[0002] When building a house, in order to ensure the quality and stability of the house, it is necessary to excavate the foundation pit during the foundation construction. Since house construction is usually carried out in urban areas, there are generally other buildings around the construction area. In order to ensure that the construction project will not affect the existing project, the foundation pit needs to be reinforced and maintained to ensure that the soil foundation at the edge of the foundation pit does not slip, avoid affecting the surrounding buildings, and ensure the smooth construction of the foundation. At present, the foundation pit maintenance fence usually uses trapezoidal bent plates as baffles. The support range of the single structure is small. In order to meet the support and maintenance needs, a large number of baffle units need to be connected. The construction volume is extremely large. At the same time, when constructing a deep foundation pit, the foundation pit wall needs to be supported by purlins. At present, when installing purlins, it is often used to weld support beams on the back of the baffles and then connect and fix the purlins to the support beams. The construction efficiency is low and the construction is inconvenient. Utility Model Content

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] The ribs 11 are fixedly mounted on the sides of the frame 1 for connection and fixing, and a pin hole 12 is provided on each rib 11 along the longitudinal direction. The connecting beam 2 is connected and arranged between two adjacent frame 1s. A plurality of connecting fins 21 are provided at the upper edge of the front end surface where the connecting beam 2 is connected to the frame 1 for connection, and each connecting fin 21 is respectively positioned at the groove position on the back side of each frame 1. A second pin hole 22 is provided on each connecting fin 21. The connecting fin 21 is inserted into the groove on the back side of the frame 1 and is placed on the rib 11. The second pin hole 22 is aligned with the first pin hole 12, and the plug pin 4 is inserted into the second pin hole 22 and the first pin hole 12, thereby completing the detachable fixed installation of the connecting beam 2 on the frame 1.

[0016] The positions of two adjacent enclosure panels 1 are as flat as the rest of the positions. The enclosure panels 1 change the structural form of the traditional single trapezoidal bent panels and adopt an integral corrugated structure with strong integrity, convenient loading and unloading, and high construction efficiency.

[0017] The housing construction foundation pit maintenance device also includes a pressure block 3 and a plurality of bolts 5. The pressure block 3 is configured to imitate the groove on the back of the enclosure plate 1.
