BOEING EVERETT SECTION 34 11 10 <br /> NEW RAIL SPUR TRACKWURK-GENERAL REQUIREMENTS <br /> WORK ORDER 10•305 <br /> 2. Remove the dutchman pnor to anchoring and when lhe rail temperature results in a <br /> calculated closure o11he rail gep. <br /> F. Instoll the reil end clamp lo produce zero lhermal stress in the reil at 100 degrees F temperature. <br /> Range is plua 5 degrees F to minus 10 degree F. <br /> 1. Submit the details of theae procedurea br anchoring C1NR to Boein3 Construction Manager <br /> as paA of the Working Drawinga specified in Paragraph 1.04A of this Section. <br /> 2 Zero thermal stress in CWR may be echieved by heating, cooling, vibratinp or pulling lhe <br /> rails, or a combinalion thereof. <br /> 3, When zero thermal slress is obtained, begin anchoring immedialely. <br /> a The stresa within the reil shell remain within Ihe specihed zero thermal stress range <br /> during installation of joints. <br /> 4. Methods for artificially obtaining±ero thertnel stresa shall be subject to Boeing Construction <br /> Manager's review prior to use. <br /> 5. Once zero thertnel stress has been obtained,meintain the cortect rail gap unlil the rail is fully <br /> anchored. <br /> 6, Vibratore used for relieving intemel rail stresses shall be of a type nol to demage lhe CWR. <br /> 7. CWR shall not be struck with objects that might damage lhe rail. <br /> G. The installation of rail anchoring es described on AREMA Part 4 Track Construdion,is nol required, <br /> anchoring is provided by the longitudi�al reslraint cheracteristics of the reil fbstening spring clip <br /> supplied with the rail fizalion anchor plales or fastenere. <br /> 1 The fastening tampereture of eech rail in a track shall be within the allowable range specfiied <br /> herein end shall be wilhin 5 degrees F of the opposite rail anchoring temperature. <br /> 2. Prior to placing omlrack equipmont on newly laid rail, secure Ihe rail in a manner thal will <br /> prevenl damege to the rail and track material. <br /> 3 Move equipment over partially secured treck in euch a manner as to prevent damage lo <br /> structures and trackwork malenels. <br /> 4 Temporarily tasten newly laid reil on baliasted treck and embedded track et the specified <br /> gauge at every ten�eet on tangents and on curves having a radius greater lhan 1000 feet. <br /> 5 Remove rail fastening spnng clips at the time of CWR lemperature adjuslment. <br /> H When a joint is made between clamped CWR strings,the rail gap shail be as specified. If the gap is <br /> nul within the recommended tolerences for the joint, unclamp the CWR strings for 300 feet each <br /> side of the raVl gap, and read�ust each CWR string for 300 feet within the specitied zero thertnal <br /> stress temperaW re range Reclamp the CWR betore lhe�omt is made. If the recommended rail gap <br /> cannot be oblained in thls menner, unclamp one ot the stnngs entirely, move, length adjust and <br /> reclamp so that the specdied rail gap is oblainetl. If lhe Contrector elects to use a mechanical <br /> means of adjusting the rad for clamping, the melhod and equipment proposed shall be sub;ect to <br /> review by Boeing Construction Manager. <br /> Permit Set � �� ��� 9 <br /> September 2J 2C11 <br />
