Description

Technical Field

[0001] The present application relates to the technical field of foundation pit surface protection, and in particular to a foundation pit surface water-blocking enclosure structure. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. The foundation pit is a temporary project. Its function is to provide a space so that the foundation masonry work can be carried out at the location specified in the design. The foundation pit excavation volume is calculated according to the foundation pit volume.

However, the function of the fence is relatively single and cannot block surface water, which causes a large amount of water entering the foundation pit. For this reason, it is necessary to provide a foundation pit surface water-blocking enclosure structure. On the basis of a protective fence, a diversion structure and a water-blocking structure are added to avoid the phenomenon of a large amount of surface water entering the foundation pit, thereby improving the construction efficiency of the foundation pit site after resuming work after rain.

The setting of the anti-detachment clip 12 enhances the connection stability between the front end of the guide trough plate 3 and the concrete 4, thereby preventing the guide trough plate 3 from warping during use. The bottoms of the prefabricated box panel 2 and the guide trough plate 3 are poured with concrete 4, and the front side of the top of the prefabricated box panel 2 is inserted into the concrete 4. A water-blocking plate 5 is provided, and a rectangular slot 6 adapted to the water-blocking plate 5 is provided on the front side of the top of the prefabricated box panel 2. A plurality of columns 7 are arranged on the top of the prefabricated box panel 2. Two connecting pipe sleeves 10 are sleeved on the surface of the column 7. The connecting pipe sleeves 10 are fixedly connected to the surface of the column 7 by bolts. A cross bar 11 is provided between the two connecting pipe sleeves 10 located in the same horizontal plane. The two ends of the cross bar 11 are fixedly connected to the two connecting pipe sleeves 10 by screws respectively. An embedded component 8 is provided at the bottom of the column 7. Two supporting jackets 9 are fixedly connected to the water-blocking plate 5 located in front of it by screws. Example

[0033] Combination Figure 1-4 The embedded component 8 includes an embedded spiral tube 81 embedded in the outer edge of the foundation pit 1 and the concrete 4. The top of the embedded spiral tube 81 penetrates the top of the prefabricated box plate 2. The top of the surface of the embedded spiral tube 81 is threadedly connected with a fastening nut 83. The bottom end of the column 7 is welded with a connecting screw 84, which is threadedly connected to the inner cavity of the embedded spiral tube 81. The top of the surface of the connecting screw 84 is welded with a protective cap 85. The top of the prefabricated box plate 2 is provided with a fastening nut 83. The circular groove 82 and the protective cover cap 85 are engaged in the inner cavity of the circular groove 82. Through the setting of the embedded component 8, the circular groove 82 and the fastening nut 83 are used in combination to connect and fix the prefabricated box panel 2, thereby improving the stability of the prefabricated box panel 2 and the guide trough plate 3 after installation. At the same time, with the cooperation of the embedded screw tube 81 and the connecting screw 84, the column 7 is connected and fixed, so that the column 7 has a stronger supporting ability.

[0034] Working principle: When the utility model is used, the user implants the embedded screw tube 81 into the inner part of the outer edge 1 of the foundation pit, and then lays the prefabricated box plate 2 and the guide groove plate 3, so that the embedded screw tube 81 penetrates into the inner cavity of the circular groove 82, and tightens the fastening nut 83 on the top of the surface of the embedded screw tube 81. Finally, the concrete 4 is poured, so that the top of the prefabricated box plate 2 and the guide groove plate 3 are filled and supported. Then, the user rotates the connecting screw 84 into the inner cavity of the embedded screw tube 81 until the protective cap 85 is The water blocking plate 5 is inserted into the inner cavity of the circular groove 82, and then the user inserts the water blocking plate 5 into the inner cavity of the rectangular slot 6, fixes two supporting jackets 9 on the surface of the column 7, and fixes the supporting jackets 9 and the water blocking plate 5 with screws, thereby fixing the water blocking plate 5.
