Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a soil retaining and enclosure structure. Background Art

[0002] The foundation pit project is to excavate an underground space from the ground downwards. Vertical retaining structures are generally set up around the deep foundation pit. The retaining structure includes pile rows and support structures. The pile rows are inserted into the base of the excavation surface, and the support structure supports the pile rows, thereby reducing the deformation of the retaining structure and controlling the bending moment of the wall. The support structure is divided into two types: internal support and external anchor.

[0003] Internal supports usually take the form of steel supports and reinforced concrete supports. However, they have problems such as long construction period, difficulty in installation and removal, and great impact on underground structure construction. External anchors usually use anchor cables and anchor rods, but due to their long design length, they often exceed the land red line, affecting the safety of surrounding buildings, roads, pipelines or the construction of adjacent plots. Therefore, a suitable support form is urgently needed to solve the above problems. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is that both the internal support and the external anchor in the prior art have certain technical problems during the construction process, thereby providing a retaining enclosure structure.

The anchor piles are arranged opposite to the row of piles and are fixedly connected to the opposite row of piles via a connecting beam.

[0008] Furthermore, a drainage pipe is arranged in the arch wall, the water inlet end of the drainage pipe is arranged in the soil layer between the row of piles and the anchor piles, and the water outlet end of the drainage pipe extends to the outside of the arch wall toward the side of the arch wall away from the anchor piles.

[0009] Furthermore, the ends of adjacent rows of piles away from the ground are connected to each other through a cap beam.

[0010] Furthermore, it also includes:

[0030] Specifically, a plurality of rows of piles 1 are evenly spaced along the periphery of the foundation pit, one end of the row of piles 1 is inserted into the soil layer 8, the row of piles 1 is perpendicular to the ground, adjacent rows of piles 1 are parallel to each other, an arch wall 2 is built between adjacent rows of piles 1, the arch wall 2 connects adjacent rows of piles 1, and the row of piles 1 and the arch wall 2 form a fence, a plurality of anchor piles 3 are arranged on the soil facing side of the row of piles 1, the side of the row of piles 1 facing the soil layer 8 is the soil facing side, the anchor piles 3 are spaced apart from the row of piles 1, the anchor piles 3 are inserted into the soil layer 8 as a whole, and the anchor piles 3 are arranged opposite to the row of piles 1. In this embodiment, any one of two adjacent rows of piles 1 is arranged opposite to the anchor pile 3, and the spacing between adjacent anchor piles 3 is the same. The upper end of the anchor pile 3 is fixedly connected to the row of piles 1 opposite to it through a connecting beam 4, thereby playing a role in supporting the row of piles 1.

[0031] Further, such as Figure 2 As shown, the ends of adjacent rows of piles 1 away from the ground are connected to each other through a cap beam 6. The upper ends of adjacent rows of piles 1 are connected to each other through the cap beam 6, one end of the connecting beam 4 is fixedly connected to the upper end of the anchor pile 3, and one end of the connecting beam 4 is fixedly connected to the cap beam 6.

[0032] Furthermore, a drainage pipe 5 is provided in the arch wall 2, and the water inlet end of the drainage pipe 5 is provided in the soil layer 8 between the row of piles 1 and the anchor piles 3, and the water outlet end of the drainage pipe 5 extends to the outside of the arch wall 2 toward the side of the arch wall 2 away from the anchor piles 3.

[0033] Specifically, Figure 1 As shown, the left end of the drain pipe 5 is the water inlet end, and the water inlet end of the drain pipe 5 is arranged in the soil layer 8 between the pile row 1 and the anchor pile 3. The right end of the drain pipe 5 is the water outlet end, and the water outlet end of the drain pipe 5 extends toward the foundation pit and extends out of the arch wall 2. The drain pipe 5 can discharge the water in the soil layer 8, thereby reducing the pressure of the soil layer 8 on the arch wall 2 and the pile row 1.

[0035] Specifically, Figure 1 As shown, on the ground above the slope support 7 connecting beam 4, there is a soil layer 8 between the slope support 7 and the connecting beam 4. The slope support 7 can protect the soil layer 8 from being washed away by rainwater and caused to be lost. The right end of the slope support 7 has a bending portion 9 bent toward the direction of the connecting beam 4, and the bending portion 9 is in contact with the upper side surface of the right end of the connecting beam 4.

[0036] Further, such as Figure 1 As shown, a water retaining ridge 10 is arranged on the side of the slope support 7 away from the connecting beam 4.

Preferably, in this embodiment, the filtering structure is gravel, which is arranged at the water inlet end of the drain pipe 5. The gravel can block the mud in the soil layer 8 and prevent the mud from flowing into the drain pipe 5 along with the water.

[0039] Further, such as Figure 1 As shown, it also includes: a drainage ditch 12. The drainage ditch 12 is arranged in the foundation pit and is located below the water outlet end of the drainage pipe 5. The drainage ditch 12 can collect water discharged from the water outlet end of the drainage pipe 5, and can also collect water in the foundation pit. The drainage ditch 12 is connected to a water pump so that the water in the drainage ditch 12 can be discharged.
