Further, the augmentor 5 is jack.
A kind of construction method of above-mentioned displacement servo formula combined enclosure structure, comprising the following steps:
S1, positioning displacement control system: preparation grooving region 2, and grooving region 2 is made to become stream modeling shape；S2, lifting boxlike
Rigid box 4, and be inserted perpendicularly into grooving region 2；S3 is positioned and building enclosure 8 of constructing, and installs system for monitoring displacement 7；S4,
Soil stabilization and excavation after being cheated；It is real based on the monitoring data of system for monitoring displacement 7 in Excavation Process
When regulate and control the thrust magnitude of augmentor so that the displacement real-time recovery of boxlike rigid box 4 caused by excavating.
Further, in step S1, the boxlike rigid box is at least positioned to excavation pit by protection structure one
Side.
The utility model has the beneficial effects that:
1) it is realized in the form of area load and land movement behind hole is directly controlled, control effect is more excellent；
2) boxlike rigid box can be prefabricated, and prefabricated construction improves the efficiency of construction on the outside of foundation pit；
3) due to the presence of boxlike rigid box, in augmentor arrangement can be more than foundation pit depth, can be with
Bit andits control is carried out to the lower soil body is cheated, it is of great advantage to the Deformation control of deep foundation building；
4) displacement control system is precast construction, and is constructed before building enclosure and excavation of foundation pit, native land body digging process
In, land movement can be adjusted in time, and the time difference is not present in soil excavation and augmentor clipping room, and Bit andits control is not present
Any lag strengthens the protection to deformation sensitive building；Therefore, the deformation-compensated stagnant of existing deformation-controlling measures is compensated for
The deficiency of property and Support Position limitation afterwards.
