.
suspended in a fluid -- water. Results show without grout curtain around m3/s water seepages from dam and with the 70 m grout curtain depth, reduces to the lit/sec.

Curtain grouting of the foundations of concrete dams is most effective after completion of the dam, at a time when the full load is being applied to the foundation. Under such circumstances higher pressures may be used in grouting so as to assure maximum travel of grout in all directions along flow paths intersected by grout holes.
A vertical section through a concrete dam is shown here. The stored water is on the left and the grout curtain is shown in black, with the drainage curtain downstream of it also in black. An exaggerated example is shown at a concrete gravity dam where wide cracks in a foundation permit seepage to pass under the dam and emerge downstream.
Corps of Engineers 'Analysis of utilization of grout and grout curtains--Kortes Dam' -- subject(s): Dams, Grout (Mortar), Foundations 'Analysis of utilization of grout and grout curtains--Flaming. Dam grouting is a proven methodology for installing up-gradient and down-gradient barriers in dam foundations.
In this application, these barriers are often called grout curtains. This technique is employed where the rock formation beneath the existing or proposed dam foundation is so pervious that seepage problems are expected.
Wimbleball Dam in the South West of England. Historical Background – The Need for Change Over recent decades hundreds of dam cut/offs have been constructed in rock and alluvium by the injection of self-hardening grouts.
The plant, equipment, grout formulations, and injection procedures were very simple, and slow to evolve. CHAPTER 22 – DRILLING AND GROUTING Notes: 1.
Rates include all lead and lift for all materials. 2. The rates for drilling are inclusive of cost of taking out cores, logging, labeling and preservation of cores, maintained in serial order and painting depths on cores and on the core box, and protection of drill holes till final measurements.
3.The grout curtain for the tailings starter dam requi m of drilling and injection of 2, tonnes of cement. It was critical that the grout curtain be completed to the required performance standards prior to the winter rainy season to impound sufficient water for startup of the mill.
