Problems solved by technology

Summarizing the current existing rectification construction methods, it can be divided into forced landing rectification and jacking rectification. Among them, forced landing rectification requires sufficient construction site on the side with small settlement. After the rectification is completed, the building will sink as a whole, which often affects its use. function, and in the process of deviation correction, there is a large dragging settlement to the surrounding buildings (structures); and the jacking method, due to the long preparation time for deviation correction, the stress concentration during the deviation correction construction, the control of the deviation correction process is difficult, and the risk is high. Due to high cost and other reasons, it is greatly restricted

Embodiment Construction

[0017] As the directional expansion correction method of the present invention such as figure 1 and figure 2 An embodiment shown mainly introduces the construction process and steps of this deviation correction method. exist figure 1 In the first stage shown, at first, according to the verticality observation data, it is determined that the inclined building (2) is inclined in the opposite direction to the adjacent building (1), and the first stage of this embodiment of the directional swelling correction method is completed, that is, the building is determined Then enter the second stage of this embodiment of the directional expansion and rectification method. After investigation, the inclined building (2) adopts natural foundation, and it is necessary to correct the deviation of the inclined building (2). Due to the existence of the adjacent building (1) and its closeness to the inclined building (2), the deviation correction process There is no construction operation su...

Abstract

The invention relates to a construction method for directional expansion-rise deviation rectification in the field of deviation rectification of civil engineering buildings (structures), which comprises the following steps: a) determining the inclined direction of a building (structure) (2); b) according to the inclined situation of the building (structure) (2), determining the position of a deviation rectification construction required rise-promoting part (3); c) determining a rise-promoting height required by the deviation rectification construction required rise-promoting part (3); d) constructing an expansion-rise counter-force foundation at the required rise-promoting part (3), and arranging an expansion-rise construction space between the expansion-rise counter-force foundation and an original building (structure) foundation; e) arranging an expanding agent (7) in the expansion-rise construction space; f) lifting an original building (structure) at the rise-promoting part (3) through the expanding agent (7); and g) according to the needs of the rise-promoting height, determining whether to repeat the step e) and the step f) until deviation rectification requirements are satisfied. The construction method solves the problems that a rise-promoting method for the inclined building (structure) (2) is concentrated in deviation rectification stress, difficult in construction control and large in construction risk; and the construction method is rapid in deviation rectification construction speed, safe, reliable, and low cost, and has small influences on the surrounding environment.

Description

technical field [0001] The invention relates to the field of deviation correction of buildings (structures) in civil engineering. Background technique [0002] With the rapid development of underground space development and urban construction, due to various reasons such as soft soil foundation, excavation of adjacent foundation pits, excavation of surrounding tunnels, and large area of ​​nearby piles, etc. ) The settlement and uneven settlement of the building (structure) are large, resulting in the tilt of the building (structure), which affects the normal use and safety of the building (structure). Corrective processing. At present, the commonly used deviation correction methods include soil excavation correction method, rotary grouting pile correction method, water immersion correction method, jacking correction method, stress relief correction method, grouting correction method and other building (structure) deviation correction construction methods, and have been in t...
