A kind of recharge well with filter layer exists in recharge engineering of Wanghe groundwater reservoir in Laizhou city of China. During artificial recharge of groundwater, layered sediments will silt in the surface layer of recharge well with filter layer. Through doing vertical permeability test of combined soil specimen of silt and sand, we simulate permeability influence to filter layer of recharge well with filter layer during artificial recharge of groundwater. The test indicates that silt reduces permeability of filter layer and recharge capacity of recharge well with filter layer. Also we discover that there are errors in theoretical calculated value of coefficient of permeability for combined soil specimen by the formula of equivalent coefficient of permeability in layered soil, which need to be corrected.

Permeable form can improve the quality of the surface layer of concrete and can enhance the durability of concrete structures. In this study, the improvement and its evaluation for the surface layer of concrete placed with permeable form were investigated. For these purposes, accelerated carbonation test, chloride ion penetration test, air permeability test, rebound hummer test and water permeability test were conducted using the concrete specimen. As a result, it was found that the air permeability correlates the carbonation depth, chloride ion penetration depth, rebound number and water permeable volume of concrete. Moreover, the possibility that the improvement for the surface layer of concrete can be quantitatively evaluated by air permeability test was shown.

The development of a specially designed triaxial permeameter for the measurement of the coefficient of permeability of deformable unsaturated soils is presented in this paper. The triaxial permeameter makes it possible to directly measure the coefficient of permeability at various combinations of net normal stresses and matric suction values. The volume change of the soil specimen during the permeability measurement can also be monitored. The performance of the permeameter is demonstrated for a group of tests conducted on slurried specimens of a silty sand.Key words: unsaturated soil, coefficient of permeability, triaxial permeameter, volume change.

Recharge Well

Recharge well with filter layer is a sort of valid recharge facility in groundwater reservoirs, which is constituted by recharge well and recharge pool. The main problems of existing recharge well with filter layer are analyzed in this paper; the main reason of these problems is concluded as the defective design of the wellhead structure; the optimal outer design method of recharge pool is studied. In order to increase single-well recharge volume, improve anti-silt and anti-rush capability of recharge well and save sand-gravel materials, geotextile material and hard wall material are adopted; a new sort of geotextile recharge well with filter layer is developed. The theoretical formula of single-well recharge volume is deduced.

In the Marchfeld - a region of about 1000 km2 in eastern Austria - groundwater is used intensively for irrigation as well as for industrial and potable purposes which has led to a considerable decline of the groundwater table. As a countermeasure the Marchfeldkanal Project was started in 1984 in order to secure the important groundwater reservoir in this dry area. The Marchfeldkanal system was designed as a multi-purpose project, with the aim of providing external water to the region. Beside replenishing the groundwater by artificial recharge now surface water is available for irrigation. Further effects are the improvement of surface water quality and a new protection against floods. It was set store to a very natural design of all parts of the system, in particular of the watercourses. So the Marchfeldkanal System has become an appreciated recreation area. Presently, the system has been completed and three groundwater recharge facilities are operational after periods of testing operation. The next step will be the selective infiltration of surface water, which is withdrawn again by a drinking water abstraction of a local town.
