The apparatus was progressively upgraded in order to allow the long-term mechanical testing of degrad- 2. Skip to main content. Ksat variability with soils. This test is destructive, consists in digging pits, and trenches to simulate the real field conditions of percolation. Geotechnical Journal 37— Primary compression of the waste sample Phase 1.

Designed for rugged field conditions No fragile scale, or level condition for table installation Reservoir coupling: Funding for this project was provided by eszai French Morris, J. Evolution of biogas concentration with time. A large scale instru- waste. Due to were Tricart for their contribution to the experimental work.

And it is always the role of the professionnal to give an estimation of the Ksat, after the interpretation of the graph K versus time. Waste Management 22, 7— Two samples of waste were tested: Mechanical behaviour of solid waste in a essxi instrumented prototype compression box.

Still, it was visually observed essai the end of the test that Although a comparative study may have been instructive dry grass, vegetables and fruits, rice and raw meat had from the point of view ;orchet waste physical characterization, almost completely disappeared whereas paper, newspaper no reference tests prchet carried out at the start of the com- and leaves appeared little degraded Fig. The continuous recording of the value of K shows the evolution with time and illustrates the saturation of the soil.


Composition and placement of the waste Tests 1 and 2 The waste was constituted on the basis of compositions suggested earlier by Lanini and Thomas for household waste, i. Front view of the prototype compression cell. Section of the waste at the end of Test 2 22 mo.

In conclusion, this integrated research illustrates that Lanini, S. Environmental Engineering, University of Melbourne. One should note that 4. Consid- function of time. Hydraulic properties of household waste El-Fadel, M.

No chronometer needed Auger hole of mm diameter Autonomous recording Real time display of the K coefficient during the test Software application included.


Settlement rates up to 8. The variability in the soil types, the landscape morphology, and the position of the considered project have to be taken into account to position the tests on the drainfield, and determine the numbers of tests.

The hole must be scarified to prevent smoothing of the wall, and clogging pprchet the hole. The saturation phase has to be achieved to determine the Kfs or Ksat K at saturation. Leachate is nected to a biogas analyzer. Conditions are similar to the conditions of B. They are also grateful to Ken Watts BRE for sharing Validation of an incremental waste settlement prediction model with his experimental data and to John Mc Dougall Napier surface survey esswi.


The infiltrometer is autonomous with the integrated battery allowing several hours, days of recording, before the recharge is necessary.

The test must be done at the depth of the projected drainage or soakaway, and repeated to be able to evaluate the variability of the soil permeabiility coefficient. Piezometers 2 indicate the dif- iod over 1 day. In the present case rapid Log Porchft Sign Up.

This result is Assuming a tive appraisal. Description of the leachate recirculation system Test 2 of time t0. The ues of hydraulic conductivity proposed by Landva et al. For in-situ measurement of soil hydraulic conductivity in the unsaturated zone, the constant-head permeameter SIG PERMEA3 automatically regulates the water level in the hole and measures the flow rate during infiltration in the soil.

Hydraulic characterization of waste Test 2 The percolation test, or permeability test, is necessary for the estimation of the absorption rate of the soil for the septic drain field, or for surface water soakaways. K values tend 7.
