Steel structure small bridge construction plan, can you give a sample to the younger brother? Thank

Female Joy, No. 52, with a 2888 gold card.

86 Emei! There is a martial saint card! 75 Wudang has a VIP card!

A desktop computer of about 3000 is better, hehe. Look at what card、That part is good.。。 Just buy that part, don't ask for a brand! Assemble at the end!

The choice of foundation pit support depends on the excavation depth of the foundation pit, the physical and mechanical properties of the foundation soil, the hydrological conditions, the surrounding environment (such as the importance of adjacent buildings and structures, the degree of restriction of adjacent roads and underground pipelines, etc.), the design control deformation requirements, the capacity of construction equipment, the construction period, the cost and the stress characteristics of the supporting structure.

According to the geological conditions, choose different forms of foundation pit support, or a combination of several forms.

The selection of foundation pit support scheme should be based on local conditions, comprehensive technical, economic, safety and environmental factors, so that the measures are appropriate, safe and reasonable, and harmless to the environment.

The basic basis for the selection of foundation pit support scheme:

1. The plane size of the foundation pit and the depth of excavation;

2. Engineering geology and hydrological conditions;

3. Load situation (earth pressure, water pressure, load distribution, construction load, building load) 4. Environmental conditions.

Although the production practice life at the construction site can reflect the construction management and organization of several positions such as safety administrators in the building decoration construction project, the engineering department according to the scale and difficulty of the project.

If you write like this, even if you translate it, it won't work.

First of all, if you decide not to disturb other people's families, then don't be so inky and just say, goodbye, I'm going back to China! (Take out some manhood).

It's impossible, it doesn't have to be so complicated, it hurts others and hurts yourself, good women are in China, so don't get entangled!

Bang, it's only 30 points. Hang more than 100. Or no one cares.

Don't be greedy for the cheapness of Tietong.

People's signal is not as good as telecom Netcom, and it is okay to go to the web page to play the game.

I'm dizzy, this buddy, you don't know, the key is not in the computer but in your broadband, the line of fire is only telecommunications and Netcom, and of course you use Tietong 100 megabytes, unless you use telecom and Netcom, any other way will not work.
