Problems solved by technology

In view of the fact that the layout of the logistics storage base is a single-story or double-story steel structure factory building, which occupies a large area, the land resources in the Yangtze River Delta region are currently in short supply, and the cost of obtaining land is high. The superstructure can be directly constructed), and the cost of land is relatively high, so now the logistics real estate company usually selects the location of the logistics base in the suburbs or coastal areas with poor soil quality, where there is a certain thickness of soft soil, the project The nature is relatively poor, and it is difficult to directly meet the construction requirements of high-rise buildings in the later site

Embodiment

[0042] Example: such as Figure 1 to Figure 5 As shown, the ground leveling system used for storage floor settlement control in this embodiment is mainly aimed at the situation of a small logistics warehouse area of ​​48×87m, in which the steel structure has a single span of 12m×22m, and the structural pile foundation 6 is distributed Where there are steel columns in the warehouse area, the foundation 13 is in the form of an independent foundation, and the foundation 13 is supported on the structural pile 14 below it. The ground conditions from top to bottom are: 1-2m miscellaneous fill, 15m muddy silty clay 10, clay, silty clay 11, bearing layer 12.

[0043] First of all, due to the technical requirements of the storage and logistics base, the reservoir area needs to be backfilled with a new backfill clay layer 9 of about 1-2m. After the filling is completed, the foundation leveling system in this embodiment can be applied. -Three times of low-energy level dynamic compaction...

Abstract

The invention relates to the technical field of foundation treatment and foundation reinforcement, in particular to a foundation leveling system for controlling settlement of a storage terrace and a construction method thereof. The system is characterized in that the system comprises a plurality of structural pile foundations, a plurality of leveling pile foundations, flexible foundation separation belts and horizontal reinforcement bodies, wherein the structural pile foundations and the leveling pile foundations are uniformly arrayed, the flexible foundation separation belts correspondingly connect the structural pile foundations and the leveling pile foundations one by one and divide a foundation into a plurality of chambers, and the horizontal reinforcement bodies are arranged at the upper part of the flexible foundation separation belt and support a structural layer of the storage terrace. The foundation leveling system for controlling settlement of the storage terrace and the construction method thereof have the advantages that the foundation leveling system is suitable for large-area ground load, especially terrace settlement control of buildings such as factories, workshopsand warehouses, and have the advantages of short construction period, controllable construction quality, low engineering cost, good anti-seismic effect, high bearing capacity, small uneven settlementand the like.

Description

technical field [0001] The invention relates to the technical field of foundation treatment and foundation reinforcement, in particular to a foundation leveling system for storage floor settlement control and a construction method thereof. Background technique [0002] With the advent of the 21st century, the popularity of the Internet, the rapid development of the network information age, the rapid development of e-commerce and logistics and warehousing industries, and the rapid development of e-commerce logistics, the demand for logistics land has also increased sharply. In view of the fact that the layout of the logistics storage base is a single-story or double-story steel structure factory building, which covers a large area, the land resources in the Yangtze River Delta region are currently tight, and the land acquisition cost is high. If you buy mature land (that is, the soil quality is relatively poor The superstructure can be directly constructed), and the cost of l...
