Demolition Techniques

Demolition Techniques

You may assume demolition is simply blowing things up. Some involve explosions but it is however way more technical than that. There are various demolition techniques that are considered as ‘demolition’.

 

It must be noted that before any demolition takes place the following practices need to be completed according to The Constructor

1. Surveying
2. Removal of hazardous materials
3. Preparation of plan
4. Safety measures

 

Taking the above into account the following (according to Civil Engineering News) are selected.

1. Non Engineering Demolition also known as Manual.

a) Refering to tools such as Sledge Hammers, Jack Hammers and Drillers which are used by workers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Engineering Demolition which is split into 3 categories.

a) Mechanical Method:

Wrecking Ball (think Miley Cyrus but without the theatrics)

Pusher Arm technique (a specialised hydraulic arm used for smaller buildings)

Thermic Lance Technique (using flaming temperatures of 2500 ⁰C to melt reinforcement)

Non-Explosive (drilling and filling with expanding slurry)

Concrete Sawing

Deliberate Collapse (significant structural items are removed)

Pressure Jetting (thanks to H²0)

 

b) Implosion: Inward disintegration using explosives

c) Deconstruction: Non-structural and structural

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Demolition encompasses many techniques and is often used in conjunction with new construction or renovation.

In conclusion, I’ll take inspiration from Rumi, ‘In this life many demolitions are actually renovations.’
