Description
Technical field
The present invention relates to base pit engineering technical fields, pull out synchronous device for filling more particularly to a kind of SMW engineering method stake.
Background technique
Stiffened soil-cement stirring wall engineering method (abbreviation SMW engineering method) is to utilize multiaxis deep mixer (TRD/CSM equipment) just
Ground drilling cutting, while cement grout is injected, it is stirred after being sufficiently mixed repeatedly, then the core materials such as H profile steel or steel sheet pile are inserted into
In churned pile wall, being formed can earth-retaining but also the compound diaphram wall body that blocks water.SMW engineering method has the characteristics that low cost,
It is primarily due to fashioned iron and pulls out carry out recycling and reusing.Generally take yellow ground backfill closely knit or pressure in the gap that fashioned iron leaves after pulling out
Close slip casting, but rub or tilted pull out or Support Deformation etc. due to, Soil-cement Wall is during fashioned iron rises and pulls out
Will appear part cracking destruction, this will lead to gap and can be blocked in vertical height, rather than be connected to, at this time to gap into
It when row filling, will be unable to fill closely knit, and then left a void under at blocking, this will lead to long period inner periphery after construction
The continuous deformation of building.
It is found through being retrieved to prior art document, grant number is that the patent document of CN101929343B discloses " SMW engineering method
Profile steel pulling and grouting ", proposition are boring injected hole wait pull out beside fashioned iron, when then promoting fashioned iron through injected hole into gap
The method of slip casting, this method can effectively solve the problem of gap is blocked, and can prevent from gushing on underground water, but it is relatively difficult to guarantee
