Technical Field

[0001] The utility model relates to the technical field of support and reinforcement structures, in particular to a U-shaped groove foundation pit support and reinforcement structure. Background Art

[0002] A foundation pit refers to the space below ground level excavated for the construction of building (including structure) foundations and basements. Before excavating a foundation pit, the excavation plan should be determined based on geological and hydrological data, combined with the conditions of nearby buildings, and waterproofing and drainage should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope. The slope size is determined according to relevant construction project regulations. During the excavation of the foundation pit, it is generally necessary to install a foundation pit support device. The general foundation pit support device cannot adjust the angle to support the foundation pit, which will cause a gap between the support device and the wall of the foundation pit, resulting in a very low support quality of the support device.

A slider 11 is connected through the sliding connection, and a connecting plate 2 8 is fixedly connected to the slider 11. The end of the connecting rod 6 away from the support plate 7 is hinged on the connecting plate 2 8. The telescopic rod 4 pushes or pulls the cross plate 5 to drive the two groups of connecting rods 6 to rotate. The rotation of the two groups of connecting rods 6 can drive the support plate 7 to rotate on the base plate 1, so that the angle of the support plate 7 can be adjusted. Therefore, such a setting can adjust the angle of the support plate 7 according to the angle of the U-shaped foundation pit, so that the support plate 7 fits tightly on the wall of the U-shaped foundation pit, thereby improving the support quality of the support device.

[0027] The two ends of the base plate 1 are fixedly connected with mounting plates 12, and the mounting plates 12 are slidably connected with plug posts 13. The base plate 1 is fixedly connected with universal wheels 14. There are four groups of universal wheels 14, and the four groups of universal wheels 14 are evenly distributed at the bottom of the base plate 1. The base plate 1 is fixedly connected with a support rod 15, and the end of the support rod 15 away from the base plate 1 is fixedly connected with a push rod 16. The base plate 1 is fixedly connected with a hanging rope 17, and the material of the hanging rope 17 is nylon. The shape of the support plate 7 is semicircular, and the diameter of the support plate 7 is larger than the width of the base plate 1. The support plate 7 is located directly in front of the push rod 16.

[0028] Working principle: First, the support device can be sent into the foundation pit by hanging the lifting rope 17 with a rope, and then the worker can push the push rod 16 to push the support device to the appropriate place, and use a hammer to insert the column 13 into the ground to fix the support device on the ground, and then start the hydraulic rod 3 according to the angle of the foundation pit wall. The output end of the hydraulic rod 3 drives the telescopic rod 4 to extend and retract, and the telescopic rod 4 extends and retracts through the cross plate 5 to drive the two sets of connecting rods 6 to rotate. The rotation of the two sets of connecting rods 6 causes the slider 11 to slide on the slide groove 9. At the same time, the two sets of connecting rods 6 drive the support plate 7 to rotate, so that the angle of the support plate 7 can be adjusted, so that the angle of the support plate 7 can be adjusted according to the angle of the U-shaped foundation pit, so that the support plate 7 fits tightly against the wall of the U-shaped foundation pit, thereby improving the support quality of the support device.
