aFigure 18 illustrates water seepage due to extended waterponding on the slab while Figure 19 illustrates the case where clogged drainage in the wet-features caused excessive hydrostatic pressures against the horizontal structure. 图18说明水渗流由于延长waterponding在平板,当图19说明案件时,阻塞的排水设备...
5, it can be seen that the seepage scope is spindle shaped around the cracks; meanwhile, the penetration depth along the crack direction is much larger than that in the vertical to crack direction, which reflects the permeability of cracked concrete is greater than that of sound concrete. ...
Based on the motion law of equal-width slit steady flow,by analyzing the characteristic of the concrete face slab cracks and its seepage configuration,the ... RJ Wang,LU Hai-Dong,LI Yan-Long - 《Journal of Water Resources & Water Engineering》 被引量: 5发表: 2008年 WET (PLASTIC) AND ...
PVC waterstop, being embedded in the concrete joints, acts as a continuous watertight diaphragm to prevent any seepage of liquids in constructions joints which are subject to hydrostatic pressure. It is designed for expansion or contraction joint; meanwhile, it can accommodate lateral and transver...
5. If a concrete base or slab (sometimes called a ptuap block or pump pedestal) is constructed around the top of the casing, it shall be free from cracks, honey- combs or other defects likely to detract from its watertight- ness. The joint between the base and the annular seal must ...

Upstream connection: guidewater flow smoothly into the gate chamber, protect upstream riverbed and Banksfrom scour, and have anti-seepage use. Downstream connectingsegments: the main function is to eliminate the seepage flow through the gateand the two Banks. 3. The influence factors ofbrake hole...
defects, suchaswaterseepage, spalling concrete, debonded floor and wall finishes, corrosion of metal space frame structure and windows, delaminated waterproofing membrane androofponding,would be far more substantial than those expected in the TFS. ...
