Diaphragm Wall Construction (P-2)┃ऐसा दीवार का काम पहले नही देखा होगा‼️Anchor Grouting & Stressing

Diaphragm wall construction is very crucial for modern super structures like residential and commercial complexes with basements. These reinforced concrete walls provide the much required underground support and stability to the structure.
DIAPHRAGM WALL ANCHORING (Part-2) ┃ऐसा बेसमेंट दीवार का काम पहले नही देखा होगा ┃Anchor grouting & Stressing
In diaphragm wall construction, ground anchor bolts are used in order to link the structural and non-structural elements of the D-wall to the concrete. The process of casting these anchors into the diaphragm wall is known as Anchoring.
It involves anchor bolts, steel plates, sleeves and stiffeners to form the anchor on the diaphragm wall.
Anchoring ensures that these diaphragm walls are sturdy enough to keep these structures intact. Anchoring is one of the most important aspects of diaphragm wall construction.
Anchoring assists in transferring the tension and shear forces between these structural elements and provide lateral support to the diaphragm wall to sustain force from the top.
If anchoring is not done by diaphragm wall construction companies, then they have to increase the depth of the wall into the ground to almost double the size required.
Constructing a diaphragm wall without anchoring increases the cost of labor, the amount of concrete and steel used in the process, thus adding to the cost of the project.
In diaphragm wall construction, ground anchor bolts are used in order to link the structural and non-structural elements of the D-wall to the concrete.
The process of casting these anchors into the diaphragm wall is known as Anchoring. The Anchoring activity begins 7 days after the diaphragm wall panels are cast.
Anchoring process:
Anchoring is done post casting of the diaphragm wall. There are multiple levels of anchoring, with one anchor level in every basement. When the diaphragm wall cages are made, there are slots left open in equal distance on them. They are called anchoring sleeves. The distance maintained between them is ideally 5 meters. But the depth can be increased, given the quality of the soil the diaphragm wall construction companies are dealing with.
A drill rig is used to drill boreholes of 150 to 180 mm, at 15 to 30 degrees and the anchor tendon is put into the hole in the center. Upon completion of boring, the borehole is cleaned through compressed air. A low relaxation prestressed steel (LRPC) strand is inserted into the bore and the anchor is grouted.
The anchor head is then pre-tensioned by jacking after 7 to 10 days, and the anchor heads are set in place. The anchor is later distressed after the slab casting is done.
Equipments:
Equipments used are the advanced anchoring rigs, Casagrande C6, can drill up to 8 inches instead of the regular 6 inches, 4 of them, Long Boom Excavators, Conventional Anchoring Rigs.
