SMW construction method, also known as steel-cement soil mixing wall, is used to drill and dig into a certain depth soil layer in the engineering site with a multi-axis type drilling and digging mixer. At the same time, cement slurry is spewed out at the drill bit and the foundation soil is repeatedly stirred, forming a continuous and complete underground wall with certain strength and stiffness, and no joints. A retaining wall, water stop curtain or soft foundation soil reinforcement used for building foundation pit support.
Strong foundation has obtained dozens of innovative technologies in pile foundation engineering, foundation pit engineering, water foundation treatment, land foundation treatment, and has been authorized invention patents54Item, Utility model patent82Item, Appearance design7To promote industrial technological progress as the way of enterprise survival, more than 20 years, in each different period, with continuous innovation results to support the development of enterprises.
Process principle
SMWThe construction method, also known as the section steel-soil-cement mixing wall, is to drill and dig into the soil layer at a certain depth in the engineering site with a multi-axis type drilling and digging mixer, and at the same time, the cement slurry is spewed out at the drill bit and the foundation soil is repeatedly stirred, forming a continuous, complete and non-joint underground wall with a certain strength and stiffness. Used as a buildingFoundation pit supportingThe retaining wall, water stop curtain or weak foundation soil reinforcement.
Advantages of process:
(1) strong seepage and water stop, its permeability coefficientK Can be up to10cm/s;
(2(continuous integrity between piles, no joint;
(3) The ability to stir into the wall is strong, the maximum depth of the wall can be reached65 Meters, into the wall thickness650-1000mm;
(4) to improve ergonomics3-4Times, reduce the construction cost up to50%, shorten the construction period.
