Embodiment Construction

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042]It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations ...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a construction method for preventing differential settlement of an underground utility gallery. Background technique [0002] At present, the construction of comprehensive underground pipe corridors in major cities across the country has been carried out one after another, but due to the immature technology, a series of problems have emerged in the construction of the project, among which the consequences of subsidence and misplacement are the most serious. [0003] Settlement staggering is due to differences in foundation treatment or changes in geological conditions during engineering construction, resulting in differences in foundation bearing capacity between adjacent pipe sections, and differences in foundation bearing capacity will lead to height differences at the joints of adjacent pipe sections When this difference in height reaches the allo...
