Introduction Technology that covers methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.

Or

In simple words it’s a

subsurface construction works where fewer trenches or no continuous trenches are required to be dug.

Slide5

Trenchless Construction Methods

Pipe Ramming and Pipe Compaction

Microtunneling

Horizontal Directional Drilling (HDD)

Slide6

Pipe Ramming and Pipe Compaction

PIPE COMPACTION:

This method forms a bore hole by displacing the soil

radially

outward rather than removing spoil. Usually used for pipe having small

diameter.Used

in soft to medium hard soil.

Limitation:unreliable

and

unguide

PIPE RAMMING:a pneumatic tool is used to hammer the pipe or the casing into the ground while the excess soil from creating the borehole is removed to the surface. 1) ramming tool drives steel pipe into ground 2)pipe inserted can be open or closed 3) the spoil can be removed by auger, water jet or compressed air This method is generally used in soft to very soft clays, silts and organic deposits, sands above water table,and soils with cobble,boulder etc.

Slide7

Microtunneling

Five independent systems are incorporated into a

Microtunnelling

system are as follows:

(1) Microtunnelling Boring Machine (MTBM)

(2) Jacking and intermediate Jacking system

(3) Spoil removal system

(4) Laser guidance and remote control system(5) Pipe lubrication system

Most machines have cameras set up to give more information.

Diameter range is from 10in to 136in
