color="#000000" /><P>HEADWALLS <BR><BR>Headwalls or wingwalls improve the flow of water into and out of conduits, provide anchoring support for the pipe and prevent dislodging under excessive pressures, control erosion and scour resulting from high water velocities and turbulences and to prevent adjacent soil from sloughing into the waterway opening. Headwalls are necessitated by limited space and poor soil conditions. </P> <P>The inherent flexibility and porous nature of gabions address the design concerns of headwalls which must properly dissipate the energy of water flow, withstand or relieve soil and hydrostatic pressures, and in areas prone to such seasonal changes, withstand the effects of frost action acting upon the soil. preclude detrimental heave or lateral displacement resulting from frost action. </P> <P>CULVERT OUTLETS <BR><BR>The outlets of pipes and lined channels are points of critical erosion potential. The velocity of water conveyed through pipes or conduits often exceeds the capacity of the receiving basin or channel to resist erosion. </P> <P>To prevent scour at these sites, protect the outlet structure and minimize the potential for downstream erosion, a flow transition structure is needed to absorb the initial impact of flow and reduce the speed of the flow to a non-erosive velocity. Aprons constructed from gabion mattresses placed at these outlets will absorb energy to calm turbulence and slow the velocity of the discharged flow.</P> <P>&nbsp;</P></font><hr color="#000000" />If you want to see more news, Please <a href="../knowledge/">Click Here</a></DIV> </DIV> </div> </div> </DIV> </div> </div> <DIV class=footerAll> <DIV class=footerHTML> <table width="100%" border="0" align="center" cellpadding="3" cellspacing="0" class="language"> <tr> <td><a href='javascript:translator("en|en")' ><img src="../images/ico_english.gif" width="20" height="14" border="0" align="absmiddle" /> English</a></td> <td><a href='javascript:translator("en|de")' ><img src="../images/ico_deutsch1.gif" width="20" height="14" border="0" align="absmiddle" /> German</a></td> <td><a href='javascript:translator("en|es")' ><img src="../images/ico_espanol.gif" width="20" height="14" border="0" align="absmiddle" /> Spanish</a></td> <td><a href='Javascript:translator("en|fr")' ><img src="../images/ico_francies.gif" width="20" height="14" border="0" align="absmiddle" /> French</a></td> <td><a href='javascript:translator("en|it")' ><img src="../images/ico_italino.gif" width="20" height="14" border="0" align="absmiddle" /> Italian</a></td> <td><a href='javascript:translator("en|pt")' ><img src="../images/ico_portgues.gif" width="20" height="14" border="0" align="absmiddle" /> Portuguese</a></td> <td><a href='javascript:translator("en|ja")' ><img src="../images/ico_japan.jpg" width="20" height="14" border="0" align="absmiddle" /> Japanese</a></td> <td><a href='javascript:translator("en|ko")' ><img src="../images/ico_korea.jpg" width="20" height="14" border="0" align="absmiddle" /> Korean</a></td> <td><a href='javascript:translator("en|ar")' ><img src="../images/ico_arabia.jpg" width="20" height="14" border="0" align="absmiddle" /> Arabic</a></td> <td><a href='javascript:translator("en|ru")' ><img src="../images/ico_russia.jpg" width="20" height="14" border="0" align="absmiddle" /> Russian</a></td> </tr> </table><img src="../images/payment_methods_01.gif" width="179" height="28" /> </DIV> <DIV class=sayu align="center"> <div align="center" style="padding-bottom:15px;"><span class="footerHTML"><font size="+0"><img alt="" src="../images/tr.gif" />&copy; 2010 <a href="http://www.gabions-china.com/">Gabion</a> - Anping Sun Gabion Co.,Ltd Telephone:<b>86-318-5289996</b> Email: <a href="mailto:sun@sun-wiremesh.com"><b>sun@sun-wiremesh.com</b></a></font></span></a></div> LINKS:<A href="http://www.jtsteelgrating.com/">Steel Grating Fence</A>, <A href="http://www.gabion.cc/">Gabion</A>,<A href="http://www.screenship.com/">Screen mesh</A> </DIV> </DIV> <marquee height=1 width=5 SCROLLAMOUNT=3000 SCROLLDELAY=20000> <a href="http://www.gabionychina.com/" target="_blank">gabion</a>,<a href="http://www.gal-wire.com/" target="_blank">Galvanized Wire</a>,<a href="http://www.shineyondgabion.com/product-273-Gabion-Box.html" target="_blank">Gabion Box</a>,<a href="http://www.gal-wire.com/" target="_blank">galvanized iron wire</a>,<a href="http://www.shineyondwire.com/product-274-Electro-Galvanized-Wire.html" target="_blank">electro galvanized wire</a>,<a href="http://www.shineyondwire.com/product-283-Straight-&-Cut-Wire.html" target="_blank">Cut Wire</a>,<a href="http://www.shineyondwire.com/product-275-Armoured-Cable-Wire.html" target="_blank">Armoured Cable Wire</a>,<a href="http://www.shineyondwire.com/product-282-PVC-Binding-Wire.html" target="_blank">binding wire</a>,<a href="http://www.shineyondwire.com/product-277-Black-Annealed-Wire.html" target="_blank">annealed wire</a>,<a href="http://www.jtsteelgrating.com/" target="_blank">steel grating</a>,<a href="http://www.shineyondwire.com/product-273-Hot-Dipped-Galvanized-Wire.html" target="_blank">hot dipped galvanized iron wire</a>,<a href="http://www.pr-welded-mesh.com/" target="_blank">welded mesh</a> </MARQUEE> </body> </html>
