DEWATERING

 What is dewatering and why dewatering is important? You never know that. But if you are an experience enough you are cleared with this term. But if you are studying in college and not visited any site then you may never know this. But by the way if you are a farmer's son then you might have used this machine. 

Dewatering is necessary if the foundation pit is full of water and no PCC or sand filling can be provided. If the water is present it will lead to the accommodation of water. No work will be done properly and there will be lot of tension. So to empty the water mechanical water pump is used for dewatering. So that the excavation pit remains empty with water and the work can be done easily. 




As the water is poured inside the pump it opens up through the valve. But be careful no air should remain inside or trapped into the machine. Otherwise the machine will give problem. After pouring all the water in the pump, the mouth is kept hold for few seconds of the machine so that no air enters in it. And it is hold until the machine gives starts. The mechanical turbine is rotated with the help of a handle and it gives a blowout pressure as the water comes out. The main thing of using this water pump is to clear out the excavation water.

Moreover in some foundations water remains, but it will longer time to clear out the water. So by keeping little amount of water on the base of the excavation the brick soiling and PCC work is done. But that's not good. Then also what to do because after clearing out the ground water then also it remains same after 1 to 2 hours. Because the water level rises up and up.

It is the most common and widely used machine in any construction project whether its big or small project. It becomes easier and makes the work faster for the companies at any time of interval.    All other machines such as Transit Mixer, Concrete Mixer, Roller etc are also used in any kind of road project or building project. Transit Mixer is used for large large building projects, bridge projects, some kind of road projects etc. whereas concrete mixer is for small building projects. Roller is used for road project and bridge project for its elevation.  For any building project the most commonly used machines are concrete mixer, transit mixer, concrete pump, bar bending machine, needle vibrator, water pump and many more. All these machinery works make the work easier and faster. Otherwise if the work is done with labourers it will take more time and less efficient ...

How to edit grid systems in Etabs

 Okk in the last blog I had discussed about Etabs for beginners. You have got at least some ideas about it. If you have not seen it then click here . But here I am going to discuss how you will edit Grids/Columns in Etabs. As I had said by clicking on "Modify/Show Grid Systems" option a new dialog box appears, their you can edit anything. But you can also do it by different way. On the left side in grid dimensions (plan) you can see that two options are available. One is "Uniform Grid Spacing" and the other is "Custom Grid Spacing". Click on the "Custom Grid Spacing" and you see that Edit Grid Data option is available. Just click on that, and you can edit it as you want by giving the required dimensions in X-axis and Y-axis only. Ok whatever be lets come to the topic. If you have done it like as I have shown earlier then follow those steps. And the one who were new to this blog this is just for that. That's why I underlined with BLUE line an...

How to make 3D Render in Etabs

 Ok, so in the last two blogs I had described about how to make  beams, columns, slabs  and  staircase  in Etabs. But as a beginner for somebody it's easy whereas for someone it's rough to understand or have misconception. If you have not understood or read it then go to the above links and practice it again. And if you have understood then it's good and go forward for the upcoming steps. Because the more you learn, the more you understand. The more you get knowledge, the more you learn new things. So if you want to render like as if I had rendered it then you are on the right website. Just follow the instructions as I have told you.  This is the Rendering view, which I have Rendered. You can also see the 3D View also. After making the complete building structure and modelling all those beams, columns, slabs, staircase etc. you come to the ribbon wizard which is above plan view or 3-D view. You can see a Tick-mark ☑ option which is also known as "Set Displa...
