Dewatering in deep excavation

In deep excavation under ground water table near adjacent structures and buildings that may affected by settlement, what is the remedial proposal?
We recommend to establish compensative wells directly to the adjacent structures to raise the drawn down water table.This process can rise ground water table under existing structures which can element settlement, structural engineer shall review the site and check adjacent structures prior to dewatering.

Differences between development length, anchorage length and splice length

1-Development length Ld It is the minimum length of a reinforcing bar that must be embedded or "developed" in concrete to ensure that the bar can achieve its full strength in tension or compression. 2-Anchorage length La The distance that the reinforcement extends from the point where the bars are no longer required to resist moments 3-Splice length LS The distance require to transfer the force from bar to another one to upload full presentation please download this https://drive.google.com/file/d/1layyDvTlJOLzo3jfoW4K5O5UEkgoEzgN/view?usp=sharing

KEYSTONE RETAINING WALL

Introduction:- Keystone is a mechanical stabilized earth wall MSEW which used to retain soil from one side, it's less cost than concrete walls. Material 1-Keystone Blocks 2-Fiberglass Pins 3-Geo-grids 4- Back-filling Material 5-Concrete pad Different type of Geogrid: TT045 can carry load till 45KN/m. TT060 can carry load till. 60KN/m. TT090 can carry load till 90KN/m. TT120 can carry load till 120KN/m. TT160 can carry load till. 160KN/m. Method Statement 1) Place HDPE Geogrids on top of the compacted soil. HDPE Geogrids are installed from the front on top of the fiber glass pins (which penetrates the grid) and from to back, Geogrids are fixed horizontally using a steel bars. 2) Lay down the precast concrete units on top of a PC foundation at a level that is a Minimum of 5% from the wall height and reach 10% (buried height) to prevent any lateral movement . 3) Put the layers of Geotextile. 4) Backfilling using fine gravel b...
