Title:

Process for Construction of Shallow Multidirectional Underpass Intersection by Box Jacking and Soil Nailing without Effect Existing Traffic

Value Proposition:

This technology provides the facility to construct the underpass intersection without disturbing the surficial traffic and also reduce the cost of construction and time. Not only this, the dropped underpass can be executed because of site and space constraint.

Summary Application:

The underpass intersection which  facilitates  construction of underpass in line with or parallel to the existing highway using box jacking method has not been found attempted anywhere in the world before. This invention also helps full to construct underpass at any desired location (below ground intersection) even at places where it is not possible due to site constraints

(i) A series of redlights in a short distances can be omitted after constructing the  underpass using the said construction methodology.

(ii) Shallow Underpass by box jacking in the alignment of road traffic (similar to metro) can be constructed without disturbing the live traffic.

(iii) Shallow pedestrian underpass can be constructed using this technique

Advantages:

i. No disruption to rail/road traffic.
ii. Safe and secured technology.
iii. Environmental friendly because less excavation is required.
iv. No involvement of crane & heavy equipment.
v. Less time required to complete the project.
vi. Less manpower & machinery are required
