Description

Technical Field

[0001] The utility model relates to a molded enclosure serving also as a basement side wall system. Background Art

[0002] The construction and use of basements are very common. The usual practice is to construct a retaining system to create engineering conditions for supporting the surrounding soil, and then cast the basement structure within the retaining system. The basement structure is usually reinforced concrete. The usual practice is to consider retaining as a temporary soil support system component. In areas with deep excavation depth and poor soil conditions, the retaining cost is high and there is no subsequent condition for continued use. The economic cost is high, the land is large, and the subsequent use value is extremely low.

[0003] Although conventional slope excavation enclosures have low costs, they require a lot of land, and there are fewer and fewer actual use cases in cities where every inch of land is valuable.

[0004] The reverse construction method has gradually emerged in the enclosure construction method. The main feature of the reverse construction method is to use the underground continuous wall as the side wall of the basement structure. However, the ground wall itself is expensive, and there is a lot of material waste in the ground wall below the excavation surface, and the actual economic benefits are poor.

[0005] The retaining system has developed a recyclable retaining wall. However, this type of wall often requires a high cement content to pre-soften the soil. At the same time, because the retaining piles need to be recycled, the combined use of the basement side wall and the retaining body cannot be achieved, and the plane occupies a large area, which is not conducive to the maximum use of the basement space within the red line. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a molded enclosure that also serves as a basement side wall system. The enclosure can be integrated with the basement side wall to improve the land utilization rate within the red line.

[0007] The technical solution adopted by the utility model to solve the above-mentioned problem is: a formed enclosure also serves as a basement side wall system, which is characterized by comprising steel piles and prefabricated wall blocks; the prefabricated wall blocks are movably inserted on the steel piles, and the prefabricated wall blocks are composed of a plurality of blocks, which are sequentially connected together from top to bottom. When the basement is constructed, the steel piles and the prefabricated wall blocks are combined to form an enclosure system; after the basement construction is completed, some of the prefabricated wall blocks are respectively connected to the basement bottom plate, the basement floor plate, and the basement top plate, and all the prefabricated wall blocks constitute the basement side walls.

[0008] The prefabricated wall block of the utility model is provided with a positioning structure, and the positioning structure is inserted into the steel pile.

[0009] The positioning structure described in the utility model is a positioning hole or a positioning groove.

[0010] The prefabricated wall blocks of the utility model are fixed with positioning embedded parts, and two upper and lower adjacent prefabricated wall blocks are connected together through the positioning embedded parts.

[0011] The utility model provides connecting structures on some prefabricated wall blocks. After the basement construction is completed, the prefabricated wall blocks are respectively connected with the basement bottom plate, the basement floor plate and the basement top plate by the connecting structures.

[0012] The connection structure described in the utility model is a connection steel bar.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] The embodiment of the utility model comprises a steel pile 2 and a prefabricated wall block 3 .

[0024] After applying the friction reducing agent, the steel pile 2 is inserted into the pre-installed cement soil continuous wall 1, and the steel pile 2 plays the role of positioning and anchoring. The steel pile 2 is an H-shaped steel column.

[0025] The prefabricated wall block 3 is movably inserted on the steel pile 2, wherein a positioning structure 31 is provided in the prefabricated wall block 3, and the positioning structure 31 is inserted into the steel pile 2 to achieve positioning. The positioning structure 31 is a positioning hole or a positioning groove. The prefabricated wall block 3 is used as the retaining side wall of the foundation pit excavation in the near future, and also as the permanent basement side wall in the later period. The prefabricated wall block 3 is composed of several blocks, which are connected together from top to bottom; wherein, a positioning embedded part 32 is fixed on the prefabricated wall block 3, and two adjacent prefabricated wall blocks 3 are connected together through the positioning embedded part 32. When constructing the basement, the steel pile 2 and the prefabricated wall block 3 are combined to form a containment system.

The steel pile 2 is used as an advance anchor in the soil layer of the retaining wall during the subsequent foundation pit excavation, and is also a pre-positioning component for the subsequent driving of the prefabricated wall block 3.

[0030] Step 3: See Figure 4 , prefabricated wall blocks 3 are driven into the steel piles 2 of the softened soil that has not yet hardened.

[0031] Step 4: See Figure 5 When constructing the basement, the retaining wall formed by the steel piles 2 and the prefabricated wall blocks 3 is used to form a retaining system.
