Problems solved by technology

In addition, the foundations of bridges crossing rivers and seas are mostly located on bad foundations, and their foundation treatment is also a big problem
[0003] At present, most domestic buildings (including bridges) adopt the structure of the superstructure, foundation and foundation to bear the force together. Therefore, relatively indirect overall reinforcement of the superstructure, deep foundation, foundation treatment and other methods are often used to alleviate the uneven settlement. damage, but this mitigation is less effective and there is still a risk of economic loss due to damage

Embodiment

[0071] Such as figure 1 , 2As shown, an adjustment device adapted to uneven settlement of buildings, the device includes an inner cylinder 1, an outer cylinder 2 sleeved outside the inner cylinder 1, a moving column 3 for connecting with the building, multiple liquid outlet mechanisms and multiple A liquid inlet mechanism, the axis of the inner cylinder 1 coincides with the axis of the outer cylinder 2, and an inner cavity 101 filled with a liquid (light liquid) is formed in the inner cylinder 1, and the moving column 3 is vertically movable in the inner cavity 101. In the cavity 101, an outer cavity 213 filled with a No. 1 liquid (light liquid) is formed between the inner cylinder 1 and the outer cylinder 2, and a plurality of inner cylinder outlets connecting the inner cavity 101 and the outer cavity 213 are provided on the inner cylinder 1 along the circumferential direction. The liquid hole 102 and the liquid inlet hole 103 of the inner cylinder. The liquid outlet mechani...

Abstract

The invention relates to an adjusting device suitable for building differential settlement. The device comprises an inner cylinder, an outer cylinder sleeving the inner cylinder, a moving column, a plurality of liquid outlet mechanisms and a plurality of liquid inlet mechanisms, an inner cavity filled with first liquid is formed in the inner cylinder, the moving column is vertically and movably arranged in the inner cavity, an outer cavity filled with first liquid is formed between the inner cylinder and the outer cylinder, a plurality of inner cylinder liquid outlet holes and inner cylinder liquid inlet holes which communicate with the inner cavity and the outer cavity are formed in the inner cylinder in the circumferential direction, and each liquid outlet mechanism comprises a liquid outlet rod which can horizontally move and is used for controlling the inner cylinder liquid outlet holes to be opened and closed. Each liquid inlet mechanism comprises a liquid inlet rod which can movehorizontally and is used for controlling the inner cylinder liquid inlet holes to be opened and closed. Compared with the prior art, additional force caused by differential settlement to an upper structure is released as much as possible while it is guaranteed that the upper structure, a base and a foundation are stressed together.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an adjusting device adapted to uneven settlement of buildings. Background technique [0002] At present, building damage caused by uneven settlement is quite common, especially in areas with poor soil quality in southern China. It is not uncommon for building exterior walls to crack due to uneven settlement caused by insufficient rigidity of the upper part of the building or improper foundation treatment. In addition, the foundations of bridges crossing rivers and seas are mostly located on bad foundations, and their foundation treatment is also a big problem. [0003] At present, most of the domestic buildings (including bridges) adopt the structure of superstructure, foundation and foundation, so they often use relatively indirect overall reinforcement of the superstructure, use of deep foundation, foundation treatment and other methods to alleviate the uneven settlement...
