Impact of the basin runoff on the parameters eksfiltratsiynyh trenches

Boshota V.V.

The paper presents the results of an analytical study of stormwater exfiltration trench's (ET) parameters depending on the value of the basin area. These results are obtained with an improved method of hydraulic calculation of ET, taking into account the temporal dependencies of filtration area and hydraulic gradient of seepage flow at the outlet of trench. A graphical and analytical expressions for determining the dimensionless area and volume control coefficient of ET depending the value of the basin's area are obtained. Increasing the basin's area leads to an increase in the dimensionless area of ET, slight decrease of the volume control coefficient, increase the critical duration of the storm and the time of complete emptying of the trench.

Of inappropriate use of the appliance VS Syralyeva for determining the filter sand in BS B -23 B.2.1 : 2009, and the need for non- placement " draining " sand layer at the base of pavements roads

Litvinenko A.S.

Years of laboratory filtration coefficient determination experience of sandy soils by use of device ‘КФ-ООМ’, proves this apparatus to remain the best in his grade, and needs no other device to replace for any laboratory test. In addition, it needs to be mentioned, that the use of sandy ground and crushed stones at the base of road construction has rather greater negative influence on its durability and reliability, than protects the soil basis from the undesirable moistening.
