| Abstract: | Trenchless pipelaying is a technique making use of drilling or tunneling to install or replace piles under the roads or railways without digging the surface Based on several cases done by authors,the key steps for drilling and pipe installation are discussed in detail Some innovations in design and construction of the trenchless projects such as developing new types of bits,protecting aparatus for flexible drilling rod and automatic control instrument for direction drilling are presented in this paper |
| |
| Keywords: | trenchless guided drilling angle of tool track |
