This rail system will be used for carting out spoils and bringing in additional liner plate. There is a Iaser that is housed in the back side of the bore pit.It is set in place daily and the elevations are checked on site by our Forman. We will grout the outside of the liner plate using a concrete grout pump and heavy-duty grout hoses(additional information will be included in another summary regarding grout).The liner plate has grout outlet holes built into it. We are hoping to get b' of tunnel completed per day. We will grout the outside of the liner plate at the end of each shift while under the railroad "Zone of Influence". Grouting while not under the tracks will be done as needed_ This could be daily to weekly based on ground conditions. If the ground conditions are stable,there is no reason for excess grouting. Once the distance of the bore is complete with the liner place and all outside grouting is complete,we will install a host pipe that will carry the actual storm water.This host pipe will be installed using a bore machine power pack and hydraulic cylinders for pushing the pipe in joint by joint. It will go into the liner plate tunnel along a rail system in the bottom. This rail system is comprised of angle iron that is welded to the bottom portion of the liner plate. It is spaced so that the steel casing can slide along these rails and be pushed into the tunnel.These rails are on grade for the flow.The annular space between bottom of the liner plate and top of rail is grouted before the casing is installed. (All annular data is in another description.) We use the same laser that got us through with the liner plate to guide the steel pipe installation. This is how our grade will be achieved and maintained. The pipe joints will be connected by building bell ends to the casing and then connecting the bell to spicket with welding. These welds will have a tensile strength of 70,000 psi. (There will be an additional description for the welds.) The pipe that is being produced has a submittal form in these documents. Our connections points will not lessen the original strength of the material. Once all host pipes are installed the will be jacked down to hold them in place.These jacks are created by cutting separate sections of steel casing 1/3 the circumference the installed casing.Then there are legs that are welded on the arcs that brace against the installed liner plate. These legs are made from steel tubing and all thread material. This is to allow adjustment while locking the pipe into place. These j acks are installed from end to end of the bore to secure and lock in the grade.These jacks will be installed every 10' along the tunnel. Finally, all pipe will be grouted in between the liner plate and outside of the host casing. (There is another detailed description that covers the grout .) Both ends ofthe tunnel are then sealed up with the wooden planks, see the mitigation plan for wooden planks. The tunnel crew moves out and takes their equipment with them. Tunnel Grouting Information The grout pump is a Mayco LS-60TD. I will include pump specs and dimensions sheets. The field procedure is pumping grout through hoses and into the grout ports. When the grout comes out the end of the liner plate, where the tunnel is currently stopped, we plug the Iow E grout port and move up repeating the process until the full outside ring has been grouted. As the tunnel progresses, we add additional hoses to pump the grout the required distance. The space between liner plate and steel pipe is grouted from downhill using same grout pump and schedule 40 pipe_ There will be three runs of schedule 40 pipe to complete ft annular grouting. These runs will be space 45' apart to verify enough grout makes it through all the pipe and fills all annular space. Grout is foamed to double the volume. Outside liner plate 15 yards or grout that is foamed to 30 yards. Annular space is 67.5 yards of grout that is foamed to 125 yards. Grout ports are outlined on the Liner Plat e Lay Schedule attachment. We will pump grout at the end of every shift while under the zone of influence _ While out of the zone we will see how conditions look and assess how often grout is needed. If it is daily, we will grout daily, if it is not needed on that regularity then we will wait a few shifts and then grout. More will be known once the excavation begins. Bulkhead A bulkhead will be placed at the front of the tunnel while we are not working.This bulkhead is comprised of wood and rebar_ The wood will be placed first . It is stacked starting at the base of the tunnel and goes to the top.This wood is 12" wide by 2" thick and will be different lengths based on how far it much reach (smaller at the top and bottom and largest in the middle). The wood is placed in front of the tunnel liner plate using the lip to brace against. From there we will install cross sections of rebar to extra fortify these wooden planks. This bulkhead will be installed at the end of shifts and on weekends while we are notworking. When the bulkhead is in place,we are able to pump our grout onto the outside of the liner plate. The grout will fill all voids left from excavation between the liner plate and existing soil. The bulkhead also acts as a dam during the grouting, stopping the grout from entering the tunnel. i Excavation Methods We will be using machine excavation to dig the bore pits. These machines will dig down to grade and level off as best as possible. Final grade of the floor in the bore pit can be done with I" rock if needed. The tunnel alignment is controlled by hand.As we hand excavate,we maintain the trajectory following the laser path. We treasure, dig and then install the liner plate.The liner plate installation starts at the highest point in the tunnel and then we work our way down on the sides competing the ring. Once a ring is complete, we repeat the process until the bare is complete.Thetunnel linerplate acts as the shield in the tunnel. The excavation in front of the liner plate is kept to a minimum. Depending on the ground conditions we will be excavating between 21" and 23" in front of existing rings for the next installation. This is to allow room for the liner plates to be installed properly and also to allow the bulkhead installation at any point if needed. The distance from the top of our liner plate to the bottom ofthe track will be 8.25`or greater. The carrier pipe will run inside the liner plate and be 9.2' from the top of pipe to bottom of rail r r s, 1U C3 lii 66 t � 3 F i a ui F. �sF'yi •4 C kv In � a w _ 4 Stfuc4"M CWWAINHO 8 $®p 2-rIn"96 Croat Plato 1. piojocZ Crly of Fort 3Pd•:l1rh vie-AOFfi S,Mth l)rAi'),3tjs! iw,)rov Ph,-zz P 28 - 5L.� ti-rtif.to Fnrt Werlh, Texas 11.
