device 1 would be altered to conform with the respective sheet pile interlock and sheet pile front face 14 will be shaped to guide and retain the sealing compound and conferred to the back face 13 will be a shape adapted to a desired sheet pile type and interlock it should be noted that such a device in accordance with the present invention does not need a special centering feature during the device 39 s forward movement through a sheet pile interlock the feeding chamber 30 see fig1 and 2b is delimited on its front side i e the side lying in the travel direction of device 1 by the flat vertical back face 23 of the sliding block 20 the port 12 opens into the chamber 30 in order to maintain chamber 30 completely filled with sealing compound of a pasty to plastic consistency depending on the amount of sealing compound required to maintain a consistently filled chamber 30 there are several possibilities the two most common methods are either a reservoir for the sealing compound or a feeding line which is moved together with the translation carriage not shown of device 1 at the top of chamber 30 device 1 shows a completely empty hollow space which corresponds to chamber 30 of the interlock and which remains closed in the upward direction by the device 1 wall defined by the passage bore 12 for injection of the sealing compound the feeding chamber 30 ends near the front of the sealing compound distributing chuck 40 see fig1 and 2c fig2 c shows the profile 44 which has been selected as a function of the shape and extent of the layer of.
