The invention provides a construction method for preventing an underground
pipe gallery from generating differential settlement, and belongs to the technical field of
building construction. The methodcomprises the following steps that a foundation is treated, a
cushion layer is laid, a template is erected, steel bars are laid, concrete pouring is carried out, a settlement correcting
system is installed, and grouting correction is carried out. According to the construction method for preventing the underground
pipe gallery from generating differential settlement, when the data collected by a monitoring device reaches a preset critical value, a control device corrects the device to apply corresponding jacking force or tightening force to the port of the underground
pipe gallery at the two sides of a connecting part so as to compensate the stress difference between two adjacent pipe sections according to the data collected; grouting is carried out at the weak part of the foundation in adrilling mode when the
system has early warning so that the
bearing capacity of the weak part of the foundation can be enhanced, and the pipe gallery can be uniformly settled; the construction methodeffectively restrains differential settlement at the connecting part of the pipe gallery, a lot of later maintenance cost is reduced, and the occurrence of vicious events caused by pipe gallery differential settlement is avoided.
