Rock bolt pull out test

[@cesarpalma5487]

Well that test is already wrong, first you need to make sure no shorcrete is around holding the anchor because the moment you begin stressing the anchor you won’t pull on the grout alone but the wall itself. Therefore your reading will be wrong. The sole purpose of this test is to make sure the grout ( cement mix) has the right water to cement radio, so it reaches the desired strength. Some test have and ultimate pull of 2000psi or more depending of the length of the hole. The more you pump on the hydraulic jack the more pressure is put on the anchor. They are using their measuring tapes to measure the moment of the anchor as it gets stressed. Usually we have dials that are placed on the metal plate in the front that gives us the readings like 0.010 in 100s of an inch

Can you please tell how much load should be applied on bolt and calculate the ultimate capacity of it?

[@bridgeconstruction_irwansyah]

good video DP

[@localconstruction1768]

Good work

[@Onesteptohelpothers]

Helpful video please provide calculations of deflection how to calculate

[@rupeshkumarpajiyar8252]

Can you please tell me the process to know the maximum pull-out load carried by rock bolt?

[@dpblogs1609]

it depends upon capacity of machine 30 T,50 T, 80 T

Ye apne India mei kaha pe kiya hai ?? Konsi company ne kiya hai. Can u please provide details.

Grouting krne ke kitne din baad testing krte h?? And what is the specified load or displacement??

[@ranbeersinghbuthyal4929]

28 din baad

[@hanifullahkhan2993]

What is the working load? If rock bolts length is 3m Rock bolts dia is 25mm Rock: very hard

[@dpblogs1609]

AFTER 28 DAYS

[@ranbeersinghbuthyal4929]

Hum n b kiya hai aisi

[@malviyageo11]

What is the code to perform this test

Detail me nai bataya sir

[@tojohidekitojo5703]

small $job 😁🤗🤗🤭🤭🤭

[@farhanhafiz6088]

No proper explanation.. Which procedure you are using I feel they are only technicians.. Kon sa standard (ASTM, IS, or BS) follow up kiya hai..??🤔

[@ranbeersinghbuthyal4929]

As per ( ISRM) YIELD STRENGTH 200KN AS PER CLASUE 8.6.4.1

[@hanifullahkhan2993]

​@@ranbeersinghbuthyal4929 Hi sir hope you are well If Rock bolts length and dia is 3m/25mm ,then how much needed working load for that, if rock is very strong

[@kibakibivlogs9318]

Shotcrete assa nehi huwa

[@tojohidekitojo5703]

what job ?🤭🤭🤭🤭🤭🤭🤭🤗🤗🤗🤗🤗

Bato se lg raha ki tum log pahadi ho

[@ranbeersinghbuthyal4929]

Yar pahadi ho ya city wale hai toh insaan hi naa kya tum aisa bol rehe ho
