👉 የአፈርን የመሸከም አቅም (BEARING CAPACITY) እንዴት እንጨምር??...
.
* ሶስት አይነት የአፈርን የመሸከም አቅም ማስተካከያ ቴክኒኮች አሉ - mechanical, chemical & other stabilization techniques
.
A) ሜካኒካል ውስጥ :-
.
1. Compaction - አፈሩን ስንጠቀጥቀው density/ unit
weight ይጨምራል ያ ማለት ደግሞ አፈርን የመሸከም አቅም ጨመረ ማለት ነው::
.
2. Excavation and Replacement – expansive soil ከሆነ ወይም ሌላ አስቸጋሪ አፈር ከሆነ ይህን መጠቀም እንችላለን
.
3. Mixing of Different Soils - ሳይታችን ላይ ያለው አፈር
coarse ወይም fine ብቻ ከሆነ ወይም ደግሞ አፈሩ አንድ አይነት
ብቻ ፀባይ ካለው ከተለያዩ አፈሮች ጋር በመደባለቅ የተሻለ የአፈር
ፀባይ ማግኘት እንችላለን
.
B) ኬሚካል :-
.
1. Lime stabilization - ይህንን የምንጠቀመው በአብዛኛው
ለexpansive soil ነው፡፡ አፈሩን ከ Lime ጋር በመደባለቅ
plasticity መቀነስ እንችላለን፡፡ የlime መጠኑ ከሚያስፈልገው
በላይ ከበዛ ግን B.C. ይቀንሳል፡፡
.
2. Cement stabilization - ሲሚንቶን ከአፈር ጋር በመደባለቅ
የተሻለ ውጤትን የምናገኝበት መንገድ ነው፡፡ concrete
pavement ስር መጠቀም እንችላለን በአብዛኛው ለአየር
መንገዶች ፤ ለአውራ ጎዳናዎች ፤ ግድቦችን ከሽርሸራ ለመከላከል
ወ.ዘ.ተ. መጠቀም እንችላለን፡፡
.
3. Asphalt stabilization - አስፓልትን ከአፈር ጋር በመደባለቅ
የተሻለ ውጤትን የምናገኝበት ዘዴ ነው በተለይም ለcohesive
አፈሮች፡፡ አፈሩን water proof በማድረግና ውሃማነትን በመቀነስ
B. Cን መጨመር እንችላለን፡፡ በአብዛኛው ይህንን ድብልቅ
ለመንገዶች እንደ base course መጠቀም እንችላለን፡፡
.
.
C) ሌሎች የአፈርን ባህሪ ማስተካከያ መንገዶች:-
.
1. Drainage - ፓይፖችን አፈር ውስጥ በመቅበር ወይም
ጉድጓዶችን በመጠቀም ground water የምንቆጣጠርበት ነው
.
2. Precompression - ግንባታ ከመጀመራችን በፊት አፈሩ ላይ
ሎድ በመጫን ኮምፓክት የምናደርግበት ዘዴ ነው

3. Dynamic Stabilization
.
ሀ) Blasting - ቦምብ ወደውስጥ በመቅበር በፍንዳታው አፈሩ ይጠቀጠቃል::
.
ለ) Compaction Piles - ፓይሎችን ወደውስጥ በማስገባት
አፈሩ ወደ ጎን እንዲሸሽና እንዲጠቀጠቅ ማድረግ ይቻላል፡፡
ፓይሉን ስናስወጣውም በተቦረቦረው ጉድጓድ ውስጥ የተሻለ አፈር በማስገባት የአፈርን የመሸከም አቅም ማስተካከል እንችላለን፡፡
.
4. Injection And Grouting - አፈሩን በሲሚንቶ ወይም
በተለያዩ chemical ውህዶች በpressure በመምታት ground
water ና settlement መቆጣጠር እንችላለን፡፡
.
የተሻለውን ዘዴ ለመምረጥ የአፈሩንና የአካባቢውን ሁኔታ ፤
ኢኮኖሚ ፤ ሴፍቲና የመሳሰሉትን ነገሮች ማጤን አለብን፡፡

✅Do you know that the homogeneity of a concrete mixture
contributes immensely to its strength and workability.
However, concrete is expected to fall from a height of not
more than1.2m. Therefore proper attention should be given to
concrete during batching, mixing, transporting and placement
inorder to maintain a homogeneous mixture.

💚Methode of curing concrete

:- Spraying
:- wet covering of surface
:- Ponding
:- Applecation of curing chemicals
:- steam curing

#10 Points engineers should remember on site:

1: Check size of bars for slab beam and column etc.
2: Length of bar for any steel which we use for construction works.
3: Position of bars.
4: Count No’s of steel bars.
5: Check lap length of steel.
6: Check concrete cover for steel reinforcement.
7: Spacing of bar for beam column and slab etc.
8: Direction of bars.
9: Check over all dimension of beam and slab.
10: Check beam and slab lever before starting concrete work.

Road Construction
Very broadly, the construction of roads can be described by three processes:
👉Setting out.
👉Earthworks.
👉Paving construction.

Methods of Setting Out Survey
1. Setting out buildings by coordinates
2.Setting out with theodolite and level
3. Checking verticality
4. Setting out and alignment in steel framed buildings
5. Alignment and verticality in form work
6. Control and calculation for route surveying

This handy book presents more than 2000 needed formulas for civil engineers to help them in the design office, in the field, and on a variety of construction jobs, anywhere in the world. These formulas are also useful to design drafters, structural engineers, bridge engineers, foundation builders, field engineers, professionals engineer license examination candidates, concrete specialists, timber-structure builders and students in a variety of civil engineering pursuits.

👉Coffer_Dam
A cofferdam, also called a coffer, is an enclosure built within, or in pairs across, a body of water to allow the enclosed area to be pumped out. This pumping creates a dry working environment so that the work can be carried out safely.
