Quality level all has been significantly improved, this haves laid a good foundation for the architectural engineering construction in China.It is built in large-scale
It builds in object, foundation pit support construction technology would generally be applied to.
Pattern foundation pit supporting structure is the safety to guarantee Underground Construction and foundation pit surrounding environment, to foundation pit side-wall and surrounding enviroment
Supporting and retaining system, reinforcing and the safeguard measure of use.The purpose of pattern foundation pit supporting structure and effect 1. guarantee the stability of the soil body of foundation pit surrounding, together
When meet the requirement that basement construction has sufficient space, this is the necessary condition of earth excavation and basement construction.2. guaranteeing base
It is without damage during pattern foundation pit supporting structure and basement construction to cheat the facilities such as surrounding adjacent buildings and underground utilities, i.e. the crater wall soil body
Deformation, the vertically and horizontally displacement including ground and the underground soil body will control within the allowable range.3. by intercept water, precipitation,
The measures such as draining guarantee Foundation Pit Construction work surface more than level of ground water.At present during architectural engineering foundation construction,
Foundation pit support construction technology is more and more widely used, especially during modern urban construction so that foundation pit branch
Shield construction technology is widely used in underground structrue engineering, and in Base hole supporting technology specific implementation process, building is set
What meter staff paid close attention to it the most is exactly the size of its reliability and security.
Summary of the invention
The present invention provides a kind of method of architectural engineering pit supporting that reliability and security is high.
Its technical solution is：
A kind of method of architectural engineering pit supporting, includes the following steps：
Step 1 digs depth, foundation pit flat shape size, sitework geological conditions, ambient enviroment, close to buildings according to foundation pit
Status, determine the scheme of pattern foundation pit supporting structure；
