Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and in particular relates to a ground subsidence reinforcement monomer and a multi-point horizontal and vertical repair and reinforcement system composed of the monomer and the monomer. Background Art

[0002] The settlement of a building is closely related to its foundation. The foundation conditions are inseparable from the geological conditions, and the geological conditions in different regions are different. In the same site, the geology under each building may also be different. The difference in geology will lead to differences in mechanical properties, which will lead to differences in settlement. Secondly, settlement is related to the foundation. The layout, type, and stiffness of the foundation will affect the settlement. Finally, settlement is related to the superstructure of the building. The stiffness, system, and form of the superstructure will affect the settlement. In addition, the surrounding environment (such as roads, indoor and outdoor facilities, etc.) and new buildings will also affect the settlement of the original building. Especially around old communities over the years, ground settlement is common. Once the ground settlement forms a certain scale and causes obvious damage, it is extremely difficult to control and restore it. It is difficult to restore the already sunken ground to its original appearance. It can only slow down the ground settlement rate or stop the trend of continued sinking to reduce losses. The existing repair methods have the following disadvantages:

[0003] 1. Due to the different locations of settlement, there is a lack of a unified and standardized repair method based on the specific locations of settlement.

[0004] 2. Pour again at the settled area. After pouring, it can achieve a short period of flatness. Later, the new pouring will separate from the original ground, resulting in hollowing phenomenon.

[0005] 3. Filling the bottom of the settlement area can push up the settled ground. However, settlement problems will occur later, resulting in the repair quality failing to meet the expected requirements. Utility Model Content
