What is the function of a Waler?

What is the function of a Waler?

Walings are designed to transmit all loads from the soil through the retaining wall to the steel tie bars and to align and brace the wall in its position. In many applications, a steel waler or reinforced concrete beam is used to transfer retained loads evenly between tie rod connection points.

What does Waler mean?

: a horse from New South Wales especially : a rather large rugged saddle horse of mixed ancestry formerly exported in quantity from Australia to British India for military use.

What is a strut beam?

The part of the structure that has a tensile force acting on it is called a TIE and the part that has a compressive force acting on it is called a STRUT. WALL. The beam is held in position by a steel rod. The weight of the beam is stretching the rod (tensile force).

What is the purpose of a strut?

They are mounted at the top of the chassis at the front-end of most front-wheel-drive vehicles. However, struts are not limited to front-wheel-drive configurations. The primary purpose of the struts is to support the weight of the vehicle while also absorbing surface impacts and ensuring a smooth ride.

What do you mean by strut?

Strut implies swelling pride or pompousness; to strut is to walk with a stiff, pompous, seemingly affected or self-conscious gait: A turkey struts about the barnyard. Swagger implies a domineering, sometimes jaunty, superiority or challenge, and a self-important manner: to swagger down the street.

How do you calculate struts?

To calculate the size and the force of the Gas Strut you require for your application use the following guidelines. The extended length of the Gas Strut should be approximately 60% of the door or hatch length - e.g. a 1000mm high door should have a Gas Strut length of approximately 600mm.

How does a gas strut work?

Camloc gas struts work by forcing, under pressure, an inert gas (Nitrogen) into a cylinder. The internal pressure then greatly exceeds atmospheric pressure. ... On extension or compression, gas is transferred from one side of the piston to the other via a small orifice.

How are gas strut positions determined?

In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm long gas strut would be about right. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.

What does 100N mean?

You will often see 50N on buoyancy aids and 100N or 150N on life jackets. This indicates how buoyant they are. The 'N' stands for Newton, and this is known as the 'Newton Range'. Buoyancy Aid.

What buoyancy aid do I need?

For an adult of say 70kg, a buoyancy aid should give at least 50 Newton's buoyancy, while lifejackets of 100N and 150N should give the respective buoyancy. Lifejackets should be constructed in such a way so as to turn an unconscious person into an upright position and keep his/her airways clear of water.

How long does a buoyancy aid last?

three years

How do you test for buoyancy aid?

A simple test for a lifejacket or buoyancy aid is to hang on an appropriate weight, squeeze out all the air and see if it floats. If it does float it is OK.

How does a buoyancy aid work?

Buoyancy aids are simply that - an aid to buoyancy that generally relies on help being close at hand. It assumes that the wearer is able to help themselves to some degree by swimming to safety or by keeping themselves afloat while assistance arrives if required.

What does buoyancy aid mean?

personal flotation device

How do you use a personal flotation device?

PFD Specifications

  1. Put your PFD on and enter water deep enough that you can float without touching the bottom.
  2. Tilt your head back and relax your body.
  3. Your chin should be above water and your breathing should be easy. If your mouth is not above the water, you need a PFD with more buoyancy.
