Technical Field

[0001] The utility model relates to the technical field of soil retaining technology, in particular to a novel deep soil retaining device. Background Art

[0002] As we all know, soil refers to a loose layer of material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc. It can grow plants. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant, microbial residues, soil organisms, as well as water, air and oxidized humus. Solid matter includes soil minerals, organic matter and nutrients obtained by microorganisms after light inhibition and sterilization. For buildings, soil is used as the foundation for construction. Due to soil quality problems, there will be hard soil and soft soil. Sometimes the soil will be damp, which will weaken the bearing capacity of the soil. Similar to landslides, it is necessary to reinforce the soil foundation. The existing reinforcement method is cumbersome to operate. Wooden boards are used to splice and block soil landslides. There are gaps between the spliced ​​wooden boards, which are prone to soil leakage, affecting subsequent construction. In addition, the strength of the spliced ​​wooden boards is not high, and they will be cut or collapsed over time.

[0003] Therefore, in response to the above problems, research and development and design of soil retaining technology are carried out. Utility Model Content

Among them, the retaining device has:

[0022] (1) Strong rigidity: The vertical piles and the diagonal support piles are connected as a whole, which can enhance the structural rigidity and control the amount of soil movement caused by excavation.

[0023] (2) High reliability: All oblique support piles are embedded in the soil and are independent of each other. Even if a single support pile fails, progressive collapse will not occur.

[0024] (3) Compact structure: The inclined support piles do not occupy a large amount of internal space in the foundation pit, which means that enough space can be left for the use of large machinery and equipment;

[0025] (4) High efficiency and low cost: The steel inclined support piles can pass through the building walls or foundation slabs, with limited impact on the internal structural performance. After the internal structure construction is completed, there is no need to remove part or all of the inclined support piles, which effectively shortens the construction period and reduces the demolition costs.
