Most proposed sewer bursts are manhole to manhole but at times it is necessary to extend the burst through an intermediate manhole The success of this additional length is dependent on the following conditions The intermediate manhole must be prepared to provide as little resistance as possible In some cases a larger overcut will be necessary to provide additional annular space to reduce new product pipe friction If the manhole is to be passed through the invert must be removed and enlarged to prevent the hammer expander from rising in the manhole and adding a speed bump Figure 11 Figure 11 Intermediate Manhole The use of bentonite is always recommended as a method to increase the burst length regardless of the host pipe diameter See Bentonite Uses pg 18 Bursts performed in similar conditions may give an indication of the total length expected Documentation is recommended for each bursting project This information is valuable for later reference in job planning Contact a TT Technologies product specialist for information on bursting projects completed worldwide Expander Types A REAR EXPANDERS Rear expanders slide over the main body of the GRUNDOCRACK bursting tool and are held in position by the hammer s flared end Figure 12 The PE pipe is fixed to the rear of the expander by one of the following methods 1 Rear Threaded Expander The supplied PE link is first fused to the PE train The expander is
